| Title: | Design for Six Sigma Through Statistical Simulation Methods |
| Abstract: | The United States Navy has identified the need to develop innovative technologies that reduce the costs of manufacturing weapon systems and components. This requires a commitment to using statistics and design of experiments (DoE) methodologies to fully understand and characterize manufacturing processes. The vast amount of data required for full process characterization combined with complex statistical analysis often makes this practice prohibitive for most computer-aided systems. This proposal by AET, Inc., directly addresses dual use methods for achieving advanced industrial practices such as six sigma manufacturing in both the military and the private sector. A practical six sigma design system can be achieved by integrating existing tools and techniques in a unique way that achieves the goals of both the Navy and AET, Inc. The environment to perform this integration is named STADIUM. The use of STADIUM and its design of experiments statistical analysis capability will allow extraction of six sigma design and process parameters to be used in the performance simulation and evaluation. |

| Title: | Large Area Thin Film Corrosion Resistance via CCVD |
| Abstract: | Corrosion damage to aluminum structural components is very costly to both the government and commercial industry; viable treatments and/or protective procedures are required to limit it. Paint and related conventional coatings are commonly used to combat corrosion, although such coatings often may degrade quickly requiring frequent reapplication or touch-up; this is expensive and labor-intensive, especially in the field. Higher performance conversion coatings are prepared with processes which use hexavalent chromium, now considered to be a major health and environmental hazard. Thus, there is a compelling need for alternative, environmentally benign, low-cost coating technologies to protect aluminum components and structures subjected to corrosive environments. In addition, reduced weight is desired. MicroCoating Technologies, Inc. proposes to develop its safe, clean, economical Combustion Chemical Vapor Deposition (CCVD) process to fabricate high-quality, dense, pinhole-free, metal-oxide thin films as replacements for the chromate conversion coatings. The patented CCVD method is an open atmosphere deposition system capable of true heterogenous vapor deposition of dense, high quality films but at a fraction of the cost of the traditional vacuum processes, Chemical Vapor Deposition and Physical Vapor Deposition (PVD). Since CCVD processing is not confined to a reaction chamber or furnace, coating of large objects such as aircraft structural components is viable. We have already completed experimental work on low temperature deposition of CCVD coatings on aluminum and copper substrates. Our trial coatings display excellent performance as corrosion-barriers under wet conditions in tests performed by both Battelle (1300+ hours of saltwater spray) and an industrial partner (30 day SWAAT). We will detail these preliminary results further in the proposal. In Phase I, we will build on this initial success and work with our industrial collaborators to develop CCVD metal-oxide coatings with negligible weight for protection of aluminum structural components in both military and commercial applications. Phase I success will lead to a Phase II program to scale and automate the CCVD process for high rate, low cost production. This SBIR research will be planned, developed and commercialized through Phase III in collaboration with our industrial partners. |

| Title: | Technology for Affordability |
| Abstract: | The towed array capabilities of the US Navy combine high reliability, high channel count, long aperture and low self noise to provide an underwater acoustic superiority not matched by any other Navy. This superiority has also brought with it unwanted high production costs for these arrays. The next generation of Naval towed arrays with increasingly larger aperture may be out of the reach of a cost conscience Navy. The innovative technology described in this proposal will dramatically reduce the costs of providing this underwater acoustic superiority by automating the construction of towed arrays. It will provide a continuous array design ideally suited for optical hydrophones and telemetry. It will dramatically reduce the number of modules used to form an array and eliminate the fiber and strength member splices required at these terminations. The technology uses machine wrapped open cell foam, machine wrapped optical fibers which carry the telemetrized hydrophone signals, machine installed internal strength members, and a continuously extruded outer hose wall. This automated construction maintains high array reliability in a low flow noise hydroacoustic design while dramatically reducing the fabrication costs. |

| Title: | Manufacturing Technology for Affordable Composite Structures |
| Abstract: | Ebert Composites Corporation (Ebert) proposes to develop an advanced combined pultrusion and machining concept capable of producing affordable precision machined pultruded components for use in large composite structures. Previous research efforts have shown the merits of composite truss structures using a novel interlocking system developed by Ebert. The system allows assembly of structures without adhesives, bolts, or joint reinforcing material. Large, very high strength, easy to assemble structures are possible using relatively low cost materials. However, extensive precision machining of the base pultruded material is required to produce individual components of a structure. Previous research has also shown that this will require multiple machining steps separate from the pultrusion process to produce the strongest possible joint. These machining steps are time consuming, which restricts the ability to produce low cost components. During Phase I, Ebert proposes to design a pultrusion process that seamlessly integrates high speed precision machining. General machining concepts will be developed and tested using in-house equipment with a goal of demonstrating the capability of synchronized machining of pultruded components. The option period would develop a test truss structure and a pultrusion/machining specification as a lead-in to Phase II development. |

| Title: | TERFENOL-D Lamination Process Cost Reduction |
| Abstract: | All high performance TERFENOL-D sonar devices require the drivers to be laminated for eddy current control. The process of laminating TERFENOL-D to present interlamina resistivity requirements results in low yields due to considerable material loss and is, therefore, a wasteful process. The objective of this program is to define and experimentally verify accurate interlamina resistivity levels for high performance TERFENOL-D drivers which also ensure acceptable power losses. Phase I will conclusively prove analytical theory which predicts relative independence of driver performance upon lamina conductivity. Proving that existing requirements can be safely relaxed, will have an immediate effect on TERFENOL-D high performance sonar driver yields resulting in almost 50% cost reduction. |

| Abstract: | The purpose of this Phase I proposal is to verify the feasibility fro use of a robotic laser fabrication and repair system and to show how this innovative technology application will reduce costs of Warfighter systems and components, and improve performance and reliability. This system will provide impact in the shipyard, on the factory floor, in the aircraft repair depot and onboard ship. The number of potential military applications for this technology is very large, and provides the potential for significant savings of resources and time in production of military hardware, fabrication of defense relate components, and erpair and maintenance of esisting systems. Based on the integration of existing techologies into an innovative new computer-based process modeling and planning environment, this development will provide a demonstration of the apllications in Phase I. It can be applie dto large-scale or few-of-a-kind manufacturing, or fast production of long procurement lead-time parts, for the rapid prototyping of components that have real evaluatable and testable form & fit capability, and for repair and maintenance thru reforming of damagd & distorted parts. The system that will be developed is generally based on COTS hardware; and both the hardware and software is reconfigurable; The operator environments are intuitive, interactive and graphical. It will use a relatively low-cost PC computer-based 3D-CAD technology from Intergraph Corporation that is fully compatible with the Integrated Ship Design System currently under development for the Navy by Intergraph. |

| Title: | Induction Carburizing--A Novel Cost Effective, Environmentally Safe, Affordable Technology |
| Abstract: | Carburizing of steels to improve wear resistance is an old but widely used process. Current furnace technologies are expensive because their extensive requirements for time, space, labor, materials, energy and maintenance, and are harmful to the enviroment due to active atmosphere and heat losses. Separate equipment is needed to establish desired properties in the part case and core. The proposed New Induction Technology (patent pending) will dramatically increase customer affordability by reducing the costs of manufacturing and repair of many important parts of aircraft, rotorcraft, ships, submarines, weapon systems, and correspondingly their life-cycle costs. Induction Carburizing can rapidly produce both local and overall protective surface layers not only on steels but on Ti base alloys. There are no restrictions as to part shape or dimensions. The carbon content, depth of penetration, microstructure, and properties can be obtained in seconds or minutes and adjusted as required for reliability and longevity increasing. Unlike current technologies the core temperature and properties remain unchanged, required subsequent cooling, quenching, and reheat treatment can be done simultaneously in the same installation. Sanova-Polytech, Inc. has outlined a comprehensive Phase I Program to show the feasibility of Induction Carburizing and to perform a preliminary cost analysis for transition of this New Technology to commercial usage. |

| Title: | Management Tool for the Battlespace Environment: |
| Abstract: | An HLA tool, i.e., a battlemaster, is needed to enable a user to easily configure, control, and monitor a large-scale distributed exercise,. MäK Technologies has substantial expertise in HLA, is the leading supplier of HLA tools, and is a developer of networked games containing battlemaster components. Therefore, MäK is the ideal candidate to develop the battlemaster required by the M&S community. MäK Technologies will develop an HLA Battlemaster that supports configuration, control, and monitoring of both federations and individual federates. The Battlemaster will provide access to the required standard set of RTI's services, the Management Object Model, and the federation's FOM. In addition, the Battlemaster will provide a specialized set of services through its Battlemaster Application Programmer Interface (BAPI), which supports federate-specific plug-ins. MäK's Battlemaster will be based on MäK's commercial HLA Plan-View-Display, lowering time requirements, cost, and risk, while providing additional capabilities that are not ordinarily found in a battlemaster. At the beginning of Phase I, MäK will interview operational users to determine the functional requirements of the HLA Battlemaster. These requirements will guide development of an object-orientated design specification. With the newly created design and MäK's existing commercial PVD, MäK will create an initial Battlemaster prototype. To complete the spiral development cycle, MäK proposes a Phase I option to develop a test federation. We will iterate upon four components (requirements, design, prototype, and test federation) during Phase II to create a powerful, robust, flexible HLA Battlemaster. MäK can achieve all this in Phase I by leveraging existing tools and technology, and by applying its experience in both HLA and design and development of battlemasters for networked games. |

| Title: | VISGEEN: Virtual Interactive Scenario Generation and Execution Environment |
| Abstract: | The Modeling and Simulation (M&S) community is faced with increasing requirements to promote interoperability and reusability. To address this issue, DoD has defined the High-Level Architecture (HLA) as the standard to which models and simulations must conform. The HLA provides the infrastructure that allows conforming models and simulations to interact. However, neither the HLA or current simulation environments provide the high level coordination capability needed for the activities involved in creating and managing complex, synthetic, battlespace environments. In this SBIR, Modus Operandi (formerly Software Productivity Solutions) proposes to leverage our experience in distributed simulation and complex engineering environments to develop a Virtual Interactive Scenario Generation and Execution Environment (VISGEEN). VISGEEN supports the full simulation life-cycle of the synthetic battlespace environment, from scenario construction using integrated models and simulations, to run-time initialization, monitoring, control, and visualization of the participating simulations. In Phase I, Modus Operandi will integrate VISGEEN with existing M&S assets and use them to create a scenario for execution. VISGEEN will then initialize, manage, and visualize the scenario executing within the context of the HLA. This prototype will provide a solid foundation for Phase II full-scale VISGEEN implementation. |

| Abstract: | This effort will leverage DTI's existing PowerMod` Solid State Switching technology to develop a 20 kV, 100-400 kHz pulse modulator for advanced W-band pulse Doppler radar applications. Key features of this effort will be the extension of solid state switching techniques to 100-400 kHz at high support enhanced effective surface-based radar detection and tracking of low RCS / low altitude targets such as cruise missiles, which currently pose a significant threat to naval assets. Additionally, this effort will demonstrate voltage regulation better than 1 part in 10,000 in a pulsed power environment. This level of voltage regulation is critical to the performance of high power RF tubes, such as klystrons and TWTs, in applications where phase stability is a key performance parameter. |

| Title: | A HIGH-REPETITION RATE PULSE MODULATOR FOR HIGH-POWER |
| Abstract: | The proposed program will concentrate on the design of pulse-amplitude modulators using innovative architectures to overcome the limitations of conventional designs in driving predominantly capacitive loads, such as the modulating anodes of high-power microwave vacuum tubes. The design will necessarily be capable of operation at high pulse voltage levels and at high pulse repetition rates. Typical of such an architecture is the "quasi-resonant" arrangement described in 11.1.8 of "High-Power Microwave-Tube Transmitters" (Reference 1 of N98-003), wherein the capacitance associated with the modulating anode is charged and discharged through a resonating inductor, or inductors, in a sinusoidal fashion, transferring stored energy rather than dissipating it. There are numerous variants of this concept which must be investigated in order to determine an optimum design depending on the type of electronic switches and how they are used. The program will include the evaluation of the various available electronic switches, including Field-Effect Transistors (FETs), Insulated-Gate Bipolar Transistors (IGBTs), Silicon-Controlled Rectifiers (SCRs), conventional triode and tetrode vacuum tubes, and the "Crossatron" gas-filled switch. This evaluation will concentrate on selecting the best electronic switch for this application. The effort will also include breadboarding of appropriately scaled portions of complete switches. |

| Title: | Long Life Thermal Battery for Sonobuoy |
| Abstract: | The prospects of significantly enhancing antisubmarine warfare (ASW) sonobuoys require exponential improvements in thermal battery capability. The fused-salt primary battery LiSi/CoS2 has shown tremendous progress in meeting the advanced requirements. Adaptation of recent advances in high-rate rechargeable thermal batteries provides a cost-effective approach for fully meeting size 'A' sonobuoy performance objectives. Specifically, an innovative super insulated container (vacuum/multifoil, which is 10-100 times as effective as Microtherm) promises to extend operating times beyond 4 hours to 12 hours. Reduced thickness of insulation would allow increased battery stack diameter and capacity (by 25%) to exceed 200 ping-seconds or power at greater than 13 kW. Rechargeable thermal battery peripheral seals, thinner (by 50%) fiber-separator; FeS2-CuFeS2 cathodes with 25% higher capacity density and lower-melting electrolyte are options for further increasing 'A' size sonobuoy battery performance and life. Battery life and performance could be doubled concurrently. Phase II would demonstrate the improved sonobuoy battery and aid in commercialization of the rechargeable thermal battery. A "dual-use" objective enables cost-effective deployment of the long life thermal battery for the 'A' size sonobuoy. |

| Title: | Flexible Shear Stress Smart Skin for Submarine Applications |
| Abstract: | Physical Optics Corporation's (POC) objective is to develop a flexible MEMS-based shear stress sensor for Navy radio-controlled submarine model experiments. An array of transducers can enhance the flow characteristics of model hulls and control surfaces. POC proposes development of a novel waterproof shear stress transducer that can detect the direction and magnitude of shear stress under a water pressure environment with high spatial and temporal resolution. The device can assist with evaluating the hydrodynamic merit of new submarine designs. A robust stress transducer uses a floating element, coupled with fiber Bragg gratings (FBGs), which is deflected when exposed to fluid flow. A transducer uses Bragg gratings etched onto a symmetrical pair of fibers. A pair of FBGs balances deflection of the floating element, thereby reducing noise caused by the temperature/pressure effect. Gaps within the exposure surface of the floating element are covered by a silicon rubber thin film to resist water contamination. In Phase I, proof-of-concept will be demonstrated for waterproofing techniques on a MEMS-based transducer. A smart sensor network will be deisnged to address a large number of proposed devices to build a solid foundation for Phase II. |

| Title: | Global Shear-Stress Distribution Using Water-Proofed Hot-Film Constant Voltage Anemometer (CVA) |
| Abstract: | Boundary-layer flow characteristics, such as the location of the laminar-to-turbulent transition, flow separation and flow reversal regions, as well as surface shear-stress distribution on marine vehicle models, will be measured using micro-thin, multi-element hot-film sensor arrays coated with electically non-conducting, water-proof polymer material. Tao Systems' Constant Voltage Anemometer (CVA) instrumentation system will be adapted for under-water applications to obtain high sensitivity and high dynamic response at low sensor currents. The low power dissipation in hot-films operated with CVA will significantly reduce or eliminate bubble formation, as well as corrosion causing electrolysis associated with conventional techniques. The high signal-to-noise ratio of CVA, coupled with large bandwidth, even at low sensor currents will eliminate most of the problems encountered by conventional anemometers in under-water applications. Furthermore, since the power dissipated by hot-film sensors in the CVA-mode of operation is linearly proportional to the voltage output (and not to the square of the measured output voltage, as in constant temperature anemometer), an order of magnitude reduction in measurement error will result with the proposed innovation. The feasibility of the proposed approach will be demonstrated during Phase I by conducting tests on an instrumented model in a water tunnel. |

| Abstract: | There exists a large need in the fluid mechanics community for waterproof micro shear stress sensors. The United Micromachines MEMS hot-film shear-stress sensor with underlying vacuum cavity is the only proven laboratory prototype micro shear stress sensor. In addtion, these sensors can be fabricated on a flexible substrate that can conform to curved test surfaces. With additional effort, the sensor technology can be advanced to the point where the sensor will be a commercially viable product. One of these efforts must be directed in the direction of waterproofing, which will allow the sensors to be used both underwater and in wet (ie raining or very humid) conditions. Initially, United Micromachines will concentrate on developing and testing waterproof coatings for use on the already developed sensor. The testing will concentrate on the waterproofness and pressure effect on sensor performance. In Phase II, United Micromachines will develop the packaging and electronics integration schemes necessary for acceptance by the fluid mechanics community. |

| Title: | Polymeric Hose Health Inspection Using Microwave NDE Techniques |
| Abstract: | Hoses are critical to the operation of hydraulic, power train, and auxiliary machinery aboard ship and in industrial applications. This project will develop a hose inspection tool to economically and practically assess hose health in place. Reliable inspection of hoses reduces maintenance costs while decreasing the rate of hose failures and related accidents. Microwave methods for hose nondestructive evaluation (NDE) can identify critical hose defects at low cost with minimal operator training. Microwave hose NDE can be done using portable handheld devices roughly the size and weight of a flashlight. Microwave inspection is based on the change in dielectric properties associated with hose defects like delamination, disbonding, and wall thinning. These changes are detected by sensing reflected microwave energy, and complex signal processing routines are not required to observe them with high reliability. Microwave NDE is done in real time - results are immediate and can be as simple as the blink of an indicator light - so position recording or complex scanning equipment is not necessary. Development of microwave NDE for hose inspection will result in a battery powered NDE tool - more like a battery operated drill than a computer driven system - and as such has a very high potential for commercial success in both Navy and industrial applications. TRI/Austin has committed to funding - at no cost to the project - a business study by an MBA candidate team to map the path for moving microwave hose NDE to the commercial market after development. |

| Abstract: | There is a need for a robust, non-invasive system for the measurement and recording of single-event (non-repetitive) time-dependent high temperatures. Measurement periods for these applications can range from microseconds to several hundred milliseconds. Individual measurements must be made on the order of every microsecond or more frequent. A2Z Technologies Corporation proposes to design and develop instrumentation which is broadly applicable to high-speed temperature measurement applications for Government (i.e., DOD, NASA, DOE) and industrial applications (Engine manufactures, manufactures of explosives, etc.). Specific capabilities for the proposed thermal imager are 1) non-intrusive, high temperature measurements, 2) multiple point (256 x 256) simultaneous measurements, 3) time-resolved measurements with controllable sampling intervals (1 ms - 50 ms), and 4) operate in harsh physical and EMI environments. During the proposed 6 month effort, A2Z Technologies Corporation will perform initial measurements at Naval test facilities, test the interference environment produced by the pulsed x-ray sources, design the prototype instrument, and develop, test, and demonstrate a Phase I breadboard system. All Phase I activities are for the purpose of proving the system feasibility. In addition, a Phase I option is proposed that includes 1) additional system testing and 2) prototype system design. |

| Title: | Inlet for Turbofan Powered High Performance Tactical Missiles |
| Abstract: | The duPont Aerospace Company, Inc. proposes to design an innovative inlet suitable for a hypersonic cruise missile. The innovative features consist of an inlet cowl which rotates outward from the retracted position to accommodate the airflow requirements of the engine, a coordinated variation in throat area and possible elimination of boundary layer bleed. The retracted position allows the engine to be closed off for hypersonic glide operation, and the various extended positions match the engine airflow requirements over the Mach number range from zero to six. The coordinated throat area variation matches the contraction necessary to reduce the inlet Mach number to a low value prior to the final normal shock. Boundary layer bleed requirements may be eliminated providing a more efficient overall solution if the resulting distortion is acceptable for the turbine engine. The Phase I work consists of CAD design and associated aerodynamic analysis using duPont proprietary methods which have been thoroughly proven in the NASP program. The final result is expected to be an optimized inlet that meets all system requirements. |

| Abstract: | Air transportability, buoyancy and acoustic signature of future USMC/Navy 16 and 30 ton class tracked vehicles such as the Advanced Amphibious Assault Vehicle (AAAV) will be greatly enhanced if lightweight track shoes are developed to replace the existing forged, surface hardened steel components. Foster-Miller proposes to develop a tailored metal matrix composite (MMC) track shoe/pin component that will match the wear and strength performance of the current steel shoe at less than half its weight. Further, our MMC fabrication method (pressure casting) uses low cost nonstructural tooling, achieves net shape parts and is scaleable, which will produce high performance and cost-effective components. The Foster-Miller team will include a major foundary who is responsible for the design of track components for the AAAV, and a targeted component producer (beyond Phase II). In Phase I, Foster-Miller will produce MMC specimens for mechanical and tribological testing, and a scaled "show and tell" demonstration article to prove the shape capability. In Phase II, Foster-Miller will optimize materials and processes involved, prove repeatability and consistency in track component performance, and demonstrate cost, weight and performance benefits over the baseline component(s). |

| Abstract: | The Marine CorpsÇ next generation amphibious assault vehicle requires improved power generation capabilities due to increased power demand. Versatility (e.g., capability to drive two generators in parallel), high efficiency, and temperature independent voltage regulation are the goals of this development. Unique Mobility, Incorporated is ideally positioned to achieve these goals due to 15 years experience in applying small, lightweight, and efficient brushless permanent magnet (PM) motors and generators within vehicle applications. Unique is currently involved in many hybrid electric vehicle motors and generator programs, collaborating with Orbital Engine Corporation, Northrop Grumman, Houston Metro Transit Authority, US Department of Transportation, Deere & Company, and DARPA, as well as others. Within generator applications specifically, UniqueÇs method of delivering constant voltage over a wide range of generator speeds and temperatures results in a minimum power electronics and delivers high efficiencies, usually exceeding 90% across a wide band. This experience is vital to improving the AAAV power generation system, where the Phase I goal will be to design an optimized generator with associated electronics. System efficiency in excess of 85% across the operating region is anticipated. A set of conceptual drawings along with prototype and production cost estimates will be included in the Phase I report. |

| Title: | Multiple Beam Antennas with Semi-Constrained Beamformers |
| Abstract: | A mobile satellite communications link operating from vehicles on-the-move would provide significant benefits to the Marine Corps in the battlefield environment. The antenna should be capable of simultaneous and rapid tracking of two satellites while the vehicle is in motion over rough terrain, as well as providing ultra-wide bandwidth (C-band through Ku-band), medium to high gain, low profile, rugged, minimal size and mountable on military vehicles. Affordability is also a significant issue. This Phase I effort will focus on multiple beam antennas with semi-constrained beamformers because, with their inherently wide bandwidth, multiple beam capability, and relatively low cost, they offer the most realistic and affordable approach to meeting the above requirements using current state-of-the-art technology. The feasibility of several innovative beamformer and aperture approaches will be investigated and compared with existing designs. Results of a preliminary evaluation using a computer model programmed for this proposal are included in the proposal. The ultra-wide bandwidth requirement poses design challenges due to mutual coupling between elements and intermodulation. The Principal Investigator has wide experience in array design and holds two patents for wideband phased array elements. |

| Title: | It's the Drop |
| Abstract: | How do you hit a two-meter square target 500 meters away with a subsonic, unguided SMAW-D missile? At 100 meters, drop is about as important as other factors. At 500 meters, other factors have increased linearly but drop has grown by a factor of 30 and is the dominant factor. Even a 9mm revolver can hit the above target if you get the drop right. To compensate for drop, you need to know range AND velocity. R can come from either a spotting rifle or a laser rangefinder. A commercial, off the shelf laser rangefinder available for less than $200 may do a better job than a spotting rifle. While usable as-is, we explore integrating this rangefinder into the SMAW-D launch system. Launch velocity of the missile drops sharply with temperature and this problem must be addressed. If the velocity of a cold missile not only drops but is inconsistent, then the only answer is a guidance system. We explore a simple, no computer guidance system to compensate for gravity. While this system can easily be enhanced, it solves the immediate problem defined above. |

| Title: | High Accuracy GPfog Azimuth and Attitude Sensor |
| Abstract: | KVH Industries proposes to deliver a high precision GPfog azimuth and attitude sensing system based on fusing three low cost sensor technologies: ultra short baseline carrier phase measurement GPS utilizing low cost GPS chip technology; uniquely affordable three-axis KVH E-Core Fiber Optic Gyros (FOGs); and a micro-machined commercially available accelerometer sensor package. The fiber optic rate sensors will be fused with GPS azimuth/attitude measurements and accelerometer inputs to increase system bandwidth and robustness and to provide immunity to short term GPS outages. During platform motion, the proposed system will use the change in position inputs from multiple low cost GPS chips to calculate a backup azimuth input to the carrier phase measurement, including stored heading backup during vehicle stops. The proposed three axis attitude and azimuth system will deliver better than 0.4 RMS degree accuracy at a per-unit parts and labor cost below $2,000 (sell cost under $7,000) in small quantities. KVH's proven experience in GPS product fusion (KVH GPS/Compass TACNAV and GPS/FOG Continuous Positioning System), combined with our low cost, robust, low drift FOG technology, make KVH uniquely qualified to solve the solicited non-magnetic high accuracy azimuth requirement. |

| Abstract: | A notional concept for an Advanced Sigint System is proposed. Features of the concept include use of COTS hardware for most componentry, and use of highly innovative Sonetech algorithms for ESM/ECM resource management, signal classification, Direction Finding, and jammer/ECM control. A novel technique for emitter location in the "urban canyon" environment is proposed in the basic effort; its counterpart in active jamming would allow selective jamming of the emitter while minimizing"electronic fratricide". Study of the active counterpart is proposed as a study option (p.12, para(3)). An overall design implementation will be selected which will maximize flexibility, modularity, and cost-effectiveness of the baseline systems, with growth potential to allow the optional capability to be added later. |

| Abstract: | The Radio Reconnaissance Team of the Marine Air-Ground Task Force must retain the cutting edge in the tools of their trade amidst rapidly changing technology. This assimilation of technology will enable him to conduct electronic attack with precision and effectiveness. The Radio Reconnaissance Team member must have equipment that is versatile, easy to configure, easy to carry, easy to operate, reliable, simple to maintain and support, durable, and functional under the most severe conditions. A self-contained, modular EA system will be most effective in supporting the intelligence gathering mission as it will interface with the Marine Corps Reconnaissance Equipment Program SIGINT Suite-1 (RREP-SS-1). The proposed module will include on-board power, remotely tunable transmitters, and remotely controlled power output. This proposal outlines a four-task approach toward rapid commercialization. The first three tasks will form the basis for the first 180 days of this research effort while the fourth task may be included in a three-month option to the contract. The tasks are: 1) Perform a survey of commercial components, requirements, and operators. 2) Perform exploration / experimentation on the implementation of microprocessor controlled solid state circuitry. 3) Perform a complete design analysis of needed hardware. 4) Conduct a proof-of-concept demonstration. The demonstration will provide a basis on which to determine the technical merit of this approach. |

| Title: | A Stand Alone Environmental Corrosivity Measurement System |
| Abstract: | Corrosion problems experienced by military equipment are severe and expensive; estimates for the Navy alone are more than $1 billion annually. To reduce these costs it is imperative that equipment be monitored for exposure to corrosive environments. Quantitative monitoring programs will help to better understand how to best mitigate the effects of these environments. The opportunity presented here is the development of an integrated environmental monitoring system so that data which characterizes the corrosivity of the environment can be gathered. The instrument will incorporate an innovative integrated sensor suite capable of monitoring temperature, humidity, rainfall conductivity, and corrosivity (e.g. galvanic activity) data over a wide-range of operating conditions. The data acquisition system will be based on a small but sophisticated Micro- Computer Unit which will gather data over long periods of time. Use of this advanced technology will result in a small, lightweight system which can be used in shipboard, airborne, and ground station applications. The primary focus in Phase I is to prove the feasibility by 1) integrating sensors which can accurately and reliably measure these parameters into a stand-alone package using thin-film deposition techniques and 2) demonstrating a prototypical signal conditioning and data acquisition system with remote data retrieval capabilities. |

| Title: | Intelligent Coatings for Corrosion Detection Using Fluorescence Lifetime Imaging |
| Abstract: | Systems & Processes Engineering Corporation (SPEC) and Dr. Richard E. Johnson of LeTourneau University proposes to develop a method to encapsulate and embed corrosion sensitive dye molecules into a intelligent aircraft primer coating. We intend to detect the fluorescence changes of dye molecules interaction with corrosion by-products by using frequency domain fluorescence lifetime imaging (FLIM) technology. The system is based upon the determination of the fluorescence lifetime contrast images of the intelligent corrosion by measuring the amplitude and phase shift of the fluorescence emission relative to an amplitude modulated excitation light source, thus avoiding many of the technical difficulties associated with an intensity measurement system. We intend to also investigate and develop an encapsulation method for these dye molecules based upon previous SPEC work in silica-gel technology. SPEC and Dr. Johnson has extensive experience implementing fluorescence lifetime measurement systems and in the development of intelligent coatings. SPEC has manufactured, demonstrated, and delivered a number of corrosion detection and monitoring systems to NASA Langley, US Army Missile Command, and the Naval Air Warfare Center, Aircraft Division at Patuxent River. |

| Title: | Improved Leak Location System for Aircraft Internal/Integral Fuel Tanks/Cells |
| Abstract: | Program objective is to develop a television system for identifying fuel tank leaks. This leak detection method uses a near infrared camera with illuminator to observe gas flow through any small breaches in the fuel tank wall. System performance is based on the physical principle that reflected scene irradiance is reduced in any area where an illuminator's spectral bandpass traverses a flowing gas with the corresponding absorptive bandpass. In subsequent discussion this leak identification system will be referred to as the Eclipse Detection System (EDS). Proof of concept will be accomplished by designing and testing a prototype EDS that detects the flow of selected unheated or cooled gas through fuel tank leaks. These prototype tests will show EDS's to be: (1) comparable in size and ease of operation to a conventional camcorder, (2) less expensive than proposed or currently available methods, (3) more user friendly, and (4) will provide improved imagery with leak areas shown as black spots and/or plumes on a TV monitor. Conversely, leak detection systems that rely on heated air or gas emissions require a more costly and complex setup to image and control the heated trace gases. Heated trace gases may be corrosive to some fuel tank surfaces. |

| Title: | Cycloidal Propulsion for UAV VTOL Applications |
| Abstract: | The proposed effort will result in the development and wind tunnel validation of a universal pitch cycloidal propeller system which can provide efficient vertical takeoff or landing (VTOL) UAV propulsion. This form of propulsion is currently in use in marine applications, and has been studied by major aircraft manufacturers and the military. Study and wind tunnel test results support the concept; however, until the advent of the micro-computer and associated motion control technologies, efficient cycloidal propellers were only feasible for relatively narrow speed ranges. This effort will capitalize on computer control to provide a universal pitch cycloidal propeller that will allow efficient flight across a wide range of flight speeds and conditions. Cycloidal propulsion provides a unique 360-degree directional flight capability through use of a low-velocity, high-volume flow technique of exceptional efficiency. The cycloidal propeller, which provides both thrust and lift, can make near instantaneous change in thrust direction without re-orientation of the propellers plane of rotation. Major advantages of this system include efficient hovering flight, low-noise signature, near-instantaneous change in thrust direction, wide speed range, safety, and packaging. BOSCH Aerospace, Inc., has teamed with the Raspet Flight Research Center of Mississippi State University to conduct Phase 1. The research will encompass systems engineering, mechanical design, computer modeling, control algorithm development, fabrication, and wind tunnel tests. A fully functional propeller and control system will be completed and tested during Phase 1. Documentation from this effort will include study, design, and tests results. |

As a designer and fabricator of CMC components, Refractory Composites, Inc. (RCI) agrees that SiC CMC materials and fabrication technologies are of the maturity level for use as high temperature components in turbine engines. In order to truly capitalize on the benefits of CMC components, they must be successfully bonded to state of the art superalloys. In this proposed SBIR program, RCI will develop and demonstrate fusion joining techniques for CMCs to superalloys for operation at temperatures above 700oC and capable of withstanding the harsh corrosive environments encountered in Navy turbine engine applications. In addition we will develop stress analysis tools capable of use in designing joined components. RCI has already developed methods of bonding CMC components to metal components for other applications. |

| Title: | Thermoset Resin Development for In Situ Fiber Placement |
| Abstract: | Fiber placement is a technique developed for fabrication of thermoplastic matrix composite structures, but it has been applied to layup of complex thermoset composite structures which are difficult to produce using other methods. It has been used successfully to produce several such structures, eliminating or minimizing problems such as fiber waviness (or marcelling), fiber shifting, resin migration, disbonds and voids. Currently, however, successful use of this technique for thick parts depends upon repeated debulking during fiber placement, and a lengthy autoclave cure cycle is required after fiber placement is completed. Foster-Miller proposes to modify commercial thermoplastic toughened prepreg tape to eliminate these debulking and autoclave cure requirements. A combination of staging, preconsolidation and creation of a highly reactive surface will be employed to produce a prepreg tape capable of full in-situ cure during fiber placement. Foster-Miller has formed a team with aircraft primes Bell Helicopter and Lockheed Martin to realize development of this low cost fabrication process. The Phase I program will culminate in the use of this modified prepreg for in-situ cure during fiber placement of a representative composite subcomponent during the optional task. |

| Title: | Biofidelic Lumbar Spine for Human Response to Aircraft Ejection and Helicopter Crash |
| Abstract: | Spinal injury (vertebra fracture) during aircraft ejection or vertical helicopter crash is a serious problem due to the human body's inability to tolerate excessive +Gz acceleration. Although anthropomorphic test devices (ATD) or manikins have been used to assess, develop and standardize ejection seat and crash safety, they do not represent the spinal response under high acceleration loading. Flex Technology has designed and developed an innovative flexible structure which has the potential to mimic the properties of the human spine for incorporation within an ATD. It is proposed to review the current staus and properties of ATD spinal units as well as human vertebal specimens, research and document the spine's response to high impact loading, to design and develop using dynamic computer modelling an innovative flexible structure that has the stiffness properties comparable to experimentally determined vertebral stiffness, and to construct prototype units for mechanical testing and response verification. The key elements of the proposed unit is its simplistic, continuous, one piece design, and ability to customize the mechanical properties. The unit will be computer designed based on experimentally determined vertebral properties. Phase II developments will include a multi-degree of freedom spinal unit, a female unit, whole body response testing and verification, and further testing in anticipation of government acceptance. In order to accomplish the task with the highest degree of success and scientific ability, the offeror has assembled a team of consultants that are World renown in the field of spine and impact biomechanics. |

| Title: | Thermasorb Enhanced Microclimate Cooling Suit |
| Abstract: | Chemical/Biological (CB) protective ensembles impose a thermal burden on aircrew, which not only limits mission time but poses a physiological danger to aircrew in even moderate operating environments. The thermal loads placed on these personnel may be reduced through the use of microclimate cooling systems. Unfortunately, to provide effective cooling, such systems must usually make compromises in weight, portability, effectiveness, or comfort. It is possible to greatly enhance the cooling efficiency of microclimate cooling suits through the use of Thermasorb additives. Thermasorb additives consist of micro-encapsulated phase-change materials that are capable of absorbing large amounts of heat without changing temperature. These additives can improve microclimate cooling suits through the use of modular cooling packs or a slurry-based system. Frisby proposes to design, build, test, and demonstrate three laboratory-scale Thermasorb systems. A system that incorporates bulk Thermasorb microcapsules in modular units that will absorb heat from a secondary circulating unit, a Thermasorb slurry system that will absorb heat directly from the heat source, and a hybrid (active/passive) system. |

Identification of essential features in modeling military fault tolerant computing systems and for commercialization, and demonstration of a theoretical basis for modifying existing tools or developing new tools with a potential for commercialization and for integration with a performance modeling tool. Two approaches will be used in the evaluation: analytical evaluation, mostly based on the user's manual, and experimental evaluation by execution of the tool. In the experimental evaluation, the representative tools will be used to model actual fault tolerant systems. The results of this Phase I research will be a high- level design for modifying selected existing tools or developing new tools. The design will form the basis for the Phase II development of tools that are suitable for both modeling military fault tolerant systems and commercialization. |

| Title: | Passive Acoustic Sensor System for Marine Mammal Detection |
| Abstract: | Protecting marine mammals from harm during Navy explosive operations is a high priority. A dedicated sensor system for field mitigation that has a high probability of detection, is flexible and can be tailored to fit the scope of an exercise is highly desirable. A preliminary examination of the characteristics and behavior of marine mammals suggests that a unique dedicated passive acoustic sensor system could be developed from existing sonobuoy technology. It would have near 100% probability of detection and would be a cost effective adjunct to the existing technique of visual observations. A program is proposed for the development of a passive acoustic sensor and processor/display system meeting those criteria. A comprehensive analysis of the vocalization characteristics and behavior of cetaceans and other marine mammals will be used to determine system characteristics for optimizing detection and localization. Frequency range, source level, conditions that induce vocalizations and variety of sounds will be important criteria. Omnidirectional and directional sensors will be compared for detection effectiveness, complexity, number of sensors required and cost. Various processing schemes will be evaluated to determine the most effective method of detection and localization. The goal is to develop a practical, simple, cost effective and flexible system. |

| Abstract: | Dynamics Technology, Inc. (DTI) will develop and build a prototype geomagnetic reference sensor system (GRSS) to support advanced magnetic anomaly detection (MAD) for airborne submarine search. The GRSS is an off board system consisting of the reference sensor, auxiliary sensors for noise reduction, a sensor platform, and signal processing and noise reduction algorithms. It will suppress geomagnetic noise increasing the performance of airborne MAD. DTI has identified candidate sensors, auxiliary sensors, platforms, and signal processing and noise reduction algorithms. The candidate platforms are UAV, balloon, or buoy. Each platform has different sensor, auxiliary sensor, signal processing, and noise reduction requirements. A thorough system analysis will reveal the optimum GRSS from among the various candidate systems, and also demonstrate its feasibility. The primary measure of effectiveness will be cost per unit search area. The system analysis will build on DTI-developed system performance tools developed under previous Navy programs. Only after identifying the optimum GRSS will we assemble a prototype development team from the possible hardware vendor partners identified in the system analysis. In Phase 1 we will: (1) perform system analyses based on existing DTI models, (2) identify and characterize candidate sensor, platform, and processor systems and their operational constraints and costs in cooperation with potential vendor partners, (3) demonstrate system feasibility by modeling performance of a system based on identified components using best available sensor platform characteristics and a suitable processor mockup, and (4) determine Phase 2 prototype development requirements and vendor partners based on the feasibility analysis. |

However, all combinations of SAR, IFSAR, optical and IR imagery will be accommodated. determine tie-points in the multisensor images, and 2) determine and apply an affine transformation for 2D-to-2D image registration. An analysis will be performed to assess expected registration performance and quantify acceptable image parameters. Spectrally insensitive algorithms will be developed by employing an Automatic Terrain Classifier (ATC). Feature attribute matching techniques will be employed to overcome differences in image scale and orientation. Phase II will extend the techniques to process images with significant perspective distortion and to perform 2D-to-3D image registration. TSC will leverage existing ATC software developed for DARPA, photogrammetry experience gained during urban database development contracts for the FAA, and general classification techniques developed during numerous efforts. In addition to any Government supplied imagery, existing SAR, IFSAR, Landsat and aerial photographic imagery will be employed to support algorithm development and performance evaluation. |

| Title: | Signal Processing and System Concepts to Exploit Passive Signals in Airborne Active ASW Missions |
| Abstract: | Future Airborne ASW tactics will depend heavily upon the use of active sonar and bistatics with a distributed field of sonobuoys as the primary means of initial target detection and localization. However, the bistatic detection and classification problem is compounded by short contact times, evasive target maneuvers, and the ambiguous nature of target echoes and clutter. Recent studies indicate that some target signals are potentially exploitable by passive detection, even in the acoustic and tactical environments of interest for active search. A method of detecting these signals, and a method of incorporating the clues provided by such detections, is desired to augment the information obtained from the processing of the active sonar data. A system level approach to achieving this passive signal detection, and implementing the techniques in an Air ASW active search mission is proposed.The proposed techniques will demonstrate that the passive detection methods are useful, and that they provide added value to current and future active search based Air ASW missions. |

| Title: | Hyperpixel Sensor |
| Abstract: | Technology is still a long way from packaging an electromagnetic sensor as efficiently as the eye of the mammal. This is especially true in the mechanics of focus, iris control, and pointing. However the eye is a good model for the features which should be emulated in a next generation sensor. Electronic and signal processing emulation techniques have already been demonstrated. As higher and higher resolution sensors are implemented an electronically steerable ÇfoveaÇ can be contemplated in a wide field of view optical system. This combined with on and near the focal plane processing could provide a sensor with eye type capabilities. Those include: wide field of view, staring sample rates, image resolution enhancement through saccadic motion and image motion compensation, spatial and temporal pre-filtering, and fovea resolution enhancement in the area of most interest. ISC plans to architect such a sensor in the Phase I program using its Z-technology focal plane architecture and Vector Image Processor technology for signal processing. A novel on focal plane pixel summing (hyperpixel) technique will be used for the majority of the focal plane array in order to reduce output bandwidth, except in an electronically steerable fovea area where high resolution is required. |

| Abstract: | Group 16 Research and Development proposes to research and demonstrate the feasibility of developing new low-latency, high-throughput network interfacing elements that will permit next-generation avionics systems to exploit high-performance computing and communications in an efficient, scalable, portable, and interoperable manner with independence between applications and interconnects. The interfacing elements will consist of a novel hardware interface between the processor/memory bus and gigabit network, and lightweight channel software working with the hardware in support of distributed and parallel applications. The hardware interface will be designed to achieve on the order of processor-memory bandwidth or interconnect throughput, whichever is less, to support a high-performance commercial interconnect standard such as Scalable Coherent Interface, Fibre Channel, or Serial Express, and to support a high-performance processor architecture such as UltraSPARC, PowerPC, or Pentium-II. The software interface will be designed to provide lightweight communications, interoperability, and portability across message-passing and shared-memory, and support distributed and parallel processing mechanisms including CORBA-compatible object request brokering and POSIX-compatible, low-latency multithreading. A new and unique integrated simulation environment will be used to model the processor, network, and software architectures with high fidelity to match performance characteristics in order to achieve optimum throughput, latency, and system cost. |

| Title: | Imaging LADAR System with Ultra High Speed Range Acquisition |
| Abstract: | In the almost three decades since its inception, laser radar has progressed from cumbersome laboratory prototypes to reliable field systems. LADAR systems are currently based upon either a pulsed, time of flight measurement technique or a coherent detection scheme. Time of flight measurements systems are effective but suffer from limited spatial resolution and susceptibility to target camouflaging techniques. The coherent modulation technique offers many advantages including increased signal to noise ratio, simplified light sources and a higher immunity to multi-pulse camouflage methods. To date, the primary limitation to the coherent receiver concept is the availability of high speed, low noise detectors which offer a reasonable range, spatial and gray scale resolution. SMD proposes the development of an imaging LADAR that is capable of operating at 2,000,000 fps, and storing 16 images at 256 x 256 resolution. The detector and source are illuminated to form a coherent imaging LADAR system that measures range by modulation of both the source and intensifier gain. The sensor package can be fitted with a filter system to provide multi-spectral LADAR imagery for diverse applications including standard range measurements, atmospheric constituency information, and direct wind detection. |

| Title: | Weapon System Operator Tactical Operation Aids |
| Abstract: | Develop the combined use of voice commands, tactical decision aids and cueing as a form of Tactical Decision Aids (TDAs) to increase weapon system operator performance in high work-load scenarios. The combined enhancements to a weapon system have the potential to significantly reduce operator workload while increasing the Weapon System Operator's (WSO's) ability to react and proact to potentially hazardous situations. Research is needed to: Determine the basic tactical functions to be employed using the voice recognition system; Determine the best cueing methods and under what circumstances they should be initiated; Determine the TDA's that should be developed and how they should be initiated and modified in real-time; Determine the enhancement of operational effectiveness feasible for mixed cues using new technologies. Seminal research will be continued in the determination of cueing operational effectiveness of the outer to inner ear transfer and the Head Referenced Transfer Function that is critical to the faithful 3-Dimensional (3-D) audio cueing human experience. A Natural Language Speech (NLS) recognition and synthesized speech interface will be matched to suitable tactical operations to demonstrate the effectiveness of this intuitive interface. Message annunciation, situation oratory, decision prompts, alerts and warnings are part of this significant speech supported TDA. Unique to the research is the investigation and utility of using WSO initiated voice commands for tactical software function initiation in conjunction with TDA's and operator cueing for high interest action and in critical situations. A natural language interface that supports human computer dialog for ready identification and remedy of critical situations will benefit from the combination of speech recognition, speech synthesis and 3-D audio technologies. Innovative knowledge management techniques will be used to convert the C2 situation information into decision relevant knowledge. These knowledge management tools are an innovative part of the TDA which can relay "know-how" to the WSO through the spoken dialog interface. |

| Title: | Low Cost, Light Weight Optics for Improved Multi-Function EO Sensor Performance |
| Abstract: | Lighweight, stable, and stiff electro-optical sensor telescopes are required to increase performance and reduce life cycle costs of fixed wing, helicopter, ship, submarine, and man-portable tactical applications. The sensors provide color TV, NIR TV, laser ranging and designation, and MWIR plus LWIR imaging and tracking. The sensors must operate at multiple wavelengths through a common aperture and require wide field-of-view, all reflective, off-axis optics. The limitations in thermal stability, weight-savings and cost that are associated with current aluminum telescopes can be overcome by using carbon fiber reinforced composite material in con-junction with optical replication processes. The goal of this SBIR project is to significantly reduce the life cycle costs of sensors and improve their system performance and usefulness by introducing thermally stable, high stiffness, low density material. This goal will be addressed by designing, developing, manufacturing, and testing sample mirrors and a composite afocal telescope for LRAS3. Our plan is to install the new all-composite telescope in an existing LRAS3 electro-optical sensor, evaluate its performance, and directly compare it to the current diamond-turned aluminum reflective assembly. COI anticipates that the telescope will be considerably more stable thermally, lighter, optically comparable, and cost effective relative to the aluminum version. |

| Title: | Environmentally Adaptable Detector/Classifier |
| Abstract: | Environmentally robust detection and classification aids are critical to the ASW search mission in order to assist in decision making and reduce operator workload. In future multi-static, multi-receiver search missions, the number of alerts is expected to increase dramatically. An operator will simply not have the time to manually analyze and classify all the target and clutter returns without an algorithm to assist him. The goal of this SBIR effort is to develop environmentally robust algorithms that significantly increase detection and the ability to discriminate target returns from clutter, and ultimately reduce the operator workload. Many past efforts have been all-or-nothing ventures. Either the operator does it all by himself, or the algorithm completely replaces him in his effort, or at best has no interaction with him. A major problem with previous automated systems is that when the classifiers are exposed to a new and unknown environment, they suffer a drastic performance degradation. The effort proposed here will capitalize on information extracted in situ from initial insonification of the search area. Techniques are proposed to identify those echo return features which best exploit the current mission operating environment. Operator tools are proposed which keep him in the loop, reduce classification workload, and allow him to process large amounts of detections simultaneously. |

| Title: | Advanced SAR Techniques at VHF (88-108 MHz) for Mine and Unexploded Ordnance Detection |
| Abstract: | Airborne SAR systems currently exist and are used for wide-area surveillance and ground mapping. The majority of deployed systems have frequencies (400 MHz-30 GHz) which, in most cases, cannot penetrate the soil to the depth required for detection of buried mines and unexploded ordnance. Lower frequencies are required for penetration of the ground. However, in the lower parts of the frequency spectrum, the techniques and waveforms currently used to achieve SAR across-track range resolution, such as pulse compression or impulse waveforms, create major sources of wide-band interference to other systems when the radar is transmitting. Conversely, all other emitters operating in these crowded frequency bands cause significant levels of interference to the SAR radar receiver. Amelex proposes to investigate new SAR system components and waveforms to generate an RF signal with sufficiently low frequwency to penetrate the ground and with the ability to achieve the across-track resolution required while reducing the EMI on both transmit and receive. |

| Title: | Wavelet-Based Detection and Classification for Shallow-Water Impulsive-Source Sonar |
| Abstract: | In recent years the anti-submarine-warfare mission of the U. S. Navy has been expanded to include operations against stealthy, diesel-electric submarines operating in near-shore, shallow water regions of the world. Acoustic conditions in such regions are characterized by significant spatial and temporal variability. This variability reduces the performance of traditional sonar detection and classification algorithms. Impulsive-source active sonar systems can provide sufficient acoustic energy to detect these targets, but also produce significant clutter in a shallow--water environment. Detection of too many false targets can quickly overload sonar operators, so that true enemy targets are not detected and properly classified. Our proposed research will use a combination of wavelet and nonparametric bootstrap methods to achieve improved performance for detection and classification. Bootstrap methods allow one to adaptively estimate the underlying probability distribution of interference in the non--Gaussian colored-noise environment typical of shallow-water active sonar, and to set detection thresholds to maintain a desired false alarm rate. Subsequent target classification will be performed using wavelet representations of the sonar echoes, taking advantage of the time--frequency structure of targets and clutter. These representations may be combined with existing discriminant analysis methods. This work will demonstrate the feasibility of these techniques for sonar target detection and guide our phase II development of improved methods for detecting and classifying targets in the presence of clutter. |

| Abstract: | The "Low-cost, Micromachined Adaptive Optics Systems" SBIR program provides a path for bringing an innovative new technology to enhance tactical electro-optical systems such as laser designators, ladar, and infrared countermeasures. Schafer Corporation recently completed analyses for the Naval Air Warfare Center Aircraft Division that show the benefits of low-cost, low-weight, low-power-consumption micro-electrical-mechanical (MEM) adaptive optics in supporting Navy missions. Under the proposed effort, Schafer will design a lightweight, low-cost closed loop adaptive optics system which will have an integrated wavefront sensor, signal processor, and deformable mirror. MEM adaptive optics have weight and power characteristics that are two orders-of-magnitude less than conventional discrete actuator deformable mirrors. We will use the patented comb-drive MEM deformable mirror technology developed by our team member, SY Technology, Inc. Although some of the missions that were studied in the NAVAIR program will be considered in this SBIR, our emphasis here will be on MEM adaptive optics system design and assessment of the wavefront beacon concept, rather than a mission performance analysis. Schafer Corporation intends to have the technology developed and fully tested in time to impact the design of 21st Century tactical EO systems as well as supporting commercial applications in medicine, communications, and astronomy. |

| Title: | Passive Target Velocity Measurement System |
| Abstract: | This project characterizes and designs a sensor able to measure passive airglow reflections in a wide-field to detect anomalous velocity enhancements - the "PAR-WAVE" sensor. These velocity enhancements are caused by reflections of airglow emission features from fast moving objects. To achieve the required fast spectral integration, durability, and background rejection, the system features solid-state Fabry-Perot etalons using electronically tunable liquid crystals to achieve spectral line profile scanning. The feasibility of the proposed three-etalon system is evaluated by testing the transmission and spectral resolution capabilities of existing liquid crystal etalons, and by measurements of candidate airglow features using a conventional air-gap Fabry-Perot interferometer. The Phase I project delivers an optical and mechanical design balancing the field-of-view, spectral resolution, and sensitivity parameters into a device best suited for covert velocity detection in a cluttered atmospheric or littoral environment. The mechanical design permits selection of 2 - 4 spectral features depending on the field conditions, and permits two or three etalon operation optimizing throughput to daytime or nighttime background conditions. Laboratory and field-testing of extant, high spectral resolution liquid crystal etalons is a central feature of the Phase I initiative, permitting expeditious fabrication of a PAR-WAVE prototype in Phase II. |

| Abstract: | An artful technical approach for achieving reliable >32 Mbps wireless transfer of integrated data, voice and video information is proposed. The technical approach utilizes 48 octet fast pack transport similar to as in ATM. The proposed wireless system provides network connectivity using legacy network interface standards (i.e. Ethernet, T1/E1, etc.) as well as through emerging network interface standards (i.e. ATM, SDH, etc.). To achieve high data rates, an artful solution to multipath propagation and its associated intersymbol interference is proposed. Novel waveform shaping techniques are utilized to gain spectral efficiency and highly linear modulators are used to prevent spectral blooming. Artful technical approaches are proposed to increase battery life (for a given throughput) by one or two orders of magnitude compared to presently available cellular telephones or 802.11 wireless LAN products. The use of a deterministic media access controller ensures low-latency (6 milliseconds) within the system and guarantees quality of service for the users of the system. |

| Abstract: | For safety of operation, Unmanned Aerial Vehicle personnel require a Situation Display that shows the position of the UAV and other aircraft in the area. For field operations the system must be manportable. The cost of the system must be affordable for this purpose. I-Comm, in cooperation with its partner Allied Signal Aerospace, has outlined a comprehensive Phase I project that will develop a Situation Display that is suitable for use by UAV operators in a field environment. The team has selected an existing interrogator/processor for the system and has identified a number of small commercial phased array antennas that may be adapted to meet the operational requirements. The major part of this effort addresses antenna selection, evaluation, and adaptation to meet the required operational capabilities and interface to the existing interrogator/processor. Additionally, modifications to existing software for display of the desired information on a laptop PC will be determined. The system configuration will allow augmentation for enhanced future capabilities. |

| Title: | Repair Technique for Electroplated Surfaces |
| Abstract: | A newly demonstrated technology (patent pending) provides a unique solution to repair of electroplated and other surfaces. The repair process permits the use of a wide variety of repair metals/alloys, is environmentally friendly, requires little/no cleaning of the breached surface, and can be applied in the depot or field (no special environment required) over many electroplate or other material surfaces. This replacement for electroplating is called Laser Induced Surface Improvement (LISI). Two years of laboratory development/testing have fully demonstrated its ability to produce a corrosion-resistant surface free from porosity and cracks. LISI can process hard-to-reach surfaces with laser energy transmitted via fiber-optic cable. The process can be used for touch-up of small areas or can process up to 50 sq. ft./hour with a 3 kw YAG laser. Further, the molecular bond of the repaired surface alloy resists all attempts at delamination or peeling and can accommodate a wide range of temperatures (coefficients of expansion). The result is a permanent thin layer of protective material (10 to 1000 microns with depth determined by controlled operating parameters). Phase I will demonstrate the applicability of several repair alloy formulations, investigate the integrity of the repair, and examine any effluents from the process. |

This conversion system will be designed to include the decision "tree" for identifying the feasibility of cost saving factors, the structure for locating existing media elements, and the possibility of the whole conversion system being web-based. This research addresses conversion of existing training assets into a dual use scenario through the use of a decision model that leads to a conclusion concerning conversion potential and availability of the asset. This will be accomplished through determining feasibility of implementing cost cutting strategies (e.g., a reuse strategy of graphics and other critical media elements to cut the costs of CBT development). A strategy for storage and retrieval of media elements along with identification of requirements for establishing the conversion system on the web. A proof of concept for applying the conversion system to development as well as revision of existing courseware will be provided. |

| Abstract: | This proposal addresses development of a distributed image oriented storage and indexing architecture for building content searchable image databases (containing test, graphics, images, and digitize video). This is particularly difficult because computer vision has yet to solve the shape recognition problem which encompasses both text type and object type entities. Also, since substantial computation must be done to match image contents, substantial responsibility for the process must be delegated to the image archival engine (or in fact engines, because balancing data stored with computational elements is very important in this application as compared to more traditional text-oriented indexing and searching). In Cybernet's Phase I effort we will prototype a single node of the search engine and associated browser. Later we will scale the prototype product up for full scale Navy use. |

It is believed that through the use of a component model, a distributed object model, a portable programming language, a rule-based knowledge-base, and simulation and scenario based Intelligent Tutoring System (ITS) authoring utilities, such an environment can be realized. A well designed component model would make an extensible visual development environment possible. Portability can be achieved through the use of a highly portable programming language.

| Title: | Eye Tracker Using Bug Eye Orientation Sensor and Fuzzy Metrology |
| Abstract: | Physical Optics Corporation (POC) proposes a new and innovative method of eye tracking, incorporating an Inverse Bug Eye Orientation System (IBEOS) in conjunction with fuzzy metrology to determine the orientation of an observer's eye. This eye tracking system can be applied directly to a virtual reality training system to determine the image resolution requirement so as to adjust the VR processing speed. In the proposed system, an invisible IR point source created by an optical fiber tip in front of the observer's eye creates a virtual image through Fresnel reflection from the cornea. Eye movement causes the virtual image of the point source to move. The IBEOS simply and rapidly determines the direction of the point virtual image of the light, and hence the orientation of the eye. The system is optical, and therefore immune to EMI and RFI. The BIEOS system is redundant, robust, and easily calibrated, so that it requires no operator training. The use of fuzzy metrology minimizes the influence of stray ambient light. The system can be installed in most environments (including vehicles) without modification. |

| Title: | Aluminum-Nitride Infrared Window Materials for High Heat Load Applications |
| Abstract: | Feasibility of fabricating IR window materials from aluminum nitride (AlN) will be demonstrated. Aluminum nitride windows are sought as replacements for sapphire windows on high speed seeker missiles because of their higher thermal shock resistance. Our approach is to consolidate high-purity ultrafine powders of AlN to obtain a nanocrystalline window. Small grain size is expected to minimize IR scattering, and preliminary data suggest this is the case. Theoretical estimates show that a grain size of 200 nm should yield high thermal conductivity and IR transparency. A novel aspect of this work is a flame synthesis process for producing ultrafine AlN powders encapsulated in a removable coating material to ensure that they retain their purity until consolidation. This sodium/halide flame and encapsulation technology is easily scaleable and the powders produced are unagglomerated and low in oxygen. We will also employ a novel consolidation process that sequentially removes the encapsulation material (sodium chloride) prior to vacuum hot pressing so that AlN powders are never directly exposed to atmosphere. For this program, ultrafine AlN powders will be synthesized and consolidated into 1 mm thick disks. Both powder and compacts will be characterized for IR transmission, elemental composition and crystal phases to determine the feasibility of using such materials for infrared transparent windows. |

| Title: | Electrically Conductive Hard Coatings for Aircraft and Missile Domes |
| Abstract: | Current IR systems are extremely susceptible to electromagnetic and radio frequency interference (EM/RFI) because they possess large apertures that present ideal front-door entry paths for EM radiation. Significant amounts of EM radiation (400 MHz - 18 GHz) can penetrate and couple to the IR sensor and supporting electronics, which leads to a substantial degradation in systems performance. EMI protection is critical to the survivability of the IR system and the system host (e.g., aircraft, satellite). Sienna Technologies, Inc., will investigate electrically conductive ceramics as erosion resistant EMI/RFI protective coatings for IR windows and radomes. We will deposit selected materials as continous film coatings by RF sputtering and study their shielding capability and IR optical transparency. Several compositions with different stoichiometries will be sputtered on window materials and heat treated. Resulting microstructures and sheet resistivities, optical transmission, and erosion resistance will be evaluated as a function of the composition and heat-treatment parameters. Deposition processes will be optimized to prepare test windows. Prepared windows will be tested for EM attenuation, IR transmission, and erosion resistance. |

Further, the rapid pace of their development and the evolution of various UCAV applications stress the need for expeditious optimization of air-to-air and surface attack tactical options in realistic combat scenarios using high-fidelity yet low-cost simulators. Advances in high-speed computer systems allow realistic simulation and assessment of many aspects of UCAV system, ranging from flight dynamics, ingress/egress profiles, sensor effectiveness, weapon tactics, and multi-vehicle coordination schemes. Furthermore, the maturity in personal computer (PC) systems makes them ideal for preliminary evaluations of UCAV systems previously addressable only by complex and expensive dome simulators. The proposed effort will further expand the application of offeror's current six-degree of freedom high-fidelity simulation capabilities on the PC's and provide Navy the unique capability to cost-effectively simulate and test UCAV air-to-air and surface attack maneuvering tactics and control paradigms in realistic combat scenarios. This submittal proposes to use a PC-based commercial off-the-shelf simulation environment, D-Six, developed under Air Force SBIR by the offeror, as the basis for the development of the UCAV simulation platform. The system will be leveraged by the many embedded development, analysis and networking features, significantly reducing the time and cost required for research, testing, demonstration and evolution of a viable multi-vehicle simulation platform. |

| Title: | Accelerometer-Based Multi-Sensor INS |
| Abstract: | Inertial navigation systems for airborne applications use three axis accelerometers and three axis rate gyros, and in many cases additional inputs using GPS and other sensors. The objective of the proposed work is to replace the expensive rate gyros with rate estimates based on multiple low-cost accelerometers. The error characteristics of the accelerometers, chiefly the bias stability and broadband noise, limit the accuracy and hence the application of the resulting accelerometer-based multi-sensor inertial navigation systems (AMS-INS). The technical challenges are first to predict the fundamental limitations using detailed error analysis, and then to design the hardware and embedded software algorithms needed to maximize the available performance. The proposed algorithms include robust statistical estimation, online identification of bias error terms using Kalman filtering or neural networks, and self-initialization of the rate estimates using measurements of centripetal acceleration. The Phase I effort will include a simulation test bed for AMS-INS development, single axis measurements, and both analytical and Monte Carlo error analyses. A hardware and real-time software design |
