| Title: | Cased Telescoped Ammunition Smart Seal Development |
| Abstract: | Cased Telescoped Ammunition (CTA) has the potential to allow use of lighter ammunition-feed swing chambers, and more efficient ammunition storage, which will move the Army toward the lighter vehicles required by the Future Combat Systems (FCS) program. Technical obstacles have blocked the widespread application of CTA, particularly the sealing of propellant gases at the fore and aft of the cartridge during firing. MSI will extrapolate its experience in bioengineering applications with Nitinol shape memory alloys and other smart materials, and in design of seals for turbomachinery including aircraft gas turbine engines, using advanced computer-aided design analytical tools. In order to provide a tool for designing rings or sleeves which result in enhanced and reliable sealing, the coupled engineering problem will be attacked calculating the turbulent viscous leakage flow, acoustics, transient heat transfer, contact elasticity, and hyper-elastic (in the case of Nitinol) response. Physical properties required for the selected material (e.g. strain rate sensitivity of elastic modulus) will be verified by special testing by the material supplier. Three different conceptual prototypes will be manufactured to confirm their ability to take on conforming shapes, under elastic and/ or thermal loading, to enforce forward and aft sealing in a prototype 105 mm cartridge. Smart materials, particularly shape memory alloys, are applicable in many military and civilian applications involving sealing, gripping, deployment of large volume/ weight devices from initially compact storage containers, and actuation. Few applications have been attempted involving the sudden temperature changes or sonic rates of strain experienced by gun cartridges. The knowledge base accumulated to succeed in the CTA application will allow MSI to offer designs for other applications in aerospace, automotive, and industrial actuation and sealing in situations where temperature, pressure, or loading are extreme or may rapidly change, such as in plastic injection molding, and in gas turbines. |

| Title: | Enhanced Range Using Adaptive Flow Control Structures For FCS Multi-Role Armament Munitions |
| Abstract: | To meet the goals of the Objective Force, the Army has initiated the development of Multi-Role Armament Munitions for Future Combat System (FCS). Current smart cargo projectiles and hit-to-kill munitions use conventional control surfaces like fins and canards for stability and control, which limit their range and maneuverability. Also, the volume required by the current control actuation system (CAS) limits the munitions payload capacity and the overall mission performance. Orbital Research proposes to develop an Aerodynamic Flight Control System (AFCS) based on two adaptive flow control structures: (1) Deployable Conformable Wings (DCWs) and (2) MEMS based Deployable Flow Effectors (DFEs). The control structures will be used in conjunction with an intelligent controller to provide a cost, power, and volume efficient flight control and lift enhancement system which can be readily integrated into any Army's FCS multi-role armament munitions. The AFCS will be able to maximize body parameters like lift for enhanced range, withstand harsh launch and environmental conditions (high pressure and temperatures, shocks, acoustic noise, etc.), and provide high maneuverability and control for least amount of power consumed from the vehicle. Additionally, the overall costs of flight control system per round will be kept to a minimum level. The proposed Aerodynamic Flight Control System (AFCS) will provide extended range and enhanced control and maneuverability to increase the lethality and accuracy of hit-to-kill and/or shoot-to-kill munitions. Military benefits will include providing Future Combat System (FCS) with a cost, power, and volume efficient control system that will enable rapid lethal response capability against a wide spectrum of threats. |

| Title: | Innovative Conformal Power Sources for Advanced Smart Munitions |
| Abstract: | The objective of this project is to study the feasibility of a number of novel methods and concepts for conformable power sources that can be integrated into the structure of the projectile with minimal or no loss of the intended functionality of the structure. The structurally integrated power sources are load bearing. As the result, all or a significant portion of the space required to house the power source and the aforementioned components can be saved. In addition, the power sources and their related components are better protected against high acceleration loads, vibration, impact loading, repeated loading and acceleration and deceleration cycles that can be experienced during transportation and loading operations, i.e., are highly survivable. Such power sources are also safer, have longer shelf life, and are more reliable. The conformal and structurally integrated power sources have numerous other military and commercial applications. Such power sources are ideal for use in different types of missiles and rockets, in satellites and in all different types of commercial disposable electronic devices such as flash lights, cameras, and the like. |

| Title: | Active Projectile Course Correction System (APCC) |
| Abstract: | The main goal of this Phase I project is to demonstrate the feasibility of an Active Projectile Course Correction System (APCC) for a Light Fighter Lethality (LFL) Seeker High Explosive Projectile. An APCC system consists of a control and guidance algorithm for a projectile seeking an identified target through an infrared seeker. For the success of this project, there are three major areas where focus is required. First, there is a need for development of a reliable trajectory estimation algorithm based on sensed data. Second, there is a need to develop an on-board reliable feedback mechanism for course correction of the projectile. Third, there is need for development of a real time discrete control system for trajectory course correction. In this proposal, the key innovation is the control and guidance of a projectile trajectory for tracking a moving target using an on-board seeker. Some of the expected outcome of this project would be as follows. Real time ballistic projectile trajectory estimation using Data Fusion and Kalman Filtering. Synchronization of the image seeking activity using a flagging system with proper projectile orientation. Optimal desired trajectory computation using inverse dynamics. Target tracking using discrete controls for navigation and guidance. PACC will result in the development of some generic algorithms such as data fusion and Kalman filtering for enhancing the reliability of sensor data., discrete control algorithm for navigation and guidance of dynamic systems, trajectory estimation and optimization of dynamic systems. Some of these algorithms will be reusable in various other engineering applications. The technology developed under this project can utilized for other weapon systems of different sizes. For example, the results of this effort can be applied to the Medium Cannon Caliber Guided Projectile Program, the Objective Crew Served Weapon and the Objective Individual Combat Weapon. Immediate beneficiaries of PACC technology will be DOD. This technology can be applied to bomblets and sub-munitions for other services weapon systems. In the commercial area some of the technology developed for PACC can be used to build safety device for mid-air collision prevention of small aircraft. |

| Title: | Miniaturizable INS/GPS/IR Sensor-based Navigation System for Small Caliber Projectiles |
| Abstract: | The Light Fighter Lethality (LFL) seeker projectile is a small caliber weapon with INS and imaging sensor. Its size, weight and short flight time places restrictions on guidance and control of a different dimension than normally seen in guided weapons. This project aims at developing navigation filter architectures, guidance laws and integration concepts that would enable LFL seeker projectile hardware development. Loosely coupled INS, GPS and IR sensor-based systems are proposed to maximize use of existing miniaturization technology. The main Phase I tasks are to (1) obtain LFL projectile simulation models, (2) develop INS/GPS/IR-sensor based navigation and control systems, and (3) evaluate system performance. Several control laws including classical proportional navigation and modern robust control will be investigated. Phase I option period will be used to identify hardware issues and promising technologies that may permit a prototype demonstration in Phase II. Scientific Systems Company, Inc will be supported by Draper Laboratory in all phases of the project. Integration of GPS, INS, and passive imaging sensors is essential for intelligent autonomy. The proposed work has direct applications in formation flying, distributed spacecraft, telerobotics, intelligent automobiles, rendezvous and docking operations, cinematography. |

| Title: | High Brightness Beam-Coupler for High Power Diode Lasers |
| Abstract: | High brightness lasers have been identified as a means of producing acceptably short and reliable munition ignition times in large caliber guns. For practical purposes, these lasers must be compact, low-cost, efficient and robust to withstand the harsh shock environment. High power multiple emitter diode bars can meet these criteria, but poor beam quality (typical M2>1000 from a single 50W bar) and low spatial coherence are incompatible with the high brightness requirement for ignition. CTI proposes a novel, compact and efficient active beam-combining architecture, capable of dramatically enhancing the combined brightness of multiple diode bars to generate near diffraction-limited output. The beam-coupler has excellent heat dissipation, and a proprietary architecture that virtually eliminates thermo-optic beam distortions. In one possible configuration, up to twelve 50W diode bars are butt-coupled into, and combined in, a single 70mm long lightweight module. Modeling, anchored by our recent proof-of-concept demonstrations indicates a brightness enhancement of more than 300x with respect to the direct diode output. Modules may be stacked to scale power to multi-kW levels, as required, without loss of brightness. CTI's proven ability to design and engineer rugged and compact electro-optic systems for demanding environments will ensure a successful overall development program. Anticipated applications include (1) ignition systems for munitions and explosives, (2) high power laser for aerospace-platform missile defense, (3) low cost, active LADAR sensors for industrial and military markets (4) cost-effective laser sources for materials processing, printing, and medical applications. Waveguide amplifiers have the potential commercial appeal in the high power laser market that fiber lasers have in the low power market. |

| Title: | Innovative High Energy Laser |
| Abstract: | Very high power can be obtained by combining a large number of diode laser bars, but unfortunately the combined output consists of a very low-brightness beam with very large beam divergence, therefore, it is unsuitable for igniting large caliber guns. PC Photonics is proposing a diode-pumped multicore fiber laser array, which is capable of delivering very high power in a high-brightness beam emitting from an aperture of ~30 microns, in which the power density is sufficient to ignite large caliber guns. By phase-locking 7 Yb-doped single-mode fiber lasers in a common cladding, PC Photonics has obtained a high-brightness laser beam by clad-pumping this fiber laser array with a multimode diode laser. The optical to optical conversion efficiency is 87 %. Under Phase I, PC Photonics will use the highest professional standard to design a high energy laser, which will meet Army Crusader's requirements with a great deal of confidence. Under Phase I-Option, preliminary experiments will be performed to demonstrate a unique technique for efficient pumping of the double-clad fiber at very high power level. High power diode-pumped multicore fiber lasers can be very competitive in the market place as compared to high power diode-pumped solid-state lasers and CO2 lasers presently employed by automobile, aerospace and heavy manufacturing industries for precision welding, cutting and drilling of metallic and composite materials. Other applications include laser printing, bar coding, inspection, dental and medical surgery. |

| Title: | Low Cost Composite Peizoelectric Spring for Acoustic Applications |
| Abstract: | This program proposes to develop a power source capable of producing a high-output directional transmission of acoustic energy, using piezoelectric spring-shaped drivers produced using ACR's Fibrous Monolith (FM) technology. These "springs" will consist of a piezo-electric core surrounded by a conductive metal outer layer, and will be configured to provide the desired acoustic output signal while giving consideration to device size, weight and cost. The use of FM processing technology will make it possible to rapidly provide any one of a virtually infinite number of final spring configurations. This design will also provide a method to "pole" the piezoelectric using the outer metal shell to provide both the necessary heat and electric field. The springs can be fabricated from a variety of materials, including those that provide significant high temperature resistance (i.e. >1000 øC). In addition to the above-mentioned acoustic application, these springs also have potential application as load sensors and piezoelectric actuators, especially where resistance to harsh environments is critical. This has a verity of commercial applications including load sensors, actuators and acoustic sources for stereo speakers. |

| Title: | Power Generation/Recovery Systems |
| Abstract: | Modern soldiers are increasingly burdened with state-of-the-art electronic components that require batteries for operation. The added weight of these systems can exceed 80 pounds, excluding provisions required for prolonged equipment operation. Currently, sustained field operations require personnel to carry additional batteries or for logistic planners to ensure remote drops. Without this replenishment, even the most technologically advanced gadget becomes worthless and a mere nuisance for the soldier in the field. Replenishment becomes a non-issue for scenarios where motorized vehicles are accessible but for remote and /or small teams, guaranteeing a steady supply of batteries for these devices becomes a serious logistics problem. Luna Innovations proposes to ease this logistics problem with the development of a power generation device that captures the excess energy from small caliber gunfire. This device will utilize a very small portion of the excess kinetic energy generated during the firing of the weapon, will have no significant impact on the mechanical reliability or performance and will integrate easily into host platforms. The proposed device to be developed and integrated is a miniature linear alternator. The linear alternator approach provides the highest possible energy producing capability for a given size and can be integrated into existing sub-assemblies. The technologies and methods developed in this program can be applied to numerous military weapon platforms. In addition, research and development from this program will aid in the finding new ways of satisfying the increasing power demands for today's electronic world. Luna's previous success has resulted in two spin-off companies dedicated to the production of state-of-the-art sensing systems. |

| Title: | Reconfigurable RF/Wireless Full-Duplex Syntonic Data Communication System |
| Abstract: | Next generation of advanced weapon systems and platforms, such as the Future Combat System Multi-role Cannon and Munitions Suite require low-cost embedded wireless sensors and actuators with data communication / command capabilities. With the growing need of sensors the powering and communication with them becomes a critical factor. Applications often require such devices to be completely embedded with no physical connection to the outside world. It is proposed that a wireless sensor system be developed that is a highly integrated data communication system design that combines embedded MEMS sensor technology with low power signal processing microwave RF MEMS techniques. The undertaking is focused on the development of the required system components. The expected result is an affordable flexible and complete power-aware data communications design that may be embedded within wireless munitions sensors. The DoD requirement for small form factor embedded wireless sensors for long term diagonostic testing and data loggging is highly supplemented by comparable applications in the commercial marketplace. |

| Title: | Real-Time Gun Barrel Condition Monitoring for the Future Combat System |
| Abstract: | FBS, Inc. proposes to demonstrate the feasibility of a real time gun barrel condition monitoring system using ultrasonic guided wave technology. Guided wave technology is especially suited to the cylindrical and plated (layered) geometry of a gun barrel. Under user control, guided waves can be channeled to specific portions of a gun barrel's volume and used to detect defects in those volume portions. This capability is key as crack arrays, occurring in gun barrels cause serious decreases in barrel fatigue and/or erosion life. Barrel impacts with external objects such as trees, rocks, and etc. can also manifest their damage in these volumes. FBS, Inc. will use its guided wave modeling capability and field experience knowledge base to isolate those aspects of guided wave technology most appropriate to gun barrel condition monitoring. FBS, Inc. will design a gun barrel condition monitoring system, build a prototype system, and demonstrate it to the U.S. Army. The research conducted here will advance inspection technology in many areas including tubes, plates, composite and multi-layered structures, etc. This project's use of modeling concepts, transducer design, signal processing, system construction, and control software will move the technology forward. Utilization of real time monitoring for tubular structures is highly desired throughout many industries (e.g., gas and oil, chemical, electric power generation, etc.). The steps taken here will advance the state of the art in guided wave inspection significantly. |

| Title: | Real-Time Gun Barrel Condition Monitoring for the Future Combat System |
| Abstract: | Recent advances in ultrasonic array technology and the analysis of the associated waves for plate-wave propagation have enabled novel practical applications. In this Phase I SBIR proposal, we will demonstrate that helical ultrasound tomography (HUT) can be applied to assess gun barrel health for large weapons systems. Two transducer array belts wrapped around the gun barrel will launch and receive the complex wave modes that propagate in the gun barrel. Since ultrasonic waves are sensitive to cracks, thinning and distortion, it is anticipated that the information in the waves will enable a health assessment of the gun barrel itself. The measurement can be done in near real-time, and a portable device for field use is feasible. The Phase I effort will investigate the wave propagation and model the array design needed to extract diagnostic information associated with gun barrel damage. Tests will be conducted on representative samples and waveform analysis will be explored to correctly model the propagation parameters. Increasingly realistic samples will be tested to advance the model development and array design. The Phase I effort will provide sufficient information to achieve a preliminary design for an array system for real gun barrels. The application of this technology to gun barrels will also further the potential commercialization of the technique to monitor high-pressure manufacturing process pipes, power plant pipes and other valued advances in the commercial sector. |

| Title: | MEMS INS for Pointing and Aiming Control of Large Caliber Indirect Fire Artillery |
| Abstract: | The objective of this Phase I project is to design a MEMS based Inertial Navigation System (INS) for pointing and aiming control of large caliber indirect fire artillery using the AGNC-developed microelectromechanical system (MEMS) IMU. In Phase I, first, the hardware and software design of the MEMS based Inertial Navigation System is proposed and investigated. Then, the multiple IMU placement and processing algorithms are designed and investigated. Next, an AGNC-developed MEMS testing and calibration system is used for design evaluation. Through system modeling and simulation, we investigate the feasibility and performance of the MEMS based Inertial Navigation System. Finally, an accuracy evaluation of the MEMS based Inertial Navigation System is performed by way of a hardware-in-the-loop simulation. The proposed navigation system can provide attitude and heading (azimuth), angular rate of attitude and heading of the artillery barrel for the control and aiming system. Integrated with the data from a GPS receiver it provides an accurate position of the artillery. DSP and ASIC based system hardware design makes it easy to provide military standard electrical interfaces (such as MIL-STD-1553B) to the command and control system. Because of its small size, low cost, and light weight, the MEMS based Inertial Navigation System has wide applications in navigation, control, and guidance. Examples of application areas include: land vehicle navigators, airborne vehicles, microrovers, micro tracking mechanisms, space robots, , micro UAVs, and miniature underwater vehicles. |

| Title: | Innovative Inertial Navigation System for Large Caliber Indirect Fire Artillery |
| Abstract: | The proposed research effort is to complete a (concept) design for a durable, lightweight, compact, MEMS inertial measurement unit (IMU) for use with mortars and lightweight artillery. The systems in use at this time are too heavy and too large, which makes them very difficult to adapt to this (extremely high) shock environment (potentially > 15000 G's). The proposed design will not only use this breakthgrough in component technology (i.e. MEMS gyros/accelerometers), but through an innovative redundancy management approach, will provide unequalled performance with this type of hardware. The proposed system will provide pointing accuracy better than 1 mil-radian in bearing, and better than 0.25 mil-radian in elevation, over the full military environment, and the full range of requirements for latitude initialization (i.e. <5 minutes up to 65 degrees). The system design will use MEMS gyros that are expected to be in production in less than a year, and therefore this systems approach requires MEMS gyros with bias stability no better than 1 degree/hour. In order to insure that the concept is sound and that a successful prototype fabrication can be completed in Phase 2, the design concept will be proven through computer simulations in Phase 1. The benefit of the design/development of this system is the increased durability/reliability of the aiming and pointing systems for mortar/light artillery. Another benefit is that through the use of MEMS sensors, an extremely lightweight/compact inertial measurement unit (IMU) will be developed. This IMU will also provide unequalled accuracy, and because of its size has potential for application as a navigator for the dismounted soldier The commercial applications for compact, low-cost inertial systems are quite extensive and include supplementing GPS data for General Aviation, railroads, and cars and trucks. In all cases, providing more releable position information will improve transportation safety. |

| Title: | Artillery Orientation via Distributed MEMS Inertial Sensing |
| Abstract: | Determining the precise position, bearing and inclination of field artillery is essential for accurate fire. The rapid pace of modern warfare and the increasing efficiency of modern counterbattery methods dictates regular movement of artillery, obviating conventional survey techniques and placing increasing emphasis on the use of internal inertial navigation systems (INS) and of GPS. Present INS systems are vulnerable to shock, and are bulky and limited in accuracy. Physical Optics Corporation proposes to develop a novel distributed reference inertial artillery direction (DRIAD) system consisting of a distributed redundant network of MEMS inertial sensors coupled with carrier differential GPS receivers, which sense the movement and rotation of the artillery. This information is processed with data from existing sources to optimally estimate the position, bearing, and orientation of the artillery. A combination of Kalman and spatial operator algebra methods are employed for optimal fusion and tracking of the artillery. An optional detached inertial sensor will enable the system to recover rapidly from recoil transients. In Phase I, MEMS components will be selected and integrated into a preliminary sensor node design with COTS Carrier Differential GPS modules, and evaluated with preliminary data fusion algorithms. DRIADs in Army vehicles and UGVs will provide extremely precise information on the position and more importantly the orientation of vehicles and pointing devices, a particular boon to forward observers. The combination of rugged construction, precision, and greatly improved GPS reception in marginal areas will prove equally desirable to the automobile industry. |

| Title: | Two-dimensional detector arrays for hyperspectral x-ray imaging |
| Abstract: | Direct-conversion, position-sensitive x-ray detectors are needed in many important technologies such as medical and industrial imaging, nondestructive inspection (NDI) and evaluation (NDE), munitions monitoring, and baggage scanning. Advanced x-ray imaging techniques can register both shape and spectral information by measuring the attenuation of multi-energetic x-rays through the imaged specimen. The density and composition data thus acquired can enable machine recognition of materials, a capability that would be useful for several military and industrial applications. Cadmium Zinc Telluride (CZT) has emerged as the detector material of choice for hyperspectral imaging because it works at room temperature with excellent energy resolution and has a large atomic number (Z), which is essential for high-sensitivity detection of x-rays. High count rate uniformity and maxima of two million or more counts per pixel per second have recently been achieved in CZT using a new linear array design and a custom readout system for ultra-fast hyperspectral line scanning. Further innovation building upon these developments would be desirable, in particular by designing and fabricating a high-throughput hyperspectral imaging system operating in the alternative staring-array imaging mode which would be useful in static as well as conveyor-belt type inspection applications. A very concrete need presently exists for such a system in the manufacture of munitions, specifically in inspection and process control operations which cannot be adequately monitored using current technologies. In response to this, we propose to develop a new x-ray radiographic system consisting of a monolithic two-dimensional, submillimeter resolution pixilated array CZT detector and the corresponding custom readout ASIC (Application Specific Integrated Circuit) and support electronics, which would have multiple x-ray energy imaging and high counting rate capability. The result of the proposed work will be a large, pixilated high-throughput, high-accuracy room-temperature and polarization free hyperspectral 2D x-ray imaging detector system with a custom made monolithic readout electronics chip to handle large amounts of data in real time. It will be able to perform hyperspectral, staring-array imaging in milliseconds using high flux output x-ray generators. This detector has many application capabilities for both the military and commercial sectors, such as immediate discernment of material composition for defects and anomalies at production rates in all kinds of products including propellants and explosives, as well as identifying material in security screening applications and medical imaging such as fast response bone densitometry. DoD applications include all standard x-ray and gamma ray inspection techniques at high speeds with hyperspectral imaging capability which is just evolving. For example, some of the applications are: NDI of munitions, Compton detectors for detection and monitoring of radioactive material, inspection of containers, and contraband detection. CdZnTe detector can be especially useful in battlefields due to their compact nature and room temperature operation especially for radioactivity detection and imaging. Non-DoD applications are even more extensive given the wider variety of objects requiring inspection in many different types of industrial situations. Our work will give special attention to the munitions inspection application which has specific and critical process control needs. |

| Abstract: | Morgan Research proposes a Phase I SBIR effort to develop an integrated MEMS sensor suite suitable for munition and missile health monitoring systems. This suite will include a three-axis accelerometer, a three-axis no-power shock sensor, a humidity sensor, and a temperature sensor. These sensors will be fabricated in a robust silicon-on-insulator (SOI)-based fabrication technology, and be modifications of devices already in existence. The Phase I effort is designed to perform all of the analysis and design required to being fabrication. A successful Phase I will lead to a Phase II in which prototype devices are fabricated and characterized in harsh environments. The proposed integrated sensor suite has application to a wide variety of military systems, including THAAD, Patriot, TOW, and rotary- and fixed-wing aircraft. There are also applications in the commercial sector health monitoring and general environmental sensing in automobiles, boats, and other expensive assets that require periodic maintenance. Furthermore, the device, if small enough, could find potential markets in the transport of food and other items sensitive to environmental conditions. |

| Abstract: | The objective of this SBIR proposal is to design and develop a low cost, micro- electromechanical systems (MEMS), multi-sensor "suite" consisting of 3-axis shock, temperature and humidity sensors, all operating on a single microchip. The desired performance characteristics being: temperature: -50 to 165 degrees F, humidity: 10-95% RH (+/- 6%), 3-axis shock: +/- 500 g's (+/-5%). Work will concentrate on trying to answer the questions of: what are the optimum designs for each sensor type with an emphasis on device integration, and what packaging solutions/configuration will best allow for integration and sensor function while minimizing final unit power and cost. Specifically, one system configuration has been proposed that uses combined optical and mechanical MEMS sensing techniques, which allows for the associated packaging to satisfy each sensor type's unique packaging requirements. Work tasks will include studying design, packaging, power minimization, relative merits of various fabrication processes, and analytical and numerical modeling. The work will be performed through a partnership between Sporian Microsystems and LMTS-Eagan that will take advantage of the two companies combined considerable knowledge base in MEMS design, fabrication, integration, subsystem design, and packaging. To date, the Army has not had a low cost device that could track the complete environmental exposure history of the munitions. Therefore one of the drivers for developing this technology is the need to know the environmental conditions associated with storage, transportation, and field deployment. This is a critical precursor to determining overall munition "health" status. But in addition to this application a low cost, low power environmental sensing/monitoring device would be highly useful in a wider range of commercial applications involving long and short term storage of sensitive equipment, manufacturing process control, status monitoring in automotive applications, food/perishables health monitoring, or HVAC systems. |

| Title: | Single Chip, Three Parameter MEMS Sensor Suite |
| Abstract: | An innovative silicon-based MEMS multi-parameter sensing device is proposed for detection of environmental conditions encountered during weapons storage. The device has the capability to monitor up to 500 g shock in each of three axes, temperature -50 to +165 F (-46øC to +74øC), and humidity from 10% to 95%. The entire device could be contained in a standard surface mount package, cost less than $6.00 in quantity, and consume approximately 10 microWatt of power in typical applications. The entire suite of sensor structures can be fabricated with conventional MEMS processing technology now available at foundries. Device characteristics are entirely dependent on the thickness and geometries of thin films. This makes the sensor suite easily tailored to a wide variety of applications other than DoD's needs. Wilcoxon Research, as one of the nation's leading accelerometer manufacturers, has the capability to design and test the finished device and commercialize prototypes to provide volume production and thus minimize the cost to the government. Wilcoxon Research intends to explore applications for the sensor suite in a wide variety of uses. We envision such low-cost sensors being used for the protection of foodstuffs and medical supplies during the handling and transportation (especially, moisture and temperature), the monitoring of moving high-value and/or delicate shipments, as a way to determine if environmental limits of warranty has been exceeded, and in automotive and building control sensors. |

| Title: | Enhancements to SAAS-MOD for Increased ASP Productivity |
| Abstract: | We propose two key enhancements to the SAAS-MOD system that encompasses the major Phase I objectives. The first enhancement to SAAS-MOD proposed is the optimization of the UCL for maximally efficient collection of those items at the ASP. The added value of this optimization will be a physical" route" in which ASP personnel can physically collect items of a UCL. Once these supplies have been gathered, the second enhancement proposed is to provide software and visualization capabilities that can optimize the packing of these supplies onto a pallet or flattrack to ensure a maximum payload. ASP's will be streamlined in operational capability. Personnel will be able to more efficiently traverse the ASP and to pack materials into vehicles for movement. |

| Title: | Distributed Battlespace Management Systems |
| Abstract: | The military battlespace is a complex, dynamic, and open multiagent system requiring timely and distributed information fusion and decision making. The objective of this project is to develop a distributed battlspace management system using the advanced multiple target tracking, the recursive modeling method, the dynamic programming, and Bayesian learning techniques. The innovations of this project include: 1) application of a Markov Chain Monte Carlo data association approach for solving complicated multitarget-multisensor tracking problems using inexact inputs received from diverse sensors; 2) development of a fuzzy Bayesian network to create a situation modeling structure and computational architecture for uncertain inference; 3) development of a recursive modeling method for enabling an agent to select its action and to coordinate with other agents by modeling their decision making in a multiagent domains; 4) application of a dynamic programming technique for solving the optimization problem for autonomous agents; 5) application of Bayesian learning for updating the agent's belief about the other agents by revising the probability concerned with the other agent's model based on their observed behavior; and 6) testing, demonstration and evaluation of the performance of the multiagent battlespace decision making system using a standard battlespace scenario in an intelligent virtual simulation environment. The research results of this SBIR program will lead to the following commercialized product: Distributed Battlespace Management Systems. The applications of this technology arise in all areas of the intelligent digital battlefield, manufacturing systems, intelligent vehicle highway systems, industrial processes, and command, control, communications, and intelligence (C3I) systems. |

| Title: | Intelligent Multi-Agent Hybrid Systems Control Technology |
| Abstract: | Superior information over one's adversary allows control of the battlespace, and ultimately provides opportunities to take advantage of the adversary's vulnerability. C2 planning is critical to shape and control the pace and phasing of battlespace engagements, and requires direct access to battlespace information in order to utilize it effectively. Effective C2 requires the ability to seek out relevant information sources; connect them where their information flow contributes; monitor the information flow to determine changes to the battlespace; and reacting to those changes. Because the battlespace is dynamic, attempting to utilize standard scheduling techniques will fail. In Phase I, an Intelligent Multi-Agent Architecture will be designed that provides dynamic, distributed, and adaptive decision-making, planning and execution across C2 systems. In our approach intelligent agents are assigned to represent all available weapon-platforms in the battlespace. Other agents are used to set up data-flow paths of intelligence and targeting information through the C2 battlespace systems. When targets are identified within the C2 systems, an agent is assigned to them and that agent negotiates with the weapon-platform agents for assignment. Such market-based negotiation strategies have shown to be superior over standard scheduling approaches when the domain is as tremendously dynamic as military battlespaces. This research will support critical DOD C2 and C4I applications as well as other distributed decision making applications in autonomous unmanned vehicles and battlefield robotics. Commercial applications include: intelligent highway and air traffic control; work-cell manufacturing; industrial inspection; job-shop scheduling; intelligent robotics; personal assistants (softbots); and mobility aids for the handicapped. |

| Title: | Intelligent Multi-Agent Hybrid Systems Control Technology |
| Abstract: | As Objective Force weapon systems such as Future Combat System (FCS), Multi-Role Armament System (MRAAS), and robotic missile, gun, sensor and reconnaissance systems approach fielding, humans who must control these systems are faced with an extremely difficult span of control and cognitive awareness problem in controlling these systems. This was amply demonstrated in a recent Future Combat Command and Control (FCC2) experiment at the Mounted Maneuver Battlespace Lab (MMBL). To establish effective human control over robotic systems, we must consider the development of one or more layers of autonomous agent control of the robotic systems. This could be considered as development of robotic squad and section leaders. These agents would control between 5 and 10 subordinate systems, such as sensors or guns, with minimal guidance from human controllers. CHI Systems will develop the technology required to perform robotic command and control for the FCS UOA. This technology will be derived from ongoing research for computer generated forces, which is aimed at developing autonomous commanders for simulation purposes. The technology will be embodied within a decision aiding component designed for use with the MRAAS Fires application architecture, and will be scaleable from the individual vehicle to Unit of Action echelons. Full implementation of FCS UOA Robotic Control with other systems in the netted fires and FCS environment will provide a seamless simulation and experimentation environment for development of robotic system command and control doctrine. The technology to be developed is a critical technology which has immediate commercial applications in the hazardous waste management, firefighting, and bomb disposal domains, all of which require command and control of robotic systems. |

| Title: | Decentralized Hybrid Control Strategies for Autonomous Multi-Agent Swarms |
| Abstract: | The effective coordination of large groups, or "swarms" of autonomous vehicles working collaboratively demands the development of control architectures that emerge collective intelligence among groups of individuals. Nature, through evolution and natural selection, has optimized this behavior. Insect societies, in particular, demonstrate an organized "swarm intelligence" beyond the capacity of any individual within their troupe to understand. Although possession of similar capabilities is vital to synergize the performance of multi-agent teams for military missions, swarm behaviors cannot be predicted, only observed; resources are needed to evaluate interactions between the entities found in such force structures. In past work, our research group has generated swarm intelligence algorithms mirroring the capacity of societal insects to emerge collective intelligence. Furthermore, they have been successfully interfaced to fabricate a flexible, software system, and a globally optimal multi-agent task assignment algorithm. Orbital Research proposes extending this work to develop sets of control algorithms that may be configured to direct any swarm of autonomous agents. Phase I work will: 1) create a multi-agent simulation environment, 2) develop dynamic (recursive) control structures for on-line reconfiguration, 3) develop control structures to enable optimal prioritization for agents within swarms, 4) simulate the developed strategies for a candidate military mission(s), and 5) implement multi-agent hardware demonstrations of military relevance using the developed control strategies. In addition to filling an available niche in autonomous vehicle control, this system is anticipated to have very lucrative markets in both military and civilian arenas. Potential commercial opportunities encompass virtually any situation where multi-unit coordination is necessary such as control and simulation of microsatellite swarms, conventional and micro-robots, intelligent highway systems (ITS), and manufacturing lines where automated units must interact without human supervision. |

| Title: | Moir‚ Interferometry Measurement Device |
| Abstract: | The Army is continually assessing materiel condition in the field through a process that involves manual gaging of components. This process tends to be slow and prone to operator error. Cybernet proposes to implement a reliable rapid non-contact 3D surface shape data acquisition system to facilitate this gage measurement. Cybernet proposes the use of a Moir‚ interferometry optical ranging sensor and supporting software for the described application. The Moir‚ interferometry technique suggested for this effort uses simple visible light illumination, a fixed field-of-view with no moving parts (save for simple focusing adjustments which are performed once during setup), and has a very fine depth resolution. Cybernet Systems has developed a Moir‚ interferometry sensor that has performance capabilities exceeding 1/1000 of an inch. Cybernet's Moir‚ interferometry sensor also has a large field of view for rapid scans of large objects. Furthermore, we will leverage our extensive networking experience to create a complete system capable of retrieving data from specification databases and remotely updating inventories. The technology developed will be used to inspect manufactured parts for problems as they come off the assembly line. This should allow manufacturers to improve quality and decrease cost. |

| Title: | Multi-Purpose Portable Measurement Device |
| Abstract: | We propose to develop a simple and accurate field-portable optical device for obtaining critical dimensions for ammunition of size 5.5 mm - 8". Laser-triangulation-based inspections will be performed by passing the munition by-hand through a doughnut-shaped aperture, or in some cases, by passing a probe by-hand near the shell. Inspection results, to consist of dimensional quantities or dimension differences relative to a reference, will be delivered to a local or remote gage database. The 3DGage will be a new application of existing nascent surface profiling technology at DCS Corporation. The existing technology has been shown to be feasible but not commercially viable for anatomical surface profiling. However, armament inspection, where the surface is relatively smooth and predictable, represents a perfect fit for the DCS technology, which can obtain up to 50,000 point measurements simultaneously over a surface patch. DCS will design the 3DGage hardware and software and a database in Depot Surveillance Record (DSR) format. Experiments to demonstrate feasibility of the core concepts will be performed using existing hardware. System design testing will be performed using simulations of the surfaces and the algorithms. The Phase I Option will prepare for Phase II by obtaining a key component of the prototype 3DGage. The proposed device will be useful in many military surface profiling applications where the object is rigid and smooth. Other markets are industrial manufacturing, medical, toy manufacturing and automotive (e.g. tire inspection), where a 3D representation or dimensions of smooth, rigid objects are required. The research will also be useful to improved design of arbitrary-surface measurement devices, and could re-energize DCS' pursuit of the oncology patient positioning market. |

| Title: | Reusable, Adaptable and Scalable Decision Aids Components for Future Combat Weapon System Applications |
| Abstract: | A key technology hurdle for advanced weapon technology is that of Battle Damage Assessment and Retargeting (BDAR). In a recent experiment involving precision guided missiles, missiles could not distinguish between destroyed targets, and targets still presenting a threat. Typically, 6 missiles launched at 5 vehicles all hit the same target, leaving 4 undamaged vehicles. This led to shortages of missiles, and blue force casualties. BDAR will prevent this scenario. BDAR performs real time sensor fusion, battle damage assessment, and retargeting of in-flight precision munitions. In the BDAR concept, sensors provide initial targeting data. This feeds an effects control network, which targets precision weapons to defeat a target array. Initial targeting will distribute precision munitions appropriately by assigning the right number of munitions to the array. After launch, the munitions will begin to impact the target array, and sensors begin determining battle damage assessment. As the sensors determine that a target is destroyed, they will communicate this data to the effects control network to cause retargeting of in-flight munitions, or directly communicate with, and retarget, in-flight munitions. The decision aid will be a component of the MRAAS Fires architecture, and will be compliant with Appendix F, to the JTAA. The BDAR decision aid will be an answer to the current problem of expending scarce munitions on unprofitable targets. Complete implementation of the decision aid during Phase I and II of the proposed effort is intended to take place within the context of the MRAAS Fires program. The concepts and implementations will serve as a technical base for technology insertion into a number of Army Science and Technology Objective (STO) programs under consideration for Initial Brigade Combat Team and Objective Force operations. The decision aid component can also be applied to civilian domains such as stock quoting, logistics management, and police operations. |

| Title: | A New High Rate Process for Nanoparticle Separation |
| Abstract: | We propose to develop a new high rate process for sorting nanoparticles in the gas phase. The process also overcomes the fundamental limitation of the existing differential mobility analyzer, thereby allowing an output that is conducive to industrial use. The nanoparticle separator can be used either as a stand-alone system, or in conjunction with a nanoparticle generating reactor, such as a plasma system. The nanoparticle separator is conceptually novel since it involves strategic utilization of electrostatic forces in synergistic aerodynamic configurations, which exploits the inertia-based and/or size-mobility of nanoparticles, thereby allowing for effective size-based sorting. In Phase I, the nanoparticle separator will be experimentally demonstrated, combined with computer simulation to refine the process and scale-up to deliver an output in excess of 1 kg/hour. A scaled system will be constructed in Phase II, and integrated with a nanoparticle generating reactor in Phase II, either in-house or at the Army facility. There are several nanopowder synthesis processes, the plasma process being one of them, which yield nanoparticles with a wide size distribution. While the process is intrinsically inexpensive and scalable, the particles need to be separated based on the size in order to be effectively used in any application. Our program addresses this critical need. |

| Abstract: | This project is aimed at developing a novel motion planning and control system to increase the autonomy and dexterity of cargo handling systems. In Phase I, system architecture, processing/control methodology, component specifications, and performance analysis will be carried out. AGNC's miniaturized MEMS IMU/GPS navigation and a selected EO sensor will be employed to accurately provide both inertial and target-relative guidance signals needed to perform automated tele-operation maneuvers such as the cargo handling system's real-time motion planning/control with collision avoidance. A fuzzy logic approach will be explored and incorporated into the guidance algorithm and controller design of the cargo handling system to accommodate parameter and payload uncertainties. In addition, development of integrated software environment design and simulation package is planned, which provides user-friendly evaluation and demonstration tools for the proposed design approach. The deliverable product is a final report documenting design approaches, requirements, and modeling/simulation results. This project will lead to a generic guidance/navigation/control system with great commercial potential. Possible applications include automobiles, spacecraft, aircraft, and autonomous vehicles. |

| Title: | Adaptable/ Reusable Hardware/Software Architectures and Components for Future Combat System (FCS) Automated Resupply |
| Abstract: | Progress in the area of intelligent automation is impeded by the lack of standardized architectures that promote software reuse. Conventional design methodologies require tailored software solutions that are expensive to implement and difficult to modify. This proposal addresses the need for flexibility and reusability with a scalable architecture that supports a component-based programming paradigm. Phase I will demonstrate the feasibility of the offered approach - in the context of demanding real-time intelligent automation applications - with a suite of interchangeable hardware/software components. The robustness of components and supporting architecture will be tested in simulations. Metrics that quantify costs savings and percentage of software reuse will be used to assess potential impact of the component-based methodology. Phase II will culminate in a prototype demonstration of two different material handling platforms sharing common components. The proposed solution will provide a component-based approach for software design and implementation for a wide variety of automated material handling machines. This will enable the Army to lower development time and cost of these machines while leveraging previous work. These software components can provide equal benefit to the commercial sector by providing a software development standard for machine automation. |

| Title: | Adaptable/ Reusable Hardware/Software Architectures and Components for Future Combat System (FCS) Automated Resupply |
| Abstract: | The goal of this research program is to demonstrate that a distributed component software architecture (DCSA) affords an exceptionally reusable, adaptable, modular, maintainable, extensible and scalable (RAMMES) platform for the implementation of the upper layers of robotic controllers for quasi real-time control of demanding field materiel handling, re-supply and logistics automation for Future Combat System (FCS) applications. This program will accomplish the following tasks: 1- Evaluate, select and implement an established distributed component protocol that complies with the Joint Technical Architecture(JTA)specifications. 2- Convert Robotics Research's R2 Controller legacy materiel handling control software into distributed components. 3- Specify an R2 enterprise controller network based on network-centric computing technologies for the sub-domain framework of material handling vehicles. 4- Evaluate emerging distributed computing technologies such as interface agents, transaction servers, Java Jini, ActiveX, DNA, XML, SOAP, etc. for employment in the next generation of network-centric controllers to support FCS tasks. The DCSA will facilitate rapid deployment via "plug and play" of advanced sensor control techniques, operator interfaces, etc. It will enable the system integrator to optimize system performance and resources by adjusting component residencies and network topologies, and provide the infrastructure to support a network centric control platform. Portable DCSA technology is vital to the global effort to "industrialize" software development, in which standard components can be assembled to build complex distributed systems. A repository of proven, distributed, and portable software components will reduce development, maintenance and over all life cycle costs. Presently, commercial DCSA software packages are now offered on the Internet as high-level distributed and scalable components that address the areas of database transactions, system load monitoring, security safeguards, etc. This Internet paradigm will prove to be equally applicable to large-scale controller networks. DCSA technology encourages RAMMES software development and will be instrumental in the next evolutionary step of Internet "plug and play" devices. Moreover, DCSA serves as the foundation for Distributed Component Object Modeling (DCOM) wrapping techniques, which allow legacy code to be integrated into present and future computing environments. |

| Title: | Detection, Tracking and Classification of Multiple Targets using Advanced Beamforming and Classification Methods |
| Abstract: | The problem of detection, classification and tracking of multiple vehicles in battlefield situations is the focus of this Phase I research. Typically, multiple unattended sparse passive acoustic arrays are exploited to monitor, track and identify the potential targets. Although, the present technology is capable of successfully detecting, tracking and classifying single targets, extension to multiple targets especially when they are closely spaced pose many technical difficulties. As a result, new schemes are needed to provide fast and accurate detection and identification of different types of targets from passive arrays of acoustic sensors. To address this problem, we propose to study and develop dedicated methods for multiple target detection/classification and tracking. One primary criterion is to develop fast algorithms that don't make any a priori assumption about the number of targets, target's dynamical information and initial conditions, and background interference and clutter. We will develop a subband-based direction of arrival (DOA) estimation method for better differentiation of different tonal features of the signatures and a sequential Bayes method for target (vehicle) classification. The algorithms will be tested on several multiple target cases that involve various target scenarios, high density of clutter and correlated interference, and collected in different environmental conditions. In battlefield situations the ability to make rapid and yet very reliable decisions becomes of utmost importance in order to identify, localize and destroy the targets. This is critical to the survival of lives and material. The potential of this study for broad-based technology transfer is immense. There are several Government agencies and companies in the U.S. that involve with the development of various automatic target detection, classification and tracking systems for different active and passive sensor platforms. The algorithms developed in this research are general and can be applicable to a multitude of similar problems. Thus, the results of this research could lead to the development of many other acoustic signature analysis systems in a wide market encompassing military, environmental, and commercial areas. |
