Title:Extending the Dynamic Flowgraph Methodology (DFM) for Automated FMECA and Diagnostic/Prognostic Requirements Optimization Analysis
Abstract:This innovation proposes the development of a technical tool for automated FMECA and diagnostic/prognostic requirement optimization analysis of system designs and implementations. This tool will fill a void that is currently not addressed by any analytical techniques, where the FMECA and design optimization processes are closely integrated with the design/development cycle. FMECA results are fed into an automated optimization analysis. A graphical model of the system is developed and analyzed by means of a formal logic analysis technique called the Dynamic Flowgraph Methodology, which is capable of identifying a desirable mixture of diagnostic/prognostic capability to mitigate the effects of the critical failure modes found in the FMECAs. This innovation has high technical value and commercialization potential, as there is a widespread requirement and use of FMECA in the government and in the commercial sector.

Title:Advanced Failure Modes and Effect Criticality Analysis (FMECA) Models that Accurately and Quickly Identify Optimum Levels of Prognostic Requirements
Abstract:To develop and demonstrate an accurate and easy to use advanced FMECA modeling capability that would allow timely optimization of various aircraft subsystems. There is a need to improve and streamline the requirements definition process for diagnostic, prognostic, and health management. This should be possible in early conceptual and design stages. An advanced FMECA model can be used to identify the optimum mixture of diagnostic, prognostic, and health management capabilities. This capability would be used to aid in making the necessary trade-offs in order to define the optimum final system design. This analytical tool will be used in the development of any complex engineering system. In particular, commercial manufacturers of fixed-wing or rotor wing craft aircraft could utilize the tool to specify diagnostic, prognostic, and health management capabilities in their design. Such a tool may also be applied in non-military (offshore, civilian aircraft, marine and mining) fields. In addition it will promote application of failure analysis in other industries which currently are unable to do it due to lack of know how and financial resources.

Title:Advanced FMECA to Identify Optimum Diagnostic and Prognostics Requirements
Abstract:Impact Technologies in cooperation with the Applied Research Laboratory (ARL) at Penn State University propose the development, implementation and validation of an advanced FMECA modeling capability that can provide optimized health monitoring system requirements for existing or new acquisition Naval aircraft systems. The integrated FMECA modeling approach and specific optimization algorithms utilize a combination of conventional FMECA results, health management system strategies, maintenance/inspection scenarios, and metrics from various diagnostic/prognostic technologies to optimize the sensory, diagnostic, and prognostic system needs in terms of mitigating the FMECA identified failure modes. The proposed program will utilize advanced system optimization and evolutionary algorithms such as genetic algorithms to seek out the best health management system configurations and capabilities based on a corresponding set of "cost" or "fitness" functions that accurately represent the key system variables. Key variables such as reliability, complexity, cost, risk and sensitivity of the sensor systems, diagnostic/prognostic technologies and maintenance/inspection strategies will be addressed by this function. Hence, the effort shall be capable of identifying and ranking candidate aircraft subsystem health management system requirements, through an exhaustive search of a potentially enormous solution space considering the multitude of potential sensor, diagnostic, prognostic and maintenance technologies. Finally, this hierarchical FMECA modeling capability and health management system optimization process will be developed in an open systems architecture and demonstrated on a Naval aircraft subsystem. The advanced FMECA integrated model will be capable optimizing the health monitoring system requirements so that critical Naval system failures and high cost operation can be avoided. Costly inspection routines and premature component replacements can also be avoided. Substantial safety and cost benefits are projected if the optimal application of LRU diagnostic and prognostic techniques is realized, and it could thus provide the potential to make the correct life cycle choices during the acquisition process. Commercial applications for the FMECA modeling approach can be realized on any machinery health monitoring application in the electrical generation industries, chemical processing industries, commercial aviation as well as gas transmission and oil industries.

Title:Thin and Effective Erosion Resistant Coating for Compressor Impellers
Abstract:Blades, vanes, and impellers in gas turbine compressors operate in dusty environments and are prone to degradation by solid particle erosion. Erosion of the impeller blades can lead to potentially catastrophic compressor failure. We propose a thin ceramic-metal composite (cermet) coating based on a sol-gel process that is designed to combat erosion effectively. The proposed coating process is simple, inexpensive, and does not use materials that are hazardous to the environment. The coating consists of metallic particles bound together, and to the substrate, via a ceramic matrix. The ductile phase provides erosion protection at higher impingement angles and the ceramic phase provides protection at lower impingement angles. By varying the type and concentration of powders in the sol, coatings with the desired erosion properties can be prepared. The thinness and smoothness of the coatings ensures that the fatigue properties are not undermined by the coating. During Phase I, erosion and high cycle fatigue resistance of the proposed coating will be evaluated on Ti-6Al-4V at ambient temperature. Phase II studies will include erosion and fatigue evaluation of the coatings in various simulated service conditions and tests on actual turbine engine components. The most promising coatings will be patented and licensed as protected technology for commercial use in Phase III. Helicopters, vertical/short take-off and landing aircraft, fighter jets, airlines and power plant turbine engines will benefit from the effective and economical protection afforded by the proposed coatings. Moving mechanical assemblies (MMAs) used in spacecraft and diesel engines will equally benefit from the hard and tough coatings developed in this proposal. Some of MMAs include bearings, gears, cams, bushings, seals, valves, nozzles, and pistons.

Title:Electro-Spark Alloying Coatings for Erosion Resistant Impellers
Abstract:Shaft-driven impeller technology is a critical component in a wide range of military and commercial equipment. The high-velocity impingement of dirt and debris, and their subsequent wear effect on the impeller have been documented not only on the V-22 Osprey, but other flight systems and military ground vehicles. The uniquely high RPMs associated with this titanium impeller design make it particularly susceptible to high wear. Due to the extraordinarily high impact velocities of particles on the titanium, most conventional coatings, typically mechanically bound to the substrate, will not provide protection to extend the life of the component. However, an emerging process, electro-spark alloying (ESA), is capable of imparting a high hardness surface of only a few thousandths of an inch which will offer full metallurgical bonding to the substrate with little or no heat-affected-zone (HAZ) typical of most coating processes. ESA also provides a nano-grained surface with enhanced wear properties over their larger-grained counterparts. The proposed effort will model the particle impact to assess coating design parameters, perform coupon level coating studies, and simulate the wear environment via high-velocity particle impingement tests. Successful candidates will proceed to Phase II development. Optimized ESA surfaces will provide the additional life necessary for the V-22 to meet its mission-related life-cycle goals. This development will readily transfer to a wide range of wear/impact applications such as: other military and commercial impellers, lawnmower blades, cutting tools, nozzles, etc.

Title:Compressor Impeller Erosion Resistant Surface Treatment
Abstract:Shaft driven compressors (SDCs) are used on aircraft for a variety of functions. Although air intakes for these compressors are equipped with particle separators, in dusty environments/storms, the separators are overtaxed and unable to completely remove dust particles leading to rapid erosion of impellers. This can lead to loss of function of critical components and potentially catastrophic system failure. Surmet proposes innovative conformal coatings for imparting high erosion resistance to the impellers. Preliminary erosion tests indicate high potential of these coatings for providing erosion resistance. In Phase I, Surmet will demonstrate feasibility of achieving high erosion resistance via fabrication of coated coupons and extensive microstructural, mechanical and erosion characterization. Surmet has teamed up with a major aircraft manufacturer to demonstrate applicability of the coating to a prototype component in Phase I Option. In Phase II, the coating technology will be optimized through coating and system level characterization of a large number of components. A Phase III commercialization plan will be developed for rapid insertion of the technology in operating aircraft. Shaft driven compressors (SDCs) are used in a variety of military and commercial aircraft. Development of erosion resistant coatings for SDCs will prevent rapid erosion and catastrophic system failure in dusty environments, prolonging component life and reducing life cycle costs. Erosion resistant coatings will also have application in commercial equipment such as pumps, compressors, energy generation equipment (erosive effluents), mining equipment, etc.

Title:Auto-correlation of Elevation Data from Digital Stereo Imagery
Abstract:Relative to the stated US Navy interests in auto-correlation of elevation data for support to the Cruise Missile Command and Control (PMA 281), our technical objectives offer a linear analytical approach to this SBIR. Our first objective is to conduct an operational requirements analysis to define the operating environment of the digital correlation solution and its interfaces to source data and target systems. Next, we will investigate the specific functional requirements that define the processes that must exist within the solution. Third, we will examine the performance requirements to include such variables as timing, output quality of the solution, impacts upon digital correlation results, estimation of improvement gains in minimizing interactive editing, and accuracy requirements. Fourth, we will investigate the PTAN requirements that will affect the output of the DEM required for the reference map. Finally, we will analyze the optimal digital correlation approaches as defined by the prior tasks. Under a planned Phase I Option, we will also focus on the architectural design for Phase II prototyping, and conduct a market survey quantifying the potential success of a related fielded product. A number of opportunities for a digital correlation solution exist in the marketplace. The most promising involves providing solutions to commercial satellite systems vendors and their value-added resellers and product generation partners for sale and resale. Also, remote sensing/GIS vendors should be receptive to reselling a solution as an add-on or replacement of their existing digital correlation capabilities. Lastly, DoD, intelligence, and defense mapping agencies worldwide are potential customers of bulk sales of the solution. During both Phase I (Option) and Phase II, research into all logical marketplaces will be performed to finalize anticipated revenue levels and per unit pricing. We believe at this point that the market value for the solution will be in the $7,500-$10,000/copy range, with embedded versions resold by partners for roughly 30-50% off standalone pricing.

Title:A Device for In-Situ Evaluation of Vehicle Wiring Systems
Abstract:Aircraft system wiring has become a primary concern for aircraft safety. The Air Force has identified aging wiring as a cause of aircraft fires and is a major driver of ownership costs. This proposal will explore making a passive Sentient Wiring Connector (SWC) that will instrument wiring in aging aircraft. The low cost, multi-sensory SWC has significant advantages over labor intensive and expensive ground based systems. The SWC can save millions of dollars in operations and support costs over the remaining life of the aircraft. The SWC will process data from multiple sensors into information used for detection of signs of aging. The SWC can be inserted into the wiring itself to check for wiring continuity, breaks in electromagnetic shielding, water in harnesses, cocked connectors, and corrosion as well as inspecting the health status of the wiring insulation. The SWC connected to subsystems (avionic unit, engine, transmission) will be able to monitor many of that system's vital health signs. Used in flight, the SWC will detect loose pins, intermittent problems, missing clamps, abrasion, and other factors impossible to detect during ground inspections. The SWC will also send processed information to a web-page database for continuous monitoring of the aging wiring. Aircraft certification, vehicle safety liability concerns are major reasons for utilization of the SWC technology. The product will have broad application in inspection of commercial and military aircraft. The SWC will be an enhancement to present health management systems. With minor changes in format the SWC will also have uses in monitoring wiring of ships, mass transit systems, vehicles and buildings.

Title:Wiring Diagnostics Using the Smart Universal Sensor Interface (PR00-001)
Abstract:We propose to research, design, and develop active and passive signal and cable diagnostic capabilities for our Smart Universal Sensor Interface (SUSI). SUSI is designed to accommodate more sensors than conventional avionics sensor units, using fewer wires, less power, and at greater data rates and shorter delays, while consuming less physical space. In addition, SUSI provides advanced features such as: upgrades to optical avionics networks, full compatibility with legacy systems such as AATIS, CAIS, 1553, and ARINC; serial sensor buses to further reduce wire count; smart functions such as described in the IEEE 1451.2 standard; and extensive local processing and data storage capability. SUSI is designed to be modular to a very high degree - even the network interface can be changed by simply replacing the network module. These advanced features can be used to implement diagnostics and health monitoring functions for a wide range of applications, including wiring diagnostics. Since SUSI integrates into the avionics system and is designed to take data and control actuators, there is no added overhead (weight, cost, etc.) for additional instrumentation. This system could provide critical data not only for safety purposes but for maintenance as well, thus helping to extend useful aircraft life. Both military and commercial aircraft could benefit from advanced smart sensor systems capable of providing real-time data on subsystem health.

This will produce a non-contacting seal capable of long life under high surface speed and temperature conditions, and be capable of reverse rotation. During Phase I a proof of concept seal will be manufactured and rig tested. The ATS seal will increase thrust and decrease specific fuel consumption for all turbine engines

Title:Nanocomposite Coatings for Aircraft Transparency Protection
Abstract:Triton Systems proposes to develop novel, polymer-inorganic nanocomposite coatings for the polycarbonate and acrylic surfaces of the F-18 and other aircraft transparencies. Triton's polymer-inorganic nanocomposite contain nanometer scale inorganic filler particles that enhance the chemical resistance, abrasion resistance, and overall protective properties of the coatings. Our novel nanocomposite coatings will be solution-based and easy to apply on the F-18 transparency and will provide excellent optical transmission characteristics with minimal haze and no distortion. In addition, these coatings will improve flame resistance, and barrier to chemical and biological warfare agents. These coatings will significantly extend the service life of transparencies and reduce the operation and support costs of windshields and canopies in the field. These coatings will find application in a variety of other Navy, military and civilian applications such as aircraft windows, helicopter transparencies, vision block for vehicles, face shields and goggles for soldiers and chemical laboratories.

Title:Intelligent Tutoring System for Tactical Aircraft Training (ITS-AIR)
Abstract:Technical Abstract (Limit your abstract to 200 words with no classified or proprietary information/data.) Benefits of low-cost, high-fidelity, self-contained deployable training units, such as TSTARS, include increased availability of on-location training with reductions in travel expenditures, personnel time lost at training locations, and geo-specific training centers costs. However, the cost of providing on-site personnel to assist the student represents a significant drawback of current simulation technology- particularly considering the reduced manning-level environment of current military budgets. But, this need not remain the norm, as prototypical simulators of the future will, themselves, be capable of adaptive training techniques best suited to current students needs without requiring assistance from specialized simulator personnel. SDS's ITS-AIR innovations, utilizing COTS components from Soar technology, USC, STOW/BMH and ModIOS within a rapid prototype environment through reuse of the SDS LiteFliteT Reconfigurable Flight Simulator, will be used for assessing an instructorless intelligent tutoring system. Prototyped intelligent agents will be utilized for investigations into reducing manning levels for deployed training systems. Further, Soar-based AIR-SF, STOW/ BMH tools and Motorola ModIOS tools will be used as the basis for After Action Review and mission rehearsal components. Use ofLiteFliteT will be provide leverage as a placeholder for the TSTARS system planned for Phase II. There are multiple classes of Commercial Applications for ITS-AIR associated technologies. Military Aviation, Commercial Air Carriers and General Aviation will be the first to benefit. ITS-AIR could be added as an option on existing or new aircraft simulators. Potential benefits include reduced manpower costs, enhanced performance, increased standards, and early teaching of optimal methods to pilots. In fact, ITS-AIR, when coupled with student pilot motion sensors and eye tracking technology, could provide a comprehensive method of measuring differences from expert performance in well defined training scenarios. The sale of turnkey systems-- ITS-AIR "Kits"--will allow early product commercialization, particularly within the commercial and general aviation markets. General transportation, including transports, freighters, recreational boats and racecars, would also benefit from the research and development done for aviation. SDS plans to identify numerous lucrative internet markets. These markets, like the aerial, marine and land markets, require extensive up-to-date domain databases. A potential avenue, which SDS plans to explore, is teaming with an organization(s) currently providing domain specific databases, utilizing intelligent agents to automatically retrieve updates. Since any computer based training program can benefit from the introduction of automatic operator assistance and adaptive training techniques, Intelligent Tutoring technology has broad-based appeal. For instance, aerospace systems can train new features.

Title:Intelligent Tutoring System for Air Tactics
Abstract:Next generation mission rehearsal training systems, such as the Transportable Strike Assault Rehearsal System (TSTARS), will be smaller and more easily reconfigured, so they can be deployed aboard aircraft carriers and used by pilots to configure and practice missions while at sea. However, if scarce and costly human instructors are required to operate these new systems and provide instructional feedback to pilots, the potential "any-time, any-place" benefits offered by these systems will be significantly reduced. SHAI proposes to develop an air tactical ITS (ITS-AIR) which would provide pilots with instructional feedback automatically and help them operate the simulator without human instructors. Our system will employ template-based student performance evaluation, automated feature extraction from the simulation data, temporal inference, application-specific knowledge editors, and adaptive instruction. This approach will result in a sophisticated tutoring system whose knowledge base can be maintained by SMEs without programming. SHAI will team with cognitive psychologists at Klein Associates who will help us carry out a preliminary Cognitive Task Analysis and provide relevant results of prior CTAs. Mr. Lloyd Prince, a former Naval aviator, will serve as a subject matter expert. We will design, develop, and demonstrate a prototype system which illustrates our approach. The aviation ITS technology developed for ITS-AIR will enable automated tutoring system add-on products which complement military and commercial aviation simulators, sold through simulator vendors and directly to military and commercial aviation end-user organizations.

Title:Environmentally Insensitive Active Decluttering
Abstract:Active sonar operations are a key to achieving effective USW performance in littoral waters. The performance of active sonar in these scenarios is often clutter limited. Most traditional active decluttering approaches have identified classification clues that are used to try to discriminate target echo returns from clutter echo returns. These approaches have historically suffered from performance sensitivity to changes in the environment and to limitations of the data used to tune the algorithms. DSR proposes an approach that will extend well-known detection theory concepts to the problem of active decluttering and classification. It turns out that some of these concepts have already been used in various classification implementations, though the implications of the detection theory performance were not pursued within the structure of the classification problem. DSR's effort will result in definition of MOE's, specification of processing algorithms, and evaluation of performance against existing sea data. Completion of this effort (Phase I and Phase II) will lead directly to integration of an environmentally robust active acoustic decluttering capability for the Navy's SH-60R Platform.

Title:Environmentally Insensitive Active Decluttering
Abstract:Active sonar systems face a significant decluttering problem especially when operating in shallow water. In future multi-static, multi-receiver search missions, the number of alerts is expected to increase dramatically. Tactical scenarios present a further complication because response time is critical and, as a result, classification in the fewest number of pings is crucially important. Historically, the decluttering issue has been addressed by estimating parameters of active acoustic returns and comparing those returns against thresholds. Unfortunately, these thresholds are highly sensitive to the environment. The proposed Phase I research intends to develop environmentally robust signal processing algorithms that significantly reduce clutter, improve detection, and perform quickly. To address these issues, the Phase I effort proposes three tasks. The first is to define a CFAR threshold based on the (possibly) non-Gaussian statistics of the matched filter or energy detector output. The second is to develop a classification metric based on acoustic returns for distinguishing targets from clutter. The third is application of an in-situ enhanced environmental model, which provides feedback to the classification metric for measurement and analysis. Each of these tasks will contribute to the SBIR goal, which is to reduce clutter and sensitivity to environmental conditions The anticipated benefits of the Phase I research include development of environmentally robust operator aids for significant clutter reduction, and improved detection and classification performance. This has benefit and applicability to a wide variety of Navy platforms and programs, including SH-60R. For future multi-static, multi-receiver search missions, 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.

Title:Multistatic Operation
Abstract:Active sonar operations are a key to achieving effective USW performance in littoral waters. A capability that has been largely untapped in USW operations is bistatic operations between the SH-60R platform and surface ship assets. Historically, bistatic studies have addressed improvement of wide-area search performance. In this effort, DSR will instead investigate the performance improvements that bistatic operations can provide to the USW Middle and End game scenarios. DSR will consider an SH-60R platform acting bistatically with a surface ship that has both AN/SQS-53C and MFTA subsytems. The Middle and End game scenarios provide enough information about the target that determination of source/receiver deployments yielding desirable bistatic geometries becomes feasible. DSR will define MOE's, develop a performance model, evaluate potential performance improvement, and develop a preliminary concept for an Integrated Bistatic Post- Processing System. This new Integrated Bistatic Post-Processing System will also be able to assist the operator as a planning aid since it will determine recommended source/receiver deployment strategies. The processing will select desirable deployment strategies based on the effect of bistatic geometry on target strength, Doppler shift, reverberation level, localization error, target motion, and platform covertness. Completion of this effort (Phase I and Phase II) will lead directly to introduction of bistatic planning and bistatic processing capability into the SH-60R Platform.

Title:Multistatic Operation
Abstract:Multistatic/Multiplatform ASW capabilities are needed to counter the improvement in capability of enemy submarines deployed by potential adversaries. The need exists for systems that provide a wide area search capability while at the same time providing sufficient standoff distances for friendly forces. Multistatic/Multiplatform operations can fulfill this need by providing opportunities for multiple target detections, improved localization, and improved classification. Each ASW platform brings unique capabilities to the conduct of the mission. For example, the air platforms are highly mobile and are capable of searching a vast area by deploying a large field of source and receive sensors. The surface and subsurface platforms have the capability to produce high source level and deploy receive arrays with high directivity gain. If the Navy is to continue to keep pace with the improving submarine threat, there clearly exists a need to develop systems that combine the inherent strengths of each platform to improve overall ASW mission effectiveness. In this SBIR we address two multistatic scenarios to a level of detail necessary to assess the potential improvement in ASW effectiveness. The product of this SBIR is intended to be of use to the SH-60R and surface platforms equipped with the SQS-53C sonar. Making SH-60R and surface platform capable of integrated ASW operations will significantly enhance the ASW performance of both platforms in both the search and localization phases of the mission. The innovative concepts under development in this SBIR are intended to enhance the effectiveness of this multiplatform system.

Title:Tracking Multisensor Data
Abstract:Evolutionary algorithms are proposed to assist in tracking multisensor data. A common protocol is for a tracker to receive time-sequenced reports from multiple sensors (often of different types). Each sensor may or may not report a detection. The tracking problem is to assign each detection to a track, or start a new track. The number of different ways for combining targets into tracks over time increases very rapidly. Such combinatorial problems are often well suited for evolutionary algorithms. The approach proposed here is to evolve tracks online as data are acquired and adapt those tracks in light of new data as they become available. Scalable tracking based on observations from mutliple different sensors is useful in a variety of commercial shipping applications, as well as satellite overhead imagery.

Title:A Context-Adaptive Multiple-Hypothesis Approach to Multisensor Air ASW Tracking and Data Fusion
Abstract:The Navy needs an effective integrated approach to data fusion and tracking for a heterogeneous air-deployed sensor field. The data fusion architecture must properly handle bearing-only, range-bearing, and other multistatic measurement types, must model sensor-dependent measurement characteristics and accuracies, and should use data association/fusion algorithms appropriately matched to the current sensor, measurement, and environmental characteristics. ORINCON proposes a solution based on an algorithm-adaptive variant of a proven multiple measurement-type multiple-hypothesis tracking capability. Specifically, ORINCON proposes to develop and demonstrate a prototype Air ASW adaptive fusion architecture enabling dynamic intelligent selection and switching among multiple kinematic data fusion algorithms based on the situational context (for example, currently available measurements, or clutter density). ORINCON has shown that adaptive fusion algorithm selection and switching leads to significant improvements in multisensor tracking performance; the approach will enable effective fusion across dipping sonars, sonobuoy sources/receivers, and other acoustic or nonacoustic sensors. ORINCON will demonstrate the prototype on real recorded data, and will quantify performance using specific track quality metrics. ORINCON will optionally quantify performance so as to infer maximum measurement gaps, and therefore recommendations for field deployment strategies. Phase II will include additional kinematic fusion algorithm and attribute/classification fusion algorithm extensions. The proposed fusion architecture will lead to dramatically improved performance, critical for the projected full spectrum dominance under Joint Vision 2010. The open, modular architecture provides for flexibility and growth with the SH-60 or MPA systems. The Navy will experience payoffs via the leveraging of existing technology and the applicability to surface-, subsurface- and land-based systems. Finally, the data fusion architecture could be used for nonmilitary multisensor tracking applications such as seismic exploration or off-coast drug interdiction.

Title:Autonomous Neurofuzzy System for Tracking Multisensor Data
Abstract:In response to the U.S. Navy solicitation for Tracking Multisensor Data, Physical Optics Corporation (POC) proposes to develop an autonomous multisensor tracking system (AMTS). The proposed AMTS will combine POC's proprietary neurofuzzy control and distributed data tracking methodologies. The proposed neurofuzzy AMTS will have three innovative advantages: autonomous tracking capability, minimizing operator interaction; autonomous incorporation of information from both passive and active sonobuoys; autonomous multistatic operation with sonobuoys and dipping sonars. The core of the AMTS is the Neurofuzzy Tracking Control System (NTCS), which consists of a signal validation module, a data alignment module, a data association in module, and a data correlation module. These NTCS modules control each step of overall tracking based on multisensor data, making use of the expertise embedded by POC's neurofuzzy technology. In Phase I, POC will demonstrate the feasibility of AMTS by means of computer simulation. In Phase II, POC will build a fieldable AMTS based on Phase I results. The immediate application for AMTS is ASW tracking based on data streams from multiple sonobuoys and dipping sonars. The AMTS can also be used for automatic multiple target tracking, air traffic control, satellite tracking, and inventory tracking.

Title:Military Utility of Automatic Dependent Surveillance - Broadcast (ADS-B)
Abstract:Navy and Marine Corps tactical aircraft must make a significant transition in avionics functionality if they intend to retain access to worldwide sovereign controlled airspace. The stand-alone avionics systems of today must be replaced with integrated sensors and displays that can achieve the new required level of performance in Communications, Navigation, and Surveillance (CNS). Self-reporting surveillance known as Automatic Dependent Surveillance-Broadcast (ADS-B) with a Cockpit Display of Traffic Information (CDTI) will require integrated systems. This SBIR will study the impact of Mode S and ADS-B on current military Tactics, Techniques, and Procedures (TTP) and evaluate their potential military utility. Phase II of this SBIR will install integrated ADS-B in a Navy aircraft and demonstrate its functionality for both civil and military operations. Phase III, the commercialization effort, will establish DCS Corporation as a center of excellence in CNS core integration architecture, systems engineering services, and computer based training devices ready to assist other military and civilian platforms make this transition. This SBIR will allow the military to study the mission utility and impact of ADS-B and CDTI in current operational environments and develop an affordable path to integrate this new level of situational awareness into other fleet aircraft. ADS-B is based on civil technology. The hardware and software developed and demonstrated during this SBIR effort should have many applications for General and Business aviation. The Cargo Airlines Association is evaluating the potential of ADS-B for traffic awareness and deconfliction. ADS-B utility for general aviation is being evaluated in Alaska with the Capstone Program. Over the next 10 years there will be many business opportunities associated with ADS-B functionality, including systems engineering services, aircraft modifications, computer based training and unique software applications.

Title:Military Utility of Automatic Dependent Surveillance - Broadcast (ADS-B)
Abstract:ADS-B technology holds great promise for providing the U.S. Navy with a number of significant benefits. These benefits are derived from an improved tactical picture for both command and control personnel and pilots. They include improved safety through better situational awareness and reduced pilot workload, and improvements in tactics, techniques and procedures, such as higher confidence levels in the tactical picture that might allow engagement of the enemy without visual identification. Other benefits include time and resource efficiencies, collision avoidance, range clearance and compatibility with aircraft operating in the NAS and civil aircraft in foreign airspace. Globally, ADS-B holds the promise of being the core of a new global surveillance network, and the military should evaluate mission needs at this stage during the formative stages of ADS-B development and implementation. Rannoch has unique insight into the future of ADS-B. We actively support RTCA committees on ADS-B standards development. We have designed, manufactured, and deployed ADS-B equipment. Our rapid avionics prototyping capabilities as well as our tools and techniques enable us to assess the military effectiveness of ADS-B for the Navy. As new common avionics programs are being considered, it is time to start laying the groundwork for Navy ADS-B implementation. Anticipated Benefits: Improved tactical picture; Reduction in misidentified targets; Reduction in False Replies Uncorrelated in Time (FRUIT) ; Reduction in overlapping (garbled) signals; Improved command and control in a military theater of operations ; Saves time and assets by reducing the number of missions required to identify unknown targets ; May enable the use of beyond visual range weapons; Improved situational awareness for controllers and pilots; Collision avoidance; Reduces pilot workload ; Range clearance; Compatibility with civil aircraft operating in NAS and foreign airspace. Commercial Applications: Provides enhanced radar coverage in areas that are below the sweep angle of conventional terminal or enroute radar antennas; Provides radar coverage for airports without conventional radar; Provides an inexpensive air traffic control radar system for countries that do not have a ground based radar infrastructure; Provides enhanced situational awareness to airport operations vehicles and airline support vehicles to help eliminate the growing problem of runway incursions; Improves airline gate operations, enabling the monitoring of all aircraft and vehicles in the gate area; Provides collision avoidance capabilities similar to TCAS, but sized and priced for smaller general aviation aircraft .

Title:Military Utility of Automatic Dependent Surveillance - Broadcast (ADS-B)
Abstract:Sensis proposes an ADS-B system which meets the needs of the military. The system proposed is a complete replacement to the current IFF system for the purposes of situational awareness and combat identification. The proposed system uses a Low Probability of Detection (LPD) waveform and encryption to protect the data from interception or spoofing from enemy forces. The proposed system has the potential of being installed in every US military aircraft in addition to allied aircraft as well as in ground infrustructure throughout the world. In addition to the military market, the radio technology developed has potential markets in civilian aviation. These markets include its use in Sensis's airport vehicle tracking system and as an alternative civil aviation ADS-B system.

Title:Low-Cost Precision Missile Trackers for Directional Infrared Countermeasures (DIRCM)
Abstract:There is a need for IRCM system counter threats that are difficult to defeat using conventional IRCM techniques. Because the new generation of threats are more capable, IRCM energy must be directed at the missile threat to obtain sufficient energy on target to cause it to miss the aircraft. In order to attain the energy on target, an IR jammer must be able to track the threat missile with enough accuracy to point a laser at the seeker. Current IR detectors in tracking sensors are expensive and must be cooled in order to achieve the sensitivity needed to track IR missile threats in all phases of flight. The coolers used with these detectors are the least reliable part of the sensor. These coolers cause a reduction in the reliability of the tracking sensor, increase maintenance requirements, and increase the cost of the sensors. Developing an uncooled IR detector for the tracking sensor will reduce the design complexity, reduce the production costs and increase the reliability of the tracking sensor. The miniaturized uncooled image intensified charge coupled device (I2CCD) system that is the subject of this Phase I SBIR will provide low cost, compact, high reliability precision tracking device for a variety of defense and civil airborne platforms. Beyond the obvious protection of fixed and rotary wing military assets, the precision tracker can support antiterrorist assets, coastal reconnaissance aircraft, and governmental and personal aircraft flying in high-risk areas worldwide.

Title:Low-Cost Precision Missile Trackers for Directional Infrared Countermeasures (DIRCM)
Abstract:Missile warning and countermeasure (CM) systems play a critical role in the survival of many ground- and air-based vehicles operating in hostile environments. The CM protection may take the form of an active system like a laser source intended to disrupt the guidance of an approaching missile. To direct the laser at the approaching threat missile, the CM system must be able to accurately track the incoming missile. To track the incoming missile, IR sensors may be used. For improved sensitivity, these sensors employ a cooling system, which increases the cost, weight, and complexity of the sensor, while adversely affecting its reliability. We propose to assess the suitability of uncooled sensors for tracking incoming missiles. Specifically, we will consider the use of image intensified CCD (I2CCD) sensors which are relatively mature and inexpensive. Through the proposed effort, we will accomplish several objectives - Determine the signature of several threat missiles in the waveband from 0.5 - 1.1m. - Survey the current capabilities of I2CCD cameras operating in these wavelengths. - Assess the suitability of I2CCDs for tracking the threat missile signatures - Assess the angular tracking precision that can be obtained using an I2DCCD The proposed research offers potential savings in cost and improved reliability of optical tracking systems compared to a cooled IR sensor. These advantages are multiplied when the potential replacement can be made on a class of system that is widely deployed, for which cost, weight, and size, and reliability are important concerns. The suitability of the I2CCD sensor for potential applications depends on the in-band scene radiance, both for the objects of interest and any background. For the proposed research program, this radiance comes from tactical missiles - and has not previously been well-characterized in the proposed waveband. Thus, this effort will contribute to the body of knowledge regarding tactical missile signatures. The benefits of refining and applying uncooled IR cameras are very commercially viable - reduced cost, size, and reliability - and apply to a variety of different potential applications. As remote sensing and video surveillance become more accessible, the uncooled IR systems offer a practical and inexpensive means for extending the observations into the IR wavelengths for low-light or night-time, unilluminated situations.

Title:Middle Game Localization Utilizing Air Deployable Active Receiver (ADAR)
Abstract:The objective of this research is the evaluation of the passive capabilities of the ADAR sensor, and the specification of algorithms and systems for utilizing the passive data received by the sensor. AHA will employ advanced simulation and modeling techniques to perform the evaluation part of this research, evaluating both the existing passive capability of the ADAR buoy, and the potential capability given the implementation of processing improvements. The evaluation will ensure the correct assessment of true value added to the total ASW mission through the inclusion of each phase of the mission. Measured data from appropriate littoral environments will be used to guarantee the applicability of modeled results to the real world. In the algorithm specification phase of this research, AHA will define an ADAR passive processing system architecture that includes the core signal processing functions for passive signal detection and a design that will readily accept future algorithm improvements. We will also define and conduct an initial performance assessment of candidate spatial processing, signal detection, and classification/localization algorithms that will provide a strong R&D baseline for passive ADAR. This performance assessment will also provide passive sonar equation variables for use in the model-based evaluation part of the research. The anticipated benefits of this research are the specification of advanced signal processing algorithms for the use of passive data in Air ASW missions. In addition, advanced modeling techniques will contribute to modeling efforts both within the Air ASW community and throughout the Navy. The processing algorithms identified through this research will be useful in adding capability to the IEER mission. In the future, Navy programs and research efforts such as the Advanced EER (AEER) and the Super-ADAR will benefit from this research in algorithm development.

Title:Middle Game Localization Utilizing Air Deployable Active Receiver (ADAR)
Abstract:This SBIR proposes the development of a passive processing, detection, localization, classification, and display format system for the Air Deployable Active Receiver (ADAR) sonobuoy. This system will be capable of operating concurrently with the active processor but in the background with minimal or no operator action required permitting the operators to concentrate on active detection. This proposed system would be compatible with existing aircraft processing system, which utilize the ADAR sonobuoys. The system is unique because it would operate autonomously, provide a passive capability for the ADAR sonobuoy, and utilize a localize before classification concept. This proposal includes quantifying the passive ADAR capability in shallow water against slow quiet targets; defining and developing new algorithms required to provide autonomous, full spectrum passive detection, localization and classification; estimating the signal processing resources required to perform the task; and defining the interface with the existing ADAR active operator tasking. The proposed system would provide enhanced passive detection, additional classification capabilities, and submarine speed denial capability. This signal processing will satisfy a critical need for a behind the scene multi-spectral passive acoustic signal processor algorithm utilizing the array gain of the existing ADAR sonobuoy and establishing a full spectrum active/passive capability. Commercial markets can benefit by utilizing the autonomous architecture and signal processing techniques for developing "smart" household consumer products, to conduct multi purpose tasking during marine mammal operations, off shore oil exploration/drilling, cable/pipe laying surveys and coastal environmental studies.

Title:Joint Optical Air Data System
Abstract:The Molecular Optical Air Data System (MOADS) is a compact optical instrument that can directly measure wind speed and direction, temperature, and density of the air ahead of an aircraft. From these measurements, all of the air data products can be determined. MOADS is a direct detection system (i.e., it is based on incoherent rather than coherent detection) and does not require the presence of aerosols to make these measurements. This low observable system replaces pitot probe and alpha/beta sensors and has the growth potential for wind shear detection and gust alleviation/clear air turbulence. A significant level of investment has gone into the existing MOADS prototype, which is scheduled for a flight demonstration in March, 2000. This Phase I effort will result in a design for the next generation MOADS instrument based on JSF air data requirements. Based on lessons learned from the existing prototype, specific improvements have been identified that will increase the accuracy and update rate of the next system. A technology maturation path for critical items, such as the laser, will also be identified. Through the Alternative Technology Air Data System (ATADS) study and current programs, MOADS was shown to be a viable option as an Air Data System by meeting the performance and installation requirements of a high-dynamics, tactical aircraft. The potential exists, therefore, for application toward JSF and other tactical and commercial aircraft. The opportunity presented in this SBIR is also significant in that it allows us to begin considering other applications of MOADS in addition to measuring air data products. The multiple-use of MOADS as a wind shear, gust alleviation, clear air turbulence sensor greatly expands the market potential into the commercial realm.

Title:RAYLEIGH-MIE LIDAR FOR OPTICAL AIR DATA
Abstract:OPHIR Corporation is proposing to build a system that will use optical remote sensing to replace traditional sensors now used on jet aircraft for collecting air data. The proposed system will collect light scattered from an ultraviolet laser beam by both air molecules and aerosols ahead of the aircraft in undisturbed air. The Rayleigh (air) and Mie (aerosol) scattering will be separated from each other by using their different frequency response characteristics. The aircraft's airspeed will be found from the Doppler shift of both the Rayleigh and Mie scattering, and will therefore not fail if the air becomes too clean because of lack of aerosols. Measuring the airspeed on three perpendicular axes will allow the aircraft orientation relative to the air to be measured. Then, by fitting the measured Rayleigh lineshape with a theoretical lineshape, the air pressure and temperature will be found. While traditional air data sensors perform well, they have significant limitations in performance and maintainability that impact safety and life cycle costs. This is true for both commercial and military jet aircraft. In addition, traditional sensors have proven difficult and expensive to integrate onto low-observable aircraft. In this phase I effort, the potential to overcome all of these limitations with an optical air data system (OADS) will be demonstrated by analysis and its baseline design completed. The proposed system has commercial application in three Aerospace markets: Flight Test Groups, Military Aircraft, and Commercial Aircraft. The system has the potential to overcome limitations in traditional air data systems at considerable economic benefit. A successful system could one day become a new air data system standard for aircraft.

Title:High-Power UV Lasers for OADS
Abstract:The benefits of using an Optical Air Data System (OADS) on new high-performance aircraft will never be realized until a simple, rugged, light-weight laser source has been developed and demonstrated. Systems currently under test can provide update rates for velocity and angle-of-attack that are well below those required for flight, and it is estimated that on the order of 5 watts of average power near 250 nm will be required in a fielded OADS. Although this power level has been demonstrated by several laboratories, shrinking such a system, and improving its reliability and tolerance of temperature fluctuations, vibration, and shock is more than a simple engineering exercise. Fundamental changes in resonator design, thermal management, and especially harmonic conversion technique will be required to meet this goal. Essentially, the laser source needs to be redesigned from the ground up, with the OADS requirements in mind. We intend to replace the oscillator/amplifier used in our commercial UV laser with a single, high-power oscillator, and employ a resonant quadrupler containing both the nonlinear crystals LBO and CLBO. We will also investigate line-narrowing, and, for the optional task, the development of a tuning capability. Potential commercial applications include via hole drilling and other semi-conductor industry materials processing, UV photolithography, and stereolithography. Lidar applications in addition to OADS include pollution detection, chemical and biological weapons detection, and upper-atmosphere studies.

The opportunity now exists to apply this technology to produce an infrared detector based upon parametric conversion that can out-perform existing conventional detectors used for LIDAR systems at near infrared wavelengths. A new type of infrared detector will be developed that has greater sensitivy than existing detectors for use at near infrared wavelengths. Applications include infared sensors, missile seekers, LIDAR sensors, medical diagnostic sensors.

Title:Ultra-sensitive OPA Lidar Receiver
Abstract:Significant improvements in the detection capability of weak LIDAR return signals can be achieved by optically amplifying the signal prior to detection. An optical parametric amplifier (OPA) can provide high gain, low noise, and wavelength-agile operation with spectral and spatial filtering. CTI proposes to develop an OPA-enhanced receiver that will increase the sensitivity of LIDAR detection by almost 30 dB. However, an improvement in the nonlinear optical (NLO) conversion is required to reduce the pump power requirements to practical values. The proposed Phase I effort will investigate several technology paths to achieve this goal: (1) photonic bandgap semiconductor heterostructures, (2) new phase-matching techniques and novel geometries in semiconductor materials, and (3) NLO waveguide architectures. CTI has successfully completed a program that investigated and demonstrated a NLO converter to frequency-shift eye-safe LIDAR signals to visible wavelengths to greatly enhance the detection sensitivity. Furthermore, our proven ability to design and engineer rugged, flight-qualified LIDAR systems will ensure a successful overall development program. In Phase I, CTI will conduct detailed analyses and laboratory demonstrations to evaluate next-generation OPA designs. In Phase II, an ultra-sensitive OPA receiver will be tested and delivered. (1) increase detection sensitivity in eye-safe laser radar systems, (2) reduce laser source requirements for military and industrial active imaging, thus reducing both system size and cost, (3) provide new technological approaches for designing ultra-sensitive mid-infrared detectors enabling new commercial products.

Title:A Field-Oriented Operator-Machine Interface Architecture for Multisensor, Multibeam Air ASW Systems
Abstract:Multistatic, air-deployed sonobuoy fields provide a powerful and unique means of detecting and classifying the shallow-water ASW threat. However, the typical number of sensors deployed and the increasing number of sensor beams processed place unreasonable operational demands on the user and may result in unacceptably long decision times. The Navy is in need of a new Air ASW operator-machine interface (OMI) approach that reduces search time and eliminates beam paging, that facilitates full field search and analysis, and that provides local environmental or historical context for immediate comparison. ORINCON proposes an OMI concept centered on the geographic scene. The concept allows the operator to view all sensor data simultaneously and interrogate this data in parallel based on his prioritization or as prompted by automated classifiers. The OMI concept uses display intensity and color to represent information from multiple sensors (raw or normalized data), automated classifiers (providing interrogation prioritization), trackers (providing historical context), and environmental databases (providing environmental context such as bathymetry or predicted signal excess). ORINCON will develop display requirements for this approach, identify typical field search sequences, and prototype the resulting display and search sequence concept. A fully operational display architecture will be achieved in Phase II. An improved OMI will result in improved Air ASW operator performance, reduced detection and classification time late, and reduced total operating cost even as sensor technology improves and becomes more complex. Efficient, effective methods for displaying time-critical tactical information and increasing the information coding dimensions via color and texture are also marketable far beyond the sonobuoy processing application. Examples include future nonacoustic sensor displays (radar, electronic combat, EO/IR) and enhanced tactical and operational decision making displays for area air defense and surface warfare missions.

Title:Multibeam Sonobuoy Operator Displays
Abstract:Acoustic Undersea Warfare (USW) with sonobuoys is characterized by a large amount of real time data, containing intermittent contact to a target of interest from geographically separated receivers. Methods that improve the communication bandwidth between the USW system and the operator such as advanced data visualization and spatialized audio have not been employed. These conditions establish a significant opportunity to improve the "operational effectiveness" of USW with a relatively low investment. The addition of automation has the potential to dramatically increase the search efficiency of the operator by reducing the need for manual data navigation for search. Since neither automation nor manual detection can address all cases, these capabilities need to be integrated to complement and support each other. Automation and the use of advanced display concepts to simplify the Operator Machine Interface (OMI) are required to streamline the process and present a unified tactical picture to enable a single operator to manage all sensors and contacts. This unified tactical picture can be merged with the battlegroup tactical picture held by the ASWC on the command ship in a net centric warfare domain such as that being created by the Advanced Undersea Warfare Concepts (AUSWC) initiative. The benefits of the products of this SBIR are not confined to the NAVAIR community, but rather, span the entire UnderSea Warfare (USW) community. There is an opportunity to improve the "effectiveness" of the Fleet with a relatively low investment and guarantee continued tactical superiority. The multiple sonobuoy management displays developed under this SBIR will directly support the Advanced Undersea Warfare Concepts (AUSWC) initiatives currently underway in the Navy advanced development community by providing each participating vessel in the USW Internet with a means of viewing this data, maximizing the effectiveness of interplatform collaboration in the sonobuoy information domain. The results of this project are anticipated to have application to both commercial and military systems. Initially, this product would be best applied to government agencies and DoD where real tactical superiority issues in ASW hang in the balance. As such, initial customers are intended to be PMA-264 and PMA-290 programs. Since the research is targeted towards displays, this topic could be used to aid battlefield assessment, war gaming, and radar systems.

Title:Wavelet Compressions to Increase Desktop Personal Computer (PC) Real-Time Texture and Terrain Paging
Abstract:LNK Corporation, Inc., in conjunction with JRM Enterprises, Inc. and MultiGen, proposes to develop a wavelet compression library which will be able to support Open GL and Direct 3D rendering on commercially available low cost PC boards. This library will extend LNK's existing wavelet compression algorithms, which have been used to compress hyperspectral sensor data, digital elevation models, and image files which may be used as texture maps. The library will also support material based classification and region of interest definition, used in sensor simulation. While lossless compression of 2:1 can be readily achieved, the LNK Team will explore hardware-specific optimization and scene fidelity tradeoffs that permit order-of-magnitude improvements in compression ratio, enabling multiresolution mip-mapped terrain databases to be rendered at frame rates appropriate to tactical aircraft simulation. In Phase I, LNK will develop an experimentation testbed based on a PC platform using commercially available runtime APIs to explore database paging, system architecture, and software design approaches, collect metrics on perceived and positional accuracy of rendered databases, and identify likely NAVAIR systems and programs for Phase II development, testing, and utilization. The technologies to be developed as part of this effort have very broad commercial application, and the availability of real-time graphics and advanced networking connectivity in PC and desktop environments creates a wonderful array of new possibilities for commercial product development, especially in the education and training, and commercial gaming markets. The collaboration capabilities to be developed under this Phase I effort go far beyond currently existing collaborative design and learning tools, and represent the next wave of distributed desktop software environments which take advantage of emerging DoD practices such as the DMSO High Level Architecture. Our product goal is to create software products and services which facilitate both DoD and other desktop customer needs for interactive collaborative environments.

Title:Wavelet Compressions to Increase Desktop Personal Computer (PC) Real-Time Texture and Terrain Paging
Abstract:Increased use of aerial photography and satellite imagery in visual simulation has created problems for low-cost PC based systems. Although the performance of low-cost graphics systems is adequate for real-time interactive visualization tasks, the immense disk and memory configurations to support image-based databases are a major cost and technological obstruction. This proposal will investigate wavelet compression/decompression in a database paging scheme for real-time applications with potential for this capability to be hardware accelerated in Phase II. TERREX has already developed and successfully commercialized database generation software (Terra Vista) and a run-time paging format (TerraPage) which it proposes to extend through this SBIR contract. Our proposal is innovative as it a) promotes a multi-vendor runtime solution with open-source, public domain APIs, b) the solution is backed up by a commercially successful database generation system, and c) the proposed applications include much larger markets such as PC games and Geographic Information systems which will give this development effort a much stronger potential to be adapted to hardware and commercialized in later phases. TERREX has technical expertise and existing commercial products highly complementary to this SBIR topic. The company has an outstanding record of developing commercial software products for real-time interactive 3D simulation. The Phase I research will provide an initial design for a wavelet compression scheme tied to a paging system for run-time applications. A prototype system will be implemented and demonstrated at the end of Phase I by extending TERREX' existing commercial database generation software and paging format/APIs. This demonstration capability should provide quantifiable results on the technical viability of the wavelet compression scheme, any issues/problems related to its use in real-time 3D applications, and an assesment of its further potential development as a hardware accelerated compression/decompression engine in Phase II and Phase III of the project. Potential post applications for the wavelet compression technology proposed herein lie in any field in which large 3D datasets are combined with high-resolution imagery in a real-time, interactive environment. This most clearly affects the Modeling and Simulation community, the Geographic Information Systems (GIS) community, and in Computer Game Software. Wavelet compression promises image size reduction which will dramatically affect the amount and quality of imagery which can be used on interactive PC based visual applications.

Title:Compact Infrared Countermeasure (IRCM) Jam Head
Abstract:Tactical aircraft DIRCM systems require a compact, high-power laser source in the mid-IR band. Current IRCM lasers are costly and exceed weight, space and power constraints of Navy tactical aircraft. Phase I will conduct the necessary analyses and investigations to confirm the utility of the Lockheed Martin mid﷓IR semiconductor compact laser subsystem and commercial off the shelf CCD sensors and gimbals to fulfill this critical role. The various subsystems which comprise this solution will be integrated on a single optical bench requiring only a two-axis gimbal. Proof of concept will include atmospheric propagation analysis to define optimum lasing wavelengths and ensure sufficient J/S in real-life environments. LOWTRAN 7 and/or HITRAN atmospheric propagation models will be used to run the appropriate simulations. Additionally, overall system hardware and software requirements will be defined and preliminary real estate analyses will be conducted to verify the feasibility of integrating the miniaturized IRCM into the existing USN AGILE EYE jam head. The miniaturized IR countermeasure system that is the subject of this Phase I SBIR will provide low cost, onboard protection for a variety of defense and civil airborne platforms. Beyond the obvious protection of fixed and rotary wing military assets, the MIRCM is applicable to antiterrorist assets, coastal reconnaissance aircraft, and governmental and personal aircraft flying in high-risk areas worldwide.

Title:Infrared Countermeasures with Electronic Beam Scanning
Abstract:An innovative concept for a fast, efficient, high-resolution near-to-mid infrared beam scanner is proposed. Existing scanners, either mechanical (swinging mirror), electro-optic, liquid crystal, or acousto-optic, have certain limitations, and none of them satisfies military requirements for speed, resolution, range, effectiveness, and reliability. To overcome existing limitations, Physical Optics Corporation (POC) proposes to utilize the exceptional magneto-optic and magneto-elastic qualities of a certain class of metallic oxides. These qualities will lead to the excitation of a dynamic grating of local magnetic moments by propagating in the material an acoustic wave, and electronically tuning the spatial period of that grating by altering either the acoustic wavelength or the applied DC magnetic field. Thus, for the first time, two independent methods of beam scanning will be applied in a single element. In Phase I, POC will demonstrate the effective diffraction of infrared radiation on a magnetic grating induced by acoustic waves and wideband steering of the angle of diffraction by tuning of the driving (the piezotransducer) RF frequency and/or variation of the applied magnetic field. In addition to jamming, immediate military applications of the proposed scanner include missile seekers, target recognition, reconnaissance, and surveillance. POC's approach has the potential to reduce the size and power consumption of airborne and space-based jamming/tracking systems. Commercial applications include remote sensing, security systems, and switches for fiber-optic communication links.

Title:Solid-State Imaging Array for Laser Radar Applications
Abstract:This is a proposal for a very compact, low-power, High Range-resolution, Laser Radar (HRLR). The proposed preliminary design meets the solicitation requirements, namely a 5x 5 solid-state-array detector hybridized to a 5 x 5, 25-um pitch unit cell readout array. The readout array has the capability of 7.5-cm range resolution. Return-time data is multiplexed off the readout and only one output is required. Three options that could increase the performance of the 3-D imaging ladar system are suggested. The Phase I effort will include trade studies to optimize the sensor, the readout and the drive and output electronics. The readout will be designed and laid out in Phase I. The proposed $30,000, optional program includes the fabrication and performance-verification testing of the 5 x 5 readout array. Military applications of the HRLR imaging system and their civilian counterparts are in surveillance. There is also civilian application at airports - in support of safe takeoffs and landings - in robotic vision and in manufacturing. Radar does not have the resolution that could be achieved with a laser system. It is also quite possible that laser radar 3-D imaging systems will be used in future motor vehicles; penetration of small-particle fog is better at 1.55 um than at visible wavelengths.

Title:Solid State Imaging Array for Laser Radar Applications
Abstract:Sensors Unlimited will develop and deliver a 5x5 InGaAs avalanche photodiode (APD) array for use in eye-safe laser rangefinders. The avalanche photodiodes will be fabricated using a process virtually identical to our current production focal plane array process. Thus, the reliable operation of the arrays will be assured. The InGaAs APDs will have primary dark currents below 1 nA, avalanche gains in excess of 20, responsivity >15A/W at a wavelength of 1.55 m, and electrical bandwidths >2GHz. In Phase I the APDs will be fabricated in a 5x5 array and bump-bonded to a Si fanout for APD characterization. The final deliverable in Phase I will be a packaged 5x5 array with access to the 25 array elements via package pins. In Phase II, we will develop a readout circuit using small cell GaAs transimpedence amplifiers with scalability to arrays as large as 64x64 elements. The larger APD arrays will be hybridized to the readout ICs using our flip-chip indium bump process. In addition to the utility of InGaAs APD arrays in laser radar systems, there is a tremendous opportunity for commercialization of linear arrays of APDs in the field of fiber optic telecommunications. Currently deployed Dense Wavelength Division Multiplexed (DWDM) systems operate in the wavelength band of 1.530 m - 1.565 m and use single element InGaAs p-i-n and APD based receivers. The ability to manufacture large arrays of receivers is ideal for such systems, as the benefits of reduced power consumption, reduction of interconnections, and reduced electrical parasitics are easily realized in hybrid integrated systems. The advantage of APDs over p-i-ns is the same in telecom as it is in LADAR: an improvement in the sensitivity of the optical receiver. The amplifier architecture developed within this program is directly applicable to use in DWDM systems in linear array devices.

Title:Obsolete Electronic Parts Automated Functional Replacement System
Abstract:EDAptive Computing, Inc. (EDAptive), and Dr. Perry Alexander of the University of Kansas present a unique and commercially viable solution to the problem of automatically replacing obsolete legacy boards in weapon systems. Our Electronic Design Automation tools for Electronic Parts Obsolescence (EDA4EPO) program will apply an innovative and integrated collection of several Electronic Design Automation (EDA) tools and languages, under development, to the problem of Electronic Parts Obsolescence (EPO). Specifically, we propose to research and develop an iterative solution, which will employ three key emerging and essential technologies for automation in the future, namely (1) the industry-, academia-, and government-sponsored Rosetta, an emerging standard System Level Design Language (SLDL) for specification of obsolete boards, (2) the Defense Advanced Research Projects Agency (DARPA)-sponsored, EDAptive SOCCER tool suite for specification-based search and retrieval of functionally equivalent parts, and (3) the Air Force (AF)-sponsored Design Verification Test Generation (DVTG) tool to validate board specification in Rosetta as well as SOCCER-generated, functionally-equivalent boards. We have discussed our technical and commercialization approach with potential customers and partners have found endorsement and early support for it among them. Maturation and integration of tools and languages proposed under this effort will alleviate the electronics parts obsolescence problem and reduce the cost of addressing it by at least an order of magnitude. In addition to DoD applications, the proposed system could be used for sustainment and post-production support of any electronic system, as well semi-automated synthesis of electronic systems starting with a formal specification.

Title:Automated Functional Replacement (AFR) of Obsolete Parts Through Virtual Prototyping: A Study.
Abstract:VP Technologies, Inc., is currently a contractor on the USAF Electronics Parts Obsolescence Initiative (EPOI, 1998-2001) and has also been selected a tier 1 subcontractor by Lockheed Martin (E&M, Orlando, FL) for its AMCE Parts Obsolescence (PO) Pilot Programs (JASSM & LOCAAS, 2000-2002). We are thus able to apply our extensive experience in combating electronics parts obsolescence at chip and board/subsystem levels, and also to leverage our partnerships with leading defense contractors, to develop a comprehensive solution to the problem of automated functional replacement (AFR) of obsolete parts. An innovative approach based on virtual prototyping technologies is proposed as part of this SBIR Phase I effort. The AFR system as proposed consists of three components: (1) A legacy design intent extractor that generates executable specifications and test vectors of the obsolete part from partial or incomplete legacy data using syntactic and semantic recovery algorithms, (2) An architectural tradeoff environment that selects the right implementation for the replacement parts based on form/fit/functional constraints, and (3) A detailed SW/HW design synthesis component that generates the functional replacement for the obsolete part together with its test vectors. Our approach is further characterized by its board-level replacement methodology, as opposed to traditional chip-by-chip replacement methodologies. A detailed benefit/cost analysis of the proposed approach will be completed in Phase I, together with a comparison to "hardware-in-loop" driven current practice, as applied to weapons systems. The proposed virtual prototyping approach to automated functional replacement (AFR) has immediate applications in the parts obsolescence management problems of the defense and avionics industries (a multi-billion dollar market). As lifecycles of various systems become longer, the problem has become particularly severe resulting in the need for new and powerful technologies as outlined in our technical proposal on this SBIR effort. With decreasing times to market in the commercial world (e.g., 3 months in the telecommunications arena), commercial electronic products require continuous upgrades of systems to include newer technologies and components (thus creating a problem analogous to parts obsolescence in the defense industry). The proposed obsolescence management and upgrade technologies developed as part of this SBIR proposal can be directly applied to commercial electronics products in telecom, embedded computing systems, and information appliance markets - a potential trillion dollar arena. The proposed algorithms, tool suites, and component model libraries that are proposed will facilitate rapid system-level design, upgrade, and test, promising a "model-year" approach to electronics system design, spanning digital, analog, and RF domains.

Title:Nitrogen Charging System for the Advanced Amphibious Assault Vehicle (AAAV)
Abstract:CME will develop an efficient, light weight, high-pressure nitrogen gas charging system that shall be designed for field deployment on the Marine Corps new Advanced Amphibious Assault Vehicle (AAAV). CME will perform trade studies and work with COTS suppliers along with designing custom components to meet the performance, size, weight, and cost objectives. CME's approach and proven experience associated with high-pressure gas systems will facilitate the design of a small lightweight gas charging system that will allow field maintenance operations on the 7000 psi Hydro-pneumatic Suspension Units (HSU's'). The system target weight of 87 pounds is achievable using the AAAV's existing power sources for motivation while still maintaining identified safety margins associated with high- pressure gas systems. CME will apply COTS hardware where applicable to enhance manufacturability, maintainability, and minimal cost impact. CME will apply computer simulations to determine and document overall system performance. During the Option, we will develop final detailed drawing packages in preparation for Phase II. The manufacturer and test of three prototype charging systems will be conducted during Phase II activities. With a final design for a small high-pressure gas charging system, a reliable field-deployable system can be manufactured for the military and commercial markets that need high-pressure gas suspension for field charging of their systems, while also improving the prevention of oxidization/corrosion of internal suspension components. Phase III manufacturing and marketing planning will prepare the nitrogen charging system design for full-scale commercial product launch and entry into related market segments such as auto racing, medium to heavy truck transports, heavy construction equipment, aviation, etc.

Title:Lightweight, 1kW Portable Multi-Fuel Generator (PMFG)
Abstract:The development of a lightweight, portable, multi-fuel generator set with output in the 1 kW range is proposed. The development shall be based on the innovative integration of three enabling technologies that have been realized in recent years. These are: (1) conversion of lightweight, high rpm two-stroke gasoline engines to operate with multi-fuel; (2) high power density, permanent-magnet, axial-gap modular alternator design; and (3) digital, solid-date electronics power conditioning. Each of these technologies has been validated by the proposing team in different arenas to assure the prospect for optimum integration and near-term realization of the overall objective of the project. Phase I effort shall be concerned with the development of concepts and hardware implementation for optimum integration of these technologies leading to a technology feasibility demonstration unit that can meet the weight and output power performance specifications. During the Phase I Option, the design shall be further refined to render the design "Marine Ready" for prototype development under Phase II. It is anticipated that such a lightweight, portable multi-fuel generator (PMFG) unit will also have significant demand in the commercial market for recreational, industrial and home use to meet the multiple objectives of the SBIR program. The realization of small, lightweight, multi-fuel capable generators will significantly enhance the mobility and C4I operational capability of small detachments of Marines on the battlefield. Such units also have demand in the commercial sector for recreational, industrial and home use.

Title:Demonstration of a 40 Pound Miniature Electrical Generator Which Uses a Lightweight, Quiet, Compact, Multi-Fuel Engine
Abstract:Desert Storm indicated that portable lightweight miniature electrical generators are needed for combat field operations. Mainstream has previously developed a JP-8 (multi-fuel) 53 pound 1kW portable diesel electrical generator under a prior Army BAA effort. This Phase I will extend this development effort to demonstrate that based on the results of this earlier hardware development and additional IR&D by Mainstream we feel confident that we can demonstrate a 1 kW unit with a system weight below 40 pounds. This Phase I effort will demonstrate the performance of a prototype system. The proposed effort includes the detailed redesign and fabrication of selected components of Mainstream's existing 53 pound multi-fuel 1 kW diesel generator to provide a demonstration unit which weighs less than 40 pounds. The generator will be configured as a portable unit for easy carrying to the point of use, where it could be set-up to provide continuous, relatively-quiet electrical power. The Phase I will demonstrate the Mainstream's unit meets the Navy's performance, weight, size, fuel economy, reliability, maintainability, and noise requirements. Phase II will include a further refinements and deliverable of prototype units for extensive field tests. This Phase I effort will demonstrate an innovative, compact multi-fuel diesel generator that has tremendous marine, disaster relief, and industrial niche market applications where the safety and stability of diesel fuel over gasoline represents a significant advantage. Mainstream has already committed it own resources and secured a commercialization partner. Our marketing studies have indicated a substantial marine and disaster relief niche market.

Title:A Low-Profile Tagging System for Locating Personnel and Material
Abstract:We propose to develop a remotely deliverable tagging device for both marking and tracking personnel, material, and vehicles. The approach is based on a new radiolocation technique we have developed, which is capable of highly accurate location determination using simple tag electronics. The research goals are to determine how small the device can be made using current electronic and battery technology, to identify delivery techniques capable of deploying the tag from a distance of 50 meters or more, to design low-cost portable base stations for receiving tag signals and determining location, and to study techniques to enhance performance in urban multipath. The system intelligence is contained in low-cost portable receiving/tracking stations that can track the target either stand-alone or collaboratively, as needed. The proposed system will be a major enhancement over our technology developed for applications such as locating patients with Alzheimer's disease and tracking cargo. In previous research the receiver stations were fixed 5 miles apart, and the tag, which did not need to be concealed, was too large for the application proposed here. In Phase II we plan the to implement the miniaturized tag, to refine the delivery concept, and to follow up with field testing with prototype receiving stations. The proposed technology would allow covert tracking and locating of people and valuable material or cargo with high accuracy. It has applications in less-than-lethal warfare and monitoring and locating stolen weapons, tracking cargo and packages, and locating stolen goods.

Title:Resin-Transmitter for Covert, Non-Lethal Tagging
Abstract:Triton Systems responds to the Navy need to covertly and non- lethally tag personnel and/or equipment, at a range of 50 m to 500 m, and to obtain a later return signal at 1 km. The Triton response to this need is to develop its own unique shelf-stable resin-transmitter, using COTS parts. The stable resin contains a micro-transmitter with the required size and range, that will be delivered by a tethered or retarded projectile, allowing the resin-transmitter to separate from the projectile and to be covertly adhered to clothing or equipment as a final stable plastic tag. On the Phase I program, Triton will fabricate the stable resin-transmitter; will demonstrate its separation from a model tethered or retarded projectile, and the formation of a stable adhesive plastic tag. On the Phase I Option, Triton will demonstrate the delivery of a stable tag to clothing and/or equipment at short range, using a simulated tethered projectile traveling at 250 ft/sec, with a return readout of 50 to 100 m. On Phase II, with a ballistics partner, Triton will develop a realistic projectile resin-transmitter delivery system; with separation and delivery of a tag at 50 to 100 m at gun velocity, with a return signal at 1 km. On Phase III, Triton will work with a munitions / arms maker to make a prototype tag delivery system. If the proposed technology is successful, field commanders will have the ability to covertly and non-lethally tag personnel and equipment when conducting military operations in urban terrain (MOUT) and other areas where immediate action is not appropriate. Such a technology also is of intense interest to civilian police organizations worldwide. It would permit them to covertly and non-lethally mark and track vehicles and hostile elements that blend in with the local population of uninvolved citizens. The commercial market for this technology is large.

Title:Handheld Autonomous MEMS Based Navigation/Communication/Tracking System
Abstract:The objective of this SBIR Phase I project is to design, fabricate, and evaluate a low cost, small size, lightweight, handheld, autonomous navigator with wireless communication, map display, and tracking capability. The current position location tracking systems relay on the reception of GPS radio frequency (RF) signals to obtain position information, which prohibits it's use in urbanized terrain environments. Recently, MEMS (MicroElectronicMechanicalSystem) technologies make it possible to fabricate the monolithic integration of MEMS inertial and magnetic sensors with driving, signal pickoff, and signal processing electronics, which offer tremendous cost, size, reliability improvements, compared with conventional inertial sensors. Advanced MMIC technology (Microwave Monolithic IC) can shrink conventional radar into a chip. In this project, the innovative navigator utilizes an American GNC corporation developed commercial product, coremicroTM IMU based on state-of- the-art multiple MEMS sensors and unique ASIC (Application Specific Integrated Circuit) design, tiny magnetic heading sensor, a tiny Doppler radar, and patented filtering technology to achieve high precision navigation accuracy independent of GPS signals for the navigation/communication/tracking system. This Handheld Autonomous MEMS Navigation/Communication/Tracking System will find a large market in the military and civilian sectors. Typical applications will be founded in the areas where GPS signals are not continuously available, such as inside buildings, tunnels, forested areas, urbanized terrain, and high Electronic Counter Measure (ECM) environments.

Title:Multiple-Personnel Tracking System Using Uniquely Coded RF Tags
Abstract:We propose that an RF-based personnel tracking system has significant advantages over presently used or contemplated ultrasonic/GPS systems. The proposed RF tracking system uses a central tracking station and multiple RF receivers to sense signals from personnel mounted transponder tags. The tags respond to uniquely coded probe signals by transmitting a second set of time coded RF signals. Triangulation to the receivers using proprietary signal processing algorithms allows accurate location of the tags in 2 and 3 dimensions. Numerical simulations of the algorithms indicate highly accurate distance measurement capability even under very low signal conditions and in the presence of RF reflective objects. The proposed system can seamlessly be interfaced with existing GPS systems to eliminate the tracking loss problem during building entry/exit. Furthemore, the system could also be extended to km distance scales for full coverage of training ranges. Such extensions could eliminate the need for GPS entirely, leading to a lower system cost. In Phase I we plan to develop and build a simple RF system to demonstrate tracking of at least one person. We will also refine the processor algorithms with a view to extending operating range and maximizing spatial resolution under low signal and multipath conditions. The proposed systems has applicability to fire fighter accountability systems, as well as location and tracking of inventories, equipment, and persons in secure facilities and prisons

Title:Advanced Wearable Computer Interface for UGV Control
Abstract:With recent advances in wearable computing and associated control and display mechanisms, there is significant opportunity to create a more effective operator control system for unmanned ground vehicle (UGV) operations. This Phase I effort proposes to study the UGV control problem, evaluate the advanced technology options for creation of a wearable control system, and design an optimum solution. Cybernet has significant experience to leverage in the development of advanced human computer interfaces, and in the development of portable UGV control systems. Advanced technology options that will be evaluated include: 1) hands-free interface solutions, such as voice recognition, eye tracking, gesture control, etc., 2) miniature force-feedback and other haptic devices, and 3) immersive and head-mounted displays. Selection of the advanced interface technologies will be performed based on satisfaction of the UGV control operation requirements, feasibility of implementation within a wearable computing platform, cost, potential benefit, associated risk, etc. The result of this Phase I effort will be the design of a highly intuitive and effective wearable computer interface for UGV operation, incorporating advanced control and display technologies. The immediate commercialization potential is for a wide range of military and other UGV control applications. The developed wearable operator control interface technology will also have broad reaching commercial potential for many other military and industrial control applications.

Title:Precision Sea-Based Logistics System
Abstract:Significant problems face the USMC as it plans its precision logistics pipelines for Advanced Amphibious Assault Vehicles (AAAV). The USMC now relies on inefficient, manual processes, primitive decision aids, and "time-late" communications in its legacy logistics efforts to support mobile warfighting platforms. An innovative Precision Sea Based Logistics System (PSBLS) - for AAAVs and other USMC mobile units - will address those problems with enhanced logistics velocity, visibility, and variability for Ship to Objective Maneuver. A robust PSBLS solution will embody intelligent agents, capable user interfaces, web-centric applications, plus open-systems interfaces to "operate in such a way that commanders have absolute confidence that required support will be provided when and where it is needed." General James Jones, Commandant ORINCON's team will develop, test, and integrate cost-effective information technologies to automate, monitor, and recommend actions for the USMC precision logistics system. We plan to "instrument the pipeline" from factory to deployed units with automated tracking, cost accounting, prognostic evaluation, and total asset visibility. Our unique technical and operational experience will be leveraged to provide a comprehensive Performance Specification, a Decision Support System design, and a Cost Benefit Analysis for this innovative USMC AAAV logistics program. o The USMC and its AAAV organization will directly benefit from this system's innovative decision support, centralized computers/applications and human-factored total asset visibility (TAV). o Commercial merit of our feasibility study extends to focused logistics systems of all armed services and the DLA. Resultant PSBLS functions can further transition to commercial "just in time" high-volume logistics support systems that are multi-million dollar efforts annually. o Boeing Aircraft Company expressed initial interest in some of our intelligent agents for maintenance support of commercial aircraft systems

Title:Precision Sea-Based Logistics
Abstract:Successful supply-chain management is an essential element in high performance military environments. Rapid delivery of key items to deployed mobile units is a must for military strategists. Effective logistics/supply-chain management allows just-in-time distribution of goods and services. Current technologies are available to evaluate inventory levels across the supply chain. The use of the World Wide Web allows faster flow-through times in supply chain pipelines. Many commercial and military organizations are feeling an urgent need to integrate an extended enterprise logistics system. USMC 's Precision Sea-Based Logistics is a human-factored, computerized system that requires Total Asset Visibility (TAV) of spare parts, issuance of repair notifications, tracking of maintenance history, and cost. USMC plans to deploy a sea-based logistics system. TPI proposes to develop a centralized information logistics system that is based on a fully extended enterprise model. This Precision Sea-Based Logistics (PSL) system will assist in information flow between components of USMC's sea-based physical logistics system. The PSL system will maintain the Total Asset Visibility (TAV) in a centralized database, which will include configuration management and maintenance history and is capable of wire or wireless communication with the mobile vehicles and maintenance facility. TPI believes that the proposed system once implemented would bring US Marines Corps logistics/supply-chain management capabilities into the next decade. It will support the N/MC Intranet structure. USMC is planning to build the N/MCI in the next five years that could be used for global application of the Precision Sea-Based Logistics (PSL) system. Furthermore, the proposed PSL system will assist USMC in achieving its goal of moving the logistics to a sea-based system. There are many direct benefits to USMC and among them are reduced inventory, effective logistics management and on time delivery to the mobile vehicles. General Dynamics Amphibious System (GDAMS) is building Advanced Amphibious Assault Vehicle (AAAV) for the United States Marine Corp. The proposed system can directly be used for AAAV logistics. The PSL system is capable of supporting trucking industry whether or not a truck is near its desired maintenance facility. A mobile truck may be able to quickly report to the base via PSL system its maintenance problems and parts requirements. TPI is planning to approach many Logistics companies once the system is built. Among them are United States Truck Stop Association, United Parcel Services, Federal Express, and others.

Title:Link-16 Enhanced Positional Accuracy for Precision Guidance
Abstract:This SBIR seeks to exploit the inherent synchronization and RELNAV capability of the communication links in network-centric architectures to complement or replace the GPS solutions. Avtec proposes to develop a software solution exploiting the inherent capabilities of Link-16 which is incorporated in most network-centric tactical architectures. Avtec's approach will explore algorithms based on a technique described and patented by the proposed Principal Investigator. Avtec's approach can be applied to any two-way digital link. In Phase I, Avtec will (1) identify optimized Link-16 configuration(s) for synchronization and range measurement using the Round Trip Timing (RTT) feature, and (2) design and evaluate algorithm(s) for merged synchronization and RELNAV using measurements from Link-16 and a representative GPS system. We anticipate that work in this SBIR will lead to future activities related to Link-16 and GPS for network-centric architectures. In addition we see the techniques to be investigated in this SBIR being applied beyond the Link-16 environment.

Title:High Frequency Transmit Mast Clamp Current Probe
Abstract:Fischer Custom Communications, Inc. proposes to determine the types of magnetic core materials required to design and fabricate a current injection transformer capable of exciting various parts of a ships superstructure to act as a transmit antenna in the 2 MHz to 30 MHz frequency range. Conventional high frequency shipboard antennas occupy substantial volume, making them difficult to site on the ship without interfering with ship operations. Conventional anntennas have high maintenance and have a significant and distinct radar cross section. A current injection transformer is virtually maintenance free and would replace existing transmit antennas. By using the existing ship structure as an antenna, the current injection transformer provides HF communication and eliminates adverse operations, maintenance and RCS impact of conventional antennas. In Phase I the appropriate magnetic core materials will be determined and feasibility of the current injection transformer will be demonstrated Conventional high frequency shipboard antennas are difficult to site on the ship without interfering with ship operations, have high maintenance and a significant radar cross section. The transmit mast current probe is virtually maintenance free, has a significantly lower radar cross section and would replace the exisitng transmit antennas. The price of a transmit mast probe will be significantly less than the conventional shipboard HF communication antenna. The annual maintenance cost of the transmit mast probe will be a fraction of the conventional HF transmit antenna. Commercial applications include industrial and recreational maritime communications as well as other industrial and recreational HF communications systems.

Title:Intelligent Jammer Placement Tool
Abstract:The Navy would like to deny GPS-based or other satellite-based navigation to an enemy in times of conflict, and one of the most practical means of doing so is via jamming. However, it is very important to control where the jamming energy is directed so that friendly receivers are minimally affected. This proposal describes Toyon Research's plan to develop a PC-based optimization toolbox to solve the Navy's jammer placement problem and deliver a prototype version in Phase I. Rather than relying on a single optimization algorithm, the toolbox will include several such tools and a flexible means of controlling their application. Built into the toolbox will be smart features to speed up the optimization process and a means of "learning" from the users' experience in different applications. The toolbox will also provide solutions to the problem of mission planning to avoid jamming and will include an easy-to-use graphical user interface. The development will result in a computer tool to simplify the process of deploying jammers which in turn improve the Navy's warfighting capability and increase the fleet's survivability.

Title:Wireless Line-of-Sight Networks for IntraBattlegroup Communications
Abstract:The U.S. Navy is in need of a means for high data rate (HDR) line-of-sight (LOS) communications between its ships, submarines, and shore sites. The total point-to-point intra-battlegroup capacity currently available is less than 268 kbps per ship. This capacity was marginally adequate several years ago, but the increase in traffic load offered by available government off-the-shelf (GOTS) and commercial off-the-shelf (COTS) systems has resulted in requirements for wideband, high spectral efficiency, wireless mobile networks. The Navy is in the process of procuring a software defined radio (SDR), named the Digital Modular Radio (DMR), which addresses issues related to legacy support and hardware development costs. Therefore, an established SDR in the form of DMR addresses the legacy requirements and significantly reduces development costs - the remaining problem is defining a reliable wideband technology. During the HDR LOS BAA, Nova has implemented a spectrally efficient, wideband, wireless waveform that supports heterogeneous mesh networking. The waveform is designed to be resistant to channel impairments commonly encountered in the Navy's signaling environment. The results of this SBIR, titled Wideband IntraBattlegroup Communications (WIC), will add up to 4.608 Mbps of reliable, adaptive multiuser wireless network capacity to each ship within a battlegroup. Both the military and commercial sector have a tremendous demand for more signaling bandwidth. The HDR LOS waveform offers a substantial increase in terrestrial capacity over a diverse set of distances and in the presence of channel impairments such as dynamic multipath.

Title:Wireless Line-of-Sight Networks for IntraBattlegroup Communications
Abstract:Important issues in military networking are more bandwidth, decreased complexity for the operators, increased reliability and the migration to IP-based services. These issues require novel solutions because military tactical networks typically lack centralized infrastructures like cellular networks. In addition, military wireless networks often have lower bandwidths, higher error-rates, and lesser-trained operators than commercial ones. SRC proposes to develop additional capability that enhances the DoD's planned software-defined tactical radio systems, such as Digital Module Radio (DMR) and Joint Tactical Radio System (JTRS). These capabilities will include: a) advanced routing and multicasting capabilities optimized for tactical environments; b) link-layer retransmission functionality designed for high error-rate wireless links; c) differentiated QoS across the low data-rate wireless links; and d) a high performance wireless link for Unmanned Aerial Vehicles. These capabilities will be added as "middleware", "shim software" or reconfigurable hardware units, which will allow incremental deployment of these new features without modifying the existing application software, TCP/IP stacks or radios. Since SRC already has technical solutions for these problems, this Phase 1 will examine the suitability of these solutions to Navy battle group applications, and develop a practical implementation approach within the confines of the DMR and JTRS architectures. The Phase 2 prototype will contribute significantly to the definition of next-generation military tactical radio by enabling real-time, multimedia services within DoD tactical Intranets. From a Navy standpoint, the integration of IP-based voice, video and data from the various on-ship networks, the DoD Internet backbone and the airborne reconnaissance assets will provide a fused operational picture that maximizes the protective shield around the fleet assets and their personnel. Tighter integration with deployed on-shore networks allows more focused use of the Navy shipborne and airborne ordinance, and hence a greater force multiplier for those expensive assets and their highly trained operators. More generically, applications such as IP to military aircraft and IP to the Army HMMWV will also benefit from this approach. Finally, the software could be ported to handheld, battery-operated terminals carried by each soldier. In the future, this will enable both Personal Area Networks (PANs) and Squad Area Networks (SANs) between soldiers and their associated sensor network(s), in order to bring "information dominance" down to the "foxhole level". Target COTS technologies include cellular telephony, IEEE 802.11 Wireless Local Area Networks (WLANs) and Bluetooth. Commercial applications include users operating without existing infrastructures such as office workers in old buildings, warehouse workers, and emergency operations such as police, fire and emergency health care.

Title:Sensor Tasking Segment (STS)
Abstract:An innovative network centric Sensor Tasking architecture will be develop using thin Tasking Clients, Server Application, and Sensor Agents for Information Warfare sensor tasking and management. The Sensor Tasking Segment (STS) will use a wide area distributed network based on JAVA virtual machine object interaction. During Phase I, the collaborative software modules and agent interfaces will be defined. The Tasking Server will use schemas of mission plans, collection objectives, reporting requirements, signal of interest definitions, and dynamic sensor resource descriptions to create a collaborative tasking environment. STS interaction will be investigated for performance, cost and risk in developing tasking strategies compliant with the Maritime Cryptologic Architecture (MCA) as well standards to become a GCCS-M/CUB segment. A Phase I Option is proposed to extend Client/Server/Agent interaction by designing "bootstrap" tasking. This will allow Sensor Agents to survey the RF environment beyond specified tasking and let the Server recommend to Tasking Clients new signals of interest and collection opportunities that may enhance current mission requirements and tasking plans. It is envisioned that during Phase II, a wide area distributed network STS will be demonstrated with at least one sensor system and a set of distributed Tasking Clients, each with different mission requirements. We envision multiple opportunities for commercializing the software products that are developed under this SBIR. The immediate opportunities for commercialization involve other government agencies that have similar problems with managing electronic intelligence activities. By adhering to the JTA/DII COE model we will be able to tasking applications and tool sets to other member of the Department of Defense community for integration with existing and future systems. Using object oriented architectures such as the Common Object Request Broker Architecture (CORBA) along with object oriented programming languages such as JAVA will enable our company to package the tools and applications developed under this SBIR into utilities that can be used outside the electronic intelligence arena. CORBA provides an open standard for defining reusable objects in distributed heterogeneous computer systems.

Title:Distributed Expert-Agent and Object-Oriented Framework for Anomaly Detection
Abstract:Current state of the art commercial intrusion detection systems have concentrated mostly on string matching and other forms of signature identification to detect anomalies and outside attacks. In the research community at large, advances have slowed, with increased emphasis on detecting known types of outside attacks. Detecting, identifying and responding to hitherto unknown attacks and anomalies remains a challenging problem. Further, it has been demonstrably established that no single approach is capable of detecting and diagnosing all the anomalies that can occur in a complex and challenging environment such as a hybrid heterogeneous network. ATC proposes a innovative distributed agent framework, populated by expert agents that will detect network faults which occur during routine operations and due to malicious activity. By abstracting the common functionalities of existing anomaly detection techniques and developing a framework for distributed computing and data sharing, problems of limited resource on wireless nodes and obsolescence of detection techniques are addressed. Also, by flagging an anomaly only when the majority of the agents involved in fault detection reach a consensus, the number of false alarms is decreased and robustness increases. The framework will be published as a RFC at IETF and the software will be published through appropriate sources. Early adopters will be equipment vendors, system integrators and system maintenance personnel to optimize automated fault tolerance procedures in network environments.

Title:Trusted Workstation Using a Plug-in Encryption Module
Abstract:Current CMW workstations have been developed by providing a hardened UNIX operating system for COTS workstations. Under the Navy's 21st Century Information Technology (IT21) initiative, there is a push to try to provide commonality among operating systems, operating environments, and networking to ensure interoperability. This has required many tactical and administrative applications to be ported to a Windows NT operating environment. The porting of these applications has been completed in many cases. However, the Windows NT operating system has its own issues. It is a proprietary operating system with closed source code. It would be extremely costly for the Government to try to provide B-1 level hardening to Windows NT. In addition, it would require testing to validate that the changes to the operating system did not create any changes in the way the operating system interacts with application programs. Therefore, a hardware solution is a feasible alternative and the operating system would remain largely intact as a Commercial Off The Shelf (COTS) solution. A hardware plug-in module provides the security for the COTS workstation with a Windows operating system. The RamPart technology is the solution, by providing secure startup and monitoring of the workstation. The potential of the RamPart system is enormous. RamPart was developed in response to a need that has never been able to be fulfilled before. Amron Corporation, with our knowledge of Navy Programs, sees a tremendous potential for Phase III applications both commercially and for the Government. NIPRNET to Internet Gateways, intrusion detection machines, SIPRNET machines, and operational workstations onboard Navy platforms all have a need for improved security on COTS. The US Government has identified Information Management Assurance and Distribution as a key technology area, adding to the emphasis that has already been placed on computer security. PCSEC, LLC and Amron Corporation are pursuing a coordinated teaming effort to apply this technology to a number of applications and evaluating the security of the system is a key to accomplishing the marketing strategy.

Title:Trusted Workstation Based on a COTS PC
Abstract:The Navy requires a trusted workstation equivalent to a B-1 Compartmented Mode Workstation (CMW) that can be built from a COTS PC. In response, Physical Optics Corporation (POC) proposes an innovative low cost approach to implementing a CMW using multiple Single Board Computers (SBC) and an integrated Intelligent Secure Access Control Switch all integrated on a passive PCI backplane. The POC approach will have the following benefits: significant cost savings by using COTS SBCs hardware, a COTS operating system (OS) and application software and a single network connection; a modular design providing the best information partitioning with different security levels; significantly improved CMW fault tolerance; significantly improved security against both external and internal threats; easily upgraded with next-generation COTS operating systems and COTS application software upgrades. Phase I evaluation will be done using normal certification processes under the guidance of a Navy Certification Agent (CA). Phase I efforts will focus on hardware/software prototype construction, testing and security evaluation. In Phase II POC will complete the hardware and software design and demonstrate superior security capabilities. POC's CMW has a great number of military and commercial applications. It can be used as a low-cost secure work station at any location that maintains classified data or programs. In addition, it can also be used by organizations or individuals who desire to operate multiple computers concurrently in a single work station with a single user interface.

The RFDS is capable of accommodating broadband signals distribution to allow spread spectrum and frequency hopping communications and counter-communications (IW) operations. It will also be compatable with all Legacy systems. The RFDS has great potential to be used in commercial applications for base stations and gateways for direct broadcast satellite TV, cell phone services, and PCS.

Title:High Precision Depolarized Fiber Optic Gyro (DFOG)
Abstract:We propose new techniques to reduce the degradation of the detected signal of a depolarized fiber gyroscope as a result of noise from the light source. Attempts have been made to reduce intensity noise in fiber gyroscopes that use polarization- maintaining fiber in the fiber coil. We will review the efficacy of these techniques and attempt to determine their theoretical limitations. In a depolarized fiber gyroscope, source phase noise is converted to intensity noise. This creates a noise that has not been addressed heretofore. We propose to examine techniques to also reduce this noise. The use of single-mode fiber in the sensing coil will significantly reduce the cost of the gyroscope by reducing the cost of the fiber in the sensing coils. The price of single-mode fiber is between 1/2 and 1/100 of the cost of polarization maintaining fiber. This has the largest impact on high performance fiber-optic gyroscopes where the length of the fiber in the fiber loop is large and the cost of the fiber is a large fraction of the cost of the gyroscope.

Title:Wireless Multi-Parameter Sensor Modules for Ordnance Monitoring
Abstract:Intelligent sensors and systems using microelectromechanical systems (MEMS) technologies for the health monitoring of energetic components are sought by the U.S. Navy Strategic Systems Program. To support the advancement of DoD initiatives in improved ordnance diagnostics, Intelligent Optical Systems (IOS) will develop a wireless multi-parameter sensor module for real-time, in-situ chemical and physical monitoring within energetic components. The IOS approach will use a novel MEMS-based microcantilever array, coupled with advanced spread-spectrum communications, to create a compact, low-power, embeddable multiparameter sensor suitable for use directly in and around energetic materials. In Phase I project we will fabricate unique low-voltage PZT thin-film resonant cantilever structures, and show that, with the use of selective coatings, these sensors can be used to detect propellant breakdown products (e.g., acetic acid). A complete engineering demonstration chip will be fabricated, including both resonant structures and microtelemetry electronics; the feasibility of our proposed approach will be conclusively shown in experiments where the sensor chips are exposed to know concentrations of target analyte. In Phase II, IOS will fabricate afield-ready launch tube gas generator-monitoring device and run systematic tests to evaluate system cost and reliability. After Phase II, the proposed wireless multiparameter sensor unit will be tested and commercialized with the help of a leading solid rocket motor manufacturer. The proposed technology could be used to make multi-element or multi-target sensor arrays involving hundreds of thin films and cantilevers without significantly increasing the size, complexity, or cost of an overall sensor package. The sensor module will find applications in warhead and rocket motor monitoring, weapon systems, and commercial chemical in manufacturing, storage, and transportation.

Title:Global Positioning Satellite (GPS) Receiver Test Bed
Abstract:We propose to develop a test bed to evaluate GPS performance on re-entry bodies. Available computational tools will be used to simulate those effects which potentially impact GPS operation including plasma sheathing, aerothermal heating, geometric shadowing and dynamics. Software will be developed to characterize these effects which will then be utilized to generate distorted signals which will be fed into the test GPS receiver. The test bed will allow hardware in the loop simulation of GPS performance under a variety of conditions. During the Phase I program we will define the test bed requirements, quantify the operational space, develop a conceptual design and demonstrate feasibility. The Phase I option will develop a preliminary test bed design and a Phase II program plan The availability of a GPS performance test bed will allow issues related to the guidance and navigation of high accuracy re-entry body designs to be evaluated in the laboratory prior to the implementation of expensive full scale field tests. Several DoD agencies should be interested in such a test bed and the strategies for overcoming re-entry guidance problems which we will evaluate. Derivative commercial applications are also thought to exist.

Title:Robotic Manipulator for Cargo/Weapons Handling
Abstract:It has been determined that manning is the largest cost component in Naval Operations. As a result, the Navy has mandated that crew size on future ship be reduced dramatically. Agile Systems Inc.believes an important opportunity exists across all classes of naval ships to employ employ advanced automation technology to replace sailors in what is perhaps the Navy's single most manpower-intensive process- the delivery of weapons and cargo from pierside warehouses, through a series of supply ships, to the point of use on a surface combatant. No automation system presently exists that meets Navy requirements. the program outlines herein addresses that problem, focussing on the development of a unique robotic pallet and container handling system with the load capacity, speed, and inventory managemant capabilities required to deliver both palletized and containerized cargo and weapons automatically, on demand, within the holds and on the decks of naval vessels. In Phase I, a design concept and specifications for the robotic handling system will be established. In Phase II, a small-scale prototype will be engineered, manufactured, and tested on the Navy's ship dynamics simulator. In Phase III full-scale versions of this system will be implemented for both Navy and industrial applications. *Flexible and reliable automated cargo and weapons handling systems for naval and commercial ships. *Elimonation of forklift trucks and conventional pallet movers and associated manpower. *Automation of palletized and containerized cargo handling in warehouses and factories *Applications in trucking and rail transport systems

Title:Tubular Manipulator Arm with High-Force Strain-Body Electric Actuators
Abstract:Proposed for development is a cargo/weapons handling system based on a family of large-force, small-stroke, high-stiffness electric actuators. The actuators may be combined in a variety of configurations for a wide range of load manipulation tasks. The ultimate implementation is in a set of manipulators based on a snake-like robot arm. They are tubular bodies with multi-jointed skeletons. The members and joints are placed to give the arm as many degrees of freedom in bending, extension, and rotation as are necessary for the task. The initial increment of the actuator family that is proposed to be developed in Phase 1 consists of an effector with and modest range of motion to be used between a weapon grabber and weapon-loading lift truck. The effector augments the four-bar linkage used to lift the weapon to a wing station. The augmentation allows the lift to translate, extend and rotate in an envelope of motion of approximately 4 inches. This capability eliminates much of the man-handling required to jostle a weapon into place and can replace the total man-loading of small weapons such as Sidewinder. It uses what are called strain-body actuators to change the shape of the relatively stiff links of the lift mechanism. This is a stepping stone to the design of a strain-body based 6000-lb capacity manipulator to serve a magazine-elevator. The actuator family proposed for development and its control software, are based on existing commercial products and offer a low-cost development path to a variety of weapon- and cargo-handling devices. These actuators and the manipulators which use them can reduce shipboard manning and can speed material handling processes to minimize replenishment evolutions and to increase on-station time of combatants. Commercial applications for such material handling equipment abound.

Title:An Electrorheologically Based Smart Filter for the Removal of Particulates and Water from Fuels
Abstract:In the future, aircraft carriers will be expected to achieve a sortie rate 50 percent greater than is currently attained. To achieve this increased capability a high fueling rate will be necessary. Fueling rates are currently constrained by the 2000 gpm limitation imposed by the fuel filters. Consequently, the Navy wishes to develop filtration systems that can deliver fuel at rates of up to 4000 gpm, while at the same time requiring that the advanced fuel filter be about half the size and weight of current systems. An important additional requirement is that the health risk associated with maintaining and replacing the cartridge elements on its current fuel filters be eliminated. Foster-Miller proposes evaluating a novel filter medium and innovative filtration technique as the basis for an advanced smart fuel filter that meets these target specifications. The filter medium is a conducting polymer and the filtration technique is electrorheologically (ER)-based. The Phase I program involves selecting the ER substrate, synthesizing the conducting polymer, and characterizing the filter medium. An Option program proposes building and testing a prototype filter. Foster-Miller has teamed with a fuel filter manufacturer to commercialize this product. (p00342) The small, high rate, regenerable filters that result from the advanced filter media will be suitable for treating all fuels used by the military. The performance and operational simplicity of the filters will make them attractive for use by commercial airlines and airports.

Title:A High Capacity Advanced Fuel Filtration System
Abstract:The objective of this proposal is to demonstrate the feasibility of an innovative design that combines a water-selective and surfactant-inert filter cartridge, with cross-flow filtration (CFF), and a high capacity spiral-wound membrane element design into an, integrated and individually contained filter cartridge. The water-selective filter allows fuel oil to pass through its membrane and repels water on the surface. CFF makes use of the shear force parallel to the filter medium to reduce the contaminant formation and water adsorption on the filter surface. The spiral-wound element design gives the maximum membrane filtration area in a given volume. The filtration unit is composed of the individually contained cartridges (modules). The module design makes the upgrade and down-grade of the system capacity very flexible. The proposed design will offer a safe, reliable, high capacity, efficient, compact, and advanced filtration system. The design is also suitable for scaling to different sizes for various applications of the Navy. It can equally well be used in various commercial fuel oil filtration systems.

Title:Fire Resistant, Labor Saving, Reduced Weight, Pipe Coupling (Flange)
Abstract:An innovative, technologically advanced piping connector will be designed, prototyped and tested to meet the existing and growing needs of the Navy for a compact cost effective coupling. The recognized limitations/disadvantages of currently available connectors will be minimized or overcome by specific design, materials, and application modifications of currently available technology. The proposed pipe coupling will have a far-reaching impact on future Naval operations and ship design. The compact coupling will allow tighter spacing of pipe headers to minimize both on-board and shore-based mechanical spaces. Its fire-resistant design will help protect Navy personnel from injury and loss of life. The mechanical properties of the connector will make it smaller, lighter and stronger than any make and break piping connection in existence today. Installation and maintenance of the coupling will be faster and easier thereby reducing cost and required craftsman training and skill.

Title:Fire Resistant, Labor Saving, Reduced Weight, Pipe Coupling (Flange)
Abstract:Conventional flange-type pipe couplings used aboard U.S. Navy surface ships and submarines typically have a large number of axially oriented bolts located around the circumference of the flange. The installation of conventional pipe couplings requires equal access to all of the bolts to ensure evenly torqued joints. The large number of bolts and accessibility difficulties with conventional pipe couplings results in a labor-intensive process for the removal and installation of these couplings. Nearby structures and equipment often have to be removed and reinstalled to gain access to the hidden bolts, or joints are inadequately tightened in cases where removal of nearby structures is not feasible. Texas Research Institute Austin, Inc. proposes to develop a low-cost, lightweight, fire-resistant, easily accessible composite pipe coupling that meets the requirements of MIL-STD-777E. The use of composite materials will reduce the cost and weight of the coupling while providing a reliable, fire-resistant, corrosion-free service life in excess of 15 years. Development of a low-cost, lightweight, easily accessible, fire-resistant composite pipe coupling has immediate Phase III applications for use aboard U.S. Navy surface ships and submarines. Commercial applications for composite pipe couplings include the offshore oil and gas, and commercial shipping industries.

Title:Low-Cost, Zero Halogen Optical Cable Jacket to Meet Mil-C-85045 and UL-910 Standards
Abstract:Foster-Miller proposes to extend our successful previous work involving intumescent fire retardant additives to develop a new class of zero halogen fiber optic cable jacket that is safer, fire-resistant and more economical. Our technical approach combines three enabling technologies to produce an innovative jacketing material that is ideal for shipboard and other cable applications. These key technologies include cross-linkable polyethylene polymers, intumescent char-forming fire retardant additives (IFRAs) and polymeric coupling agents that maintain jacket flexibility and enable high IFRA loadings. During normal service, our Intumescent Optical Cable Jacket (IOCJ) meets MIL-C-85045 performance requirements. Upon exposure to fire, the IOCJ expands into a tough, durable, insulating foamed carbonaceous/inorganic char that extinguishes burning and insulates underlying optical fibers from heat of the fire. The IOCJ meets UL 910 fire safety standards. It is self-extinguishing and non-dripping, produces no toxic, halogen-containing gases and emits low smoke, This feature protects crew members and provides time to transmit critical data before cable failure occurs. Phase I will demonstrate feasibility of meeting both MIL-C-85045 and UL-910 with the IOCJ. Our team includes an optical cable manufacturer and experts in zero halogen FRs as well as cable extrusion coating. (p00444) Our fire-resistant, zero halogen intumescent optical cabling jacket, the IOCJ, will improve the safety of U.S. Navy shipboard personnel in the event of a fire by self-extinguishing when ignited and not releasing toxic, irritating halogenated acid fumes upon burning. This technology will have strong commercial potential in safer, improved fire performance optical and electrical cable jackets and wiring insulation.

Title:Cabling Jackets with Zero Halogen to Meet UL910 Flame Test
Abstract:Material Innovation, Inc. (MII) will develop a zero halogen fire resistant material for use in plenum cable jackets, which passes the UL910 flame test. Furthermore, the jacket will be cross-linkable with consistent process-ability and persistent fire resistance at a competitive price. Non-halogen fire resistant technology is one of the most effective methods of reducing fire hazards in a confined space such as the inside of a sea vessel or an aircraft. The zero halogen material offers several advantages over halogenated material upon burning, such as reduced toxic potency of gases, reduced corrosivity of gases, and reduced smoke generation. In Phase I, MII will first develop a silicone containing cross-linkable polyolefin base resin. Then this base resin will be modified by the addition of a phosphorous containing polymer, nano-caly, or polyethersulphone to give several candidates for screening. The ideal material formulation will be chosen based on flame and thermal tests using thermogravimetric analysis and cone calorimeter in conjunction with mechanical tests for tensile strength, elongation, and flexural modulus. Antioxidants and processing aids are also screened for consistent production. In Phase II, this material will be used to produce prototype plenum cables that pass UL910 flame tests for evaluations by interested government agencies and commercial manufacturers. The development of zero halogen, fire resistant cables provides improved fire safety in confined areas where human lives are at stake, and allows people more time to escape from a fire, for example, from an aircraft, a submarine, a shipboard, a subway, or a building. The reduction in corrosive gases during a fire minimizes the damage to sensitive electronic equipment such as in a telephone switching station, or a data processing center. The use of zero halogen cables also offers benefits in lower insurance costs, a reduction in environmental pollution, and compliance with government regulations. The estimated savings is 300 million dollars annually for industrial, commercial, residential, and hotel applications in the US using this new technology.

Title:Cabling Jackets with Zero Halogen to Meet UL910 Flame Test
Abstract:The combustible nature of polymeric cable jacket materials used aboard U.S. Naval ships is a critical issue for personnel safety. This cable jacket is the material that forms a protective layer around a bundle of fibers, buffered fibers, ribbons or OFCC's. Current shipboard cable jackets are formulated with hydrated metal oxide flame retardant (FR) additives in order to meet the Navy's requirement for non-halogenated compounds. Use of metal oxide FR additives results in jacket materials that meet Naval requirements, however, these same formulations do not meet commercial plenum requirements. Texas Research Institute Austin, Inc. (TRI/Austin) proposes a new dual use cable that will allow the Navy to procure cables from a larger base of suppliers. In turn, this will foster a more competitive atmosphere for acquisitions resulting in cost savings for the Navy. Phase I work will include development of cable jacket compounds that will meet both MIL-PRF-85045F and UL-910 flammability standards. The feasibility of increasing polymer flammability resistance via a combined approach using nanocomposites and conventional non-halogenated FR additives will be determined. Commercial transition of the product will involve full-scale compounding of the jacket materials by RTP Co. and complete cable fabrication by Chromatic Technologies, Inc., during Phase II. Development of a dual use cable that meets both MIL-PRF-85045F and UL-910 will reduce costs to U.S. Navy. Many fire fatalities are due to the production of toxic fumes and thick smoke preventing escape. Development of a product that enhances flame resistance and reduces toxic smoke emissions will potentially save lives. Commercial applications will be found in aerospace, construction, and automotive sectors.

Title:Low-Cost Coherent Laser Radar Wind Sensor
Abstract:Wind estimation is a large component in the error budget for LCAC line-charge deployments. The Navy currently has no viable capability for measuring range and cross winds onboard an LCAC. Aim-point accuracy would be greatly enhanced by precise wind measurements. CTI proposes a novel, compact eyesafe laser wind sensor to meet the Navy's measurement requirements. The proposed sensor incorporates a scannerless, air-cooled transceiver technology, which meets or exceeds LCAC measurement requirements. Preliminary performance modeling suggests that a low power (less than 1 Watt) sensor will be capable of making high speed, approximately 1 Hz, range and cross wind velocity estimates with a precision of less than 10 cm/s and a maximum measurement range in excess of 1 km. System degradation, from fog, rain, sea-spay, etc., by as much as 20 dB still results in a measurement precision that meets requirements. In the proposed Phase I/II program, CTI plans to leverage ongoing activities to develop a low-cost wind sensor for clear-air-turbulence detection onboard commercial aircraft. In Phase I CTI will explore the baseline and alternate approaches to determine the most cost-effective solution using high-performance lidar modeling codes. Phase I will culminate into a prototype sensor design and production cost estimate for LCAC applications. In Phase II CTI will develop, test and demonstrate the prototype sensor based upon the Phase I design. Production costs are anticipated to be substantially less than the LCAC requirement. The proposed program will result in the preliminary design of a low-cost, compact, scannerless, air-cooled laser transceiver for short-range wind velocity measurements. This technology will have application in many military as well as commercial settings. Potential commercial applications include, general aviation wind shear detection, airport wind surveillance, environmental monitoring, and in sporting markets like sailing, riflery, etc.

The ability to compensate for the wind greatly enhances the accuaracy of the assault breaching system launched from LCAC. The proposed LIDAR wind sensor will result in greatly enhance wind accuracy in the launching of assault breaching systems and weapon firing for both small and large caliber weapons. Commercial applications include windshear detection for airline safety as well as airspeed measurement for helicopters outside of the rotor wash influence.

Title:Scanning Coherent Doppler LIDAR for Bulk Ocean Current Measurements
Abstract:A scanning coherent (heterodyne) Doppler LIDAR velocimeter suitable for non-contact measurement of sub-surface bulk ocean currents is proposed. The Doppler LIDAR velocimeter design will provide accurate current speed and direction in three dimensions from a helicopter at altitudes up to 500 feet while mitigating the effects of surface noise, partial depolarization of the return, spatial and temporal coherence degradation, and platform motions. The LIDAR will be range resolved to mitigate surface noise effects. Current direction will be determined by using a conical scan. The measured doppler velocity as a function of azimuthal scan angle will be a periodic signal whose amplitude, phase, and offset determine the 3D current direction and speed. Using GPS data, inertial measurement unit (IMU) data, and scanner encoder data, the effects of the helicopter's motion can be subtracted out of the signal. Initial design models indicate that 1 knot speed accuracy and 5 degrees direction accuracy are achievable. In Phase I, design trade studies will compare the performance of several doppler velocimeter configurations through detailed computer models and simulations. An optimized design for a Phase II breadboard prototype will be produced. The prototype development and testing will follow in Phase II. An optimized Doppler LIDAR current velocimeter will benefit mine countermeasure missions in which the current is a major factor in the mission's probability of success. This sensor will also be of great importance to missions requiring diver insertion. Such a sensor has commercial applications for commercial fishing to locate fish habitats, for civil engineering in mapping currents at proposed sites for bridges and piers, and for environmental monitoring of probable transport paths for pollutants. Arete has previously transitioned other high resolution, real time optical sensor systems to the commercial marketplace, and anticipates similar success with the scanning coherent doppler lidar system.

Title:Optical System for Remote Measurement of Ocean Currents
Abstract:We propose to develop an optical-based system to measure the velocity of ocean currents from a helicopter. Two strategies discussed in the proposal, are capable of providing depth-resolved velocity. Preliminary analyses performed in preparation of this proposal show that both strategies should be capable of measuring velocity with the required 1-knot resolution. We anticipate, however, that due to practical and cost considerations, one of the strategies will be down-selected and that the prototype system will be built around it. Analytical studies and proof-of-concept experiments are planned for the Phase I effort culminating in the conceptual design of a fieldable system. The fully developed system will be capable of measuring the velocity distribution of the ocean currents as a function of depth over large areas. Commercial applications include managing oil spills, measuring the dispersion of pollutants in the ocean, and studying fish habitat.

Title:LASER Vibration Monitoring of Unmanned Machinery
Abstract:Condition Based Maintenance has been shown to be effective in reducing costs and failures compared with Preventative Maintenance. Much shipboard equipment now has either permanently mounted transducers with connections to remote pickup or are serviced by a roving system consisting of transducers and a data logger. The Navy is also moving to systems that connect to a ship's network. But it will not be cost effective to provide a dedicated connection to many small and mid-sized units that exist in ship's compartments. The solution to this problem is a single sensor and processor servicing a number of units. It is proposed here that this be done using a laser vibrometer that sequentially gathers vibration data from a group of machines by illuminating them at particular test points. The light beam is directed to a particular test point by the combination of a vibrometer rotating table and a mirror. Issues with regard to the feasibility of the system include the vibration of the vibrometer and the mirror(s) and surface contamination of the mirror(s) and the retro-reflective tape at the test point. A simulation of a test bay allows us to determine the effects of vibration, contamination, and optical alignment. Reduced manpower requirements, compatibility with LAN shipboard information systems, improved access to some machines, remote operation, download of new software for data analysis

Title:Design and develop a real-time on-line RMA trends and analysis reporting assessment database for Towed Array Systems
Abstract:Submarine Towed Array Systems (TAS) need a process for automating the collection of system specific data related to fleet-wide operational performance. The purpose of implementing such a process is to realize the benefits of applying Condition Based Maintenance (CBM) to these remotely operated, externally located systems. This process should be an integration of elements which automatically collects real-time on-line Reliability, Maintainability and Availability (RMA) data, conducts diagnostic/prognostic analysis, and provides reports and access to users throughout the community. Analysis will include total and sub-system TAS health assessment and prediction, trending of input and output data and other selected maintenance related functions. The development of an integrated hardware and embedded software system with support hardware is required to construct a process accomplishing these functions. The LCE/ARET TEAM proposes the design and development of a COTS-based automated data collection, centralized repository, and analysis system for TAS RMA related data. This effort leverages previously demonstrated individual ship system health monitoring results. The database will be integrated with new design and existing modeling and simulation tools to predict the Fleet TAS health. The use of a complex Bayesian Belief Network (BBN) will provide the basis for the implementation of an integrated predictive tool with process diagnostic technology. The application of an integrated BBN-based predictive reliability assessment capability to commercial equipment and process plants can be highly valuable in minimizing the down-time of production facilities. This approach can immediately improve the maintenance planning process in many industries, by scheduling outages at the most economical points in the production runs, by taking advantage of just-in-time procurement of repair parts and maintenance-related materials, and by achieving the optimum utilization of plant maintenance personnel, funding and ancillary support facilities. The true value of condition based maintenance is realized only when proactive maintenance is scheduled to avert costly non-random system failures. The potential cost savings in preventing emergent repairs and operational delays is extremely significant when the consequences of failure are ruinous. This occurs when downtime is particularly costly to the operation or when the system fails often. With the current trend of fielding more sophisticated system designs with higher performance requirements, the increased complexity decreases overall reliability. The proposed CBM predictive approach is particularly beneficial to improve these processes.

Title:Innovative Signal Processing Concepts for Active Emissions
Abstract:Current submarine acoustic intercept receivers provide inadequate detection and localization performance against active target emissions and are also highly susceptible to false alarms from clutter sources such as biologics. The proposed system will overcome these limitations by utilizing data from all available sensor suites, employing advanced signal processing and classification algorithms, and applying modern localization techniques. This system will exploit "wavefront curvature processing" techniques by using a suite of multisensor correlators, operating in parallel, to determine the time differences in an active signal arriving at the various submarine sensors. The multichannel correlators include a leading-edge detector for CW signal detection and a broadband correlator for FM-type signals (e.g., hyperbolic frequency modulated). Utilizing data from hydrophones located along the length of the submarine (e.g., AN/BQA-8, CRH, and WLR-9) sensor aperture will be maximized, thus improving target localization measurements such as bearing and range. Furthermore, detection ranges will be increased by using beamformed data from the wide-aperture array and/or spherical array. The proposed system will provide the United States Navy with a unique and cost-effective method of automatically detecting, localizing, and classifying active acoustic emissions from targets of interest. This system will demonstrate the feasibility of using current submarine sensors to solve crucial active intercept receiver needs.

Title:Innovative Signal Processing Concepts for Active Emissions
Abstract:Development of innovative active emission signal processing requires the ability to exploit the full detection and localization potential of the submarine or surface ships sensor suite. Providing a defensive capability that can rapidly detect, classify and localize potential threats (eg. incoming torpedoes) requires signal-processing automation techniques that when integrated together yield a total solution. Integration of several stand-alone active intercept processors that exist today for both the submarine and surface ship platforms can provide the necessary technologies to achieve that goal. Finally, through this integration development, significant life cycle cost-savings, risk-mitigation and platform space and weight reductions are achievable. The results of this project are anticipated to have application to both commercial and military systems. Initial customers are intended to be PMS401, PMS415, PMS425, and PMS450 programs. Since the research is targeted towards system integration, detection, classification and localization techniques for active emission signals, the resulting technologies from this topic could be used support complex-theater threat assessment, war gaming, airborne surveillance, Theater Air Defense (TAD) detection, classification, and tracking systems. Finally, this research will provide with the opportunity to identify new methods for achieving high performance innovative signal processing applications using industry standard development environments.

Title:Plug-and-Play Network Administration
Abstract:We propose to develop a set of software tools to assist shipboard network administrators. Our proposed approach leverages a Jini-based Plug-and-Play equipment Control and Management architecture that Jackpine Technologies and Lockheed Martin are building in conjunction with the Virginia Class Submarine (NSSN) Exterior Communication System (ECS). In this SBIR, we will examine ways of assisting the system administrator's decision making process, and raising the level of automation and functional abstraction that the system can support. We will establish technical requirements for a software toolset to support network administration. We will identify the modifications needed to the core Plug-and-Play architecture to support the toolset and we will develop a top-level Graphical User Interface to support the administration function. The system we propose, once implemented, will demonstrate a new approach to maintaining complex distributed systems. In addition to the Plug-and-Play aspects of our design, our Jini-based architecture will provide the means and mechanisms for non-intrusive monitoring and administration of a networked system. The first target for our technology is the NSSN, and then to the 688, Ohio, and Seawolf Class boats. Requirements for similar systems exist within the surface Navy and commercial market.

Title:Smart Tools to Support Shipboard Network Administrators
Abstract:COTS initiatives within the DOD over the past decade have resulted in a proliferation of platforms beset with increasingly more diverse and complex systems. These systems have been comprised of a heterogeneous fabric of COTS products each of which requires not only day-to-day administration but also periodic maintenance. The military venue must staff this task with part-time system administrators with no formal network training. Smart administrative tools, which lessen the training required to administer these systems as well as shorten the time required to manage and maintain them, can significantly benefit overall readiness. To improve the effectiveness of administration and reduce the amount of training necessary, A single tool will be developed that provides access to the existing toolsets through a single easy-to-use web based user interface. In addition, it provides the capability for multiple-source, intelligent, diagnostic aids. Furthermore, it will be open, flexible, platform independent, and extensible. It will be based heavily on Java and JINI technologies. It also provides robust interfaces for other tools, including CORBA, SQL, and TCP/IP. This framework and user interface address the needs of complex, heterogeneous networks built largely with commercial products. As such, these tools will have immediate commercial potential. The use of Java, JINI, and CORBA facilitates rapid development, platform independence, reduced cost-of-ownership, longevity, and an attractive return on investment. Furthermore, sub-components of these tools will have commercial appeal to other tools administration vendors.

Title:Development of a Nondestructive Evaluation (NDE) Technology for Inspecting Structural Welds under Coatings
Abstract:To transmit energy through the submarine anechoic coating the SMRC/FBS team proposes to use high power ultrasonic Low Frequency Guided Waves (LFGW) in the 15 - 70 kHz frequency range. Initial modeling shows that LFGW can couple into the HY-80 hull steel from the coating, and defects can be detected by keying on guided wave mode conversions. To accomplish this two new innovative transdcuer designs are proposed (there are no off-the-shelf transducers in this range): A Langevin transdcuer, similar to the Tonpilz designs used for active sonar at lower frequencies, and a conventional design transdcuer that uses an innovative piezo-composite driver. In Phase I these will be made with a center frequency of 70 kHz with skirts to 40 kHz in order to stay within the range of off-the-shelf tone-burst pulser/receiver systems, and to collect data for optimizing Phase II LFGW transdcuer designs. Testing in Phase I will center on estimating the amount of energy coupled into the hull steel and returned for detection analysis, and determining the sensitivity to weld defect detection. Marketing in Phase I includes a detailed Fleet introduction plan, presentation of results at a Navy conference, and an R&D announcement mail-out to potential industrial customers. Phase II planning includes developing a LFGW tone-burst system and LFGW trasnducers, all capable of operating at frequencies in the 15 - 70 kHz range. Inspection of welds under thick anechoic and thermal insulation coatings could save millions in insepction costs in both military and commercial markets, and improve safety margins for high dollar items such as submarines and pressure vessels. As ultrasoniuc frequencies are pushed into the low frequency regime related technology benefits can also accure for long distance guided wave NDE of heavy wall pipe and ship/submarine propulsion shaft inspections.

Title:SQUID Magnetometer for Nondestructive Evaluation (NDE) and Inspection of Ferromagnetic Structural Welds under Thick Coatings
Abstract:Lifetime monitoring of structural integrity in ships and submarines requires NDE inspection techniques capable of examination of hull welds beneath advanced coatings. The significant thickness (up to 2") and energy dissipating properties of these coatings tend to substantially degrade the capability of many conventional NDE techniques. This work proposes the development of an NDE system utilizing SQUID technology incorporating ac and dc magnetic field techniques. This would allows the capability to conduct inspections completely from the outboard side of the hull with the requisite sensitivities (noise number) and very low frequency bandwidths required for inspecting through thick coatings. We will address the following objectives: - Determine the metrics that affects the detectability of flaws in thick steel welded plates. - Examine flaw detection sensitivity to critical system variables. - Determine the optimum measurement technique for SQUID detection of flaws. - Establish the optimum SQUID magnetometer hardware configuration for detecting flaws. - Evaluate image processing and data analysis techniques. - Determine the minimum detectable flaw using existing SQUID NDE techniques. During the Phase I effort, we will adapt existing SQUID NDE equipment to measure a variety of samples to evaluate SQUID NDE as an improved Navy inspection method. The development of a laboratory instrument will provide data on hull flaws that will reduce the probability of failure of a structurally significant element. This benefits inspection planning and maintenance, reduces costs, and increases ship availability. The technologies developed will have substantial dual-use impact, both in military and civilian use. Specific benefits to the Navy shall be improved detection of planar and volumetric flaws in full-penetration butt welds covered by thick protective coatings. We anticipate substantial time and cost savings due to the ability to make inspections without the need to remove hull coatings. The ability to detect bad welds will be increased by the proposed work. Since the problem is measurement through thick coatings, the measurement methodologies developed will be also be applicable to NDE inspection during original hull construction for all Naval vessels with commensurate time and dollar reductions. There will also be benefits to the commercial sector. There are a number of applications where significant depth information is needed, but the structures may not have coatings. There is a demand for the ability to see deep flaws in ferrous structure such as commercial ships, nuclear reactor confinement vessels, oil storage tanks and rails for high speed trains. In reality, the constraints for these measurements are reduced due to the absence of thick overcoatings and reduced standoff distances. This makes it easier to design and manufacture a commercially oriented SQUID NDE inspection system. An improved NDE inspection method that can reduce the probability of structure failures has significant benefit to many industries.

Title:Application of Virtual Large Display Video Goggles to Submarine Imaging Systems
Abstract:Sonalysts, Inc. proposes leveraging our Team's extensive research and development background with state-of-the-art visual technologies to introduce goggles displaying a large field of view video scene from the periscope imaging sensors. A number of benefits are offered to the imaging system operator and his supervisor, including filling the operator's field of view and reducing peripheral distractions, thereby creating a sense of "immersion" into the current scene; and enabling the supervisor to be mobile while viewing what the operator sees. Key Phase I objectives include: defining the operational and technical requirements that will be used to assess available technology and evaluate candidate goggles, demonstrating the video scene with prototype goggles, and developing the architecture for integration of goggles with the submarine imaging system hardware and software. Our focus will ensure that submarine fleet requirements and issues are addressed and weighed in the investigation of the most appropriate commercial off-the- shelf (COTS) components. We will ensure interoperability between all components and explore the commercial applications to broaden the opportunities of this topic area. Our proposed approach will advance the state-of-the-art applications for the submarine fleet and bring increased performance opportunities for the imaging operator and his supervisor. An immersive environment that allows mobility and flexibility will be the effect of the integration of COTS goggle technology. Commercial opportunities for goggles include remote surveillance and security monitoring uses, medical and surgical procedures, and machinery diagnostics and inspections.

Title:A Highly Directional, Printed Compact Antenna for Multifunctional Submarine Communications
Abstract:An innovative, highly directional, wide-band UHF (250MHz-4000MHz) antenna for submarine applications is proposed. The proposed antenna is conformal and compact, and can be configured as an array to satisfy larger power and variable beamwidth requirements for low interference applications. It is based on a proven concept developed for wide-band sensing and communications purposes as part of a University research project. The design has already been demonstrated for UHF to 5GHz continuous band performance. Under this proposal, we intend to (a) design an array configuration to satisfy the highly directional, power, gain and mounting requirements for the proposed application, (b) account for radome and platform effects, (c) consider a smaller design of the conformal antenna element for greater flexibility. The proposed concept allows for extremely flexible designs and versions of the antenna elements have already been used for airborne conformal applications down to HF frequencies. Compact and affordable broadband conformal antennas are needed for a variety of communications applications. The proposed antenna structure(s) will have widespread uses in mobile communications including automobiles, civil and general aviation, GPS, PCS, Cellular, LAN, etc. that require multi-functionality and broad bandwidths using a single aperture.

Title:Design and Demonstration of a Compact UHF Antenna using Coaxial Beam-Rotating Antenna Technology
Abstract:This proposal presents an innovative design concept for a prototype UHF antenna that is compact in physical size, and produces a directional, circularly polarized beam steerable through 360-degrees in the horizontal plane. The proposed antenna will utilize a lensed Coaxial Beam-Rotating antenna (COBRA) feed horn and a rotatable flat plate reflector to direct a collimated, high-gain beam with circular polarization in the desired direction. The antenna will be designed to fit within a right circular cylinder 18 inches in diameter and 35 inches high. The design for this compact UHF antenna utilizes a technology developed and validated by Voss Scientific, specifically, the Coaxial Beam-Rotating Antenna. The concept uses a COBRA lens design, proprietary to Voss Scientific, to adjust the "electrical" path length of the wavefront and produce a boresight peak pattern with circular polarization. Most recently this antenna technology was utilized by the Air Force Research Laboratory for applications in its Directed Energy / High Power Microwave program. The unique properties of the COBRA have been incorporated into the proposed antenna concept, and the resulting design is expected to meet and exceed the requirements for a highly directional compact UHF antenna operating in the 800 MHz to 2500 MHz range. The proposed antenna design will meet a current military need for a compact, high gain UHF antenna with a low probability of intercept. Physical and operational properties of the proposed antenna (compact, high gain, low side lobes, circular polarization) that make it well suited to the military application, will mean that it also has potential application in the cellular phone, and Personal Communications Services industries.

Title:Non-Metallic Bearings (PDC Bearings)
Abstract:The Navy currently uses bearings that are required to operate in a variety of environments simultaneously including: dry; in a submerged marine environment; under significant physical loads; at great depths; and under ambient temperatures ranging from 30 to 125F. These bearings are used in many different types of rotating machinery, many with large diameter shafts and great loads (2 to 3 tons per shaft). Bearings used in these applications have several drawbacks. The bearings require lubrication and have been known to crack under load, which must be maintained even at great depths. Inspecting and re-lubricating these bearings is very expensive. A bearing that will meet the requirements of no lubrication, low friction, and high strength while maintaining low cost and the ability to operate in all environments mentioned above would improve the existing implementations and allow for expanded application. A Polycrystalline Diamond Compact (PDC) bearing will meet these requirements. PDC bearings have proven to be cost effective in the oil field industry. A Phase I program is designed to demonstrate the feasibility of applying PDC Bearing technology to Navy bearing needs. The program will result in a bearing design that can be retrofitted to a Navy bearing application. (p00479) Developing PDC bearings for the Navy use will increase the reliability the systems that are presently compromised by high maintenance requirements brought about by inaccessibility or sever environmental conditions. Presently PDC bearings have use in the oil field industry. The application can be leveraged into other industries where high loads, inaccessibility and environmental conditions combine for form prohibitive maintenance requirements.

Title:Low Cost Net-Formed Refractory Composites for Hot Gas Valve Components
Abstract:Hot gas valve components which can withstand rocket propellant gas environments of over 3500F are enabling for Divert and Altitude Control Systems (DACS) for endo- and exo-atmospheric inceptors. State-of-the-art hot gas valve components have limited performance and are costly to produce. In a team effort of MER and Aerojet, composite processing which can produce carbon-carbon (C/C) at under ten dollars per pound will be utilized to functional grade refractory compound compositions to produce the pure refractory compound on the composite surface. Several refractory compound composition composites will be produced and screen characterized. Select compositions will be further investigated to enhance performance as well as reduce processing cost and cycle time to 24-48 hours. Down-selected composition(s) will be fabricated into components and rocket motor tested during the option period. The optimized refractory compound composites will be translated to a missile vendor base for Navy and all DoD DACS applications as well as applications in aerospace, engines and other commercial high temperature applications.

Title:Low-Cost, Net Shape Fabrication of Propulsion and Hot Gas Components
Abstract:Techniques are needed to reduce the cost and fabrication time of refractory metal and ceramic propulsion and hot gas components. Refractory metal and ceramic materials are being used for their high operating temperatures and chemical stability. However, the difficulty of forming these materials into complex shapes has limited their application in the past. PPI proposes to demonstrate and commercialize low cost, net shape fabrication of refractory and ceramic propulsion and hot gas components using Low Pressure Plasma Spray (LPPS). The technique involves spraying material onto a mandrel of the desired shape and subsequently removing the mandrel. A primary advantage of LPPS forming over other powder metallurgy techniques is that near-net-shape spray forming of components significantly simplifies and reduces the cost of fabrication due to the high material utilization and reduction of laborious machining. Exploitation of these rapid processing techniques will decrease the cost of fabricating components by >50% and the manufacturing time by >90%. In Phase I, LPPS Parameters and forming techniques will be developed to allow the deposition of dense, stress-free materials. The techniques will then be used to fabricate and hot-fire test propulsion and hot gas components for Thiokol Propulsion and Space America, Inc. The results of the Phase I effort will clearly demonstrate the ability to fabricate low cost, stress-free refractory metal and ceramic propulsion and hot gas components. LPPS parameters, which are largely unknown for >2000C operational materials, will be developed to allow production of hot-fire test specimens. Hot-fire testing will demonstrate the ability of LPPS components to meet the stringent thermal and mechanical requirements. Clients who are supporting PPI on this technology are rocket engine and missile producers and users such as NASA, DOD, Rocketdyne, Thiokol, Aerojet, Pratt & Whitney, and Space America, Inc. In addition, PPI will develop and transfer the technology for other commercial applications such as: arc-jet thrusters, heat exchangers, heat pipes, welding electrodes, plasma facing components for nuclear reactors, gas turbines, automobile engines, incinerators, thermal control coatings, oxidation protective coatings, liners for composite parts and structures, structural jackets on tubular combustors and nozzles, and storage vessels.

Title:Powder Injection Molded Rhenium Fluidic Valves
Abstract:Kinetic kill vehicles rely on using hot gas divert systems to provide vehicle control enabling target intercept. With high Mach hit to kill vehicles, divert systems capable of upwards of 50g capabilities are used, requiring using high pressure, high-energy (temperature) hot gas divert systems. These structures must be manufactured from refractory materials, which are currently very costly and difficult to manufacture. The proposed Phase I program will demonstrate Powder Injection Molding (PIM) a liquid-activated sinterable rhenium powder and demonstrate sinterability into net-shape components. Net-shape fabrication of three valve components, including a fluidic amplifier structure, diverter ball structure with in-situ diverter ball, and 3-D supply tubing component. The resultant PIM fabrication process will result in a 90% reduction in the fabrication cost of these critical, high cost components. Innovative powder coating and low temperature sintering technology will be used to produce and characterize refractory metal composite structures for use in divert propulsion systems. The technology developed in the proposed program will result in an up to 90% reduction in the cost of LEAP solid diverter valves which are used in the NMD missile defense system, and will enable expanded applications into guided ordinance systems such as the ERGM, mortar rounds, and other defense applications.

Title:Propulsion Improvement for Long Range Guns
Abstract:This research will produce a means of increasing the muzzle velocity of Naval guns that has the lowest risk of any concepts currently known to the research community. In addition the concept will produce very nearly the greatest muzzle energy possible from a given propellant volume. This is all possible because of the integration of two, newly developed propulsion technologies along with new ideas for ignition control and travelling charges for very high velocity projectile launch requirements. Thanks to these multiple, embedded ignition sources within the propellant, the energy release can begin very gradually allowing nearly solid loading densities, assuring the maximum possible energy release from a bulk loaded charge. APTI believes that a very high burn rate (VHBR) propellant or regenerative liquid propellant based in-bore gas generator or "fumer" can provide a very practical, low risk alternative to the yet undemonstrated traveling charge. By supplying make-up gas at the base of the projectile, the projectile base pressure could be tailored for best performance. Ignition of this charge would be delayed until after peak pressure and gas generation rate controlled by means to be discussed. The delay would continue until the projectile had reached a speed that was signifigant relative to the sound speed of the combustion products. Commercial applications share many of the same potential benifits of smart charge technology but with perhaps a greater emphasis on safety. There are three safety features of smart distributed ignition that are currently not possible otherwise: 1)encoded firing signals to prevent unauthorized firing, 2)shunting of active electrical elements while not in use prevents accidental firing from E-M inputs, and 3) electrical mode shaping to produce duding upon request. Elaborate timing and selection sequences are possible for applications such as people-smart airbags that inflate to different levels according to passenger weight or different velocities according to impact speed. Fireworks displays could perhaps be made safer and much more elaborate if coded, more carefully timed igniters were used. Explosive charges made in large monolithic blocks with embedded igniters would be safer to transport and handle than bulk explosives and powdered propellants because of features like structural integrity, reduced exposed surface area, and protective covering.

Title:Propulsion Improvement for Long Range Guns
Abstract:The objective of this Phase I effort is to establish the feasibility and performance benefits of incorporating a traveling charge to achieve maximum gun launch energy while minimizing peak pressure and acceleration loads. The effort involves three primary tasks: (1) Preliminary design and analysis of single ram and double ram projectile, traveling charge, and fixed charge designs; (2) Selection of applicable traveling charge propellant compositions and corresponding grain designs; and (3) Characterize interior ballistic performance of single ram and double ram traveling charge configurations for variations of traveling charge to fixed charge mass ratios and for various delay times between ignition of the fixed charge and ignition of the traveling charge. Should the effort result in developing a traveling charge approach that can be applied to existing and/or future Navy gun systems, significant range performance increases could potentially be realized without imposing additional structural demands on either the gun system or the projectile.

Title:A Smart Cartridge for Long Range Gun Propulsion Improvements
Abstract:The Navy's long-range gun fire support was greatly diminished when 16-inch guns were retired from the fleet, leaving the 5-inch 54 gun as the highest performance naval gun. The emergence of antiship cruise missiles among potentially adversarial states has created the need for greater standoff and even greater range for Navy guns. This need is real and immediate. We believe that the bests approach for extending the range of Navy 5-inch guns is through the use of efficient high-energy propelling charges. The proposedl concept features a dense propelling charge with roughly 40 percent increase in charge energy over that of a conventional loose granular propellant bed while still using a 5-inch cartridge case. To achieve an efficient interior ballistic process, the ignition process will feature two or more electronically controlled steps that will allow great latitude in selection of charge design parameters. Concept feasibility will be determined during the proposed Phase I program using the XKTC and NGEN interior ballistics codes, which are recognized throughout the gun community as being state-of-the-art in interior ballistics simulation. The smart cartridge concept has many benefits including no projectile parasitic weight, use of the current 5-inch cartridge case if required, ability to compensate for ambient temperature effects, and ability to use a common charge for several projectiles by changing controller setpoint parameters.

Title:ADVANCED REACTIVE MATERIALS AS PROPELLANTS
Abstract:A family of energetic propellants and solid fuels will be developed in the proposed Phase I study. Arrangement of energetic material supply such as ultra-fine aluminum and boron carbide powders has been made through a vendor with special technology for energetic powders development. The selection of energetic propellant formulations is based upon the propulsion performance and safety behavior of these energetic materials. The characterization of the combustion and safety behavior will be conducted by the state-of-the-art techniques. The strand burning rates, temperature sensitivities, burning stability parameters, and activation energies will be characterized using well-equipped diagnostic instruments and facility. Commercialization of these propellants and energetic solid fuels has been planned for many applications, as described in the following section. Collaboration with numerous industrial companies has also been planned for broad commercial application of these new generation of energetic materials. There are numerous benefits from this proposed research. First, the effectiveness of ultra-fine energetic powders on the control of propellant and solid fuel burning behavior will be demonstrated from this research. Second, the feasibility of utilizing energetic materials for propulsion purposes will be assessed. Third, once the superior performance of a family of high energy reactive materials has been demonstrated, many industrial companies will benefit from the use of these materials for both military and commercial applications. The proposer has broad contacts with various companies involved in propellant manufacturing, space propulsion, safety device design and fabrication, test and evaluation, and development of special tools. These companies include: Thiokol Aerospace and Industrial Technologies, Alliant TechSystem, Inc., United Technology - Chemical System Division, Aerojet Propulsion, Aerospace Corporation, Primex Aerospace Company, Atlantic Research Corporation, Talley Defense Systems, Lockheed Martin, Boeing Aerospace, North American Rocketdyne, Air Products and Chemical,Inc., and many others. As previously stated, many of these companies will be interested in using high-performance propellants for various commercial applications. Some of these applications are listed below: - airbag inflators for automobiles, - emergency escape systems for aircrafts - connecting large diameter electric cables by actuating a compression unit energized by rapid combustion process of energetic materials - high-pressure water jet for cutting explosives, cheeses, steel pipes, etc. - demolition of unwanted structures such as buildings, bridges, towers, etc. - high-performance space propulsion rockets for space exploration - planned avalanches triggered by using explosives, - rock and earth blasting for mining purposes by setting off explosives - improvements of firework displays - carving and etching into solid surfaces using high-energy reactive materials

Title:ADVANCED REACTIVE MATERIALS AS PROPELLANTS
Abstract:In order to gain the full potential from application of metal and elemental powder based materials to generate an enhanced propellant formulation, General Sciences,Incorporated (GSI), proposes to investigate the use of intrinsically reactive intermetallic based compositions for the production of an increase impulse propellant. The Phase I program will establish a basis for the application and selection of reactive intermetallic systems, to include an analysis of the reaction/combustion process in a typical propellant composition, determination(experimentally) of the change in the resultant propellant characteristics (e.g., thrust, burn rate,specific impulse) and an initial material safety screening evaluation. The successful completion of this effort will result in an innovative technique to increase the performance of not only cast propellants, but also of gun propellants, ducted propellant engines and hybrid motors. Successful completion of the proposed effort will result in the identification of propellant formulations producing a higher specific impulse. This technology is capable of being utilized by the majority of propellant application in both the military and commercial sector including rocket propulsion, ducted ram jets and gas generators. A direct transition of the technology developed can be made to the SCRAMSHELL effort under the Hypersonic Gun Launched Weapons Technology Program. Initial discussions for transition of this technology have been started and potential bridge and/or follow-on funding identified.

Title:MMC Winged Extended Range Advanced Projectile
Abstract:Triton Systems, Inc. (TSI) proposes to develop a hybrid continuous fiber aluminum matrix composite (AMC) polymer matrix composite (PMC) material to join an AMC folding wing to the casing of a gun launched modified ERGM round to attain extended range. TSI has teamed with Custom Analytical Engineering Systems (CAES) who will provide design and systems level expertise for this effort. A ceramic fiber reinforced metal matrix composite wing is proposed that will fold around the projectile casing inside a sabot and deploy when the sabot is discarded after firing. The stiff, thin, metal matrix composite will provide an increased lift to drag ratio to the munition and will leave most of the rocket motor bay available for the an increase in warhead size. A slight decrease in the outside diameter of the projectile will be necessary to allow for the sabot and the wings within the 5-in- bore of the barrel. The hybrid composite will also enable the PMC munitions casing to be more efficiently joined to the end fittings. It is anticipated that the hybrid joint will permit the compressive load on the munitions casing to be significantly increased, allowing for more setback G's and a higher muzzle velocity. The hybrid PMC MMC joint proposed for development under this program has an extensive array of potential commercial applications. Joining PMC's to standard fittings for assembly is the classic problem associated with utilizing PMC materials. This program proposes to develop the solution to integrate near net shape cast MMC materials to PMC's in load bearing structures. A few applications include missile casing end fittings, space truss tube end fittings, bicycle frame fittings, automobile frames, bodies and joints, drive shaft end fittings, propeller hub assemblies and airframe components of all kinds.

Title:Extended-Range Projectile Using Body-Conformal Oblique Wing/Tails with Smart Structure Control
Abstract:ZONA proposes an innovative EGRM projectile design using body-conformal oblique wing/tails with smart-structure (actuator) control. This guided projectile can maintain optimal lift-to-drag ratio throughout its supersonic to subsonic flight phases and can achieve without rocket motor an extended range exceeding the maximum range required (63nm). With the guidance/nose cone section unaltered, the wing/tails fit conformally to the ERGM projectile skin structure with minimum impact to the remaining internal volume. The improved performance include: (a) large increase in the volume and warhead payload, (b) extended range; (c) increased mission flexibility by enhanced maneuverability; (d) reduced flight time; and (e) cost reduction. The proposed approach is to merge the outstanding aerodynamic characteristics of the oblique-wing/tails with smart structures for twist/camber control to achieve optimal lift-to-drag ratios throughout flight and enhanced maneuverability by adding direct lift control. Central in the smart-structure control system design is the use of ASTROS*(Automated Structural Optimization Systems, developed and improved by AFRL/ZONA) with other control algorithms. Other proposed tasks include smart-structure control system design, wing/tail smart-structures design integration, performance evaluation using a 6-DOF comprehensive simulation and to ingrate the simulation into the Phoenix Integration Corporation Model Center product. ZONA will package the developed software with NASTRAN and ASTROS* and jointly market them with MSC as commercialized software products to ZONA and MSC's customers worldwide. If successful, the complete hardware/software smart-structure control technology should be adopted by the aerospace/defense industry to design the next generation missile and air vehicles. Potential customers include: DoD, NASA, private sectors for NSFS projectiles, missiles, drones and UAV/UCAV and TAV's. Technology/commercial transition can be carried over to the Navy/ALAM program, the US Army/Marine 115mm artillery program, and its anti-ship missions.

Title: Effect of Ocean Waves on Tracking Low-E Objects in Multipath
Abstract:To develop and evaluate the next generation of Low-E (low elevation) detection and tracking algorithms, the Navy surface radar community must have more accurate, efficient and robust models of the effects of ocean waves and multipath on radar signal propagation. This must include a realistic, oceanographic-based, facet-model of the sea surface. Existing approaches have utilized a flat surface with a single signal reflection point coupled with a 'roughness' factor to account for sea-state. An alternative technique, suggested in the technical information package accompanying this topic, used a simplified facet-model to allow the use of ray-optics. The proposed TSC approach, utilizing a realistic, upgradable, oceangraphic-based sea-facet model together with a full-wave propagation technique under the Parabolic-Equation approximation, is more general, and provides higher fidelity. It will enable the model to simulate Low-E monopulse measurements in the presence of interference and diffraction under standard or anomalous propagation. Coupled with existing TSC techniques to model propagation and sea clutter in real-time, this will provide the Navy with a comprehensive tool, supportive of both shipboard radar detection and measurement modeling capabilities against Low-E targets in the presence of ocean wave propagation, and clutter effect. This research and development effort could lead to a unified automated tool capable of providing real time, high fidelity, modeling of radar propagation, monopulse measurement and sea clutter, in the presence of ocean waves, multipath, diffraction, and anomalous propagation. This would benefit every Navy simulation concerned with (a) Low-E search, track, or engagement radar desigh; (b)Low-E tracking algorithm development; or (c) Low-E tracking and tracking algorithm assessment

Title:Force Level Automated Certification of Downward Compatible Baseline Software
Abstract:Regression testing is a significant problem in software development, particularly during the maintenance phase. It involves repeated execution of previous test cases to instill confidence in modified software. Even after minor changes, most commercial vendors and military software engineering directorates perform regression testing. Sessions may run overnight or longer, especially when human intervention is necessary for oversight. Trident proposes to develop a re-certification methodology, called modular regression testing, and an automated certification capability to reduce required regression testing efforts. The foundation of this methodology is the local certifiability and modular reasoning arguments submitted by the software reuse research community. Three main concepts constitute the heart of the methodology. Design for testability that is based on local certifiability principles increases the effectiveness of the methodology. The firewall computation algorithm distinguishes modified and unmodified components automatically given incremental modifications. The test reselection algorithm extracts a subset of test cases associated with the candidate-unmodified components. The test execution s upport environment will use customizable test drivers that automatically run the test cases against unmodified components. Applicability of the methodology to COTS domains in the context of Navy's Cooperative Engagement Capability will also be investigated. Dramatical reduction of regression testing efforts on existing systems will be an immediate benefit of the methodology. Introduction of design for testability guidelines will allow designers and developers of software systems to engineer testability directly into the software, thereby avoiding costly testing and re-testing problems. The guidelines will suggest principles and design attributes (metrics) that support modular reasoning and local certifiability. The relationships between well-known complexity metrics and testability will also be reported. Modular r regression methodology and the certification capability could lead to substantial reduction in maintenance costs, improvement in software reuse, and increase in quality of software. Development of an open and extensible program analysis and test execution support environment including metrics collectors and automated test suite generators is our long-term goal.

Title:
Abstract:The innovation of this SBIR Phase I project is the development of an automated test and re-certification capability based on "MMP Fusion" technology. MMP Fusion is a hybrid approach that combines modification-based test selection, test set minimization, test set prioritization technology. Capture-playback technology is used to record (capture) test procedures and results from previous versions of the software system and then re-execute (playback) these test procedures for regression testing and re-certification of the new version of the software system. Test selection, test set minimization and test set prioritization will be primarily accomplished using a list of software system changes and information (based on results from test cases run on previous versions) about what area within the software system each test case covers. An automated MMP Most systems still require heavy instrumentation at the code level to assess the level of software code coverage (block coverage, p-use coverage, branch coverage, etc.) produced by a test suite. In this SBIR project we aim to relax the need for heavy instrumentation of software system, integrate appropriate capture-playback technology and to create a prototype regression test and re-certification technology that would be appropriate for mission critical force level system of systems. Anticipated Benefits: Fusion based test and re-certification capability will provide significant cost savings (in time, money and effort) over manual methods during regression testing and re-certification of the multiple legacy computing systems (such as combat systems, aerospace, telecommunications, etc.) that receive the new downward compatible baseline software system enhancements. DOD projects that would benefit are: Cooperative Engagement Capability (CEC), Combat Systems, Common Command & Decision (CC&D), Next Generation Internet, GCCS-LES and ADCON-21. Ship classes and systems for which automated MMP Fusion Technology may be relevant include Aegis future baselines, SC-21, Arsenal Ship, CVX, LHX, LPD-17 (Flight II), New Attack Submarine (NSSN), Coordination Systems and Force Level System of Systems.

Title:Reconfigurable Maintenance and Diagnostic Equipment
Abstract:Typical shipboard electronic systems contain many unique or special purpose components, boards, and assemblies. In the past, it has been necessary to carry equally specialized spares or Maintenance Assist Modules (MAM). Tanner Research believes that its Reconfigurable Computer technology offers a cost-effective approach to the emulation of multiple board-types with standard, reconfigurable hardware, and that the technology will permit significant reductions in the shipboard inventory of spares. The Tanner Research Reconfigurable Computer can be configured to simulate existing boards and to implement diagnostic and maintenance equipment. The Tanner Research technology employs high-density Field-Programmable Gate Arrays (FPGAs), memories, interface circuits, and re-usable circuit designs in a modular hardware architecture. Re-usable circuit designs include general purpose elements such as microprocessor cores as well as elements that emulate specialized military circuits. Low-cost equipment-specific and mission-specific adapter boards are used to incorporate reconfigurable hardware modules into existing shipboard electronic systems. The Tanner Research technology is highly flexible, and it will readily adapt to changing system requirements in the future, even as it permits the development of solutions that are tailored to specific system requirements today. The potential of the Tanner Research Reconfigurable Computer extends well beyond the needs of Reconfigurable Maintenance and Diagnostic Assemblies (RMDA). It offers a low-cost approach to the replacement of legacy hardware, a high-performance approach to dedicated signal- and data-processing hardware, and a cost-effective approach to reduced design cycle times and extended product lifetimes.

Title:High Velocity Combustion Processes in the Solid State
Abstract:The goal of this proposal is to analyze processes which can substantially contribute toward understanding phenomena relevant to ultra-high rate of energy release. Three major topics will be analyzed: I) SHS fast deflagration and detonation, II) metal loaded explosives, and III) ultra-fast combustion in the system aluminum-oxidizer in solid missile fuel. Following important topics will be discussed: reactivity and shear stress, stored energy, reaction and role of diffusion, SHS deflagration and detonation, shear induced detonation, effect of ultra-fine metallic particles and design of insensitive warheads. Classical explosives in bombs, warheads and torpedoes, which are used by the Department of Defense, can be replaced by more powerful and inexpensive SHS reactions. Consequently the lethality of bombs, warheads and torpedoes can be substantially improved. If properly arranged SHS explosives feature very low thermal and impact sensitivity. In the civilian sector major application of the proposed SHS explosives is development of explosives, featuring low level of sonic effects. These explosives can be used in blasting rocks and demolishing concrete structures in highly populated urban areas.

Title:Upward Compatible Baseline Support Framework For Effective Force Level System Regression Testing and Certification
Abstract:An emerging direction in software development is the engineering of large complex system of systems from plug-compatible and pre-certified software components that are interoperable and compatible with the baseline coordination protocols. However, such systems continuously evolve as COTS components are substituted or baselines are upgraded. Continuous change and lack of modular behavioral contracts with associated localized certification capabilities that detect semantic mismatches make retesting time consuming and manpower intensive. We will report the current state of the commercial practice and research initiatives in dependable software upgradability. Our proposal builds on the lessons learned from these initiatives and constitutes an adaptable certification framework to detect behavioral mismatches both at the architecture and system implementation level. The expected contributions are explicit capture of the component dependencies using behavioral component relationships, direct applicability to COTS systems, and tractable reasoning and testing for interoperability based on modular representation and certification of interaction and coordination policies, with particular attention paid to understanding critical issues necessary for applicability to Cooperative Engagement Capability. The framework will be adaptable to a variety of functional and non-functional (e.g., security, fault-tolerance) aspects of a system. Military software engineering directorates and commercial vendors do regression testing even after minor changes. It is not unusual for each regression testing session to run overnight or even longer. Unless modular certification based on principle of local certifiability is followed, existing approaches are doomed to fail as the size and complexity of software systems continue to increase. Successful completion of this project will be a significant advancement in the state-of-the-art in V&V for automated interoperability and upward compatibility checking without exhaustive testing. The methodology and the certification capability could lead to substantial reduction in maintenance costs, improvement in software reuse, and increase in quality of software.

Title:Multi-Static Active Sonar Processing with Unknown Transmission Type and/or Unknown Source Location
Abstract:The increased need for active echo detection is driven by the continually evolving quieter threat submarines and noisier acoustic environments that severely limit passive sonar detection performance. Submarines often operate in areas where natural or man-made acoustic energy sources of unknown or non-cooperative origin are present. The emphasis in this Phase I SBIR project will be defining signal and data processing algorithms that provide useful bi-static detection and localization performance using sources of opportunity. Successful completion of these studies will provide acoustic parameter values needed to estimate own ship vulnerability to potential hostile sonar-platform locations that may also use these emissions to echo range and make use of the bi-static echo parameter measurements to formulate a strategy for maintaining the required degree of stealth while increasing the effective area for threat detection. Signal and data processing algorithms and tradeoff studies are proposed for: 1) Precise characterization of active emissions, 2) Near optimum Bi-Static echo detection, and 3) Accurate target Localization. It is anticipated that successful completion of the Phase I and II work will result in technology that merits inclusion in the existing sonar processing suite through the Advanced Processor Build (APB) program. DSR believes that opportunistic acoustic source exploitation, implemented in portable software for execution on low-cost commercial hardware, will result in major capability improvement in the sonar system. The immediate objective will be to obtain a Phase III SBIR contract to adapt the Phase II system to meet the specific system requirements.

Title:Innovative Broadband Signal Processing Algorithms
Abstract:The proposed Phase I SBIR study for active broadband sonar signal processing defines an integrated analysis approach and several innovative algorithms which will produce an effective sonar system design. The need for improved broadband active sonar is driven by emphasis on submarine detection in shallow water and the reduced radiated noise of threat submarines, which together reduce the effectiveness of passive detection. The detection of slow moving submarines is more often limited by reverberation and multipath propagation in littoral waters. Increasing signal bandwidth processed has the potential to improve processing gain against reverberation, increase range resolution and help discern complex multipath structures. The program develops active sonar signal processing technology that assists in the detection, classification and localization of target submarines. In addition, candidate algorithms will be evaluated for feasibility of implementation on existing Navy processors and arrays. Signal processing algorithms and design tradeoff studies are proposed for (1) Transmit waveform design; (2) Spatial processing; (3) Frequency diversity and sub-band processing; (4) Classification and tracking; and (5) Multi-static operation. It is anticipated that successful completion of the Phase I and II work will result in technology that merits inclusion in the existing sonar processing suite through the Advanced Processor Build (APB) program. DSR believes that the exploitation of wide-bandwidth active sonar, implemented in portable software for execution on low-cost commercial hardware, will result in major capability improvement in the sonar system. This added capability will be a significant improvement to an existing product line. The immediate objective will be to obtain a Phase III SBIR contract to adapt the Phase II system to meet the specific system requirements.

Title:Advanced Automated Sonar Operator Machine Interface
Abstract:Sonar processing traditionally has provided the watchstander with a two dimensional display in which the user must make many decisions as to the variable parameters of the presentation. The proposed research addresses the need to ease the workload upon the watchstander and provide a more easily discernable subsurface view through the use of three dimensional presentations. CHI Systems intends to utilize the iGENtm product as the main feature of an intelligent display agent which is central to the research. The detection, classification and localization information will be presented to a watchstander in such a manner that personnel numbers can be reduced through artificial intelligence methodologies. The Phase I research is accomplished in five tasks and will result in a prototype of the Display Agent for Detection Augmentation (DADA). The DADA software architecture can be generalized and used for military and commercial (in aircraft and ships) radar systems both in operational scenarios and training. Additional commercialization uses include air traffic control to reduce the probability of accident.

Title:Multistatic Acoustic Source for Unmanned Underwater Vehicles (UUV)
Abstract:A low frequency underwater acoustic source for Unmanned Underwater Vehicles (UUV) will be developed. The transducer will operate in the 300 Hz to 500 Hz spectrum with an acoustic source level of at least 205 dB /1uPa @ 1m. The proposed innovative transducer design will be based on the X-spring design (U. S. Patent 4,845,688 "Electromechanical Transduction Apparatus,"). The new X-spring transducer element configuration proposed uses a large 33 mode ring which drives two concave cone shaped shells which, in turn, amplify the motion translated to two symmetrical pistons. The design allows an increase in radiating area and a magnified motion resulting in a larger volume velocity than could be achieved from a ring alone. Also, the radiation load is magnified yielding a low Q and high mechanical efficiency even at low frequencies. Although a single transducer should be capable of achieving the desired acoustic source level, we present a directional capability scheme where an improved directivity index can be achieved reducing the power needed for the desired level. A UUV transducer for multi-static sonar applications will be developed. The ring driven X-spring approach should provide a scalable approach applicable to current and future underwater acoustic systems. The technology should provide improvement for low frequency sonar systems, and for oceanographic and possibly tomography applications.

Title:Topologically and Geographically Accurate DTED Compression
Abstract:The DoD collects an ever-increasing amount of digital terrain elevation data (DTED) that is an indispensable source of information for applications that use geo-spatial information. We propose here a new, revolutionary technology that is perfectly suited for compressing DTED. Existing compression technology is not appropriate for the special features of DTED. These methods, when applied to DTED, lose derivative information. The new compression method proposed here has advantages over standard technologies as follows: a) It can gracefully handle topological changes such as breaking or merging which occur, for example, as the scale is changed or if the curve or surface is deformed. b) Geometric quantities on the compressed data can be easily and accurately evaluated. c) It has a simple multiresolution representation. The techniques involved include Total Variation (TV) restoration, Essentially Non-Oscillatory (ENO) interpolation, and the level set method. We propose to develop a DTED compression and processing system based on these successful new ideas, investigate the mathematical characteristics of DTED, provide rigorous analysis on suitable data structures and metrics, and assess achievable levels of compression. We will demonstrate the utility of this system on ONR sponsor directed DTED applications. This research will lead to a software system for the efficient compression and processing of DTED in a way that preserves important terrain information, is artifact free, guarantees geographical and topological accuracy of the compressed data, and enables efficient reconstruction as well as direct exploitation of the compressed data. The system will be demonstrated on ONR sponsor supplied DTED. DoD applications include mission planning, tactical visualization, strike and post-battle assessment while integrating DTED with other sensor data. Commercial applications include image/video compression tools combined with related processing techniques. Markets for this include streaming video on the Internet and transmission, storage, and retrieval of digital images, for example in digital cameras.

Title:DTED compression guided by preservation of quality statistics
Abstract:Vexcel is proposing to work jointly with SAIC-Tucson, which maintains the evolving JPEG-2000 standard, to develop a compression standard for digital elevation models. The standard will exploit the statistics and characteristics of DEM data to achieve a high rate of lossless compression. Lossy compression formats will preferentially preserve the underlying shape and slope of terrain. Measures to be optimized will include NIMA's standard metrics of DTED quality, the relative and absolute accuracy (LE90) statistics. The proposed transmission data structure reflects the goal of maximizing DTED quality at each stage of transmission and reconstruction. Quality-controlled storage and transmission of DTED data will be useful in applications demanding remote transmission of terrain data, or storage in and access to such data from embedded environments. Potential customers include users of digital terrain data in GIS, makers of self-guided systems (e.g. UAVs), and telecommunications firms needing ready access to quality-controlled digital terrain and building models.

Title:Modeling and Simulation of Decision-making Under Uncertainty
Abstract:The primary objective of the proposed Phase I research is to develop a detailed and comprehensive design for a suite of software tools that will both accurately simulate human reasoning under uncertainty and time stress in real-world environments and support insightful interpretation of it. The design will utilize the results of research on human decision making processes in real-world settings, as well as recent developments in the implementation of cognitive architectures for modeling uncertainty. The second objective is to explore and evaluate specific decision domains, as potential testbeds for more extensive development both in Phase II and in Phase III. The third objective (which would be accomplished in the optional task) is to produce a small-scale demonstration system that helps us verify and evaluate selected capabilities in a limited but realistic decision making sphere. We will pursue the Phase I objectives in four tasks, which will advance the system through a successively more refined series of design stages: (1) Develop of a framework of constraints and assumptions that will guide the design process, based on theoretical and empirical findings on uncertainty and the potential requirements of system users. (2) Develop a cognitive-level system design that integrates a rapid reflexive inference engine, higher-order reflective problem-solving strategies, and a graphical use interface (GUI). (3) Develop software-level design, including agents and algorithms to accomplish each of the cognitive functions. (Option task 4) Implement selected system components for purposes of demonstration, testing, and evaluation. The proposed technology for simulating uncertainty has a wide range of uses, in training, decision aiding, and evaluation of equipment and procedures. Rapid change and uncertainty in the business and military environments have made decision making under uncertainty a highly prized skill at all levels. We will actively pursue commercial and expanded governmental sales of the decision making simulation tools developed in Phase II. Commercial customers may include airline pilot training, air traffic control, nuclear power plant operation, law enforcement, hospital emergency room physicians, business executives, financial traders, strategic planners, and many others.

Title:Modeling and Simulation of Decision-making Under Uncertainty
Abstract:To be successful in representing human behavior in military systems, models must reflect uncertainty and stress, decision- making at multiple levels of aggregation or expertise, complex behavior scheduling, and realistic communication behavior. Developing a modeling technology that supports all of these is the goal of this research. To date, several strategies for modeling human behavior have been successful in limited applications. However, modeling humans under stress who must make complex tactical decisions with uncertain data is still a modeling challenge. Naturalistic Decision Making theory accounts for many of the outstanding factors, but we are just beginning to develop the computational methods to support modeling the NDM process. In this project, we build off of our NDM modeling research along with other projects where we and others have developed tools to model human information processing, knowledge, pattern recognition, workload, and response to environmental and task stressors. We will focus our development activities based upon an analysis of the goals and constraints of the intended users of this modeling tool. The result of the SBIR will be a commercial-quality software package that provides the power of modeling complex human behavior under conditions of stress and uncertainty. First, we will be able to model human decision making and performance more realistically. This will allow the Navy to make better acquisition decisions and design more realistic training environments. Second, by modeling and testing a scientific theory of human decision making, we will be able validate the model and gain insight into how humans make complex tactical decisions under stress and with uncertain information.

Title:Low-Distortion Microwave Active Filters
Abstract:In multi-function RF systems combining functions of radar, communications, electronic surveillance and others, frequency agility and frequency selection are critical parameters. In terms of components needs, fast switching frequency synthesizers and low-distortion variable bandwidth, tunable filters represent critical items. Realization of multi-function systems concepts will depend on size/cost of those critical components. Hittite Microwave Corporation has pioneered in the development of active filter concepts and demonstrated active microwave filters built into MMIC chips. This proposal extends Hittite's active filter concept and describes Hittite's approach to higher dynamic range, broader tuning range, bandwidth adjustment, noise reduction, and other pertinent filter properties. MMIC filters will remove one of the main obstacles to the higher scale of integration of the microwave front-end in nearly all microwave systems, and therefore, will have a significant impact on ultimate size/cost of both military and commercial microwave systems, including portable terminals for commercial wireless systems. MMIC filters will allow complete integration of RF front-end functions into a chip in commercial communications terminals, such as cellular handsets. The market for handsets alone amount to 200 million per year world wide. Filters are used in nearly all commercial (as well as military) microwave systems, and MMIC versions may also be marketed individually as low-cost commercial products.

Title:Backside Illuminated UV Photodetectors Based on AlGaN Wide Bandgap Semiconductors
Abstract:This program will develop compact high solar blindness, high sensitivity and low dark current ultraviolet photodetectors based on AlGaN wide bandgap semiconductors, utilizing the unique properties of AlN materials for device substrates. Kyma Technologies, Inc. and EMCORE Corporation will utilize collaborative efforts of materials development, device fabrication and characterization, and device modeling, to enhance the performance of AlGaN/GaN photodetectors. For discrete, conventional photodetector structures such as p-i-n devices, this will include improving the signal-to-noise ratio and the quantum efficiency, reducing the dark current, and introducing avalanche gain. This will be achieved by reducing both the defect densities and impurity levels in the AlN substrates. The development of an AlN substrate technology is proposed to achieve improved performance and increased functionality in III-N p-i-n photodiodes. Utilizing a proven high rate material transfer process, Kyma Technologies will fabricate thick, low defect density, free-standing AlN substrates. The nitride MOVPE growth and device design expertise at EMCORE will be employed to grow UV photodetectors on this substrate material. The initial focus in this program will be the development of high-performance AlxGa1-xN p-i-n photodetectors operating in the important wavelength range of < 270 nm, where the greatest interest for military and space-based applications exists. The UV photodetector described in this program will take advantage of the unique properties of AlN substrates. First, the AlN substrate is transparent to the wavelengths of interest. Therefore, the device can be designed such that the detecting material or junction can be directly illuminated through the substrate (backside illumination), avoiding illumination though light absorbing layers, such as p-contact layers. This will allow detection of shorter wavelengths in the solar blind part of the spectrum. Second, the AlN substrate has structural and thermal properties that will improve the GaN and AlGaN layers in the device structure. These improvements should increase the commercialization of these devices in many markets.

Title:Solar Blind AlxGa1-xN Ultraviolet Photodiodes by Lateral Epitaxial Overgrowth
Abstract:The objective of this Phase I program is to demonstrate the feasibility of the lateral epitaxial growth (LEO) of AlxGa1-xN by MOCVD for solar blind, high responsivity, low dark current, ultraviolet photodiodes with a cut-off wavelength <270 nm (i.e. Al>43%). The technical challenges in this endeavor find their roots in the improvement of the AlxGa1-xN material quality, i.e. the quasi elimination of the dislocations. The LEO patterning technology, the LEO growth conditions and the device processing steps will be optimized to achieve these objectives. The materials will be characterized through x-ray diffraction, atomic force microscopy, scanning and transmission electron microscopy, photo-luminescence, Hall measurements. P-i-n ultraviolet photodiodes using low defect AlxGa1-xN epilayers grown on LEO GaN or directly LEO grown will be fabricated and measured. The device electrical and optical performance will be benchmarked in terms of dark current, solar blindness, responsivity, external quantum efficiency and detectivity. The results will be compared with those from identical detectors fabricated using standard non-LEO technology in order to address the potential of the proposed LEO technique for higher performance solar blind ultraviolet photodetectors. The solar blind ultraviolet AlxGa1-xN photodiodes using the LEO technology developed here will outperform currently existing ultraviolet devices (in terms of reliability, sensitivity and ultimate system cost) which are insufficient for the demands of DoD missions such as missile warning systems. Such devices would also satisfy the demands of flame detection, pollution monitoring, chemical reagent detection/analysis applications. The technology will have the far reaching result of demonstrating a methodology for quasi defect free AlxGa1-xN wide bandgap materials, which will be the cornerstone for a wide range of III-Nitride based commercial and defense electronic applications, including high power and high temperature electronics.

Title:Multi-Use Low Cost, Integrated, Temperature/Conductivity Sensor
Abstract:The goal of this program is to extend the Navy's tactical and research measurement capability by developing and field testing advanced low-cost versatile in situ oceanographic sensors. Specifically, the program is aimed at developing a small, robust, low-power sensing device, integrated on a single ceramic substrate, which will simultaneously measure temperature and electrical conductivity at the same location, with sufficient accuracy to reliably determine sound speed and seawater density, environmental parameters crucial to ASW and mine warfare. Each self-contained sensor module will digitize its signals, and route the signals onto a universal bus structure. The device can be produced inexpensively using automated methods and will be capable of being deployed, with only minor customizations, in expendable formats as well as moored, towed, or hard-mounted to vehicles, such as AUVs, UUVs, or submarines. Under Phase I, Aret Associates will design and demonstrate all the requisite sensor technologies on the ceramic substrate, fully tested with a functional-prototype breadboard analog circuit. During Phase II, this analog circuit breadboard, along with the digitization/communication circuitry, will be developed into a single hybrid-chip-sized circuit element; fabricated into a number of fieldable prototype units; and tested under realistic conditions in the ocean environment. This new sensor technology will drastically reduce price and increase the reliability of today's commercially available Expendable Conductivity, Temperature, and Depth (XCTD) sensors. This technology will allow the industry to move away from the costly hand-made, singly produced sensors now on the market to an enhanced-capability sensor produced using automated methods.

Title:Four dimensional (4-D) Atmospheric and Oceanographic Instrumentation
Abstract:We propose to develop the requirements and initial design for an inertial measurement unit (IMU) to aid in the measurement of physical METOC variables. The IMU can be part of a motion sensor module which can be deployed as an expendable, autonomous vehicle to measure fluid motion directly in either the oceanographic or atmospheric medium. The IMU effort centers on the requirements for the total integration of gyros and accelerometers as well as electronics on a single chip. The products developed in Phase III will be of direct use in government programs such as ERGM, WCMD, Land Warrior, and all programs that require MEMS inertial sensors. Commercial and consumer applications include: headsets for computer-based interactive training and entertainment ("virtual reality" applications); man-portable systems for navigation in hostile environments, such as firefighter safety systems; and other applications for stablization tracking and location-determination.

Title:A 4-D Fine-Scale Acoustic Doppler Current Profiler
Abstract:This Small Business Innovation Research Phase I project will address the need for a 4-D fine-scale doppler current profiler. Oceanographers are currently faced with the problem of extrapolating 1-D and 2-D current measurements to fit 4-D models. Data spikes or un-correlated measrments due to thin layers are difficult and sometimes impossible to explain. Other phenomenon such as coastal jets, which are large volume mixers, can simply not be measured with existing instrumentation. The new instrument proposed here, termed VADCP for Volume Acoustic Doppler Current Profiler, will address these issues. The advantages resulting from a special array geometry and beamforming method will provide a low-cost, low weight solution that can model fine-scale volocity structure in 4-D, providing absolte velocity measurments in a gridded volume that could reasonably be 100 meters on a side and 50 meters deep. This project will encompass a proof-of-concept phase using existing equipment previously developed by the proposer, a feasibility study for developing VADCP, and the development of a set of design performance models that will be used in the production stages of this project. The SBIR Phase I funds would be the enabling vehicle that will determine the feasibility of building a low-cost 4-D phased array doppler volocity profiler. It is expected that this system would ultimately be used to characterize volumetric velocity fields in a diverse array of applications in coastal oceanography.

Title:Integration of Advanced Magnetic Sensors into Underwater Vehicles to Provide High-Quality Spatiotemporal Magnetic Data
Abstract:Ultrasensitive magnetometers have demonstrated their responsiveness to Navy needs ranging from basic science (ocean floor geomagnetic surveys) to military operations (detection, classification and localization of buried mines). Taking advantage of their sensitivity requires means to suppress noise caused by sensor motion in the earth's magnetic field. An additional problem with using magnetometers on an Autonomous Underwater Vehicle (AUV) is magnetic interference generated by the AUV itself. A unique new instrument, the Room Temperature Three Sensor Gradiometer (RTG), developed by IBM, Quantum Magnetics and the Naval Coastal Systems Station, lends itself especially well to solving the AUV interference problem. It offers unprecedented potential for magnetic measurements of high sensitivity from AUV platforms for both research and military operations. In Phase I, we propose to characterize the magnetic interference field of low-cost, plastic-body AUV's and to use the information to design a generalized RTG optimized for AUV operation. In Phase II, we will fabricate, integrate and demonstrate the RTG aboard an AUV. Room Temperature Three Sensor Gradiometers (RTGs) integrated into small, inexpensive AUVs offer a new capability in sea floor geological research and military operations such as shallow-water mine reconnaissance. The generalization of RTG technology proposed here allows implementation in new application areas such as magnetic detection of corrosion and biomagnetometry.

Title:High Performance Optical Fiber-Based Meteorological Sensors
Abstract:This effort seeks to explore designs for fiber optic meteorological sensors and examine issues in their design and deployment. Performance data on several novel optical fiber sensors suitable to meteorological use will be presented. Current meteorological sensors and sensor suites used for weather and environmental monitoring are based primarily on electronic and electro-mechanical sensors. Installations are frequently susceptible to destruction and/or interruption from salt corrosion and lightning. In addition, especially aboard ship, local sources of electromagnetic interference from surveillance RADARs create severe problems. The cost of replacement or shielding of these systems is high, both in terms of frequency of replacement and the incipient capital cost. Pure optical or opto-mechanical environmental sensors are described that could allow the development of full meteorological instrumentation suites based on individual or multiplexed optical fiber sensors. Sensing functions which can be implemented using optical fibers include wind speed (cup anemometers & Doppler LIDARs), wind direction (vanes & LIDARs), temperature, humidity, barometric pressure, accumulated precipitation and precipitation rate (fiber LIDAR). Suites of sensors with little or no electronic or metal components in the environmentally exposed regions will eliminate EMI/EMP susceptibility and add functional capability. Current manpower reduction initiatives within the US Navy demand the improved maintenance record and price/performance ratio this technology will deliver. We feel this market is worldwide and potentially represents a "must have" replacement technology for a very large installed base of meteoroligical stations, at least many thousands of systems per year. DoD would gain optical fiber-based, ultra-reliable, EMI/EMP-proof meteorological systems for ship and ground stations use (e.g. ASOS) that will lower its total cost of ownership. We will also provide the atmospheric research community with an important new tool capable of significantly higher performance than existing technology, and even of operational capability not available today. For example, with proper optical multiplexing the technology could provide a distributed wide-area wind measurement system across an airfield or carrier deck, potentially at very low cost.

Title:Heavy Power Transmission for Positioning and Actuation
Abstract:Foster-Miller and MIT's Field and Space Robotics Lab are currently engaged in a concept study under contract with NAWCADLKE for a Shipboard Weapons Loader. The study has produced a concept design for a small-footprint, omnidirectional, human-amplifying device which interfaces with existing transport equipment and handles 100 percent of current shipboard loading tasks. Due to clearance issues with the transport equipment, adjacent-stores and landing-gear, the size of the robotic manipulator is tightly constrained. This is especially true for the end-effector which requires four rotary degrees of freedom. Actuating the end-effector is a major design challenge due to the severe torque, power and accuracy requirements and limited package size. While these requirements are within the range of commercial hydraulic technology, this approach has a major impact on system complexity and maintenance cost. For this SBIR, we propose to explore actuator technologies to provide the necessary torque and power density without the maintenance problems of hydraulics. These technologies include the following: electric-motor/gearhead, air-motor/gearhead, novel electric motors with intrinsically high-torque/low-speed, seal-less hydraulics, mechanical transmissions, and motors based on "smart materials". Assuming a promising solution is identified, Phase II would involve the development, testing and demonstration of a robotic manipulator based on the new technology. (p00451) Despite the need for pumps, reservoirs, filters, servo-valves etc., and high maintenance requirements, hydraulic systems are currently preferred for most applications requiring high-torque/low-speed in a compact package. If a viable alternative can be found, the potential market is huge. Hydraulics are used extensively in a wide range of industries including shipping, warehousing, mining, manufacturing, earth-moving, and transportation. Depending on cost, a new actuator technology might find its first use in sensitive environments, or for precision manipulation of heavy payloads. With mass production (and lower cost) the new technology would begin to replace the full range of hydraulic applications.

Title:Quadruped Robotic Manipulator as Multipurpose Positioning System
Abstract:This proposal describes an approach to building a Quadruped Robotic Vehicle (QRV) for use as a heavy-lift, stable, reconfigurable, omnidirectional, naval multipurpose mobility platform. The QRV will be able to maneuver both below-deck and on-deck in a way that could never be achieved with a wheeled vehicle. For use below-deck, the QRV could move down narrow passageways and through elevator doors easier than existing forklift vehicles. The QRV can fold to a low profile for easy storage. On-deck, the QRV could step over tie-down chains, over or around aircraft landing gear, and maneuver its payload in tight spaces near aircraft pylons. In addition, the QRV provides a mulit-DOF motion base for manipulators, end-effectors, and tools to assist in the loading and off-loading of payloads. The QRV we propose exploits four legs, each configured as a Stewart Platform. In previous work, we simulated the dynamics of such a vehicle. In this work, specific shipboard applications will be identified and the simulation will be enhanced to demonstrate the QRV's capability of performing each application. The most immediate application of the work proposed is an omnidirectional, multipurpose mobility platform for material handling and for logistics support. The QRV would be ideal as a mobility base for a robot in any application where the ability to move in tightly constrained areas is important.

Title:A Facile Alternative Synthesis for Amino-Substituted Poly(phenylene Vinylene) Derivatives
Abstract:This proposal describes a straightforward and facile alternative synthesis of amino-substitued poly(phenylene vinylene) (BAMPPV) polymers. While BAMPPV polymers show a great deal of promise as corrosion-inhibiting coatings, their evaluation and application have been hampered by limited material availability. The new BAMPPV synthesis described herein is a three-step, well-precedented procedure that should be highly amenable to large-scale production. The program will demonstrate and optimize this new BAMPPV synthesis and 1 kg of a particular BAMPPV derivative will be prepared and supplied to the Navy for further testing. The proposed synthesis of the amino-substituted PPV derivatives will dramatically lower their production costs, making them more cost competitive in conducting and corrosion-inhibiting applications.

Title:Conjugated Polymers for Corrosion Inhibition
Abstract:Spectra Group Limited's (SGL) contribution in responding to N00-079 is the development of a new, benign, cost effective synthesis of poly[2,5-bis(N-methyl-N-alkylamino)phenylene vinylene]. Replacing the low yielding polymerization step in the current synthesis is the main objective of this proposal. By finding alternative routes to this step, many of the toxic reagents that are used in the original synthesis are avoided and replaced with safer, more benign options. The proposed synthesis is designed in such a way that many different types of polymerization reactions can be attempted based on a few simple easily made precursors. This versatility should allow a good number of options to be explored while spending minimal time in the laboratory preparing precursors. The anticipated benefit of this proposal is the development of a benign cost effective synthesis that can readily be scaled up to a commercial level. The ready availability of conjugated polymers would be of significant interest to the public and private sector.

Title:Low Thermal Conductance Torque Tube System
Abstract:The U.S. Navy and private industry are investing heavily in several ship electric drive systems including the High Temperature Superconducting (HTS) ac synchronous motor system, the Superconducting Homopolar motor and the Permanent Magnet (PM) motor. Composite drive shafts with optimized high torque end fittings hold promise for significant weight reduction. In the HTS ac synchronous motor these shafts are necessary to minimize heat leak to the rotating HTS coils Foster-Miller proposes to develop a low thermal conductance torque tube system which will provide minimum heat leak for the HTS ac synchronous motor application while also bringing significant value to the other ship electric drive options. The proposed approach employs Foster-Miller's Ultrasonic Tape Lamination (UTL) technology and tape winding. UTL enables on-the-fly, net thickness placement of the prepreg and the potential for non-autoclave curing. Several innovative designs in material selection, fiber architecture and end fitting integration are presented in detail in the proposal. Foster-Miller has teamed with American Superconductor and Alliant TechSystems to bring all of the expertise necessary to address this complex problem. In this program, the team will evaluate options, develop, analyze and design a low thermal conductance torque tube system and demonstrate key aspects of its fabrication. (P-00421) The proposed program will explore an advanced composite ship drive shaft system. This will support the HTS ac synchronous motor as well as several other electric drive systems for both Navy and commercial applications. The technology development is also a major asset for composite tube development for deep water oil drilling, civil structures and other applications. Beyond tubes, the integration of UTL and fiber placement has the potential to provide a dramatic advancement in composites manufacturing through on-the-fly debulking and curing.

Title:Low Thermal Conductance Torque Tube
Abstract:Composite tubes for cold-to-warm torque, requiring low thermal conductance, for advanced ship electric propulsion systems will be developed. Composite design and material selection must be optimized to provide low axial thermal conductance and high shear strength. Space limitations, fabrication difficulties, and costs limit the diameter of the torque tubes. The use of isogrid or isotruss composite structural designs as a supplement to a solid cylindrical shell must be carefully analyzed. The incoporation of advanced fibers such as alumina liquid crystal polymers, or polyethylene will be considered. Design of thermal intercepts and the end fixtures will be incorporated into the cylindrical structure. Our plan is to use our extensive cryogenic system and materials experience combined with composite analysis to design an optimum torque tube during the Phase I base program. The Phase I optional program will continue optimization and include torsion testing of previously fabricated glass/epoxy cylinders with a quasi-isotropic lay-up to confirm analysis predictions of shear strength. The most promising alternative tube geometries defined by the base program will also be fabricated and tested. The Phase II program will include fabrications and test (torsion, axial thermal conductivity) evaluation of candidate torque tubes, first with a subsize cylindrical structure followed by scale-up to a larger diameter and length. These will include end terminations and thermal intercepts for reduce heat leak and refrigeration loading. The proposed torque tube for cryogenic motors and generators will reduce heatleak to the cold region of these machines and will greatly reduce refrigeration requirements making such systems feasible for a wide range of applications in the military and commercial sector. These tubes would also have application to a large existing market for low heat leak cold to warm supports for use in magnetic resonance imaging systems (MRI), and the storage of cryogenic fluids nitrogen, oxygen, LNG, and others.

Title:Smart Materials-based Quiet Turning and Propulsion Mechanisms for Marine Vehicles
Abstract:The need for quieting the propulsion system of naval vessels is identified Quiet turning capability and non-rotating propulsion systems are two concepts that can be employed to increase the stealthiness of ships, without the associated loss of propulsive performance. By using propellers running in variable-geometry shrouds, thrust vectoring can be achieved, in lieu of using a rudder or turning the shroud. It is also possible to create a non-rotating propulsion system that uses variable geometry to impart energy to a flow, providing propulsive power for the vessel. Both these proposed concepts utilize smart materials to effect the desired shape change. Aerotech proposes to develop two smart materials-based systems for enhancing the stealth performance of Navy ship propulsion systems: the first is a variable geometry shroud for thrust vectoring, and the second is a propulsion system that uses variable geometry to effect propulsion. The use of smart materials such as magnetostrictives and piezoelectrics offers unique advantages to designers and operators of engineering systems. Such systems can produce "solid-state" actuation, and are simple, compact, flexible, and reliable. These concepts also offer the advantages of reliable operation and increased blade life to commercial ship operators. Actuators developed for these applications can be inserted into actuation systems used in medical, aerospace, automotive, industrial motion, optics and other fields.

Title:Novel Turning Control Devices Via Smart Materials Technology
Abstract:Rapidly maturing smart materials technology can enable a new generation of turning devices for naval surface vessels. These devices will offer high-authority control for a shrouded propeller, bypassing the need for conventional rudders and the undesirable noise and vibration that can arise with current designs. The new concept involves shape control of an enclosing shroud via Shape Memory Alloy (SMA) devices. The SMA actuation technology will build on previous mechanisms that have been demonstrated in marine environments under full scale loading. Phase I will involve a preliminary sizing and assessment of an active "Smart Duct" using validated flow field models and design optimization tools. The performance of several candidate configurations will be compared and their advantages over conventional rudders quantified. This work will also set deflection requirements for SMA actuation hardware, and a first-iteration integration study will be performed to establish power requirements and response time for full scale applications. This preliminary design work will lay the groundwork for a full scale design and for scale model tests of key system components in Phase II, which will also include more detailed assessment of the impact of the new design on vibration, cavitation, and radiated noise. In addition to its potential use on naval surface combatants and next-generation submersibles, the direct uses of this technology in the marine arena are potentially widespread, since a wide range of ocean-going transports could benefit from the novel ducted propeller configuration proposed here. Indirect avenues for commercial applications would include the demonstration of a new class of very high force actuators based on SMA technology, as well as development of fast analysis tools for naval engineering.

Title:Development of a Finite Element Analysis for Failure Prediction of Large Composite Structures Under Dynamic Loads
Abstract:This proposal centers on developing an improved finite element analysis for composite structures that will allow Navy designers to more accurately predict structural failure than is currently possible. Improved failure prediction capabilities will remove a large part of the uncertainty associated with using advanced composite materials and hence facilitate more composite materials into Navy fleet use. Benefits of increased use of composite structures include reduced costs, lower weights, and reduced electromagnetic signatures. The analysis approach is a microstructural based theory and associated numerical algorithm for extracting, virtually without a time penalty, the stress and strain fields for the constituents (matrix and reinforcement) of a composite in the course of a routine structural finite element analysis. Critical components of the analysis include the ability to handle woven fabric composites exhibiting rate and temperature dependent material behavior. The finite element implementation of this theory is referred to as Multicontinuum Theory (MCT) which reflects the coexisting continua within a typical composite material. MCT is an enabling technology that provides the designer with a window into the stress/strain behavior of a composite structure at its most basic level, i.e., the individual constituents. The work proposed herein has broad commercial application. Markets for composite materials include defense, civil infrastructure, aerospace, automotive, and sporting goods. Software revenue for the finite element industry is estimated at $350 million annually. In addition, the industry is a billion dollar enterprise when consulting is included. An estimated ten percent of this total is devoted to composite materials analysis. The unique capabilities of MCT are not present in commercial codes today. The proven benefits of an MCT analysis give us the ability to penetrate the composite material FEA market on multiple fronts. Specifically, we expect to generate revenues from direct FEA software sales, sales from a proprietary material database, and consulting. Finally, results of the proposed project will benefit the Navy in the form of an accurate and efficient microphysical based failure prediction methodology for composite structural systems. The new technology will facilitate more rapid and cost effective application of new composite materials to improve performance of ship platforms and combat structures.

Title:Development of Materials and Processes that Eliminate Wear and Erosion from Advanced High Performane Projectiles & Propellants in Large Gun Barrels
Abstract:Large steel gun barrels are not only very heavy but suffer problems of poor wear and erosion from advanced high projectiles and propellants as well as fatigue life and require water cooling. The use of refractory metals/alloy liners with a lightweight titanium or aluminide intermetallic alloy structure will eliminate wear, erosion and corrosion from high energy systems and ameliorate most problems with steel barrels. Such a functionally graded materials combination can utilize a composite overwrap with water cooling or eliminate cooling as an option. The functional graded materials can be cost-effectively fabricated using rapid prototyping (RP) laser technology that is now proven to produce large air tooling and aircraft components. Lightweight refractory metal/alloy lined gun barrels that eliminate erosion, wear, and corrosion which can be cost-effectively fabricated constitute a paradigm shift in all types of gun barrels. Materials combinations will be modeled, experimentally verified, and scale model/sections of barrels produced. Rapid prototyping by laser-melt to produce refractory metal/alloy lined lightweight structural tubes/pipes will have extensive applications in all gun barrels throughout DoD, law enforcement and sports; and the processing will have applicability to produce corrosion resistant components for the chemical industry, general aerospace component's and general commercial RP parts.

Abstract:The U.S. Navy has a requirement for a low-cost, lightweight, composite outer wrapped rifled barrel design suitable for firing high-energy projectiles from the DD 21 destroyer advanced gun system. The rapid firing of high-energy projectiles using high-temperature propellants results in high dynamic barrel pressurization loads and rapid heating of the barrel. Firing high-energy projectiles also causes increased fatigue and wear on the barrel bore compared to the standard projectiles used in the current 5-inch naval gun. A novel composite outer wrapped actively water-cooled barrel design using high-performance composite materials is required to produce a gun barrel with superior dynamic strength, fatigue, wear, and heat dissipation characteristics. Texas Research Institute Austin, Inc., proposes to develop a polymer composite filament-wound outer wrapped gun barrel design that will meet requirements of the DD 21 advanced gun system. The low-cost, lightweight gun barrel will be fabricated using a proprietary, actively water-cooled, double steel liner design with a polymer composite outer wrap. Methods to increase the wear rate of the barrel bore such as using wear-resistant steels and/or high-temperature coatings for the inner liner bore will also be investigated. Development of lightweight, high-temperature, fatigue-resistant, filament-wound composites have commercial applications in the offshore oil and gas, marine, automotive, and aircraft industries. High-performance filament wound tubular components have commercial applications as drive shafts for automobiles, trucks, ships, and submarines, and as piping on ships, submarines, and offshore platforms.

Title:Autofrettage, Cooling, and Dynamic Loading of Fiber Reinforced MMC Jacketed Gun Barrels
Abstract:The DD 21 Advanced Gun System (AGS) under development for the SC 21 Ship will be required to fire at high pressures and muzzle velocity. An extended caliber barrel is required so that shipboard exit pressure limits can be met. At the required extended caliber, high specific strength and stiffness materials are needed so that the mass moment of inertia of the barrel can be minimized. Minimizing the mass moment of inertia allows a smaller barrel and generates less parasitic weight on the ship structure. Currently, monolithic materials, including high strength steel do not provide the necessary specific strength. Fiber reinforced metal matrix composite materials are required as a jacket in the barrel. The proposed program will develop a technique to swage autofrettage a metal matrix composite jacketed steel lined gun barrel. A method is proposed to overcome the low strain to failure of typical ceramic fibers used to reinforce metal matrix composite and attain the ideal autofrettage required for a long life barrel. This key development will enable the use the high specific strength MMC materials in a gun barrel jacket to take advantage of significantly improved thermal management, and signature reduction available through the use of this material. The program is expected to develop into additional applications in the DoD, including other Navy gun systems, Army gun systems, mortars, and tank barrels. Non- DoD applications include lightweight stiff gun barrels for the hunting and target shooting markets. The autofrettage process developed for the MMC material has a direct application in automotive cylinder manufacture and in the application to actuator housings for commercial and fighter aircraft.

Title:Development of a LonTalk Drive Chip (LDC) for High Performance Custom LonTalk Nodes
Abstract:Echelon LonWorks provides a very versatile and powerful development environment. However there is a need for a more powerful application processor for Neuron nodes, to handle applications where the present 8-bit neuron nodes are limited. A LonTalk Drive Chip or Core module that can be embedded along with a microprocessor core module and other support functions, into a System-on-a-Chip (SOC) has excellent potential for reducing size, power and cost, while greatly increasing performance. Providing more than one transceiver interface can eliminate the need for separate routers and SLTAs. This will further reduce the components required to implement a system. A single-chip solution for a high performance 16/32 bit microprocessor/neuron node will be very useful for many applications in the military as well as the commercial environment. The proposed LDC, along with a high performance microprocessor can reduce the hardware complexity and cost of digital equipment used on trains, as one example. Military fire control applications and other electronic systems can benefit, as the LonWorks bus can perform equivalent functions to the DOD-STD-1553B bus, including redundancy, and provide significant processing as well.

Title:Metrics for Evaluation of Cognitive Architecture-Based Collaboration Tools
Abstract:The practice of modern intelligence analysis is increasingly becoming a team effort, requiring distributed teams of experts, to collect, filter, and collaboratively fuse data into coherent responses to Requests for Information (RFI's). To quickly generate a team response, analysts must achieve a shared understanding of the problem and the best ways to assemble data for effective communication back to a consumer. Information Technology (IT) suited to the domain of intelligence analysis, will have to support new collaboration strategies that allow analysts to represent and share evolving understandings of the world, interact with data and link it to emerging arguments, and collaborate to combine related argument threads into a single response to consumers. The current proposal seeks to blend contemporary theories of team cognition with computational modeling techniques and evolving collaboration tools to prototype and assess an innovative solution that allows analysts to generate collaborative responses through the natural process of recognizing and critically evaluating the value of evidence to hypotheses about a situation. The resulting tool will help analysts focus on relevant data, help them organize data, and provide computational tools that insure coherence in final response and assess the impacts of evidence on dynamic team understanding. The results of the proposed work will be a prototype tool supporting collaborative argument construction through the natural process of critically evaluating the value of evidence to competing hypotheses about a situation. The applicability of our proposed tool can be easily extended beyond the targeted domain of intelligence analysis. At the end of Phase I we will have a functional demonstration of the tool, and will be well positioned to demonstrate the generality of our solution for other application domains, both military (e.g., military C2) and civilian (e.g., scientific collaboration, journalism).

Title:Metrics for Evaluation of Cognitive Architecture-Based Collaboration Tools
Abstract:Collaborative tools currently available provide a means for geographically and time diverse groups to meet but have not yet addressed the issues of support human cognition in the decision making process. With the engineering solution to bandwidth and data sharing over a network and with standards in place to ensure product compatability, it is proposed that the time has come to research the field to develop metrics, define the taxonomy of collaborative tools and cognitive architectures through experimentation. In this manner the measures of effectiveness of incorporating decision support aids in collaboration tools can be determined. Intelligent meeting moderator/facilitator that can access expertise and experts, provide information when needed for a decision, keep meeting members on track and help to guide the decision process.

Title:Operator State Assessment Using Psychophysiological Data
Abstract:The goal of this study is to integrate alertness monitoring algorithms we have developed during the past five years with state-of-the-art biosensor technologies (dry electrode biosensors, miniature eye-activity recording cameras) for the purpose of detecting fatigue and high workload within individual human operators of process control or vehicles. To this end, we plan: (1) to test dry electrode technology of EGI, Inc. with state-of-the-art eye movement and motion artifact removal for robust and high fidelity EEG data acquisition; (2) to demonstrate the feasibility of using a miniature video camera to track operator eye positions and extract blink rates and eye closure durations in real time to detect operator fatigue and work overload, and (3) to develop a modular design of the operator state assessment systemn for Phase II. The product of the project will be a relatively unobtrusive and completely non-invasive system that can detect periods when concentration and/or alertness of operators of process control consoles or vehicles decline. Operator state monitoring technology could prevent lapses in attention and assure most efficient use of operator's attentional capabilities in work environments such as process control consoles, security or transport vehicles, environments in which fatigue and/or poor decision-making can prove disastrous. If fatigue and workload monitoring prove feasible in real-world environments, a wide range of application environments for cognitive status monitoring of attention and situational awareness may emerge.

Title:Optimum Organization of Maintenance Aiding Information
Abstract:This project seeks to develop principled guidelines for the organization and intelligently-guided presentation of electronic maintenance documentation to support in-field maintenance aiding, and maintainer training. The goal is to utilize one source of interactive electronic technical manual (IETM) content to support both diagnostic-aiding in the troubleshooting and repair of complex machinery and training to advance novice maintainers' general maintenance and troubleshooting skills and device-specific knowledge. Our approach will leverage proven maintenance-aiding technologies, combining these with technology and insights from cognitive psychology and intelligent training-systems' design, to produce a single interface to drive a maintainer through IETM content in both instructional and decision-aiding contexts. Our approach assumes that the same technical content can serve aiding and training, if the presentation of paradigm problems and technical data as well as the nature of monitoring and feedback are fitted to the unique requirements of the interaction. At the end of Phase I we will prototype the proposed system as interactive software, and will present empirical research designs to validate our approach and explore several decision-aiding and maintainer-training themes in Phase II. Our highly-qualified team is composed of experts in cognitive psychology, diagnostic-skill training, machine diagnostics, and electronic content development and presentation. The proposed effort will result in a software system capable of leveraging a single source of system technical information found in an Interactive Electronic Technical Manual (IETM) for the purposes of interactive decision aiding and adaptive maintainer training. The technologies developed in service of this effort are based on existing standards for markup and presentation of technical information, informed by contemporary cognitive science and training theory. The result will be a general aiding and training technology that can be applied in a range of contexts, and scaled to accomodate delivery over the internet.

Title:Dynamic SuperManuals with Latent Semantic Analysis
Abstract:The object is to be able to design potentially order-of-magnitude better ways to dynamically customize information for given jobs and individual maintainers. This project will address three interrelated issues: (1) the optimum organization of maintenance-aiding information in text, (2) the presentation of the best information in the best order depending on the current knowledge and need of the user, and (3) the best handling of complex graphics under the constraint of low resolution, small-screen technology. In Phase I we propose three activities: (a) Review the literature for the last five years on design, usability, usefulness, and practical experience with systems for organizing information and for aiding and individualizing information finding for maintenance and related jobs, (b) Create partial prototypes or mock ups to demonstrate the design and intent of representative new features, functions, and enhancements based on the new computer text-understanding technology, Latent Semantic Analysis (LSA), coupled with the empirically proven design, functions and features of the SuperBook hypertext manual browser, (c) Propose a new overall design for a browser with LSA, enhanced dynamic information aids and advanced graphics functions to be prototyped and evaluated in Phase II. Maintenance of increasingly complex technological systems is a critical and difficult problem for defense, government and private sector organizations. Traditional print media and current on-line systems are not adequate. The expected outcome of this project is identification of the optimum organization and presentation of maintenance information in job-aiding, and design of potentially order-of-magnitude better ways to dynamically organize, present, and customize information for given jobs and individual maintainer levels of expertise. A successful technology of this kind will be the basis of a high revenue Internet-based service and licensing business, and will result in major cost savings and product improvements for a wide spectrum of large industries, from telecommunications to computer and network systems to airline operations.

Title:Compact, Light Weight Color Night Vision Goggles
Abstract:TeraOps Corporation proposes to develop techniques for reproducible coloring of nighttime imagery and to implement a color night vision device based on TeraOps' powerful CNN array processing technology. In addition to CNN, the unit will combine other state-of-the-art technologies including miniature image intensifiers and high-contrast head mounted displays to create a low-power, portable unit that meets operational requirements. TeraOps will exploit the unique architecture of the CNN supercomputer-on-a-chip and its more than 10 to the 12th operations per second computing speed to implement the developed algorithmic techniques in real-time. These spatial-temporal image-processing algorithms will perform enhancement and adaptive, reproducible coloring of night imagery input through the integrated multi-band sensor. The algorithms will draw upon studies of biological image processing as well as on CNN models for color constancy and color visualization developed earlier by TeraOps researchers Colorized night vision goggles will greatly enhance the navigational and target recognition capabilities of military personnel. Color night vision units are expected to be of significant use for commercial aviation, police, rescue, and other civilian surveillance applications. Moreover, the CNN computer is a general- purpose machine that can be programmed to perform a variety of sophisticated image processing functions. The development of the CNN-based image processing engine will facilitate the development of products for real-time medical imaging (ultrasonic, MRI, CT, etc.), high-resolution displays, augmented reality systems, "smart" video cameras for automatic image acquisition, etc. The CNN computer will also be applicable to high-speed image processing for multimedia and video conferencing.

Title:Compact, Light Weight Color Night Vision Goggles
Abstract:Voxtel Inc. proposes to develop and demonstrate innovative technologies for combining infrared and low light sensor that, when integrated into a lightweight, low-power, rugged, reliable helmet mounted package, will provide high information content, fused IV/IR imagery and color night vision capability. Due to the complementary nature of the spectral bands, such thermal and low light level sensors are ideally suited for image fusion. In flight demonstrations, pilots have found that fused imagery maximized information content and provided the most contrast when compared to either sensor alone. In the proposed Phase I program, Voxtel Inc. will demonstrate high information content, fused color night vision imagery. An application driven tradeoff will be performed to analyze the respective information contributions of visible (0.4 - 1.1 mm) back-illuminated CCD and (0.4 - 0.9 mm) intensified CCD cameras, NIR (0.4 mm - 1.7mm) InGaAs sensors, and uncooled infrared sensors both individually and when fused using Color Night Vision algorithms. Testing and algorithm development/validation will be performed on the existing PixelVision multi-processor image fusion test bed. A color night vision goggle concept will be developed. During the Phase I program, PixelVision, taking into consideration the state-of-the-art in technologies, will design a common aperture, helmet mounted dual VIS/LWIR Color Night Vision system with a belt mounted color night vision fusion processor that will be manufactured in the Phase II effort. Color night vision goggles would be of great value to policemen, sportsmen, surveillance personnel, FBI and other organizations requiring enhanced night vision capabilities. Variations on this design could improve drive vision in cars and trucks traveling at night, and would be particularly useful in fog or other conditions that obscure viewing but are transparent to infrared.

Title:Nanocomposite Warheads
Abstract:Today's missile targets are harder, tougher, and more likely to survive impact from the high-velocity steel shroud fragments of the Navy's current Standard Missile design. Current warheads are woefully ineffective against multi-layer, non-homogeneous target materials and configurations. Therefore, warhead performance must be improved to maintain the Standard Missile's effectiveness and insure safety of the Navy surface fleet. Recently, the Navy has undertaken significant efforts to replace steel with tungsten heavy alloy (WHA) in SM-2 shrouds. Hence, tungsten and its alloys and composites are of considerable interest for penetrator applications due to their high densities and excellent high-temperature mechanical properties. However, there are many inherent difficulties in processing and manufacturing of conventional WHA's. Based on the preliminary studies conducted by us, we will focus on nanocrystalline materials based on W-Ni-Co composites for this Phase I effort. We will evaluate the suitability of synthesizing and consolidating these nanomaterials and their impact on the performance as potential warhead materials. We will employ the hydrocode model incorporating the effects of nanocrystalline grain size, density, yield/tensile strength, etc. on the simulated warhead performance. We will also determine the effective shape, contour, and size of the liner materials to attain maximum performance characteristics. Applications include, but are not limited to, commercial and other defense ammunition, oil-well drilling, mining, construction, law enforcement, and energy industries. Furthermore these materials have tremendous commercial potential as cutting tools, mining and construction tools, die and wear parts, microelectronic packaging, counterweights, radiation shielding, high-temperature structural components, space components (thrusters, nozzles, rocket engines, chambers, etc.), aerospace components, lamp filaments, heating elements, etc.

Title:Innovative Air and Surface Strike Weapons Technology
Abstract:Sensor Technologies & Systems' personnel have over 35 years experience designing, building and testing active, semi-active and passive RF seekers for air-to-air and air-to-surface missile systems. STS has recently been working at millimeter wave frequencies for low cost ($500-2000) commercial sensor applications. STS proposes to investigate the application of this commercial technology for a very low cost air-ground seeker. This seeker would feature beam steering in aximuth for search and high range resolution for clutter rejection and target identification. STS has been engaged in the design, fabrication, and test of millimeter wave radar sensors for several years. STS was initially contracted under the U.S. Department of Transportation's Integrated Vehicle Highway System program to evaluate the effectiveness of forward-looking radars for collision warning and cruise control for future cars and trucks. This effort lasted from 1993 to 1998 and included the design, fabrication, and test of a 76.5 GHz FM-CW radar mounted on the front of a test vehicle. Since then STS has started development of a miniaturized 76.5 GHz radar for use in this application. This radar has many of the generic features which would qualify it for use as a missile seeker, such as a narrow azimuth beam (1.6 degrees), good range resolution (1.5 feet), a scanning antenna in azimuth (20 beam positions), and radar image processing for scene recognition. The radar transmits only a few milliwatts of power, yet it can easily detect vehicles over 200 meters away. While this range is not sufficient for a seeker, one kilometer should be, so the concept is worth considering. There is component development occurring in the 76-77 GHz band because of the automotive applications. STS Proposes to take advantage of this development to design and test an extremely low cost missile seeker.

Title:Technology for Shipbuilding Affordability
Abstract:In order to promote commercial competetiveness and reduce costs in the shipbuilding industry, DCS is proposing to bring into the industry a strict process control to reduce the amount of dimensional variation during the Design and Production of each ship. The Dimensional Management Procedure has been the main reason for the U.S. automotive industry's comeback in the world competitive market. Over the last ten years the US automotive industry, through the use of the Dimensional Management System (DMS), has made tremendous advances in reducing the production costs of their vehicles while at the same time achieving significant increases in quality. The DMS is a very strict and controlled process that has been able to identify design and/or process problems throughout the entire life cycle of the platform. With the use of the DMS procedure a communication network in the engineering design and manufacturing cultures has been established to reduce the products average unit cost through accuracy control and process management. The focus of this proposal is to bring this proven methodology and its associated technologies into the shipbuilding processes to positively impact the industry. - Establish the US shipbuilding industry in the World Class Market. - Reduce the average unit cost of each ship by limiting the amount of unneccessary manufacturing rework and design changes due to the results of process and material variation. - Improve production methods, production planning and control, accuracy control, supplier relations and design for manufacturing.

Title:Technology for Shipbuilding Affordability - Development of a Monitoring and Feedback Device to Increase Human Welding Productivity
Abstract:Manual, human welding is still a vital operation for shipbuilding and other large structure manufacturing. Surprisingly, the advancement of manual welding equipment has been virtually ignored. Today's experienced welders are only slightly more productive than they were 30 years ago. To compound this problem, the U.S. labor pool of welders is shrinking and less skilled welders are being utilized at an ever-increasing rate. It has become critical for shipbuilding operations, to develop technologies that will increase the productivity and cost-effectiveness of manual welding. The objective of this proposal is to prove the feasibility, to the point of demonstration, that a "Portable, Semi-Automatic Arc Welding Monitoring and Feedback Device" can be developed that will meet these goals. This device will significantly reduce manual welding costs by increasing its speed and accuracy, and reducing the amount of rework required. Additionally, a real-time feedback feature will provide extra sensing capabilities, allowing less skilled, lower paid welders to produce quality welds. This device will also reduce welder training time, and will generate electronic audit trails for process time and parameters. By providing real-time process feedback, the human welder instantly knows if the weld being performed is accurate and within the established quality guidelines. This instantaneous process knowledge allows the welder to take corrective action before a bad weld is produced. This capability has many benefits that all lead to production efficiencies, cost reductions and increased quality. Productivity Increases are gained since the welder is going to be more accurate, and will spend less time reworking previously welded parts. Due to the high degree of rework currently being performed in U.S. shipyards, the production efficiencies created by this device, will also shorten the overall production time of ship construction. This device will also allow welders to work more effectively in situations where the weld is not easily accessible, or possibly even hidden, or when the weld is in a hazardous location. Cost Reductions are gained in several ways. Since the proposed device will greatly reduce reworking, the additional costs of welding consumables as well as labor costs will also be reduced. This device will make a good welder better and a poor welder good by adding sensing capabilities, so another cost reduction comes via the shipbuilder's ability to rely on less experienced and thus, lower paid, welders to get the same job done. Another cost reduction is due to the shorter training time required to make new welders productive. The instantaneous feedback allows welding students to learn at a rapid pace. Quality Increases are also gained in several ways. The real-time information being fed back to the welder gives them an ability to take corrective action as they weld. The skill set of less experienced welders will be enhanced to make them better welders.

Title:Convertible Floating Dock
Abstract:There are problems that both the Military Sealift Command (MSC) and commercial ferry systems have, which this dual-use design addresses. Sealift problems realized during past military conflicts have spawned ongoing studies with respect to commercially viable additional vessels and faster vessels. One of the logistical problems encountered by these vessel concepts is the "hurry up and wait" syndrome. The cargo handling surge that occurs during wartime in U.S. and foreign ports or the non- existence of ports in the theater or war, creates a sealift bottle neck. The Mobile Offshore Bases (MOBS) concept was devised to address this issue on a grand scale but has not proven to be financially feasible. More recently, the military has embarked on the Joint Modular Lighter System (JMLS) program to develop modular docks, both motorized and non-motorized, for supporting sealift Joint Logistics Over The Shore (JLOTS) operations . Floatable Docks which could be mass produced for both military and commercial applications, and are therefore highly affordable, can be moored with the Ready Reserve Fleet in strategic locations around the world and towed into the most logistically desirable locations when and where a military conflict arises. Because of the exploding market demand for ferries, and consequently more ferry docks, as well as the potential military market, the time is right for a Convertible Floating Dock to be developed, to meet the demand. The combined factors of market demand and the Convertible Floating Dock features, indicate that there exists a maritime industry opportunity for a product design breakthrough, which provides a highly flexible and economical system for commercial and military (dual-use) markets. Developing such a design, which could leapfrog the U.S. as a global competitor in dock system production, is commensurate with the MARITECH ASE Advanced Product Designs and Materials Sub-Initiative, under the Product Design and Material Technologies Major Initiative.

Title:Reducing the Cost of Naval Vessels through Use of Inexpensive, Lightweight Structural Foams
Abstract:Within focus on Product Design and Material Technologies under MARITECH's Strategic Investment Plan, there is opportunity for development of novel materials and designs that will reduce systems costs and offer performance improvements. A technology, based on domestic materials and expertise, is being developed by Touchstone Research Laboratory that will support low-cost shipbuilding and market differentiation with international shipbuilders. It is a lightweight, fire-resistant, structural carbon foam produced from readily-available bituminous coal. Carbon foam advantages that support shipbuilding affordability include (1) finished component costs projected at less than $6 per pound, (2) widely available precursors from a robust, domestic supplier base, (3) parallel development for commodity industries to reduce manufacturing costs with increased volume, and (4) reduced maintenance/replacement costs in a marine environment. Initial concept testing has been supported under Navy Phase I and II SBIRs aimed at illustrating the multifunctionality of carbon foam. There are many naval applications for carbon foam, utilizing its structural properties and fire and corrosion resistance. In the proposed effort, Touchstone seeks to broaden exposure of carbon foam to include other vessels, such as submarines and smaller surface vessels which also offer applications for lightweight, inexpensive, and fire resistant structural materials.

Title:Technology for Shipbuilding Affordability
Abstract:Vexcel Corporation proposes to adapt, and expand, its existing close range photogrammetric process, currently in use by aerospace, automotive, military, and process plant designers, to the unique applications of shipbuilding construction. This technology will have immediate benefits in the MARITECH ASE major initiative areas of Shipyard Production, Systems Technologies (simulation), and Facilities and Tooling. The process allows for highly accurate 3D measurements and 3D models (scene reconstruction) to be extracted from digital photography. The process requires no in field targeting of points of interest, and uses random hand held photography. High accuracy, and automated element extraction, is obtained through the integration of extensive image processing capabilities. In cooperation with Bath Iron Works, the process will be adapted and applied to accuracy control and 3D modeling in Run-to-Suit applications, joining of modular units, and Foundation Verification. Optionally, and in Phase II, Vexcel will produce an enhancement to the existing process, allowing for the fully automated 3D modeling of piping direct from random hand-held digital imagery, or video. There is a large demand in the shipbuilding industry for rapid, high accuracy three- dimensional as-built information to support retrofit design, damage assessment, construction verification, modular component verification, and run-to-suit documentation. Currently, these requirements are handled through labor intensive applications, reducing production efficiency through costly downtime, fabrication interference, and incomplete data. Having a automated 3D as-built modeling application will improve shipbuilding efficiency, expand simulation capabilities, and support efficient use of support facility layout and design. The great commercial potential for the proposed system is driven by the wide array of applications dependent on receiving timely and cost effective 3d models of real world environments. The range of potential applications include industrial photogrammetry, telecommunications, urban planning, real estate development and sales, retail sales, machine design, parts verification, forensics, and virtual reality based entertainment systems. All of these application areas have growing needs for three dimensional models of the real world, either for engineering applications or for use in virtual reality simulators. Additionally, the significant reduction in on-site labor to acquire field measurements this system could provide increases the commercialization potential through risk reduction in environmentally hazardous areas.

Title:Combat System Automated Testing
Abstract:Current Navy regression testing methods for COTS based systems are labor intensive and expensive. This proposal describes a method for substantially automating the regression-test process for distributed-object shipboard systems: the CORBA Environment Regression Testing System (CERTS). CERTS Software addresses of test/certification functional testing, real-time response measurement, and availability factors for COTS-based CORBA systems. CERTS significantly reduces the time expended on regression testing CORBA systems by allowing the test engineer to quickly record an existing, certified CORBA system's behavior and to subsequently use this behavior model as a comparison baseline for future upgrades. When a new implementation, or upgrade, of a particular distributed system is inserted into the CORBA environment, CERTS stimulates the new system, captures the new system's responses, and compares these responses to the behavior modeled in the baseline. By highlighting deviations from the baseline, CERTS provides the test engineer with the ability to quickly determine where regression test failures occur or if the new system is functioning correctly. Since CERTS automatically generates it's own testing scripts from network conversations, additional time is saved by allowing the test engineer to concentrate on certification rather than the tedious process of writing and debugging test scripts. CERTS will benefit test engineers who are involved in the regression test of distributed object systems by significantly reducing the time required to develop and execute regression tests. While the primary focus of CERTS is for shipboard and submarine-board distributed system testing, the technology is applicable to any COTS distributed-object environment. CERTS will extend Architecture Technology Corporation's existing commercial protocol-analysis tools and system simulators with added test/measurement features.

Title:Modular Blocks for Modular Cells
Abstract:Power electronics requires a system that has the flexibility and design space that semi-custom logic has in digital electronics. The Modular Blocks for Modular Cells concept offers this design power, using the concept of a cellular power bus, it provides a semi-custom module using modular sub components. Since the cellular power bus and its supporting structure conform to a standard X & Y size and repeat, it is possible to define the outline size for the sub components that mount inside the cell. If the interfaces inside the cell are defined it now becomes possible to create modular sub components that can be mixed and matched to create semi Standards based design provides the basis for a new industrial model for the power electronics industrial base. A network of companies working cooperatively but in their own areas of specialization to provide the standardization, infrastructure, and production capabilities required to meet the needs of the power electronics customer base. The modular blocks would meet the needs of the Navy and other services for power electronics systems that are quick to develop, reasonably inexpensive and supportable over long periods of time.

Title:Fast-response Sensor for the Measurement of the Optical Properties and Carbon Content of Organic Aerosols
Abstract:Droplet Measurement Technologies, Inc. proposes to demonstrate the viability of a new technique for measuring carbon mass on a particle-by-particle basis. The methodology utilizes a combination of light scattering and emission to differentiate carbon aerosols from other types of particles and quantify the mass of these particles over a size range from 0.05 micrometers to greater than 5 micrometers. The technique will measure carbon mass with three orders of magnitude greater sensitivity and response time than currently available measurement techniques. The proposed measurement technique will have applications in the areas of air quality research and monitoring, combustion research, health studies, and climate change research. The high sensitivity and fast response time will make the technique ideal for atmospheric studies of how soot impacts health, air quality and climate in urban, tropospheric and stratospheric environments.

Title:Real-time Interactive Analysis and Visualization Interface for Environmental Research Data
Abstract:Mission Research Corporation (MRC) proposes to design and develop a prototype system architecture to perform remote sensor control, data acquisition, dissemination and display of real-time observational data, utilizing Internet and SATCOM technologies. The objective is to support cost-effective environmental research activities that do not require participants to be physically present during field deployments. Capabilities will include a web-based graphical interface, with appropriate security measures, allowing remote investigators to interact with the data collection system over the Internet. An optional SATCOM link will be developed to support operations for cases in which direct Internet access to the data system is not feasible. Interactive capabilities will be developed to disseminate and display user- configurable volumes of real-time data from multiple sensors to multiple remote users. The system will also process and filter up-link commands to instruments during field operations, and allow user feedback to be provided on the operational status of the sensors, data link, and aircraft. Under the Phase I effort, MRC will design and develop preliminary capabilities to perform these functions. MRC will integrate and test these prototype capabilities for sensors used by CIRPAS for environmental research. If the Phase I option is funded, MRC will continue to implement and configure preliminary system capabilities and provide demonstrations to potential Phase III customers. This effort will provide the foundation for Phase II development and demonstration of a fully capable system for remote sensor control, data acquisition, management and visualization via the Internet and an optional SATCOM link, for use in multi-sensor and multi-user field experiments. The system is to be used by CIRPAS and their customers for environmental research using remotely-piloted aircraft. DOE, NASA, NOAA, NSF, and NCAR could also use the proposed technology for collaborative research programs using aircraft, ships, buoys and other data collection platforms. Private sector applications include use by Droplet Measurement Technologies for remote data acquisition and control of their particle spectrometers and by Pacific Sierra Research Corporation for remote monitoring of airborne radionuclides near reactors and production facilities.
