Title:Reliable Captive Structural Panel Fasteners
Abstract:This SBIR proposes the development and demonstration of a captive panel fastener that can transfer shear loads; has a high fatigue life, low failure rate, low weight, and high reusability. The panel fastener will work in composites or metals and be impervious to environmental effects, while maintaining captive properties to reduce the risk of foreign object damage (FOD). The new panel fastener will not require modification of the V-22 structure. The Operational Evaluation report will be used as guidance, in addition to the Reliability and Maintainability data which has been accumulated to date, to determine the failure modes of the fastener. All the components of the fastener assembly will be analyzed to assess which are functioning properly, and identify those, which need to be further, developed. The functioning, and interaction of the individual components will be studied carefully to establish design configurations which will be more reliable. Geometric and material changes will be considered to provide the added performance. Analyses will be performed as necessary to assure that the joint strength and fatigue life will not be adversely affected by the modifications. Testing will be conducted to determine the optimal modification and demonstrate that it out performs the production configuration. The requirements for modern and future commercial aircraft should not be any more demanding than the V-22. Composite materials are being used more widely in the commercial sector also. This fastener will be readily adaptable to any commercial variant, and will provide the same benefits of improved reliability, and availability for commercial aviation as it will for the V-22. As composite applications expand commercially, this fastener will have Industrial and Marine applications.

Title:Reliable Captive Structural Panel Fasteners
Abstract:Any new design must keep the hole preparation as designed for the existing fastener used in panels on the V-22 aircraft. A new fastener will utilize a retaining ring that allows positive captivation to the stud assembly as well as a positive holdout feature. This design will solve the existing problem of stud retention and retraction. The primary benefit of this research is the creation of a fastener that works as intended. Secondary benefits of this research include: cost reduction, weight reduction, increased strength, and water integrity.

Abstract:The proposed research will initially focus on the key component required for the successful development of the ACES; the non pyrotechnic power source. Phase I will test the feasability of a previously untried concept for providing clean, reliable, and low cost operation of the system. In Phase II, a complete prototype ACES will be developed around that energy source. A viable nonpyrotechnic energy source has many commercial applications. Besides, the ACES, many EMI sensitive aerospace systems could use this alternate technology. There is also potential in other marketplaces, such as the automotive airbag industry.

Title:Elimination of Galling and Fretting by Novel Composite Coatings Consisting of Dispersed Solid Lubricants Within a Ceramic Matrix
Abstract:The U.S. Navy has a critical need to develop coating technology that will significantly reduce the occurrence of galling and fretting between contacting metal surfaces found in aircraft and ship engine / mechanism components. Engineered Coatings Inc. (ECI) proposes to develop new high-performance composite coatings which offer a wear-resistant matrix (ceramic) with uniformly dispersed solid lubricants (such as soft metals or layered lattice materials), which will eliminate galling and fretting problems. Islands of solid lubricant will form, during coating, from the large difference in melting temperature between the lubricant and the ceramic matrix. These unique coatings will be produced by co-deposition, using bias-assisted unbalanced magnetron sputtering and subpicosecond pulsed-laser deposition, two deposition methods that produce coatings with excellent adhesion, toughness, wear resistance, and low-friction. After definition of U.S. Navy component requirements, ECI will select two or three candidate cermet coating systems for deposition and subsequent screening tests (adhesion, galling, fretting resistance). Down-selection to the two best performing coatings and best deposition method(s) will be performed. Design of a fixture for processing of a selected subsystem component, in vacuum, will also be conducted. In the Phase I option, fabrication and operational demonstration of the special fixture will be performed. Significant reduction or complete elimination of galling and fretting damage modes. With the addition of the dispersed solid lubricants to the composite coatings, lubricant starvation periods, during start-up and shut-down will be mitigated. These coatings also have significant potential application to industry, as coatings for can-forming operations, dry machining, mechanical assemblies, engine components.

Title:Low Temperature, Cost-Effective Application of Refractory Nitide-Based Tribological Coatings
Abstract:This proposal addresses the Navy requirement for extending the service lifetime of specialty fasteners and propulsion system components in critical aircraft and nuclear applications. Exothermics and their team members Bayside Materials Technology and Bell Helicopter Textron propose a program to develop and refine cost-effective, scalable physical vapor deposition (PVD) techniques that will modify the tribological properties of various substrate surfaces in order to eliminate or greatly reduce the tendency for galling or fretting. The surface coatings will be based on refractory nitrides such as TiN or ZrN. The tribological coatings, refractory nitride sputtering targets, and PVD coating fixtures will be fabricated by Exothermics, leveraging expertise gained from SBIR programs and commercially funded development efforts. The principal demonstrator component chosen for Phase 1 and Phase 2 is a Ti/6Al/4V drive shaft coupler used on the Bell/Boeing V22 tiltrotor aircraft. Limited amounts of wear testing using a pin on V-block apparatus would be conducted in Phase 1 to compare coating tribological behavior. Coated test coupons made during the Phase 1 will be produced by unbalanced DC magnetron sputtering and ion beam enhanced deposition methods. Both methods will permit great flexibility with regard to manufacturing scale-up, coating microstructural tailoring and substrate temperature control. Commercial markets which could benefit from products made in support of the proposed work include: (1) rotary and fixed wing aircraft drive shaft components; (2) ring and runner seal face components in naval and civilian reactor coolant pumps; and, (3) high temperature - capable electronic packaging for missile guidance systems and turbine engine diagnostic hardware. Product sales in the vicinity of $3-5 million/year within a five year period could come about - at least partially as a result of research contributed from this program.

Title:Novel Diffusion Coating for Elimination of Galling and Fretting in Standard Metal Alloys
Abstract:The detrimental effects of galling and fretting on the performance and lifetime of numerous metallic components used in military, aerospace, and commercial applications are clear. Attempts to reduce galling and fretting have been largely unsuccessful for several reasons. The addition of conventional lubricants minimizes the problem in the short term; however, by their intrinsic nature lubricants deteriorate fairly rapidly, and frequent use can create waste and environmental hazards, especially in a nuclear environment. Conventional overlay coatings applied for increased wear resistance are often not well suited for protection of the base alloy, particularly while under load, because their properties are often vastly different from those of the base alloy and the distinct coating/substrate interface can fail, resulting in cracking and spalling of the coating. To counter this problem, Ultramet has developed an extremely versatile and cost-effective diffusion coating process, in which the wear/corrosion-protective material can be diffused into and chemically mixed with the surface of various steels and superalloys and thereby become an integral part of the base component. This technology has been demonstrated for protection of high-cost precision propellant valves used by NASA, which were susceptible to acid corrosion. In this project, Ultramet will team with Bell Helicopter Textron in the development of an innovative diffusion coating material and process that will substantially extend the service life of gears used in the V-22 Osprey aircraft by eliminating galling and fretting conditions. The development will greatly expand upon previous work, which involved mainly corrosion resistance, to include full optimization of wear properties and survivability in the operating environment. The need clearly exists to eliminate metallic component failure resulting from galling and fretting. Conventional lubricants and wear protection coatings are not capable of providing long-term protection for load-bearing parts. The proposed diffusion coating material and process development effort will result in an integral coating/substrate system that will dramatically increase component service life and have extensive application in both military and commercial markets.

Title:High-Speed Dual-Mode Missile Radome (HiSMR)
Abstract:As the Navy continues to make advancements in the dual-mode RF seekers, antenna bandwidths improve and the frequency of operation continues to rise. Higher frequencies require radomes of reduced thickness, which poses a difficult radome materials challenge as the frequency of operation reaches W-Band. In conjunction with higher frequencies, higher speeds are anticipated. This creates a temperature capability issue. Higher speeds force radome materials to maintain mechanical and electrical properties at higher temperatures. Composite Optics, Inc. (COI) will work with Science and Applied Technology (SAT) to generate high speed missile radome requirements and endeavor to search out materials and processes to create a low cost, high performance radome design. There have been a great deal of material advancements over the years, and it is time to evaluate these advancements and categorize them by RF performance, thermal capability, mechanical performance and environmental suitability. COI will also evaluate manufacturing maturity, time to market, start-up cost and production unit costs. COI has experience with W-Band radomes as well as C-J band antenna performance and integration. The conclusion of a Phase I program will lead to low risk designs with potential for high performance, and low costs production of high speed dual mode missile radomes. The integration of anti-radiation homing antennas with W-Band seekers, is a problem without a proven solution. COI and SAT will perform a thorough analysis of requirements and potential solutions that will benefit all future missile designs and upgrades. The Advanced Anti-Radiation Guided Missile (AARGM), as well as the AIM 9X (Sidewinder) are potential commercial targets for such an advancement in technology.

Title:High-Speed Dual-Mode Missile Radome (HiSMR)
Abstract:The objective in this exploratory development is to identify materials and designs for a radome which will withstand the environment of high speed missiles and provide rf transparency for a low band side mounted conformal antenna as well as a W-band forward looking radar sensor. Materials, manufacturing processes, designs, cost and reproducibility will be emphasized in the study. A new ceramic material will be ocnsidered which has a lower dielectric constant than other ceramics and which is moisture impermeable. Two material systems using quartz fibers will be considered. The first uses woven socks with a high temperature inorganic polymer binder. The second uses a winding process with quartz fiber with a high temperature binder. The use of inductive grid technology and quarter wave matching layers will be considered in the designs. Upon completion of the Phase I research, one design will be selected for the Phase II development. The final design selected for further development will be based on preformance, cost and manufacturablitiy. The proposed radome technology will have potential use on high-speed missiles as a low cost replacement for present radomes and for future applications. A wide range of high temperature applications is anticipated including high temperature circuit boards, commercial cookwave, etc.

Title:Investigatioin of Diode Lasers for Removal of Large-Area Appliqu‚
Abstract:The objective of this SBIR project is to investigate and develop the capability for the removal of appliqu‚ from Navy aircraft. Appliqu‚ coatings are basically coated adhesive sheets and have been experimented with as an alternative to sprayed organic coatings but have proven to be difficult to remove using an environmentally acceptable process. Appliqu‚ coatings have been used and tested on the F-18 having adhered under Mach 1 plus conditions, and is being experimented with on the JSF. Appliqu‚ coatings are environmentally friendly as an alternative to paints, but the removal process is not environmentally safe. Currently, the appliqu‚ is removed using large quantities of solvents such as methyl ethyl ketone to soften the adhesive on the back of the appliqu‚, which generates a large amount of volatile organic compounds. LANCORP has successfully removed an appliqu‚ sample using its diode laser stripping method. Our approach is to build upon this success by demonstrating diode laser ability to remove appliqu‚ and then by designing a full-scale system for rapid removal from aircraft surfaces. LANCORP has demonstrated the ability of diode lasers, over other types of lasers, to strip and clean aircraft coatings in an efficient, controllable and cost-effective manner Effective implementation of laser de-coating technology offers the following benefits: reduced environmental impact from elimination of the use of hazardous chemicals and reduction of solid waste generated for disposal, reduced health and safety risks due to the elimination of exposure to hazardous chemicals and de-coating residues (e.g., dust from dry abrasive blasting operations.), decreased operating costs due to reduced labor, materials use, damaged parts, and waste disposal costs, enhanced capability to apply advanced coating systems, such as electrocoats and powdercoats, since the process in essence "mills" the coating off. This technology would provide a rate of stripping comparable with present methods, comparable in cost to other stripping methods, but with the added value of eliminating the need for a dedicated depaint facility, or the preparation and cleanup issues. This is a less expensive more qualitative near term technology that can be implemented within 1-2 years, since the LANCORP ASI design incorporates commercially available components into a proprietary configuration, with the tool head being the most unique part of the system. Using this technology, high power laser stripping systems can be built for under $100,000.

Title:Design and Fabrication of Low-cost composite tooling materials
Abstract:Advanced Ceramics Research Inc. (ACR) has recently developed a low-density water-soluble mandrel material composed of a hollow ceramic-microsphere filler bound together with a high thermal stability thermoplastic binder. ACR and its partners propose to use a variation of this product containing high thermal-conductivity powders for a novel low-cost tooling material for polymer composites. Preliminary experiments have suggested that this is indeed possible. This new material, can be tailored to provide a specific coefficient of thermal expansion (CTE) and thermal conductivity (TC), thus providing a tooling material that can be matched to the composite structure being fabricated. In addition, this material will be lightweight, environmentally benign, water-soluble and the cost of the bulk materials is low. Another important feature of the tooling material is that it requires no complex processing and has almost nonexistant shrinkage as the tooling material cures. The tooling technology developed in this program will have a significant impact upon the composites manufacturing community. In particular, this technology will enable more efficient, cost effective methods of fabricating composite bodies used in a whole host of industries.

Title:Rapid Tooling for Composites using Close Range Photogrammetry and Rapid Prototype Construction
Abstract:A process for producing Rapid Tooling for Composites shall be developed to meet the shortcomings of present composite tooling methods for addressing low volume applications such as prototyping and repair. The RTC method embodies two technology developments. First, a rapid noncontact method is used to capture geometry definition of the part to be produced and create an accurate and full featured 3D model. Next, the 3D model is used to create a tool (usually a mold) using powerful rapid prototyping manufacturing equipment. The resulting RTC tool is dimensionally accurate and capable of lasting at least 10 molding cycles, yet is mush less expensive and quicker to produce than conventional composite tooling. Work shall be performed by Kazak in collaboration with a major airframe OEM that has both the need and some of the specialized equipment useful for the performance of this work. Rather than simply performing a paper study in Phase I, this program includes fabrication and characterization of a small proof-of-concept RTC tool, reducing time-to-market by at least one year. The program goal is to reduce soft tooling costs for composite molds by 80% and lead time by 60% while maintaining required dimensional accuracy, low CTE and low thermal mass. For the phased depot maintenance (PDM), standard depot level maintenance (SDLM) and in-service repair (ISR) performed by the Naval Air Depots, this will result in substantially reduced cost and improved turnaround time for composite part repairs. In addition, this will considerably simplify logistics associated with ordering or producing spares from the aircraft OEM or using their tooling. For development programs such as JSF, use of RTC tooling will greatly facilitate production of prototype composite airframe prototypes. The digital nature of the 3D information capture process means that an RTC service bureau can be remotely located and serve multiple composite tool customers. These customers can include the NADEP's, airframe OEM's, airline repair facilities and other low volume fabricators such as general aviation. Furthermore, there are multiple offshoots of the 3D modeling capability including product modeling for e-commerce/website display, 3D virtual showings for real estate sales, and 3D tourism.

Title:Definition of Software Architecture in Support of Virtual Instrumentation
Abstract:This SBIR's objective is to derive functional and interface requirements for the Resource Adapter Interface (RAI) within the Standard Environment for Test as defined in the Automatic Test Systems (ATS) Subdomain Annex of the Joint Technical Architecture (JTA), Version 3.1, dated 31 March 2000. It will establish a preliminary architecture and interface requirements for the software layer between the Test Program Set (TPS) software and ATS instrumentation, while providing the necessary level of independence between these two ATS elements. This increased level of independence will enhance TPS transportability and asset interchangeability and dramatically impact the total life cycle cost of ATS/TPS ownership. Current industry initiatives are attempting to remove the test hardware dependency from test languages by providing better signal modeling capability (such as ATLAS 2000) and attempting to specify standard semantic interfaces for test assets (such as IVI and IVI-MSS). This SBIR builds on these by defining a compatible architecture, while addressing the specific issues related to major DoD ATS acquisitions. The RAI unites the signal-based world and the instrument-based world, through a layered architecture which provides adaptation layers to both the applications and the instrument layers separated by a decoupling agent. This SBIR will have the benefit of reducing the total life cycle cost of ATS/TPS ownership as well as providing enhanced test system capability and flexibility by addressing the issues of interoperability and interchangeability. It will help address instrument obsolescence issues in both DoD and commercial ATS as well as address issues related to the DoD trend towards the use of Commercial-Off-The-Shelf (COTS) equipment. It will reduce ATS development costs and also provide more efficient utilization and decreased maintenance costs of test resources developed utilizing the RAI architecture. Commercial applications include: (1) ATS development compliant with the RAI standard; (2) RAI related software products including a baseline system covering a specific set of instrumentation and test functionality as well as available options for additional capability, additional instrumentation, and instrument simulation; (3) RAI compliant applications providing complex stimulus/measurement functionality utilizing multiple COTS instrumentation; and (4) RAI related services such as verification of new instrument compliance and verification of instrument interchangeability.

Title:Definition of Software Architecture in Support of Virtual Instrumentation
Abstract:The test community, in attempting to solve test systems obsolescence issues, has been searching for ways to isolate test programs from specific knowledge of test resources. This test program decoupling from resource specific knowledge is referred to as instrument independence or instrument interchangeability. Several Commercial and Department of Defense (DoD) entities have and are working on the issue. Currently, no standardized or commonly accepted solution for completely providing the capability has emerged. The software community has made advancements in technologies that lend themselves to this need. One such technology is the Common Object Modeling (COM) standard. COM provides a methodology for defining software components in a way that hides the component implementation from users. The user is only required to know the interface defined, the way to communicate to the object, not the specifics of how the component does its job. There is a direct correlation between the need to communicate with instrumentation without knowing specifics of the instrumentation and the need to utilize components without knowing how they perform their functions. This proposal defines an approach to achieving complete test system instrument interchangeability through a robust, comprehensive architectural definition and implementation, using modern software technologies and paradigms. The results of this project will provide an element for use in test systems architectures that allows test programs to be independent of the test system they run on. When test systems or their resource components become obsolete the test programs will not require alteration when rehosted or when specific instruments are upgraded or replaced due to obsolescence. Additionally, if systems having multiple resources capable of the same functionality are present within a test system, then the RAI provided by this project will allow a test program to access any resource capable of performing the desired function. This ability to select any resource capable of performing the job makes a test system more adaptable and resilient in the face of resource failures or obsolescence. When many like instruments are present, as might be the case in a test system with virtual instruments, the capability to select any instrument that can perform the function is a highly desirable attribute. The DoD search for an acceptable RAI has been primarily driven by the need to reduce life cycle cost. This program will provide life cycle cost savings in the form of increased station up time, a longer operational life, and reduced test program rehost cost when a test system becomes fully or partially unsupportable. The capability is also expected to provide a means of easily simulating test systems when actual hardware is not available. This simulation capability will provide a means of performing off-line test program development without the need for test systems time during some development phases of test programs. This simulation capability could evolve into closed loop software simulation of the entire test scenario and could be used to validate test programs reducing station integration time needed. Beyond the department of defense, the commercial environment is also in need of the capabilities this program will provide. Full commercial acceptance of the products from this proposal is expected. Commercial acceptance will bring even more costs savings as the economies driven by market influences are achieved.

Title:High Power Compact Yb Waveguide Laser
Abstract:Laser sources for applications in directed energy, IRCM, and remote sensing on airborne platforms require exceptionally efficient operation, low mass, and compact size. Traditional laser designs do not meet the required efficiency and size goals, which has restricted the incorporation of lasers in many platforms, such as small FLIR targeting turrets. Furthermore, existing systems are prohibitively complex and expensive to be simultaneously successful in the industrial commercial markets. CTI proposes a new Yb-doped waveguide laser design that is (1) capable of producing a TEM00 beam, (2) can be scaled to high average powers (> 1 kW!), (3) is exceptionally compact, (4) has high efficiency, (5) has excellent thermal properties, and (6) can be pumped by multiple laser diode arrays with high coupling efficiency using simple cylindrical optics. The waveguide design is simple, yet operates on a completely different principle than planar waveguides or bulk lasers. The proposed Yb-waveguide architecture will find wide commercial applicability in the high power laser market, especially in materials processing. CTI's experience in flight-worthy laser systems helps ensure a successful Phase I/II program. Anticipated applications include (1) ultra-compact laser transmitters for a variety of military airborne platforms, (2) efficient and low-maintenance lasers for industrial materials processing, (3) high performance transmitters for laser remote sensing.

Title:An Yb-based Laser Transmitter
Abstract:For laser rangefinders and target designators, lightweight, compact, efficient, high-energy-per-pulse laser sources are desirable. Diode-pumped solid-state lasers are the best candidates for this application. A logical means of increasing the performance of current diode-pumped solid-state lasers is to increase their energy storage by exploiting materials with long upper-state lifetimes. Ytterbium-doped media offer lifetimes that are on the order of milliseconds, and are a factor of five larger than Nd-doped media. In the proposed effort, we will explore the use of Yb-doped laser media in an efficient prism-pumping geometry. The prism-pumping geometry provides a simple and efficient means of both side-pumping and removing the heat from a laser rod. The prism-pumping geometry has demonstrated very efficient operation as compared with currently used pump-cavity designs. An advantage of the prism-pumping geometry is that the laser medium is conductively cooled, eliminating the requirement for liquids flowing over the pump surfaces of the rod. The prism-pumping geometry, together with Yb-doped laser media, offer the potential of small, compact lasers with robust coupling of the pump diode lasers to the laser medium. Our short-term commercial market focus for high-energy-per-pulse Yb lasers is in the precision materials processing industries including applications such as: precision cutting and drilling on metallic and ceramic substrates, marking of wafers and components, post processing of components such as LCD displays, solar-cell scribing, drilling of holes and vias in high-density electronics substrates, and the stereolithographic production of mechanical models.

Title:Processor Technology Insertion Recertification
Abstract:EDAptive Computing, Inc. (EDAptive), Dr. Perry Alexander of the University of Kansas and Ball aerospace & Technologies Corporation (BATC) present a unique and commercially viable solution to the problem of characterizing Application Program Interface (API) for a real-time computing system and optimally testing characterized API upon processor upgrades. Our Characterize API for Real-time computing systems and Test upon processor upgrades (CART) program will apply an emerging formal specification language standard, and an innovative design verification test generation tool to the problem of processor technology insertion recertification. Specifically, we propose to research and develop a solution, which will employ two key emerging and innovative 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 API, and (2) the Air Force (AF) and Navy-sponsored Design Verification Test Generation (DVTG) tool to validate Rosetta specified API as well as recertify the API upon processor upgrade. We have discussed our approach with potential customers and partners such as BATC and BATC has indicated its willingness to support requirements definition and definition of a potential test case for our Phase I effort, if awarded. Maturation and integration of tools and languages proposed under this effort will alleviate the processor technology upgrade recertification 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 commercial software developers of real-time computing systems such as embedded systems to identify potential problems when upgrading processor technologies for obsolescence or performance needs.

Title:Processor Technology Insertion Recertification
Abstract:There is an emerging direction in systems development where plug-compatible reusable COTS components are utilized to keep systems affordable. However, a market of reusable processor technology components makes sense only if we certify these components and the overlaying baseline API to ensure that the substitutions, refinements, and compositions at the level of joint technical architecture (middleware) are safe, reliable, and downward compatible. Furthermore, techniques for assessing the satisfiability of distributed real-time QOS requirements of fielded joint systems and operational architecture elements are essential. We propose a multi-level recertification methodology and tool infrastructure that utilizes real-time ORB, called TAO, as a testbed API to reason, analyze, and test for the dependable upgradability of real-time systems. The methodology incorporates three levels: (1) an interface-level, model-based verification method for the substitutability and mutual compatibility analysis of the new component with respect to the characterized baseline API, (2) an automated API robustness testing method and infrastructure for testing the reliability and dependability of the API after the substitution, and (3) application protocol conformance and real-time QOS certification. A COTS level impact containment method that is based on a COTS level annotation and dependency modeling approach is also proposed to reduce the overall recertification space. The systematic analysis for dependable upgradability as well as the dramatic reduction of recertification efforts are the immediate benefits of the proposed method. Modular reasoning and certification at the API level along with an automated robustness testing method could lead to substantial reduction in maintenance costs, improvement in software reuse, and an increase in the quality of software.

Title:Silicon Carbide Coated Carbon Fiber Towlines
Abstract:This Phase I SBIR program deals with development of small-diameter towlines capable of withstanding loads of 500 lbs, temperature variations of up to 2000 oF and extreme environmental abuse in airborne and shipboard military and commercial applications. Silicon carbide coated carbon fibers are proposed as material capable to meet the proposed requirements due to the excellent mechanical properties of carbon fibers and good oxidation and corrosion protection in harsh environmental conditions provided by silicon carbide thin protective layer. Protective layer thickness, SiC crystallite size and coating surface texture will be optimized to maximize compatibility in mechanical behavior of two components of the coated fiber and to maximize flexibility of the towline without compromising its mechanical properties. It is expected, due to excellent mechanical properties ( load of 500+ lb with diameter of less than 0.1ý), small weight (density of about 2.00 g/cm3) and resistance to high temperature variations and to corrosive, harsh environmental abuses, that silicon carbide coated carbon fiber towlines could easily find applications in both air-space and marine environments for load towing, instrumentation sonds, probes and weather balloon tethering, as well as for a variety of construction applications where miniature, light-weight and high-strength cables are needed.

Title:Innovative Materials Solutions for IDECM High Temperature Tow Line
Abstract:Triton Systems, Inc. proposes to develop unique high temperature Towbody Towlines to be used for the Integrated Defense Electronic Counter Measure (IDECM) Tow Body Decoy systems. The Towline will be designed to withstand the extreme environmental conditions in airborne and shipboard military and commercial applications, and will be suitable for use in the entire operating envelope of the host platforms. The current state of the art material for use in Towline systems is an organic polymeric fiber that does not meet the extreme operational performance requirements. Triton's innovative solution will integrate 2 high performance material systems and thus provide an integrated system design that will be robust enough to withstand the extreme operating environment of the Towline. The first component will be a flexible high temperature resin that can be extruded onto the current Towline to act as an ablative heat sink. The second component is a high temperature fiber braid that is used as a thermal barrier jacket with low heat flux. Both components can be integrated into the current Towline system. Triton will be working with the prime contractor (Sanders - Lockheed Martin) and supplier (Cortland Cable Company) of the Towline to integrate Triton's material solutions into the current IDECM systems. Triton's proposed High Temperature Towline for IDECM Decoy Systems will enable cross platform implementation of current Towbody Towline designs. The ability to integrate Triton's innovation into the current Towline systems will allow for rapid qualification and deployment into the field. Triton is currently working with the system integrator and the sub-component suppliers to rapidly advance this technology to the field. The current market potential for towed decoy systems is approximately 30,000 units per year. Expanding the operating envelope of the towline to meet more extreme environmental conditions will expand the use of this system across new platforms. With this expanded mission platform, the market potential could extend beyond the military use. Other commercial applications could be to study geothermal activity on Earth or other terrestrial bodies.

Title:TOWDP - Thermal/Optical Wake Detection Processor
Abstract:As a sensing modality for wake detection, synthetic aperture radar (SAR) has received particular attention. However, SAR coverage is not sufficiently available from either spaceborne or airborne platforms, nor can it be operated under silent (passive-only) surveillance scenarios. These factors suggest that there remains a high payoff from employing airborne passive optical (visible, thermal infrared) sensing for ship wake detection. The challenge in achieving this payoff is cognitive exhaustion of the human operator, in addition to maintaining the high (and costly) levels of proficiency. Automated cueing offers a means to meet this challenge. Unfortunately, this cannot simply be achieved by applying existing SAR wake detection algorithms to optical imagery, due to the differing signature generation mechanisms. We propose TOWDP (Thermal/Optical Wake Detection Processor), with Phase 1 to demonstrate the technical feasibility of automating wake detection, concentrating on FLIR (forward-looking infrared) imagery. Our Option effort will establish cost feasibility of COTS PC-based TOWDP hardware implementation and P3 FLIR interfacing within a Phase 2 effort. A Phase 2 effort will implement and field demonstrate a flight-worthy prototype TOWDP onboard a Navy P-3 or similar testbed aircraft. Our technical team at Aerodyne Research is uniquely qualified to undertake this effort. Remote detection of ship wakes offers numerous and obvious military, border enforcement, anti-piracy, and search&rescue payoffs. An automatic wake detection processor would have several payoffs: (1) more flexibility in crew scheduling, as lower-skilled crewmembers would be qualified; (2) lower training and proficiency maintenance costs; (3) increased surveillance effectiveness.

Title:Automatic Wake Detection Algorithms
Abstract:Dynamics Technology, Inc. (DTI) will demonstrate the feasibility of automatic wake detection algorithms for Kelvin wakes and turbulent wakes and will identify other potential signature components. The algorithms will be based on generalized likelihood ratio detectors, which are known to be optimal when signal and noise statistics are known. DTI has previously demonstrated a computationally efficient version of a likelihood ratio detector for wake detection. Signal and noise statistics needed to design the detector will be calculated from DTI's existing wake signal and ocean clutter models, developed during 20 years of Navy ship wake research. These models will be benchmarked against the provided data. DTI will also develop decision aids to help the operator further reduce false alarms. Candidate targets will be derived from the automated wide area search algorithms described above, and the decision aids will be presented as imagery with signal enhanced and clutter suppressed. Automatic wake detection algorithms will reduce operator work load and improve operational capability. The algorithms represent a cost-effective method to enhance current ASuW and ASW sensors already in the fleet.

Title:Situation Assessment-Based Video Enhancement Agent
Abstract:The ability to autonomously enhance low-quality or corrupted streaming video data is essential in a number of important defense and civilian scenarios. In military applications, the need to enhance and clean-up corrupted video signal is crucial for operator-assisted or autonomous terminal guidance of missiles. Quality of video also affects critical decision-making in civilian applications ranging from security to remotely-controlled surgical procedures. The entertainment sector also demands high-quality imaging despite low-quality cameras (e.g. web-cam) and under adverse lighting conditions. In spite of the apparent need for video enhancement techniques, progress has been limited to either human-assisted video clean-up or to very specific types of automatic video correction (e.g. contrast enhancement). We propose to design and develop an autonomous situation assessment-based video enhancement agent. This agent will control the selection of specific video enhancement algorithm sequences and their parameters based on image stream and contextual information. The pool of image enhancement operators will include both frequency and spatial domain techniques, while image-based control information will be derived via localized feature extraction. The prototype suite of software algorithms and the autonomous control agent will run on a commercial, off-the-shelf embedded platform with a dedicated vision processor. Government and commercial applications that rely on the quality of video streams range from police work and surveillance to the medical and entertainment field. In all of these applications autonomous image enhancement would have an immediate and measurable impact on the successful task completion or quality of data presentation. Hence, the proposed software/hardware architecture has direct commercial potential in these markets.

Title:Real-Time Automatic Enhancement of Corrupted Video
Abstract:For this SBIR, PSI proposes an innovative application of data compression technology for video forecasting. We called this a Corrected Corrupted Video Viewer (C2V2). Using wavelet, and other compression transformations as a basis, we propose fabricating a software method to predict the next several frames of video as a type of Augmented Reality (AR). The original video will be accessible to the operator at all times. Further, using a less than real time sampling rate, the forecast video will be corrected, or calibrated, with the corrupted video at a sufficient rate to assure that the prediction is highly accurate. This prediction will be run in real time with the level of resolution desired by the operator/analyst, including introduction of transformation for functions at a higher resolution than available from the raw video. These higher resolution features can be introduced to the video stream from a previously stored library of features of interest. In Phase I we will demonstrate that the forecast methodology can be used to enhance real-time corrupted video. In Phase II we will implement an engineering prototype to test and demonstrate application of the technology to various video types and using various transformation algorithms. This will be done with a view that the final form, in Phase III, will be a video processor card with attendant software. The attendant software will provide for the transformation algorithm or algorithms, the forecast correction function, and operator software to initialize and operate the C2V2 and view the enhanced results. A significant issue in the implementation of software in the current business environment is the life-time of the system. Often, systems, even commercial systems, are virtually obsolete before they are even fielded. We are addressing one of the biggest problems in this are with our software architecture. In addition to developing the product in an "open System" environment for COTS hardware, we have proposed using a "drop-in, drop-out" implementation method for the transformation method. This would allow these methods to be upgraded, replaced, and used without significant change to the rest of the C2V2. It would be possible, under this design, for the individual user to tailor or develop their own specific transformation method, particular to their video needs, and insert it into the C2V2 for operation.

Title:Real-Time Automatic Enhancement of Corrupted Video
Abstract:Commercial and military communication systems are faced with the need to perform critical tasks based on the use of transmitted (or hard-lined) video. Military examples include the use of video to perform stand-off targeting, autonomous target recognition (ATR), and operator-assisted terminal guidance of a missile. For example, in the SLAM-ER when the infrared seeker is activated, it sends a video image to the pilot who selects a specific aimpoint on the target. The pilot then locks on to the target, and the missile makes an autonomous precision strike. However, due to the effects of turbulence, multipath, rain, low signal-to-noise, restricted bandwidth, electromagnetic interference, countermeasures, and/or other degrading phenomena this video is corrupted. Thus, the quality of the video becomes important and real-time autonomous corrections becomes necessary. Any improvement to the video will make it easier to place the seeker crosshairs on the target aimpoint. The objective of this project (Phases I and II) is to design and demonstrate real-time automatic video enhancement and image restoration techniques that substantially mitigate the corrupting effects for SLAM-ER IR video. The proposal team is composed of Scientific Systems Company Inc (SSCI) and the Advanced Video Systems group at the Sarnoff Corporation. Also, in order to effectively transition these efforts to the SLAM-ER platform, we are developing a relationship with the SLAM-ER group at The Boeing Company in St. Charles, MO. The development of the above core technologies in video enhancement and image restoration will serve as a foundation for Phase III commercialization. Commercial application of this technology exist in several areas such as: medical screening and diagnosis, remote sensing, road and bridge inspection, and buried waste detection.

Title:Avionic Schematics on Demand
Abstract:The Navy's avionic maintenance and training environment relies on computer based viewing of schematics and associated technical data. Current authoring and maintenance of schematic drawings in this environment requires collaboration between the system/design engineers, technicians and technical illustrators and is essentially a manual, labor intensive effort that is often late, not synchronized and contains errors. LSA proposes a systematic process for converting a CAD system generated component and pin-out, text file database into a graphical database, suitable for automatically generating schematics. The process utilizes the best aspects of the human input, such as usefulness determination, with the best uses of a computer system (i.e. accuracy, timeliness and consistency). The process will make use of application of a set of interactive filters, developed with the aid of the C Language Integrated Production System (CLIPS) Expert System development tool, to a text file consisting of a CAD system generated list of components, interconnects, and other essential information. The end product will be a database that can be used to automatically render a computer displayable, graphical representation of the system to include the capability to navigate through multiple electronic pages along specific interconnects. This innovation will have wide use in schematic environments to include general aviation, heavy machinery, utilities, the process industry and other industries where owner/operators use schematics for maintenance and training. It would also be useful for field service representatives and could be extended to provide mechanical and wiring drawings.

Title:Avionic Schematics on Demand
Abstract:The graphical information required to support a complex aircraft involves tens of thousands of graphics and hundreds of thousands of pieces of amplifying information from manufacturers, suppliers, and integrators. Such massive amounts of graphical and textual information requires a sophisticated capability to automatically convert, interpret, and integrate electronic data into information industry standard formats to facilitate the conduct of troubleshooting, repairing, and training activities. Troubleshooting charts, diagrams, component index tables, parts illustrations, standards tables, structural and tooling drawings, and schematics constitute such information. Schematic information is difficult and time consuming to utilize in contemporary forms. Schematic information or graphical knowledge needs to be automatically acquired to enable locating, recognizing and cataloging schematic symbols, components, text, and connectivity. Once acquired this graphical knowledge will enable the development of algorithms for viewing, searching, and tracing connections among graphic objects between schematics. A software tool set and associated databases of components and interconnections among components will be enabled and rapidly deployed through established customer bases in several industries using CAD, CAM, data synchronization, fully backend supported internet based applications for facilities management, process industry maintenance, and vehicle depot and field maintenance. van Houten's business partner will support commercialization of this technology. The product concept is to provide customers with a fully integrated schematic management process supported by LAN, WAN, and internet ASP software allowing for the creation, warehousing, and synchronization of smart schematics deployable to the point of application for training, maintenance and decisions making. This will fulfill the customer's needs to improve the productivity and quality of all work tasks supported by the schematic management process. This product concept has been validated for the aviation, automotive, chemical process, utilities (telephone, electrical power, and water supply), and cable television industries.

Title:Multiple Small `Smart' Weapons Carriage
Abstract:Desert Storm gave impetus to a new class of smaller, smarter low cost weapons, with a reduced logistics footprint, which are effective in all weather conditions. Air Force Research Laboratory (AFRL) has demonstrated such munitions. However, the focus of aircraft integration has been internal carriage on the F-22 and Air Force JSF. Navy and Marine Corps requirements have yet to be considered. This program will investigate addressing Navy and Marine Corps needs in this area. The significant research efforts include (1) evaluating non-pyrotechnic ejection force generators for bomb racks and (2) performing fluid dynamic analysis of concepts for ejecting relatively small stores out of aircraft weapon bays through the shear boundary layer. The desired systems will allow for the carriage of multiple (minimum of four) small `smart' weapons on one MIL-STD-1760 Aircraft Station Interface (ASI). Weapons will be independently targetable and individually releasable. Suitability for storage and maintenance at sea will be a major factor in design and development. Cost per kill and total cost of ownership will be critical metrics for system evaluation. Novel and innovative low cost design, manufacturing, and supportability concepts will be explored. A Life Cycle Cost (LCC) model will be developed to assess design alternatives.

Title:A Seeker Processor Simulating the Columnar Organization of Cortex Areas of Brain
Abstract:CST Corporation proposes a novel approach to an integrated signal-processing system for terminal guidance seeker by simulating the columnar organization of mammal's cortex areas of sensory processing. The columnar organization of mammal's cortex exhibits a very efficient way of using the computing and communication resources and an ideal matching of the physical organization with versatile signal/image processes, particularly the adaptive and robust vision processes for target acquisition, tracking, and pointing. The phase I work will develop processor architecture suitable for the imaging sensor based terminal guidance seeker. The functional requirements, the physical constraints, and the technology availability for the terminal guidance seeker of missile will be studied through literature review, computer experiments on key processes, and analysis. Important results from CST's previous work on imager based target detection and tracking will be incorporated into this R&D. Besides this application, the integrated signal-processor is also useful for industrial automation, manufacturing, robot vision and position location, UAV based survey systems and material delivery systems.

Title:High-Speed Image-Recognition Control System
Abstract:Terminal guidance of weapons immediately prior to impact is an especially demanding control problem. While Global Positioning System (GPS) guidance can get a weapon close to a target, a greater level of accuracy is often needed to account for uncontrollable factors such as the movement of a target. QEI Technologies proposes to develop an entirely new class of pattern recognition control system that is exceptionally fast, inexpensive, and rugged. This control system is based on a novel mathematical methodology that eliminates many faults or limits found in existing control architectures. Phase I work will focus on demonstrating the new control system through mathematical modeling. Models will include the connection of a digital imaging sensor to the control system, and simulated target patterns will be input to the control system through the simulated imaging sensor. A preliminary electronic circuit and bill of materials for hardware implementation will be completed by the end of Phase I. Phase II work would focus on the hardware demonstration of the control system and validation of Phase I modeling results. Phase III will see the production of monolithic imaging and control integrated circuits implementing this new control methodology. Successful completion of this project will result in a new class of control system that will have a wide range of military and commercial applications. The control system will significantly improve the accuracy of GPS/INS guided missiles. In addition, the fast, low-cost system will be applicable to vision systems used in many applications such as surveillance, autonomous vehicle control, and manufacturing control.

Title:Integrated Missile Seeker Signal-Processor Development and Implementation
Abstract:The Navy needs an autonomous target recognizer capability for integration with INS and GPS for missile applications. The proposed integrated system consisting of a Fast Pattern Recognizer, INS, and GPS is referred to as the FIG. Using a Kalman filter, the integrated FIG can improve the accuracy of INS/GPS navigation system errors and correct aimpoint errors in terminal areas caused by target location errors. The FPR enhances the INS/GPS navigation by autonomously detecting, identifying, correlating, and tracking complex targets in hostile, high-clutter environments in real time. Since image correlation is computationally intensive, real-time processing must be accomplished by means other than available traditional hardware and/or software. The proposed FPR system easily accomplishes this task with rated processing speeds equivalent to 150-1 GHz MHz Pentium III PC's. During Phase III, this speed can be increased an order of magnitude to the equivalent of 1500-1 GHz Pentium III PC's by implementing the FPR as an application specific integrated circuit (ASIC) chip-set in a multi-chip module (MCM) that is less than two inches square. The latter version offers additional benefits in reduced power, size, weight, and cost while increasing circuit density, processing power, and throughput rates for virtually all image-processing applications. Real-time autonomous target recognition needs exist in commercial applications for image correlation, identification, and recognition for law enforcement, medical, security, product assurance, and non-destructive testing. The commercial applications represent a market for more than one million FPR units.

Title:Rapid Transition of Synthetic Aperture Sonar Technology for Fleet MCM and ASW
Abstract:Dynamics Technology, Inc. proposes to explore an opportunity to transition rapidly to the Fleet a new set of capabilities with only minimal development, hardware or acquisition costs. We will assess the feasibility of applying synthetic aperture sonar in a new way to both mine warfare and antisubmarine warfare (ASW) by the use of existing mid-frequency (~3kHz) active sonar transmitters on current ships and submarines and the use of towed array transmitters that can be manufactured under an existing contract. If successful, this approach will deliver to the Navy a new capability to perform acoustic submarine and mine search at unprecedented ranges and area coverage rates with systems organic to current warships. We project tactical active ASW coverage rates as high as 500 square nautical miles per hour and a mine detection-through-identification capability at many kilometer ranges with the potential of 100 square nautical miles per hour coverage using the same system both for ASW and MCM. Commercial benefits will also accrue in the areas of bottom search and ocean survey.

Title:Rapid Surveying of Buried Mines by Conjunct Seafloor Image and Biomimetic Signal Classification
Abstract:Cost- and time-effective mine countermeasures (MCM) are of great interest to the Navy. The ability to rapidly sweep wide areas and provide accurate threat detection and classification is critical to an effective MCM system. Current biologically based systems perform extremely accurate classification, but require extensive operator/trainer interaction. The goal of this Phase I SBIR effort is to develop an adaptive acoustic (AA) mine-hunting system comprised of a high-resolution wide-area search transducer coupled with advanced real-time image processing and biomimetic classification algorithms. Preliminary work has shown both the feasibility and potential of this approach. The goal of this Phase I effort is to build an integrated sonar system capable of automatically detecting and classifying buried targets using complementary sonar spatial imagery and acoustic time series signal processing. The planned Phase I effort includes development of algorithms for image processing and acoustic biomimetic target classification, collection of acoustic survey data of buried targets, and development of a processing engine capable of fusing the imagery and acoustic processing chains to reduce false alarms. Phase II tasks include continued data collection for performance evaluations, algorithm enhancement, and development of a real-time hardware implementation of the system. The project will culminate in an at-sea test. The technologies described in this proposal have utility in a wide range of commercial applications, including beach and shoreline analysis; planning and design of coastal facilities such as harbors, marinas, breakwaters, and ocean sewage outfalls; location of undersea pipelines and cables; underwater environmental monitoring; and remediation of offshore areas of military test ranges for public access.

Title:Laser Scalar Gradiometer for MCM
Abstract:This Phase I Small Business Innovation Research Project will develop a conceptual design for a Laser Scalar Gradiometer (LSG) deployed on a MCM Unmanned Underwater Vehicle (UUV). The LSG will be used to locate buried mines and eliminate false targets in shallow-water MCM operations where conventional MCM systems are degraded and it is desirable to eliminate the risk and logistical demands of marine mammal assets and operators. Polatomic laser magnetometer technology was recently demonstrated in the POLATOMIC 2000 (P-2000) ELF Laser Magnetometer for airborne ASW ELF detection. The P-2000 can be operated in a gradiometer mode and demonstrated sensitivity of 0.2 pT/ft for sensor separation of one foot. The LSG design goal is high sensitivity, omni-directional measurements in the mine detection frequency band. In Phase I, performance data will be collected using a P-2000 in gradiometer mode. A LSG conceptual design based on P-2000 magnetometer technology will be developed for optimized mine detection performance. The LSG conceptual design will address miniaturization and packaging for deployment in an autonomous UUV with low-frequency sonar. The feasibility of designing and fabricating an LSG prototype in Phase II will be assessed in Phase I, and the Phase II technical plan will be developed. The Laser Scalar Gradiometer will provide state-of-the-art, room temperature detection systems used for ASW, locating magnetic mines and unexploded ordnance, ELF receivers, earth and planetary magnetic surveys, as well as vehicle and intrusion detection.

Title:MCM Technologies for Detection, Classification, and Identification/Localization of Sea Mines and Submarines
Abstract:As the Gulf War demonstrated, undersea mines will be a major threat to U.S. Naval forces during regional conflict in littoral waters, especially those involving countries without sufficient air or naval forces to pose a threat to U.S. warships. Acoustic systems designed to find bottom mines must not only detect objects with very small target strength against a reverberant background, they must provide extremely high resolution in order to discriminate between mines and mine-like objects on the bottom. Even with high-resolution sonars, observation of an object from multiple look angles is sometimes needed to successfully classify as non-mine or mine. Classification therefore limits the search rate of such sonars, both because high operating frequencies are needed to obtain high resolution in angle and because achieving multiple look angles slows the rate of advance. This proposal will investigate use of multistatics to improve mine detection and extend ranges at which classification is possible. Practical system configurations for a multistatic acoustic mine detection sonar will be developed and estimates of detection range, localization accuracy and classification range will be developed for these configurations. Search rate will be determined as a measure of effectiveness for comparison with conventional monostatic MCM sonars. The acoustic sensor developments anticipated under the proposed project will improve the detection of small objects on the sea floor. Further, by providing improved resolution with lower frequency sonars, these developments are anticipated to improve the range at which such objects can be classified. The primary candidate markets for this effort are anticipated to be the US Navy's mine avoidance and MCM programs. However, resolving objects multistatically can support improved classification in tactical ASW sonars as well. Other potential civilian markets include any application requiring imaging of the ocean floor such as shipwreck location, downed aircraft search and locating pipeline or cable routes.

Title:Maritime Intelligence, Surveillance, Reconnaissance (ISR) and Space Exploitation
Abstract:Daniel H. Wagner Associates, Inc., with Science Applications International Corporation (SAIC) as a subcontractor, will develop a report containing requirements and a detailed design for a Level 2 data fusion system that will significantly improve mine warfare situational awareness within the maritime littoral region. As defined by the Joint Directors of Laboratories Data Fusion Subpanel, Level 2 data fusion (situation assessment) involves creating hypothetical scenarios of the state of the threat, including patterns, placement, and types of mines. This Mine Warfare Situational Awareness (MIWSA) system will evaluate the mine warfare situation using information from MIW Intelligence Surveillance and Reconnaissance (ISR) operations. It will also determine how best to utilize available MIW Intelligence Surveillance and Reconnaissance (ISR) assets to improve the situational awareness of MIW planners and operators. MIWSA will allow MIW planners and operators to (1) develop more effective ISR plans, (2) more accurately evaluate the effectiveness of ISR operations, and (3) more accurately evaluate the threat to shipping from mines that may be in a maritime littoral region of interest. Having these capabilities will significantly improve the ability of Naval MIW forces to carry out their missions through the more effective use of information obtained from ISR systems. The immediate benefit to the Government at the end of Phase II will be a full scale prototype system that uses Level 2 data fusion techniques to evaluate and optimize MIW ISR operations. Improved MIW technologies such as these are particularly necessary at a time when the United States is facing a sophisticated MIW threat with limited funds to procure additional MIW assets/sensors. Effective use of Level 2 data fusion techniques in MIW operations will produce more effective MIW operations, conducted at lower risk, which will result in fewer casualties to friendly forces and improved overall US Navy effectiveness.

Title:Multisource Maritime Surveillance
Abstract:End-to-end targeting systems for littoral warfighting require effective decision support from maritime intelligence, surveillance, and reconnaissance (ISR) assets. Novel data fusion engines can effectively correlate, fuse, and track contacts and targets of interest, offering high-payoff, automated subsurface and surface ISR. Our proposed approach for Multisource Maritime Surveillance will leverage ORINCON-developed technology to fuse information from multiple diverse sources, including, but not limited to, passive and active acoustic, airborne/spaceborne imagery, and airborne video imagery. ORINCON has developed and currently uses state-of-the-art multiple-hypothesis tracking (MHT) algorithms to fuse passive and active acoustic information into a common scene. In conjunction with Prof. R. Chris Olsen of the Naval Postgraduate School, we will begin investigations into the fusion of airborne/spaceborne visible and infrared imagery into the acoustic view of the littoral region. This work will begin an effort in which data from all available sources is fused into a common picture to provide the Fleet with improved understanding of the littoral region as the Navy moves into the 21st century. Commercialization begins with technology insertions for Northrop Grumman's Tactical Exploitation Surveillance System and Littoral Surveillance System (TESS/LSS). ORINCON's data fusion and automation technologies directly apply to ONR's Deployable Advanced Distributed System (DADS) and can be seamlessly integrated with future fielded systems such as the Advanced Deployable System (ADS). Vessel traffic managers and regional airport traffic controllers will also benefit from our hybrid data fusion engine that handles both image-processed and signal-processed inputs. The fusion of imagery data with Joint STARS moving target indicator (MTI) radar has potential applications in other branches of the military. Anticipated benefits extend to commercial markets for our pattern recognition, data correlation/fusion, and knowledge management products for health care industries and multiple electronic businesses.

Title:Remote Monitoring of Ships via Infrared Multispectral Imagery
Abstract:This proposal explores the utility of space-based thermal infrared (TIR) multispectral imagery (MSI) for detecting, monitoring and identifying ships in the littoral zone. MSI provides a remote, passive, and day/night capabilities, it can penetrate fog and haze, and it can detect subtle ship thermal signatures. Currently, ambiguities in separating temperature, material emissivity and atmospheric effects complicate the remote detection and identification of ships. To address this problem we propose developing new TIR atmospheric and sea surface properties retrieval and ship detection/identification algorithms, dubbed MASTS (Multispectral Algorithms for Ship Thermal Signatures). MASTS uses physics-based radiative-transport algorithms plus a representative library of ship parameters to enhance the information content of TIR images. It retrieves the upwelling ship surface radiance and gleans additional information about the target, including its shape, surface temperatures, and materials In Phase I, we will develop the basic MASTS algorithms and demonstrate their effectiveness using real littoral zone MSI data from the recently launched DOE Multispectral Thermal Imaging (MTI) satellite. In Phase II the algorithms will be refined, integrated into an analyst driven software package, and applied to analysis of additional data from MTI and from an airborne hyperspectral imager. The anticipated result is a software package, the MASTS tool kit, that incorporates new algorithms for retrieving ship temperatures and material emissivities, and performing ship detection/identification using aircraft and satellite-based TIR MSI data. MASTS will be applicable to TIR MSI sensor design applications in the Navy and other US Government agencies, and analysis of real data to be acquired from present and planned sensor systems. Other Government applications include surveillance in the littoral zone and open ocean, target detection and identification, technical intelligence. Commercial applications include littoral traffic monitoring/control, civilian law enforcement/surveillance, crop health monitoring, and mineral/natural resource detection.

Title:An Air Deployed Multi-cycle Ocean Profiler for Intelligence, Surveillance, and Reconnaissance
Abstract:A new tool for Navy intelligence, surveillance, and reconnaissance is proposed. A profiler, in an A size sonobuoy configuration, able to make 100 plus profiles with an endurance of 60 days, capable of supporting a wide-range of physical and acoustic sensors, GPS positioning, line-of-sight, or global satellite communications and under water coustic modems. The profiler proposed is a logical extrapolation of the ALACE civil research profiler. The development is of low to moderate risk and has a rich field of future development, particularly in adapting the variable buoyancy to create gliding vehicles capable of controlled vertical and horizontal movement. The Phase 1 component proposed is to construct three prototypes and demonstrate them in the field. The prototypes will be of A size Sonobuoy physical envelope, for hand development with the data collected, processed, and distributed by Internet. The technical background is outlined, including examples of field observations. The proposed profilers are expected to be a useful addition to the Navy tactical toolbox, useful in ocean data assimilation and environmental assessment as well as civil applicaitons. The air-deployed profilers may have a role in short-lived marine events, oil spills, rescues, major underwater seismic events, etc. A group of profilers can be air deployed quickly, programmed to sit on the bottom and ascent sequentially acting as surface drifters as well as profilers. There may be a role in ocean and climate research for a long-life version with accurate sensors for air deployment in remote areas, or from deployment from ships of opportunity to complement the worldwide deployment of 3000 civil research profilers planned in the international ARGO experiment.

Title:ISAM Nanoparticles/Polymer Thin Film for RF Transparent Appique
Abstract:This Small Business Innovation Research Phase I project will develop novel RF transparent, optically tailorable appliques. This will be accomplished by incorporating specific nanoparticles in thin films that can be deposited on any type of substrate, including transparent plastic sheets such as polystyrene. The technique of fabricating these films, called ionically self-assembled monolayer (ISAM) technique, allows for precise molecular level control over the assembly of a thin film with exceptional homogeneity and ease of processing. ISAM nonlinear optical films offer additional major advantages of excellent homogeneity for low scattering loss, high thermal and chemical stability, simplicity and low-cost. Luna Innovations and its university collaborators have shown that revolutionary ISAM methods of creating multifunctional thin-films monolayer by monolayer can be used to yield a wide variety of self-assembled, electronically and photonically-active polymeric thin films, including light emitting diodes, photovoltaic devices, and second order nonlinear optical monolayer films, to mention a few of the applications for the ISAM thin films. The ISAM technique uses only water soluble materials, eliminating the need of volatile organic compounds (VOCs) or any other toxic materials, is a low cost thin film fabrication technique. Besides the military applications of the ISAM RF transparent appliques, other fields, such as automotive industry, could benefit from these results. The new transparent sheets can reduce the heating in buildings and automobiles due to infrared absorption, thus reducing their cooling costs.

Title:RF Transparent, Optically Tailorable Appliqu‚
Abstract:Proliferation of infrared sensors in target acquisition systems and precision guided munition seekers has a major impact on survivability of aircraft, ships, and surface vehicles. Recent advances in materials and thin film technologies have produced effective IR signature control coatings that can be tailored for performance from the visible through all of the infrared threat bands while being compatible with underlying RF treatments. Sigma proposes to produce three different types of appliques to cover a variety of applications with particular focus on dielectric constant (RF transparency), and durability under extreme environmental conditions. All proposed applique systems will be configured to meet various conventional requirements, including weatherability, solvent resistance, color, and gloss. Phase I samples will be produced in large scale production equipment that will allow future scale-up for field test trials. IR signature reduction appliqu‚ systems will improve safety and reduce operation costs. Non DOD applications for such appliqu‚ technologies include commercial and private aircraft, automotive, thermal control, security, and various specialty coatings.

Title:Fully Integrated Micro Sensor IMU
Abstract:The success or failure of military operations increasingly depends on situation awareness. Critical to situation awareness is the knowledge of the precise position and heading of weaponry and personnel. There is a need for navigational systems independent of external sources and signals that would provide information about the position or movement of weaponry and personnel. Elsicon proposes a fully integrated Micro Sensor Inertial Measurement Unit (IMU) that can measure the linear acceleration and rotation of objects. The compact design makes the proposed Micro Sensor IMU rugged and robust for military applications. The integrated nature of the Micro Sensor IMU increases the potential for economical manufacturing. As a result, the Micro Sensor IMU has potential in commercial applications. The compact, integrated, economical nature of the proposed Micro Sensor IMU makes it ideal for commercial applications. These devices are compact enough to be carried by individuals or incorporated into any moving vehicle. As a result, applications abound in the areas of security and travel. The Micro Sensor IMU can be used in any navigation and guidance applications independent of the GPS system. However, the Micro Sensor is also synergistic with the GPS system and can increase the flexibility and reliability of navigation systems that use the GPS system.

Title:High-g MEMS Inertial Measurement Unit
Abstract:Tactical guidance and navigation grade inertial measurement units (IMU) are typically bulky and costly. Numerous MEMS-based efforts to develop low cost IMU's have not yet produced performance specs suitable for tactical grade classification in almost 10 years of research on the topic. However, recently developed deep reactive-ion-etching (RIE) based, single-crystalline-silicon micromachining methods appear to provide the possibility of meeting the difficult tactical grade classification. Among various deep RIE based methods, we propose to use the Surface/Bulk Micromachining (SBM) technology to develop IMU's capable of tactical grade classification. The SBM technology can fabricate single-crystalline-silicon gyroscopes and accelerometers on a single wafer. The SBM technology also allows a unique in-situ process step for correcting micromachining errors to match the actual IMU performance closely to the design specifications. A laboratory working micro gyroscope sample has already been fabricated using the SBM technology, and preliminary measurements are very near the target goal. Our proposed work will focus on developing optimized designs for tactical grade classification, including the harsh vibration, shock and temperature requirements. The market size for guidance and navigational grade IMUs is cost sensitive as with all markets. The IMU to be developed would lower systems cost by more than an order of magnitude and thus open up commercialization opportunities that to date have been only dreams. An IMU in this price category manufactured in volume would support a coupled GPS-IMU system of extreme accuracy for personal and business use in addition to military.

Title:Efficiency Improvements in Modular Ocean Wave Powered Generators
Abstract:The program proposed by OPT is a multi-pronged effort aimed at improving the energy conversion efficiency of ocean waves to electrical power by a factor of 5. It is about fundamental improvements in the physics and engineering of the conversion process and not about, e.g., building larger structures at lower manufacturing and deployment costs, which, although important, will come later when these improvements have been established. The goal of this program is to increase the power output of the basic OPT module from 20 kW to 100 kW. There are several key sub-systems involved in this improvement and these will be optimized and analyzed in detail in the program. 1. Wave Energy Capture Buoy: converts wave height into linear motion in the buoy. 2. Hydraulic Cylinder/Motor: Converts (very) slow linear motion to high speed rotary shaft motion. 3. Electrical Generator: Shaft common to hydraulic motor; produces electrical power output roughly proportional to the square of the shaft speed. The increased performance of these sub-systems will be the end result of the Phase I effort and lay the foundation for future work. The demand for energy is huge and universal. This R&D program will produce renewable (non-polluting) wave powered energy at 5 times lower cost than currently available. The significance of the opportunity is potentially enormous in both the commercial and military sectors. This is particularly true for remote areas such as islands in the Pacific where the cost of importing and storing diesel fuel is exorbitant (¯ 25c/kWh) and the wave climate is ideal. The local populace (which includes US Navy bases in many cases) benefits. In addition, the Navy has unique requirements for powering autonomous systems that, realistically, can not be done any other way.

Title:Modular 100 kW Wave Powered Electric Generator
Abstract:We propose a bold new way to generate electric power from ocean wave motion. Our approach stands in stark contrast to the indirect, bulky, expensive, and mechanically-inefficient methods now typical of this field, in which even the most successful methods are inherently shore-based, capital-intensive, or incompatible with rapid deployability. Yet in every case, the basic problem is the same: the ocean offers up its power as very strong forces (e.g., many tons) acting at very low velocities (e.g., 1 m/s). The use of a conventional electric generator demands application of inefficient mechanisms (e.g., air pressurization / turbine systems) to provide the necessary mechanical impedance-matching, i.e., to convert the wave power into a weaker force acting at a higher velocity. But SARA's scientists have discovered how to shift this impedance-matching burden from the mechanical to the electrical domain, via a cleverly-configured magnetohydrodynamic (MHD) generator. The low-impedance MHD output is converted to more practical voltages and currents via efficient electronic switches and compact transformers, rather than cumbersome mechanical contraptions. The result is both compact and highly deployable. In fact, this new approach may be the long-awaited technological breakthrough that will make ocean-wave energy competitive in a broad range of applications. The proposed technology has numerous commercial and military applications, with the nearest-term being provision of electric power at critical remote ocean and coastal locations. In contrast to existing ocean-wave power conversion alternatives, this new approach offers the promise of a highly-compact, rapidly deployable, highly-efficient, and low-cost solution.

Title:Rigid, Sectored-Cylinder, Composite-Sandwich Cofferdam
Abstract:Proposed for development is an escape trunk cofferdam that is made of a set of rigid (composite sandwich) cylindrical sectors joined by longitudinal sealing joints. The cofferdam is attached to the escape trunk's bubble skirt by an attachment ring which allows the sections of the cofferdam to be staged below the hatch before it is opened. When the hatch is opened, the sectors are raised through the hatch. Then activation of a set of pneumatic longitudnal and circumferential seals locks the cofferdam in place and makes it watertight. For passage of personnel, the composite cofferdam has an inner step and a folding step to reach outside the cofferdam. The proposed cofferdam is expected to be activated more quickly than an inflating-body cofferdam and will be far more suitable for the rugged and frequently sharp-edged environment of a submarine. The material to be used for the cofferdam is also significantly less flammable than materials used typically for inflatables. The project proposed includes the design of the sandwich shell, development of both mechanical and pneumatic type seals for comparison, and fabrication of a breadboard suitable for illustrating its fit and function dockside. The cofferdam proposed for development is based on existing commercial products and offers a low-cost path to a set of long-lived cofferdams for the Fleet. This cofferdam can be applied to a number of applications in the construction industry.

Title:Submarine Forward Escape Trunk Cofferdam
Abstract:A system concept is developed for the design of a stowable watertight enclosure for the submarine forward escape trunk hatch. Concept feasibility is assessed and work on a system prototype is initiated. The proposed enclosure is constructed of inflatable elastomer and can be processed via conventional techniques. It attaches to the hull and integrates with the lower ("bathtub") section. The enclosure has a raised rim above the hatch and can accommodate steps for easy personnel access. As a Phase I Option, we would continue work on a system prototype. The enclosure system will eliminate the disruption caused by large amounts of sea water coming down the hatch during personnel transfers at sea, and the sailor workload required to clean it up. As a result such transfers will be less disruptive and safer. Potential commercial applications include use of the enclosure system by foreign navies, research vessel submersibles and recreational industries conducting similar brief stops for personnel at sea.

Title:Liquid Fuel Atomizer
Abstract:Electrostatic fuel injector technology will provide the Navy a unique opportunity to maximize Pulse Detonation Engine (PDE) wave speed and thrust with minimum cost and complexity. Both SPRAY TRIODE and MEMS mockup (<.01 lbm/sec) electrostatic atomization technology, including benchtop PDPA atomization measurement, will be evaluated during Phase I. Charged Injection Corporation will team with CFD Research Corporation and the Navy Postgraduate School to perform an analytical comparison of electrostatic versus conventional PDE fuel injection. Work will focus on providing: 1) a multi-orificed design capable of flowing >0.5 lbm/sec at <50 psid, with an 8 micron SMD droplet plume and, 2) functional on-off pulsing operability up to 200 Hz with durability in excess of 600 seconds under nominal PDE operating conditions. Current power requirements to achieve this performance will be less than 10 watts with a total system weight and volume < four pounds and 54 (3x3x6) cubic inches. Phase II will focus on fabrication and demonstration of a flight configured prototype unit. Test and evaluation will include measurements of droplet size and distribution at all operating conditions while exceeding all operational specifications. One complete unit, with adequate spare parts, will be delivered to the Navy to support rigorous test and evaluation in an actual PDE test environment. By providing quantum enhancement of the fuel atomization and mixing processes, and reduction in fuel delivery pressure, the proposed electrostatic atomization technology can revolutionize PDE technology. The ultimate commercial potential of inserting this technology within the aerospace propulsion, power generation, and reciprocating engine industries exceeds the typical SBIR commercialization scale.

Title:Liquid Fuel Atomizer
Abstract:Pulse detonation engines (PDE) are a revolutionary approach to airbreathing propulsion and have the potential to increase range and thrust. Demonstrating rapid deflagration-to-detonation in a PDE combustor using storable, liquid hydrocarbon fuels is essential to their successful development. Unfortunately, liquid fuels require atomization, which introduces the challenge of detonating a liquid droplet spray. Recent research shows that droplet Sauter-mean diameters of less than 3 mm may be required. New atomization technologies will be required to produce these small droplets, as current liquid atomization techniques do not meet all Navy requirements (droplet size, high temperature operability, low pressure drop, high speed on-off pulsing with zero-drip closure and high flow rate). TDA Research, (TDA) teamed with the University of Colorado-Boulder, proposes a novel high-speed, addressable atomization technology to meet these requirements. Monodisperse droplets with a Sauter-mean diameter less than 10 mm will be produced at rates up to 100 kHz with very little pressure drop. The atomizer will be designed to operate with kerosene fuels in the high temperature and pressure environment characteristic of PDEs. Phase I experiments and detailed design of a liquid-fueled atomizer will lead to prototype construction and evaluation in Phase II. We anticipate that the atomizer developed by this research will be applicable in a wide range of propulsion and power generation applications including aircraft and stationary gas turbine engines, ramjets, and liquid fueled rockets. Modern high performance liquid-fueled combustors typically operate at very high energy densities requiring that the fuel be rapidly atomized, evaporated and mixed with the oxidizer. Special attention should also be paid to avoiding combustion instabilities that can impair performance and/or damage hardware. For stationary power generation applications, environmental concerns make prevaporized/premixed operation attractive, but it is again susceptible to combustion instability. The availability of inexpensive, robust injectors that can be modulated at high frequencies will open the door for practical active combustion control. In addition, diesel and gasoline direct injection are potential automotive applications with about the same operational frequency as the PDE. Lastly, agricultural markets exist for fertilizer and pesticide dispersion and cooling of livestock.

Title:Power Generation During Buoy Operations
Abstract:A low rate, very high energy metal-dissolved oxygen fuel cell is proposed as a power source for autonomous buoy operation. The goal is to provide continuous delivery of at least 35 watts power for at least 6 months (151.2 KWH). The energy density of the low rate system is estimated to be in excess of 500WH/Kg and 120WH/liter (including a DC-DC Converter). The Phase I effort will focus on the evaluation of several candidate metal anode constructions and metal/catalyzed metal oxygen reduction electrodes. A very low cost, seaworthy power source will find wide application in defense, scientific, and recreational applications where a safe, extremely high energy density power source is a requirement.

Title:Power Generation During Buoy Operations
Abstract:An inexpensive, rechargeable and reliable electrical power system for marine buoys is proposed. This unique, safe system decomposes seawater to make pure hydrogen to supply a fuel cell, which converts the hydrogen directly to electricity at 50%+ efficiency. The system is passive and insensitive to corrosion or shock. Hydrogen is produced by water reaction near ambient temperature with activated magnesium alloy. The only byproduct is Mg(OH)2 , milk of magnesia. The new Mg alloy has reaction properties with seawater that are ideal for a power source with varying electrical demand and on/off requirements. The fuel cell is a commercially available proton exchange membrane, hydrogen-air unit. The system needs no electronics or moving parts. It will produce about 1.3 kWh per kg of total system weight. Consumable reagents should cost less than $4/kWh. Periods between magnesium alloy recharging can be much longer than six months. During Phase 1 an integrated prototype system will be prepared to work continuously without maintenance. This effort will include optimizing the composition and geometry of the rechargeable magnesium alloy elements; designing an integrated system for buoy requirements (e.g., 35 W for 6 months) and conditions; and testing/optimizing of the selected prototype. It is anticipated that the NAVY will gain from this R&D effort an electrical power source which will have 1.4kWh energy capacity per kg of total weight . This unit can easily be adapted as a power source for marine buoy and produce 35W of electrical energy for 6 months without any maintenance service .This system is ideal for different low power marine applications.

Title:Electronic Warfare Adaptive Spatial/Spectral Cancellation
Abstract:Integrated Sensors Inc. proposes to develop and demonstrate techniques that effect practical, operationally meaningful, spatial and spectral nulls to mitigate interfering own-ship RF sources for high-resolution antennas used in shipboard electronic warfare systems as a way of maintaining high system performance within complex, dense RF tactical environments. A comprehensive Phase I and Phase II program is described with this goal in mind. Upon successful completion of the Phase I effort, ISI will have developed an architecture which will provide a practical spatial/spectral own-ship RFI cancellation approach. Computer simulations predicting performance against narrowband and wideband own-ship RFI will provide the primary validation mechanism. This effort will provide substantial evidence of feasibility by identifying techniques, requirements and system trades validating the approaches. Measures of performance and measures of effectiveness will be developed to provide a basis for performance comparison. Extension of existing simulations will provide validation and evidence of feasibility of the resultant spatial and spectral rejection techniques against own-ship emitters during the Phase I effort. The Phase II effort is designed to validate the Phase I design in laboratory and antenna range field tests using efficient signal processing techniques. The technology developed can become an integral part of many future EW and passive sensor designs for both military and commercial applications. A variety of applications for shipboard, airborne, spaceborne and ground based passive receive systems can significantly benefit. Commercial applications for communications systems will also benefit from this technology development.

Abstract:This proposal addresses the investigation of several methods to suppress RF interference from own-ship RF transmissions that can affect the performance of next generation shipboard EW analysis systems. The principal area needing cosite RFI mitigation is the direction finding portion of the EW system.

A program is proposed that will investigate alternative methods in order to select a preferred approach for subsequent implementation and testing in Phase II. Permit accurate direction finding of potentially hostile emitters in the presence of cosite, or remote interference in shipboard, terrestrial, or airborne EW systems.

Title:Molten Salt Incineration for the Disposal of Food Wastes
Abstract:When ships are at sea food waste can be disposed of by simply dumping it over the side. When they are in port the wastes must be either stored for later disposal or consigned to a commercial waste handler. Both of these options put limitations on the ships. The system proposed here will permit the ship to safely dispose of food waste in any location through closed incineration in a molten salt incinerator. An incinerator with a volume of 45 liters is sufficient to dispose of the waste produced by 400 sailors in a mess. A molten salt incinerator operates by rapidly heating the waste to a temperature between 700 and 1,000 øC in an oxidizing atmosphere through the use of a molten salt bath as a heat transfer agent. The waste is completely mineralized in seconds and the gases are ready to expel. Because the combustion is complete, the exhaust will meet air qual-ity standards in most areas. The development of the proposed molten salt incinerator will not only solve a growing problem for the U. S. Navy, it will offer an improved waste handling system for many of the 87,000 ships that ply the worlds navigable waters today. The same system that is proposed here for the Navy is suitable for use on cruise ships, permitting them to rapidly and efficiently dispose of food waste, even in environmentally sensitive areas such as Alaska's inland passage.

Title:Galley Food Waste Disposal
Abstract:In order to comply with environmetal regulations and maintain its operational effectiveness, the U.S. Navy must examine alternative technologies for galley waste treatment and disposal. Recent developments in sewage and gray water treatment systems have addressed numerous shipboard applications with the exception of the galley waste stream. WASTECH international, Inc. has developed a number of innovative and alternative treatment technologies that are directly applicable to the U.S. Navy's galley waste treatment needs. These treatment technologies are capable of eliminating solids and producing an effluent potentially suitable for overboard discharge. Under Phase I of this project, WASTECH proposes to determine the feasibility of utilizing WASTECH technology for sucessfully treating shipboard galley waste. WASTECH will conceptually design a prototype galley waste treatment system that will provide the most economical and efficient means of shipboard treatment of galley waste. WASTECH's treatment system involves the microwave incineration of solids, as well as ceramic filtration of effluent to significantly reduce the suspended solids concentrations of dischage effluent. It is expected that information obtained from this Phase I project will make it possible to design and build a galley waste treatment system for an appropriate class of ships under SBIR Phase II, with commercialization for other classes of ships under Phase III. WASTECH anticipates commercializing the galley waste treatment components developed under Phase I and Phase II of this proposal as part of its overall business plan to develop products for its residentialnad commercial markets including the military (both marine and land-based), commercial marine, and food service markets.

Title:Novel Breakers Utilizing Piezoresistive Composite Materials
Abstract:This proposal introduces a dramatic departure from conventional switching technologies. Unlike conventional high-voltage - high load breakers or switchers, the new technology possesses no gapping so considerations of arc quenching and gap size are non-issues. Unlike conventional breakers used by the Navy, the proposed technology does not rely on any mechanical interrupt mechanism. The novel approach offers an order of magnitude higher interrupt speed than previously noted as achievable in the literature or in available product specifications for existing U.S. Navy breaker supplied equipment. Due to its inherent electrical (as opposed to conventional mechanical) operation, this technology is amenable to remote condition-based maintenance on board ship. Remote implemented high-speed computer commanded interrupt or 2nd or 3rd tier shipboard management systems operators can achieve reset. The interrupt and reset speed are only constrained by the load sensing technology. Recent advances such in high-speed current load sensing, including recent research by the Navy itself, now offer remarkably fast triggering capability that will enable ultrafast interrupt, thereby minimizing both thermo-mechanical shock at the breaker itself. The proposed research will leverage recent advances by QorTek Inc. and Penn State University in polymers actuator design, piezoelectronic power systems and digitally controlled condition-based maintenance. The proposed is being developed with no cost mechanical support from our commercial partner Protek-Viking (see attached letter). The proposed technology directly fits in the main business areas of both QorTek and Face Corporation. Protek-Viking is currently developing a major launch of piezo-actuated circuit breaker products with multiple pending patents on the designs. The proposed technology development is directly in-line with this product launch.

Title:Shock Resistant Circuit Breakers Utilizing Smart Materials
Abstract:The U.S. Navy has long recognized that ship survivability depends critically on the smooth, uninterrupted operation of all electrical and electronic subsystems. These include weapon systems, communication and navigational systems, radar, propulsion systems, electric-hydraulic systems, and virtually every electronic and computer based piece of equipment onboard. However, with over 4,346 conventional circuit breakers onboard a typical DDG, these represent multiple Achilles' heels in the presence of shock and vibration. A typical Naval shipboard circuit breaker contains both thermal and magnetic trip mechanisms which are known to false trigger in the presence of even relatively minor shock impacts. Spectrum Research Corporation proposes to develop a new generation of high reliability Naval circuit breakers based on smart materials. Through the integration of magnetostrictive actuators, rheological dampers, and embedded intelligence, it is possible to develop a circuit breaker that is immune to all but physically destructive shock impacts. A secondary objective is to provide for field reconfigurability such that authorized personnel may customize overload trip points upon installation. In addition to comprehensive solid modeling and simulation studies, the Phase I deliverables shall include a fully functional benchtop prototype. The anticipated benefit of the Phase I effort is the demonstration of an actively controlled circuit breaker that offers superior immunity to shock and vibration. In addition, the benefit of field reconfigurability will allow a single smart circuit breaker to replace a whole product line of conventional circuit breakers. These devices will be especially suitable for use in seismic applications and transportation vehicles.

Abstract:An on-demand, automated readiness assessment product that objectively displays scored watch team performance across shipboard required combat systems mission areas while furnishing input to overall warfighting readiness assessment. Measurable criteria established focusing on Ship and Commanding Officer requirements will be evaluated relative to functional warfare area training requirements of FLTCINC, TYCOM and UNTL/NTTL, encompassing those discrete training objectives prescribed as training qualifications and certification standards. Assessment methodology focuses on graduated team performance over the IDTC Basic, Intermediate and Advanced phases as it progresses toward deployment certification. Incorporating diagnostic analysis to assess combat systems team performance shortfalls, it will provide remediation alternatives down to the individual skill level. Effects of simulated or actual combat systems degradations will be factored as they impact demonstrated team performance. Watch team mission readiness will be categorized using functional building blocks to examine specific performance within contributing warfare process elements. Governing measurable parameters developed will be tactical results based as extrapolated from TYCOM/ATG combat systems training objectives and as supported by data collection availability through passive taps. Prototype software GUI display using Windows technology will be a layered representation of each primary mission's functional building blocks depicting overall warfare performance relative to assessed combat systems team readiness. Automated performance assessment methodology could be specifically adapted to support broad commercial application where simulation/CBT based team training is used to teach a series of tasks or functional processes as essential ingredients for business success. Any production activity that, through task analysis, equates training achievement to measurable output could be assessed in terms of comparable performance readiness. Such areas might include power generation plant operation, manufacturing assembly processess, telemarketing, banking or sales promotion wherever definable objective performance standards are established.

Title:Ship Mission Readiness Measurement System
Abstract:Current Naval training systems typically collect ground truth and operator performance data during training events. The data collected is usually a function of the particular training system used during the training event. Data generated from the training event is compiled into after-action debrief products. These after-action products often provide unrelated and uncorrelated data that would be extremely useful in assessing overall mission effectiveness if properly identified and meshed with other performance parameters. Currently, no measurement system exists that can both interface with various training systems and automatically collect and process mission effectiveness data in a consistent way across training events and training systems. DSR proposes to explore the feasibility of defining an architecture that combines contemporary training and readiness tools [i.e., Afloat Training Exercise and Management System (ATEAMS) and the training debrief capabilities of the Battle Force Tactical Training (BFTT) system], to support an automated Ship Mission Readiness Measurement system. This system will identify and record the readiness and performance attributes through measurable parameters for watch-station and watch-team performance. It will then collate relevant performance data to assess system and personnel performance. The goal is to achieve a more robust ship readiness assessment for use by all command structures. The benefits of this effort include the identification of an automated system capability to determine operator, watch-team, and unit readiness. The architecture for providing this capability will capitalize on the current data gathering functionality inherent in existing shipboard training systems. This type of capability can also be leveraged to other systems and environments where there is a need for individual, sub-team, and full-team training and assessment in other Navy, military branch, and private sector arenas.

Title:Ship Mission Readiness Measurement System
Abstract:Increased demands on the surface Navy coupled with force downsizing and other factors have made maintaining readiness a key issue. The goal of this project is to develop methods and supporting technologies for measuring readiness in the surface Navy. In Phase I, we will first determine a set of mission areas and functions that we will use for developing and demonstrating our readiness assessment and diagnosis methods and tools. We will also define constraints on the technology as a function of ship features and other practical issues that may limit our options. Finally, we will follow a process described in this proposal on the sample set of ship and crew functions to demonstrate how the methods and technologies assess crew readiness. This process includes the determination of tasks critical to function success, the identification of a smaller set of performance indicator tasks, task analysis and the development of measures of effectiveness on the performance indicator tasks, the development of automated and manual supporting technologies for assessment, and the development of a summary readiness assessment tool. At the end of Phase I, we will have tested this process and determined its practicality and utility in assessing crew and ship readiness. By being able to assess readiness objectively and efficiency, the Navy will be able determine deficiencies in readiness before a ship and crew goes on a mission for which they are unprepared. This could save lives and avoid international embarrassments. Additionally, the tools we propose to develop will provide diagnostic information that will help the ship and crew determine the best path to achieving better readiness as well as providing ways to measure progress along that path.

Title:Aerosol Can Voiding Device
Abstract:Apogee Engineering Inc. proposes to R&D a system for separating partially empty aerosol cans into: empty cans, plastic parts, residual liquid and volatile components. The approved disposal method is collection in steel drums, where one drum full of 150 cans is a drum of Excess Hazardous Waste for disposal onshore at costs averaging $2.83/can. Apogee proposes the separated components can be disposed of in an economical and environmentally safe manner for about $0.034/can. The complete system will consist of: improved can voiding device,volatile components management system, volatile component adsorption system and valve removal device for separating the plastic parts from metal parts. Principal investigator: Gary L. Gardner Sr.,P.E., chemical engineer with 40 years experience in diverse technologies.The R&D will establish, in partnership with the Navy, a design basis for the complete system. Existing systems allow excessive volatile components to escape into the immediate atmosphere of the systems and fail to separate the plastic components. A superior system with optional features will be developed that meets the needs of the Navy, other governmental agencies and the private sector. Optional designs allow marketing of less expensive models for entities not requiring the stringent Navy standards. Benefits to the Navy, as a result of this research and development,will be the design of a safer and easier to use aerosol can voiding/disposal system for use onboard ships. The system will: (1) puncture partially empty aerosol cans safely with zero exposure of the contents to the operator; (2) adsorb the hazardous components from the punctured aerosol cans, reducing emissions to essentially zero; (3) collect the liquid contents in a liquid containment drum for disposal as ordinary liquid waste; (4) separate the plastic containing valve assembly from the empty can so that the empty can and plastic components can be disposed of properly. The commercial applications are numerous and, most importantly, beneficial to the environment: minimizing co-mingled waste in landfills; minimizing release of volatile gasses into the atmosphere; minimizing waste by the cruise ship industry, the health care industry, the hotel/lodging industry and other similar industries.

Title:Aerosol Can Evacuation and Compaction Device for Shipboard Use
Abstract:Due to the limited space onboard a naval vessel, new and improved methods must be investigated and developed to contain, handle, and store many types of waste products of which one is aerosol cans from personnel and maintenance. Manual aerosol can evacuating equipment exists, but our approach is to construct and test our automated can crusher/evacuator device that will evacuate the contents and then compact the cans to two inches in height. This will significantly reduce the amount of space needed for the storage of waste aerosol cans and the unit will operate off of ships power allowing for any user to just insert the can and close the door, leaving the crushing and evacuating to the unit, depositing waste fluid into one drum and ejecting the crushed can to another drum. This system will not only reduce the amount of space needed for waste storage, but it will also make it easier to contain and handle the waste products from the evacuated aerosol cans. The system will also be completely expandable with a variety of add-on options including an auto feeder for hands free operation. The system that is being proposed will have concrete benefits both functionally and economically the first benefit is that the space needed to store the waste will be reduced by an estimated 65% to 75%. This is a direct result from the compaction of the cans. The system is operator safe and more environmentally friendly than manual methods. The unit will be able to accommodate any size can. The scrap metal from the cans can be sold and thus the system is self-subsidizing. The hazardous waste costs will be reduced due to the fact that the metal from the cans is being removed as a component of the hazardous waste. The only hazardous waste will be the actual contents of the can. The waste will also be easy to handle since the can waste contents and the scrap cans can all be stored within 55-gallon drums. The unit will be very simple to operate and periodic cleaning will be the majority of the maintenance and up keep needed, taking minimal time for personnel to operate or maintain. All the components being mechanical will be easy to service and replace if necessary. The entire system will be easy to move, mount, and use. The options for the system can greatly make the system even more efficient and economically attractive to potential customers through automatic feeding of multiple cans, and automated batch processing. It is beneficial for private consumers who recycle as well as expanding the general municipal can recycling market for the public to now include aerosol cans. Larger units to handle the amount of municipal aerosol can waste, equipped with auto feeders, will allow for greater recycling capabilities for municipalities all over the country and the world.

Title:Low Hydrodynamic Drag Cable for Mine Countermeasures
Abstract:In this topic we explore minimum drag towing cable configurations for underwater mine countermeasure equipment. The drag of the cable itself can be a significant portion of the overall system drag, and the goal is to determine, for a given mission (tow depth and speed), the best combination of cable length and sectional shape, through a constrained (volume) optimization process. This will allow a smaller/faster/cheaper system solution. We will demonstrate a flexible, animated real-time finite segment hydrodynamic model as a development tool, and partially validate it in Phase 1 with full scale testing of simple bodies towed from an instrumented planing craft at varying depth, speed, and cable length. This should answer the question: Is a `streamlined' cable better than a simple, long and smooth cylindrical one? If the shaped cable looks worthwhile, we will pursue a streamlined composite towing cable with an optimized profile and folding, trailing `fins' to prevent kiting. Cable drag is a major consideration in the fishing industry, the oil industry and other commercial interests which tow object through the water. Low drag cables would apply to any of these efforts.

Title:High Strength Fiber Optic Sensor Grating Arrays
Abstract:IOS proposes to develop high strength fiber Bragg grating (FBG) sensor arrays by fabricating high-quality FBGs in the core of conventional optical fibers without removing their protective polymer coatings. In Phase I, IOS will fabricate gratings that have reflectivities of at least 5% for the target wavelength, a bandwidth (FWHM) of no more than 0.8 nm, sidebands more than 2 nm from the center and lower in reflectivity by at least 30 dB, and an insertion loss of less than 0.1 dB. IOS will also use this technique to form several fiber Bragg gratings on a single fiber. Each grating will have a designated wavelength in the 1530 nm to 1565 nm range, and will conform to its designated wavelength to within at least 0.1 nm. IOS will verify that the fiber strength is not degraded by the process used to impose the Bragg gratings. Success on this objective will be shown by demonstrating that the fiber can withstand a pressure of at least 300 ksi both before and after imposition of the gratings. Fiber Bragg grating arrays can be used as sensors to detect sound, strain, temperature, and a number of other important variables. These sensors can be deployed over great distances, without electromagnetic interference, in environments that are typically hostile to normal electronic gear. The fiber gratings to be developed in this project will have better optical performance, will be less expensive to fabricate, and will be more rugged than currently produced gratings. These high strength in-fiber gratings will find wide use in a variety of military, medical, research, and commercial applications in fiber sensors and telecommunications.
