Adaptive spatio-temporal filtering methods are proposed which are inherently suitable to utilizing many sensors and actuators to achieve superior control and monitoring of structures for vibration and shape control and damage detection. When utilizing large numbers of sensors and actuators, failure detection and failure recovery become important issues. The adaptive spatio-temporal filtering metho ...

This Phase II SBIR program will develop and demonstrate a high temperature polymer matrix composite system for use in a structural missile component in multiple BMD systems. Under this program, an extensive database of thermal, mechanical, and electrical properties will be established for the composite system, conceptual designs for the missile component structure will be generated and optimized, ...

At hypersonic flow conditions, the flow field around reentry vehicles is ionized, resulting in electro-optical emissions, detectable radar cross-sections, and attenuation of signals transmitted through the plasma. Ablative heat shields may further increase the levels of electrons in the plasma around the hardbody and in the wake. We propose to extend an existing high-fidelity computational fluid d ...

We offer an approach to a multiple-order-of-magnitude processing speed/efficiency improvement in vector quantization (VQ) data/image compression, automatic target recognition/classification, and time signal/signature classification. We base our approach on an algorithmic breakthrough, the TABULAR NEAREST-NEIGHBOR ENCODER (TNE), which we discovered and partially developed last year. This algorithm ...

Electrochemical capacitors (supercapacitors) are rechargeable devices which deliver high powers for limited periods. The objective of this proposal is to provide new, low-cost approaches for significantly increasing the power and energy storage of carbon supercapacitors. We do this in two ways: A) We improve power by preparing carbon in the form of a contiguous, conductive foam structure. This is ...

CdSe, a wide bandgap semiconductor, combining high resistivity, good carrier trans-port properties, and large average Z number is ideal for use as a room-temperature x-ray and y-ray detector. In the x-ray regime, the large bandgap (-1.7 eV) of GdSe eliminates the need to cool the crystal in order to reduce thermal noise. Si and Ge detectors must be cryogenically cooled, which precludes their use i ...

A six-month, $91,305 Phase I SBIR program is proposed to perform ceramic-composition R&D aimed at cryogenic capacitors for the 120 - 240 K temperature range. Candidate compositions from three families of ceramics will be made under subcontract by NexTech Mat'ls Ltd and measured by CeramPhysics, 120 - 240 K (dielectric constant, loss tangent, frequency dependence, electric-field dependence, dielect ...

Reductions and reallocations of telemetry wireless bandwidth have prompted the need for DoD agencies to adapt to operation in more restricted and less desirable frequency spectrum. Telemetering systems must evolve to address these frequency allocation changes, while retaining operational characteristics that are vital to MDA mission success. The design and implementation of high performance transm ...

Glassy liquid crystals (GLCI represent a new emerging class of advanced organic materials which have significant potential for being readily processed into uniform optical quality thin films. In this proposal, we propose to develop high-performance optical filter and polarizer technology specifically for laser protection applications. The proposed GLC-based optical filters are specifically well su ...

Optical switches are fundamental components of survivable fiber network architectures. They are required to enhance the performance of fiber optic networks through load shifting and to provide disaster recovery when communication links are lost. Optical networks will likely be employed in the next generation of military air- and spacecraft (e.g. JAF) to provide communication links between avionic ...
