AbTech Corporation proposes to apply its unique Statistical Network ModelingTM technology to develop a non contact prognostic assessment tool that 1) acquires, processes, and analyzes electronic radiated signal data, 2) learns the expected characteristics and patterns of specific radiated signals measured from microelectronic semiconductor devices using AbTech's statistical network modeling techno ...

The opportunity addressed in this proposal is a fast-acting cryogenic injection valve for pulse detonation rocket engines (PDREs), which are predicted to significantly out-perform current state-of-the-art chemical deflagrative rocket propulsion systems. The developed valve would allow high mass flow rates to be achieved with fast response times, all at minimum cost, weight, power, and volume. Th ...

The need for compact solid state ultraviolet light sources includes clinical light sources for a variety of surgeries, analytical instrumentation sources and communications systems based on shorter wavelengths that will be able to handle higher information densities. Such advanced optoelectric applications demand totally new materials. Of those available, silicon carbide is the most promising for ...

Integration of many different devices on a single silicon carbide (SiC) substrate is necessary to realize the full potential of high temperature or high power devices for markets ranging from industrial and consumer to military systems to transportation power and control. Integration requires that the entire device package, individual devices, contacts and interconnect materials, be ...

The III-V nitrides, (Al, In, Ga)N, are promising materials for high temperature, high power and high frequency devices due to the wide bandgaps, high electron saturation velocity and high electronic mobility transistor (HEMT) structures available in this alloy system. These devices would find wide-spread commercial use as power amplifiers in base station transmitters for personal communications ...

Commercially viable silicon carbide device manufacturing processes depend on an ability to grow'low defect density epitaxial layers. Low defect density epitaxial layers start with pristine SiC substrate surfaces. Epi-ready pristine SiC surfaces are not commercially available. The results of this-programme should remedy this. In Phase I we will demonstrate a cost-effective, reproducible ex-situ sur ...

The technique for accurately measuring the positions and orientations of targets in relation to a fixed reference is of fundamental importance to a number of military and commercial applications. For example, in the simulation experiments for testing of installed, integrated avionics, the configuration geometry data for hundreds of test assets, each having six-degree-of-freedom must be automatica ...

The intent of this program is to develop workable concepts that will result in commercial and military high performance, covert, low cost, adaptable antennas in gain, coverage, and a variety of equipment applicability for hand held use. Ideally, the program will result in a technology capable of significantly foreshortening antennas (4:1) while maintaining low losses, hemispheric coverage, novel ...

Shipboard electrical casualty faults can produce destructive voltage transients and outages that impair ship capacity for casualty fight through. Recent work on relay algorithms to detect faults and coordinate multiple circuit protection devices (CPDs) has demonstrated high-speed relay algorithms capable of reliably detecting transient events within several microseconds of their occurrence. These ...
