Spire and its subcontractor, Westinghouse/Norden Systems, propose development of color, thin film electroluminescent (TFEL) head mounted displays (HMDs) using passive matrix addressing and indium bump-bonded drive electronics. Passive matrix addressing vastly simplifies fabrication and improves manufacturing yields by decreasing the number of high voltage drive transistors required for display op ...

A demonstration of Broadband Code Division Multiple Access (CDMA) for PCS communications overlaid in the 800 MHz AMPS cellular band will be conducted. Broadband CDMA using direct sequence spread spectrum has significant military advantages of jamming immunity and low probability of intercept. It is also the most promising of the new concepts for high capacity commercial cellular radio because of ...

Capturing the rationale behind decision making in design plays an important role to explain a design, redesign and/or reuse an existing design. Existing design rationale models suffer from the lack of integrating rationale with the design process. The integration is crucial for the domain of software design due to its complexity. A model for design rationale capture and its related knowledge ba ...

This work offers an innovative approach to predicting system behavior (in terms of reliability and performance) based primarily on the structural characteristics of a formal functional specification. The mechanism for process composition is codified in the CSP-to-Stochastic Petri net (CSPN) toll. CSPN supports systematic specification, automatic translation and subsequent augmentation (e.g., fai ...

Mayflower Communications proposes to substantially improve the reliability of Global Positioning System (GPS) receivers under jamming using a combined adaptive antenna and temporal filter solution that incorporates low cost, small size, and low power requirements. The objective is to provide up to 50 dB of additional interference protection for both military and commercial GPS systems at an affor ...

SatCon Technology Corporation proposes to develop the next generation power controller module aimed at the integrated control and power functions desired for the Power Electronics Building Block (PEBB) which has broad goverment and commercial interest. Building on power hybrid technology advances made by SatCon during participation in Chrysler Corporation's "Patriot" Hybrid Electric Race Car Prog ...

The success of DoD's thrusts in Global Surveillance and Precision Strike depends critically on the ability to perform Automatic Target Recognition (ATR) and Hostile Target Identification (HTI). The technologies of modeling, sensor data fusion and adaptive intelligent image processing are key to the success of ATR and HTI. An innovative approach to intelligent model-based image processing and tar ...

We propose here new methods for system identification and active feedback control of axial flow compressors under conditions of incipient rotating stall and surge in the presence of inlet distortions. The nonlinear Moore-Greitzer model of rotating stall, which has proven useful for both simulation of rotating stall/surge dynamics of axial compression systems and for control design studies, will b ...

The detection and recognition of man-made objects under foliage conditions requires the use of VHF/UHF ultra-wideband (UWB) radars such as P-3/SAR system developed by ERIM for NAWC/AD and DARPA. At low frequencies and long wavelengths, most of the scatters are in the Rayleigh scattering region and their RCS is low, which enables foliage penetration. However, this also results in a small number o ...
