DARPA wishes to exploit MEMS technology to develop a tactical grade INS. SatCon is proposing to develop an angular rate sensor combined with an accelerometer which are microfabricated on a single "chip" using the LIGA lithographic process. The accelerometer element employs a rebalanced cantilever, oriented orthogonally to the substrate, while the rate sensor uses a vibrating cylinder sensitive t ...

Performance benefits to systems employing an Electrically Steerable Antenna (ESA) are numerous. Included are rapid beam scanning, beam agility, and the performance of multiple functions such as surveillance and target tracking. These gains are obtained at the expense of large increases in system cost and weight. For many space and aerostat applications, the classical ESA architecture of one T/R ...

THE OBJECTIVE OF THE PHASE I RESEARCH IS TO DETERMINE THE TECHNICAL FEASIBILITY OF THE DEVELOPMENT OF A LONG RANGE RADIOACTIVE PLUME TRANSPORT MODEL/CODE FOR THE NRC. THIS CODE WOULD BE USED TO SIMULATE THE MOVEMENT, DISPERSION, DECAY, AND DEPOSITION OF RADIONUCLIDES RELEASED FROM SEVERE NUCLEAR REACTOR ACCIDENTS, SUCH AS THE CHERNOBYL ACCIDENT. IT IS DESIRED THAT ALL RELEVANT PHYSICAL AND CHEMICA ...

Modern fligt control systems rely on hardware redundancy to overcome failures of sensors and actuators. This is an expensive approach which does not make use of analytical redundancy present in a flight control system. Analytical redundancy is achieved by comparison of sensor outputs over time and across sensors using physical and identified models. We propose here methods to detect failures us ...

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 program is proposed to investigate and develop thin buried oxide (BOX) SIMOX with quality of silicon and BOX layers suitable to support fully depleted SOI applications with minimum feature size at and below 0.18 um. In Phase I, novel, low dose SIMOX processes in low energy (less than 100keV) regime will be examined. This approach will allow to tailor thin film layer thicknesses by proper choic ...

Etalon has recently demonstrated a fundamentally new display technology based on Microelectromechanical (MEM) Strucutres. Exploiting the phenomena of interference, these interferometric modulators (IMods) are simple membrane structures whose colors change when deformed electrostatically. IMods have already demonstrated drive voltages of 25 volts, response times of 1 microsecond, and prominent hy ...

Many simulations environments, particularly those used for training purposes, employ simulated human behavior. To date, users frequently complain that such simulated behavior is not very intelligent and easy to "game" thus reducing the effectiveness of the training. We propose to improve intelligent agent technology through improved techniques for eliciting expert problem solving knowledge on wh ...
