CONVENTIONAL INTERCONNECT AND SWITCHING TECHNOLOGY HAS BEEN IDENTIFIED AS A LIMITATION IN HIGH THRUPUT PROCESSORS AND COMPUTERS. WAFER SCALE INTEGRATION IS ONE TECHNIQUE TO RESOLVE INTERCONNECT PROBLEMS. METHODS OF INTERFACING TO WAFER SCALE DEVICES WILL RESOLVE INTERCONNECT PROBLEMS. METHODS OF INTERFACING TO WAFER SCALE DEVICES WILL REQUIRE OPTICAL INTERCONNECT TECHNIQUES. IMPLEMENTING COMMUNICA ...

HELMET MOUNTED DISPLAY (HMD) SYSTEMS PRESENT MANY POTENTIAL BENEFITS TO OVERCOME CURRENT DISPLAY LIMITATIONS OF EXTRAVEHICULAR SPACESUITS. IN THIS PHASE I EFFORT WE PROPOSE TO INVESTIGATE THE PRELIMINARY OPTICAL AND MECHANICAL DESIGNS FOR INCORPORATING AN HMD SYSTEM WITH THE EXTRAVEHICULAR MOBILITY UNIT (EMU). THE DESIGN GOALS ARE TO PROVE THE FEASIBILITY OF THE HUD SYSTEM ON THE EMU WHILE PROVIDI ...

LASER BEAM SCANNING IS REQUIRED TO SUPPORT SPACECRAFT TERMINAL RENDEZVOUS, STATION-KEEPING, AND DOCKING. CURRENTLY, ACOUSTO-OPTIC BRAGG CELLS OFFER THE BEST AVAILABLE MEANS OF SCANNING A LASER BEAM WITHOUT USE OF MOVING MECHANICAL PARTS. BRAGG CELLS, HOWEVER, ARE LIMITED BY THEIR SMALL ANGULAR RANGE, LOW SCAN SPEED, AND HIGH POWER REQUIREMENTS. WE THEREFORE PROPOSE AN ADVANCED INTEGRATED ACOUSTO-O ...

THE OVERALL OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP A LOW POWER, COMPACT MULTICOLOR, FLAT PANEL DISPLAY. OUR APPROACH IS BASED ON ILLUMINATING A 3-COLOR PHOSPHOR SCREEN WITH AN INFRARED SEMICONDUCTOR LASER DIODE AND SCANNING IT WITH AN INTEGRATED OPTICS BASED LOW POWER LASER SCANNER. APA OPTICS IS DEVELOPING A LASER SCANNER WHICH HAS NO MOVINGPARTS, IS VERY COMPACT, AND HAS THE POTENTIALS O ...

WE PROPOSE THE DEPOSITION OF HIGH TC YBACUO LAYERS, USING ATOMIC LAYER CVD OVER A COMPOSITE ALXGA1-XAS/ALXGA1-XN/SAPPHIRE SUBSTRATE. THE UNIQUE ATOMIC LAYER PROCESS IS EXPECTED TO REDUCE THE EPITAXY TEMPERATURE WELL BELOW THAT REQUIRED FOR CONVENTIONAL MOCVD. THIS WILL ELIMINATE THE NEED FOR A POST DEPOSITION ANNEAL. OUR SUBSTRATE STACK IS ALSO UNIQUE. IT HAS A DIELECTRIC CONSTANT MUCH LOWER AND T ...

THE KEY PROBLEM TO BE ADDRESSED IN PHASE I OF THIS PROJECT WILL BE TO DETERMINE THE FEASIBILITY OF A NOVEL POSITION MEASURING SYSTEM FOR A FAMILY OF COMPUTER CONTROLLED MACHINE TOOLS. THE MULTIPLE LASER MEASUREMENT SYSTEM (MLMS), WHICH FORMS THE BASIS OF THIS PROPOSAL, WILL MEASURE THE (X, Y, Z) POSITION OF THE CUTTING HEAD DIRECTLY AT RATES AND ACCURACIES SUFFICIENT FOR CLOSED LOOP POSITION CONTR ...

RECENTLY, MUCH ATTENTION HAS BEEN FOCUSED ON THE USE OF ILLICIT AND/OR DESIGNER DRUGS BY PEOPLE FROM ALL FACETS OF AMERICAN LIFE. ONE OF THE MOST POPULAR OF THE DESIGNER DRUGS ARE THE FENTANYLS WHICH ARE VERY POTENT AND VERY DIFFICULT TO DETECT IN BIOLOGICAL FLUIDS. THESE POTENT DRUGS ARE BEING USED BY PEOPLE FROM ALL SEGMENTS OF OUR SOCIETY INCLUDING HEALTH CARE WORKERS, MILITARY PERSONNEL, AND P ...

FUTURE MILITARY AVIONICS SYSTEMS WILL REQUIRE AT LEAST AN ORDER OF MAGNITUDE IMPROVEMENT IN MEAN TIME BETWEEN CRITICAL FAILURES. TO ACHIEVE THIS GOAL INNOVATIVE FAIL-SAFE FAULT-TOLERANT ELECTRONIC SYSTEM DESIGN CONCEPTS WILL BE NEEDED. THE APPROACH PROPOSED BY DAINA WILL BE BASED ON THE USE OF EXTERNAL ENVIRONMENT DATA, BUILT-IN RELIABILITY MODEL, ADAPTIVE STATISTICAL SYSTEM STATE AND PARAMETER ES ...

THE OVERALL GOAL OF THIS PROJECT IS TO IMPROVE PROGRAMMER PRODUCTIVITY AND TO REDUCE THE COST OF DEVELOPING PERSISTENT DISTRIBUTED APPLICATIONS. THE APPROACH PROPOSED IS TO RESEARCH AND DEVELOP A TOOLKIT FOR PERSISTENT DISTRIBUTED PROGRAMMING WHICH (1) PROVIDES LANGUAGE SUPPORT FOR EXPRESSING PERSISTENCE AND DISTRIBUTION OF APPLICATIONS (2) SUPPLIES MECHANISMS IMPLEMENTING PERSISTENCE AND PROGRAM ...

THE COMPLETE DESIGN IS PRESENTED WITHIN THIS PROPOSAL FOR A SYSTEM WHICH WILL PROVIDE A PRECISE, ONE-STEP CONVERSION DIRECTLY FROM A PULSE TRAIN INPUT TO A DIGITIZED PULSE RATE OUTPUT. IT IS A DISTRIBUTED PROCESSOR SYSTEM EMPLOYING A MASTER CONTROL PROCESSOR AND FROM 2 TO 30 IDENTICAL PULSE MODULES. THE PULSE MODULE IS A STANDALONE UNIT WHICH PERFORMS THE PULSE PERIOD MEASUREMENT. THE MICROPROCESS ...
