A UNIQUE HIGH TEMPERATURE, HIGH PRESSURE GASEOUS PHOTOCHEMICAL REACTOR WITH OPTICAL AND MASS SPECTROMETRIC SPECIES DETECTION CAPABILITIES WILL BE DESIGNED. THE PROPOSED DESIGN, UTILIZING AEROCHEM'S EXPERIENCE IN CONSTRUCTING AND USING SIMILAR APPARATUS, WILL EXCEED THE UPPER TEMPERATURE AND PRESSURE SPECIFICATIONS GIVEN IN THE SOLICITATION IN ORDER TO GIVE THE INSTRUMENT GREATER UTILITY. ALTERNATE ...

A NEW DESIGN CONCEPT FOR ELECTRONIC SHELTERS USING SOME OF THE ADVANCED MATERIALS SUCH AS CONDUCTIVE COMPOSITES, AND REINFORCED CONDUCTIVE SILICONE FABRICS WILL BE TESTED. THE MOST RELEVENT APPLICATION PARAMETERS SUCH AS CONDUCTIVITY OF THE COMPOSITES AND FABRICS, THE JOINING MECHANISM TO ENSURE ELECTROMAGNETIC COMPATIBILITY, THE FLEXIBILITY, THE TRANSPORTABILITY AND TOTAL SYSTEM WEIGHT WILL BE AD ...

ALTHOUGH THERE ARE NO INTRINSIC CONFLICTS FOR THE SAME MATERIAL SYSTEMS TO ACHIEVE BOTH THE RADAR ABSORPTION AND THERMAL SUPPRESSION CHARACTERISTICS THERE EXISTS NO COMMERCIAL PRODUCT THAT HAS THE DESIRED DUAL PROPERTIES. A THEORETICAL CALCULATION ON THE FEASIBILITY OF SEVERAL PROPOSED MATERIAL SYSTEMS WILL BE PERFORMED. THE CALCULATIONS ARE BASED ON A MEAN FIELD THEORY FOR DIELECTRIC PROPERTIES. ...

A POLYIMIDE BASED POLYMER ALLOY IS PROPOSED TO BE USED AS THE MATRIX FOR A QUARTZ FILLED MULTILAYER CIRCUIT BOARD. POLYIMIDE WHICH HAS THERMAL EXPANSION COEFFICIENT (TEC) OF 30 PPM/DEG C IS SUBSTANTIATLY LOWER THAN THAT OF EPOXY (50-60 PPM/ DEG C). THE POLYMER ALLOY WHICH CONSISTS OF RIGID-RODLIKE MOLECULES, HOWEVER, WILL HAVE TEC AS LOW AS 10-20 PPM/DEG C. QUARTZ FIBER FILLED IN DIFFERENT GEOMETR ...

MMIC YIELD IS THE SIGNIFICANT FACTOR IN DETERMINING BOTH CHIP COST AND LEVEL OF INTEGRATION. IN ORDER TO MAXIMIZE YIELD, IT IS NECESSARY TO ESTABLISH A CONSISTENT, REPRODUCIBLE PROCESS CONTROL, COUPLED WITH CREATIVE CIRCUIT DESIGN TECHNIQUES USED TO CREATE SHIP SETS WHICH ARE TOLERANT TO PROCESS VARIATIONS. A LARGE PROPORTION OF THE FINAL COST FOR THE END PRODUCT IS RELATED TO THE ASSEMBLY AND FIN ...

WAFER PROBING IS THE CRITICAL LINK BETWEEN WAFER FABRICATION, AND DEVICE PACKAGING OR HYBRID SUBSYSTEM INSERTION. FOR GAAS MMICS TO BE COST EFFECTIVE, THEY MUST BE TESTED IN A MANNER THAT IS RELIABLE, FAST, AND EFFICIENT. THIS PROPOSAL DESCRIBES A PROGRAM TO DEVELOP EQUIPMENT AND TECHNIQUES FOR HIGH RATE, HIGH VOLUME MMIC WAFER PROBING. PHASE I OF THIS PROGRAM WILL INCLUDE AN EXPERIMENT USING EXIS ...

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO REDUCE THE SIZE, WEIGHT, AND COST OF THE RELAY OPTICS OF THE AIRCRAFT HEAD UP DISPLAY (HUD), BY REPLACING IT WITH TRANSMISSION HOLOGRAPHIC LENSES. HOLOGRAPHIC LENSES ARE VERY LIGHT AND CAN BE MANUFACTURED AT VERY LOW COSTS. APPLICATIONS OF HOLOGRAPHIC LENSES TO HUD WERE LIMITED IN THE PAST, DUE TO WIDE SPECTRAL BAND OF THE HUD - CATHODE RAY TUBE (CRT). HO ...

A SPECTRALLY AGILE BASED UPON A TUNABLE FILTER CAN EFFECTIVELY MEASURE INFRARED BACKGROUND, TARGETS, AND OBSCURANT CLOUDS. AN INTEGRATED OPTICS INTEGRATED FILTER (IOTF) PLACED IN FRONT OF THE SENSOR FOCAL PLANE OR INTEGRATED WITH THE FOCAL PLANE DETECTORS CAN BE USED TO SELECT WAVEBAND LOCATION AND BANDWIDTH IN THE INFRARED. A SPECIFIC CONCEPT FOR THE FILTER IS PROPOSED BASED UPON A MACHZEHNDER IM ...
