ASPEN SYSTEMS PROPOSES AN INNOVATIVE APPARATUS FOR REMOTE MEASUREMENT OF CLOUD AND FOG PARAMETERS, SUCH AS WATER CONTENT. THIS LIDAR APPARATUS USES STATE-OF-THE-ART LASER TECHNOLOGY TO MEASURE THE PROPERTIES OF A CLOUD OR FOG (CONSTITUENT, WATER DROPLET SIZE AND CONCENTRATION) REGARDLESS OF AMBIENT LIGHT CONDITIONS (DAY OR NIGHT) OR LOCATION OF DEPLOYMENT (GROUND BASED OR AIRBORNE). THE PROPOSED L ...

ASPEN SYSTEMS PROPOSES TO DEVELOP HIGH DIECTRIC CONSTANT (K) SELENIUM POLYMERS TO MEET THE DESIGN OBJECTIVES OF HIGH ENERGY DENSITY CAPACITORS (HEDC) FOR ENERGY STORAGE IN PULSED POWER SYSTEMS (15 TO 45 MJ/kg). IN THE PROPOSED PHASE I WEL WILL SYNTHESIZE HIGHLY PROCESSABLE, Se BASED POLYMERS AND FABRICATE SAMPLES OF FILM FOR DIELECTRIC ANALYSIS. INITIAL, RIGOROUS CALCULATIONS HAVE BEEN PERFORMED B ...

STRATEGIC DEFENSE SYSTEMS NEED TO DEVELOP AUTOMATED TARGET RECOGNITION (STR) SUB-MUNITIONS THAT CAN IDENTIFY FRIEND OR FOE AND FOR SURVEILLANCE. CURRENT ATR METHODS HAVE PROBLEMS CLASSIFYING HIGHLY VARYING IMAGES OF 3D OBJECTS. THE PROPOSED WORK AIMS TO OVERCOME SOME OF THESE DIFFICULTIES BY BUILDING A NEURAL NETWORK ATR SYSTEM THAT LEARNS BY EXAMPLE. THE OBJECTIVE OF THE PROPOSED PHASE I EFFORT I ...

MATERIALS LASERS ALUMINUM-FREE HETEROEPITAXIAL SILICON III-V'S KOPIN CORP WILL DESENSITIZE THE DELETERIOUS IMPACT OF THE INHERENT DEFECTS IN HETEROEPITAXIAL FILMS FORMED ON SILICON i.e., BY THE SELECTION AND USE OF "ALUMINUM-FREE" SUBSTITUTE MATERIALS WITH SUITABLE PROPERTIES. EVIDENCE EXISTS THAT SUCH Al-FREE COMPOUNDS OFFER THE PROSPECT OF USING MATERIALS WITH A RELATIVE IMMUNITY TO THE DEFECTS ...

GALLIUM NITRIDE AND ALUMINUM NITRIDE FILMS ARE CURRENTLY GROWN ON SUBSTRATES WITH SUBSTANTIALLY DIFFERENT CRYSTAL STRUCTURES AND ATOMIC SPACING. FILMS GROWN ON SUCH SUBSTRATES HAVE POOR CRYSTALLOGRAPHIC PROPERTIES WHICH RESULT IN DEGRADATION OF ELECTRICAL PROPERTIES AND DEVICE PERFORMANCE. IMPROVED SUBSTRATE MATERIALS ARE REQUIRED WHICH WILL PERMIT THE GROWTH OF PERFECT FILMS OF GaN AND AlN. THE F ...

THIS RESEARCH WILL DEVELOP AN ULTRA FAST SCHEME FOR DETECTION OF ELECTROMAGNETIC SIGNALS BASED ON THE INHERENT ELLIPTICAL SYMMETRY OF MULTI-STABLE DEVICES, AS PROPOSED BY SAET AND VIVIANI. THE RESULT IS A STATE SPACE MAPPING WHICH CAN BE USEFULLY APPLIED FOR REAL-TIME DETECTION, CONTROL AND MONITORING FOR A VARIETY OF SIGNALS OF INTEREST, BY DEVELOPING SUITABLE HARDWARE BASED ON A NOVEL GENERALIZE ...

HIGH POWER ELECTRONICS DEVICES SUCH AS POWER SWITCHES GENERATE LARGE HEAT FLUXES, WHICH MUST BE REMOVED, OR THE DEVICES WILL EXCEED THEIR UPPER TEMPERATURE LIMITS. MOST COOLING METHODS ARE INCAPABLE OF REMOVING SUCH LARGE HEAT FLUXES. MERIX CORPORATION PROPOSES TO DEVELOP A HIGH EFFICIENCY COOLING DEVICE TO REMOVE THESE HEAT FLUXES IN A PRACTICAL MANNER. THE DEVICE WILL FORM THE BACKBONE OF AN INT ...

DIODE-PUMPED SOLID-STATE LASERS HAVE THE ADVANTAGE OF BEING ALL-SOLID-STATE DEVICES WITH OVERALL EFFICIENCIES OF SEVERAL PERCENT AND LONG OPERATING LIFETIMES, SINGLE-MODE SOLID-STATE LASERS ARE USEFUL FOR A NUMBER OF APPLICATIONS RANGING FROM COMMUNICATIONS TO LASER RADAR. HIGH AVERAGE POWER OPERATION REQUIRES EXTENSIVE COOLING OF THE LASER CRYSTAL TO PREVENT THERMAL DEGRADATION OF THE BEAM. SOLID ...

N/A

THIS PHASE I PROPOSAL IS CONCERNED WITH THE DEVELOPMENT OF A VERSATILE WRITE/READ INTERCONNECTION DEVICE FOR BIT AND HOLOGRAPHIC ENCODED MEMORIES. THE PROPOSED DEVICE CONSISTS OF AN ARRAY OF MIRRORS WHOSE FOCAL LENGTHS CAN BE INDIVIDUALLY CONTROLLED BY A VLSI CHIP CONSISTING OF A 2-D ARRAY OF IDENTICAL DRIVE CIRCUITS. THE VLSI CHIP IS BUMP-BONDED TO THE ONE SIDE OF AN OPTRON PROPRIETARY COMPONENT ...
