EPITAXX PROPOSES TO MERGE THE BEST ASPECTS OF HYDRIDE VAPOR PHASE EPITAXY (VPE) AND METALORGANIC CHEICAL VAPOR DEPOSITION (MOCVD) INTO ONE TECHNIQUE TO FABRICATE SUPERIOR INGAASP/INP DETECTORS, LASERS AND LEDS. THE HYDRIDE VPE TECHNIQUES IS A PROVEN GROWTH TECHNIQUE FOR INGAAS DETECTORS AND 1300 NM INGAAS LASERS AND LEDS. HOWEVER, THE EQUIPMENT IS USUALLY BUILT ON A "LABORATORY" BASIS AND HAS NOT ...

N/A

A NOVEL DEVICE IS PROPOSED FOR DETERMINATION OF THE SORPTION OF THE SIMULANTS AND THE CHEMICAL AGENTS BY THE PROTECTIVE OVERGARMENTS. A NOVEL CLASS OF SIMULANT-SENSITIVE COMPOSITIONS ARE USED IN THE DEVICE. THE SORPTION, THE ACTIVATION ENERGY OF SORPTION AND THE PROTECTION TIME OF THE OVERGARMENTS CAN BE DETERMINED IN THE FIELD. THE DEVICE DOES NOT REQUIRE EXPENSIVE AND BULKY ANALYTICAL EQUIPMENT. ...

N/A

WE PROPOSE TO DEVELOP A LARGE-SIZE (>1CM DIAMETER) INDIUM GALLIUM ARSENIDE PHOTODETECTOR WITH HIGH QUANTUM EFFICIENCY (>70%) OUT TO 2.1UM FOR FIBER OPTICS, EYESAFE RANGEFINDING, LIDAR AND LASER SEEKING. THESE DEVICES WILL HAVE LOW DARK CURRENTS FOR HIGH 300 DEG K SENSITIVITY (D* (12)CM (HZ)(1/2/W) AND HAVE SPECIAL DEVICE STRUCTURES FOR RISE/FALL TIMES NEAR 10 NANOSECONDS. EPITAXX IS UNIQUELY QUALI ...

THE NEED EXISTS FOR AN INTERFACE BETWEEN EXISTING TACTICAL RECORD TRAFFIC NETWORKS AND A PROPOSED WIDE-AREA TACTICAL PACKET SWITCHING NETWORK (TPN). THESE RECORD TRAFFIC NETWORKS INCLUDE THE AN/TYC-39 MESSAGE SWITCH (MS) AND THE MOBILE TACTICAL COMMUNICATIONS CENTER (MTCC). THE TPN IS TO BE PART OF THE MOBILE SUBSCRIBER EQUIPMENT (MSE), AND IS ASSUMED TO INTERFACE AND SHARE PROTOCOLS WITH THE DEFE ...

THIS PROGRAM WILL DEVELOP AN EFFICIENT MILLIMETER WAVEGUIDE AND MICROSTRIP INTEGRATION FOR THE 75 GHZ TO 110 GHZ BAND. THIS INTEGRATION WILL PROVIDE A TRANSITION SUITABLE TO INTERFACE WITH SEMICONDUCTORS. THE WAVEGUIDE AND MICROSTRIP INTEGRATION WILL BE INCORPORATED INTO A SOLID STATE NOISE GENERATOR. FREQUENCY OF THE END PRODUCT NOISE GENERATOR WILL INCLUDE THE 94 GHZ POINT.

PRESENTLY DIATOMACIOUS EARTH/FULLER'S EARTH ARE COMMONLY USED FOR DECONTAMINATION OF C.W.A., BUT THE CAPACITY OF THESE SORBENTS ARE ONLY LIMITED TO 25% OF THE SOLID'S WEIGHT. THIS EFFORT IS TO DEVELOP A REACTIVE SORBENT WHICH WILL CHEMICALLY (OR CATALYTICALLY) DESTROY THE C.W.A. WE HAVE CHOSEN HIGH SURFACE AREA INEXPENSIVE POROUS SILICA AS THE STARTING SORBENT. POROUS SILICA WILL BE SILANIZED BY V ...

THE PROGRAM DEFINES THE REQUIREMENTS FOR A SYSTEM SUPERVISORY CONTROL FUNCTION FOR ESM AND EW PLATFORMS, APPLICABLE TO THE US ARMY QUICK FIX SYSTEM. THE PROJECT INCORPORATES ARTIFICIAL INTELLIGENCE/EXPERT SYSTEM TECHNIQUES TO STRUCTURE THE DESIGN ARCHITECTURE AND CONDUCT THE KNOWLEDGE ENGINEERING NECESSARY TO DEFINE THE CONTROL STRUCTURE (INTERFERENCE ENGINE) AND THE KNOWLEDGE DATA BASE. THE EFFOR ...

A REQUIREMENT EXISTS TO PROVIDE OCULAR PROTECTION TO TROOPS AT RISK FROM LASER ENERGY EXPOSURE AND BALLISTIC FRAGEMENTS WHILE MAINTAINING ESSENTIAL VISUAL PERFORMANCE. OPTICAL FILTERS BASED ON HOLOGRAPHIC MIRRORS OR THIN FILM INTERFERENCE FILTERS ARE EFFECTIVE IN BLOCKING LASER BEAMS BUT ARE FRAGILE AND ARE SUBJECT TO DEGRADATION FROM AMBIENT MOISTURE. THIS LABORATORY PROPOSES TO MAKE THIN FILM IN ...
