U.S. production of Halons will decrease from 28 million lbs in 1988 to zero in 1995 to meet the U.S. commitments to the Montreal Protocol. A major use of Halon 1301 is as a fire suppression flooding agent. The use of fine water mists from two-fluid atomizing nozzles is proposed as a replacement for Halon 1301 fire suppression systems, especially for Class B fuel fires. The optimum droplet size and ...

We propose to demonstrate the feasibility of fabricating a phototransistor using the A1xGa1-xN material system. The proposed phototransitor is based on a GaN-A1xGa1-xN heterojunction which exhibits a 2-D electron gas conduction when a bias is applied on the source-drain terminals. The device is maintained in a nominally OFF state by applying a reverse bias voltage on the gate terminal. With optica ...

There is an increasing need in many military systems to have solid state microwave devices with higher power capability, higher reliability, and higher operating temperatures. These devices would be important for airborne radar systems, electronic warfare and countermeasure systems, and airborne and space-based communications systems. While conventional semiconductor materials such as SI and GaAs ...

The proposal is for an engineering design, including detailed shop drawings, of a cryostat for the condensation of solid hydrogen from the vapor phase, for storage with a heat leak of less than 10-4 watts/grams of hydrogen, and with controlled expulsion to a combustion chamber at greater than atmospheric pressure. The cryostat uses liquid helium as a coolant, and has a transparent freezing chamber ...

DATA FUSION CORPORATION PROPOSES THE PHASE I INVESTIGATION INTO THE MATHEMATICAL ISSUES INVOLVED IN THE DEVELOPMENT OF AN ANALYTICAL MODEL FOR THE MANAGEMENT OF SENSOR RESOURCES IN TACTICAL AIRCRAFT. THIS MODEL WILL INCORPORATE THE ANALYTIC HIERARCHY PROCESS (AH), A MATRIX EIGENVALUE-EIGENVECTOR METHOD FOR FORMULATING A SCALE OF ABSOLUTE PRIORITIES FOR PAIR-WISE RELATIVE PRIORITIES AMONG POTENTIAL ...

THE PROPOSED WORK AIMS TO DEVELOP OPTOELECTRONIC IMAGE PROCESSING DEVICES THAT INTEGRATE PHOTODETECTORS AND LIGHT MODULATORS INTO LARGE ARRAYS OF "SMART" PIXELS. THESE DEVICES EXPLOIT A HYBRID OPTOELECTRONIC TECHNOLOGY THAT PLACES FAST FERROELECTRIC LIQUID CRYSTAL (FLC) LIGHT MODULATORS DIRECTLY ATOP VERSATILE SILICON VLSI CIRCUITRY. THE DEVICES NOW PROPOSED WILL INCORPORATE MULTIPLE PHOTODETECTOR ...
