The ultimate purpose of the proposed R&D is to develop and demonstrate an innovative software development environment which supports the engineering, analysis, development, test, maintenance, and reuse of software for embedded, heterogeneous, real-time systems. The proposed approach is innovative in two respects: (1) it is based on the integration of two best-of-breed environments, ObjecTime/ROOM ...

USING TECHNOLOGY NOW IN EXISTENCE AND NOW BEING DEVELOPED IT IS POSSIBLE TO BUILD A HIGH RELIABILITY, CRYOGENIC OXYGEN REFRIGERATOR. THE TEMPERATURE RANGE IN WHICH THE REFRIGERATOR WOULD FUNCTION WOULD BE CONTROLLABLE BETWEEN 70 AND 140 KELVIN. THE BASIS FOR THIS REFRIGERATION CYCLE WOULD BE CERAMIC ELECTROLYTE TECHNOLOGY BY WHICH OXYGEN CAN BE COMPRESSED USING AN ELECTRIC POTENTIAL ACROSS THE CER ...

THIS PROPOSAL IS PREPARED IN DIRECT RESPONSE TO THE NRC'S SOLICITATION FOR AN IMPROVED DEVICE TO MEASURE AIR MOVEMENT FOR PERSONNEL RADIATION PROTECTION AND HEALTH PHYSICS APPLICATIONS IN NUCLEAR FACILITIES. THE PURPOSE OF THE NEW DEVICE IS TO PROPERLY LOCATE AIR SAMPLERS SO THAT THE AIR SAMPLED IS REPRESENTATIVE OF THE AIR INHALED BY WORKERS. ALTHOUGH AIR FLOW RATE SENSORS SUCH AS ANEMOMETERS ARE ...

The proposed project will produce single-crystal boules of GaN that can be sliced and sold as high-quality substrates for the epitaxial growth of differently-doped GaN or of other lattice-matching crystals, or as wafers for use in optoelectronic and acoustooptic applications. The feasibility of GaN boules will be tested on a small scale: to produce cm3-sized crystals. The process will be scles up ...

Astralux, Inc. will develolp a seminconductor sensor sensitive to bacuum ultraviolet photons. For this, we shall synthesize a wide bandgap semiconductor capable of forming a built-in electric field that will separate the photogenerated electron-hole pairs and produce a photovoltage in response to the incident UV. This sensor should have no response to light in the visible spectrum. In this project ...

There is a market for a room temperature infrared detector as well as for a detection system which is radiation resistant and works at high temperatures and in reactive environments. Current infrared imaging technologies are too expensive and too bulky for these applications. We are proposing to develop an infrared and thermal detector based on a novel kind of light converter. The concept incorpor ...
