A HIGH-ACCURACY TEMPERATURE SENSOR--WITH IMMUNITY TO EMI--IS PROPOSED AS AN OCEAN TEMPERATURE MONITOR. THE SENSOR CONSISTS OF A BROADBAND LIGHT SOURCE COUPLED INTO AN OPTICAL FIBER WHICH TRANSMITS THIS BROADBAND SPECTRUM TO THE REMOTE SENSOR ELEMENT. THE SENSOR ELEMENT IS A VARIABLE GAP FABRY-PEROT CAVITY WHICH MODULATES THE REFLECTED SPECTRUM ACCORDING TO GAP DIMENSION. THE REFLECTED SPECTRUM IS ...

WITH THE RECENT, RAPID ACCELERATION IN THE GROWTH OF FIBER OPTIC TRANSMISSION SYSTEMS, IT SEEMS LOGICAL THAT ALL-OPTICAL SENSORS WILL BE THE NEXT GENERATION OF SENSORS -NOT JUST FOR TEMPERATURE AND PRESSURE BUT FOR A VARIETY OF PARAMETERS, INCLUDING STRESS, DISPLACEMENT, LIQUID LEVEL, ETC. TO DEMONSTRATE THE OPTICAL SENSOR CONCEPT, A TEMPERATURE SENSOR WILL BE DESIGNED AND FABRICATED FOR APPLICATI ...

A BROAD-RANGE PRESSURE SENSOR CONCEPT IMMUNE TO HARSH ENVI- RONMENTS AND EXTREME TEMPERATURES IS REQUIRED FOR RESEARCH MEASUREMENTS IN WIND-TUNNEL TESTING. THE PRO- POSED SENSOR--FABRICATED AS INTEGRAL TER- MINUS OF A SINGLE MULTIMODE FIBER OPTIC CABLE -- IS ESSEN- TIALLY ALL GLASS AND HENCE IMMUNE TO HIGH TEMPERATURE A WELL AS ELECTROMAGNETIC INTERFERENCE. THE RESULTS OF A PHASE I STUDY AS DELINE ...

A novel photoreceiver is proposed based upon the optical sensitivity , gain and impedance transformation properties of an optoelectronic thyristor and HFET integrated circuit. The thyristor is implemented as a vertical cavity device and is compatible withcomplementary HFET digital/analog electronics or complementary bipolar analog/digital gates in a monolithic technology. The thyristor is designe ...

76293S With network bandwidth increasing more rapidly than processor speed for the past two decades, a serious performance problem exists for the transport, storage, and retrieval of large amounts of scientific data. This project will identify current performance bottlenecks, and develop a high-performance, processing and forwarding engine-hardware architecture that will handle data rates of 10 ...

Open Tech, Inc. seeks to develop a Virtual Environment Windowing Library (VEWL) that will provide users with an intuitive user interface and device independent interaction methods. The interface will allow users in a virtual environment to run applications and configure the environment using the same windows and controls that they are used to using on desktop systems. The software will provide for ...

Open Tech will create an interactive multi-user collaboration product for immersive and desktop scientific visualization. This product will leverage our Virtual Reality Windowing Library to enable an easy to use collaboration interface that includes user lists, radars, maps, avatars, white boards, and virtual presentations. The product will also contain a software framework that enables developers ...

DESCRIPTION (provided by applicant): The success of research in the post-genomic era is being compromised by the inability of researchers to find and use the vast genomic and bioinformatic resources available to them. Though hundreds of resources are freely available and easily accessible on the web, it is a Herculean task for biomedical researchers to find the relevant resource for their needs. I ...

THE IDENTIFICATION AND MANAGEMENT OF HAZARDOUS MATERIALS THROUGHOUT THE ACQUISITION LIFE CYCLE OF LARGE-SCALE SYSTEMS ARE ESSENTIAL FOR THE EFFECTIVE CONTROL OF TOTAL LIFE CYCLE COSTS. THE EXPLICIT INCLUSION OF HEALTH, SAFETY AND ENVIRONMENTAL FACTORS, ALONG WITH OTHER SUPPORTABILITY CONSIDERATIONS, WILL ENHANCE THE SYSTEM PERFORMANCE. THE PROPOSED RESEARCH WILL EXPLORE ALTERNATIVE APPROACHES FOR ...
