We propose a dratically new optoelectronic chip modules (OCMs) concepts to optically interconnect Si-based VLSI wafer-scale integrated circuits. Realizing the fact that system clock speed is three to five times higher than that ofprocessor speed, we propose to develop an optical clock signal distribution networks for wafer-scale interconnects. The architecture is to employ a superstrate Si/Ge wave ...

Materials Research Group, Inc. (MRG) proposes the process development of low-temperature fabrication processes for thin film silicon carbide (SiC) infrared (IR) emitter on flexible substrates for thermophotovoltaic (TPV) applications. Optimizing the emitter is critical to an effective TPV system. The outstanding thermal and chemical stability of SiC enable it to operate at high temperatures up to ...

Improved clutter suppression in Infrared Surveillance Sensors is acheived by reprocessing the data fields in the vicinity of detected Targets to distinquish between true Target responses and leak through Clutter responses that arise from clutter "Microgradients" hidden well below the primary clutter flucuations. The clutter "Microgradients" may exhibit rapid spatial changes in gradient properties; ...

We propose the use of our patented Low Temperature Arc Vapor Deposition (LTAVD) process to deposit protective coatings on composite structures to promote oxidation resistance, wear resistance and damage protection. We will demonstrate proof of concept and deliver representative test samples to the government. Present plans are to deposit coatings of titanium nitride onto composites and to experime ...

We propose the new architecture to attain the following tasks: a) Optimal and deadlock-free combination of global load balancing with dynamic task scheduling on a multiprocessor machine, yeilding busyness close to one for arbitrary algorithm; b) Optimal and deadlock-free fault tolerant execution with the minimum number of messages and no postponements of the underlying computations; and c) Assuran ...

COMPOSITE LAMINATES MAY IMPROVE AEROSPACE STRUCTURES, IF THE COMPOSITES DON'T DELAMINATE. DELAMINATIONS RESULT IN UNPREDICATBLE STRENGTH AND STIFFNESS REDUCTIONS AND ARE DIFFICULT TO DETECT. THIS PROJECT PLACES TRIAXIAL ARRAYS OF OPTICAL GLASS FIBER IN LAMINATES. WHEN DELAMINATION OCCURS, THE OPTICAL FIBERS BREAK AND THE DELAMINATION CAN BE DETECTED BY SIMPLE OPTICAL INSPECTION. THE FIBERS ALSO RE ...

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 ...

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 ...
