High speed, low cost optical self routing optical crossbar switches with gigabit data rates are key components in optical communication and routing systems. We propose to fabricate and study a monolithically integrated optical crossbar switch which will be inexpensive and high performance. This integrated switch utilizes thin film emitters and detectors integrated directly onto a host integrated c ...

THIS PROJECT DEVELOPS AND FIELD TESTS A PROTOTYPE SOFTWARE/HARDWARE ASSESSMENT PACKAGE TO SUPPORT ASSISTIVE TECHNOLOGY ASSESSMENT PERSONNEL RESPONSIBLE FOR SELECTION OF APPROPRIATE CONTROL INTERFACE DEVICES FOR PERSONS WHO HAVE DIFFICULTY INTERACTING WITH THEIR ENVIRONMENT. THIS POPULATION INCLUDES INDIVIDUALS WITH LEARNING, INTELLECTUAL, OR PHYSICAL DISABILITIES; VERY YOUNG PERSONS; AND/OR ELDERL ...

Sports Center Unlimited will be a simulated sports/leisure activity exploration program for youths with physical disabilities. The Phase I prototype will run on a Macintosh using QuickTime multi-media with sound, color, video, animation, and user interaction. As one of many animated characters, each with differing disabilities, the user explores the Sports Center Unlimited with the assistance of a ...

The goal is to develop a knowledge-based expert management system to deliver cost-effective quality medical care. This system will allow health care providers to plan and allocate services within the existing budgeting and economic constraints. The methodology consists of 1) building an integrated database of clinical and management information, 2) designing the knowledge representation used in th ...

AT THE PRESENT TIME, ALL MATURITY SORTING OF FRUITS AND VEGETABLES, SUCH AS APPLES, PEACHES ANDTOMATOES, IS ACCOMPLISHED EITHER BY HAND, BY COLOR OR BY THE USE OF THE MAGNESS-TAYLOR . EACH OF THESE TECHNIQUES HAVE MAJOR DISADVANTAGES IN THE HIGH-SPEED MATURITY GRADING OF FRUITS AND VEGETABLES. THE ANNUAL VALUE OF THE THREE NAMED FOOD CROPS ALONE IS IN EXCESS OF ONE BILLION DOLLARS, AND THE OPPORTU ...

Development of novel boronated compounds and use of epithermal neutrons has now generated much interest in 10B-boron capture neutron therapy of different tumors. However, no suitable methods exist that allow investigation of their pharmacokinetics in human subjects or in vivo measurement of the ratio of intracellu- lar/extracellular 10B at the time of irradiation. A new approach based on the use o ...

THE RESULT OF THIS PHASE I EFFORT WILL BE A DETAILED PLAN TO SIGNIFICANTLY INCREASE THE SPEED AND, HENCE, THE INTERACTIVITY OF ANALYZE, AN ALREADY USEFUL MEDICAL IMAGE ANALYSIS SYSTEM. ANALYZE IS A SOFTWARE SYSTEM FOR THE ANALYSIS OF MEDICAL IMAGES, DEVELOPED AT MAYO FOUNDATION'S BIOTECHNOLOGY COMPUTER RESOURCE. INCREASED PERFORMANCE WILL BE ACHIEVED BY IMPLEMENTING SELECTED PORTIONS OF ANALYZE ON ...

X-ray computed tomography (CT) is widely used in defense, aerospace, and industrial applications. CT provides flaw detection, density measurement, accurate dimensions, morphology, assembly verification, material property analysis, and other vauable information. However, a major limitation of CT has been the inspection time required for 100% coverage of an object, since a single slice through the o ...

We propose to develop in this Phase I SBIR a technique to produce high-energy, multi-aspect radiographic images in near real-time, using a conventional real time radiography (RTR) system. This technique, stereo-pair imaging, will allow three-dimensional analysis of RTR images by producing two views, at different angles, of the object being inspected. The separate views will be generated by taking ...
