Abstract:THIS PHASE I PROJECT WILL DEVELOP A DETECTOR TECHNOLOGY FOR TRACKING PARTICLES CLOSE TO THE BEAM PIPE IN NEW GENERATION ACCELERATOR EXPERIMENTS. HIGH SPATIAL RESOLUTION, HIGH SPEED DATA READOUT, COMPACT SIZE, LOW POWER, AND RADIATION HARDNESS WILL BE ACHIEVED BY INCORPORATING A HIGH RESISTIVITY,… more
Abstract:THIS RESEARCH WILL DEVELOP A PORT DIGITAL IMAGER (PDI). THE PDI IS A MONOLITHIC, SOLID-STATE, DETECTOR ARRAY SUBSTITUTE FOR PORT FILM. BECAUSE THE SOLID-STATE ELECTRONICS DIGITIZE THE IMAGE, IMAGING SOFTWARE CAN BE USED IN CONJUNCTION WITH THE PDI TO IMMEDIATELY ENHANCE THE IMAGE CONTRAST. AN… more
Abstract:THIS PROPOSAL DESCRIBES AN INNOVATIVE AND PROPRIETARY MULTIPLE DETECTOR FOCAL PLANE ASSEMBLY (FPA) DESIGNED TO BE USED FOR HIGH RESOLUTION 3 DIMENSIONAL IMAGING (STARING) UNDERWATER LASER RADAR. THIS FPA DESIGN HAS THE FOLLOWING CHARACTERISTICS: CAN BE USED TO DETERMINE THE TIME-OF-ARRIVAL OF A… more
Abstract:Phase I will develop an advanced photocathode for high quantum efficiency, photon-counting sensitivity of 1.06 microsecond, Nd:YAG laser pulses. As far as maximum ladar range is concerned the proposed photocathode is equivalent to an increase of a factor of 15 in laser power. The photocathode is… more
Abstract:Phase I will develop a breakthrough in a Infrared (IR) detector, called the Super Sensitive Solid-State Infrared Detector because it: does not require indium bumping readout technology; can detect individual IR photons between 2 and 24 micrometers; is insensitive to gamma rays; has very low dark… more
Abstract:CURRENTLY, FOCAL PLANE ARRAY (FPA) SENSOR TECHNOLOGY REQUIRES READING OUT AND DIGITIZING EACH AND EVERY PIXEL ON THE FPA. IN ADDITION, ALL DATA PROCESSING IS PERFORMED ON A OFF-SENSOR DIGITAL COMPUTER. TO UTILIZE HUMAN-LIKE VISION IN LARGE-STARING-ARRAY HIGH-SPEED ACQUISITION AND TRACKING SENSORS,… more
Abstract:Metacognitive skills that involve the monitoring and control of cognitive skills like problem solving develop in expert executives and appear to lead to great improvement in the problem solving process. We propose to study the topic of metacognition to construct a conceptual model that has three… more
Abstract:THE FRONT END PREPROCESSOR FOR HUMAN VISION IS THE RETINA. BY PARALLEL EDGE PROCESSING, IT TRANSFERS TO THE BRAIN, IN REAL-TIME, THE ESSENTIAL CHARACTERISTICS OF THE SCENE BEING VIEWED. THE BRAIN THEN INTERPRETS THE IMAGE OUTLINE AND INITIATES BEHAVIORS. RESEARCHERS ARE DEVELOPING A VERY… more
Abstract:The U.S. Navy has a need for improving the defense of their ships and components through high risk/payoff technologies. Self defense can be greatly improved by using measures to control the electromagnetic signatures of Navy platforms. There has yet to be developed, a truly adaptive, multi-spectral… more
Abstract:ELECTRO-OPTIC MATERIALS CONSISTING OF RANDOM DISPERSION OF NEMATIC LIQUID-CRYSTAL MICRODROPLETS EMBEDDED IN AN ISOTROPIC TRANSPARENT POLYMERIC MEDIA (OR POLYMER DISPERSED LIQUID CRYSTALS (PDLC)) WERE DEVELOPED AT ADVANCED SURFACE TECHNOLOGY, INC. (AST) FOR USE IN OPTICAL AND ELECTRO-OPTICAL DEVICES.… more
Abstract:The use of biodegradable polymers for vascular reconstruction has two major advantages: the elimination of chronic foreign body reaction and the regeneration of arterial tissues including a nonthrombogenic pseudointima layer. However, it is well-known that the healing of human vascular tissues is… more
Abstract:This project describes the use radio frequency (RF) plasma induced polymerization for the preparation of new ion exchange support media for High Performance Liquid Chromatography (HPLC) separation of biopolymers. Silica and alumina supports will be uniformly coated with thin layers of polymerizable… more
Abstract:Increasing Navy use of embedded computer systems results in stringent requirements for real-time performance, reliability, and cost. Computer systems are critical embedded components of Naval warfare systems. The demands on embedded computer systems are increasing in terms of information processing… more
Abstract:THIS RESEARCH WILL EXECUTE AN INDEPTH STUDY OF THE BASIC FEATURES OF EMBEDDED SYSTEM AND PLANT PROCESS SOFTWARE, INCLUDING ITS INTERACTIONS WITH THE HARDWARE SYSTEMS THAT IT IS INTENDED TO CONTROL AND REGULATE. THE PURPOSE OF SUCH A STUDY WILL BE TO IDENTIFY THE PROCEDURES AND ANALYTICAL TECHNIQUES,… more
Abstract:THE OBJECTIVE OF THIS SBIR EFFORT IS TO DEVELOPE AN IR SCRENE PROJECTOR BASED UPON IR LASER DIODES WHICH CAN BE USED IN HWIL SIMULATIONS TO TEST MISSILE SYSTEMS. THE GOAL OF THE PHASE I EFFORT IS TO DEVELOPE A SINGLE CHANNEL LASER DIODE IR PROJECTION SYSTEM TO DEMONSTRATE THE PERFORMANCE… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
