Abstract:A novel hearing aid system based on advanced digital signal processing and radio transceivertechnology will be developed. Three parallel developments prove feasibility; 1) an ear module whichperforms implication and digitization of the acoustic environment; 2) a bi-directional digital radio… more
Abstract:The applicant firm proposes to use their unique and patented powder metallurgy technology to produce FACT parts with increased reliability and reduced weight, and at lower cost than other methods. It will use new and innovatie power metallurgy equipment and methods that can be automated to give fast… more
Abstract:A number of imaging and target identification admit a generalized tomographic formulation where the object to be imaged (identified) is multi-dimensional and the sensor data are one-dimensional generalized projections of this object. The goal of the proposed research is to formulate, develop and… more
Abstract:As an alternative to holographic laser radar, AMPS will develop a 3-D imaging concept that collects far-field intensity speckle patterns. This kind of measurement greatly relaxes the tolerances on vibration and coherence length. However, phase retrieval will be required to retrieve a 3-D image.… more
Abstract:A key component in the Alkali Metal Thermal to Electric Converter (AMTEC) is the electrode that is generally sputter deposited on the beta"-alumina solid electrolyte (BASE). Electrode deposition, as it is now practiced however, is a random process that covers active sites on the BASE and places many… more
Abstract:Advanced Photonic Technologies (APT), a Uniphase business unit, proposes to develop a low cost, compact, high power (3W cw) visible laser system emitting at 630 + 3 nm for both military and medical applications. This unique diode laser based system addresses an immediate and acute need for advanced… more
Abstract:The Oblique Detonation Wave Hypervelocity Scramjet(ODW Hy-Scram) Engine is applicable to hypersonic flight vehicles that require high Mach Scramjet operation. This project will implement a unique new analysis capability to analyze and assess a novel propulsion device that could greatly enhance… more
Abstract:This proposal describes an innovative Ultra-Low NOx annular swirl combustor concept for aircraft gas turbine engines. The concept is based on previously demonstrated means for creating high mixing rate regions in free shear flows by manipulating existing vorticity to create multiple discrete… more
Abstract:The Oblique Detonation Wave Hypervelocity Scramjet (ODW Hy-Scram) Engine is applicable to hypersonic flight vehicles that require high Mach Scramjet operation. This project will implement a unique new analysis capability to analyze and assess a novel propulsion device that could greatly enhance… more
Abstract:MONOLITHIC INTEGRATION OF SILICON AVALANCHE PHOTODIODE (APD) ARRAYS WITH THEIR ASSOCIATED ELECTRONICS IS BEING INVESTIGATED. THE PHOTODIODE ELEMENTS ARE BASED ON THE STATE-OF-THE-ART PROCESS WHICH ACHIEVES UNIFORM BULK BREAKDOWN BY USING NEUTRON TRANSMUTATION DOPED SILICON AND A "BEVELED JUNCTION"… more
Abstract:TO MEET EXISTING AND FUTURE CASTING MANUFACTURING NEEDS, THE DEVELOPMENT OF AN AUTOMATED RAPID METROLOGY (ARM) CAPABILITY FOR INVESTMENT CASTING LAYOUT IS BEING INVESTIGATED. THE APPROACH IS BASED ON THE EXTRACTION OF DIMENSIONAL INFORMATION FROM COMPUTED TOMOGRAPHY (CT) IMAGES OF A PART. A KEY… 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.
