Abstract:Xenotran corporation proposes to develop a new antenna system employing an optical true-time-delay steering technique that will be suitable for Army radar. The antenna system will be based on the optical commutator, a device that is capable of switching fiber optic delay lines in an ordered… more
Abstract:This proposal describes a novel flat-panel display using light-emitting-diodes (LEDs) as light sources. A side-lighting scheme is proposed to significantly reduce the number of LEDs from that required in a conventional LED matrix display. Channel waveguides and specially designed light switches… more

Abstract:The primary problem in organ transplantation today is the shortage of human donors. A proposed soluuse of pigs, but the risk of rejection is currently too great. The ultimate goal for transplant recispecific immune tolerance. They would then accept their grafts as "self' without immune suppression… more
Abstract:This program will provide meter class CERAFORM (TM) Silicon Carbide mirrors with an areal density of < 2 kg/mm2 for use in space based laser and surveillance systems. Providing larger, stiffer structures, CERAFORM (TM) SiC provides optical, structural and thermal properties which exceed that of the… more
Abstract:The development of a multi-channel GPS satellite signal simulator incorporating hypersonic re-entry effects is being proposed. The Phase 1 effort will focus on feasibility issues, Phase 2 hardware design issues, and a limited laboratory demonstrate of the concept using existing hardware. A GPS… more
Abstract:Although x-ray photoelectron spectroscopy (CPS) is an extremely valuable analytical tool for material characterization in semiconductor manufacturing, its use is limited by the currently available spatial resolution. The economical fabrication of ULSI circuits depends on in-situ non-destructive… more
Abstract:The project will research a new generation of optic for focusing cold neutrons using tapered capillary optics. The success of the program will result in neutron beam probes with unprecedented spatial resolution and detection limits for small sample volumes. The individuals involved are the world… more
Abstract:Polycapillary x-ray monolithic optics have the potential to be one of the best methods for controlling x-ray beams across a broad energy spectrum because of their efficiency, size, and applicability to a variety of technologies. Widespread use of polycapillary optics is currently impeded because… 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.
