Abstract:Lanxide Corporation proposes to demonstrate the feasibility of utilizing the active brazing method to join a Nicalon TM fiber reinforced alumina matrix composite to structural alloys for applications i advanced turbine engines. The high temperature capability of the ceramic matrix composite allows… more
Abstract:We propose to develop an image fusion system to fuse images from an intensified TV and a thermal imaging system into a single image by using a pattern selective approach. Pattern selective approach is different from pixel averaging approach in its ability to retain the contrast of the important… more
Abstract:Efficient transmission in limited satellite bandwidth of imagery from near real-time reconnaissance is key to satisfying requirements for timely information. Standard compression may introduce degradations which significantly reduce the usefulness of imagery and communications errors may further… more
Abstract:The present E2C cockpit does not support the display of tactical information from the combat information center. The use of flat panel displays in the E2C cockpit will make it possible for pilot and copilot to observe tactical information in a form similar to that presented to the Naval Flight… more
Abstract:Nuclear, chemical and biological warfare weapons are the weapons of mass destruction (WMD). It will be desirable to develop a single detection system for monitoring proliferation of WMD based on monitoring of the particulates and trace chemicals in the air by air sampling. All the WMD and their… more
Abstract:Princeton Electronic Systems (PES), proposes to utilize the world's most advanced 3-dimensional charged particle trajectory simulation software available with Sarnoff to provide NASA with accurate performance simulations of mass spectrometers used for detection and measurement of planetary… more
Abstract:Using Combined Wavelength and Frequency Modulation Spectroscopy coupled with fiber coupled near infrared diode laser, nitrogen dioxide can be detected via its near infrared absorption band. Detection sensitivity in the parts-per-billion level can be achieved. The technique offers 5 decades of linear… more
Abstract:In this progam, Princeton Electronic Systems, Inc will develop a small, lightweight hand held gamma radiation detection and isotope identification system. The system will be intended for detection of clandestine movement of nuclear materials from nuclear facilities or storage areas and other places.… more
Abstract:ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH EFFICIENCY, MONOLITHICALLY INTERCONNECTED THIN SILICON SOLAR CELL ARRAY. THE ARRAY INCORPORATES AN INNOVATIVE TECHNIQUE TO ACHIEVE ELECTRICAL ISOLATION AND INTERCONNECTION OF THE ARRAY ELEMENTS. A MONOLITHICALLY INTERCONNECTED ARRAY TECHNOLOGY… more
Abstract:ASTROPOWER PROPOSES TO DEVELOP A NEW FRONT-ILLUMINATED, ALUMINUM GALLIUM PHOSPHIDE (AlGaP) BASED, CHARGE-COUPLED DEVICE (CCD), ULTRAVIOLET (UV) IMAGING ARRAY. THIS NOVEL ARRAY TECHNOLOGY HAS NEVER BEEN SUCCESSFULLY DEVELOPED. THREE NEW INNOVATIONS WILL BE NECESSARY TO ACOMPLISH THE AlGaP CCD. THESE… more
Abstract:A NOVEL SILICON DEPOSITION PROCESS CAPABLE OF DEPOSITING HIGH QUALITY THIN-FILM SILICON LAYERS ON LOW COST SUPPORTING SUBSTRATES WILL BE INVESTIGATED IN PHASE I. THE SUBSTRATE WILL INCLUDE A REFLECTOR FOR LIGHT TRAPPING. THE PLANNED DEPOSITION PROCESS WILL ALLOW THE FORMATION OF SILICON LAYERS 20… more
Abstract:INVESTIGATORS ARE DEVELOPING MONOLITHICALLY INTEGRATED BICOLOR EDGE EMITTER-DETECTOR PAIRS FOR WAVELENGTH-DIVISION MULTIPLEXING IN FIBER OPTIC COMMUNICATIONS. THIS DEVICE UTILIZES LATERALLY GRADED A1XGA1-XAS LAYERS FORMED BY LIQUID PHASE EPITAXIAL DEPOSITION ONTO A CONTINUOUSLY MOVING SUBSTRATE. … more
Abstract:THE SOLAR CELL APPLICATION OF CRYSTALLINE SILICON THIN-FILM, PHOTOCOLTAIC (PV) TECHNOLOGIES IS CURRENTLY LIMITED BY THE HIGH COST OF THE SILICON RAW MATERIAL. THIS IS A RESULT OF THE CARBOTHERMAL REDUCTION METALLURGICAL PROCESS USED TO CREATE THE SEMICONDUCTOR-GRADE SILICON FROM SILICA. THERE IS A… more
Abstract:AstroPower proposes to develop intense, mass-producible, low-cost 4 to 5 micron light-emitting diodes (LED's) using liquid-phase heteroepitaxy of lattice-matched InAsSb on GaSb substrates. The brightest visible LEDs (Ultrabrights) currently available are being produced commercially by the liquid… more
Abstract:REDUCTION OF AUTOMOBILE WEIGHT IS AN IMPORTANT APPROACH TO REDUCING FUEL CONSUMPTION. MAGNESIUM ALLOYS WOULD OFFER THE POTENTIAL FOR SIGNIFICANT WEIGHT REDUCTIONS IF THEY WERE MORE READILY FORMED AND THEIR STIFFNESS COULD BE INCREASED. HIGH STRAIN RATE SUPERPLASTIC FORMING OFFERS A COST EFFECTIVE… more
Abstract:VOLATILE ORGANIC COMPOUND (VOC) EFFLUENT STREAMS ARE A SERIOUS AIR POLLUTION PROBLEM. CONTROL TECHNOLOGIES FOR VOCS HAVE BEEN OXIDATION OR CARBON ABSORPTION BUT RECENTLY MEMRANES HAVE SHOWN EFFECTIVENESS. PRESENT MEMBRANE PROCESSES WORK BY PREFERENTIALLY PASSING VOCS (VERSUS AIR) THROUGH THE… 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.
