Abstract:Many long term wheelchair users develop back pain or spinal and pelvic deformities, which are in part due to the rounded spinal posture promoted by the sling upholstery in the standard wheelchair. Two back support systems which connect to the vertical upright frame members of a standard wheelchair… more
Abstract:This project addresses the need for information systems for children and adults with disabilities. People with mobility and visual impairments. For example, wheelchair users desire to experience outdoor trails just as much as everyone else. Existing definitions of accessibility for building access… more
Abstract:BioTechnical Communications is proposing to develop a prototype for healthcare programming targeted to African-Americans, and to broadcast on Black Entertainment Television (BET), a targeted cable television network. BioTechnical Communications will be responsible for the accuracy of the technical… more
Abstract:THE LAST THREE YEARS HAVE SEEN A DRAMATIC INCREASE IN THE NUMBER OF COMPANIES PROCESSING POST-CONSUMER PLASTICS FROM PRODUCTS SUCH AS SOFT DRINK CONTAINERS, DETERGENT BOTTLES, MILK JUGS AND WATER BOTTLES. WHILE THIS HAS TO SOME EXTENT DIVERTED THESE MATERIALS FROM LANDFILLS, IT HAS CAUSED AN… more
Abstract:DIVERSION OF PLASTICS FROM LANDFILL TO RECYCLING CAN POTENTIALLY SAVE THE ENERGY EQUIVALENT OF 60 MILLION BARRELS OF OIL ANNUALLY AND REDUCE LANDFILL VOLUME REQUIRMENTS BY UP TO 20%. THE U.S. ENVIRONMENTAL PROTECTION AGENCY HAS RECOMMENDED THAT SOURCE REDUCTION, RECYCLING, VOLUME REDUCTION, AND… more
Abstract:EACH YEAR, AMERICANS DISPOSE OF AN ESTIMATED 29 BILLION POUNDS OF PLASTICS WHICH CONSUME UP TO 20% OF OUR NATION'S ANNUAL LANDFILL CAPACITY. RECENT ENVIRONMENTAL AND POLITICAL PRESSURES HAVE LED TO RAPID ESTABLISHMENT OF PLASTICS RECYCLING FACILITIES. LIMITED MARKETS FOR LOW QUALITY RECYCLED RESINS… more
Abstract:The recent advent in Personal Communications Networks, PCN, and Cellular communications has demanded low cost ferrite components for the RF front ends operating at 9GHz cellular and 1.8GHz GSM bands. The thrust of Personal communication is now being directed towards otherISM (instrumentation,… more
Abstract:An array suitable for millimeter wave radar application is proposed for development. The switch array will utilize planar field emitter array devices in the triode format. The main objective of Phase I is to demonstrate a new microwave and mm-wave switching device based on work performed by SSI… more
Abstract:In this Phase I effort, we propose to build and test a prototype of a revolutionary new concept for producing an electronically reconfigurable, low profile planar array antenna that is both lightweight and frequency agile. The reconfigurable antenna will be based on a diamond cold cathode switching… more
Abstract:Advances in signal processing and high speed digital image processing electronics make it feasible to implement a real-time image reconstruction algorithm in a digital FLIR system. Implementation of such an algorithm would result in increased spatial resolution on the order of two to three times and… more
Abstract:Pseudomorphic InGaAs with high InAs concentrations on GaAs substrates are currently in use in complementary-heterostructure FET (C-HFET) digital and MODFET MMW circuits. While their bandgaps enable them to detect 1300 and 1550 nm light, the projected detection efficiency (responsivity) is very low… more
Abstract:A promising new approach for high power solid-state sources will be demonstrated using spatial power combining grids. Present development of high power field effect transistor (FET) based solid-state sources at millimeter-wave frequencies is hampered by the limited power output of individual sources… more
Abstract:An epitaxial grown Germanium - channel Junction Field Effect Transistor (Ge-JFET) is proposed to provide the most efficient, low noise cryogenically cooled detectors operating at 2 - 4Â¿K. Precisioned engineered lattice and doping epitaxial growth will eliminate material defects to allow the… more
Abstract:To meet the future needs for increased capabilities in military as well as commercial space communications and radar applications, the W-Band (94 Ghz) frequency spectrum utilized. A critical issue has arisen in the development of the future W-band electronic systems technology: while InP-based… more
Abstract:THE FEASIBILITY OF A SIMPLE ATMOSPHERIC CARBON DIOXIDE (CO2) SENSOR FOR OCEANOGRAPHIC DEPLOYMENT WILL BE EXPLORED IN THIS PHASE I PROJECT. THREE BASIC STEPS ARE REQUIRED FOR SENSOR OPERATION: MEMBRANE EQUILIBRATION OF GASEOUS AND AQUEOUS CO2, CHEMICAL AMPLIFICATION OF THE CONCENTRATION OF THE… more
Abstract:The proposed Fiber-Optic Chemiluminescent Biosensor concept forms the basis for the development of a new class of light weight, small, low power, inexpensive robust, accurate and extremely sensitive sensors which can be applied to various analytical requirements within the aerospace biomedical,… 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.
