Abstract:The goal of this proposed multiphase SBIR program is to enhance the Marine Corps tactical receive capability by providing a small, light weight, low power and low cost device with built in step, scan, and search capabilities to aquire and process all standard military communications signals ranging… more
Abstract:The goal of this proposed multiphase SBIR program is to build and demonstrate Multiple Vehicle Cooperative Control Subsystem (MVCCS) for autonomous, optimal positioning of several Unmanned Ground Vehicle (UGVs) working together. By facilitating the ability of UGVs to share information and adaptively… more
Abstract:It is proposed to experimentally explore two active separation-control concepts aimed at stall alleviation and maximum-lift improvement on generic, vortex-dominated fighter configurations. The concepts comprise a delta wing incorporating transversely-hinged apex flaps oscillating in the pitch plane,… more
Abstract:THE OVERALL GOAL OF THIS RESEARCH PROJECT IS TO DEVELOP NEW EVACUATED TEST TUBES FOR BLOOD COLLECTION CONTAINING HIV NEUTRALIZATION AGENT(S) TO REDUCE AND/OR ELIMINATE THE RISK OF CONTRACTING HIV BY HEALTH CARE WORKERS HANDLING PATIENT SPECIMENS WITHOUT COMPROMISING TEST RESULTS. THE SPECIFIC GOAL… more
Abstract:The molecular cloning and the expression of the Salmonella typhi (ST) 36 kDal porin in Escherichia coli, the sequence analysis of its gene, the preparation of monoclonal antibodies against this antigen, and immunoblots and radioimmunoprecipitations assays of labeled ST whole cells have indicated… more
Abstract:THIS PROJECT ADDRESSES THE NATIONAL NEED TO DEVELOP AN EFFICIENT METHOD AND INSTRUMENT TO MONITOR AIR TOXICS IN GAS FLOWS. THE CURRENT SITUATION REQUIRES THE DETAILED CHARACTERIZATION OF TOXIC AIR EMISSIONS FROM FLUE GASES WHILE THE EXISTING MEANS LACK SELECTIVITY AND PERFORMANCE. NEW AND HIGH… more
Abstract:Profound increases in the ethnic composition of the United States have resulted in a growing demand for hearing test materials appropriate for children and adults who are not native English speakers. Auditory/visual word-identification materials are uniquely suited to this purpose since they may be… more
Abstract:THE PRINCIPAL OBJECTIVE IS THE COMMERCIAL DEVELOPMENT OF A VIRTUAL REALITY SIMULATOR TO ASSESS DRIVING PERFORMANCE IN PERSONS WITH VISUAL FIELD LOSS. THIS INTERACTIVE SIMULATOR WILL GIVE SUBJECTS THE SENSATION THAT THEY ARE DRIVING IN A VIRTUAL WORLD WITH THE USE OF WIDE- FIELD DRIVING SCENES,… more
Abstract:Vibrio cholerae vaccines which elicit antibodies against cholera toxin (CT) have been demonstrated to confer cross protection to human vaccines against strains of heat-labile toxin (LT) producing enterotoxigenic E. coli (ETEC). Vaccines were still vulnerable, however, to heat-stable toxin (ST)… more
Abstract:The problem with the current chimpanzee model for evaluating HIV prophylactics is both availability and cost of the animals. Similarly, the SIV model is limited since protection studies in primates illustrated that the immune protective epitopes of SIV envelope glycoprotein are structurally very… more
Abstract:LIGHT SCATTERING (LS) IS ONE OF THE MOST COMMON TECHNIQUES FOR POLYMER CHARACTERIZATION. THE LS INTENSITY AND ITS ANGULAR DISSYMMETRY ARE THE TWO EXPERIMENTAL RESULTS THAT GIVE THE POLYMER MOLECULAR WEIGHT (MW) AND MOLECULAR SIZE (RADIUS-OF-GYRATION RG) INFORMATION RESPECTIVELY. WHEN A MULTI-ANGLE… more
Abstract:THE PROCESSES AND EQUIPMENT FOR HANDLING SOLIDS AND SLURRIES ARE QUITE INEFFICIENT WHEN COMPARED WITH EQUIPMENT THAT HANDLES LIQUIDS AND GASES. THIS IS LARGELY BECAUSE DESIGNERS DO NOT CLEARLY UNDERSTAND THE BEHAVIOR OF GRANULAR SOLIDS AND SLURRIES SUCH AS COAL-WATER SLURRIES. IN PHASE I OF THIS… more
Abstract:IT HAS BEEN RECOGNIZED BY BOTH THE AIR FORCE AND NASA THAT SPACE DEBRIS IN THE GROWING HAZARD TO SPACE OPERATIONS. OF PARTICULAR IMPORTANCE ARE DEBRIS IN THE 0.1 - 10 CM SIZE RANGE. OVER THIS RANGE, DEBRIS DATABASES (AND CONSEQUENTLY DEBRIS MADELS) ARE DEFICIENT. ALSO, THESE PARTICILE SIZES ARE… more
Abstract:IT IS PROPOSED TO DEVELOP AN INNOVATIVE TARGETING/TRACKING LIDAR SYSTEM WHICH WILL HAVE THE CAPABILITY OF ACQUIRING, IMAGING AND TRACKING DESIGNED TARGETS AND BACKROUNDS. THE LIDAR SYSTEM WILL BE ABLE TO OPERATE OVER MULTIPLE WAVELENGTHS AND HAVE THE CAPABILITY FOR POLARIZATION ANALYSIS OF THE… more
Abstract:As the USAF works towards extending the performance envelope of its moder high performance aircraft and advanced re-entry vehicles, it is beginning to encounter multiple problems created by the presence of high temperature plasmas. The source of the plasma may vary from a jet or rocket engine plume… more
Abstract:This exploratory development is directed toward finding new methods of using artificially modified ionospheric regions for extending and enhancing communication (C3I) and surveillance (radar) capabilities. Specifically, the investigation, starting with a Phase I feasibility and planning effort and… 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.
