Abstract:65714 Electrical generators have to run at constant speed to generate electrical energy at a fixed frequency. This creates difficulties when the driving power source has variable speed, such as with a wind mill. This project will develop a converter that employs a field system that… more
Abstract:During typical wheelchair pushrim propulsion, significant forces must be applied by the wrist, arm and shoulder, despite the fact that they are not in optimum positions. Not surprisingly, pushrim wheelchair propulsion is associated with several common injuries. The most common are shoulder injuries… more
Abstract:DESCRIPTION: The purpose of this research is to provide persons who have
physical impairment and unintelligible speech with an access method for
assistive devices that (i) significantly reduces the physical fatigue
experienced during device access and, (2)… more
Abstract:FOURIER TRANSFORM INFRARED EMISSION SPECTROMETRY (EMISSION FTIR) HAS BEEN A STANDARD METHOD FOR CHEMICAL ANALYSIS. EXISTING EMISSION FTIR SPECTROMETER IS LARGE, HEAVY AND POWER INTENSIVE. THIS PROGRAM SEEKS TO DEVELOP A MINIATURE, SENSITIVE, ROBUST, LOW POWER AND LOW COST FIBER OPTIC EMISSION FTIR… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project is designed to build a prototype miniature fiber optic NOx sensor for the control of auto emissions. The proposed sensor is based upon a company invention on miniature chemilluminescence detector for gas chromatography. The prototype… more
Abstract:For this Phase I SBIR proposal, Space Photonics puts forth highly innovativesolutions for multi-access satellite clusters using our proposed miniature modularfree-space laser communications transceiver subsystem. By virtue of our uniquedevice and application specific designs, our laser cross-link… more
Abstract:An optoelectronic integrated circuit combines intersubband infrared and wide bandgap ultraviolet absorption in one pixel with an integrated output. Currently, QWIPs employ a doped multiquantum well structure sandwiched between n+ type contacts. Thequantum barrier limited dark current flow… more
Abstract:Not Available DoD plans to acquire new simulators for training warfighters to operate in hostile urban environments. These simulators need computer-controlled urban-oriented entities to interact with trainees realistically, taking into account: physical models of human movement and performance… more
Abstract:Not Available The proposed concept of advanced thermal barrier technology utilizes fullerenes and fullerene-based materials to create effective lightweight and environmentally safe thermal protection coatings on exterior aircraft structures exposed to high temperatures. Based on preliminary results… more
Abstract:Not Available The U.S. Army has a need for the development of new antenna materials technologies that will extend the band coverage and direction of arrival of communications, radar warning, and countermeasure antennas. This new materials technologies study should result in an extremely broad… 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.
