Abstract:The overall technical objective of the proposed Phase II NASA program is to demonstrate the ability of the WaMM?-based static vapor feed electrolyzer to generate enough low moisture content oxygen to support the life of 5 astronauts (9.0 lbs/day). To achieve this, the stack must be designed for… more
Abstract:The power demands for a wide variety of advanced battlefield equipment can range from high-energy for long-term operation to high-rate pulse power. A major drawback of current power storage technologies for these applications is their inability to meet the demands of both high-energy and high-power… more
Abstract:GVD proposed to develop high performance, VOC-free and PFOA-free, non-stick mold release coating based on its novel PTFE (Polytetraflouroethylene) fluoropolymer technology. Most commercial mold release agents make use of organic solvents and vaporize during drying, creating a significant air quality… more
Abstract:Hstar proposes a mobile, advanced, agile, adaptable handling (A3-Hand) system for shipboard mission payload handling. On the LCS seaframes, A3-Hand"s ability to remotely load, unload and transport a wide variety of payloads in and around ISO containers and mission vehicles will immediately… more
Abstract:Traditional concepts of neural-machine interface use brain signals as: control inputs; to assess neurocognitive states for modification of information delivery to improve human performance; to guide selection of image sets. We propose a revolutionary concept of interfacing Electrical… more
Abstract:This STTR Phase II Proposal addresses the need for a low cost acoustic transmitter that combines a power amplifier, control-circuitry and an innovative transducer assembly, all at a low cost. Our approach is to use a cylindrical modal vector projector transducer which becomes part of the housing 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.
