Abstract:During Phase I, we will develop the technology for a field use instrument to determine the residual stress, fatigue damage and remaining service life for aging metal structures. The technology will be based on a state-of -the-art wide-angle x-ray detector recently developed at ATMI. The life span… more
Abstract:GaN-based p-i-n photodiodes are in ideal choice for the Air Force's UV radiation measurements needs since these solid-state detectors are compact, light, and have low power consumption. However, current GaN photodiodes have much larger dark currents than expected. This Phase I program seeks to… more
Abstract:This SBIR project will determine the feasilibility of acoustic interference rejection techniques for a submarine acoustic intercept system. The signal processing techniques developed will permit the continuous tracking of active weapon sonars in the presence of interference from countermeasures and… more
Abstract:Piezoelectric ceramics in sensors have achieved substantial market penetration. These parts are used widely for heat and climate control, hydrophones, flow sensors, medical and industrial sensing and accelerometers but they have been unsuccessful in gaining significant use in actuators. It… more
Abstract:The goal of this program is to develop a low cost, flexible manufacturing method for the production of high temperature ceramic composites for rocket propulsion systems. The matrix materials selected for this program will be ZrC, HfC, and TaC. These-materials have good oxidation/corrosion and… more
Abstract:The objective of this proposal is to demonstrate the feasibility of vacuum micro-packaging for devices such as MEMS gyroscopes and accelerometers. Vacuum is critical for high Q-factor, surface-micromachined MEMS. Robust, low-cost solutions are needed for applications such as guided munitions and… more
Abstract:In today's military environment ships, systems, and equipment are being asked to perform at levels not thought possible a decade ago. The intent is to improve process operations and equipment reliability, availability, and maintainability without costly upgrades. Of course, these gains must be… 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.
