A potential operation to remove material, achieve the desired… more
Abstract:Added capabilities for U.S. military ground, air, and sea vehicles have increased electrical power demands and the potential for extremely large fault currents. Fast and reliable means to limit fault currents and isolate faulted sections are required to meet these emerging power needs. We propose… more
Abstract:The targeting accuracy of mortar rounds is critically dependent on obtaining accurate gun barrel azimuth and elevation data to feed to the fire control system. Current barrel attitude determination is not sufficiently accurate and requires manual readouts. Creare proposes to build a sensor for the… more
Abstract:Navy ships need improved laundry dryers that use less energy and operate without air vents. Ventless dryers eliminate the need for very long exhaust ductwork and reduce fire hazards. We propose to develop a reliable, compact, tumbler-dryer that employs an innovative water separation process that is… more
Abstract:Advanced underwater vehicles (unmanned underwater vehicles (UUVs), torpedoes, etc.) are key to achieving long-term objectives for undersea force projection and surveillance. Existing battery-based power systems for these vehicles do not meet mission requirements due to low energy density,… more
Abstract:ABSTRACT: The performance of supersonic inlets, actuators, and scramjet isolators is limited by shock wave/boundary layer interactions (SBLIs). These interactions lead to flow separation, increased total pressure loss, and fluctuations that can cause excessive thermal or structural loading. … more
Abstract:DESCRIPTION (provided by applicant): Hearing loss is a leading public health concern, with about 17% of American adults reporting some degree of impairment. Of those, fewer than 20% seek help for their condition for a variety of reasons. To address this issue, the National Institue of Deafness 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.
