Abstract:Communications systems are hindered by inherent system limitations and also by physical attributes. For WCDMA systems three prominent issues are capacity, high latitude performance (for systems based on geosynchronous satellites), and Line Of Sight (LOS) performance. The MUOS system, based on… more
Abstract:Geost and the University of Arizona propose to develop a non-lethal weapon system based on dual-pulse femtosecond-nanosecond generation of dense plasma sparks in air at range. In this approach, the femtosecond laser pulse creates a dilute plasma filament, location of which is controlled through the… more
Abstract:The U. S. Navy is seeking novel survival rafts for Navy pilots that may have to ditch at sea. The technology currently utilized have inflated gas compartments, generally carbon dioxide, that provide the necessary buoyant forces to keep the raft and its pilot afloat. This foundational technology, (i… more
Abstract:Pacific Innovation proposes to develop an improved RF propagation and scattering simulation applicable to complex scattering and propagation environments that include specular and diffuse surface scattering, and volume attenuation, refraction, and scintillation. To properly model inherent… more

Abstract:The ultimate objective is to develop a suite of software tools and related databases that allow users to execute existing TPSs on multiple ATE benches, regardless of whether the original TPS was designed to work on that bench. To do this, the suite will include the Translator tool that translates… more
Abstract:Maritime surveillance of small boats is a key component to protecting U.S Navy fleet assets in both littoral and deep water environments. Detection and identification is complex due to the size and mobility of the threat in addition to highly variable environmental factors including sea state and… more
Abstract:A structural health monitoring / prognostic system for landing gear will be developed and demonstrated using load and other parameters as input data. Loads experienced by in-service landing gear assemblies will be measured by strain gaging and calibrating the landing gear"s attachment pins.… more
Abstract:As the Navy fleet ages there are many system components with small, cylindrical bore shapes with wear and/or corrosion damage which can not realistically be removed for repair. The current repair method most commonly used, brush electroplating, does not last long, requiring frequent repairs. The… more
Abstract:CEPEDA's Shipboard Cardboard Preprocessing System utilizes modular sensing and stripping sections that ensure all tape and plastic labels are removed from the input cardboard. An innovative sensor has been conceived and tested on the bench top that can accurately distinguish tape and labels on… more
Abstract:We propose to demonstrate the feasibility of using time domain terahertz measurements to locate, identify and image defects and material variations within advanced composite materials used in missile radomes. We will investigate the time and frequency domain transmission properties of radome… 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.
