Abstract:The object of this effort is to employ VisiCom's considerable experience in reconfigurable logic engines, general computer hardware architecture, and software to show feasibility of combining core logic (mask programmable) microprocessor and FPGA devices. In order to optimize speed, VisiCom will… more
Abstract:Visidyne proposes an effort leading to improved tools for measuring the subsurface spatial structure and chemistry of highly turbid media such as mammalian tissue. The technology uses optical photon density waves from laser sources, intensity modulated at microwave frequencies to probe these media.… more
Abstract:Previous Doppler lidar statistical measurements of mechanical turbulence have only been successful in discerning moderate to strong wind field turbulence. This limitation is related to the transmitter pulse duration which is restricted by both the available laser technology and the range resolution… more
Abstract:Using newly available materials and component technologies, Visidyne proposes to demonstrate the feasibility of a novel monolithic sensor based on the photonic sensing of a magnetic field. The proposed sensor is capable of routine high sensitivity at bandwidths in excess of 500 kHz, and large… more
Abstract:We propose to critically evaluate by measurement, analysis, and an engineering study the potential for adaptation of Visidyne's intensity modulated diode laser technology to the construction of 1) a quasi-cw lidar suitable for UAV mounting and with sufficient sensitivity to remotely detect evaluated… more
Abstract:This proposal describes a computational model of human observers, DYTA(dynamic Target analysis), for dynamic target detection, depth and velocity estimation DYTA will be developed based on human perception knowledge as well as physics of moving vehicles. The computational model consists of two… more

Abstract:The use of computer modeling in the area of design optimizing has become practical due to recent advances in hardware and software technology. Several sophistcated software tools are avialable for three dimensional modeling and dynamic visual and numeric anaylsis of complex surfaces. This proposal… more
Abstract:THE GOAL OF THIS PROGRAM IS TO DEVELOP A TERABIT/SEC PHOTONIC INTERCONNECT NETWORK BASED ON MULTI-WAVELENGTH VERTICAL-CAVITY SURFACE-EMITTING LASER ARRAYS. WE WILL DEVELOP THE ARCHITECTURES, DESIGNS AND COMPONENTS FOR SUCH A SYSTEM. THIS SYSTEM WILL SOLVE THE PROBLEMS ASSOCIATED WITH THE LIMITED… more
Abstract:Existing automatic speech recognition (ASR) systems work well in quiet surroundings for small- and medium-sized vocabularies, but performance degrades rapidly in noisy environments. Achieving noise robustness is amust before ASR is widely deployed by the Air Force or becomes accepted in the… more
Abstract:Tanks of different models have unique acoustic signatures. These signatures can be used for detection and for identification. One approach is to analyze the signature in the spectral domain, using the Fourier transform, and comparing new sound samples with known templates. Problems arise when… more
Abstract:Vortec proposes to improve the IR transparency, thermal shock resistance, and processing of AlN through the exploitation of the unique properties of nanocrystalline materials. We will construct test windows consisting of nanocrystalline AlN where the grain sizes are on the order of about 100 nm. … more
Abstract:Vortec proposes to eliminate much of the cost originating from the post ceramic processing machining of single mode ferrules through the use of nanocrystalline sintering aids. Single mode ceramic ferrules made from micro particle size powders u Using a yttria-stabilized zirconia body composition,… more
Abstract:The need exists to generate high-quality electromagnetic planewave enviroments over large assets or extended volumes for testing avionics suites installed on full-size aircraft. Previously, these conditions were realized only be using farfield ranges or large compact range configurations. We… more
Abstract:The objectives of this project are to establish ballot ready specifications for the Standard Automatic Test System (SATS) Hardware Interface for Instrument, Power Supply, Switch Matrix, Receiver, Fixture, Pin Map, Cabling, and Secondary Connector Packaging. These interfaces will be based upon an… more
Abstract:In Phase I of this program, the research on a Low Cost Modular GPS/INS will be performed. This effort encompasses development of a general computer simulation that can be used for analyzing various GPS/INS mechanizations. A trade-off analysis of the GPS and INS modules will include different types… more
Abstract:The primary objective of this three phase (Definition; Detail Design & Development; Implementation) project is to create the generic core of a computer based Production Cost Model (PCM) to support Program Offices in their attainment of several Acquisition Reform Initiatives. The PCM supports the… 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.
