Abstract:Conventional electro-optic (EO) switches must have multiple electrode sections to ensure a producible polarization-insensitive device, which is impractical for high-speed operation and compact device integration. There have been great advances in achieving high-frequency operation using phase… more
Abstract:Conventional electrooptic materials failed to provide a polarization-insensitive switch unless an exotic electrode structure is employed. Such a drawback prohibits system insertion of electrooptic devices into an array of optical interconnection network. Radiant Research, Inc., proposes a novel… more
Abstract:To meet dependability requirements dictated by current trends in both defense and commercial technologies, massive modular redundancy and application specific designs will have to give way to more efficient, scalable and cost-effective approaches. This Phase I proposal introduces a method which… more
Abstract:The thrust of the proposed research is to develop a comprehensive and cost effective automated test insertion tool for boards and systems designed using Commercial Off-The Shelf (COTS) devices. The research will investigate promising test methodologies for testing non BIST devices in the… more
Abstract:The Critical-Time/Real-Time Database Management System is a Tandem Memory (Smart-Memory) which shares two memory functions. The memory functions are a Real-Time Data Memory (RDM) with separate I/O and a similar memory for storing of Distributed Data words (DDM) or parameters. Associated with each… more
Abstract:Systems & Processes Engineering Corp. (SPEC) proposed the development of a GaAs Field Programmable Gate Array (FPGA) for spaceborne applications. Digital Gate Array ICs combine functions of many logic gates into a single chip to improve speed, weight, and power dissipation. Field programmable gate… more
Abstract:Systems & Processes Engineering Corporation (SPEC) proposes to develop a Multi-Input Encoded/Decoder Application Specific Integrated Circuit (ASIC) chipset to be a programmable, universal interface between test equipment and digital recorders. The ASIC chepset will be fabricated using advanced GaAs… more
Abstract:Silicon and gallium arsenide cannot meet some of the power, frequency, temperature and speed requirements of the next generation of electronic devices. Therefore, alternative semiconductor materials for electronic devices must be developed. Silicon carbide has many required properties such as wide… more
Abstract:Systems & Processes Engineering Corp. (SPEC) proposes to apply a Taguchi Design of Experiments analysis to phased array antenna transmit/receive (T/R) modules. Large numbers of T/R modules are used in a phased array antenna and they have demanding specifications. By applying the appropriate… more
Abstract:SPEC proposes to develop a high throughput emulator chip which will provide direct execution of existing AN/AYK-14 and/or MIL-STD-1750 standard codes on commercially available 32-bit microprocessor workstations and PCs. The emulator chip will provide a low cost and time saving technology for … more
Abstract:The proliferation of laser applications in both the military and civilian sector is generating requirements for eye-safe laser systems. These requirements are becoming a major factor in operational decision making processes and are providing an impetus for researchers to find new ways to migrate… more
Abstract:Environmental monitoring is difficult because of the large number of potential pollutants and broad range of their chemical classes. A multi-analyte environmental screening and monitoring instrument which is fast, portable, species specific, fieldable, cost-effective and flexible is clearly… more
Abstract:The number of mines buried throughout the world and the cost to remove them demonstrate an urgent need for field-deployable detection technologies. Current technologies being developed are large and not man-portable. Biosensors and immunoassay techniques are excellent detectors for these low vapor… 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.
