Abstract:Standard Digital CMOS silicon circuits will have high quality Thin Film emitters, and modulators integrated on to the silicon using epitaxial liftoff and results in low cost opto-electronics in the near future. ABJ Integration is a leader in the field and proposes to design an optimized FPA readout… more
Abstract:The U.S. micropropagation industry is a $24 million business supplying starter plant material to greenhouses around the world. However, in order to compete with the increasing numbr of offshore laboratories, U.S. micropropagators must produce higher quality plants more efficiently. The goal of… more
Abstract:INNOVATIVE TECHNIQUES ARE PROPOSED FOR INVESTIGATION IN A PHASE I EFFORT TO DETERMINE PASSIVE RF SURVEILLANCE AND TARGETING SENSORS AND ASSOCIATED METHODOLOGY FOR PERFORMING RAPID AND ACCURATE MEASUREMENTS OF RANGE/LOCATION OF OTH THREAT RF EMITTERS. THE ESSENTIAL PHYSICAL CONSTRAINTS TO BE OBSERVED… more
Abstract:Current designs for rural safety mailboxes combined with a lack of safety design regulations, produce a hazardous situation for errant rural motorists. When impacted, rural mailboxes have been shown to dislodge from their posts and penetrate automobile windshields. In addition, rural residents are… more
Abstract:An important aspect in the design of aircraft structure and aeropropulsion components made of high temperature composite materials is damage tolerance and life prediction. Many components contain joints between composites and metals. There is a need to develop methods for predicting life of such… more
Abstract:OHMIC CONTACTS ARE KEY TO THE IMPLEMENTATION OF SILICON CARBIDE (SIC) HIGH POWER, HIGH TEMPERATURE DEVICES. TO DATE, CONTACTS TO SiC MADE USING CONVENTIONAL TECHNIQUES HAVE DEMONSTRATED NEITHER LOW CONTACT RESISTANCES NOR LONG TERM STABILITY. IN PHASE I WE WILL DEVELOP LOW RESISTANCE SILICIDE BASED… more
Abstract:Infrared sensors and sensor arrays are widely used in military and commercial applications such as night vision, medical diagnosis and weather mapping. Expensive quantum effect sensors, such as HgCdTe systems, must be cooled to liquid nitrogen temperatures and are difficult to produce with uniform… more
Abstract:Structural composites have many applications to 2500 Degrees F and beyond, in oxidizing environments. Oxide fibers within intermetallic or oxide matrices are the top candidate systems for satisfying these conditions. Suitable fiber/matrix interface coatings are critical, but their development has… more
Abstract:The ability to control large amounts of power (1-150kW) is necessary in applications ranging from aerospace to consumer electronics to industrial power systems and transportation. In order for silicon and gallium arsenide devices to meet such high power densities, tens of devices must be combined to… more
Abstract:The superior optical properties of BBO and its applicability in frequency doublers and waveguides justifies development of thin film deposition processes which can be integrated with microelectronic processing. The high damage threshold of BBO, a necessary component for device integrity, is a major… more
Abstract:We propose to demonstrate the feasibility of solar-blind, multi-spectral III-V nitride UV detectors which can meet the requirements of applications in both the military and commercial sectors (missile threat warning, UV search and track, environmental monitoring in gas turbines, and general flame… more
Abstract:Spatial light modulators (SLM's) have been identified as critical elements in many optical computing and signal processing applications. Typically these devices use expensive bulk ceramics that result in high cost and difficult device integration. Ceramic materials in the PbLaZrTiO3 (PLZT) family… more
Abstract:Phase I will develop a gas-phase process for the deposition of low dielectric constant polymers for use in integrated circuits. This process will utilize the firm's liquid delivery technology to deliver the reactants and grow films at high deposition rates. Polymerization will be induced by thermal… more
Abstract:Radiation hardened ferroelectric random access memory (FRAM) devices have potential uses in numerous military applications. Until recently, FRAMs have relied on lead zirconate titanate (PZT) as the storage material. However, a new class of materials promises to offer higher device reliability and… more
Abstract:UV diode detector arrays have a wide range of both commercial and military applications. Examples include spectral measurement and calibration, pollution monitoring, environmental change monitoring, remote sensing of earth resources, solar UV monitoring, burner monitoring in gas turbines, flame… more
Abstract:Ultrasonic imaging is potentially one of the most versatile diagnostic tools in medicine, yet it istransducer designs. New applications of acoustical microscopy, performed at frequencies above 200 MHminiature transducer geometries to enable in vivo applications and to enhance present in vitro… 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.
