A CONTROLLED RELEASE ANTIBIOTIC WOUND DRESSING IS TO BE DEVELOPED FOR ADMINISTRATION OF BACITRACIN AND POLYMIX B. THE DRESSING IS TO BE EASILY APPLIED AND CONFORMABLE TO WOUND SURFACES. BOTH ANTIBIOTICS ARE TO BE MAINTAINED AT EFFECTIVE LEVELS WITHIN WOULDS FOR THREE DAYS, PREVENTING INFECTION FOR THIS PERIOD OF TIME. THE DRESSING IS TO BE INCORPORATED INTO POROPLASTIC CELLULOSE TRIACETATE MEMBRAN ...

SIMOX (Separation by IMplanted OXygen) technology achieves total dielectric isolation of active device regions from the substrate and reduces the collection path for ionized charges via the built-in buried oxide which restricts charge movement. Advances in SIMOX technology include radiation hardened memories and gate arrays for space applications, ULSI DRAMs for low voltage operation, thin film l ...

New power semiconductor device performance is limited by cooling because high heat-flux cooling systems have not matched their increased power density. Therefore, real designs rarely achieve device ratings. American Superconductor (ASC) demonstrated CryoPower+, which cools a variety of power MOSFET topologies by direct immersion in coolants from 77-300K, with boiling where appropriate. CryoPower ( ...

High pixel count display operation at high frame rates requires high frequency display circuits and a fast light modulation media. Kopin's AMLCD display technology utilizes fast CMOS circuits fabricated in single crystal silicon, which are superior to circuits fabricated in poly-crystaline silicon and amorphous silicon. Display circuits are fabricated on SOI wafers in conventional CMO ...

AL/AOCF noted that the accurate evaluation of hearing acuity depends on the ability to attenuate background noise during audiometric testing. Audiometric testing efficiency can be improved and cost significantly reduced if headphones with the capability to attenuate noise can be utilized to accurately transmit test signals precluding the need for a traditional sound room. USAF described the prob ...

Physical Sciences Inc. (PSI) proposes to show the feasibility of using a novel, spectrally-selective IR imager for the passive standoff detection of chemical agents and hazardous chemicals. The concept is based on the insertion of a tunable etalon into the field-of-view of an IR imaging system. The approach takes advantage of recent advances in the development of staring IR focal plane arrays, w ...
