In an effort to improve and augment the navigation capabilities of autonomous underwater vehicles, researchers from Scientific Solutions, Inc. and the Massachusetts Institute of Technology propose to develop, design, and build a sonar system tailoredspecifically for concurrent mapping and localization (CML) technologies. A conceptual design stage will be undertaken to determine the optimal freque ...

We will optimize the design of a monolithic, highly-integrated, active/passive, two-color infrared detector capable of S/MWIR avalanche photodetection, (S)MWIR passive photodetection, or LWIR passive photodetection. The structure is constructed usingback-to-back photodiodes (one designed for unity gain or avalanche operation) manufactured with well-established, band-engineered HgCdTe heterostructu ...

An advanced fabrication technique is proposed to improve producibility, performance, and reliability of low vibration turbo-Brayton cryocoolers. The fabrication process will improve dimensional control in sub-miniature, high-speed precision rotors,allowing for further reductions in size without compromising the basic advantages of the turbo-Brayton cooler. During Phase I test rotors will be fabr ...

Advanced space-borne infrared sensor technology requires cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 to 1.0 W at 10 K, with additional loads at higher temperatures. A multistage cooler, capable of coolingmultiple loads, will offer large potential gains in system efficiency and weight. Turbomachine-based, Brayton cryocoolers are ideal candidates for ...

Composite Matrix Corporation proposes the development of a revolutionary new class of metal matrix composites (MMC) based on corrosion-resistant copper alloys and continuous fiber reinforcement producible at low cost using methods based on traditionalinvestment casting. The continuous-fiber structural preforms can be produced economically by a rapid laminating process. The calculated density, ba ...

Convective heat and steam pose serious threats to Navy personnel during fire fighting and damage control, but the only test environments available for testing of protective clothing for such conditions are large and very costly to use. The proposedconvective heat and steam test apparatus will enable rapid and low-cost evaluation of candidate fabric samples in the laboratory. During Phase I, a co ...

Solid State Scientific Corporation proposes to design and model a unique spectral imaging sensor that will be capable of simultaneously imaging four color bands at rates up to 200 Hz. The approach will use existing technology to improve multi-spectralimaging capabilities for missile threat warning by utilizing recent developments in micro-optics to create a four-channel spectral imager based on a ...

Solid State Scientific Corporation proposes to design and model a unique spectral imaging sensor that will be capable of simultaneously imaging nine color bands at video rates. The approach will use existing technology to improve multispectral imagingcapabilities for ballistic missile defense systems by utilizing recent developments in micro-optics to create a nine-channel spectral imager based o ...

The threat of terrorist or military attack using biological, chemical or radiological weapons is one of the largest concerns to U.S. military forces. Development of defense initiatives that can be implemented to neutralize agents and decontaminatepersonnel, equipment and buildings are required to counter the potentially catastrophic effects of such an attack. A family of biocides has been identifi ...
