Current gearbox life estimation techniques commonly underplay the significance of gear tooth surface fatigue due to the complexity of the phenomenon involved. The Phase I program successfully demonstrated the feasibility of utilizing advanced modeling techniques to predict the onset and propagation of surface and bending fatigue in spiral bevel gears, including an analysis of mixed-elastohydrodyna ...

In this proposal, AlphaSense, Inc. proposes to develop an innovative real time probe for online monitoring of plastic bonded explosive manufacturing process. Key innovations of the proposed sensor probe include: a) the use of a white light interferometer (WLI) to form real time images of the particles for accurate particle size measurements, and b) the use of quartz crystal microbalance (QCM) base ...

Mid-infrared (MWIR, wavelength ~10 micron) imaging has significant importance in military surveillance and target recognition, since human body radiation peaks in MWIR. The GaSb/InAs type-II Strained Layer Superlattice (SLS) MWIR detector has been under intensive investigation recently. While much progress has been made to enhance wavelength coverage, one of the few remaining issues has been its r ...

Low light level infrared imaging has significant importance in military surveillance and target recognition. The proposed broadband low-light-level nano-BiCMOS camera covers visible and near infrared bands from 400 nm to 1,550 nm wavelengths. With a proven nano-technology, the proposed nano-BiCMOS photo-detector solves this long-standing tradeoff between quantum efficiency and dark current by in- ...

Recent advances in computing have produced special-purpose hardware comprised of vector processors streamlined for high-performance computations. Development of these devices, such as graphics processing units (GPUs) and the Cell Broadband Engine (Cell Processor), has been advanced by the videogame industry. In an effort to increase flexibility and enter new markets, vendors have increased platf ...

Aging and newer composite aircraft fleets have led to the need for advanced damage detection systems. Inspections for damage in the field are limited due to equipment capability, size/weight, automation challenges, human error and disassembly issues. A portable, lightweight, robust inspection system powered by an user-friendly, automated software system, with remote scanning capability, could imp ...

The feasibility of ANP's proposed seld-calibrated rapid test forf AChE inhibitors has been clearly shown in Phase I. Its compatability with ANP's handheld reader for immuno-assay based threat agent rapid testing has been confirmed. Phase II will finalize the design for robustness, full integration with the ANP handheld reader, manufacturing and affordability. Expansion of testing to include a w ...

Imaging sensors are a crucial component of modern defense. The ideal sensor has acute visual sensing capabilities and communicates instantly when threats are identified. It should also have night vision capabilities and cover a broadband spectral range including near ultraviolet and infrared. A robotic broadband night vision camera is highly desirable. Such a robotic broadband low-light-level came ...

This proposal addresses development of highly oxygen permeable perfluoromembranes for Lithium-Air organic electrolyte batteries. These batteries have demonstrated very high specific capacity (greater than 500 Wh/kg) at low rates in pure oxygen. Oxygen from the air can be utilized if a membrane is developed that allows for oxygen transport but prevents solvents in the organic electrolyte from diffu ...

Compact Membrane Systems, Inc. (CMS) has been a pioneer in modifying the air charge to diesel engines with air separation membranes. Nitrogen-enriched air (NEA) supplied from polymeric membranes mounted on highway truck diesel engines have been shown to substantially reduce the NOx formation and emissions from the engine. The NEA membrane’s co-product, Oxygen-enriched air (OEA), when supplied ...
