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- ...

The goal for our research is to devise effective haptic information delivery with minimal training. To do this requires engaging pre-existing haptic perceptual capabilities. It is unrealistic to expect that large numbers of Soldiers will train for hundreds of hours to master a complex haptic information display, particularly, if its use would capture most of their attention in battlefield situati ...

Ozone treatment of wastewater to destroy organic contaminants prior to discharge into the environment is an extremely effective advanced oxidation technology. To date the use of this powerful technology has been limited in part by the relatively high capital costs of an efficient ozone to water, gas-liquid, mass transfer system. Existing ozone injection devices must overcome the inherently low m ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

Low cost compact diffusers are needed for small gas turbine compressor stages to economically minimize centrifugal compressor overall diameter yet permit high efficiency and wide operating range. The proposer has performed over 130 different detailed tests (on more than 40 different stage configurations) with various conventional and novel diffusers (vaneless, low solidity airfoil, channel, tande ...

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 ...

Tunable HF/VHF filters capable of operating at high power levels are needed for preventing a jammer from interfering with nearby friendly communications, high-speed antenna tuners, and output filters for high-efficiency power amplifiers (PAS). Filter systems presently employ either relays or pin-diode switches to select one filter from a bank of filters that spans the operating frequency range. ...
