As an alternative to double-base propellants we propose electric solid propellants (ESP) as a safe, green, higher performance alternative to double-base propellants for high velocity electro thermal chemical (ETC) canons. These new energetic materials are inherently safe, with ignition only possible via the sustained supply of electrical power and not by spark, flame or even bullet impact. A maj ...

The objective of this research is to enable pre-process milling parameter selection for"first part correct"production. In the proposed solution the Receptance Coupling Substructure Analysis (RCSA) approach will be used to couple the measured spindle-machine dynamics to models of the tool and holder and predict the assembly"s dynamic response. Given this information, frequency/time-domain algorithm ...

In the current SBIR program, AlphaSense aimed at developing a novel, handheld, non-destructive sensor to evaluate the integrity of Naval Advanced Amorphous Coatings (NAAC) in real time. In phase I, we have proven the feasibility of using the cavity perturbation technique to detect different types of defects present in thermal-sprayed testing coupons. Specifically, we optimized the sensor probe des ...

Commodity graphics processing units (GPUs) offer tremendous computational throughput for relatively little cost. They have been shown to outperform microprocessors in the important metrics of FLOPS/dollar, FLOPS/Watt, and FLOPS/unit space and have already been applied to a wide range of numerically intense problems. In Phase I of this project, we demonstrated their potential to enhance complex C ...

This Phase II proposal intends to design and develop a robust wireless video image sensor system capable of long term reconnaissance and surveillance deployment. Video images of targeted object would be captured via an all-weather, low-light, high resolution camera and broadcast to locations world-wide through satellite communication transceivers. Command centers as well as tactical patrols near t ...

MOUTHSTICKS OR ORTHODONTIC ORTHOSES ARE WIDELY USED BY PEOPLE WITH SPINAL CHORD INJURIES OR SIMILAR DISABILITIES TO INCREASE CONTROL OVER THEIR ENVIRONMENT. PEOPLE WITH THE ADDITIONAL LIMITATION OF LITTLE OR NO ANTERIOR/POSTERIOR HEAD MOTION MAY BENEFIT FROM AN EXTENDIBLE MOUTHSTICK. HOWEVER, COMMERCIAL EXTENDIBLE MOUTHSTICKS SUFFER IN THAT THEIR ACTION IS OFTEN SLOW, EXTENDIBILITY IS LIMITED, OR ...

Pressure ulcers are a serious medical problem with annual treatment costs over $1 billion dollars. While the exact etiology involves a complex combination of factors, it is generally accepted that prolonged pressure to soft tissues results in discrete areas of acute ischemia. If the pressure is not relieved and the blood supply restored in a critical length of time, endothelial cell damage will re ...
