The military needs better methods of monitoring remote facilities to protect them against burglary and vandalism. Many of these facilities cover large areas, contain numerous buildings and other valuable assets, and are at high risk for theft. New acoustic monitoring technologies are needed that will allow deployment of large numbers of low-cost, autonomous sensors. Each sensor must provide rel ...

Traumatic Brain Injury (TBI) has been called the signature wound of Operation Iraqi Freedom. The rise in overall survival rates and increase in brain injuries can be attributed to advances in medical technology and Kevlar body armor, which effectively protects soldiers from otherwise fatal blows, but leaves the head and neck area unprotected. The most frequent cause of injuries among more than 2 ...

THE GENERAL PURPOSE ICE DETECTOR/ACCUMULATOR PROPOSED IN THIS DOCUMENT EMPLOYS TWO ULTRASONIC SENSING MODES. RAYLEIGH WAVES (SURFACE WAVES) ARE USED TO DETECT THE ONSET OF ICING, AND TIME-OFFLIGHT MEASUREMENTS IN A NORMAL INCIDENT REFLECTION OF ULTRASONIC PULSES FROM THE ICE LAYERS ARE USED FOR MEASURING APPRECIALBE BUILDUP THICKNESS OF THE ICE (>0.5MM). THE BASIC PRINCIPLES UNDERLYING A TIME-OF-F ...

Aspen Systems Inc. proposes to develop a proprietary antenna cooling system for Satellite Communications on-the-move (SATCOM OTM) applications. This system will replace an existing thermal control unit with a lighter and higher performance system designed to keep the antenna electronics cooler than existing systems and cooler than ambient. The system will consist of a series of heat exchangers i ...

Increased demands for electric vehicle performance have resulted in large power requirements and the potential for extremely large fault currents. This is true not only for over-the-road electric and hybrid vehicles, but also for ships and aircraft, which are increasingly moving toward all-electric propulsion. Without fast and reliable means to limit fault currents and isolate faulted sections, ...

The Army seeks to standardize all equipment on its battlefield logistics fuel, JP-8. JP-8 is difficult to use for small-scale, low-power applications, however, since its low vapor pressure and complex composition inhibit complete vaporization. Existing methods for vaporizing logistics fuels are not sufficiently controllable to support highly efficient catalytic combustion processes, or impose un ...

During Phase II period, Hstar plan to prototype an advanced mobile robotic nurse assistant (RoNA) system for augmenting nurses’ health care capabilities in a hospital environment with physical assistance. This RoNA system will: a) navigate intelligently in hospital environments with a mobile holonomic drive, b) support an intuitive interface guided by human-robot interaction and work safely and ...
