We propose the continued design, development and testing of spherical piezocrystal transducers and supporting technology including our gyroid transducer. The Phase II effort covers the modeling and demonstration of the gyroid transducer and comparison of performance with several piezocrystal and piezoceramic materials and testing in realistic environment. The electroacoustic performance will be es ...

Key obstacles to extending OFDM to wireless links and networks at high frequencies with dynamic channels are inherent low performance to Doppler and power amplifier operation with high backoff. Other significant obstacles are multipath and impulsive noise. PEARL provides a solid communications infrastructure with support for incremental relevant capabilities including TRANSEC and LPD/LPI. For this ...

A yb laser at 976 nm is a three level system. By placing Sm in the core (to reduce stimulated emission above 1,000 nm) and Yb in a surrounding ring, a more efficient laser at 976 nm can be obtained. This will be Q-switched to serve as the first stage of a pulse source in a MOPA configuration. The second stage will be a HOM fiber designed to amplify the pulses from the first stage. With a HOM fiber ...

The ultimate objective of this SBIR project is the development of a software-based tool that provides environmental planners, synthetic trainers, and scientific researchers with access to scientific data on marine species. Ready access to pertinent information about a marine species, such as distribution, density, and behavior, is vital for making informed science-based decisions concerning the ma ...

"Ocean Energy Extraction for Sensor Applications" has applications on buoy systems to be used by the United States Navy to increase situational awareness and battle-group integration by enabling power independent data acquisition and distributed sensor networks. Electro Standards Laboratories proposes to meet the requirements with mechanical wave energy extraction accomplished using integrated ele ...

The overload of electronic equipment presents a liability for warfighters, with batteries greatly adding to equipment weight and cost. The objective of this research project is to continue development of autonomous power management circuits that will lighten the load for warfighters by extending battery life in military notebooks and radios. In Phase I, Packet Digital demonstrated a 28% reduction ...
