This proposal describes a new approach to laser diode drivers which combines the unique advantages of three key technologies. The innovative approach will extend the performance capabilities of laser diode systems to greater than 200 A peak pulse current, less than one nanosecond rise time, at greater than 10 KHz repetition rates. Not customarily used in laser diode drivers, the unique combinati ...

THERE IS A CRITICAL NEED FOR A FAST, SIMPLE SENSOR FOR AQUEOUS MERCURY IN WASTE, SURFACE, AND GROUND WATER. THIS SENSOR IS REQUIRED FOR THE DOE REMEDIATION EFFORTS AS WELL AS THE MORE WIDESPREAD EFFORTS IN ENVIRONMENTAL PROTECTION. SUCH A SENSOR SHOULD BE ABLE TO REACT TO NANOGRAM PER MILLILITER LEVELS OF MERCURY. THE SENSOR IS CAPABLE OF DIRECT IMMERSION IN SOLUTION AND SHOULD PROVIDE CONTINOU ...

Immunization has proven to be an effective method of protecting both military and cibilian populations from disease caused by bacterial, viral, or toxic agents. The U.S. military faces the problem of protecting its personnel from incapacitation caused by exposure to agents of both natural and man-made orgin. In developing countries, immunization is the most cost-effective weapon for disease prev ...

This project seeks to demonstrate the derivation of 60 Hz AC power direct from the output of high frequency alternators through a novel use of solid state controls. The independence of output frequency engine/driver speed will be demonstrated. The ability of these alternators to handle reactive power loads at 60 Hz will be investigated. The potential for producing useful levels of MIL-STD (60 H ...

The objective of this proposal is to determine the chemical operating parameters and control parameters required to design a Neutral Precipitation/Cross Flow MicroFiltration wastewater treatment unit for removal of heavy metals from wastewater generated in the metal finishing operations generated at Department of Defense arsenals and depots. The proposed wastewater treatment process would permit t ...

Event Tracking Service (ETS) proposes to study the feasibility of developing a low cost ($50), self-contained, dual use, miniature, credit card size Environmental Measurement Device (EMD) to sense and log shock, vibration, temperature, and humidity. The device would be readily expandable to monitor other parameters. Our low power architecture includes 3V off-the-shelf CMOS electronics, a low power ...

This program will demonstrate the fabrication of ultra lightweight/high performance composite annular electrodes incorporating the reliability, via strength and toughness, necessary to facilitate efficient, simple assembly of low cost PEM fuel cells for lightweight extended duty cycle portable power sources. New and innovative composite manufacturing techniques will be employed which offer a low ...
