Award Data

This proposal describes the development of an instrument based on laser-induced breakdown spectroscopy (LIBS) for the detection of lead in paint and soil that will have both military and commercial applications. The Phase I instrument will be similar to multi-species, portable LIBS instruments built by Dr. David Cremers at Los Alamos National Laboratory that utilize a spectrograph/charge coupled ...

Previous measurements using two micron solid-state lidar systems and computer simulation of lidar performance demonstrate that an eyesafe, low-pulse-energy (1 - 10 mJ/pulse), small aperture (~10cm) lidar will be capable of highly accurate high spatial resolution wind velocity measurements to ranges of 2-10 km in the atmospheric boundary layer. High-spatial resolution 3-D coverage for several km a ...

The OpTest system has been conceived of and demonstrated in response to pressing diagnostic needs. It is an immunosensor device to enable detection of BW agent specific antigens or extracellular products and toxins, using "capture" and "detection" antibodies, at picogram or sub-picogram levels, from biological fluids. OpTest also is capable of detecting BW agent specific nucleic acids which are ...

40765 November 13, 1996 Detection Limit, Inc. Cone Penetrometry, when coupled with a chemical analysis capability, is a powerful method for subsurface mapping of contaminants. However, the fluorescence techniques used to get the qualitative and quantitative chemical information do not have the ability to detect such nonfluorescent materials as chlorinate ...

Digital Wave Corporation proposed to develop a novel nondestructive testing (NDT) system for high speed acquisition and analysis of wide band acoustic emission (AE) waveforms. The system will provide the capability to detect, identify and locate crack growth in loaded steel structures. This system will incorporate the new high fidelity sensor developed by the Federal Highway Administration and a ...

Untethered head mounted displays must be battery operated to achieve the benefits of mobility expected for them. Thus, the display element inside should operate at low voltage and consume small amounts of power to provide maximum battery life. Battery operation also demands that the display element make the most efficient possible use of electrically produced light which illuminates the display. ...

40501 Eltron Research, Inc. This project will develop and implement a small, portable monitor for flow injection analysis of uranium in liquid sample streams, (e.g., nuclear plant effluent). The device will be capable of remote, unattended sampling and detection of analyte without intervention by an operator. The detector will be able to monitor uranium concentrations from the sub-nanomolar ran ...
