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 ...

The development of an immersive environment to visually simplify complex situations, by minimizing distractions and maximizing information presented to the user, promises to re-define the current man-machine computer interface. This proposal will define a prototype for a seated immersive interface to transport the user around in an artificial/virtual environment. The environment will surround th ...

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 ...

Turboshaft engines are subject to various transient modes, necessitating a compressor with very high surge margin. Therefore, many devices were proposed in the past, and some of them including a recent one with a vaneless cavity by Allied Signal Engines, demonstrated impressive surge margin enhancement. However, there ahs been no detailed investigations on understanding the flow mechanism leading ...

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 ...

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. ...

An inorganic photoresist system involving only dry processing has many potential uses in microelectronic fabrication. Reduced wafer contamination and simpler waste disposal requirements will provide a strong driving force for replacing existing wet photolithographic processes with the new system. At the completion of this project, a new inorganic resist system utilizing hydrogenated amorphous si ...

Radiometric Corporation proposes to apply a new microwave technology to profiling of atmospheric water vapor. Water vapor is the most significant and most highly variable of greenhouse gases. It is also the most significant and highly variable atmospheric constituent in the formation of weather and in the transfer of atmospheric heat. Yet it remains one of the most poorly characterized of meteo ...
