Wind noise in outdoor measuemetn micropnones can mask an acoustic signal. Windscreens provide some wind noise reduction; however, those typically used for outdoor applications provide noise reductions of approximately 10-15 dB. Planning Systems Incorporated (PSI) proposes to design and test a Multiple Aperture Sensor System (MASS) consisting of a microphone, a processor, and data acquisitio and ...

The production of semi-conductor wafers is a multibillion dollar industry. The 1996 worldwide semiconductor market is estimated at $162 billion with a growth potential to $309 billion by the year 2000. Thus, even a small improvement in control during the manufacturing process could have a large impact on the economic viability of many companies and products. A critical factor in all semiconduct ...

Bends in waveguides are a problem for high-voltage Ultra-Wideband (UWB) systems. The difficulty arises because only a straight section of standard transmission line can support a pure TEM mode. And a pure TEM mode is necessary to preserve the risetime of the transmitted impulse. When there is a bend in the waveguide, the transmitted signal is a broader impulse than the incident signal. This ca ...

Presently there are no broadly tenable, narrow linewidth souces that operate throughout the mid-infrared (mid-IR) region of the spectrum, from 1 to 5 microns. Traditional sources have very low spectral brightness (low power per unit spectral bandwidth). This proposal describes a novel approach to produce a source with very high spectral brightness, tunable over the range of 1.1 to 4.3 microns. ...

The proposed product, called Pro-Tech-Tube Infectious Shipper (PTTIF), will enable health care workers in military or commercial laboratories to ship diagnostic substances that may contain infectious microorganisms (including Level 1, 2, and 3 in the DoD Biological Defense Safety Program, Technical Safety Requirements) as FDA regulated biological products. Such products are not subject to current ...

With the development of compact, rugged laser diodes that can be powered with bateries, it appears that medical procedures that utilize lasers can now be brought into the field environment. The goal of this effort is to develop a fieldable laser diode tissue soldering system for wound stabilization. In this technique, a laser is used to thermally cure a protein solution placed onto a wound. Thi ...

The Cesium vapor magnotometer and ground-penetrating radar senors currently used to identify subsurface Unexploded Ordnance locations also respond to underground clutter and anomalies. The ultimate objective of this project is to develop a classifier or discriminator that has the potential of providing significantly improved performance on target discrimination for subsurface ordnance ...
