DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

Various technologies available to space system designers that operate at different voltage levels. It is, however, important to interface, maintain, and update these systems. For example, the Sun Earth Connection (SEC) missions are likely to have a variety of experiments needing to be accomplished with a single nanosatellite. A rad-hard reconfigurable bi-directional level shifters would allow th ...

The pressing need exists within industry to accurately measure high aspect ratio microscale structures. For example, diesel injector nozzles are manufactured with microscale holes ranging from 50-200 micrometers in diameter and 3-5 mm depths. One fundamental challenge is to nondestrucvely measure these features in order to validate models, enhance manufacturing processes, and reduce fuel emissions ...

Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The instrument is modular, rugged, compact and highly sensitive. Volume pricing will be less than $1000 each. ...

Computational fluid dynamics (CFD) is used as an analysis tool to help the designer gain greater understanding of the fluid flow phenomena involved in the components being designed. The next step in the design process is to modify the design to improve the components performance, typically performed manually by the designer in a trial and error fashion. The innovations proposed herein will provide ...

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...

Field emission electric propulsion (FEEP) thrusters have gained considerable attention for spacecrafts disturbance compensation because of excellent characteristics. The application of current FEEP has been slow in developing mainly caused by high specific power, which limit the milli-Newton thruster development due to insufficient onboard power. Dramatic field improvement from nanometer carbon ...

"The DNA microarray is a powerful new technology that can be applied to the detection of biological warfare agents. For the detection of multiple agents, tremendous challenges lie ahead for the DNA microarray technology regarding on sensitivity,selectivity, reliability and consistence. The central theme of this proposal is to apply and optimize a newly developed DNA probe: Molecular beacons (MB) ...

We propose a new broadband electromagnetic (EM) sensor, called GEM-5 (Figure 1), to measure the electrical conductivity of the first 5-10 m of Martian in-situ geology. The depth of exploration may increase with a higher transmitter power. While the sensor can be used for exploring other planets and moons, this proposal is directed specifically to a small rover such as the 1997 Sojourner to Mars. T ...
