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 ...

Fiber & Sensor Technologies (F&S), teaming with Virginia Tech, proposes to develop an adaptive control system for cure of thermoset resins during manufacture and repair of polymer matrix composites. Leveraging DOD-sponsored development of fiber optic cure monitor sensors, F&S will develop an embeddable "sensor string" by multi-plexing pressure, temperature, and viscosity sensors on a single optic ...

DIAGNOSTx Technologies proposes to develop a PC-based instrument for the clinical evaluation of peripheral and central hearing deficits, which will allow audiometric, otoacoustic emissions, evoked-potentials and immittance testing. The integrated system will be capable of assessing hearing sensitivity for speech and pure tones, of evaluating the integrity outer hair cells and auditory central ner ...

This Phase I SBIR will develop a general purpose probabilistic finite element analysis system, ProFEA, that allows designers to perform probabilistic finite element analysis in a graphical environment that is completely familiar and similar to modern deterministic FEA. We have developed an innovative architecture that takes advantage of emerging file exchange and database standards (I ...

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 ...

The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper wear patterns and gouging phenomena throughout the sled velocity regime to Mach 10. This will inclu ...
