We propose to further develop a new technique for imaging underground facilities based on the passive monitoring of acoustic emissions from both stationary and moving equipment within such facilities. It is well known that all mechanical devices, such asmotors, gears, etc, emit acoustic signals. It is possible to identify an acoustic source based on its noise spectrum. During Phase I, we have demo ...

The basic objective of this Phase II Small Business Innovation Research (SBIR) is to build on the results of the Phase I feasibility study and to further research on the underlying technologies by developing and demonstrating a prototype Tactical UserAntenna (TUA) subsystem. The Phase I effort established the feasibility of investigating user requirements, investigating and assessing the availabi ...

The goal of this project is to characterize changes in human voice characteristics as the speaker becomes fatigued and to use this information to design an effective, remotely monitored, fatigue assessment system. The need for remote, near-real-timeassessment of personnel during ongoing operation is critical, given the long and irregular duty hours required of military personnel combined with the ...

Corvid Technologies approach for improving munition technologies is to design an asymmetric shock propagation barrier (ASPB) with reactive composite materials (RCM) to enhance functional and lethality characteristics over traditional shock attenuation barriers. In Phase I, we teamed with Shock Transients Inc. (STI) to develop, evaluate, and fabricate a two-layer ASPB concept using MPXITM, an RCM d ...

The proposed semiconductor-insulator-semiconductor (SIS) is herein defined as a structure consisting of two semiconductor layers separated by an insulator. PTS proposes such a SIS structure as a latching on/off switch consisting of widebandgap (WBG)semiconductors as cathodes and anodes. The cathode will be designed as an efficient electron gun or cathode. The anode will be designed as both an effi ...

The Bennett Advanced Research Team proposes to create spacecraft structures embedded with wires and other sensors creating a multifunctional structure.

The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...

THE OBJECTIVE OF THIS PROPOSAL IS TO CONDUCT PRELIMINARY TESTS ON A NOVEL CHEMISTRY WHICH COULD RESULT IN THE PRODUCTION OF A LOW COST WAFER WHICH CHANGES COLOR UPON EXPOSURE TO WARFARE GASES (WG). SIMILAR WAFERS WHICH WE DEVELOPED FOR OTHER GASES ARE ABOUT 2" X 1" X 1/16" AND WEIGH ABOUT 2.3 GM. THESE CHROMOSENSE (TM) WAFERS CAN DETECT HYDROGEN SULFIDE, ETC. IN 10-30 SEC. AT CONCENTRATIONS OF THE ...

Kyma Technologies, the leading domestic supplier of crystalline III-N substrate materials, is teamed with leading AlGaN materials & device experts at Sandia National Laboratories (SNL) to develop high-quality n-type conductive 2-inch diameter epi-ready free-standing AlGaN substrates in support of next generation AlGaN devices with applications in ultraviolet optoelectronics, power electronics, and ...

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 ...
