In the high noise environment of fixed and rotary wing aircraft used for casualty evacuation, a critical need exists to detect normal vs. pathologic heart and breath sounds and discriminate among their components. Evaluations by the Army staff at theU.S. Army Aeromedical Research Laboratory has demonstrated that no such capability exists whether in standard acoustic stethoscopes or electronic no ...

Active Signal Technologies proposes a thoroughly planned systematic development effort to produce a system that will meet the requirements of rugged operational monitoring to provide continuous electrocardiogram (ECG) and ventilation data on activelydeployed personnel. The program starts with a comprehensive literature survey across a broad range of life sciences, technology and government resear ...

The objectives of this research are to fully design and develop a prototype of an environmental impact assessment and mitigation software suite, focusing on the impact of active acoustic emissions on marine mammals. This software will be: web-enabled,cross-platform capable, and be applicable throughout the life cycle of active source programs. Databases of biological data, environmental regulat ...

Even when built to exacting standards, towed arrays invariably suffer acoustic sensor failures. A relatively small number of sensors can have large negative impact on beamformer side-lobe levels. This SBIR program will develop, implement, and integrate atowed array beamformer shading algorithm that provides robust performance as hydrophones fail. The selected algorithm must provide better acoust ...

Traditional CBM Predictive Maintenance systems, in which the sensors are either hardwired or else read by periodic

The research proposed here is built on the recent successful fabrication of metal oxide semiconductor heterjunction field effect transistors (MOS-HFETs) based on AlGaN/GaN heterostructures with very high drain-current-driving and gate-control capabilitiesas well as unprecedented high breakdown voltages by the P.I.s research group at Kansas State University. III-nitride HFETs have great promises i ...

The attack against the USS Cole clearly showed the vulnerability of surface ships to close-in attack from an explosive charge. The objective of this proposal is to examine technologies that offer enhanced protection of ships against asymmetric attackusing high explosives. The concepts to be investigated include the use of energy absorption sandwich panels using various core designs such as corru ...

ATEC, in collaboration with an OEM partner and University of Maryland's Center for Environmental Energy Engineering, propose to develop an innovative oil separator and a heat exchanger with a novel manifolding system for CO2 heat pumps. These twocomponents will eliminate some of the shortcomings of CO2 heat pump systems.Traditional oil separators cannot effectively remove oil from supercritical C ...

We propose to develop a superior thermal management system for high-power radar T/R modules at the Lower Replaceable Unit or LRU board level. We will incorporate evaporators into a new LRU board such that an evaporator is adjacent to each T/R module. Ourunique and proprietary thin-film evaporators remove large amounts of heat via ultra thin-film evaporation of a working fluid. After evaporation ...

We propose to develop a T/R module housing that incorporates two-phase thin-film evaporators adjacent to each T/R module in order to increase greatly the lateral spreading within the housing. Our unique thin-film evaporators remove large amounts of heatvia ultra thin-film evaporation of a working fluid. After evaporation, the fluid's vapors pass through a semi-permeable membrane and condense on ...
