"Active Signal Technologies proposes to develop an active noise reduction (ANR) stethoscope that will enable detection and discrimination of heart and breathing sounds in the high noise environment of a UH-60 BlackHawk helicopter. We will enhance ourdirect contact sensor technology, which already provides state-of-the-art physiological signal detection and passive noise rejection, to better match ...

"The next generation USW combat system will implement improvedactive/passive sonar processing in a COTS architecture. Shipboardsensors include radar, hull array, towed array, and sonobuoys.The sonar analyst must efficiently manage a huge increase ininformation to realize the full potential of future underseawarfare sensors. Since operator workstations and sonar watch teamsize is limited, reliable ...

"The objective of this proposed research is to define a USW tactical data fusion architecture and develop a fusion algorithm baseline that can continue to mature through an incremental technology and software build process. Phase 1 program emphasis will beplaced on data fusion algorithm assessments and architecture definition for the USW combat system application. AHA will develop an overall data ...

"The objective of this research is to research alternatives of a total planning system solution for use of environmental sensor data for the tactical ASW warfighter. The software will plan an integrated deployment strategy for both environmental andtactical sensors prior to takeoff. It will run rapidly and take into account trade-offs of using environmental sensors. During the flight the softwa ...

"The objective of this research is to produce an environmental sensor simulation system (ESSS) that will support advanced research and development for ASW. Efforts are underway to design new environmental sensors that will enable accurate, timelymeasurement of the ocean environment, especially for the shallow littoral regions where the environment is highly variable in time and space. One such s ...

"In future advanced military diesel engine propulsion systems, the engine's tribological considerations have been limited by the temperature capability of the lubricating fluid. Thermal oxidation resulting in lubricant breakdown and formation of films anddeposits are typical causes of engine failure in the high operating conditions projected for Low Heat Rejection (LHR) type diesel engines. Work ...

"A small engine concept is being proposed for a 0.25 cid two-stroke commercially available engine that will allow the elimination of volatile fuel additives and lubricating oil. The concept will lead to fuel consumption improvements and increases in powerdensity in heavy-fueled small bore homogeneous compression ignited engines. The concept includes the use of solid lubrication coatings and therma ...

"This proposal comprises research efforts to study a dynamic non-stationary friction regime with a variable range of external factors or parameters. This research method considers the development of special non-linear mathematical models for enginetribology including the lubricating oil film thickness as a function of a series of independent parameters in extreme working conditons. These models ...

"This Phase II Proposal outlines a development plan for a low-cost Wireless PLC unit to address the need for reduced cost of wiring, installation, and maintenance for shipboard control systems and commercial manufacturing plants. The challenge of thesesystems is the thousands of feet of hardwiring to sensor and control inputs. The Phase I effort resulted in a working, wireless software demonstra ...
