DESCRIPTION (provided by applicant): The low frequency cardiac rhythm (LFCR) is a promising biological marker for psychological research. The primary goal of this project is to make the LFCR methodology more accessible to researchers by providing a both a product and extensive support services. In Phase I, a prototype system was built and used to collect simultaneous physiological and cognitive da ...

Current airborne sensors produce very large volumes of data, but the airborne battle managers aboard BMC2 platforms do not have the appropriate analytics to process this massive data. Lack of appropriate analytics represents a missed opportunity to extract additional and timely actionable intelligence, especially considering the fact that, in most cases, data bandwidth to the command center is lim ...

Cost-effective and minimally invasive monitoring of metastatic breast cancer (MBC) patients for disease progression or response to therapy is an unmet need in the clinical management of the disease. Imaging technologies are currently the gold standard of such monitoring. However, there is controversy regarding the type and frequency of imaging required. Imaging is expensive, time consuming, slow t ...

CRYOGENIC HELIUM REFRIGERATORS AND LIQUIFIERS CONVENTIONALLYEMPLOY OIL LUBRICATED POSITIVE DISPLACEMENT COMPRESSORS AT THE WARM END AND FREQUENTLY USE PISTON TYPE EXPANSION ENGINES AT THE COLD END. THESE SYSTEMS REQUIRE EXTENSIVE AND VIGILANT MAINTENANCE TO CONTROL CONTAMINATION FROM LUBRICATING OIL AND ITS VOLATILE COMPONENTS MIGRATING TO THE COLD END. HENCE THE NEED FOR LOW MAINTENANCE COMPRESSO ...

NASA seeks intelligent monitoring for hybrid and/or all electric propulsion systems, as well as methods to significantly extend the life of electric aircraft propulsion energy sources and their safety. The requirement to advance towards more fuel efficient and environmentally friendly aircrafts demands battery systems that can operate for longer periods of time in a safer and more reliable manner. ...

TECHNICAL ABSTRACT: Commercially available unmanned aircraft systems (UASs) are not well designed to meet requirements for many atmospheric measurement applications, including deployment from ships, long endurance, and low cost. Existing multi-rotor systems suffer from limited payload and endurance. Existing fixed wing systems offer improved endurance and payload, but require significant support h ...

Based on the success of developing high sensitivity laser vibrometers for landmine detections during the Phase I program, technologies are proposed for this Phase II research program to improve further the sensitivity and accuracy in locating buried landmines as well as increases in the efficiency and speed in scanning over the minefields of interest. Approaches to achieve these goals include the ...

Combustor Lean BlowOut (LBO) is a significant challenge in modern military gas turbine combustors. LBO can occur either during rapid engine deceleration or during operation at idle conditions with water/steam ingestion. Current practice is to design adequate safety margins to avoid the onset of blowout. However, significant engine performance improvements can be realized though the development o ...
