Advancements in subminiature earphone drivers are sought to provide desired improvements in active noise reduction (ANR) earplug attenuation magnitudes and bandwidth. Prior investigations have illustrated a need for improvements in frequency response, sound power output, geometrical configurations, and ease of manufacturing for drivers that are optimized for military ANR earplug applications. Th ...

Recent spectrum study shows that while the available spectrum becomes increasing scarce, the assigned spectrum is significantly underutilized. In this project, we propose an integrated effort to develop a new radio technology capable of dynamically sensing and locating the unused spectrum and communicating using the unused spectrum in a way that causes no harmful interference to the designated us ...

In many cases the analyst's problem is one of finding a needle in a haystack. The ever increasing flood of communication technology and traffic has resulted in a large and growing haystack and presents a daunting problem. The key to maximizing analyst productivity is the development of intelligent tools which automatically and accurately extract potential activity of interest while only rejectin ...

The proposed research will demonstrate the technical feasibility of fabricating an effective screening system that will detect explosive materials. The system will be single-sided exposure and detection scheme permitting standoff distances of 1 meter or more. The system will consist of a new, high-intensity, portable neutron source that exposes the subject article and a detector that analyzes th ...

Manufacture of polymer matrix composite (PMC) jet engine parts is expensive due to the high cost of needed high temperature materials and fabrication processes currently in use. To reduce costs and improve quality, automated composite fabrication methods such as filament winding, automated tape placement, and fiber or tow placement coupled with non-autoclave processing offer great promise for use ...

The future generation of both military and commercial diesel engines will operate at significantly higher temperatures and pressures than today's engines. The future combat system diesel engine operating parameters demand significant design improvement of in cylinder insulation. Increased cylinder pressure and reduced cooling requirements, heat energy recovery in the exhaust gas by turbo chargin ...

A high-power density, low specific heat rejection diesel engine design for traditional and hybrid future combat system (FCS) vehicle configurations is being proposed. The total propulsion system of the vehicle hybrid configuration will fit the future vehicle assigned space/volume by TACOM's vehicle concept laboratory. The proposed engine will have a high-pressure common rail fuel injection syste ...

Blood loss due to uncontrolled hemorrhage is a major contribution to at least 90% of the combat death before reaching the field hospital. The ability to control heavy bleeding in the injured soldier is critical and will vastly improve the survival outcome in the theater. Furthermore, complications from uncontrolled bleeding in the microvasculature contribute significantly to increased morbidity. ...

Adlyfe Inc. has developed a highly sensitive fluorescence based test, called the Misfolded Protein Diagnostic (MPD) Assay, for the misfolded prion protein associated with infectivity. The femtomolar sensitivity of the test enables the presymptomatic detection in blood, which can be performed ante mortem in routine surveillance of live animals and in blood screening of the human blood supply. The ...
