Body armor used today is an achievement of modern science, constructed of high tensile strength, manmade fibers and ultra hard, impervious ceramics. As impressive as this armor is, however, one of the most critical areas of armor testing methodology has remained largely unchanged from its National Institute of Justice (NIJ) 0101.00 roots: back face signature (BFS). The somewhat arbitrary value ...

Fire Solutions LLC will demonstrate a vehicle crew fire protection system that utilizes both water mist and aqueous foam subsystems in a Phase I effort utilizing a steel simulated"Humvee"built by Naval Air Warfare Center, China Lake. The proposed crew fire protection system will function automatically even if vehicle power is disrupted, and will protect vehicle occupants against external pool fire ...

ABSTRACT: An ability to reduce the weight of cables has the potential to provide significant cost savings, reduce maintenance and improve reliability of satellites. The costs of developing and producing satellites are linearly proportional with the satellite"s weight, with each kilogram costing around $1 million when delivery-to-space costs are included. With global satellite launches expected to ...

ABSTRACT: The Department of Defense requires a reliable non-volatile radiation hardened memory for Space and Airborne platform applications. MGRAM, a form of graphene and magnetic memory, promises to satisfy these requirements and to provide a solution path to achieving low cost, high reliability solid state drives for personal computers and systems. MGRAM is based upon a nano scaled bar magnet w ...

ABSTRACT: Cavitation which leads to head falloff and feed system instabilities are a constant source of problems for the low net positive suction head (NPSH) pumps that are needed for advanced liquid rocket engines. Head falloff limits the pumps capability to deliver propellant at the required pressure and cavitation induced instabilities are a significant source of structural failures in rocket ...

In Phase 2, Diffraction LTD, in collaboration with Optics 1, proposes to develop a variable magnification clip-on thermal imager (VM-COTI) that will be compatible with a variety of weapon and head mounted optical systems ranging from 1X night vision goggles (NVGs) to 5X ACOG scopes. The VM-COTI will be a flexible design that can be used as a clip-on fusing full field of view thermal imagery with ...

Low cost and accurate monitoring of sequestered gases such as CO2 is critical to insure that sequestered gases are not reentering the atmosphere. Management requires, in part, improved atmospheric and ground monitoring of greenhouse gases through sensors capable of measuring the flux, concentration and the carbon isotope of CO2 with high accuracy. These Monitoring, Verification and Accounting ...

AlN is an attractive material for power electronics device applications due to its wide bandgap and resulting high electric breakdown field. One of the major challenges that need to be addressed to achieve full utilization of AlN for power electronics applications is the development of a doping strategy for both donors and acceptors. Ion implantation is a particularly attractive approach since it ...

The negative-electron-affinity (NEA) photocathodes which produce polarized electrons are a vital component of electron accelerators such as that at DoE Jefferson Lab and the Stanford Linear Accelerator Center (SLAC). Future systems, such as the International Linear Collider (ILC), will require a polarized electron beam intensity at least 20 times greater than produced by strained GaAs, which is us ...

We are developing a subsurface monitoring technique for providing spatially resolved profiles of soil moisture in the vadose zone that can be easily deployed using either cone penetration testing (CPT) technology, conventional drilling, or in some applications, direct burial. The technology has application to a wide variety of earth and environmental science and infrastructure monitoring challenge ...
