The leading risk facing our soldiers in Iraq is an improvised explosive device (IED). IED attacks on vehicles create an extreme shock environment that has been linked to Traumatic Brain Injury (TBI). While the damage mechanisms that cause TBI remain elusive, several researchers have speculated that the damage mechanisms of stress and strain associated with non-war-related TBI may not sufficiently ...

The pioneering efforts within the DARPA SENSIT and NEST programs, proved the potential of wireless sensor network (WSN) technology for compelling DoD applications, including surveillance and target localization. These projects'' legacies include hardware platforms, used extensively in academic research today and the TinyOS software suite. At the same time, these programs revealed the limitations o ...

Multi-core processors pose a significant challenge for software application developers. This is because the vast majority of algorithms and applications have been - and continue to be - developed using methodologies and techniques that assume sequential runtime execution. The key to efficiently and effectively leveraging multi-core processors is the ability to expose, extract, and exploit concurr ...

Chlorine gas was first used as a weapon during World War I and has reemerged as a threat in Iraq compounding the dangers from existing improvised explosive devices. One of the significant challenges with preventing attacks that involve toxic industrial chemicals (TICs) like chlorine, ammonia is that they have genuine civilian uses for water treatment, in refrigeration systems, and others, that m ...

Military imaging optics, such as rifle scopes, spotter scopes, and optics found on unmanned vehicles could be substantially better if the mechanical movement of optics for focus and zoom could be eliminated, without creating new problems associated with the rugged and harsh environment. The technology of liquid lenses has surfaced as a possible solution, but these lenses have problems with enviro ...

We provide a novel approach to realizing negative index lenses and lenslet arrays at optical frequencies using a naturally occurring material such as cis-vitamin A, a constituent in some commercially available cod-liver oils. This form of vitamin A has been recently found in the eyes of lobsters and hypothesized to be responsible for negative index lensing in their superposition eyes. The propos ...

This proposal presents a feasibility study and design of a small high temperature superconducting (HTS) antenna employing SQUIDs (Superconducting Quantum Interference Devices) technology that serve to target origination of RF energy and therefore provide accurate direction finding in a dense interference environment. The technical objectives are to design a HTS antenna that employs Josephson Junct ...

The Nutating Disk Engine is a new technology with significant advantages, and multiple potential military and commercial applications. Development work has focused on a dual-disk version of the engine, including a demonstrator prototype. Second-generation prototype is currently in development. This DARPA program provides an opportunity design a single-disk version. Development work to date has ...

Reliable sample preparation from a variety of complex matrices remains one of the most challenging problems facing biological detection in the field. This is especially true for isolation of nucleic acids from an environmental or clinical sample. A clean nucleic acid sample, free from contaminating materials such as cell debris, dirt and inhibitory chemicals, is required to ensure the robust perfo ...

In today’s dense electromagnetic environment, proper allocation and management of spectrum is an overriding concern for US military forces. The migration to higher microwave and millimeter-wave frequencies has made much needed bandwidth available for military radar and communications. This migration, however, has also highlighted the need for high-performance filtering to mitigate jamming and ...
