"The purpose of this effort is to develop an unattended man-portable or light-mobileRF sensor system to provide ground forces with the capability to detect,intercept, identify, precision locate, and develop targets of both threat voice anddigital communications and non-communications in the millimeter wave frequency radiospectrum. The system will be designed with a wideband scanning capability in ...

"Magnetic field-enhanced electrocatalysis at the hydrogen and air electrodes of PEM fuel cells have reported improved power densities, three-fold over conventional PEMFCs. Leddy, et al. used micron-sized polymer-encapsulated beads of permanent magnetsplaced in conventional inks of carbon-supported platinum electrocatalysts to enhance MEA performance. Their work showed a qualitatively improved CO ...

"On the modern electronic battlefield, a weapon that disables the enemy's electronics can be more useful than a weapon that executes a killing strike. This is possible because a radio frequency (RF) weapon that attacks electronics can be effective over amuch larger radius than a high-explosive (HE) weapon. For example, a single 155-mm artillery shell has a disabling blast radius limited to a few m ...

"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

"Nuclear Weapons Effects Tests (NWET) frequently require that the test article be irradiated in an ultra-clean environment, making survivable shields a necessary part of many debris systems. Survivable shields as large as 12 inches in diameter are requiredbut have yet to be demonstrated in Plasma Radiating Source (PRS) environments. The loads on a survivable shield are a combination of radiation i ...

"Measurements of fluence from a Plasma Radiation Source (PRS) are critical to the performance of accurate Nuclear Weapon Effects (NWE) experiments. Fast, total stopping calorimeters have been demonstrated to provide a robust, reusable, economic sensor forfluence measurements. However, the output of these sensors is a few millivolts and thus high signal to noise recording is difficult to achieve, ...

During this Phase I effort Optomec will demonstrate that the Laser Engineered Net Shaping (LENS) process provides a viable means for both repair and fabrication of functional prototype components for the MPH needs. This work will serve to establish abenchmark part that can be used for calibration and set up of the LENS equipment, as well as other commercially available RP equipment. The goal of ...

"The Army medical community needs a small ruggedized computer for use in combat casualty care and field health support operations. This device must meet the functional needs and requirements of the field medical first responder and be of a rugged naturesufficiently robust to withstand and operate in the severe environmental conditions operationaly encountered. In response to this requirement, Par ...

"Human activity monitoring with a wrist worn instrument, the actigraph, hassuccessfully been used to quantify bulk human activity, and predict macro-quantitiessuch as hr:min of sleep. These devices do not yield information about the underlyingmovement physiology because the simple detection methods ignore important signalcharacteristics. Recently it was demonstrated heart and lung ballistic activ ...
