Traumatic injuries account for 30% of all life years lost in the US and is the leading cause of death for people under 46 years of age. Uncontrolled bleeding or hemorrhage constitute 30-40% of trauma related deaths and are considered to be a major cause o

ABSTRACT: Remote optical detection of ground vibrations could potentially enable discovery of subterranean and camouflaged activity. The basic challenges are to acquire a detailed physical understanding of the detected signal and develop a system at reasonable cost with sensitivity to extremely small fractional light modulations. Under this effort Spectral Sciences, Inc., in collaboration with ...

Adverse physiological events (PEs) have plagued warfighters piloting military aircraft, in particular PEs involving hypoxia and cockpit cabin decompression. Though there has been a large variety of research performed in trying to understand the problems and why theyre caused, there are inefficiencies due to the lack of standardized cross-laboratory protocols, procedures, and metrics. To address th ...

This Small Business Technology Transfer (STTR) Phase I effort will demonstrate the feasibility of using piezoelectric fibers to detect shock waves from underwater explosions (UNDEX) and sensing physiological measures such as heart and respiratory rates on warfighters. Piezoelectric fibers will be characterized for their ability so sense different amplitudes and frequencies of shock and vibration. ...

ABSTRACT: Feature extraction and target recognition suffer from a lack of a reliable model for both exploitable target features and the electromagnetic signature they possess. Signature data are often hard to interpret and invert to recover the target robustly. Bayesian learning approaches to statistical pattern recognition are based on the use of training sets of inputs and outputs, a data mode ...

ABSTRACT: Current and projected limitations on the maximum power from a high power single mode fiber laser amplifier impose architectural limitations on a high power phased array laser weapon system. Prior studies strongly indicate that when faced with this limitation the optimal approach is (to borrow the term for Paul McManamon) a Phased Array of Phased Arrays (PAPA) geometry wherein large(r) ...

The DF&NN team has significant experience in delivering Space Domain Awareness tools. These tools will be applied to 2 years of GEO ephemeris data of active satellites at DF&NN. The RDESB prototype will reduce the risk in rapidly discovering the behavioral patterns of potentially evasive and/or ambiguous active resident space objects. RDESB will detect non-Keplerian behavior in ephemeris data for ...

The computing demands of future data-intensive applications far exceed the capabilities of today’s electronics and cannot be met by isolated improvements in transistor technologies or integrated circuit (IC) architectures alone. Carbon Nanotube Field-Effect Transistors (CNFET) technology has emerged as leading candidate for energy-efficient and high-performance digital systems. Unfortunatel ...

Physical Sciences Inc. (PSI) proposes the development of a composite laminate cathode coating based largely on consumer off the shelf (COTS) industrial materials functionalized to possess a low work function, negative electron affinity surface. The cathode coating is applicable to any surface of a spacecraft, regardless of shape or material, and allows passive one wire operation for spacecraft cha ...

Adaptive optics (AO) system performance is hindered by the mechanical limits of the deformable mirror (DM), namely stroke limits, interactuator stroke limits, and mechanical resonance.The nature of the multi-in multi-out (MIMO) control system does not lend itself well to notch filters to combat the mechanical resonances, and the stroke limits introduce non-linearities to the system.The traditional ...
