A program is proposed which will inhance the eficiency of key thermo-photovoltaic (TPV) components and significantly lower their cost. A new process for fabricating resonant mesh filters will simplify and lower the cost of their manufacture. Thefeasibility of a new tandem filter will be explored. If successful, this tandem filter would increase the TPV system efficiency by about 38%. We also p ...

This proposal focuses on the design and realization of a Rapid Development Environment (RDE) for synthesizing Physiological Diagnostic Systems. A high level of productivity will be reached through the development of libraries of sensors, and of elementaryand complex physiology models. The user will compose a diagnostic algorithm and system prototype by combining building blocks thorough an intelli ...

A Diesel driven high efficiency, portable thermoelectric generator capable of producing 500 Watts, scalable to 1500 Watts will be designed at Hi-Z Technology. The unit will supply uninterruptible power at 28 VDC for a minimum of 8 hours. The generatorwill be capable of starting and operating from -32 oC to + 52 oC. The unit system efficiency will be over 10%, it will exhibit a suppressed infrar ...

JX Crystals presently fabricates infrared sensitive photovoltaic cells under license from Boeing. Also, on a recent Army/DARPA contract, JX Crystals fabricated a custom liquid fuel burner for use in a TPV power source. Herein, we propose to design a 500Watt TPV power source around a commercially available industrial recuperative silicon carbide radiant tube burner capable of operating with an in ...

The Phase I effort produced the designs and sample items for six measures of cognitive skills necessary for effective small unit leadership. The primary objectives of the proposed Phase II effort are to develop further these five measures, including thecomputer simulation, to validate the assessment battery, and to develop and validate a business version of the 2 leadership measures. The last ob ...

An efficient thermophotovoltaic system that is cost-effective, light weight, and mechanically robust is proposed. The high efficiency is achieved by employing a silicon cell array illuminated by a ytterbium oxide emitter along with a high degree ofthermal recuperation from a thermally stress tolerant ceramic regenerator.A burner, power by aerosolized or atomized logistic fuels, rapidly mixes the ...

The nutritional health of field personnel deployed for extended periods is a long-standing problem critical to military troop performance and readiness. The combination of extraordinary physical stresses and the limited provisions carried by militaryfield personnel result in large caloric imbalances. Personnel may experience: loss of strength and decreased endurance; loss of motivation and decr ...

Accurate usage information collected by Health and Usage Monitoring Systems (HUMS) coupled with improved structural fatigue life calculation methodologies promise to reduce helicopter operational and support costs while maintaining current flight safetylevels. Current fatigue life calculations assume worst-case flight profiles in determining component life. This approach may be outdated or not r ...
