Not Available The goal of this Phase I research is to design, fabricate, and test a high-efficiency, low-power, two-phase pumped loop. This high-efficiency, low-power, two-phase pumped loop will use a unique two-phase working fluid pair that offers the capability of higher efficiency and lower pumping power because of its heat of solution characteristic. This heat of solution characteristic, comb ...

Not Available Proposed is the development of a novel magnetic field sensor comprised of two smart materials: piezoelectric ceramics, and magnetostrictive materials. Similar to a bi-metallic strip, this sensor consists of a thin beam of a substrate material with a thin wafer of piezoelectric material bonded to one side, and a thin wafer of magnetostrictive material bonded to the other. When the ...

Not Available Advances in optical computing and signal processing would benefit from the breakthroughs in materials technology for monolithic optoelectronics integration. We propose a new silicon-based light emitter for such possible superchip-IC . This concept is an extension of a major material development recently demonstrated called hetero-epilattice Si/O superlattice (HES), which for the ...

Not Available This Small Business Innovative Research Phase I project will develop a system that provides a positive indication to the catapult officer when an aircraft launch bar is properly seated in the catapult shuttle of an aircraft carrier. Improper launch bar seating has resulted in the loss of numerous aircraft. The proposed system will employ a two dimensional machine vision system based ...

Not Available SunPower proposes a high-efficiency, radiation-tolerant, thin silicon photovoltaic cell for space power generation. Compared to competing III-V (GaAs) photovoltaic cells, this cell is expected to provide nearly equivalent output power at about one-quarter of the cost. Based on preliminary simulations, we expect that the cell will achieve 18.8% beginning-of-life (BOL) AMO efficienc ...

Not Available LightPointe Communications, Inc. proposes to combine the advantages of license free wireless laser-and RF-technologies and built an ultra high speed variable data rate microwave digital radio (MDR) inteface as backup system for terrestial laser communication links. The digital radio interface will be capable to operate at speeds up to 155 Mbps which will be the highest data rate ev ...

Not Available Mission Research Corporation (MRC) proposes to develop and demonstrate a solution to the single event effects (SEE) problems which result in data loss in deep submicron microcircuits used in space environments. We describe a unique hardening technique, which we refer to as a temporally redundant latch. This approach provides immunity to SEE related upset effects with a minimal i ...

Not Available One of the open research issues in the incorporation of battlefield stressors into CGF technology, involves the interaction of the external stressors with the personality characteristics of the individual war fighter. Further complicating this issue is the fact that the personality traits of an individual are influenced by the personality traits and the actions of other individuals ...

Not Available Traditionally two methods have been applied to terrain rendering: 1. Cell-based rendering of pre-computed, decimated levels of detail (LOD), and 2. Real-time creation of a terrain skin with continuous LOD whereby only required polygons are drawn based on distance from eye-point. The objective of this research is to investigate a terrain rendering technique that combines benefits of ...

Not Available The Phase I program proposed will demonstrate the feasibility of using shearography to rapidly and effectively inspect the Navy's multi-layered composite core structures for critical defects that effect the integrity and/or performance of these structures. These advanced composite structures are used on ship board for superstructures and hulls, as well as for primary structure on na ...
