Not Available The objective of this proposal is to demonstrate the feasibility of separating cruise missile class targets when there are multiple targets observed by the acoustic sensor. Several programs (e.g., steelrattler, FASDR) have addressed the use of small, remotely deployed acoustic sensors for collecting early warning and rough track on cruise missiles. Typically, the quality of track e ...

Not Available This Small Business Innovation Research Phase I project features as the main goal demonstration of the feasibility of a single-electron transistor with the following characteristics: 1) a high voltage gain, 2) gain over a significant range of operating voltage, and 3) modulation of the current by the gate even if the bias voltage is large. The transistor is an important device main ...

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 DSM is proposing the use of a novel high efficiency AMTEC (Alkali Metal Thermal to Electric Converter) as an increased efficiency power source for space missions and various ground applications. The AMTEC device is very flexible and adapts well to a variety of physical geometries. The proposed system can be easily adjusted and utilized in low earth orbit sensor satellite, or ground ...

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 ...
