ACX proposes to develop durable and reliable conformal geometry actuator packages. These packages will have the ability to operate as linear actuators for motion control applications as well as to conform to structures with curved surfaces for applications requiring induced strain actuation. These packages provide a protective skin offering electrical isolation, and provide a means for integration ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

The XA2 gasoline burner is widely used by the military to meet a variety of food preparation and heating requirements in the field. Because of the trend toward an single-fuel Army vehicle fleet and away from gasoline as a general purpose fuel, a diesel/JPS fueled burner is sorely needed. A recently developed catalytic vapor generator together with the proposed metal-hydride preheater should prov ...

Silicon avalanche photodiodes are among the most sensitive optical detectors available today. It 11as been shown that large area APDs are potentially an excellent alternative to photomultiplier tubes (PMTs) in applications such as LIDAR, nuclear medicine, physics research and nuclear radiation measurement instrumentation. They can offer improved performance based on their compact size, solid state ...

Network surveys hold great promise for information and data gathering, and would allow almost instantaneous access to large and diverse populations. Although there is a mature literature on survey methodology in other media, little is known about how networks might interact with survey processes or impact response accuracy. ALPHATECH proposes to analyze existing survey literature to identify cri ...

Current production ladar system and components involve coherent optical system using pulse waveform. "bile demonstrating impressive accuracy and resolution, the system are coupler, difficult to manufacture, and thereby erpensive. An alternative approach is being investigated for short range system which uses an FM/CW waveform for ranging with incoherent light detection. This approach should prod ...

Unmanned Aerial Vehicles (UAVs) offer a lower risk and lower cost platform for the use of an Ultra Wide Band (UWE) Synthetic Aperture Radar (SAR) system for the detection of ground targets concealed by foliage. Given the size, weight, and power restrictions of a UAV, an impulse radar is an attractive radar system alternative because it offers a lighter and lower cost solution than a traditional c ...

The main thrust of this proposed effort is to design, develop, and fabricate a low cost, producible, robust and rugged, one pixel, range-only laser radar (Ladar) fuze sensor sufficient to support the safe and reliable delivery of a ballistic round against an intended target. A CW/FW waveform is planned for use to amplitude modulate the laser diode transmitter. The returned optical energy will be ...

New power semiconductor device performance is limited by cooling because high heat-flux cooling systems have not matched their increased power density. Therefore, real designs rarely achieve device ratings. American Superconductor (ASC) demonstrated CryoPower+, which cools a variety of power MOSFET topologies by direct immersion in coolants from 77-300K, with boiling where appropriate. CryoPower ( ...
