The fabrication of microelectronic components is a critical capability for both the national defense and economic security of the United States. Inspection processes are crucial in the fabrication of these components, assuring the economical production of high quality, state-of-the-art components. Current inspection processes for subminiature electronic assemblies typically rely on a single sens ...

Parallel computers have been available for several years but have yet to fulfill their promise despite the potential for greater scalability and lower cost/performance. While interest in parallel computing systems remains high, widespread proliferation of these systems has not occurred. The basic problem facing MPP users is lack of portable and scalable programming systems and libraries and portab ...

Parallel computers have been widely available for several years but have yet to fulfill their promise despite the potential for greater scalability and lower cost/performance. While interest in parallel computing systems remains high, widespread proliferation and acceptance of these systems has not occurred.

The miniaturization of the laser diode, power switches (MCT, IGBT, etc.), the drastic increase in the number density of transistors on a monolithic chip and the capability to drive these chips at very high power ratings and clock speeds has increased the demand for the devices. However, such high performance can be extracted only over short time pulses because the devices produce a moderate amoun ...

Lanxide Corporation proposes to demonstrate the feasibility of utilizing the active brazing method to join a Nicalon TM fiber reinforced alumina matrix composite to structural alloys for applications i advanced turbine engines. The high temperature capability of the ceramic matrix composite allows uncooled operation of several turbine engine components resulting in significant gains in specific fu ...

The purpose of this proposed SBIR Phase I effort is to evaluate the technical and economic potential for Active Matrix Electrouminescent (AMEL) display technology in miliatry and commercial applications. This work will focus on evaluating the potential for high resolution miniature Head-Mounted Displays (HMDs) and larger active area displays for Persona Digitial lAssistant (PDA) applications. Th ...

AstroPower proposes to develop gallium phosphide (GaP) ultraviolet (UV) sensors for engine combustion control. The UV spectra from the free radial combustion components correlates with combustion effectivity in terms of predetonation, and provides a real time basis for central control of excess air ratio, internal combustion temperatures, and other fuel injector parameters. A system for the engine ...

Several benefits result from variable-speed capability in mobile engine generators with high frequency alternators ("HFAs") and power frequency converters ("PFCs"). The two primary benefits are increased power through higher engine speeds and increased efficiency through use of the optimal speed in tracking loads. The variable-speed units now available indicate that substantial improvements are ...
