Future manufacturing of integrated circuits (IC's), will require analytical instrumentation that can provide on-line process monitoring linked to real time process control. Fourier Transform Infrared (FT-IR) spectroscopy can be effectively utilized to meet this need. As an example, Advanced Fuel Research, Inc. (AFR) has successfully employed simultaneous FT-IR reflection and emission spectroscopy ...

The objective of this research is to design a micromechanical temperature sensor capable of recording temperature extremes experienced beyond a preset value without the use of electrical power. The temperature sensor's memory will be mechanically induced. The sensor will be either in an electronically resettable form, or, less expensively, in a disposable form. The proposed device will be microfab ...

Plasma assisted processing techniques are widely used in many industries to synthesize materials at low process temperatures. Stringent precision requirements for devices and the demand for low cost manufacturing techniques emphasize the need for optimizing plasma reactors. Numerical simulation offers a quick and inexpensive alternative/supplement (to hardware experimentation) for designing new an ...

Dynetics proposes an innovative combination of analog and digital technology to produce a Lock-In Acousto-Optic correlator for application in pulse-coupled neural networks. Our unique approach uses a time-integrating optical correlator and high-speed, two-dimensional digital processing for matched filtering of repetitious waveforms of unknown pulse repetition frequency (PRF). Dynetics' proposed ap ...

The next generation of tactical missiles will use several types of non-traditional propulsion systems, each of which requires a control system. A method is required to economically and thoroughly evaluate and analyze the propulsion control system without risking expernsive, one-of-a-kind, prototype propulsion systems. Electronic Concepts and Engineering Inc. proposes to develop a real-time simula ...

Fast Fourier transformers (FFFs) are used extensively in military and commercial applications. There is a constant demand for faster and more accurate FFTS. RNS (Residue Number System) based FFTs are candidates to provide these improvements, however techniques for efficient implementation of RNS operations must first be developed. RNS operations will be develope in the proposed Phase I research th ...

A power controller is described which has increased power capability (50-100 Hp range), improved efficiency, reduced cost, and increased control capability for control of onboard auxillary power sources. A full four-quadrant control inverter uses a variable frequency, quasi-resonant four-quadrant H-bridge configuration and a phase shifted PWM controller for control of a three phase AC induction mo ...
