The production of semi-conductor wafers is a multibillion dollar industry. The 1996 worldwide semiconductor market is estimated at $162 billion with a growth potential to $309 billion by the year 2000. Thus, even a small improvement in control during the manufacturing process could have a large impact on the economic viability of many companies and products. A critical factor in all semiconduct ...

A novel approach for controlling weld bead penetration is proposed. The methodology is distinguished from past techniques by use of: 1) a new and more accurate model of the weld pool dynamic behavior, 2) an improved method of sensing the weld pool oscillations, 3) a more efficient method of weld pool excitation, and 4) a model-based relation of pool dynamics, weld pool geometry, and equipment para ...

Systems & Processes Engineering Corporation (SPEC) proposes to develop a Waveform Agile Signal Processor (WASP) to support the next generation of fuzing systems and subsystems. WASP is designed to~provide high performance, waveform agile, adaptive signal processing for a variety of RF and optical fuze sensors. WASP is designed to support pulsed time domain, frequency domain, phase, direct sequen ...

SCHMIDT INSTRUMENTS PROPOSES TO DEVELOP A NOVEL TUNABLE PHOTODETECTOR BASED ON A DOUBLE BARRIER PHOTON ASSISTED RESONANT TUNNELING STRUCTURE. THE DEVICE CAN BE FABRICATED FROM A NUMBER OF SEMICONDUCTOR SYSTEMS DEPENDING ON THE DETECTOR CHARACTERISTICS ONE DESIRES. FOR EXAMPLE, A DETECTOR BASED ON THE GAAS/ALGAAS SYSTEM WOULD BE CAPABLE OF DETECTING PHOTONS WITH ENERGIES THROUGHOUT THE INFRARED SPE ...

The Virtual Environment Training for Battlefield Medical Personnel (VETBMP) project is the development of a simulation architecture designed to integrate procedural simulations, intelligent tutoring, and various sensory input devices to create a realistic training scenario for 'forward' military personnel. Phase I of VETBMP will be a simulation of a standard medic task (intravenous infusion), emb ...

The global and persistent coverage from space requires an effective integration across multiple proliferated satellite constellations. The primary challenge in using low-Earth orbit for global sensing and communication is the sheer size of the constellations that are necessary for total coverage. Building the required number of spacecraft and the corresponding payloads within schedule and cost tar ...

THE OBJECTIVE IS TO DEVELOP COMPUTER SOFTWARE WHICH ANALYZES THE OPERATIONAL HISTORY OF ARMY VEHICLES, SUCH AS 5-TON DIESEL TRUCKS, AND BASED ON THIS ANALYSIS RECOMMENDS MAINTENANCE AND OTHER PREVENTIVE ACTION WHICH MINIMIZES EQUIPMENT BREAKDOWN. THE SOFTWARE WOULD OPERATE ON A PRIME COMPUTER, AND IT SHOULD INCLUDE EXTENSIVE GRAPHICS CAPABILITIES WHICH WOULD ASSIST IN PROGNOSTIC ANALYSIS. THE SOFT ...

The primary objective of the proposed investigation is to develop numerical tools capable of producing scalable algorithms for efficient solution of a general class of large geophysical inverse problem in a massively parallel processing (MPP) computing environment. An example problem is the rigorous solution of the Earth's gravity field using massive satellite data. Currently, such a solution can ...

ENGIN-IC, Inc. proposes a Phase I study to develop an innovative wafer-scale phased array antenna to support the requirement for V-band transmit, SATCOM downlinks. Given the constrains of maximum element to element spacing that is governed by fundamental laws of physics, the phased array antenna will require wafer scale packaging. By utilizing innovate chip-on-chip and chip-on-substrate technology ...
