No one questions the philosophy that it is better to avoid industrial pollutionrather than to attempt the clean up of an environmentally abused site.Unfortunately, we are slow to learn this lesson and hazardous wastes become moreexotic and continue to increase. Causing 21 of the 28 EPA superfund sites in theSilicon Valley (Witkowski and Menon 1991), the semiconductor industry was, andcontinues to ...

Insulated gate bipolar transistors (IGBT) represent the standard component in converters for electric vehicles and motor control. However, they are a mature technology where only marginal performance improvements can be expected, and improvements in IGBT based converter efficiency can only reflect these incremental improvements. MOSFET controlled thyristors (MCTs) represent a new class of power s ...

Industrial wastewater containing toxic waste compound and metal ions pose manyproblems of disposal. The most generally used method of removing metalcontaminants is lime treatment to precipitate metals as hydroxides. The metalis not normally recovered resulting in the need for sludge disposal. The costof sludge disposal plus fewer available disposal sites makes that methodincreasing less attract ...

Hexavalent chromium, Cr(VI), in the usual form of oxo species, is used in manyindustrial processes and products. As a consequence, Cr(VI)= containingcompounds are often found in wastewater and contaminated sites. Since Cr(VI) isconsidered highly toxic and carcinogenic, it is extremely important to have areliable, easy-to-use, sensitive monitor for determining Cr(VI) concentrationsin process, on ...

Production products will develop a non-invasive communication/sensor system for monitoring structural health real-time using embedded sensors in composite structures. We will use advanced composite structure, joining and sensor technology from our mentor/protege partner on this program, McDonnell Douglas Corp. (MDC). We will focus on cylindrical members which form the basic building block elements ...

It is the purpose of this proposal to develop the key technologies required to construct a man-portable advanced multimedia imaging helmet system. We will develop and demonstrate three helmet designs including a monocle headset, a goggle headset, and a face plate. These three helmet platforms will be founded on the miniaturized CPU, communications, display, audio, and sensor technologies establis ...
