  • Better networks for test ban monitoring

    From first to last, the conclusion of a comprehensive nuclear test ban treaty has hinged critically on the development of a credible system for detecting explosions and identifying cheaters. Now, with the flowering of seismic networks depending on the digital taking, transmission, and processing of data, such a system appears to be in hand-an achievement all the more remarkable in that the demands on the monitoring system have grown in some ways greater and more complex than ever before. The author describes how, because of the digital revolution in real-time data communication and processing, first-time nuclear tests occurring anywhere on Earth can be promptly identified View full abstract»

  • Electrotechnology cleans up [pollution control measures]

    In ever more ingenious ways, electrotechnologies are being used to detoxify substances from industrial and agricultural waste products and processes, and to clean up land, air, and water. Electric utilities have a particular interest in the new pollution busting technologies partly, of course, because they consume electricity and yet also can yield net energy savings. Just as important, the nature of this kind of expertise widens the range of services a utility can offer its customers. In this dawning era of deregulation and heightened competition, the provision of new services is a key way of gaining and cementing customer loyalty. By taking advantage of the novel electrotechnologies, electric utility customers can improve their product quality, decrease their production costs, and raise their productivity, besides reducing pollutants and energy consumption. If these technologies were to be widely deployed, in effect two million fewer metric tons of volatile organic compounds would be emitted each year in the USA alone, while a million tons of medical waste and 25 million tons of industrial hazardous waste would be rendered harmless View full abstract»

  • The thick an thin of car cabling

    As the number of electronic modules in cars continues to increase, so, too, does the size of the wiring harnesses that interconnect them. These cables not only add weight, increase costs, and complicate troubleshooting of electrical problems-they are also becoming so thick that routing them around a vehicle is by now a real challenge. Here, the author describes how multiplexing many signals onto a single wire will curb motor vehicles' voracious appetite for wire and cable, once standards and volume production take hold View full abstract»

  • Quality enhances reliability [power supplies]

    As deregulation dawns, electric utilities are awakening to the fact that power quality counts with many a customer-and counts for a lot. Even now, the groundwork is being laid worldwide for a new type of service contract between a utility and its large industrial or commercial clients. In brief, the utility promises to supply its customer's operations with power above a certain level of “quality”, and the customer promises to buy power from no-one else for as long as the contract lasts-a valuable concession now that retail wheeling has clients in those categories picking and choosing among suppliers in the electric power industry View full abstract»

  • Earl Masterson: a fresh slant on videorecording

    Both the video cameras and the video cassette recorder-players so popular today use a helical-scan mechanism. This magnetic-tape configuration provides the high data rates necessary for video recording and playback, and solves vexing problems inherent in other options that were intensely studied and developed in the 1950s. The challenge in video recording was to have the recording head move at high speed across the tape surface, yet have the tape move relatively slowly from reel to reel to allow sufficient playing time. In the innovative configuration that turned out to be superior to the other options, the tape winds helically around a cylinder carrying a spinning head, so that closely spaced tracks cross the pickup and recording gaps on a diagonal. This videotape concept originated with Earl Masterson, and here, the author presents an overview of his career View full abstract»
