    Viewers of the CBS Television News show ¿60 minutes¿ were treated recently to a segment describing the U.S. businessman's plight in keeping up with the proliferating paperwork required by Government regulations. Several points were made: Federal agencies often require the same data, presented independently and in different formats; Federal, state, and regional governments require similar data, p...

  • Circuit techniques: Enhancing MOS/LSI's role in analog design: High-density amplifiers, A/D and D/A converters, filters, and coder-decoder circuits can now be fabricated

    Publication Year: 1979, Page(s):24 - 32
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1750 KB)

    Discusses design approaches that combine analog and digital functions on one MOS LSI chip thus lowering the cost and size and improving the reliability of such circuits as linear amplifiers A/D and D/A converters, and precision frequency filters. Instead of the conventional multichip and hybrid designs, analog circuits are fabricated with the same high-density MOS/LSI processes employed for such s... View full abstract»

  • Memories: An optical disk replaces 25 mag tapes: This 30-cm disk features a long-life tellurium film upon which data is impressed by laser

    This 30-cm disk features a long-life tellurium film upon which data is impressed by laser. No processing of the optical disk is required, and a shelf life of ten years is indicated. The optical system is designed to check the recorded data instantly and to rerecord at once any part of the disk where discrepancies appear. Such a disk was developed experimentally for the Philips DRAW (Direct Read Af... View full abstract»

    Discusses the 1950s to 1970s experiences with the use of off-peak electricity, taking into account both the residential and industrial users. Devices available in late 1970s to consumers in Britain are discussed. These include radiators, fan heaters, systems with ducting, floor-warming cables and water heaters. View full abstract»

    Discusses the second-generation train control systems which include automatic train supervision, using wayside central computers for integrating and stabilising the overall system. Other features include the use of wideband, bidirectional communication links which allow `moving', rather than fixed, block control, thereby reducing headways and providing safe, closed-loop control. Several systems op... View full abstract»

  • Innovation: Thomas Edison and his electric lighting system: The inventor's notebooks reveal that he was actually a skilled practitioner of systems engineering, not the tinkerer of legend

    Over the past century no one has better exemplified the image of the heroic inventor than Thomas Alva Edison. What was popularly understood as his ¿cut and try¿ approach to invention gave rise to the most prolific inventive career in American history, earned for him the title ¿the Wizard of Menlo Park¿ and a place in American folklore. Such imagery, however, is the unfortunate result of much m... View full abstract»
