    Even today, antitechnology enthusiasts drive their air-poluting vehicles to convocations where they decry the very acts they themselves perform. They burn the midnight oil while suggesting that citizens grind their own coffee beans by hand - by legal edict if they will not comply voluntarily. Exaggerated? Of course. Yet a breed of environmentalist exists that is readily visualized through such a c... View full abstract»

  • Retrospective: The $100 idea: How Russell and Sigurd Varian, with the help of William Hansen and a $100 appropriation, invented the klystron

    Publication Year: 1975, Page(s):30 - 39

    I first met Russell Varian in 1939 on a stairway landing in the Stanford University Physics Building. I had just been hired as a part-time research associate on the new Klystron Project at a then munificent $90 per month, and was going upstairs to meet the Varians and their small staff. I had heard of the invention of this new electron tube that could generate centimeter waves, but I did not know ... View full abstract»

  • Instrumentation LEDs: Digital domination? Light-emitting diodes proliferate as gas-discharge and liquid-crystal digital readouts find special niches

    Publication Year: 1975, Page(s):40 - 42
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (777 KB)

    Only five years ago, few visible light-emittng-diode (LED) devices were used as instrument displays, and liquid-crystal displays were largely a laboratory curiosity. Gas-discharge, fluorescent, and incandescent readouts constituted the majority of instrument display devices then. Today, the venerable ¿Nixie¿ tube, the prototypical gas-discharge device, is still in use. And its successors continu... View full abstract»

  • Transportation: Fixing BART: A "million-dollar" backup for the automatic train protection system stems from BART's "Blue Ribbon Panel" report

    Publication Year: 1975, Page(s):43 - 45
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (619 KB)

    Depending on who you talk to, the BART saga thus far is seen either as a tragedy or, at best, a mock epic. Avid Spectrum readers have followed the chronicle from design and development to the surprise accident of October 2, 1972, when a crystal oscillator in the automatic train operating (ATO) subsystem transmitted the wrong speed command and a BART train overran the Fremont station, plowing into ...

  • Instrumentation generating speech spectrograms optically: Coherent optics speeds analysis of speech samples; it's five times faster than older methods

    Publication Year: 1975, Page(s):51 - 56
    Cited by:  Papers (2)

    The optical technique used in the speech spectrogram generator described here permits the analysis of signals having frequency components within the ultrasonic or very-low-frequency ranges, and the system is capable of examining large amounts of data continuously throughout the processing.

  • Management planning is for people: Painful, yet educational, surprises greet the engineering planner as he takes his ideas to the public

    The long-range telephone planner is responsible for formulating the plans for expanded facilities, and for helping to obtain governmental permission to build them. In New York City, for instance, planning engineers responsible for telephone exchange buildings must get a variance-to-build from the New York Board of Standards and Appeals (BS&A). They are also required to inform all home owners w... View full abstract»

    In an important action, the IEEE Board of Directors adopted an IEEE Code of Ethics for Engineers at its meeting of December 4, 1974. The new code resulted from the combined efforts of a number of volunteer Committees and Boards within IEEE, specifically the United States Activities Board (USAB), USAB's Ethics and Employment Practices Committee, the Executive Committee and its ad hoc Committee on E...
