    Just six days before Voyager 2's closest approach to Uranus, in 1985, compressed photographic images transmitted from the spacecraft's cameras began to include large blocks of black-and-white lines. Engineers at the Jet Propulsion Laboratory, Pasadena, Calif., ran an old data stream received from the craft through the programs used to decompress the images back on earth. View full abstract»

    If engineers could agree on and use a professional title that would be accepted globally, they might better serve the public and have more political influence. So begins a recent letter to the editor of Civil Engineering magazine. Similar communiques appear from time to time in many other professional engineering journals, and they usually evoke in me a flickering of interest and agreement. View full abstract»

    For well over 10 years it has been known that oscillating magnetic fields, if allowed to penetrate the body, can cause physiological changes that stimulate bone growth. Since the mid-1970s the pulsed electromagnetic field (PEMF) has been used to heal fractures that otherwise refuse to knit, with success in almost 100 000 patients. The PEMF machinery is bulky and power-hungry, however, and if a lar... View full abstract»

    Is company loyalty a thing of the past? To what extent is it important, anyway? Can engineers and scientists whose jobs are linked to specific projects have great loyalty to the corporation when a project cancellation or a corporate merger might leave them unemployed? Can top executives whose jobs hinge on the quarterly report to stockholders be expected to have great loyalty to the corporation, i... View full abstract»

  • Next-generation race bogs down: Japan, the United States, and Europe are still far from their declared goals for ‘intelligent’ machines, but Japan's hidden Agenda may already have succeeded

    A reassessment of the goals of Japan's Fifth-Generation Computer Project (ICOT) is presented and the progress examined. Expert evaluations of the project's accomplishment are seen to vary widely, and the quality of the research is likewise regarded as mixed. Related Japanese research outside the project is also discussed. Competing efforts in the US and Europe are described, and the results of the... View full abstract»

  • Oscilloscopes: How to find the one that fits: New options, from scopes on PC cards to Glitch detection, may at first bewilder users — But will ultimately help in matching instruments to applications as never before

    The characteristics of the many oscilloscopes available are examined in the context of selecting an instrument for a particular application. The discussion covers performance, automatic setup, menus, digital storage, and instruments for fast single shots. Cost is considered. What the oscilloscope is to be used for generally determines the choice of instrument. View full abstract»

    Digital signal processors are defined, and the characteristics that must be considered by the engineer are discussed. The architectural features of the processors are examined, with an emphasis on the multiplier-accumulator, which is considered one of the most important features. Single and multiprocessor operations are discussed, and the pitfalls in using benchmark performance figures are examine... View full abstract»

    The importance of taking human factors into account early in the design process is discussed and illustrated by examples in which they were not considered. The history of human factors as a subject of study is related, and various issues that must be addressed, e.g. the impact of computers or the characteristics of the operator, are examined. The role of simulation in human-factors-based design is... View full abstract»

    On an overcast Sunday in January, a group of Fairchild employees took the Clipper, a 40-foot racing sloop, for an outing in San Francisco Bay. Silver-haired Howard Sachs, vice president and general manager of the Fairchild Advanced Processor Division, sat at the tiller and gave the orders. After all, it was his boat. View full abstract»
