    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1073 KB)

    A portable microprocessor-based instrument is said to save time and trouble in locating faults in an electrical transmission line. The instrument, which weighs only 35 pounds, sends a swept-frequency signal (made up of waves of various frequencies within a certain range) and then samples the reflections. A few minutes later a graph, indicating the magnitudes and distances of faults down the line, ... View full abstract»

    With this issue Spectrum begins its 20th year of publication. Twenty years may not seem a long time, yet there are readers who were literally in their cribs when Spectrum's first issue went into the mails. We thought it might be interesting to review some of the items that appeared in Spectrum during its first year of publication. View full abstract»

  • Minis and mainframes: More powerful versions of existing systems emerge, as reduced hardware costs encourage parallel-architecture development

    Publication Year: 1983, Page(s):28 - 33

    Each year users become more aware of the high costs of inefficiency and delays in running computer systems that are outpaced by pyramiding workloads — and of the even higher costs when a system goes down. With the growth of computational requirements, the inevitable trend in 1982 in all classes of machines was toward increased speed and throughput. There was strong emphasis on the upward compatibi...

  • Microprocessors: Enhanced general-purpose and number-crunching processors are supported by specialized microcontroller `slaves'

    Publication Year: 1983, Page(s):34 - 35
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (741 KB)

    Microprocessors moved closer to becoming true single-chip mainframe computers in 1982 with the introduction of 16- and 32-bit chips geared to multitasking and virtual memory. At the same time 8- and 16-bit microcomputers and controllers designed as slave processors were introduced. These two developments marked a trend toward distributed intelligence within microcomputer systems, with either centr... View full abstract»

    Personal computers of all shapes, sizes, and prices are springing up as the industry soars beyond $6 billion annually in sales revenue. The introduction of IBM Corp.'s personal computer in 1981 spurred interest last year in the 16-bit personal computer and sparked a price war among the manufacturers of 8-bit computers.

  • Office automation: Most of the pieces of the automated business puzzle now exist, but they have yet to be fitted together

    The slow pace of office automation is not due to a lack of adequate hardware for clerical workers, middle managers, and executives, according to industry observers. Rather, it is caused by the difficulty of putting together workable systems from that hardware. Although software packages exist for word processing, financial planning, and other office tasks, effective turnkey systems to perform all ... View full abstract»

    Integrated circuits grew denser and faster in 1982. The n-channel-MOS 64-K dynamic random-access memory, the new industry benchmark, enjoyed widespread availability. Following close on its heels is the 256-kilobit RAM, due for commercial production in Japan in early 1983. View full abstract»

    Very large-scale integrated circuits available for small instruments have been revolutionizing the way engineers take measurements. The hand-held calculator has relieved them of multiplication and logarithm tasks. The logic analyzer has enabled them to look at the output pins on a chip as computer words rather than as high and low voltages. And instruments introduced last year have been doing more...

  • Design/manufacturing: Integrating CAD with CAM is the major challenge for automating a complete design-to-manufacturing process

    Design automation in 1982 made significant steps away from the electronic drafting board toward more sophisticated aids, with the introduction of products aimed at computer-aided engineering (CAE) for both electrical and mechanical engineers. The products, when coupled with computer-aided manufacturing (CAM) systems, including recent advances in robotic technology, could lead to significant increa... View full abstract»

    Power utilities and manufacturers of energy equipment reached out last year for cheaper and more efficient ways to transmit existing power, even as they pressed their search for fuel substitutes for oil. New efforts began to reap the benefits inherent in dc transmission (more capacity on existing lines) and superconducting cables (less loss of power during transmission). And new protective devices...
