  • Ballistic-missile defense radars

    Publication Year: 1970, Page(s):32 - 41
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (7291 KB)

    Ballistic-missile defense has been continuously researched in the United States for the past 14 years. The Safeguard system itself is an outgrowth of both the Nike¿Zeus system and later ballistic-missile components developed by various government agencies. The classic result of this early work was clear¿an ICBM could be intercepted by another missile. Hence, the real controversy concerning the w... View full abstract»

    The means for providing underground transmission of large quantities of electric power at a reduction in present-day cost by at least an order of magnitude ranks among the high imperatives of today's research efforts. Demand for the expansion of ``undergrounding'' is soundly based upon such factors as the rapid growth of cities, the doubling of power requirements with every passing decade, and est...

  • The low-power-drain microelectronic VHF amplifier

    Publication Year: 1970, Page(s):49 - 53
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3506 KB)

    Low-power-drain VHF amplifiers have some unique characteristics when they are miniaturized. And, if the design is special¿requiring tight tolerances or intended for limited-quantity production¿it is often desirable to make the RF micropower circuits from discrete components. Described in this article are the first-order device requirements and circuit considerations for such VHF amplifiers incor... View full abstract»

    Within the walls of the Burndy Library, one has access to 30 000 printed volumes, and, in addition, rare manuscripts, correspondence, and laboratory notes written over the centuries by many of the world's greatest scientists, engineers, inventors, physicians, and philosophers. More than 300 of the science ``incunabula'' (books published in the first 45 years of printing, 1455-1500) are included in... View full abstract»

    Analytical and experimental studies seeking to confirm or refute the hypothesis that moths communicate with each other by coherent electromagnetic waves have been under way at Berkeley for several years. This article is the first report from the bioengineering group conducting these studies. View full abstract»

    A brief discussion of the basic elements of data communication systems and a review of the current state of the art provide a prelude to the main theme of this article¿a description of two inventions in this field by the writer. One is a data communication system; one a conversational information-processing system. View full abstract»
