    Issues addressed at three Digital Systems Information Exchange meetings, held in November 1990 and March and September 1991, are summarized. The meetings explored digital developments, looked for areas of actual or potential commonality, and examined possible common frameworks for manipulating digital images. Progress in the area of digital video standards is discussed. The three main standards co... View full abstract»

    A movement aimed at reforming engineering school curricula, called the Synthesis Coalition, is discussed. The coalition is introducing design projects at the outset and weaving math, basic science, engineering science, multidisciplinary, and humanities courses throughout the four-year program. In all, the coalition has some 70 projects in various stages of preparation. Several of them are aimed at... View full abstract»

    Synthesis software for user-programmable logic that relieves designers of complex design fitting, placement, and routing is examined. The program, called a device fitter, manipulates a designer's generic logic description until the best possible fit with a particular field programmable gate array (FPGA) or complex programmable logic device (PLD) is obtained. The characteristics of the newer FPGAs ... View full abstract»

    The development of James Clerk Maxwell's theories on electromagnetism is briefly sketched. By showing that the science of light and optics is merely a branch of electromagnetism, Maxwell achieved the second great unification in physics (the first being Newton's unification of terrestrial and celestial mechanics). The correctness of Maxwell's theory was established only in 1887, eight years after h... View full abstract»

    The nature of bats' acoustic imaging, which combines time and frequency-domain operations in a variety of ways, is discussed. A description is given of a simulated sonar receiver based on the brown bat's auditory system. Algorithms that mix time and frequency-domain techniques to reconstruct target shape from echoes have been tested successfully in a computer, and work is in progress to develop a ...

    Programs of the US Commerce Department's Technology Administration that are stressing cooperation with industry and academia are discussed. As a result, Commerce programs reflect different approaches. In some cases, the department acts as an advocate for industry within the Federal government. The Commerce Department also acts as an advocate for industry with foreign governments. Efforts are under... View full abstract»
