    The rapidly increasing cost of medical care and the contribution of high-technology procedures to that increase are examined. The lack of effective brakes is attributed to the demand for advanced medical care by an aging population and to the fact that third parties-taxpayers and employers-pay 72% of US medical care through Medicare and insurance. Problems also arise because technology is deployed... View full abstract»

    The use of flash memories, which are based on the technology of either erasable programmable ROMs (EPROMs) or electrically erasable programmable ROMs (EEPROMs), as an alternative to both of the latter is discussed. Their properties are compared to those of EPROMs and EEPROMs. Quality and reliability issues are considered. The future of all three memory types is discussed.<> View full abstract»

    A description is given of some advanced spacecraft control applications. The Gamma Ray Observatory (GRO) has decision-making software that gives each of its instruments some discretion as to what it observes, as well as a local area network over which one instrument can alert the rest to a special event. The Hubble Space Telescope, a joint project of NASA and the European Space Agency, relies on a... View full abstract»

    The Southern California Edison Co., the product of some 200 mergers and now one merger away from becoming the largest electric utility in the US, is discussed. The benefits it will reap by its proposed acquisition of San Diego Gas & Electric are examined. The social and regulatory issues the company is facing are addressed. The company's management and R&D are described.<> View full abstract»

    The invention of the dry printer by Chester F. Carlson is briefly described. In 1938 he began the development of a continuous process electrographic printer, a precursor of the Xerox 914, the first production-line automatic office copier, which was introduced in 1959. Carlson approached 20 companies, but not until he met a Battelle Memorial Institute engineer in 1944 did he arouse any real interes... View full abstract»

    The role that will be played by electronics in the automobiles of the 1990s is examined. Automatic traction control, active suspensions, and tire pressure control systems are among the features that will be available. Electronic throttle controls and fuzzy logic controls will be used for automatic transmissions and antilock braking systems. Car buyers' resistance to complex electronic readouts has...
