    The use of lasers, cameras, and advanced signal processing to help isolate individual offenders on crowded highways is discussed. The limitations of the predominant radar in use today, namely down-the-road Doppler-radar in which the axis of the antenna is directed along the line of travel of the target vehicle, are described. The potential of video records, across-the-road radar, and both across a... View full abstract»

    The knowledge of the wavelike behavior of electrons that emerges as technology drives semiconductor geometries deeper into the nanometer domain is described. How the underlying size quantization effects restrict the scaling down of device dimensions is explained. Studies underway to explore and understand these phenomena are reviewed. Ways in which they can be exploited in new types of device are ... View full abstract»

    A broadcast ghost-canceling reference signal that will enable digital signal-processing circuits in TV sets to erase multipath distortions is discussed. A typical receiver ghost-canceling system, consisting essentially of a channel identifier and ghost-canceling filters, is described. Factors affecting the choice of a ghost-canceling reference (GCR) signal as a standard are examined. Results of fi... View full abstract»
