    Concentrating the computational power of a multimedia desktop or laptop computer into a central processing unit only slightly larger than a hand-held organizer, wearable PCs are finding plenty of users in the commercial world. What wearable computers have to offer is job-critical information to people whose hands must be free for other work. Assembly line workers, for example, can access a databas... View full abstract»

    Wouldn't it be a lot easier to read a laptop's screen if the words looked as if they were printed on paper, as in a newspaper or magazine? Well, that is the case for a trio of unique displays about to hit the market. Of the three new displays, the closest to hitting the market is a liquid-crystal display (LCD) from Kent Displays Inc., Kent, Ohio. Called cholesteric because the liquid-crystal mater...

    As demand for high-frequency communications mushrooms, indium phosphide technology has emerged as a leading candidate for chips to meet that need. Already InP ICs with thousands of transistors are reaching speeds of over 65 GHz. The necessary level of complexity and speed is available from HBT ICs built on indium phosphide substrates using materials with different energy bandgaps for the emitter, ... View full abstract»

    Third-generation cellular telephony is on its way-not, unfortunately, as a single worldwide system, but as three incompatible ones. The main difference between the three lies in their choice of radio interface technology. This fact is crucial for several reasons, since the radio interface determines not only the fundamental capacity of a mobile radio network, but also how it deals with such issues...

    To meet the demands of designing and running far more complex and highly integrated electricity systems, a new kind of power engineer is needed. In this paper, the author describes how, though students tend to favor higher-tech and more lucrative fields than power engineering, reports of the discipline's demise are exaggerated.
