30、en speaking into a smalI badge worn on the chest. What sets the comm badge apart from a mere walkie-talkie, and appeals to Star Trek fans, is the system s apparent inte11igence. It works out who you are calling from spoken commands, and connects you instantly.The system, developed by Vocera Communic

31、ations of Cupertino, California, uses a combination of Wi-Fi wireless networking and Voice-overInternet Protocol (VoIP) technologies to I ink up the badges via a central server, akin to a switchboard. The badges are al ready being used in 80 large institutions, most of them hospitaIs, to replace ove

32、rhead paging systems, says Brent Lang, Vocera s vice-president.Like its science-f iction counterpart, the badge is designed so that al I functions can be carded out by pressing a single button. On pressing it, the cal ler gives a command and specifies the name of a person or group of people, such as

33、 cal I Dr. Smithw or locate the nearest anesthesiIogistn. Voice-recognition software interprets the commands and Iocates the appropriate person or group, based on whichever Wi-Fi base-station they are cIosest to. The person recei ving the caI I then hears an audible alert stating the name of the cal

34、 ler and, if he or she wishes to take the call, responds by tapping the badge and starting to speak.That high Iights a key difference between the Star Trek comm badge and the real-1ife version: Vocera s i mpIementat i on a I Iows peopIe to reject i ncom i ng calls, rather than having the voice of th

But even the most purist fans can forgive Vocera for deviating from the script in this way, says David Batchelor, an astrophysicist and HStar TrekM enthusiast at NASA s Goddard Space Fl ight Center in Greenbelt, Maryland. For there are, he notes, some curio

36、us aspects to the behavior of the comm badges in “Star Trek. When the captain of the Enterprise says “Picard to sick-bay: MedicaI emergency on the bridge”, for examp I e, his badge somehow connects him to the sick-bay before he has stated the destination of the call.Al lowing badge users to reject i

But in almost al I other respects the badges work just I ike thei r fictional counterparts. This is not very surpr ising, says Lawrence Krauss, an astrophysicist

40、an opportunity to boost thei r sales with high-tech products. You could cal I it the revenge of the nerds: a new wave of microchip-equipped sporting goods promises to enhance the performance of novices and non-sporting types alike-and could even make difficult sports easier.Take cross-country ski in

Victor Petrenko, an engineer at Dartmouth Col lege* s Ice Research Lab in New Hampshi re, has invented some smart ski-brakes that, he be Iieves, will increase the popular ity of cross-country ski ing by mak i ng the sport less chai I eng ing for beginners. The brakes, currently being tested by a

To make this happen, an electr ic current from the bottom of the skis pulses through the ice, melting a thin layer of snow that instantly ref

Atomic, a leading ski-maker based in Austria, plans to introduce a system later this year that runs a diagnostic safety check to ensure that the ski binding is properly closed, with the resuIt being shown on

A chip inside the racket con

This energy i s then used to generate a counter-force in the piezo-electric fibres that causes a dampening effect. Al I of this, the f i rm says, translates into less stress on

47、the eI bow. Head claims that residual vibrations in the racket are dampened twice as fast as in conventional rackets, reducing the shock exper ienced by the player1 s arm by more than 50%.No doubt purists wi I I object that this is simply not cricket. Rule-makers in many sports are now being forced

48、to consider the imp I i cat i ons of equ i pment that promises to augment athletes1 performance with el ectron i c muse I e. The International Tennis Federation, that body is responsible for setting the rules of the game, has specified in its most recent guide Iines that no energy source that in any way changes or affects the playing character istics of a racket may be built into or attached to a racket.Yet despite such wording, the guide Iine does not actually eliminate the use of Head1 s smart rackets, because there is no external energy sourcethe damp i ng effect re Iies solely on energy
