information technology today is quickly becom i nggIobaI.The Line technological deveIopments in the areas of computing,networking,and software engineering have aided the transitions frompaper to paper I ess transact i ons,and text and data med i a to mu 11 i med i a.Today,speed,efficiency,and accuracy in the(5)exchange ofi nformat i on have become pr imary too I s for i ncreas i ng product i v ity andinnovation.A ctivitie s as diverse as health care,education,andmanufacturing have come to depend on the generation,storage,andtransmission of electronicinformation.Computers are not only usedextensively to perform the industrial and economic functions ofsociety but are also used to provide many services upon which(10)humanIife depends.Med i caI treatment,ai r tra ffic control,and nat i onaIsecurity are a few examp I es.Even a smal I gl itch in the operation ofthese systems can put human Iives in danger.Computers are also usedto store conf i dent i a I data of a poIi t i caIr social,economic,orpersonal nature.This fa irly recent and progressive dependence oncomputer techno Iogy s i gnaIs a real danger for the human race.(15)Current computer systems offer new opportunities for lawbreaking andthe potent i a I to commit traditional types of crimes in nontraditionalways.For example,the threat of identity th e ft is magnified by ourre Iiance on computers to assist us in everyday act i v i t i es such asshopp i ng and pay i ng bi I Is.I dent i ty th e ft refers to al I types of cr i mein which someone wrongfully obtains and uses another(20)person1 spersonal data by way of fraud or deception,typical ly for economic gain.By making personal and credit information avaiIabIe on the Internet,peopIe open themseI ves up to the possibi I ity of a cr iminal obtainingth is information and using it for nefarious purposes.This is but oneinstance of the negative impact that overreliance on computertechno I ogy can have on society.(25)As humans cont i nue to maketechnological advances,so too do they rely more heavi ly upon thoseinnovations.This is a dangerous progression that must be temperedwith common sense and se lf-re stra in t.W e cannot allow computertechno Iogy to control too many aspects of our I ives,lest we becomevictims of our own ingenuity.Each of the fol lowing i s ment i oned in the passage as a potent i a I dangerresulting from

AI iens1,for examp I et spawned a number of mi I itaryfunded projectsto try to create sim ilar technologies.Automatic sliding doors mightnever have become popular had they not appeared on the television seriesMStar Trek”.And the popularity of fl i p-top or clamshell“mob i I e phonesmay stem from the desi re to look I ike Capta i n Ki rk flipp i ng open hiscommunicator on the same program.Now it seems that“Star Trek has done it again.This month,Americansoldiers in I raq wi 11 begin tria ls of a dev i ce insp i red by the comm badgefeatured in 1 1 St ar Trek:The Next Generat ion1.Like crew members of thestarship Enterprise,soldiers wiI I be able to talk to other members ofthei r unit just by tapping and then speaking into a smal I badge worn onthe chest.What sets the comm badge apart from a mere walkie-talkie,andappeaIs to Star Trek1 fans,is the system s apparent inte11 igence.Itworks out who you are calling from spoken commands,and connects youinstantly.The system,deveI oped by Vocera Commun i cat i ons of Cupertino,Californiat uses a combination of Wi-Fi wireless networking andVoice-overInternet Protocol(VoIP)technologies to I ink up the badgesvia a central server,akin to a switchboard.The badges are already beingused in 80 large institutions,most of them hospitaIs,to replace overheadpaging systems,says Brent Lang,Vocera5 s vice-president.Like its science-f iction counterpart,the badge is designed so thatal I functions can be carded out by pressing a single button.On pressingit,the cal ler gives a command and specifies the name of a person or groupof people,such as cal I Dr.Smith“or MIocate the nearestanesthesioIogistn.Voice-recognition software interprets the commandsand Iocates the appropr iate person or group,based on whichever Wi-Fibase-stat ion they are cIosest to.The person recei ving the caI I then hearsan audible alert stating the name of the cal ler and,if he or she wishesto take the call,responds by tapping the badge and starting to speak.That high Iights a key difference between the Star Trek comm badgeand the re a l-Iife version:Vocera*s i mpIementat i on a I Iows peopIe torej ect i ncom ing cal lst rather than hav i ng the vo i ce of the cal I er patchedthrough automatical ly.But even the most purist fans can forgive Vocerafor deviating from the script in th is way,says David Batchelor,anastrophysicist and nStar Trek”enthusiast at NASA s Goddard Space Fl ightCenter in Greenbelt,Maryland.For there are,he notes,some curiousaspects to the behavior of the comm badges in“Star Trek.When thecaptain of the Enterprise says Picard to sick-bay:MedicaI emergencyon the bridge”,for examp I ey his badge somehow connects him to thesick-bay before he has stated the destination of the call.Al lowing badge users to reject i ncom i ng calls if they are busy,ratherthan being connected instantly,was a feature added at the request ofcustomers,says Mr.Lang.But in a I most al I other respects the badgeswork just I ike thei r f ic t ionaI counterparts.This is not very surpr ising,says Lawrence Krauss,an astrophysicist at Case Western ReserveUniversity in Cleveland,Ohio,and the author of The Physics of StarTrek”.In science fictio n,A.science fiction.B.personalized ring tones.C.”Star Trek fans.D.Vocera badges.16.(B)Set 2/B B Gadgets with a Sporting Chance/BConsumer electronics:New sports equipment,from tennis rackets torunn i ng shoes,uses process i ng power to enhance performance.I s that fa i rWhy should aspiring athletes stand on the si de Iines when a spot ofelectronic assistance can put them in the middle of the game That isthe question many sports-equipment makers are asking as they sense anopportunity to boost thei r sales with high-tech products.You could cal Iit the revenge of the nerds:a new wave of microchip-equipped sportinggoods promises to enhance the performance of novices and non-sportingtypes alike-and could even make difficult sports easier.Take cross-country ski ing.Victor Petrenko,an engineer at DartmouthCollege s Ice Research Lab in New Hampshi re,has i nvented some smartski-brakes that,he be Iieves,wiI I increase the popularity ofcross-country ski ing by mak i ng the sport less chai I eng ing for beginners.The brakes,currently being tested by a ski manufacturer in the Alps,offer the necessary fr iction for a bigger kick-off force and make theskis I ess I i ke I y to s I i de backwards i n the i r trucks.To make th i s happen,an electric current from the bottom of the skis pulses through the ice,melting a thin layer of snow that instantly refreezes and acts as a sortof glue.This is not the only form of smart ski to hit the slopes.Atomic,aIead i ng ski-maker based in Austria,plans to introduce a system laterthis year that runs a diagnostic safety check to ensure that the skibinding is proper ly closedr with the resuIt being shown on a tiny bui It-inIiquid-crystal display.MeanwhiIe,tennis equipment manufacturers arehop i ng that i nnovat i on w i I I bring new zip to the i r bus i ness as we I I.Theycertainly need to do something:according to Sport Scan Info,amarket-research f i rm based in Flor ida,sa I es of tenn i s rackets in AmericafelI 12.5%during the fi rst half of 2004 compared with the first halfof 2003.With the ba I I clearly in their court,researchers at Headr a makerof sporting equipment,have devised a product that should appeal toplayers suffering from tennis eI bow.A chip inside the racket controlspiezo-electric fibres,which convert mechanical energy from the balls i mpact into electrical potent i a I energy.This energy is then used togenerate a counter-force in the piezo-electric fibres that causes adampening effect.Al I of this,the firm says,translates into less stresson the eI bow.Head claims that residual vibrations in the racket aredampened twice as fast as in conventionaI rackets,reducing the shockexperienced by the player5 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 to consider theimp I i cat i ons of equ i pment that promises to augment athletes5 performancewith el ectron i c muse I e.The International Tennis Federation,that bodyis responsible for setting the rules of the game,has specified in itsmost recent guide I ines that 1 1 no energy source that in any way changesor affects the playing characteristics of a racket may be built into orattached to a racket11.Yet despite such wording,the guide Iine does not actuaIly eliminatethe use of Head,s smart rackets,because there is no external energysource-the damp i ng effect re Iies solely on energy from the bal T simpact.Though high-tech equipment may cause controversy on the court,tennis clubs have to adhere to the gu i de I ines set for the sport,explainsStuart Miller,the IIF5 s technical manager.And if the rules allowself-generated forces to modify a racket s response,so be it.Different sports have encountered different technologies,though thefuture wi I I undoubtedly br ing more over lap.In golf,gadgets that pinpointthe location of the green using the Global Positioning System(GPS),Therule-making body o
