     While football fans feel strongly angry and shocked about mistakes made by referees (裁判) because

they cannot see clearly what has happened, a small German company is quietly pleased.

     For Cairos Technologies, mistakes made by referees are the kind of advertising that money cannot buy. The company has developed a tiny chip(芯片) that fits inside a football and determines whether the ball

has crossed the goal line, by being able to discover its exact location on the field. The world football

organization, FIFA, has shown interest in the technology. It is very possible that the new technology will

be used in the 2006 World Cup in Germany.

     "We've been testing the technology at the main soccer stadium in Nuremberg for some time and more

recently in an under-17 FIFA Cup in Peru," said Gunter Rohmer, a director of the company. "The

technology has performed well, and we're pretty optimistic that it will be used at the games in Germany

next year."

      The chip only weighs 12 grams, and is placed in the center of the football. It sends 2,000 signals a

second to a receiver network of 12 antennas(天线), placed around the field. The receivers then send

information about the ball's location to a central computer, and because it works in real time, it can

immediately tell the referee whether a goal has been scored. The chip even can tell when the ball crosses

the line in mid-air. Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive. Germany sports-wear giant Adidas is also optimistic about using this kind of chip

in other ball sports.

     FIFA aims to test the technology later this year at another game in Japan before deciding whether or

not to introduce it in all 12 stadiums in Germany for next year's World Cup.
