When Olympic medalist Bernard Lagat set a new American record in Boston earlier this month, he was wearing a prototype wireless tracking tag from Haverhill-basedLynx System Developers Inc.

As Lagat rounded the track at the Reggie Lewis Track and Athletic Center in Roxbury, running the 5000 meters in thirteen minutes and eleven seconds, the tag relayed information about his precise position on the track to a Lynx computer system in a control room above the action, which enabled a robotic camera to closely follow Lagat, and provided detailed new information for the ESPN announcers who were calling the race.
