There's tension at the U.S. Open
KNOXVILLE, Tenn. (AP) - September 6, 2012 (WPVI) -- The tension is rising at the U.S. Open -- and not just among the tennis players.
The Open is providing a showcase for an invention by an amateur tennis player.
David Glass is a Tennessee engineer who has developed a way of measuring net cord tension.
Glass says tension varies from court-to-court and tournament-to-tournament.
He says Wimbledon is "notorious" for very loose nets.
Glass has a patent on his TNT Gauge system.
It was tested at the U.S. Open last year on two courts.
It's being used on all the courts this year.
