摘要:
A goalpost for football games and the like has a pair of parallel uprights that may be moved toward and away from one another by a motor driven mechanism. A control system for driving the motor has an input signal. based on the sound level produced by spectators at a game and/or the number of Internet messages generated by TV spectators. The spectators produce a crowd roar or Internet messages when a kick through the uprights is to occur.
