  • timekeeping systems have been previously developed for remotely controlling a timekeeping device such as a clock.
  • the systems are particularly useful for remotely turning on and off a clock of the type typically used for athletic or sporting events.
  • none of these previous systems has been found to be fully satisfactory. In particular, these systems may be prone to external interference and may not be particularly reliable.
  • a remote controlling device including a control circuit which drives external apparatus, such as a scoreboard clock.
  • the control circuit is remotely actuated by a portable transmitter which generates an electrical signal in response to an input stimulus.
  • the input stimulus is an input pressure signal supplied by an air switch which is integrally combined with the transmitter.
  • the air switch is provided with an air tube such that blowing into the air tube activates the air switch, thereby sending a signal actuating the external apparatus such as the clock.
  • the air tube is coupled to a whistle which simultaneously actuates the air switch and emits an audible signal.

  • Schmall et. al. is also directed at an apparatus for controlling the playing time of a game. Interruptions in the playing time of the game are recorded by the transmission of acoustic signals by the referee at the beginning and end of each interruption. More particularly, a wireless receiver is connected with a time measurement device or clock which includes an actuator input for the interruption and re-starting of the time measurement. A portable transmitter is carried by the referee for providing signals to the receiver. Finally, a switch device operable by the referee is provided for the activation of the transmitter and for the transmission of the signals which interrupt and re-start the time measurement. Specifically, the whistle of the referee is connected through a thin pipe with a compressed air switch in such a way that the switch is closed on actuation of the whistle.

  • interference receiving conductors may be located outside the playing area and /or around the spectator stands and seats. Signals received from the interference receiving conductors are suppressed by comparison with the signals emitted within the playing area and received by the playing area reception conductor.
  • interference may be suppressed by providing for the transmission of two separate signals by the referee, the characteristics of which are compared with those of predetermined signals. Elapsed time is recorded only when the signal characteristics coincide with the predetermined signals.
