摘要:
To measure the rotation frequency of a moving toy, an existing radio signal in the form of a broadcast radio signal or mobile radio signal in an open system or a radio signal from an evaluation unit in a closed system is used to obtain (120), using an antenna having a directional characteristic, a time-variant radio antenna received signal which has a low-frequency modulation component whose frequency (122) corresponds to the rotation frequency of the moving toy.
摘要:
For measuring the force of a shot to which a movable gaming machine is subjected, a temporal profile of the acceleration during the shot, or of the pressure in the gaming machine during the shot, is recorded and processed in order to obtain an energy mass, this energy mass then serving to provide information about the force of the shot.
