    • An identification transmission system for use in an amusement device includes a transmitting antenna, a transmitter and a piezo-electric power source. The transmitter circuit is configured to broadcast a predetermined tone on a predetermined carrier frequency through the antenna. The piezo-electric power source is electrically coupled to the transmitter circuit and is configured to at least briefly provide power to the transmitter circuit. The piezo-electro power source includes a piezo-electric element, a striker, a storage capacitor and a voltage controlled switch. The striker is configured to move so as to at least briefly strike the piezo-electric element. The storage capacitor is configured to receive and store electrical charge from the piezo-electric element. The voltage controlled switch is configured to allow the storage capacitor to discharge through the transmitter circuit thereby providing power thereto after a predetermined amount of charge has been stored.
    • 用于娱乐装置的识别传输系统包括发射天线,发射机和压电电源。 发射机电路被配置为通过天线在预定载波频率上广播预定音调。 压电电源电耦合到发射机电路并且被配置为至少短暂地向发射机电路提供电力。 压电电源包括压电元件,撞击器,存储电容器和电压控制开关。 冲击器构造成移动,以便至少短暂地撞击压电元件。 存储电容器被配置为从压电元件接收和存储电荷。 电压控制开关被配置为允许存储电容器通过发送器电路放电,从而在已经存储了预定量的电荷之后向其供电。
