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.
