ABSTRACT:
An abnormal tire condition warning system is disclosed for use in pneumatic tires. The self-contained device comprises a sensor, an electronic transmitter and a power supply. The power supply is a weighted, vibrating arm that has a piezoelectric transducer attached. Normal wheel vibrations cause the weighted arm to vibrate and flex, in turn causing the transducer to flex, thus producing electrical energy.
