Abstract
A self-powered sensor detects or measures an event by converting one form of energy into another form. The converted energy may be conditioned and regulated to drive a wireless transmitter and encoder. A receiver may detect and validate a received message. If validated, the message may be processed or decrypted and processed to determine what has been identified or requested.
Claims24
A wireless sourceless sensor, comprising:
- a first transducer that generates electricity when subjected to a mechanical stress;
- and
- a second transducer that converts the output of the first transducer to a wireless communication signal;
- the first transducer and the second transducers mechanically coupled to a belt buckle to transmit the wireless communication signal when the belt buckle is engaged or released.
