SENSOR AND CABLE WITH LOCAL WIRELESS READ AND WRITE CAPABILITY AND METHODS OF USING SAME

摘要

Methods and apparatus for verifying a transducer are provided. In preferred embodiments, the flow of current on a wire that provides power to both a micro-processor and a transducer is reversed. A wireless communication chip listens for and receives a read request and communicates the read request to a microprocessor. The microprocessor reads the transducer data from non-volatile memory and transmits it with the wireless chip. Preferably, a hand held device is used to initiate the transfer of and receive the transducer data.
