Patent ID: 8095123

Claim:
A wireless communication system comprising: a first electronic device having a first control circuit configured to initiate transmission by the first electronic device of a wireless communication signal, and a second electronic device having a communication interface circuit electrically connected to a data interface circuit, the communication interface circuit having a second control circuit and circuitry responsive to energy present in the wireless communication signal to produce a supply voltage used to power the second control circuit, the second control circuit configured to convert at least a portion of the wireless communication signal to a command signal corresponding to one of a first command to provide first information carried by the wireless communication signal to the data interface circuit, a second command to receive second information specified by the wireless communication signal from the data interface circuit and a third command to poll the data interface circuit for third information, the second control circuit configured to be responsive to the first command to provide the first information to the data interface circuit, to the second command to receive the second information from the data interface circuit and control the communication interface circuit to wirelessly transmit the second information and to the third command to poll the data interface circuit for the third information and control the communication interface circuit to wirelessly transmit the third information only if the data interface circuit contains the third information, and wherein no circuitry on-board the second electronic device controls wireless communication between the communication interface circuit of the second electronic device and the first control circuit, and the first control circuit is instead configured to control all wireless communication between the first and second electronic devices via control of the wireless communication signal.
