Wireless communication system
First Claim
1. 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, anda 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.

Abstract
A wireless communication system includes a first device having a communications control circuit configured to initiate transmission of a wireless communication signal, and a second device including a communication interface circuit and a number of other circuits. The communication interface circuit may be responsive to the wireless communication signal to provide information carried by the wireless communication signal to at least one of the other circuits. Alternatively or additionally, the communication interface circuit may be responsive to the wireless communication signal to receive information specified by the wireless communication signal from at least one of the other circuits and to transmit another wireless communication signal carrying the retrieved information back to the first device. In either case, the communication interface circuit is unresponsive to control thereof by any of the number of other circuits. The communications control circuit controls all wireless communication between the first and second devices.
