Wireless communication over a transducer device
First Claim
1. A method for supporting inductive communication, the method comprising the steps of:
- coupling a transducer to a selected first or second circuit for either transmitting or receiving;
adjusting electrical characteristics of the first circuit to increase a magnetic field generated by the transducer;
adjusting electrical characteristics of the second circuit to increase a signal generated by the transducer.

Abstract
One aspect of the present invention is generally directed towards a system and method of tuning a transducer for transmitting and receiving a wireless signal. In an illustrative embodiment, a single transducer is coupled to a first or second circuit for either transmitting or receiving, respectively. Generally, electrical characteristics of the first circuit are adjusted to increase a magnetic field generated by the transducer. Conversely, electrical characteristics of the second circuit are adjusted to increase a signal generated by the transducer for receiving a magnetic field. Accordingly, a single transducer device can be tuned for either transmitting or receiving a corresponding wireless signal.

11. A method for supporting communication, the method comprising the steps of:
-
switching to select either transmitting or receiving over a transducer;
via a first circuit, effectively tuning the transducer to be a low impedance device for generating a magnetic field when a transmitter is switched to transmit over the transducer;
via a second circuit, effectively tuning the transducer to be a high impedance device for receiving a magnetic field when a receiver is switched to receive over the transducer. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
