Apparatus and method for non-contact recharging and near field communication in a portable electronic device
First Claim
1. An apparatus comprising:
- near field communication circuitry to be operated using a first signal having a first characteristic;
charge circuitry to be operated using a second signal having a second characteristic;
an antenna capable of supporting near field communication and charging; and
a controller operatively coupled with the antenna, the controller configured to;
receive a signal from an electronic device external to the apparatus;
determine whether a characteristic of the signal corresponds to the first characteristic or the second characteristic; and
selectively couple the antenna with a corresponding one of the near field communication circuitry and the charging circuitry based at least in part on the characteristic of the signal.

Abstract
Apparatus and methods in a near field communication capable electronic device are disclosed. An antenna receives a near field signal from a recharging pad or a reader to provide a reception signal. A detector coupled to the antenna receives the reception signal and detects therefrom a voltage, current or power value representing a power level of the near field signal. A switch is coupled to the detector, and switches the reception signal corresponding to the recharging pad or the reader to a recharging transceiver to recharge a battery, or to a near field communication transceiver, respectively, on the basis of the detected voltage. A Hall-effect type magnetic sensor may be used as an alternative to the detector.
