First Claim
1. An apparatus in a near field communication capable electronic device, the apparatus comprising:
- an antenna to receive a near field signal from a recharging pad or a reader to provide a reception signal;
a detector coupled to the antenna to receive the reception signal and detect therefrom a voltage, current or power value representing a power level of the near field signal; and
a switch coupled to the detector, to switch 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, current or power value.

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.
