Abstract
When the charge of a battery in a mobile telephone is less than a predefined level, a recharge request message or notice is wirelessly transmitted to a charging module. In response, the charging module begins transmitting a radio frequency signal. The mobile telephone receives the radio frequency signal and extracts energy therefrom which is used to recharge the battery. When the charge of the battery is greater than a predetermined level, recharging the battery terminates and a termination message is wirelessly transmitted to the charging module, which responds by discontinuing transmission of the radio frequency signal.
