Energy source recharging device and method

摘要

The invention relates to a wireless communication device that is coupled to a rechargeable energy source, such as a battery or capacitor. The wireless communication device is adapted to receive an energy-bearing signal and recharge the energy source coupled to the wireless communication device. The wireless communication device can use energy from the energy source when not in the field of an interrogation reader, transmitter, or other energy source for communication. If the energy source is above a threshold energy level, the wireless communication device will use the energy-bearing signal to recharge the energy source. The wireless communication device will discontinue recharging of the energy source if the energy source is fully charged. The wireless communication device is capable of using the energy-bearing signal for both receipt of information and recharging of the energy source.
