Patent ID: 8035335

Claim:
A method for providing supplemental power to a Radio Frequency Identification (RFID) interrogator in a headset in an RFID system, comprising: mounting a microphone boom of the headset to a piezoelectric transducer, wherein a vibration of the boom deflects the piezoelectric transducer to generates a current due to the deflection; integrating an RFID tag within the microphone boom of the headset, the RFID tag including a charge pump for harvesting energy from an antenna of the RFID tag, the energy obtained from any RFID interrogators in the RFID system; charging an energy storage device disposed within a body of the headset with the generated energy from the RFID tag and the current from the piezoelectric transducer; conditioning power from the energy storage device with a buck boost regulator disposed within a body of the headset; and powering the RFID interrogator of the headset with the conditioned power from the energy stored in the energy storage device.
