Systems and methods for wirelessly transmitting power and data from an active headpiece to a cochlear implant

摘要

A headpiece included within a cochlear implant system includes a housing, an interface assembly disposed within the housing and communicatively coupled to a sound processor, and electronic circuitry disposed within the housing. The interface assembly receives, from the sound processor, direct current (DC) power and a self-clocking differential signal comprising a data signal encoded with a clock signal at a clock frequency. The electronic circuitry is configured to recover the data signal and the clock signal from the self-clocking differential signal, to generate synthesized clock signals at first and second carrier frequencies based on the recovered clock signal, to wirelessly transmit alternating current (AC) power at the first carrier frequency based on the DC power, and to wirelessly transmit a data-modulated AC signal at the second carrier frequency based on the recovered data signal. The AC power and data are transcutaneously transmitted to a cochlear implant implanted within a patient.
