  • Patent number: 11583677
    Abstract: An integrated headpiece for a cochlear implant system includes a microphone for outputting an audio signal; signal processing electronics for processing the audio signal; and a transmitter for transmitting a processed audio signal received from the electronics to an implanted receiver. All of the microphone, signal processing electronics, and transmitter are disposed in a common housing of the integrated headpiece. The headpiece may also be one of a set of headpieces that can be alternatively used as needed to suit power consumption requirements or environmental conditions. Cochlear implant systems include a circuit board having electronic circuitry configured to generate one or more signals configured to direct electrical stimulation of one or more stimulation sites within a patient, an induction coil configured to transmit a telemetry signal by generating a telemetry magnetic field, and a telemetry flux guide positioned between the induction coil and the circuit board.

  • Publication number: 20220296896
    Abstract: An exemplary cochlear implant system includes a sound processor, a cochlear implant, and equalization circuitry integrated within the sound processor and/or the cochlear implant. The sound processor operates externally to a recipient and is associated with a sound processor coil. The cochlear implant includes a cochlear implant coil larger than the sound processor coil and that is configured to form a transcutaneous narrowband inductive link with the sound processor coil when the cochlear implant is implanted within the recipient. By way of the transcutaneous narrowband inductive link, the cochlear implant receives a forward telemetry signal incorporating power and forward telemetry data. The equalization circuitry facilitates recovery, by the cochlear implant, of the forward telemetry data from the forward telemetry signal by compensating for distortion introduced onto the forward telemetry signal as a result of bandwidth limitations imposed by the transcutaneous narrowband inductive link.

  • Publication number: 20220123603
    Abstract: A system includes electronic circuitry that receives a self-clocking differential signal comprising a data signal encoded with a clock signal at a dock frequency. The electronic circuitry is configured to recover, from the self-docking differential signal, the data signal and the dock signal. Then, based on the recovered dock signal, the electronic circuitry is configured to wirelessly transmit, to an implantable stimulator implanted within a recipient, a forward telemetry signal representing data recovered from the data signal. Corresponding systems, methods, devices, and application specific integrated circuits (ASICs) are also disclosed.

  • Patent number: 11251660
    Abstract: A system includes an interface assembly and electronic circuitry. The interface assembly is configured to receive 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, from the self-clocking differential signal, the data signal and the clock signal at the clock frequency, and to generate, based on the recovered clock signal at the clock frequency, a synthesized clock signal at a carrier frequency. The electronic circuitry is also configured to use the synthesized clock signal to wirelessly transmit, to an implantable stimulator implanted within a recipient, AC power based on the DC power and forward telemetry data based on the recovered data signal. Corresponding systems, methods, and devices are also disclosed.

  • Patent number: 10512553
    Abstract: An inductive wireless power transfer and communication system includes an electrostatic shield for one of the coils. The electrostatic shield is inductively coupled with the coil and is configured as an open circuit. A signal processing element or elements, especially a modulator or a demodulator, are connected across the electrical discontinuity in the electrostatic shield. Because the electrostatic shield is inductively coupled to the coil, the modulator or demodulator can operate on the signal on the coil. A variable impedance element is connected across the electrical discontinuity in the electrostatic shield. Because the electrostatic shield is inductively coupled to the coil, the variable impedance element can tune the impedance of the system.
