Abstract: An auditory prosthesis comprising an actuator for providing mechanical stimulation to a recipient. The auditory prosthesis comprises a measurement circuit for use in determining the resonance peak(s) of the actuator. In an embodiment, the measurement circuit measures the voltage drop across the actuator and/or current through the actuator during a frequency sweep of the operational frequencies of the actuator. These measured voltages and/or currents are then analyzed for discontinuities that are indicative of a resonance peak of the actuator. In another embodiment, rather than using a frequency sweep to measure voltages and/or currents across the actuator, the measurement circuit instead applies a voltage impulse to the actuator and then measure the voltage and/or current across the actuator for a period of time after application of the impulse. The measured voltages and/or currents are then analyzed to identify resonance peak(s) of the actuator.

The first component is configured to obtain static configuration data and to encode the dynamic stimulation data and the static configuration data into a series of isochronous wireless packets.

Abstract: Presented herein are implantable medical devices that comprise an implantable portion having a resonant tank circuit that is used to receive signals from one or more external devices. The resonant tank circuit is configured to operate at first and second resonant frequencies, where the first resonant frequency is optimized to exchange data with, and potentially receive operating power from, an external device, while the second resonant frequency is optimized to receive charging power. In certain embodiments, upon initiating operation of the implantable portion with at least one external device, the implantable portion is configured to force tune the resonant tank circuit to the first resonant frequency. That is, when the resonant tank circuit first begins receiving signals from an external device, the signals received at the resonant tank circuit are used to initially tune the resonant tank circuit to the first resonant frequency.
