Abstract: Embodiments presented herein are generally directed to techniques for the transfer of isochronous stimulation data over a standardized isochronous audio or data link between components of an implantable medical device system. More specifically, as described further below, a first component is configured to generate dynamic stimulation data based on one or more received sound signals.

The first component is configured to transmit the series of wireless packets over an isochronous wireless channel to a second component of the implantable medical device system.

Abstract: The present invention is related to an implantable medical device. The medical device comprises an implantable component having a receiver unit; an external charging module having a power transmitter unit; and a data module having a data transmitter unit. The units are configured to establish a transcutaneous communication link over which data and power is transmitted on a single frequency channel via a time interleaving scheme comprising successive frames each divided into at least two time slots, and wherein one or more of the time slots in each frame is allocated to the data transmitter unit, and wherein one or more of the time slots in each frame is allocated to the power transmitter unit, and wherein data and power are transmitted by the transmitter units during their allotted time slots.

Abstract: Certain medical devices, such as auditory prostheses, have an implantable portion and an external portion. The implantable portion and external portion each include a transmission/receiver coil that communicates signals between the two portions. The implanted coil is implanted about the ear canal while the external coil is disposed about the pinna or in the ear canal itself. The proximity of the two coils allows for signal transmission between the implantable and external portions.

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.

Abstract: Presented herein are techniques for wirelessly transferring power signals (power) through the use of a quantized wave-shaped signal, referred to herein as “quantized waveform.” In particular, a quantized waveform generator comprises a pulse generator and a set of amplifiers that are grouped over a distributed resonance capacitor part of a series resonant tank circuit. These amplifiers are driven in a predefined sequence of pulses in order to generate a step function output (quantized waveform). The quantized waveform is used to drive a power transmission coil to cause the power transmission coil to emit wireless power signals at a predetermined operating frequency. The predefined sequence used to drive the amplifiers is such that one or more harmonic components of the operating frequency are substantially eliminated.
