1. An external device for a hearing implant system comprising:

  • an external transmitter for generating a radio-frequency inductive link signal to an implanted receiver, the inductive link signal including;

    i. a sequence of data word segments which communicate data to the implanted receiver, and ii. a sequence of data word pause segments between each data word segment which communicate energy without data to the implanted receiver; and

    a data word pause controller for controlling the inductive link signal during the data word pause segments according to an energy management rule reflecting current energy needs of the implanted receiver;

    wherein the energy management rule includes maintaining a supply voltage within the implanted receiver above a minimum supply voltage level.
