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.

Abstract
An external device for a hearing implant system and a hearing implant system having an external device is described. An external transmitter generates a radio-frequency inductive link signal to an implanted receiver including a sequence of data word segments which communicate data to the implanted receiver, and a sequence of data word pause segments between each data word segment which communicate energy without data to the implanted receiver. A data word pause controller controls the inductive link signal during the data word pause segments according to an energy management rule.
