1. An aural prosthesis system comprising:
- a first part adapted to be located exteriorally of the body to transmit a data signal and a second part adapted to be located within the body to receive said data signal,said data signal comprising a plurality of sequential frames of an audio signal,each of said frames having a set of channel signals,each member of said set of channel signals including a first portion indicative of the channel signal intensity and a second portion indicative of the channel signal timing within the associated frame,a transmitter in said first part for transmitting said frames of said data signal as a series of sets of channel signals,a receiver in said second part for receiving the signal transmitted by said transmitter,first storage means in said second part for storing each member of a set of channel signals as it is received,loading means to load said sets of channel signals into said first storage means,second storage means in said second part to store each member of a set of channel signals,a plurality of electrodes adapted to be coupled to stimulate aural nerve endings, andcoupling means to couple each member of the set of channel signals in said second storage means to a separate one of said electrodes, said first portion of each said members of said set determining the intensity of stimulation to be applied by the associated electrode and said second portion of each of said members of said set determining the time within the associated frame in which that stimulation is initiated by said associated electrode,said coupling means coupling the channel signals of a frame from said second storage means to said electrodes while said loading means is loading the set of channel signals from the next successive frame into said first storage means.

Abstract
A prosthesis and specifically an aural prosthesis which includes an implantable component which is in connection with means which can selectively stimulate neural endings the component being arranged to receive a signal from an extension component which converts a parameter into a transmittable form and which includes a transmitter, the signal from the transmitter received by the implanted component which resolves the signal into groups of two components which can selectively stimulate the neural endings, the stimulation to each ending being independent to stimulation of each other neural ending in both intensity and phase.
