1. A system for stimulating a sensory organ, the system comprising:
- an external portion for receiving sensory stimuli in real time and wirelessly transmitting the sensory stimuli in real time as a 16-ary FSK signal having a plurality of frequencies, the external portion including a stored waveform, and wherein the external portion generates the 16-ary FSK signal by sampling the stored waveform at sampling rates indicative of the frequencies; and
an internal portion in data communication with the external portion, the internal portion for receiving the 16-ary FSK signal in real time and for causing stimulation of the sensory organ in response to the 16-ary FSK signal.

Abstract
An apparatus for stimulating a sensory organ includes an external portion and an internal portion. The external portion is configured for wireless transmission of an FSK signal having encoded therein information indicative of sensory stimuli. The internal portion, which is in data communication with the external portion, is configured for wireless reception of the FSK signal and for causing stimulation of the sensory organ in response to the information encoded in the FSK signal.

8. A method for stimulating a sensory organ, the method comprising:
-
receiving a series of symbols indicative of an ambient stimuli; decoding the symbols to produce selection signals; sampling a stored waveform, wherein the frequency at which the stored waveform is sampled depends on the selection signals; converting the sampled waveform to an analog waveform; generating an FSK signal having a plurality of frequencies from the analog waveform, wherein each frequency in the FSK signal is indicative of a particular symbol in the series; wirelessly transmitting the FSK signal transcutaneously to an implanted receiver; and stimulating the sensory organ in response to the information encoded in the FSK signal. - View Dependent Claims (9, 11, 12, 13)

14. A cochlear implant system comprising:
-
an externally-worn portion for receiving audio stimuli in real time and wireless transmitting the audio stimuli in real time as an FSK signal having a plurality of frequencies, the externally-worn portion including a stored waveform, and wherein the FSK signal is generated by sampling the stored waveform at sampling rates indicative of the frequencies; an implantable portion having a receiver for wireless reception of the FSK signal in real time; a processor for generating stimulus signals on the basis of the received FSK signal; and an electrode array responsive to the stimulus signals. - View Dependent Claims (15, 17, 18)
