Abstract
Abstract A method and apparatus of communicating audio signals to the deaf is described. In accordance with the method described, electrical impulses characteristic of sound waves are applied either directly to the tactile sensory nerves by means of an implant or are applied simultaneously with vibrations representative of the sound waves to the nerve endings located at the skin surface. In accordance with the apparatus, a nerve stimulator applies a voltage representative of the sound waves across a pair of implanted electrodes in contact with the tactile sensory nerve such as the radial nerve branch located in the wrist or applies vibrations representative of the sound waves by means of a transducer to the skin, e.g. the finger tips of the deaf person, and electrical impulses representative of the sound waves across a pair of spaced electrodes carried by the transducer so that the same nerve endings are stimulated with both the vibrations and the electrical impulses.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
78 words
A method of communicating information representative of sound waves to a deaf person comprising the steps of: (a) translating the sound waves into electrical impulses and mechanical vibrations having characteristics representative of the sound waves; (b) applying the electrical impulses to tactile sensory nerves of the person; and (c) applying the mechanical vibrations to the same tactile sensory nerves whereby the electrical impulses enable the nerves to respond to vibrations having the frequency components contained in normal speech.
Claim 2
Independent Claim
78 words
A method of communicating information representative of sound waves to a deaf person comprising the steps of: (a) translating the sound waves into electrical impulses and mechanical vibrations having characteristics representative of the sound waves; (b) applying the electrical impulses to tactile sensory nerves of the person; and (c) applying the mechanical vibrations to the same tactile sensory nerves whereby the electrical impulses enable the nerves to respond to vibrations having the frequency components contained in normal speech.
Claim 3
Dependent Claim
17 words
The method of claim 1 wherein the tactile sensory nerves originate in the hand of the person.
Claim 4
Dependent Claim
32 words
The method of claim 1 wherein the step of applying the electrical impulses comprises applying the electrical impulses across two spaced-apart electrodes in contact with the person's pacinian or meisner nerve corpuscles.
Claim 5
Dependent Claim
54 words
The method of claim 3 wherein the step of applying the mechanical vibrations comprises applying the mechanical vibrations directly to said pacinian or meisner nerve corpuscles whereby the electrical impulses modify the regeneration time of said corpuscles to allow the corpuscles to discriminate between the high and low frequency vibrations characteristic of normal speech.
Claim 6
Dependent Claim
31 words
The method of claim 3 wherein the applying step comprises applying the electrical impulses across two spaced-apart electrodes in contact with at least one finger of one hand of the person.
Claim 7
Dependent Claim
17 words
The method of claim 2 wherein the tactile sensory nerve is a portion of the radial nerve.
Claim 8
Independent Claim
67 words
The method of communicating information representative of air pressure sound waves to a deaf person, comprising the steps of: (a) translating the sound waves into electrical impulses: (b) amplifying the electrical impulses; (c) applying the electrical impulses to the tips of a plurality of the deaf person's fingers; (d) transforming the amplified electrical signals into mechanical vibrations; and (e) applying the vibrations to said plurality of fingers.
Claim 9
Independent Claim
67 words
The method of communicating information representative of air pressure sound waves to a deaf person, comprising the steps of: (a) translating the sound waves into electrical impulses: (b) amplifying the electrical impulses; (c) applying the electrical impulses to the tips of a plurality of the deaf person's fingers; (d) transforming the amplified electrical signals into mechanical vibrations; and (e) applying the vibrations to said plurality of fingers.
