Abstract
Abstract The present invention is a concept to provide a means of movement control for a powered prosthetic device. An externally detectable article is implanted on a biological site where the exertion of muscle tension will impart a movement of the article. The muscle can be attached to an antagonistic natural muscle or some means of exerting an opposing tension on the natural muscle. The recipient controlled tension in the appropriate muscle moves the externally detectable article and an external detector monitors that movement and generates control signals to the means powering the device in relation to the amount and direction of movement of the implanted article.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
70 words
A transcutaneous method of exerting control on a powered prosthetic limb comprising the placement of an externally electromagnetically detectable article on a connective member between two antagonistic muscles with the relative tension on the two muscles determining the position of said article and the position of said article being externally electromagnetically detected and used to control the position of said prosthetic limb in relation to the movement of said article.
Claim 2
Dependent Claim
70 words
A transcutaneous method of exerting control on a powered prosthetic limb comprising the placement of an externally electromagnetically detectable article on a connective member between two antagonistic muscles with the relative tension on the two muscles determining the position of said article and the position of said article being externally electromagnetically detected and used to control the position of said prosthetic limb in relation to the movement of said article.
Claim 3
Dependent Claim
57 words
A transcutaneous method of exerting control on a powered prosthetic limb comprising: a. implanting an electromagnetically detectable article on a biological site capable of being moved by the action of a remaining muscle; b. externally, electromagnetically sensing the movement of said article; and c. generating control signals to the limb's power means in relation to said movement.
Claim 4
Dependent Claim
57 words
A transcutaneous method of exerting control on a powered prosthetic limb comprising: a. implanting an electromagnetically detectable article on a biological site capable of being moved by the action of a remaining muscle; b. externally, electromagnetically sensing the movement of said article; and c. generating control signals to the limb's power means in relation to said movement.
Claim 5
Dependent Claim
70 words
A transcutanceous system for controlling the motion of a powered prosthetic limb comprising: a. an externally, electromagnetically detectable article of a size and shape to be internally placed on a biological site capable of being moved by the action of a remaining muscle; and b. electromagnetic detection means externally adjacent said article disposed to generate control signals to the limb's power means in relation to the displacement of said article.
Claim 6
Dependent Claim
70 words
A transcutanceous system for controlling the motion of a powered prosthetic limb comprising: a. an externally, electromagnetically detectable article of a size and shape to be internally placed on a biological site capable of being moved by the action of a remaining muscle; and b. electromagnetic detection means externally adjacent said article disposed to generate control signals to the limb's power means in relation to the displacement of said article.
Claim 7
Dependent Claim
19 words
The system of claim 3 including a connective member adapted to be connected between a pair of antagonistic muscles.
Claim 8
Dependent Claim
28 words
The system of claim 3 where said detection means includes at least one induction coil and the movement of said detectable article alters the flux adjacent said coil.
Claim 9
Dependent Claim
17 words
The system of claim 5, including means for monitoring the change in inductive reactance of said coil.
Claim 10
Dependent Claim
14 words
The system of claim 5, including means for monitoring the change in coil resistance.
Claim 11
Dependent Claim
34 words
The system of claim 5 where said detection means includes at least two inductively coupled coils and said article changes the inductance coupling between said coils in relation to the displacement of said article.
