Abstract
Abstract To provide controlled amounts of resistance to movement in exercise equipment or in orthotic devices, a control module has cooperating resistance elements. The force between the elements is varied in accordance with the position of the elements with respect to each other. For example the control module can connect two splints of a knee brace so that the resistance to flexion and extension are programmed in accordance with the position of the leg and thigh with respect to each other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
An exercise device comprising: a first member adapted to be connected to one limb about a joint; a second member adapted to be connected to another limb connected to the same joint as the one limb wherein the first and second members articulate about the joint; a module connecting the first and second members and controlling the force necessary to articulate the first and second members; said module including a braking means, a feedback means and friction means for resisting movement of the first and second members with a frictional force independent of speed of movement which frictional force is varied by said braking means; said feedback means including means for energizing and de-energizing the braking means at the different angles between the first and second members, wherein the braking means is controlled by the position of the first and second limbs to provide for a first series of first periods of time having a first frictional force and a series of second periods of time having a second frictional force during which second periods of time each of the limbs can be moved; the first periods of time being separated from each other by said second periods of time.
Claim 2
Dependent Claim
200 words
An exercise device comprising: a first member adapted to be connected to one limb about a joint; a second member adapted to be connected to another limb connected to the same joint as the one limb wherein the first and second members articulate about the joint; a module connecting the first and second members and controlling the force necessary to articulate the first and second members; said module including a braking means, a feedback means and friction means for resisting movement of the first and second members with a frictional force independent of speed of movement which frictional force is varied by said braking means; said feedback means including means for energizing and de-energizing the braking means at the different angles between the first and second members, wherein the braking means is controlled by the position of the first and second limbs to provide for a first series of first periods of time having a first frictional force and a series of second periods of time having a second frictional force during which second periods of time each of the limbs can be moved; the first periods of time being separated from each other by said second periods of time.
Claim 3
Dependent Claim
68 words
An exercise device in accordance with claim 1 further including a timing means whereby the times the braking means is energized and de-energized is controlled so that it is energized to provide a braking operation at a predetermined series of angles corresponding to different amounts of flexion and means for controlling a time duration during which the braking means is energized under the control of the timing means.
Claim 4
Dependent Claim
93 words
A device according to claim 1 further including: connecting means between the module and at least one of said first and second members, whereby the resistance to movement of the first and second members with respect to each other about said module is angular movement; said connecting means including means for permitting movement between said module and said one of said first and second members in a linear direction, whereby an eccentric movement of said first and second members with respect to each other about a joint of the person may be accommodated.
Claim 5
Dependent Claim
57 words
A device according to claim 1 further including means for reducing ortho-kinetic joint movement discord; said means for reducing ortho-kinetic joint disorder being connected to said first and second members adjacent to said module and including means for varying the resistance to movement of the first and second members with respect to each other about said module.
