Abstract
Abstract A system for controlling the movement of at least one limb of a person's body includes an interface unit in communication with the person's body for receiving an input signal. A polynomial processor generates a control signal as a polynomial function of the at least one input signal. A generator generates a functional electrical stimulation signal. A plurality of electrodes stimulates the movement of the at least one limb by introducing the functional electrical stimulation signal to the at least one of a plurality of inactive muscles.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
97 words
A limb stimulation system comprising: an interface unit in communication with at least one limb of a person's body; a first parallel processor responsive to the interface unit; a second parallel processor responsive to the interface unit; a first generator responsive to the first parallel processor; a second generator responsive to the second parallel processor; at least one electrode responsive to the first generator, the at least one electrode in communication with at least one muscle of the person's body; a drive unit responsive to the second generator; and a bracing apparatus responsive to the drive unit.
