System for control of a prosthetic device
First Claim
1. A control system for a prosthetic device comprising:
- at least one sensor module adapted to receive at least one body input signal;
at least one device module having at least one prosthetic control mode, the device module being in communication with the at least one sensor module; and
a plurality of actuators of the prosthetic device configured to receive commands from the device module;
wherein the device module receives at least one body input signal from the at least one sensor module and commands at least one actuator of the plurality of actuators in accordance with the at least one body input signal;
wherein the at least one prosthetic control mode includes a bulk mode in which the at least one body input signal is indicative of a desired directional movement of an endpoint of the prosthetic device;
wherein the device module controls movement of the endpoint of the prosthetic device within a movement envelope having a boundary defining a limit to positions of the end point in each direction based on a length of the prosthetic device in combination with movement limitations of the plurality of actuators, the device module commanding movement of the end point within the movement envelope through each of simultaneous and separate actuations of the plurality of actuators based on the at least one body input signal in accordance with a movement function to achieve the desired directional movement of the endpoint within the movement envelope; and
wherein the device module commands a movement of the endpoint along the boundary of the movement envelope through actuation of the plurality of actuators that is different than the desired directional movement when the desired directional movement of the at least one body input signal would require movement outside of the movement envelope, the commanded movement along the boundary including at least a first directional component of the desired directional movement commanded by the at least one body input signal and at least a second directional component different from the desired directional movement commanded by the at least one body input signal.

Abstract
A system for control of a prosthetic device includes at least one Inertial Measurement Unit detecting orientation of a user'"'"'s foot. The at least one Inertial Measurement Unit is in communication with a device module configured to command at least one actuator of a prosthetic device. The at least one Inertial Measurement unit sends output signals related to orientation of the user'"'"'s foot to the device module and the device module controls the at least one actuator of the prosthetic device based on the signals from the at least one Inertial Measurement Unit. The device module controls movement of an endpoint of the device within a movement envelope. The device module commanding movement of the end point within the movement envelope through at least simultaneous and/or independent actuation of the plurality of actuators based on the at least one body input signal in accordance with a movement function to achieve the desired directional movement of the endpoint within the movement envelope.
