Abstract

A prosthetic device control apparatus and method of controlling the same. The prosthetic device control apparatus (32) comprising an input interface (34) operable to receive input control signals and a detector (40) operable to determine if a prosthetic device (10) is operatively connected to the prosthetic device control apparatus, wherein the prosthetic device control apparatus is operable, responsive to the detector, to use the input control signals to control either a computer model (52) or movement of the operatively connected prosthetic device.

Claims

1. A method of controlling a prosthetic device, the method including:

providing the prosthetic device operable to move responsive to control signals;

providing a processor executing a program comprising a computer model of the prosthetic device, the computer model operable to simulate movement of the prosthetic device responsive to the control signals;

providing a prosthetic device control dock comprising;

an input terminal for connection to a user input device, the input terminal receiving control signals from the user input device;

a mechanical prosthetic quick disconnect socket having input and output connectors and configured to transmit control signals from the prosthetic device control dock input terminal to one of the prosthetic device and the processor executing the computer model;

receiving, by the prosthetic device control dock, control signals from the user input device;

determining, by the prosthetic device control dock, if the prosthetic device is operatively connected to the prosthetic device control dock; and

depending on the determination, transmitting the control signals received by the prosthetic device control dock to either the processor executing the computer model or to the prosthetic device.

2. The method of claim 1, wherein if the prosthetic device is not operatively connected, transmitting the control signals received by the prosthetic control dock to the processor executing the computer model to simulate the movement of the prosthesis.

3. The method of claim 1 further including, if the prosthetic device is operatively connected, controlling the movement of the prosthetic device by the prosthetic device control dock providing power to the prosthetic device and providing output control signals arising from the control signals received by the prosthetic device control dock to the prosthetic device.

4. The method of claim 3 wherein if the prosthetic device is operatively connected, powering down, by the prosthetic device control dock, circuitry operable to provide control signals to the processor operable to control the computer model.

5. The method of claim 1 wherein the prosthetic control dock generates a profile of control signal assignments to grip features to control the computer model and using the same profile to control the movement of the prosthetic device.

6. The method of claim 1 wherein the input control signals comprise myoelectric signals.

7. The method of claim 1 wherein the user input device is a set of myoelectrodes for location on the limb of the patient.

8. The method of claim 1 wherein the user input device is a force sensitive key pad.
