Abstract
An artificial joint with two degrees of freedom has two rotary motors that move the joint in one degree of freedom when operated in respective senses of rotation and move the joint in the other degree of freedom when one of the motors is reversed. The movement depends on balancing the operation of the motors, which are controlled by a microprocessor. Sensors on the joint are connected to the microprocessor in a closed-loop feedback. A prosthetic device includes a tendon received in one end of a slot in a movable member, whereby movement of the tendon moves the movable member. A prosthesis has two parts moveable relative to one another, an actuator, and a user control. A transducer connected to the control and the actuator provides signals indicating movement effected by the actuator. A prosthesis cover includes a silicone laminate and a reinforcing liner.

- 29. A prosthetic device comprising a tendon having a portion which engages a movable member of the device, so that movement of the tendon in a given direction urges the said movable member correspondingly, in which the said portion engages the said movable member by being received in one end of a slot within the movable member, the slot extending from the said end in a direction opposite to the said given direction.
- 38. A prosthesis comprising at least two parts which are moveable relative to one another, an actuator connected to move one of the parts relative to the other, and a control connected to operate the actuator in dependence upon a signal issued to the control by the user, in which a movement transducer is connected to the control, and also to the actuator to provide signals to the control indicative of the amount of movement effected by the actuator, and the control operates the actuator in dependence upon the signals it receives from the transducer.
