Latest Patents

Haggas holds a patent for a prosthetic apparatus and artificial joint. This invention features an artificial joint with two degrees of freedom, which is operated by two rotary motors. These motors allow the joint to move in one degree of freedom when operated in respective senses of rotation and in the other degree of freedom when one of the motors is reversed. The movement is controlled by a microprocessor that balances the operation of the motors. Additionally, sensors on the joint are connected to the microprocessor in a closed-loop feedback system. The prosthetic device includes a tendon that moves a movable member, and the prosthesis consists of two parts that are movable relative to one another, along with an actuator and user control. A transducer connected to the control and actuator provides signals indicating the movement effected by the actuator. The prosthesis cover is designed with a silicone laminate and a reinforcing liner.
