Abstract: An orthopedic device configured to provide support and/or resistance to a joint. The orthopedic device is adjustable and lightweight and configured to permit a substantial full range of motion of the joint. The orthopedic device can comprise a torso portion, an upper arm portion, and a support system, wherein at least the support system is adapted to mimic part of the muscular system structure and function of the muscles that are used during the range of motion of the joint.

Abstract: The disclosure described herein is directed to an orthopedic device configured to provide support and/or resistance to a joint. The orthopedic device is adjustable and lightweight and configured to permit a substantial full range of motion of the joint. The orthopedic device can comprise a torso portion, an upper arm portion, and a support system, wherein at least the support system is adapted to mimic part of the muscular system structure and function of the muscles that are used during the range of motion of the joint.

Abstract: A golf putting device includes a shell which presents a ball receiving chamber open at the front to receive incoming putted golf balls. A row of LED's across the front of the compartment may be selectively energized to vary the target area from cycle to cycle. An infrared transmitter on one side of the chamber emits energy which is received by two receivers located on the opposite side of the chamber. By sensing the time one beam is intercepted by the ball and using the known ball size, the ball speed can be calculated. By sensing the interval between the times the two beams are intercepted and using the ball speed, the position of the ball transversely can be calculated to determine whether it is on target or off target. An automatic ball return mechanism includes a paddle which sweeps the ball forward in the chamber and pivots to eject the ball back to the starting position.
