Abstract: A system for performing a welding operation, such as a spot weld, using a robot incorporating an articulated and movable arm terminating in a weld gun. The system includes a portable and rechargeable electrical supply unit adapted to being secured to the robot arm in communicable fashion with the weld gun. The electrical supply unit includes a charging component, such as a battery, and a delivery (high capacitance/low voltage) component. A docking unit is positioned at a remote and accessible location relative the robot arm and associated supply unit, a primary voltage supply communicating with the docking unit. The electrical supply unit associated with the robot arm is electrically communicated with primary voltage input of the docking unit in a first charging condition.

Abstract: A golf training device to aid golfers in developing a proper swing and to overcome sway, comprising a flexible cord attached at one end to one end of a strip of material, sold under the trademark VELCRO, adapted to be attached to a similar strip of material mounted on the back of a golfer's glove; a strap for connecting the other end of the cord, in the form of a loop, to the corresponding leg of the golfer; and a clamp for adjusting the loop to provide a cord length to suit the height and arm length of the golfer, the two strips of material being of the well known hook and loop fabrics providing interlocking engagement when pressed together and producing an audible signal when separated or pulled apart upon certain arm and body movements of the golfer. When the downswing is started correctly, the VELCRO strips should separate.
