Abstract: A trailer hitch positioning aid having a magnetic switching unit mounted upon the hitch ball and a corresponding permanent magnetic field unit secured to the socket of the hitch. The magnetic switches are mounted about the ball in a triangular pattern, while the magnetic field is in a "U" shape, so that closing of one or more of the magnetic switches indicates relative position of the hitch ball and socket. No physical connection is necessary between the trailer and the towing vehicle.

Abstract: An attachment for a shovel or similar tool relieving the worker of the back muscle and vertebral strain normally attendant with shoveling. The shovel aid features an elongate stem pivotally attached to the shovel handle, so that the material being shoveled may be loaded upon the shovel head, lifted, and carried sideways to be deposited, all without lifting forces upon the shovel by the hands, and without curvature of the back and spine. The shovel lifting aid may be used also with snow shovels, hoes and the like.
