Abstract: The golf swing training device includes a position sensing unit, a tee mounted on a tee platform and a visual and audio response unit. A taut, movable cord is attached to the hip of the golfer and to the position sensing unit. The position sensing unit generates forward, rearward and fore-strike position signals based upon a forward optimal position, a rearward optimal position and an excessive forward position of the hip of the golfer. This excessive forward hip position is preferable immediately prior to striking the ball and corresponds to the fore-strike position signal. The visual and audio response unit, located adjacent the tee platform, visually indicates to the golfer when his or her hips exceed the forward optimal position, and the rearward optimal position. These are negative feedback signals.

Abstract: The present invention provides for projecting supported objects, such as baseballs, footballs or golf balls. The apparatus includes a movable striker having a first surface (a target surface) for receiving a force, and a second surface (a projecting surface) for projecting the object, with the object being supported by a supporting surface. The supporting surface may be a portion of the second (projecting) surface or another surface on the striker, or alternatively may be a portion of a support member separate from the striker. The target surface receives a force from the user, the force being subsequently transmitted through the striker to the supported object via the projecting surface. The striker may be movably coupled to a base, with the striker being limited to fore-and-aft movement relative to the base, so that the object will be projected forwardly in a predetermined direction even if the target surface is not struck in a squarely forward direction.
