Abstract: Golf is waning in popularity partly because of the difficulty of becoming a good player. A key aspect of this difficulty is in using a golf club to drive a ball in a desired direction. To make this easier, the present inventor devised, among other things, a directional golf tee structure that enables players to select a drive direction by orienting the golf tee in the desired direction and then using a golf club to strike a portion of the golf tee instead of the ball. The struck portion of the golf tee filters out or reduces the effect of golf club swing errors, thereby promoting greater accuracy. In some embodiments, the tees are configured for specific loft angles, fade, and/or draw attributes, not only providing a variety of play and training options, but ultimately making golf easier and more enjoyable for players of all skill levels.

Abstract: The “No Peek Putting” device is a golf putting training device which is designed to eliminate a golfer's urge to pick up or turn their head to peek or look at the golf ball as it begins to roll down the target line toward the golf hole. This simple designed golf putting training device is nothing more than a small rectangular shaped panel that sits 3 to 4 inches above the putting surface on four legs. This elevation allows the golf ball to roll under the putting device out of the golfer's view which eliminates the urge to peek or look at the golf ball as it rolls down the target line. It has a slot cut part way into the “Putter Side” of the device to allow the putter shaft to pass into the “No Peek Putting” training aid; this slot is called the “Stroke Groove”. The “Stroke Groove” is designed to keep the putter on the target line and gives the golfer a proper feel of a “free flowing” putting stroke because NO contact with the training device is made with the putter.

Abstract: A golf putting aid comprises first and second substantially vertically extending members and a substantially horizontally extending member attached between the first and second vertically extending members.

Abstract: This invention is an apparatus and method for measuring or analyzing a golf swing. Measurement or analysis is made relative to energy generation and transfer through a player's body and club. The measurement or analysis data is principally obtained from the player's ground-reaction forces. Processed signals are analyzed with an artificial intelligence system. Ground-reaction forces relate to reaction forces which occur between a standing surface and the player's feet. The apparatus and method measures or analyses a golf swing in an automatic manner or in an automatic and interactive manner.

Abstract: A putting training device includes a base having a top surface and an opposing bottom surface for placing on a putting surface. The top surface is a tapered surface tapering to the putting surface. A ball receiving recess can be defined on the top surface. The device also includes a ball positioning sensor positioned adjacent to the ball receiving recess and a light source for transmitting light visible from the top surface of the base. The light source is in operable communication with the ball positioning sensor to respond to a signal from the ball positioning sensor that a ball has been impacted from the ball receiving recess. When the light source receives the signal from the ball positioning sensor, the light source will transmit light for a finite predetermined period of time after the ball is impacted from the ball receiving recess.

The golf glasses of the present invention are characterized in that each of the lenses of the glasses includes a see-through section formed of a vertical gap corresponding to the pupil of golfer's eye, and the other part is a view shielding.

Abstract: Small flexible decals having a vinyl cling membrane base layer (20) attach onto the lens of conventional spectacles forming a training aid for use in sports activities such as golf. The decals cling firmly to the spectacle lens by cling attraction and do not require an adhesive. The decals occupy a small area of the lens and are positioned directly in line between the user's eyes and visual target. This creates the appearance of a projected decal image superimposed over the visual target. In golf the projected decal image appears superimposed over the golf ball and serves as a visual aid to the golfer. In one embodiment a tinted, transparent projected decal image (18) aids a golfer to establish proper alignment at address and reveals excessive head movement during the golf stroke. In another embodiment an opaque projected decal image (19) prevents the golfer from becoming visually fixated on the golf ball, thereby reducing stress and performance anxiety.

The device has a stand which includes a base for resting on the ground surface in front of the golfer, and a vertical mast. A pair of rings are suspended by the vertical mast in the path of the natural viewing angle. The rings have alignment indicia. Accordingly, the golfer observes the golf ball through the rings with both rings are concentric with the golf ball, and the alignment indicia of both rings are arranged in a straight line. Any movement of the golfer's head during the golf swing is immediately revealed to the golfer by a change in relative position between the rings and ball, and the alignment indicia deviating from a straight line.

Abstract: A feedback device, for use by a golfer to indicate head movement during a backswing. The device has a base, a forward plate having a transparent portion with a printed horizontal line thereupon, and a parallel mirrored surface located behind the forward plate. A reflected horizontal line is selectively viewed through the transparent portion. When the device is viewed at a first viewing angle, only a single line is visible, such that the reflected horizontal line is blocked from the golfer's view by the printed horizontal line. When the device is viewed at a second viewing angle, both lines are visible. Accordingly vertical head movement during the backswing is immediately apparent to the golfer when both lines become visible during the backswing.
