  • Publication number: 20150017620
    Abstract: I have invented a tool to enable a golfer to determine his/her TrueAim to the hole when putting. The premise of the invention is that no two sets of eyes see or aim in exactly the same fashion and the device allows the individual golfer to establish and practice his/her TrueAim. The device is designed for a person to practice with and to train the individual to determine the aim of a putt, and then enable the individual to properly align based on that aim determination. Unique features of the device allow the golfer to align to a point within the cup just a few inches in front of the ball, and allows the golfer to align the putter to that spot and thereby align to what the golfer believes is the TrueAim of the putt.

    Abstract: Golf teaching and club positioning methods utilize a golf club with a cavity configured to accept the footwear of a golfing instructor, partner, or other assistant. The head of the club has a flat bottom. Once placed flush on the ground, the club is positioned at the proper shaft angle with the club face aligned towards the target, and the assisting individual places his foot into the cavity of the head to maintain it in this position. The golfer then “steps into the golf shot” by accepting the pre-aligned club and positions himself with the club. When the assister's foot is removed from the cavity, the golfer is free to swing the club in the proper pre-shot position. The golf club can be used while playing a round of golf, and also in the teaching process.

    Abstract: A call center system for coaching a player in judgmental aspects of an athletic sport or for practicing judgmental aspects of the sport includes a call center computer having a display and a memory. The system may also include a camera, a telephone, and a position locator system. Either the pictures stored in the memory or pictures taken with the camera are used to provide coaching or practice. Pictures of a golf course, golf course mapping data, or both are stored in a call center system. GPS data indicating the position of a golf ball on a golf course hole is used to provide either an overhead view of the hole and terrain features, pictures of the course at or near the location of the ball, or both, on a golf professional computer display.

  • Patent number: 8376751
    Abstract: An apparatus and method for detecting and correcting improper head neck and back movement during sports. The apparatus may include a non-reflective shield positioned near at least one eye of a user. The shield may be oriented at an angle parallel to a users' vision while in the open position, and the shield may be oriented at an angel perpendicular to a users' vision while in the closed position. Additionally, a swing arm or movement response unit may move the position of the shield from open to closed in response to the movement of a user.

  • Patent number: 8314840
    Abstract: The invention relates to a method and a system for analyzing, teaching and identifying the biomechanics of body motion from a video source. Repeatable body motion activities are analyzed as a series of positions of interest that trigger superimposed smart model animations. The properties of body part images, including location, scale and rotation are determined by a combination of manual and automatic means thereby tailoring the smart models to the underlying video images of the body in motion. Based on the proximity of the subject's actual motion to the ideal-or-expected motion defined for the smart models, quantitative characterizations of the motion performance are made.

  • Patent number: 8257087
    Abstract: Methods and equipment to improve the visual ability of a subject during athletic activities are provided. One such method includes configuring a sporting object to visually approximate the appearance of a background or configuring a background to visually approximate the appearance of a sporting object. A subject may then train using the sporting object visually in front of the low contrast background. A background where the visual appearance of the background comprises at least one depiction of the sporting object may be used. A subject may then train using the sporting object visually in front of the background.

  • Patent number: 8221257
    Abstract: The presented invention relates to a method for determining the effectiveness of a golfer's swing without the requirement of the club head making contact with a golf ball. More specifically, the present invention relates to a measurement and analysis system comprising a first module that attaches to the club head and captures measurement data and relative position data during the entire swing, further first module wirelessly communicates bi-directionally with a second module that is further connected to a user interface device and computational engine where feedback results are calculated and conveyed to the golfer. The system provides comprehensive feedback for swing characterization including detailed swing timing metrics, dynamic club head orientation and motion metrics and dynamics shaft action metrics all referenced to the spatial domain.

  • Patent number: 8192295
    Abstract: A method, system and golf ball determine the side spin and/or back spin of a golf ball to facilitate the evaluation of a putt. In one embodiment, a system includes a golf ball and an offboard display device. The golf ball includes a golf ball body, a motion sensor disposed within the golf ball body and configured to measure acceleration of the golf ball along each of three mutually perpendicular axis, and a transmitter within the golf ball body transmits data representative of spin of the golf ball. The display device includes a receiver and a display, and the receiver receives data representative of the spin of the golf ball from the transmitter and the display is configured to provide a representation of a measure of the spin of the golf ball.

  • Publication number: 20120040317
    Abstract: A method of golf instruction utilizing a schematic represented by a plurality of vertical, diagonal and circular lines which demonstrate a preferred golf swing. A video recorder, processor and monitor can be used to record the golf swing of a student aligned within the schematic. Corrections to the students swing can be made based on the deviation from the schematic. Additionally, the flight path of the ball can be determined based upon the deviation from the schematic and the adjusted flight path can be displayed.

  • Publication number: 20110276153
    Abstract: A method for teaching golf based upon comparing a commonality of personal characteristics of a student and the personal characteristics of a group of high-level golfers is contemplated herein. Data mining is used to determine clusters of golfers with common physical characteristics and commonality of swings, based upon real-time measurements. A canonical swing is developed for each desired cluster. Prospective students have their respective personal characteristics determined and used to place them in a cluster. The canonical swing of that cluster is assigned to the student. Subcomponents of performing a canonical swing are determined for instructional purposes. Biomechanical and Newtonian mechanics are used to measure the ball flight's sensitivity to each subcomponents' accurate performance and a scoring system is produced to provide a simple measure of students' state of mastering their respective canonical swings.

  • Patent number: 8033916
    Abstract: Grip pressure is monitored by a collection of battery powered components embodied in an assembly analogous to an ordinary wrist watch, that is a watch housing or casement and a stretchable band. The system, which we shall refer to as a swing monitor, is worn on the wrist and deployed in such a way that the back of the housing or casement is cinched securely to the back or underside of the wrist. A pressure plate on the back of the watch makes contact with the pulse region of the wrist. The flexing and relaxing of the muscles and tendons of the wearer is read by an electronic pressure sensing device, a piezo sensor. A tighter grip will register greater pressure and a looser grip, less pressure. The device records grip pressure associated with the swing of a golf club, tennis racquest or baseball bat, among other articles of sports equipment meant to be swung. The grip pressure determined to be optimal, that is giving the desired result, can be SAVED in the memory of the swing monitor system.
