  • Patent number: 8690698
    Abstract: An object of the present invention is to provide a golf club classification method capable of classifying a golf swing precisely. Specifically, the present invention provides a classification method comprising steps of: partitioning the golf swing of the golfer into golf swing trajectories of a back swing, a down swing, and a follow through so as to determine a stable point in the golf swing trajectories as an origin for any two of the trajectories and to assign a two dimensional coordinate to the two golf swing trajectories; determining straight lines connecting each of one point selected within each of the two golf swing trajectories and the origin; calculating angles between each of the determined straight lines and the horizontal line respectively for the two golf swing trajectories; and classifying the golf swing based on a difference between the calculated angles.

  • Patent number: 8506425
    Abstract: A method is disclosed for matching a test golfer with a particular golf club selected from a group of golf clubs having a plurality of styles. The method utilizes data set derived in an initial procedure in which the club style preferences for each of a large number of pre-test golfers is recorded and correlated with a set of performance parameters for the golf swings of such pre-test golfers. This data enables the pre-test golfers to be classified into subgroups, in which golfers within the same subgroup generally prefer the same club style and golfers in different subgroups generally prefer different club styles. After this data set has been established, the test golfer takes a golf swing with a golf club, while performance parameters for the swing are measured. Based on the measured performance parameters and the previously established data set, the test golfer is classified according to swing type, and the optimum golf club is then selected from the plurality of styles of golf clubs.

  • Patent number: 8142300
    Abstract: According to the present invention, a torque applied from a golf player to a golf club during a swing is analyzed in a time-series manner. A DLT method is suitable as a determination procedure. Preferably, a link model is used in this analysis. Preferably, the three-dimensional coordinate of the mark provided at a position that corresponds to the link model is determined by a DLT method. Preferable analysis method includes: modeling using a golf club, and at least a part of a golf player who grips a grip member of the golf club to provide a link model in which the golf club is connected with the golf player via a joint; and analyzing the torque that acts on the joint is analyzed during the swing in a time-series manner. This joint is positioned in the vicinity of the grip member. This analysis can be applied to a method of diagnosing a swing, a method of selecting a golf club, and a method of designing a golf club.

  • Patent number: 8142301
    Abstract: A measurement setup to determine hitting parameters of a golf club includes a group of reflectors with at least two strip-shaped reflectors with retroreflective surfaces applied to the golf club shaft. The group of reflectors is attached to the club shaft with a detachable, yet tight clamp-connection. At least three retroreflective areas are arranged in a determined geometry at the club shaft and/or at the group of reflectors. At least one first reflective light barrier sends its beam at a right angle to the ideal swing path of the club head near the tee and/or the golf ball at the group of reflectors. During the penetration of the beam the three strip-shaped retroreflective surfaces elicit temporally staggered pulse-shaped signals that the receiver of the first reflective light barrier receives and which it transmits to the data acquisition device. A calibration setup is also provided.

  • Patent number: 8142304
    Abstract: Golf club telemetry equipment sends signals to a receiver in a golf round data system. The signals uniquely identify the particular club a player has selected for a stroke and the fact that a stroke has been taken. The club identification can occur either before or during a stroke. Automatic detection of clubs and strokes simplifies round data collection for the player. Club identification before a stroke permits a forecast of the result of the stroke to be presented to the player prior to the stroke. The signals can be either acoustic or electromagnetic.

  • Publication number: 20120052971
    Abstract: Wireless golf club shot count system configured to obtain spatial data from at least one sensor that is coupled with a microcontroller wherein the apparatus fits into a golf club handle or weight port or otherwise couples to a golf club. The apparatus may send a unique identifier and spatial data over a self-contained radio and antenna wirelessly to an external system that may analyze and display the spatial data in a user-friendly manner. The unique identifier and/or radio through use of non-interfering communications mechanisms allows for multiple clubs one or more players to be within range of a wireless receiver and not interfere. Adapters that may be specific to each golf club manufacture allow for coupling the apparatus to any type of golf club.

  • Patent number: 8070620
    Abstract: A method, system and golf ball are provided to determine the deceleration of a golf ball and, in turn, the speed of a green. The system may include a golf ball and an offboard display device. The golf ball may include a golf ball body, a motion sensor disposed within the golf ball body to measure acceleration of the golf ball along each of three mutually perpendicular axes, and a transmitter disposed within the golf ball body to transmit data representative of deceleration. The display device may include a receiver to receive data representative of the deceleration of the golf ball from transmitter and a display to provide a representation of the deceleration of the golf ball. At least one of the golf ball and the display device may include a processor to determine deceleration of the golf ball based upon the acceleration measured by the motion sensor.

  • Patent number: 8070618
    Abstract: A golf putting practice device/simulator and ball return with no moving parts, and method for a golfer to practice putting a golf ball in which the device is located in close proximity to the golfer and the intended target can be of any normal putting distance allowing one to practice golf putts indoors of greater length than indoor spaces normally allow. The device accomplishes this by detecting the speed and the position of the golf ball as it approaches the device. The device is programmed and configured in such a way to accurately approximate the distance and to display the direction the golf ball would have traveled had the path of the ball not be interrupted by device. The practice device can be configured to account for a coefficient of resistance commonly know as the Stimp of the green in its calculations. The device receives and returns the ball to the user then evaluates the putt data. The results are then displayed on the digital display.
