Abstract: A simplified method of matching a golfer to a golf club and a golf ball by measuring the golfer's club head speed and comparing that measured value to recorded sets of data which correlates a few key variables that can accurately match the golfer with the most suitable golf club and golf ball designed to achieve optimum driving performance.

Abstract: A launch monitor system including a support structure, a first light-reflecting element disposed on this support structure, a lighting unit and an camera unit. A computer receives signals generated by light patterns received by the camera unit and computes a variety of flight characteristics for the object. The system may be moved back and forth to vary the field-of-view of the camera unit. The system also computes and displays object trajectories from the computed flight characteristics which account for the characteristics of the object and the atmospheric conditions.

Abstract: A method of making molds for the production of golf balls is disclosed. A hob is made having an imperfectly spherical arcuate surface that is composed of at least two different arcs in continuous arrangement to each other. A mold half is formed using the hob so that the imperfectly spherical hob creates an imperfectly spherical golf ball cavity within the mold half. When used to make golf balls, the imperfectly spherical cavity results in golf balls having a higher degree of sphericity than golf balls made by spherical hobs and mold half cavities.

Abstract: A method and a system for measuring the spin decay rate of a golf ball. The system includes an indoor testing area, a launching device, and a measuring device positioned at a final position along the ball's flight path. When the ball is launched by the launching device, the measuring device measures the spin rate and speed at the final position. Then, the launching device can launch the ball at the speed and spin rate of the final position and a new final speed and spin rate are measured again. The spin rate difference from launching to the final position is used to determine the spin decay rate. By using discrete spin decay rate measurements, the spin decay rate profile of a golf ball during its entire flight can be measured in the indoor area.

Abstract: In accordance with the present invention, a golf ball includes an outer surface and a plurality of dimples formed thereon. At least one of the dimples is a concentric ring dimple. Each concentric ring dimple includes a central depression, and at least one annular depression that concentrically surrounds the central depression. A land ring extends between the central depression and the annular depression. When the concentric ring dimple includes additional annular depressions, land rings extend between the adjacent annular depressions. The concentric ring dimples provide additional dimple circumference over conventional dimples that occupy the same space, thereby improving the aerodynamic performance of the golf ball.

Each of the regions has a first set of dimples formed in a large triangle and a second set of dimples formed in a small triangle inside of and adjacent to the large triangle. The diameters of the first set of dimples vary such that at least one diameter of the first set of dimples is equal to or greater than adjacent dimples nearer to the dimples on the points of the large triangle, and the dimples cover more than 80% of the outer surface with diameters of 0.11 inches or greater. The total number of dimples on the golf ball is about 300 to 500.
