摘要:
The present invention relates to a golf club head with a hitting face. The hitting face comprises a directional control portion, which has at least two zones with different flexural stiffness, such that when the hitting face strikes a golf ball the two zones deform differently to selectively control the direction of the flight of the golf ball. The directional control portion may comprise an upper zone and a lower zone, where the upper zone has a lower flexural stiffness. Alternatively, the lower zone has a lower flexural stiffness. On the other hand, the directional control portion may comprise a left zone and a right zone, and either the left or right zone may have a lower flexural stiffness to selectively control the lateral launch angle either to the left of right. The hitting face may further comprise a central zone disposed within the directional control zone, wherein the central zone has a flexural stiffness of at least about three times greater than the flexural stiffness of the directional control zone.

A launch monitor that includes substantially all of its functional components on or within a housing is disclosed. In one embodiment, the launch monitor is capable of being transported and used in any desired location. One or more camera's, flashes, and triggers may be used to acquire images of a golf club and golf ball. The launch monitor is preferably capable of receiving and transmitting data over a wireless network. Acquired images and other data may be analyzed by a processor, and then displayed using an LED, LCD or other type of display or printer. The launch monitor may “recognize” a plurality of golf clubs and golf balls based on an optical fingerprint. The optical fingerprints, which are preferably stored in a memory, allow the launch monitor to identify a golf club and/or ball substantially soon after they are placed in the field of view of the monitor Optical fingerprinting enables automatic record keeping, and storing performance data and equipment used simultaneously. This feature eliminates tedious record keeping, eliminates data entry errors, and enables rapid equipment optimization.

A method for automatically identifying an object is disclosed. Preferably, the method is used in conjunction with a performance monitor. A set of markers are selectively positioned on the surface of each of a plurality of golf clubs and golf balls. It is desired that each set of markers for a unique pattern on each of the golf clubs and golf balls. Each unique pattern is preferably acquired and stored. A player may choose any of a plurality of golf clubs and golf balls. When within the field of view of the performance monitor, the pattern on the club and ball is automatically matched with the stored patterns, thereby identifying the type of club and ball.

The present invention is directed towards a golf ball and a method of making a golf ball which comprises a center, at least one cover layer, and at least one layer of windings between the center and the cover having at least two threads. Preferably, the threads of the present invention have different physical or chemical properties and are wound onto the center of the golf ball simultaneously. The threads may be wound with varying tensions or angles. The wound layer of the present invention may be applied to golf balls with liquid or solid centers to achieve desired golf ball characteristics.
摘要:
The present invention is directed towards a golf ball and a method of making a golf ball which comprises a center, at least one cover layer, and at least one wound layer of a tensioned material windings between the center and the cover. Such golf balls have a coefficient of restitution that is optimized for low swing speed players. Since these players usually swing the club at the ball at low swing speeds, and thus get less distance from the ball off the tee, greater ball resiliency tends to provide greater distance and velocity off the tee. Preferably, the golf ball has a core having a thin wound layer of thread. The wound layer of the present invention may be applied to golf balls having liquid or solid centers to achieve desired golf ball characteristics.
