A golf club head is formed by integrally welding a face portion and a back portion with each other. The face portion has a circumferential edge portion in its back surface. The circumferential edge portion is made of a flat surface all over its circumference. In the rear surface of the face portion, the part other than the circumferential edge portion is formed as a recess portion. In the bottom surface of the recess portion, a first bottom surface which is the deepest, a second bottom surface which is the second deepest, a third bottom surface which is the third deepest, and a fourth bottom surface which is the shallowest are formed in descending order. Three ribs are provided vertically to extend through the recess portion.

A faceplate for golf clubs, such as a putter, iron or driver designed to control the spin of a golf ball after impact. The volume immediately behind the striking face comprises a plurality of angled elements which may be holes, slots or objects such as pixels, bars, or pins. Compression and rebound of the faceplate upon impact imparts spin to a golf ball according to the choice and arrangement of the angled elements. The invention can be used to start a ball rolling at impact with a putter head, thus enhancing the accuracy of a putts. The invention may also apply corrective spin to off-center putter hits, increase backspin for greater loft and chipping control, or correct for hooking and slicing side-spin in off-center hits with iron or drivers.

A golf club head is disclosed that comprises a body having a striking face, a rear cavity and a sole bar, wherein a recess is formed in the sole bar that extends generally from the rear cavity.

The intermediate layer has a hardness and a modulus of elasticity that are less than that of the core, such that when the golf club head is used to strike a golf ball, the resulting vibrations are dissipated by compression of the intermediate layer and movement of the core with respect to the intermediate layer.

The present invention provides a method and apparatus for accurately positioning a robotic pool-playing device. The system comprises a computer controlled robotic positioning device, such as a gantry robot, that can position a cue over the pool table and place a shot. A global camera is mounted on the ceiling looking down at the table, and the acquired images are transmitted to the computer for analysis to determine the identity and locations of the balls within the table coordinate reference frame. The computer also automatically determines which ball to strike. An aspect of the invention is the use of a local camera, mounted on or near the robotic end-effector in a fixed relationship with the cue, to improve the positioning error of the robotic device prior to placing a shot. By comparing the ball locations perceived from the vantage of the local camera with the known ball locations determined from the global camera image, the invention can calculate the acquired robotic positioning error, which can then be corrected for prior to placing the shot.

A golf club head is composed of elastic substructures having moderate elasticity and consisting of a face, outer shell, and inner structure in which said elastic substructures that cooperate so as to provide larger impulses to the ball at impact, due to combined elastic properties of the club face for hits at all locations on the face. This allows better distance of shots when loft angle and other design details are appropriately chosen. The structure also minimizes variations of angular orientation of the face surface at the point of impact for all such hits. The elastic substructures can take several forms such as an internal elastic support around the periphery of the face structure, an internal support for the central part of the face structure, and an elastic structure attached to the front side of the face structure, an elastic outer shell, and their combinations. The structure also provides adequate strength, and minimum weight such that a maximum amount of concentrated mass can be located in advantageous places as far as practical from the center of gravity of the head so as to realize maximum moments of inertia about the center of gravity.
