Abstract: A portable game machine electronically executes target games and has an input unit, a game processing unit, and a display unit in a housing. A plurality of targets to be hit are displayed on the display unit. First kicking data concerning an X coordinate when a ball reaches one of the targets and second kicking data concerning a Y coordinate when the ball reaches one of the targets are successively input by the game player through one of the operation keys provided for the input unit. By using the information of the first kicking data and the second kicking data, the game processing unit determines whether the ball hits one of the targets defined by the X coordinate and the Y coordinate. Based on the determination result, an image of the target after the ball has been kicked is displayed on the display unit.

Abstract: A golf-swing training device includes a neck strap for wearing about the neck of a golfer-under-training. A tether strap connects to a front part of the neck strap and has an adjustable length. A foot plate is connected to a distal end of the tether strap, and is intended to be held under a foot of the golfer-under-training. Such provides for the head and neck of the golfer-under-training to be held at a constant elevation during a swinging of a golf club. A clip may be attached to the middle of the tether strap and the clothing of the golfer-under-training so the tether strap will be kept close in and away from the swinging golf club.

Abstract: 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.

Abstract: A portable return net device for receiving, arresting and returning a ball to a central collection point for pitched, thrown or batted balls in a ball practice system. The return net apparatus comprises; a net supporting frame, a net for receiving a projected ball, an inclined collection tray operatively associated with the net, and an exit chute, wherein the net is hung untensioned on the supporting frame, on the diagonal, and wherein flaps extending transversely across the base of the hanging net are pivotally connected thereto. The net absorbs the impact of a ball in conjunction with the flaps which trap a ball impacting a tensile zone of the net. The tensile zone comprises that portion of the hanging net below which there is insufficient net weight to arrest a ball in a triangular portion of the net below the point of impact. The arrested ball is conveyed by the collection tray to the exit chute for reuse.

Abstract: The present invention is directed to improved regulation multi-layer golf balls. A smaller and lighter core is produced and metal particles, or other heavy weight filler materials, are included in the cover compositions. The resulting molded golf ball exhibits enhanced interior perimeter weighting. Preferably, the particles are included in a relatively thick inner cover layer (or mantle) of a solid, three-piece multi-layered golf ball. The size and weight of the core is reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. The combination of the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin. This results in a golf ball exhibiting enhanced distance without substantially effecting the feel and durability characteristics of the ball.

Abstract: An improved means for dispensing powder and shaping/scuffing the tip of a billiard cue, for use during a game of billiards, is herein disclosed. The design of the compact, substantially cylindrical device incorporates the combination of portability, functionality, user discretion, and neatness/convenience of use lacking in the prior art. The device provides a simple, yet reliable means of dispensing small, easily controlled amounts of powder onto the hands of billiard players via the use of a ball and spring assembly. The device allows the user to dispense/apply the powder by (1) compressing the assembly and “rolling” the powder, or (2) “tapping” the ball and spring assembly on the appropriate area of the hand(s). The present invention is a device that also includes a shaping/scuffing tool, on the end opposite the ball and spring assembly, that allows an individual to manicure the tip of a billiard cue.

Abstract: In an athletic ball server, a collapsible tripod supports an elongated inclined tray containing a linear array of balls. A gate at the low end of the tray cyclically releases balls one at a time from the array to gravity. One edge of a trampoline is pivoted on the tripod. The central portion of the trampoline is aligned to bounce a ball released from the tray. An eye-bolt is connected between the tripod and the trampoline allowing the angular position of the trampoline to be varied. By adjusting the eye-bolt, it is possible to achieve any desired trajectory of the bounced ball from a pop-up or slow pitch trajectory to a ground ball trajectory.

Abstract: An apparatus to measure leg drive of a pitcher as the pitcher as delivering a pitch is presented. The device comprises a pressure gauge integrated into a pitching rubber to provide a pressure profile of the leg drive utilized by the pitcher during delivery of a pitch. This device would be useful in evaluating pitchers, in determining if a pitcher has recovered from injury, to determine if a pitcher is tiring during a game, and to provide a general indication of the pitchers ability to throw hard. The device could also be used a training device, and used to coach pitchers into developing a strong leg drive. The device may further be used in conjunction with additional sensors to determine the turnover ratio of a pitcher, the time from when the front foot hits the front of the mound to when the back foot comes off the pitching rubber.
