In another embodiment, the dual-layered core has an inner core comprising a thermoplastic composition and outer core comprising a thermoset composition. The thermoplastic composition preferably comprises an ethylene acid copolymer ionomer and plasticizer. The thermoset composition preferably comprises polybutadiene rubber. The ball further includes a cover of at least one layer.

A user terminal includes a communication device configured to receive radio waves transmitted from a wireless communication tag provided on a golf ball, an output device configured to output information to a user, and a controller configured to control the output device and output information according to radio waves transmitted from the wireless communication tag provided on a golf ball.

Method of making golf ball comprising providing subassembly and forming at least one layer thereabout comprised of a thermoset polyurethane created using prepolymer prepared by: reacting stoichiometric excess of first isocyanate with at least one long chain polyol and/or polyamine soft segment to create first isocyanate-terminated first prepolymer with (% NCO).sub.FIRST PREPOLYMER; and adding stoichiometric excess of additional isocyanate to the first isocyanate-terminated first prepolymer to produce modified-first prepolymer with (% NCO).sub.MODIFIED-FIRST PREPOLYMER; wherein (% NCO).sub.MODIFIED-FIRST PREPOLYMER>(% NCO).sub.FIRST PREPOLYMER. Reacting a stoichiometric excess of isocyanate in multiple steps and staggering addition of total amount of free, reactive, and unreacted isocyanate functional groups into the isocyanate-functional final prepolymer produces an improved final prepolymer as well as a resulting thermoset polyurethane with better physical properties compared with conventional thermoset polyurethanes based on conventional prepolymers wherein the total % NCO is added in a single step or not at all until well into the prepolymer formation process.

Golf ball may additionally have third aerodynamic coefficient magnitude between about 0.27 and about 0.32 and third aerodynamic force angle between about 34 degrees and 39 degrees at Reynolds Number of 133000 and spin ratio of 0.133; and fourth aerodynamic coefficient magnitude between about 0.33 and about 0.38 and fourth aerodynamic force angle between about 38 degrees and 43 degrees at Reynolds Number of 89000 and spin ratio of 0.183.

A golf ball comprising: (a) a core; (b) an inner mantle layer; (c) an intermediate mantle layer; (d) an outer mantle layer; and (e) at least one cover layer; wherein the core has a PGA compression of less than 70, and the core/inner mantle layer/intermediate mantle layer combined construct has a PGA compression of at least 30.

A golf ball comprising: (a) a core; (b) at least one mantle layer adjacent to the core; (c) an inner cover layer adjacent to the mantle layer; and (d) an outer cover layer adjacent to the inner cover layer, wherein the inner cover layer has a material Shore D hardness that is at least 3 less than the material Shore D hardness of the outer cover layer, and the inner cover layer has a thickness of less than 0.050 in.

Racket Golf is a golf-style game intended for leisure and friendly competitive play used in common recreational areas such as backyards, parks, beaches, paved surfaces, and within large building spaces. It consists of a Racket Golf club designed to strike a plastic projectile toward a moveable target hole. The Racket Golf club may include string webbing similar in configuration to a tennis or badminton racket. The Racket Golf projectile consists of a ball and tee which in one embodiment are separate pieces and in another embodiment are attached to one another. The tee would serve to hold the striking surface of the projectile above the playing surface, and in the attached version, would also limit the projectile's flight after it had been struck. The target hole is ring-shaped that may include a raised ramp about its circumference. The target hole can be moved about during play to change the difficulty or to adjust the playing par. Alternatively, the target hole can be left in place, but approached from various starting positions to vary the playing course.

The invention relates to a mobile charging station for at least one ball game device, in particular in the form of a golf ball, comprising at least one internal energy source and at least one holding means for holding and fixing at least one ball game device having integrated electronics, wherein the at least one held ball game device can be charged or can be supplied with energy by the at least one internal energy source.

An object of the present invention is to provide a golf ball having excellent approach spin performance under a dry condition and excellent approach spin performance under a condition that there is grass between the golf ball and the club face. The present invention provides a golf ball comprising a golf ball body and a paint film formed on a surface of the golf ball body, wherein the paint film is composed of at least one layer, and an outermost paint film layer located at the outermost layer of the golf ball contains, as a base resin, a polyurethane obtained by a reaction between (A) a polyisocyanate composition and (B) a polyol composition, (B) the polyol composition contains a urethane polyol as a polyol component, and the outermost paint film layer has a dynamic friction coefficient of from 0.65 to 1.2 measured with a dynamic friction tester under specific conditions.

The GPS-locating sports ball comprises a ball, a locating circuit, and software. The locating circuit may determine one or more physical parameters of the ball. As a non-limiting example, the ball may be a golf ball, a tennis ball, a baseball, a softball, or a bowling ball. The locating circuit may communicate the one or more physical parameters to the software running on a smart device. The software may be operable to assist in locating a lost ball and in monitoring improvements in athletic performance based upon an analysis of the one or more physical parameters.
