| A golf ball 2 includes a core 4, a mid layer 6 positioned outside this core, and a cover 8 positioned outside this mid layer. When a total thickness of the mid layer 6 and the cover 8 is denoted by L (mm), a Shore C hardness at a point A away from a surface of the core 4 toward a central point of the core 4 by 5L (mm) is denoted by Ha, a Shore C hardness at a point B away from the surface of the core 4 toward the central point of the core 4 by 2.5L (mm) is denoted by Hb, and a Shore C hardness at the central point of the core 4 and Shore C hardnesses of the mid layer 6 and the cover 8 are denoted by H0, Hm, and Hc, respectively; the golf ball 2 satisfies Hc−Hb>0, Hm−H0>0, and Ha−Hm>0. | ||||||

| A golf ball contains, as a structural element therein, a molded and crosslinked material obtained from a rubber composition which includes: (a) a base rubber (b) an α,β-unsaturated carboxylic acid and/or a metal salt thereof, (c) a crosslinking initiator, and (d) a metal carboxylate in which the carboxylic acid bonded to metal is of two or more different types and at least one of the carboxylic acids has 8 or more carbon atoms. The rubber composition has an improved processability in kneading and other operations, and the decrease in the initial velocity of the ball core resulting from the inclusion of additives can be held to a minimum. | ||||||

| A rubber composition for golf balls includes (I) a base rubber, (II) an unsaturated carboxylic acid and/or a metal salt thereof, (III) a crosslinking initiator, and (IV) cellulose nanofibers. This rubber composition can further improve the durability of the ball without requiring the use of high-cost fibrous substances as compounding ingredients. Also, the steps in preparation of the golf ball rubber composition can be carried out smoothly and easily, making the rubber composition and its method of preparation economically and industrially advantageous. Moreover, the cellulose nanofibers used in this invention are a plant-based sustainable resource material, and so use of an environmentally friendly golf ball material becomes possible. | ||||||

| A golf ball is provided that includes at least two layers of material disposed between a spherical core and a cover layer, wherein the elastic modulus of each is within three orders of magnitude of each adjacent layer or core. The spherical core can be a hollow metal core. This results in a golf ball that is legal for play and capable of drive distances essentially equivalent to those of currently available high performance golf balls, but also provides a golf ball that has less hook and slice during play. | ||||||

| A device to function as a training aid designed to improve the tennis serves, ground strokes and volleys, badminton serves and strokes, volley ball serves and returns, baseball batting, racquet ball serves and returns, and squash serves and returns. It is also useful in any activity where the user seeks to improve striking performance when a sports object is suspended in a particular three-dimensional space location. | ||||||

| Disclosed herein is a composition for use in the preparation of a Lacrosse sport ball, the composition comprising a prepolymer, the prepolymer comprising a multifunctional polyisocyanate and one or more polyols having a molecular weight of from about 1000 Daltons to about 5000 Daltons, and a curative comprising an amine or an additional polyol or a combination thereof. A Lacrosse ball formed from the composition exhibits a ball compression of from about 180 pounds to about 210 pounds or from about 90 pounds to about 210 pounds when tested in accordance with ND 049-12m12 Section 5.3 Ball Compression, and wherein the molded spherical ball exhibits a ball coefficient of restitution COR of from about 0.60 to about 0.70 or from about 0.50 to about 0.75 when tested in accordance with ND 049-12m12 Section 5.4 Ball Coefficient of Restitution COR. | ||||||

| Apparatus and methods are provided for activity accessory including an energy harvester or generator. In an example, an activity accessory can include a first enclosure and an energy generator enclosed within the first enclosure. The energy generator can include a second enclosure. The energy generator can include a spherical magnet housed within the second enclosure and windings surrounding the second enclosure. Movement of the spherical magnet within the second enclosure can induce charge movement in the windings. | ||||||
