Abstract: A golf ball may include an inner core layer and an outer cover layer disposed radially outward of the inner core layer. The outer cover layer may be formed of an outer cover layer material having one or more grooves extending radially inward from an outer surface of the outer cover layer. In addition, the golf ball may include a groove material disposed within the one or more grooves. The groove material may have a compressibility that is different from a compressibility of the outer cover layer material. Also, the outer surface of the groove material may be recessed below the outer surface of the outer cover layer.

Abstract: A golf ball is provided that includes a coating. The coating is designed to allow a golfer to modify or increase the tackiness of the coating. The coating changes tackiness when exposed to a soaking material. A method of determining a desirable length of soak is also disclosed.

Abstract: A method of making a golf ball may include molding at least one core layer and molding an outer cover layer radially outward of the at least one core layer, from an outer cover layer material, including forming one or more grooves extending radially inward from an outer surface of the outer cover layer. The method may also include molding a groove material within the one or more grooves, the groove material having a compressibility that is different from a compressibility of the outer cover layer material. In addition, molding the groove material may include forming the groove material such that an outer surface of the groove material extends radially outward beyond the outer surface of the outer cover layer.

Abstract: A method and system of subjective evaluation of golf ball performance for golf ball fitting analysis to match a golf ball to a golfer's subjective preferences is described. A golfer subjectively evaluates the performance of one or more golf balls against different subjective criteria. Analysis of the subjective evaluation is used to determine a golf ball that maximizes or most closely conforms to the golfer's subjective preferences. A kit of parts is provided to allow a golfer to subjectively evaluate multiple golf balls to each other to determine a golfer's preference or to recommend another golf ball. The kit includes different types of golf balls and a fitting tool that is used by the golfer to evaluate his or her subjective preferences. The fitting tool can be calibrated to the specific subjective perceptions of a golfer. The fitting tool can also be customized to a specific course.

Abstract: A golf ball includes an inner layer, a cover layer, and a cavity. The cavity includes a conduit connecting the cavity with an exterior of the golf ball. The cavity contains a matrix comprising particles of a first material bound together by a second material. The first material has a density greater than water and the second material is water soluble. Upon prolonged submersion in water, the matrix dissolves allowing the first material particles to exit the cavity. The removal of the mass of the first material particles lowers the density of the golf ball, allowing the golf ball to float to the surface of the water.

Abstract: A system and method for incentivizing recycling of collected products by providing both an incentive award and information about the post-recycling stream designation of the collected products to a user. The collected products are assigned a trace element which is machine readable data input, with scanners or detectors disposed along the recycling stream. Once a decision is made regarding the recycle designation for a collected product, that information is provided to the user. A computer program that stores and calculates the award could be used to calculate analogous or ancillary calculations regarding post-recycling designations to enable comparisons with other users and online competition.
