One or more devices, methods, and systems implementing one or more techniques for use of one or more sport balls and/or evaluations of handling one or more sport balls are disclosed. One or more techniques may include a sport ball having one or more pressure sensors configured to generate one or more force values between the one or more pressure sensors and a sport ball user upon use/engagement of the sport ball with the user. One or more techniques may include a processor configured to determine at least one handling value, perhaps based upon the one or more force values.

A sports ball and a method of manufacturing the same are provided. The sports ball having a bladder, an outer cover layer, and an intermediate structure disposed between the outer cover layer and the bladder. The intermediate structure includes a restriction structure comprising a plurality of overlapping layers of cross-linked polymer film wrapped about the bladder. The sports ball may be formed via the steps of surrounding the bladder, having a first initial circumferential dimension, with a plurality of overlapping layers of cross-linked polymer shrink film, such that the cross-linked shrink film forms a restriction structure in a first dimensional state; applying a heat shrinking process to the cross-linked polymer shrink film to contract the restriction structure from the first dimensional state to a second dimensional state; inflating the bladder to a second circumferential dimension; and disposing the outer cover layer and intermediate layers about the bladder and restriction structure.

A bouncy ball includes anomalies which, when bounced upon, causes the ball to bounce irregularly. The anomaly may comprise a solid protrusion formed integrally with an outer skin of the ball or a separate plug filled into a pocket formed in the outer skin. The shape of the protrusion may be partially spherical. The solid protrusion may also include elongate grooves, flat surfaces or any other desired shape, such as a star. The bouncy ball may also include a secondary bladder with inflatable anomalies. The secondary bladder is coupled to a generally spherical inner tube which may be formed with grooves to receive the secondary bladder. Outer skins may be coupled over the secondary bladder and inner tube.

The present invention relates to a ball structure and a method for making the same. The ball structure includes an inner bladder and a plurality of covers. The covers surround the inner bladder. Each of the covers includes a base fabric and a resin layer. The resin layer has a recess portion at the periphery of the cover, so that the recess portions of adjacent covers defines a groove. The base fabric includes a first portion and a second portion. The first portion corresponds to the recess portion, and the second portion is away from the recess portion. The thickness of the first portion is substantially equal to the thickness of the second portion.

A basketball and method wherein the present invention provides establishment of a new size category for basketballs that is greater than the upper limit of the current size category range. The basketball of the present invention is manufactured similarly to existing basketballs wherein the basketball has an inner bladder wrapped in either polyester or nylon threads. The basketball has an outer covering manufactured from leather or rubber. The basketball of the present invention is formed to have a circumference that measures thirty inches. The method of the present invention provides establishment of a new size category of basketballs that is greater than the existing largest size category. Establishment of the new size category is executed through submission to regulatory authorities. The basketball of the present invention establishes a new size category of the size eight.

A method of manufacturing an article comprises etching an etched feature on a surface of a first polymeric sheet, and forming a fluid-filled bladder element from the first polymeric sheet, with the fluid-filled bladder element having a sealable internal cavity that retains fluid. The method includes assembling the bladder element in the article so that a first portion of the bladder element having the etched feature is exposed to view, and a second portion of the bladder element is blocked from view by the article. An article includes the bladder element with the etched feature.
