The objective of the present invention is to provide a stability ball case configured to store a stability ball therein and, especially, having a weight thereon to prevent the stored stability ball from rolling, thereby avoiding a safety accident that may happen when the stability ball rolls and drops, as well as storing the stability ball at a desired place in a safe and convenient manner. particularly, another objective of the present invention is to provide a stability ball case configured such that a weight can be attached to and detached from a body constituting the case, whereby the weight can be separated from the body when the case is washed, or when the stability ball is carried, thereby enabling the stability ball case to be safely used and stored, as well as being conveniently used.

A basketball configured for organized, competitive play and having a total mass. The basketball includes an inflatable, generally spherical bladder, a set of winding surrounding the bladder, an elastomeric layer surrounding the set of windings and the bladder, and a plurality of cover panels positioned over the elastomeric layer. The bladder has a bladder mass that is greater than 25 percent of the total mass. The elastomeric layer and the set of windings have a collective mass that is less than 55 percent of the total mass.

Systems and methods for tracking a sports object are provided. A sports object includes a core assembly arranged within a shell and having multiple components to receive and transmit signals corresponding to movement of the sports object, as well as to support operational tracking of the sports object. The core assembly includes a multi-layer printed circuit board (PCB) comprised of a plurality of sections. The PCB is configured to at least partially envelope the energy storage device at a geometric center of the assembly. The PCB is connected to one or more antennas (e.g., via one or more contacts), which may be arranged on one or more sections of the PCB, arranged on a surface of the shell, and/or in a volume within the shell.

A ball includes a first housing, at least a fixing body, at least a ceramic vibration unit and a second housing. The fixing body is disposed on the internal wall of the first housing. The ceramic vibration unit is configured to make a sound and is fixed on the fixing body. The ceramic vibration unit includes a vibrating plate, a ceramic sheet and a cover body. The ceramic sheet and the cover body are disposed on the vibrating plate, and the ceramic sheet is located between the vibrating plate and the cover body. The second housing covers the first housing.

A lighting bounce ball comprises a bouncy hollow ball body a light source, and a cover layer. One end of the ball body is communicated with a nozzle and the other end thereof opposite to the nozzle is concavely formed a cup body. The nozzle and the cup body are coaxially arranged. The light source is concavely arranged in the cup body. The cover layer covers an outer surface of the bouncy hollow ball body and the cup body so that the nozzle is partially exposed externally to the bouncy hollow ball body. The ball may be lighted while playing so as to make much funner and attract the younger to play. In addition, the track of the ball may be obviously seen in the dark or a place with insufficient light. It may be used in more adaptable places.

Embodiments of the invention broadly contemplate systems, methods, apparatuses and program products that provide position tracking using a simple, low frequency oscillator that is attached to an object to be tracked, and one or more receiving stations that are placed around the area in which the object moves. Embodiments of the invention enable position tracking of the object using light weight equipment which minimally impacts the object's natural state.

A sport ball with a casing that forms at least a portion of an exterior surface of the sport ball; a bladder located within the casing, the bladder having a radially outward- facing surface oriented facing away from a center of the sport ball, and a radially inward-facing surface facing toward the center of the sport ball; a plurality of weighted areas disposed on the radially inward-facing surface of the bladder, wherein one or more of the plurality of weighted areas includes a feature; and a component located on the bladder.

A sport ball with a casing forming at least a portion of an exterior surface of the sport ball; a bladder disposed within the casing, the bladder having a radially outward-facing surface oriented facing away from a center of the sport ball, and a radially inward-facing surface facing toward the center of the sport ball; a valve integrally form with the bladder, wherein the valve includes a valve area on the bladder; and a restriction structure disposed between the casing and the bladder, the restriction structure comprised of a first material and a second material, wherein the second material is different from the first material.

This ball for ball game includes: a spherical skin portion formed to be transparent at least partially so that inside of an internal space is visible from outside; a tubular retention portion provided in the internal space and extending so as to connect two poles of the skin portion, the tubular retention portion having a surrounded space therein; and a retained object retained in a visible state between the two poles in the surrounded space. The tubular retention portion has a shape helically twisted between the two poles. The tubular retention portion is twisted with an angle not less than 135 and not greater than 270 between the two poles.
