An electronically trackable ball consisting of a cover, an inflatable bladder, a valve in the bladder a mounting structure attached to said valve and extending inwardly of the valve toward the center of the inflated bladder and an electronic transmission device on said mounting structure remote from said valve. The mounting structure is preferably a lightweight polymeric cylinder with the electronics fitted at the end remote from the valve and close to the center of mass of the ball. The device is within the ball, and is constrained from moving around inside the ball.

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.

A luminous ball includes a light-transmittance inner airbag, a light-transmittance outer surface layer, a light-emitting assembly and a cover body. The light-transmittance inner airbag defines an inflation space. An accommodating slot is provided in the light-transmittance inner airbag. The outer wall of the accommodating slot extending into the inflatable space from the outside. The light-transmittance outer surface layer is wrapped around an outer surface of the light-transmittance inner airbag. The light-transmittance outer surface layer is provided with a first opening. The light-emitting assembly is detachably inserted into the accommodating slot. The cover body is in detachable threaded connection to an inner wall of the accommodating slot and covers the accommodating slot to limit the light-emitting assembly in the accommodating slot. The cover body is in detachable to the accommodating slot and covers the accommodating slot to limit the light-emitting assembly in the accommodating slot.

An inflatable ball with integrated electronics and a method of manufacture. The inflatable ball comprises a bladder defining an inflatable interior of the ball and an electronics casing attached to, or integrally formed with, the bladder. The electronics casing defines a compartment adjacent an inner surface of the inflatable interior of the ball and sealed within the inflatable interior of the ball. The inflatable ball further comprises at least one electronic component, wherein the electronic component is located within the compartment of the electronics casing; and wherein the compartment is in fluid communication with the inflatable interior of the ball such that the compartment is at the same pressure as the inflatable interior of the ball.
