Abstract: 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.

Abstract: An apparatus for insertion into an inflatable sports ball, the apparatus comprising a plate comprising a valve wherein the valve comprises an aperture for selective communication of air, a circuit board comprising a transmitter and a battery electrically connected to the circuit board.

Abstract: At least one device is mounted on or over the bladder wall of an inflatable ball such that a center of mass of the device is located away from a center of the inflatable interior of the ball. The device includes an electronic device. The center of mass of the device defines a first point on the bladder wall coincident with or closest to the center of mass of the device and a second point on the bladder wall opposite the first point. The ball comprises a distributed balancing mass for at least partially rotationally balancing the mass of the device. The distributed balancing mass comprises one or more balancing mass elements on or over the bladder wall. The balancing mass elements are arranged at a plurality of locations spaced around the second point on the bladder wall and closer to the second point than the first point.
