Inflatable ball containing electronic devices

An inflatable ball with integrated electronics, the inflatable ball comprising:

• a bladder defining an inflatable interior of the ball;
• an electronics casing attached to, or integrally formed with, the bladder, the electronics casing defining a compartment adjacent an inner surface of the inflatable interior of the ball and sealed within the inflatable interior of the ball;
• and
• 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;
• and
• wherein the electronics casing defines an electronics casing opening into the compartment for inserting the at least one electronic component, wherein the electronics casing opening faces an exterior of the bladder and is sealed by a sealing member, wherein the sealing member is an airtight layer extending over the electronics casing opening and sealed to the bladder or electronics casing, wherein prior to sealing by arrangement of the sealing member over the electronics casing opening, the electronics casing opening opens through to an exterior side of the bladder, such that the at least one electronic component may be inserted into the compartment from an exterior of the bladder;
• wherein
• the bladder contains a bladder opening for receiving the electronics casing, the electronics casing being attached to the bladder about the periphery of the bladder opening.
