Inflatable ball containing electronic devices
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.
1 . 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.
2 . The inflatable ball according to claim 1 , wherein the electronics casing is formed as one integral piece.
3 . The inflatable ball according to claim 1 , wherein the electronics casing is fixed relative to the bladder.
4 . The inflatable ball according to claim 1 , wherein the at least one electronic component is fixedly attached to the electronics casing.
5 . The inflatable ball according to claim 1 , wherein the electronics casing comprises one or more perforations through the electronics casing so that the compartment of the casing is in fluid communication with the inflatable interior of the ball.
6 . The inflatable ball according to claim 1 , wherein the electronics casing substantially encloses the at least one electronic component located in the compartment.
7 . The inflatable ball according to claim 1 , wherein the at least one electronic component includes at least one accelerometer, gyroscope, or force sensor.
8 . The inflatable ball according to claim 1 , wherein the bladder further comprises an air valve for inflating the ball, the air valve being separated from the electronics casing by an area of bladder wall.
9 . The inflatable ball according to claim 1 , wherein the electronics casing is made of the same material as the bladder.
10 . The inflatable ball according to claim 1 , wherein the electronics casing is made of material having a Young's modulus not more than 50% higher than the Young's modulus of the material forming the bladder.
