Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is related to and claims priority benefits from U.S. Provisional Application No. 61/998,687 having a filing date of Jul. 7, 2014, entitled “After Hours Sportsman Illumination Balls for Kids”. The '687 application is hereby incorporated in its entirety by reference.

FIELD OF THE INVENTION

The present invention relates to illumination systems for sports balls and, in particular, illumination systems that enhance visibility of sports balls, and perception and understanding of their motion in individual and team athletic activities.

BACKGROUND OF THE INVENTION

Sports balls are used in a variety of individual and team athletic activities including sports such as soccer, football, baseball, basketball, tennis and the like.
It can be desirable to enhance the visibility of a sports ball, for example in low light conditions, or to make the sports ball more readily distinguishable against a background to players and/or spectators.
In enhancing the visibility of the sports ball, it is desirable not to affect the flight of the ball, or the handling of the ball by the player.
Conventional approaches of enhancing the visibility of sports balls typically use colors and/or patterns marked on the surface of the sports balls.
In one example, a casing of a ball such as a soccer ball is produced in a first color, and a graphic of a second color positioned on the casing of the ball so as to improve visual acuity. Benefits of improved visual acuity include the ability of a player to recognize the ball more readily (for example, in the player's peripheral vision) and the ability to track the flight or movement of the ball more accurately.
In another example, a ball such as a football is circumscribed with contrasting indicia, configured such that a visually distinctive image can be observed when the ball executes a predetermined motion, for example rotation about a longitudinal or transverse axis.
In another approach, a soccer ball is provided with one or more internal LED lamps to make the ball glow in the dark. The lamps can be triggered to switch on when the ball is kicked and to stay illuminated for a predetermined period of time. In yet another example, the LED lamps can be switched on and off manually.
Conventional sports ball designs generally do not include an intelligent illumination system such as a system that can control the brightness, color, and temporal and spatial patterns of illumination, for example, according to the player's needs or in response to the motion of the ball. A benefit of a sports ball comprising an intelligent illumination system would be improved visual acuity in relation to the ball and more effective indication of the trajectory and motion of the ball.

SUMMARY OF THE INVENTION

An illuminated sports ball can be used for both recreational purposes and to aid in teaching and training athletes. The ball has at least one interior light source, a power source and at least one window from which the light source(s) can be seen.
In some embodiments the power source is a rechargeable battery that can be charged wirelessly via induction charging. In other embodiments the source is charged via linear inductive charging. Solar panels located on the ball can also be used to charge the power source.
In at least one embodiment the ball has an accelerometer. Data from the accelerometer can be used to determine how hard a user has kicked, thrown, and/or thrown the ball and can change the color of the light source to allow the user to visually see this information. In other or the same embodiments, the data from the accelerometer can be used to determine the type of spin being placed on the ball and change the color of the light source accordingly.
In some embodiments the ball can be configured to work with a monitoring system so that it can indicate, for example by a change in color of its light source, when it goes past a predetermine boundary, for example a goal line. The monitoring system can also record how hard the ball is being kicked, thrown, and/or hit by recording and/calculating either the ball trajectory and/or data received from an accelerometer.
