Operations with instrumented game ball

1. A method, comprising:

placing on an inductive charging device an athletic ball that comprises a battery, a shell having multiple layers including at least an outermost layer, a middle layer, and an innermost bladder layer, the outermost layer and the middle layer each extending integrally around the entire bladder layer, wherein either the middle layer or the bladder layer have a depression formed in a surface of the layer and a metallic coil set within the depression, and the bladder layer having a pocket holding the battery;

generating an electric or magnetic field, or both, with the inductive charging device;

receiving, by the metallic coil energy from the field or fields; and

charging the battery using the received energy.

2. The method of claim 1 , further comprising transmitting data wirelessly from the ball in response to sensing the inductive charging device.

3. The method of claim 1 , wherein the one or more coils include a plurality of coils in different hemispheres of the athletic ball so as to enable charging of the battery when the athletic ball is at different rotational angles in relation to the inductive charging device.

4. The method of claim 1 , wherein the one or more coils are formed integrally with a flexible printed circuit board.

5. An athletic game ball system, comprising:

a shell constructed from multiple substantially spherical concentric layers including at least an outermost layer, a middle layer, and an innermost bladder layer, the outermost layer and the middle layer each extending integrally around the entire bladder layer, wherein either the middle layer or the bladder layer have a depression formed in a surface of the layer;

one or more electronic sensors located within a pocket of the bladder; and

one or more inductive electric secondary charging coils located within the depression and connected to provide electrical energy to one or more energy storage devices connected to supply power for operating the one or more sensors.

6. The athletic game ball system of claim 5 , further comprising a circuit board located within the pocket supporting the electronic sensors and associated circuitry for monitoring motion of the game ball.

7. The athletic game ball system of claim 5 , wherein the one or more sensors comprise (i) an accelerometer, (ii) a magnetometer or angular rate sensor, and (iii) a near field communications sensor.

8. The athletic gaming ball system of claim 5 , wherein the one or more inductive electric secondary coils include a plurality of coils in different hemispheres of the ball so as to enable charging of the battery when the ball is at different rotational angles in relation to a charging base.

9. The athletic gaming ball system of claim 5 , wherein the one or more inductive electric secondary coils are formed integrally with a flexible printed circuit board.

10. The athletic gaming ball system of claim 5 , wherein the associated electronics are programmed to identify perturbations in an electric or magnetic field around the ball so as to identify when the ball has passed near a gaming goal.

11. A method of constructing an instrumented athletic game ball, the method comprising:

providing a ball bladder layer that is part of a shell of the game ball having a pocket;

providing an electronic sensor package in the pocket;

providing, outwardly of the ball bladder layer, a substantially spherical middle layer extending integrally around the entire bladder layer and having a depression formed in an outer surface of the middle layer;

applying within the depression of the surface of the middle layer one or more inductive charging coils;

connecting the one or more inductive charging coils to the electronic sensor package; and

providing a substantially spherical outermost layer extending integrally around the entire middle layer.

12. The method of claim 11 , wherein at least one of the one or more inductive charging coils is located to surround the pocket in the bladder.

13. The method of claim 11 , wherein the electronic sensor package includes a battery for powering components of the electronics sensor package and for receiving electrical charging power from the inductive charging coil.

14. The method of claim 11 , further comprising testing charging of the electronic sensor package via the one or more inductive charging coils to verify proper operation of the game ball.
