Abstract

A valve for a ball includes a casing and a core. The core is arranged at least partially inside the casing. The core comprises a first sealing area with a plurality of sections which have alternating concave and convex curvatures.

Claims

1. A ball comprising:

a valve comprising a valve casing and a valve core at least partially disposed inside the valve casing;

an electromagnetic coil disposed about an inner end of the valve casing;

an energy storage configured to be inductively charged by the electromagnetic coil; and

an electronic device coupled to the energy storage.

2. The ball of claim 1, wherein the electromagnetic coil is disposed in a recess of the valve casing.

3. The ball of claim 1, wherein the electronic device is a sensor.

4. The ball of claim 1, wherein the electronic device is a sensor for measuring the position of the ball.

5. The ball of claim 1, wherein the electronic device is a sensor for measuring the motion of the ball.

6. The ball of claim 1, wherein the electronic device is an acceleration sensor.

7. The ball of claim 1, wherein the electronic device is a pressure sensor.

8. A ball comprising:

a bladder;

a valve coupled to the bladder and comprising a valve casing and a valve core at least partially disposed inside the valve casing;

an electromagnetic coil disposed within a tunnel of the bladder;

an energy storage configured to be inductively charged by the electromagnetic coil; and

an electronic device coupled to the energy storage,

wherein the electromagnetic coil is disposed on the bladder in a circular arrangement around the valve.

9. The ball of claim 8, wherein the electronic device is a sensor.

10. The ball of claim 8, wherein the electronic device is a sensor for measuring the position of the ball.

11. The ball of claim 8, wherein the electronic device is a sensor for measuring the motion of the ball.

12. The ball of claim 8, wherein the electronic device is an acceleration sensor.

13. The ball of claim 8, wherein the electronic device is a pressure sensor.

14. A ball comprising:

a bladder;

a valve coupled to the bladder;

an electromagnetic coil coupled to the bladder;

an energy storage configured to be inductively charged by the electromagnetic coil; and

an electronic device coupled to the energy storage and disposed at an opposite side of the bladder from the electromagnetic coil,

wherein the electromagnetic coil is disposed on the bladder in a circular arrangement around the valve.

15. The ball of claim 14, wherein the electromagnetic coil is formed of a wire having a thickness and a number of windings, and

wherein the thickness and the number of windings is based on a weight of the electronic device.
