Abstract

There is provided a system that includes a base providing a wireless power source, a rotor situated over the base and configured to spin, and a device coupled to the rotor and configured to spin with the rotor, the device having a display and a wireless power receiver, where the wireless power source and the wireless power receiver are configured to power the device to show an image on the display while the rotor is spinning.

First claim

What is claimed is:

1. A system comprising:
a base providing a power source;
a rotor configured to spin;
a device including a battery, the device coupled to the rotor and configured to spin with the rotor; and
a power receiver electrically connected to the battery;
wherein the power receiver is configured to receive power from the power source and charge the battery using the power when a spin rate of the rotor is below or equal to a predetermined spin rate, and wherein the power receiver is configured to stop receiving the power from the power source when the spin rate of the rotor is above the predetermined spin rate.

2. The system of claim 1 , wherein the power receiver is configured to make electrical contact with the power source so as to charge the battery.

3. The system of claim 1 , wherein the power source is configured to provide the power to the power receiver using resonant magnetic induction.

4. The system of claim 1 , wherein the power source is configured to provide the power to the power receiver using non-resonant magnetic induction.

5. The system of claim 1 , wherein the power source is configured to provide the power to the power receiver using radio frequency (RF) power transmission.

6. The system of claim 1 , wherein the power source is configured to provide the power to the power receiver by making an electrical contact with the power receiver.

7. The system of claim 6 , wherein the power source comprises a substantially circular power rail concentric with the rotor and wherein the power receiver is configured to make the electrical contact with the substantially circular power rail so as to charge the battery when the spin rate of the rotor is below or equal to the predetermined spin rate, and to break electrical contact with the substantially circular power rail when the spin rate of the rotor is above the predetermined spin rate.

8. The system of claim 6 , further comprising:
a ground coupler electrically connected to the battery, wherein the ground coupler is configured to make ground contact with the power source when the spin rate of the rotor is below or equal to the predetermined spin rate, and to break ground contact with the power source when the spin rate of the rotor is above the predetermined spin rate.

9. The system of claim 1 , wherein the device comprises a display screen.

10. The system of claim 1 , wherein the device is an object.

11. The system of claim 1 , wherein the predetermined spin rate is zero.

12. The system of claim 1 , wherein the power receiver is situated over the power source.
