Inductive charging keyboard
First Claim
1. A device, comprising:
- a keyboard comprising one or more keycaps;
one or more inductive charging coils, each of the one or more inductive charging coils being disposed within a corresponding keycap of the one or more keycaps;
a charge control circuit electrically coupled to the one or more inductive charging coils, the charge control circuit configured to control one of (a) an electrical current provided to the one or more inductive charging coils and (b) an electrical current provided from the one or more inductive charging coils to a rechargeable battery of the device;
wherein the one or more inductive charging coils disposed within the one or more keycaps are configured to perform;
transmitting a wireless charging signal to one or more inductive charging coils of a secondary device positioned above the keyboard, the wireless charging signal recharging a rechargeable battery of the secondary device; and
receiving a wireless charging signal from a secondary device positioned above the keyboard, and recharging the rechargeable battery of the device using the wireless charging signal.

Abstract
Aspects of the disclosure relate to a wireless charging device having an inductive charging coil built into a keyboard, such as the interior space of a keycap in the keyboard. The wireless charging device and keyboard may further be built into a housing of a primary device, such as a laptop computer. The wireless charging device may communicate with another secondary device having a compatible coil. For example, the wireless charging device may transmit, via the inductive charging coil, a wireless charging signal to a wirelessly chargeable device placed on top of the keyboard. In another example, the wireless charging device may receive, through the inductive charging coil, a wireless charging signal from a wireless powering device placed on top of the keyboard.

13. A method for executing a wireless charging routine, the wireless charging routine including at least one of (i) transmission of a wireless charging signal from a first device to a second device, and (ii) receipt of a wireless charging signal at a first device from a second device, wherein the first device comprises a power source, a keyboard comprising one or more keycaps, and one or more inductive charging coils disposed within corresponding keycaps of the one or more keycaps, the method comprising:
-
receiving, at the first device, a wireless request signal; determining, at the first device, whether the wireless request signal is a request to wirelessly charge the first device or a request to receive a wireless charge from the first device; selecting, at the first device, with which of the one or more inductive charging coils to execute the wireless charging routine; if the wireless request signal is a request to wirelessly charge the first device, receiving a wireless charging signal at the selected one or more inductive charging coils disposed within the one or more keycaps and relaying a current generated in the selected one or more inductive charging coils to the power source; and if the wireless request signal is a request to be wirelessly charged by the first device, supplying an amount of current from the power source to the selected one or more inductive charging coils disposed within the one or more keycaps, and generating a wireless charging signal at the selected one or more inductive charging coils. - View Dependent Claims (14, 15, 16, 17, 18)

19. A system comprising:
-
a first device comprising; a keyboard comprising one or more keycaps; one or more inductive charging coils, each of the one or more inductive charging coils being disposed within a corresponding keycap of the one or more keycaps; a charge control circuit electrically coupled to the one or more inductive charging coils, the charge control circuit configured to control (a) an electrical current provided to the one or more inductive charging coils disposed within the one or more keycaps and (b) an electrical current provided from the one or more inductive charging coils disposed within the one or more keycaps to a rechargeable battery of the first device; and a second device configured for communicating with the first device, the second device comprising; one of a power source, a power source input, and a rechargeable battery; one or more inductive charging coils configured for transmitting or receiving a wireless charging signal to or from the first device when the second device is positioned above the keyboard. - View Dependent Claims (20)
