Abstract

Disclosed herein are systems, methods, and devices using an improved wireless communications component that allows for real time or near-real time data sampling reporting between devices using modified wireless communications protocols (e.g., Bluetooth®, Wi-Fi), and real time or near-real time behavior adjustments by a first device based on the data samples received from a second device. Embodiments disclosed herein comprise devices, such as receivers and transmitters, having communications components that may communicate data samples, such as power values, in real time or near-real time, thereby allowing a first device (e.g., transmitter) to adjust in real time or near-real time operational behavior of the first device'"'"'s hardware or software (e.g., adjust power waves) based upon the data samples (e.g., power values) received from a second device (e.g., receiver).

Claims

1. A method for wireless power transmission comprising:

receiving, by a communications component of a receiver, from a transmitter a first request for one or more power values associated with one or more power waves;

continuously and consecutively transmitting, by the communications component of the receiver, one or more power messages containing a power value associated with the one or more power waves; and

upon determining that a set of one or more buffers of the communications component of the receiver is unavailable;

transmitting, by the communications component of the receiver, at least one message containing an indicator bit indicating that the set of one or more buffers are full; and

resetting, by the communications component of the receiver, at least one buffer memory in the set of one or more buffers of the communications component upon receiving a second request for one or more power values from the transmitter.

2. The method according to claim 1, wherein the indicator bit is configured to instruct the transmitter to transmit the second request for the one or more power values associated with the one or more power waves.

3. The method according to claim 1, further comprising:

receiving, by an antenna of the receiver, the one or more power waves from the transmitter; and

converting, by the receiver, the one or more power waves to electrical power.

4. The method according to claim 3, further comprising continuously and consecutively determining, by the receiver, a power value associated with an amount of energy received from the one or more power waves.

5. The method according to claim 4, further comprising continuously and consecutively determining, by the receiver, a power value indicating an amount of energy converted to electrical power from the one or more power waves.

6. The method according to claim 3, wherein transmitting the one or more power messages further comprises:

generating, by the communications component of the receiver, the power message containing the power value associated with one or more power waves.

7. The method according to claim 6, wherein transmitting the one or more power messages further comprises:

storing, by the communications component of the receiver, each consecutive power message containing the power value into at least one output buffer memory of the set of one or more buffers of the communications component of the receiver.

8. The method according to claim 1, wherein the communications component of the receiver determines whether the set of one or more buffer memories are full upon transmitting each consecutive power message.

9. The method according to claim 1, wherein resetting the at least one buffer memory further comprises deleting the one or more power messages in the least one buffer memory.

10. The method according to claim 1, wherein resetting the at least one buffer memory further comprises restarting an address counter for the set of one or more buffer memories.

11. The method according to claim 1, wherein the communications component of the receiver is configured to communicate with a communications component of the transmitter over a communications signal independent of the one or more power waves.

12. The method according to claim 1, wherein the communications component of the receiver comprises one or more chips configured to communicate using a Bluetooth®

wireless communications protocol.

13. A wireless charging receiver device comprising:

a communications component comprising;

a set of one or more buffer memories configured to store one or more power messages containing one or more power values; and

a processor configured to continuously and consecutively transmit to a transmitter the one or more power messages until determining that the set of one or more buffer memories are filled, and upon determining that the set of one or more buffer memories are filled, transmit an indicator bit to the transmitter and reset the set of one or more buffer memories; and

a processor configured to continuously and consecutively determine a power value associated with one or more power waves for each consecutive power message generated by the communication component.

14. The device according to claim 13, wherein the indicator bit instructs the transmitter to transmit a second request for the one or more power values.

15. The device according to claim 14, wherein the communications component of the receiver is further configured to reset the set of one or more buffer memories upon receiving the second request from the transmitter.

16. The device according to claim 13, further comprising:

an array of one or more antennas configured to capture energy from the one or more power waves; and

at least one circuit configured to convert the RF energy from the one or more power waves to electrical power.

17. The device according to claim 16, wherein the processor of the receiver is further configured to determine at least one power value based upon an amount of energy captured from the one or more power waves.

18. The device according to claim 16, wherein the processor of the receiver is further configured to determine at least one power value based upon an amount of energy converted to electrical power.

19. The device according to claim 13, wherein the communications component of the receiver is configured to communicate with a communications component of the transmitter over a communications signal independent of the one or more power waves.

20. The device according to claim 13, wherein the communications component of the receiver comprises one or more chips configured to communicate using a Bluetooth®

wireless communications protocol.
