System and method for controlling communication between wireless power transmitter managers
First Claim
1. A system for selecting which power transmitter should deliver wireless power to a device in a wireless power delivery network, the system comprising:
- a first power transmitter communicatively coupled to at least one transmitter manager, the first power transmitter configured to detect, based on a short-range communication signal received from a user device, a first signal strength level for the user device, wherein the user device is coupled with at least one power receiver;
a second power transmitter communicatively coupled to the at least one transmitter manager, the second power transmitter configured to detect, based on a short-range communication signal received from the user device, a second signal strength level for the user device;
the at least one transmitter manager configured to;
in accordance with a determination that the first signal strength level remains above a first predetermined signal strength threshold for more than a minimum amount of time, provide the first power transmitter with control over transmission of one or more RF waves to the power receiver of the user device; and
in accordance with a determination that (i) the first signal strength level drops below a second predetermined signal strength threshold and (ii) the second signal strength level remains above the predetermined signal strength threshold for more than the minimum amount of time, provide the second power transmitter with control over transmission of one or more RF waves to the at least one power receiver of the user device,wherein the transmission of one or more RF waves produces a pocket of energy in proximity to the at least one power receiver and the at least one power receiver is configured to convert the one or more RF waves into usable power for charging the user device.

Abstract
A method for controlling communication between wireless power transmitter managers is disclosed. According to some aspects of this embodiment, wireless power transmission system may include one or more wireless power transmitter managers and one or more wireless power receivers for powering various customer devices. A WiFi connection may be established between wireless power transmitter managers to share information between system devices. Wireless power transmitter manager may need to fulfill two conditions to control power transfer over a customer device; customer device'"'"'s signal strength threshold has to be significantly greater than 50%, such as 55% or more of the signal strength measured by all other wireless power transmitter managers and has to remain significantly greater than 50% for a minimum amount of time.

14. A method for selecting which power transmitter should deliver wireless power to a device in a wireless power delivery network, the method comprising:
-
detecting, by a first power transmitter and based on a short-range communication signal received from a user device, a first signal strength level for the user device, wherein the user device is coupled with at least one power receiver; detecting, by a second power transmitter and based on a short-range communication signal received from the user device, a second signal strength level for the user device, wherein the first power transmitter and the second power transmitter are both communicatively coupled to at least one transmitter manager; in accordance with a determination, by the at least one transmitter manager, that the first signal strength level remains above a first predetermined signal strength threshold for more than a minimum amount of time, providing the first power transmitter with control over transmission of one or more RF waves to the power receiver of the user device; and in accordance with a determination, by the at least one transmitter manager, that (i) the first signal strength level drops below a second predetermined signal strength threshold and (ii) the second signal strength level remains above the predetermined signal strength threshold for more than the minimum amount of time, providing the second power transmitter with control over transmission of one or more RF waves to the at least one power receiver of the user device, wherein the transmission of one or more RF waves produces a pocket of energy in proximity to the at least one power receiver and the at least one power receiver is configured to convert the one or more RF waves into usable power for charging the user device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
