1. A method for displaying visual signals associated with wireless power transmission, the method comprising:
- receiving a beacon signal from a client device in a wireless power delivery environment, wherein the beacon signal travels along one or more wireless paths between the client device and a wireless power transmitter in the wireless power delivery environment;
determining a direction to transmit power to the client device based, at least in part, on a detected phase of the received beacon signal;
transmitting wireless power to the client device in the determined direction; and
activating, in response to transmitting the wireless power to the client device, a light emitting diode (LED) or group of LEDs positioned to indicate the direction that the wireless power is transmitted.

Abstract
The disclosed technology relates to antenna configurations for wireless power transmission and supplemental visual signals. In some implementations, the disclosed technology includes a wireless power transmitter with boards that have multiple antennas physically coupled to the board. In some implementations, the antennas boards are arranged in a polygonal configuration (e.g., star shape). Additionally, in some implementations, the antennas can have different polarization configurations.

11. A wireless power transmission system comprising:
-
an antenna array having a plurality of radio frequency (RF) antennas; a plurality of light emitting diodes (LEDs) configured to indicate a direction that wireless power is transmitted from the wireless power transmission system; and control circuitry operatively coupled to the antenna array and the plurality of LEDs, the control circuitry configured to; detect, at one or more antennas of the multiple RF antennas, a beacon signal transmitted by a client device in a wireless power delivery environment, wherein the beacon signal traverses one or more paths between the client device and the wireless power transmission system in the wireless power delivery environment; determine a direction to transmit power to the client device based, at least in part, on a detected phase of the received beacon signal at the one or more antennas of the multiple RF antennas; direct the one or more antennas of the multiple RF antennas to transmit wireless power to the client device in the determined direction; and responsively activate an LED or group of LEDs of the plurality of LEDs to indicate the determined direction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An apparatus comprising:
one or more computer readable storage media having instructions stored thereon which, when executed by one or more processing systems of a wireless power transmission system, direct the wireless power transmission system to; dynamically determine a direction that the wireless power transmission system is transmitting wireless power to a client device in a wireless power delivery environment based, at least in part, on a phase of a received beacon signal detected at one or more of multiple RF antennas of the wireless power transmission system; and responsively activate an LED or group of LEDs of the plurality of LEDs to indicate the direction.
