Systems and methods of object detection using one or more sensors in wireless power charging systems

A wireless power transmission system comprising:

• a first wireless power transmitter configured to transmit electromagnetic wireless power transmission waves to a wireless power receiver located in a transmission field;
• one or more first sensors configured to capture first data of the transmission field, the first data identifying at least one object within the transmission field;
• and
• a controller configured to:
• determine whether a path between the wireless power receiver located in the transmission field and the first wireless power transmitter is unobstructed by the at least one object based, at least in part, on the first data;
• and
• in accordance with a determination that the path between the wireless power receiver and the first wireless power transmitter is unobstructed by the at least one object:
• instruct the first wireless power transmitter to transmit the electromagnetic wireless power transmission waves to the wireless power receiver using the path, wherein the wireless power receiver uses energy from at least some of the electromagnetic wireless power transmission waves to power or charge an electronic device coupled to the wireless power receiver.

An electronic device for managing a wireless power transmission system, the electronic device comprising:

• one or more processors;
• and
• memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for:
• receiving, from one or more first sensors, first data of a transmission field, the first data identifying at least one object within the transmission field, wherein a first wireless power transmitter is configured to transmit electromagnetic wireless power transmission waves to a wireless power receiver located in the transmission field;
• after receiving the first data, determining whether a path between the wireless power receiver located in the transmission field and the first wireless power transmitter is unobstructed by the at least one object based, at least in part, on the first data;
• and
• in accordance with a determination that the path between the wireless power receiver and the first wireless power transmitter is unobstructed by the at least one object:
• instructing the first wireless power transmitter to transmit the electromagnetic wireless power transmission waves to the wireless power receiver using the path, wherein the wireless power receiver uses energy from at least some of the electromagnetic wireless power transmission waves to power or charge an electronic device coupled to the wireless power receiver.
