SELECTING A CONFIGURATION OF COILS IN RESPONSE TO A MULTI-COIL WIRELESS CHARGING SYSTEM INITIATING CHARGING
First Claim
1. A system for selecting a configuration of coils in response to a multi-coil wireless charging system initiating charging, comprising:
- a data store comprising a computer readable medium storing a program of instructions for the selecting of the configuration;
a processor that executes the program of instructions;
a ping generator to measure a reference coil peak voltage for each of the coils of the multi-coil wireless charging system;
an object detector to detect that an object is placed on a surface associated with the wireless charging system;
a charge detector to detect that the object is chargeable; and
in response to the object being chargeable, a switch transmitter determines which of the coils of the multi-coil wireless charging system to connect to a power source.

8. A method implemented via a processor for selecting a configuration of coils in response to a multi-coil wireless charging system initiating charging, comprising:
-
determining a reference coil peak voltage for each of the coils; polling the coils to measure a coil peak voltage associated with each of the coils; determining if a difference exists between the reference coil peak voltage and the measured coil peak voltage; in response to the difference existing, determining whether an object is placed on a surface of the wireless charging system, and determining whether the object is a chargeable device based on the difference; and selecting a switch associated with one of the coils based on the difference. - View Dependent Claims (9, 10, 11, 12, 13, 14)
