Abstract

A system and method for determining a re-configuration of a wireless surface with a multi-coil system are provided. The system includes a reference generator to determine a reference parameter associated with the wireless surface; a recheck initiator to instigates a re-measurement; a re-measurer, in response to the initiated re-measurement, to measure a parameter associated with the reference parameter; and an analyzer to retrieve a determination about the wireless surface based on a difference between the measured parameter and the measured reference parameter.

Claims

1. A system for determining a re-configuration of a wireless surface with a multi-coil system, comprising:

a data store comprising a computer readable medium storing a program of instructions for the determination of the re-configuration;

a processor that executes the program of instructions;

a reference generator to determine a reference parameter associated with the wireless surface;

a recheck initiator to instigates a re-measurement;

a re-measurer, in response to the initiated re-measurement, to measure a parameter associated with the reference parameter; and

an analyzer to retrieve a determination about the wireless surface based on a difference between the measured parameter and the measured reference parameter, and

wherein the measured parameter is correlated to a predetermined alignment amount for each coil of the multi-coil system, and based on a determination of which one of the each coils is correlated to a lowest predetermined alignment amount, the determined which one of the coils is switched on to provide wireless power, and the non-determined coils are switched off to not provide wireless power.

2. The system according to claim 1, wherein the reference parameter is frequency.

3. The system according to claim 1, wherein the reference parameter is voltage.

4. The system according to claim 1, wherein the reference parameter is current.

5. The system according to claim 1, wherein the re-check initiator instigates the re-measurement based on a predetermined time interval.

6. The system according to claim 1, wherein the re-check initiator instigates the re-measurement based on a stimulus.

7. The system according to claim 1, wherein the reference parameter further comprises at least a first reference parameter, a second reference parameter, and a third reference parameter, and the first reference parameter is frequency, the second reference parameter is voltage, and the third reference parameter is current.

8. The system according to claim 7, wherein the wireless surface comprises a plurality of coils, and the determination correlates to whether the electronic device is aligned or misaligned.
