Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 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.
