SYSTEM AND METHOD FOR FREQUENCY PROTECTION IN WIRELESS CHARGING
First Claim
1. An apparatus for controlling wireless charging, comprising:
- a receiver communication circuit of a first entity configured to receive a current wirelessly from a second entity via electromagnetic induction during the charging or alignment with the second entity;
a frequency measurement circuit configured to determine an operating frequency of the received current or a voltage induced by the electromagnetic induction; and
a controller configured to compare the operating frequency to a threshold and adjust an operation of the charging or the alignment based on the comparison, the controller configured to adjust the operation via continuing the charging or the alignment in response to a difference between the operating frequency and the threshold being less than or equal to a first tolerance level, and via stopping or refusing the charging or the alignment in response to the difference being greater than the first tolerance level.

Abstract
This disclosure provides systems, methods, and apparatuses for controlling wireless charging between a first entity and a second entity. For example, the apparatus may include a receiver communication circuit of the first entity configured to receive a current from a second entity via electromagnetic induction during the charging or alignment with the second entity. The apparatus may include a frequency measurement circuit configured to determine an operating frequency of the received current or a voltage induced by the electromagnetic induction. The apparatus may include a controller configured to compare the operating frequency to a threshold and adjust an operation of the charging or the alignment based on the comparison.

22. An apparatus for controlling wireless charging between a first entity and a second entity, comprising:
-
means for receiving a current wirelessly from the second entity via electromagnetic induction during the charging or alignment with the second entity; means for determining an operating frequency of the received current or a voltage induced by the electromagnetic induction; means for comparing the frequency to a threshold; and means for adjusting an operation of the charging or the alignment based on the comparison, the means for adjusting comprising means for continuing the charging or the alignment in response to a difference between the operating frequency and the threshold being less than or equal to a first tolerance level, the means for adjusting further comprising means for stopping or refusing the charging or the alignment in response to the difference being greater than the first tolerance level. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
