Contactless power supply apparatus, contactless power receiving apparatus, and associated methodology of priority display
First Claim
1. A contactless power supply apparatus that emits AC power using magnetic field resonance, comprising:
- an AC power supply to generate an AC current;
at least one circuit to generate a magnetic field from the AC current generated by the AC power supply;
a charging surface to charge at least one device in physical proximity thereto using magnetic field resonance according to the magnetic field generated by the at least one circuit; and
a plurality of predetermined shapes concentrically arranged on the charging surface to indicate a charging priority relative to a center of the charging surface according to a magnetic field strength of the magnetic field.

Abstract
A contactless power supply for charging at least one device using magnetic field resonance includes an AC power supply, at least one circuit, a charging surface and at least one indicator to indicate a charging priority relative to the charging surface according to magnetic field strength. Devices placed near a region of the charging surface indicated as having a high priority by the indicators will charge more rapidly than an external device placed near a region of the charging surface indicated by the indicators as having a lower charging priority. Indication of the charging priority regions on the charging surface may be indicated by differing materials, patterns, shapes or offsets. In addition, the contactless power supply may have more than one region of high charging priority.
