Abstract:
1. A wireless power reception apparatus comprising: a reception coil configured to receive an electric power signal including any one of an electric field, a magnetic field, and an electromagnetic field transmitted from a power supply apparatus, wherein the electric power signal is frequency-modulated or otherwise phase-modulated according to a modulation signal corresponding to a given transmission-side code at the power supply apparatus; a resonance capacitor that, together with the reception coil, forms a resonance circuit; a control unit configured to change the impedance of the resonance circuit based upon a reception-side code that is to correspond to the transmission-side code used in the power supply apparatus such that resonance occurs between the resonance circuit and the electric power signal; and a reception unit configured to acquire the reception-side code by accessing a predetermined Internet site.
