Abstract
An article of furniture having an internal frame and an upholstery covering is provided with at least one transmitting resonator carried by said frame and disposed at least partially beneath said upholstery covering. The resonator is tuned for resonance at a predetermined frequency and driven by a high frequency power source also carried by said frame. The high frequency power source is adapted for coupling to a source of electric power external to the article of furniture, such as to an AC outlet. The high frequency power source and transmitting resonator producing in the near field adjacent the at least one transmitting resonator a magnetic field that couples and transfers power at the predetermined frequency. A complementary receiving resonator or a compound passive resonator having two or more coils is coupled to the load to be powered and power is transferred by magnetic induction when the receiving resonator is positioned within the near field of the transmitting resonator.
