摘要： A contactless power supply is provided. The contactless power supply includes two or more primary coils for generating a region of cooperative magnetic flux generally therebetween. A portable device having a secondary coil can be positioned proximate this region of magnetic flux to receive wireless power from the contactless power supply. The spaced-apart primary coils can be wound in alternating directions about a common axis and driven in phase, or can be wound in a single direction about a common axis and driven approximately 180 degrees out of phase. The contactless power supply can include a plurality of primary coils in an adjustable array to accommodate multiple portable devices each with different secondary configurations and power consumption needs.

摘要： A selectively controllable electromagnetic shield having an electromagnetic shielding material and a mechanism for selectively generating an aperture in the shield. The mechanism for selectively generating an aperture may be a magnetic field source that generates a magnetic field of sufficient strength to substantially saturate all or a portion of the shielding material. For example, a permanent magnet or DC electromagnet may be used to selectively saturate the shield. In its un-saturated state, the magnetic shield has a high permeability and functions as a flux path for the magnetic field. Once saturated, the permeability of the shield is substantially reduced so that the magnetic field lines are no longer drawn into the shield to the same degree. As a result, once saturated, a substantially greater amount of the electromagnetic field may flow through or around the shield in the saturated region.
