US Patent 10477741 Communication enabled EMF shield enclosures

An inductive power transmission system electromagnetic field shielding apparatus includes an enclosure. The enclosure is configured to surround an electronic device and an inductive power transmitter that inductively transmits power to the electronic device. A communication window or high pass filter is formed in the enclosure. The communication window may include an arrangement of one or more conductive materials defining one or more apertures. The enclosure and the communication window block passage of magnetic flux generated by the inductive power transmitter. The communication window allows passage of communication transmissions associated with the electronic device.
