Abstract
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.

8. An electromagnetic field shielding apparatus, comprising:
-
connected walls; and a grid including conductive material formed in at least one of the connected walls that blocks passage of frequencies below a threshold and allows passage of frequencies equal to or above the threshold;
wherein;magnetic flux produced by an inductive power transmitter has a first frequency below the threshold and is blocked; a communication transmission transmitted or received by a communication component has a second frequency equal to or above the threshold and is allowed; the electromagnetic field shielding apparatus is operable to transition between a first configuration and a second configuration; the electromagnetic field shielding apparatus is operable to at least partially enclose an electronic device in the first configuration; and the electromagnetic field shielding apparatus defines an opening in the second configuration though which the electronic device can be inserted into the electromagnetic field shielding apparatus or removed from the electromagnetic field shielding apparatus. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An enclosure, comprising:
-
metal walls configured to at least partially surround an electronic device; and a high pass filter formed by apertures defined by edges in the metal walls;
whereinthe high pass filter attenuates electromagnetic frequencies below a threshold to block passage of magnetic flux produced by an inductive power component and allow communication transmissions transmitted or received by a communication component; and the threshold corresponds to distances between the edges of the metal walls across the apertures. - View Dependent Claims (16, 17, 18, 19, 20)
