Abstract: A current sensor may include a sense element disposed proximate a conductor. The current sensor may be configured to couple to a first magnetic field generated at the conductor when current flows in the conductor. An output electrically connected to the sense element can produce a signal that is representative of the flow of current in the conductor. The sense element may be oriented in a plane parallel to magnetic field lines of a second magnetic field generated by a load connected to the conductor.

Abstract: A method and system for providing wireless power transfer through a metal object by forming a loop conductor from the metal object through a feature or component embedded within the metal object and by replacing portions of the metal object with insulating components. The method and system utilize a recessed channel to install and isolate conductors that are connected to transmitter or receiver circuits and enable wireless power transfer and other communications. The recessed channel creates a loop around at least a portion of the metal object such that the conductor installed therein may form a loop conductor, which may be connected to a source or sink. In some implementations, a logo embedded within the metal object may create a loop formed by the metal object with a current path around the logo, wherein the metal object itself may be configured to operate as the conductor.
