Magnetic coupling device

摘要

A magnetic attachment comprises a stacked configuration including an attachment surface, a magnetic coupling device, and a device comprising at least one magnet. A thin non-conductive sheet may be positioned between the magnetic coupling device and the at least one magnet. The magnetic coupling device may include an aperture through which radio signals may pass. The magnetic coupling device may comprise alternating layers of magnetically permeable material and non-magnetically permeable material. The magnetic coupling device may have an adhesive backing layer and may be provided in a kit for a user to apply to a device. The embedded coupling device may be configured within the shell of a host device, or within a cover of a device.

1. A system comprising:
a host device; a magnetic coupling device including:
a first adhesive layer coupled to the host device;a first layer of magnetically permeable material attached to the first adhesive layer;a second adhesive layer atop the first layer of magnetically permeable material; anda layer of non-electrically conductive material atop the second adhesive layer; and a releasable module including a base and a plurality of magnets coupled to the base, wherein the plurality of magnets couple the releasable module to the magnetic coupling device via magnetic attraction between the plurality of magnets and the first layer of magnetically permeable material.
