Abstract
In the field of wireless power, to enable interoperability between chargers and receivers, it is important that the two parts of the system (the charger and receiver) can communicate in a manner that allows operation. With the proliferation of different communication schemes, a multi-protocol system that can adapt and interoperate with different communication protocols allows maximum interoperability. Described herein are systems and methods for providing such multi-protocol operation and maximum interoperability. Also described herein are methods for use of magnets in or around magnetically sensitive devices such that the operation of such a device is not impaired. Applications in various devices and systems are described. In particular, applications for fastening mobile devices to their cases or other surfaces, and also alignment or attachment for power transfer or charging are described.
