SYSTEMS AND METHODS FOR WIRELESS POWER TRANSFER
First Claim
1. A system for contextually-aware wireless power transfer, comprising:
- a base unit having one or more transmitter coils;
one or more components including a ferromagnetic, ferrite, or other magnetic material or layers, that modify the magnitude and/or phase of an electromagnetic field and/or corresponding magnetic flux in one or multiple dimensions and/or to guide the magnetic flux in such a manner as to create a preferential path for flux flow in one or multiple dimensions; and
wherein, when vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries having one or more receiver coils or receivers associated with, are placed in proximity to the base unit, the transmitter coil is used to inductively generate a current in the receiver coils or receivers associated with the vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries, to charge or power the vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries, and at the same time the system perform one or more context-aware action.

Abstract
Systems and methods for enabling efficient wireless power transfer, and charging of devices and batteries, in a manner that allows freedom of placement of the devices or batteries in one or multiple (e.g., one, two or three) dimensions. In accordance with various embodiments, applications include inductive or magnetic charging and power, and wireless powering or charging of, e.g., mobile, electronic, electric, lighting, batteries, power tools, kitchen, military, medical or dental, industrial applications, vehicles, trains, or other devices or products. In accordance with various embodiments, the systems and methods can also be generally applied, e.g., to power supplies or other power sources or charging systems, such as systems for transfer of wireless power to a mobile, electronic or electric device, vehicle, or other product.

11. A method of providing contextually-aware wireless power transfer, comprising:
-
providing a base unit having one or more transmitter coils; providing one or more components including a ferromagnetic, ferrite, or other magnetic material or layers, that modify the magnitude and/or phase of an electromagnetic field and/or corresponding magnetic flux in one or multiple dimensions and/or to guide the magnetic flux in such a manner as to create a preferential path for flux flow in one or multiple dimensions; and wherein, when vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries having one or more receiver coils or receivers associated with, are placed in proximity to the base unit, the transmitter coil is used to inductively generate currents in the receiver coils or receivers associated with the vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries, to charge or power the vehicles, mobile devices, cases, skins, battery doors, dongles, or batteries, and at the same time performing one or more context-aware actions.
