Embodiment Construction

[0046] In the following description, for purposes of explanation, several examples and specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it is obvious to those skilled in the art that the present disclosure as expressed in the claims may include some or all of the features in these examples alone or in combination with other features described below, and may further include here Modifications and equivalents of the features and concepts described.

[0047] Wireless power transfer may involve transferring any form of energy associated with electric, magnetic, electromagnetic, or otherwise, from a transmitter to a receiver without the use of physical electrical conductors (eg, power may be transferred through free space). Power input into a wireless field (such as a magnetic or electromagnetic field) can be received, captured or coupled by a "power receiving element" for power transfer.

[0048] figure 1 is a funct...
