Abstract
A method is provided that includes identifying, by a power transferring unit, a power receiving unit in a proximity of the power transferring unit. The method further includes determining whether the power receiving unit is in a near field range or in a far range of the power transferring unit, receiving a power status from the power receiving unit and generating, in the power transferring unit and based on the power status information, a directed energy signal from a power transferring unit to the power receiving unit when the power receiving unit is within a far range of the power transmitting unit. The method includes generating, in the power transferring unit and based on the power status, an inductively coupled field that is resonant with the power receiving unit, when the power receiving unit is within at least a near field range of the power transferring unit.
