Abstract:
Systems and methods for mitigating constraints associated with wireless power transmission in applications where the position and orientation of the desired magnetic field changes over time, for example, because the position and orientation of the receiver being powered changes over time or because different receivers having different positions and orientations are being powered at different times. In accordance with some embodiments, the system employs a plurality of wireless power transmitters in a defined space, each transmitter consisting of individual coils oriented orthogonally relative to each other. Using field interference amongst these individual coils as well as amongst the transmitters they form, one can actively control the wireless power field intensity and orientation at any given point in the defined space. This allows for methods to steer the power transmission towards a specific target at a specific angle.

Claim (Index 16):
A method for wirelessly transmitting power to electric devices onboard a vehicle, comprising:\n installing a transmitter at a location within magnetic coupling range of first and second electric devices onboard the vehicle, the transmitter comprising first, second and third transmitter coils having respective axes which are mutually orthogonal, the first electric device comprising a first receiver coil having a first resonant frequency and the second electric device comprising a second receiver coil having a second resonant frequency; determining a first set of amplitudes for alternating electric currents to be supplied to the first, second and third transmitter coils of the transmitter based on the location of the first receiver coil, the first set of amplitudes being sufficient to power the first electric device; determining a second set of amplitudes for alternating electric currents to be supplied to the first, second and third transmitter coils of the transmitter based on the location of the second receiver coil, the second set of amplitudes being sufficient to power the second electric device; storing the first and second sets of amplitudes and associated first and second frequencies that respectively match the first and second resonant frequencies in a look-up table; selecting the first electric device for activation by manipulation of a first user input device; retrieving the first set of amplitudes and the first frequency from the look-up table in response to selecting the first electric device; and supplying alternating electric currents having the first set of amplitudes and the first frequency to the first, second and third transmitter coils.
