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 19):
A method for wirelessly transmitting power to electric devices onboard a vehicle, comprising:\n installing a gimbal-mounted transmitter coil with first and second actuators for changing azimuth and elevation angles of an axis of the transmitter coil at a location within magnetic coupling range of first and second electric devices onboard the vehicle, the first electric device comprising a first receiver coil having an axis and a first resonant frequency and the second electric device comprising a second receiver coil having an axis and a second resonant frequency; determining a first azimuth angle and a first elevation angle for aligning a magnetic field line of a magnetic field to be produced by the transmitter coil with the axis of the first receiver coil and determining a first amplitude for an alternating electric current to be supplied to the transmitter coil based on the location of the first receiver coil, the first amplitude being sufficient to power the first electric device; determining a second azimuth angle and a second elevation angle for aligning a magnetic field line of a magnetic field to be produced by the transmitter coil with the axis of the second receiver coil and determining a second amplitude for an alternating electric current to be supplied to the transmitter coil based on the location of the second receiver coil, the second amplitude being sufficient to power the second electric device; storing the first and second azimuth angles, the first and second elevation angles, the first and second amplitudes and 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 azimuth angle, the first elevation angle, the first amplitude and the first frequency from the look-up table in response to selecting the first electric device; controlling the first and second actuators to cause the axis of the transmitter coil to have the first azimuth angle and the first elevation angle; and supplying alternating electric current having the first amplitude and the first frequency to the transmitter coil.
