1. A method for automatic wireless charging alignment comprising:
- calculating a wireless power transfer efficiency during a wireless charging session involving a wireless charging assembly having a transmitting coil and an electronic device having a receiving coil mounted to a linear actuator mechanism;
controlling the linear actuator mechanism to move the receiving coil in a lateral direction such that the wireless power transfer efficiency increases;
determining whether to move the receiving coil in a first lateral direction or a second lateral direction opposite the first lateral direction; and
controlling the linear actuator mechanism to move the receiving coil in a lateral direction determined in the determining.

14. A linear actuator mechanism comprising:
-
an x-direction movement means configured to move a receiving coil platform laterally in an x-direction; a y-direction movement means configured to move the receiving coil platform laterally in a y-direction; and one or more motors configured to actuate the x-direction movement means and the y-direction movement means, wherein a receiving coil is mounted on the receiving coil platform, such that actuation of the x-direction movement means causes a lateral movement of the receiving coil in the x-direction, and actuation of the y-direction movement means causes a lateral movement of the receiving coil in the y-direction. - View Dependent Claims (15, 16, 17, 18, 19)
