Abstract
A wireless power charger (WPC) integrated into a charging pad (CP) includes a wireless power transmitter (WPT), a location sense mechanism (LSM), a transport mechanism (TM) and a Central Control Unit (CCU). The LSM discovers and conveys the position of a portable device to the CCU when the device is placed on the CP to have its battery wirelessly charged. The LSM uses RF signaling and other capabilities in wireless connectivity standards to detect location of device. With information from the LSM, the CCU, via the TM, moves the WPTM in close proximity to the device. Once at the device position, the WPTM senses the location of the receiver coil in the device, adjusts its position via the TM to gain strong alignment and provides power wirelessly. When charging is complete or if the device is removed from the charging pad, the WPTM returns to its home-base location.
