Abstract:
1. A charging unit to be used by an electronic device to charge an electronic device, the charging unit comprising: a first outer surface comprising a charging surface; a second outer surface and comprising a display surface, wherein the second outer surface is opposite the first outer surface such that when the charging surface is oriented upwards to receive an electronic device thereon for charging, the display surface is oriented downwards and is non-viewable; an initialization component configured to enable a load detection component based upon detecting that the charging surface is oriented upwards, the initialization component including an orientation tracking component configured to determine whether the charging device is oriented upwards such that the at least one charging surface thereon is engageable by the electronic device, wherein the load detection component is not enabled when the orientation tracking component determines that the charging device is not oriented upwards such that the at least one charging surface thereon is engageable by the electronic device, wherein the charging unit is not capable of detecting the electronic device when the load detection component is not enabled; the load detection component configured to detect engagement of the electronic device at the charging surface when enabled by the initialization component; and a charging component that is configured to wirelessly provide power to an engaged device at the charging surface via electromagnetic induction when the load detection component detects the engaged device; wherein the display surface is configured to display graphical information based on a determination by the orientation tracking component that the charging device is oriented to allow viewing of the display surface.
