ABSTRACT:
The electronic apparatus includes a portable electronic device and a charger for capacitively charging the portable electronic device when the portable electronic device is temporarily placed adjacent the charger. The portable electronic device includes a device data communication unit and an associated battery, and a pair of device capacitive electrodes, defining a device conductive footprint, to receive a charging signal to charge the battery. The charger includes a base having an area larger than the device conductive footprint and able to receive the portable electronic device thereon in a plurality of different positions, and an array of charger capacitive electrodes carried by the base. A charger controller selectively drives only the charger capacitive electrodes within the device conductive footprint with a charging signal to capacitively charge the battery. A charger data communication unit communicates with the device data communication unit via the charger capacitive electrodes and device capacitive electrodes, e.g. by modulating data onto the charging signal.
