  • Patent number: 7504802
    Abstract: An 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 housing, a battery carried by the housing, and at least one pair of device capacitive electrodes carried by the housing for charging the battery and defining a device conductive footprint. The charger includes a base having an area larger than the device conductive footprint, and an array of charger capacitive electrodes carried by the base. The charger further includes a charger controller for selectively driving the charger capacitive electrodes within the device conductive footprint with a charging signal sufficient to capacitively charge the battery of the portable electronic device and not driving charger capacitive electrodes outside the device conductive footprint.

  • Patent number: 7330216
    Abstract: An improved handheld electronic device includes an improved battery compartment door having a miniature camera disposed thereon. The battery compartment door with its camera advantageously does not alter the form factor of the handheld electronic device and can easily be replaced with a similar battery door without a camera which, when installed on the handheld electronic device, will provide the same form factor. A battery compartment of the handheld electronic device is configured to be larger than required to accommodate a battery of the handheld electronic device in order to also accommodate the camera of the battery compartment door.
