The module may be part of a rechargeable battery pack that includes data storage, or a wireless communications module that is connected to the portable computer device. In an embodiment, the data module is incorporated into a rechargeable battery pack. Data to be sent to the wireless device is transferred via a wired connection first from the charging bay to the battery pack and then from the battery pack to the wireless device when the battery pack is attached.

Abstract: A support unit for supporting articles hung from a generally planar surface is provided that includes a support arm for placement on a top surface of a generally planar surface. The support arm contacts the top surface of the generally planar surface. A mating portion contacts a bottom surface of the general planar surface opposite the top surface of the generally planar surface contacted by the support arm. A curved portion connects the support arm to the mating portion. The curved portion provides the gripping force between the support arm and the mating portion. A hook extends downwardly from the mating portion and towards the curved portion. The hook supports articles hung therefrom.
