  • Patent number: 11648692
    Abstract: A personal care product system having a personal care product stand and a handle is provided. The handle can be docked with the personal care product stand when not in use. The position of the handle relative to the personal care product stand is maintained by a docking magnet in the handle and a docking magnet in the personal care product stand. The handle is tilted with respect to a vertical axis and a majority of the handle is unsupported.
    Type: Grant

  • Patent number: 11648693
    Abstract: A personal care product system having a stand and a handle is provided. The handle can be docked with the stand when not in use. The position of the handle relative to the stand is maintained by a docking magnet in the handle and a docking magnet in the stand. The stand includes a base having a stand resting plane and an opposing top surface. The handle extends upward from the opposing top surface of the stand and is tilted with respect to a vertical axis with a majority of the handle being unsupported. A handle resting plane intersects the stand resting plane at an included angle of less than 90 degrees, and an axis of polarity of the docking magnet in the handle intersects the handle resting plane at an included angle between 15 and 35 degrees to facilitate the tilted position of the handle.

  • Patent number: 7927753
    Abstract: The invention relates to a method for operating a direct oxidation fuel cell in which at least one fluid fuel is transported from a fuel reservoir via a fluid distribution structure to a membrane electrode assembly, the transport of the fuel being effected passively, i.e. without convection. Furthermore, the invention relates to a corresponding direct oxidation fuel cell.

  • Patent number: 7887621
    Abstract: The invention relates to a device which comprises a channel (1) carrying a flowable medium. The due operation and/or maintenance of the device is associated with the formation of inclusions (3) inside the channel (1) of a fluid or gas distinct from the aforementioned medium. The channel (1) is configured in such a manner that the inclusions are moved towards a channel exit (4) by capillary forces. The invention also relates to a method for removing inclusions (3) from corresponding devices.
