  • Patent number: 9085086
    Abstract: An electric apparatus comprises a housing (2) and a trimmer (3) for cutting hair. The trimmer (3) is carried by a trimmer supporting element (5) which is movable between a stored position and an operational position. In the operational position the trimmer (3) is spaced from the housing (2). The trimmer supporting element (5) is rotatably connected to the housing (2) through a supporting element hinge (8), which is movable with respect to the housing (2) via a guide (9) in a direction perpendicular to the axis of rotation of the supporting element hinge (8). The apparatus further comprises a displacement member (11) for defining the displacement of the trimmer supporting element (5) between the stored position and the operational position.

  • Publication number: 20070110076
    Abstract: A message interworking gateway (1) resides in an overlay IMS network (2) associated with a home SS7 network (10). The gateway (1) intercepts requests for routing information (MAP-SRIs) from either the home SMSC (11) or a foreign SMSC. If the message recipient is available on the IMS overlay network (2) the gateway (1) performs protocol translation AND routes the translated message to the recipient. If not, the gateway returns the SRI to the home (10) network. The gateway operates without updating the home HLR (12) with user presence data and hence voice traffic can be kept on circuit switched technology without being routed to the IMS overlay network (2).
