Abstract: A mobile packet gateway obtains a network address of the terminal and a network address of a gateway virtual interface. The network address of the gateway virtual interface and the network address of the terminal belong to a same network segment. A virtual interface is created for a Packet Data Protocol Context (PDP context) of the MS according to the network address of the gateway virtual interface. A network segment address of a branch network served by the MS is obtained from the MS through the virtual interface according to a dynamic routing protocol.

Abstract: An exemplary fastener feeder includes a pair of guiders, a slot cover and a blocker. The guiders define a sliding slot therebetween. Each guider includes a sloped part and a level part, bodies of the fasteners are capable of being received in the sliding slot, and a head of each fastener is capable of sliding down from the sloped parts and stopping on the level parts. The slot cover defines an opening for providing a path through which a fastener pickup device can pass through and engage with a fastener located on the level parts. The blocker is located below the level parts. When the fastener pickup device moves the fastener head engaged therewith away from the opening and a length of the fastener is greater than a distance between the blocker and the level parts, the fastener is blocked by blocker and disengaged from the fastener pickup device.

Abstract: Message handshaking and integration may be provided. A message may be created by a client in a first format. The client may determine whether a server in communication with the client is operable to deliver the message in a second format. If so, the client may provide the message, in the first format, to the server for delivering to at least one recipient in the second format.

Abstract: The present invention discloses a method of call trace on a next generation network (NGN) media gateway (MG). According to the present invention, a softswitch device adds an extended trace indication to an H.248 message related to the call to be traced; the MG determines whether the received H.248 message needs to be traced according to the extended trace indication; and if the H.248 message needs to be traced, trace the call to which the transaction in the H.248 message belongs. By the method, the MG can trace the entire calling process of a call.

Abstract: Described are various optical devices having at least two optical waveguides for inputting and outputting optical beams coupled thereto by a single collimating lens. Located proximate to the lens is a polarization dependent beam directing device that deflects orthogonally polarized optical beams in opposite directions by a first and second angle, respectively, when the beams are propagating in the same direction. The polarization dependent beam director compensates for an angle between a first beam input via a first of the two waveguides and a second beam input via a second of the two waveguides. The polarization dependent beam director also deflects a first beam propagating towards the waveguides in a first direction so that it is output via the first of the two waveguides and deflects a second beam propagating towards the waveguides in a second direction opposite the first so that it is output via the second of the two waveguides. Disclosed are three and four port interleavers and a four port circulator.
