Abstract: An IP inter-working gateway in an NGN includes: a transport layer module which complies with the definition of a standard TCP/IP protocol stack, for determining a service type of an IP packet from a source IP domain, and transmitting the IP packet to a service module or to a destination IP domain; the service module, for performing processing of signalling proxy, RTCP and media conversion and/or processing of control protocol for the IP packet from the transport layer module, and transmitting the IP packet processed by the service module to the destination IP domain. The embodiments of the present invention provides a method for implementing inter-working between IP domains by the IP inter-working gateway, which implements the inter-working of IP packet between heterogeneous operating networks.

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: The present invention discloses a method of call trace on an NGN MG. According to the present invention, the 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.

Abstract: An improved optical circulator transfers light from a first optical port to a second optical port, and from the second port to a third port. The circulator has non-reciprocal polarization rotators, birefringent beam splitters and combiners, and a polarization-dependent light bending device comprising two tapered birefringent plates. The light bending device compensates for an angle between a first light beam emanating from the first port and a second light beam propagating to the third port. The existence of this angle allows the first and third fibers to be coupled to the light beams using a single lens.
