US Classification:

370410, 370401, 370338, 370426, 370352, 379 9301, 379231, 379 84

Abstract:

A communication system includes a switching network and a wireless network. The switching network includes a first gateway for receiving a communication from a caller, a second gateway for establishing an external connection through which the communication can be routed, and a command center that allows the first and second gateway to make an internal connection. The wireless network includes a visited mobile switch center and a home location register. The visited mobile switch center generates routing information, receives the communication from the external connection of the switching network, and routes the communication to a wireless network subscriber. The home location register locates the visited mobile switch center, and passes the routing information from the visited mobile switch center to the command center of the switching network. The command center causes the external connection to be established based on the routing information.

Abstract:

A heat removal device includes a shroud on a top side of a printed circuit board that contains a power connector. An air intake vent is located underneath the printed circuit board and directs air up through printed circuit board vias into the shroud. Openings are located in a power connector housings that allow air to flow over conductors in the connector and out an air outtake vent. The conductors include heat sink fins that extend out of the openings in the connector housing.

International Classification:

H05H 9/00

US Classification:

315505, 315500, 156288

Abstract:

A linear accelerator having cast dielectric composite layers integrally formed with conductor electrodes in a solventless fabrication process, with the cast dielectric composite preferably having a nanoparticle filler in an organic polymer such as a thermosetting resin. By incorporating this cast dielectric composite the dielectric constant of critical insulating layers of the transmission lines of the accelerator are increased while simultaneously maintaining high dielectric strengths for the accelerator.

International Classification:

H04W 4/00

US Classification:

370328

Abstract:

A system and method for routing calls from a communication system in a VoIP network to an external network. The communication system comprises a plurality of communicating nodes. The communication system is configured to request routing information from a register associated with the external network for routing a communication to a subscriber of the external network, receive routing information from the register, and establish an external connection from the VoIP network for routing the communication to the external network based on the routing information.

International Classification:

G02B 6/12

US Classification:

385 14

Abstract:

A photo-conductive switch package module having a photo-conductive substrate or wafer with opposing electrode-interface surfaces, and at least one light-input surface. First metallic layers are formed on the electrode-interface surfaces, and one or more optical waveguides having input and output ends are bonded to the substrate so that the output end of each waveguide is bonded to a corresponding one of the light-input surfaces of the photo-conductive substrate. This forms a waveguide-substrate interface for coupling light into the photo-conductive wafer. A dielectric material such as epoxy is then used to encapsulate the photo-conductive substrate and optical waveguide so that only the metallic layers and the input end of the optical waveguide are exposed. Second metallic layers are then formed on the first metallic layers so that the waveguide-substrate interface is positioned under the second metallic layers.
