Signaling gateway for multihop-relaying a signaling message
If interaction between signaling gateways frequently occurs, it is possible that extended processings are executed redundantly on a path of signaling messages. To avoid such a redundancy, a consistent method is necessary for deciding a signaling gateway to execute an extended processing from among the signaling gateways. The signaling gateways, each time they receive a signaling message, calculate information about a path through which it is transferred. By passing the path information in addition to the signaling message to an extended processing program, the signaling gateways decide whether to execute the extended processing on the signaling gateways, on a session basis. A signaling gateway that has executed an extended processing adds information indicating a processing status to the signaling message to notify other signaling gateways of it. |

Method and system for supporting internet protocol mobility of a mobile node in a mobile communication system
A method and system for supporting Internet Protocol (IP) mobility of a Mobile Node (MN) in a mobile communication system.

Method and apparatus for automatic inter-domain routing of calls
A method and apparatus for inter-domain routing of calls in a network, where the network represents a first wide area network. A routing node of the network advertises its access to a range of addresses in a second wide area network and a cost for access to the range of addresses to all adjacent nodes in the network. Each of the adjacent nodes inserts an entry in its own routing table associating access to the range of addresses in the second wide area network with the network address of the routing node and the cost for access. Each adjacent node then modifies the cost for access by adding its own cost and advertises its access to the range of addresses in the second wide area network and the modified cost for access to all of its adjacent nodes. When a call addressed to a destination address in the range of address in the second wide area network is received at each node of the network, then the node searches for the entry in its routing table corresponding to the range of addresses in the second wide area network having the lowest cost for access and connects the call to the adjacent node associated with the entry having the lowest cost. The routing node can also advertise one or more protocol types which it can support, where the protocol types are associated with the routing node in the routing table in each adjacent node and a call having a given protocol type is also routed at each node of the network based upon its protocol type. |

Producing time variation in emanating light
An excitation component or arrangement can provide excitation to a moving object so that information is encoded in time variation of light emanating from the object. For example, in each of a sequence of segments, it can provide a respective non-binary excitation spectrum, and the spectra can be different with a non-interference-like transition between them; because the object emanates light differently in response to the different spectra, photosensing results can be obtained that include encoded information about the object. The non-binary spectra could be different intermediate intensities, such as different gray levels or different intensities of one color or could be different colors. The excitation can be provided in a pattern with non-interference-like transitions between regions, and object motion can also be controlled. In another approach, a trigger signal can cause a time-varying excitation in a region, with non-interference-like transitions between intervals of excitation, such as black/white, multiple colors, or gray levels. |

RLSA CVD deposition control using halogen gas for hydrogen scavenging
Film thickness uniformity and stoichiometry are controlled and deposition rate is increased in the chemical vapor deposition (CVD) of silicon nitride from complex gas mixtures in microwave plasmas. In Si2H6+NH3+Ar gas mixtures using a radial line slot antenna (RLSA) microwave plasma to deposit SiN by CVD, deposition rate and film uniformity are improved by limiting the amounts of atomic or molecular hydrogen from the gas mixture during the deposition process.

The halogen scavenges hydrogen from the mixture, and prevents the hydrogen from blocking the nitrogen and silicon atoms and their fragments from bonding to the surface atoms and to grow stoichiometric silicon nitride. Adding the halogen generates free halogen radicals that react with hydrogen to create hydrogen halide, for example, HF or HCl, thereby scavenging the hydrogen. |
