20130332077 | Encoded Representation of Route Data - For a route server that generates route data for a route between a starting location and a destination location on a map, a method of compressing the route data that includes a maneuvering instruction for each of a plurality of junctures from the starting location to the destination location of the route is described. For a maneuvering instruction for each juncture of the route, the method determines whether the maneuvering instruction for the juncture is needed at a route client that is to receive the route data. When the maneuvering instruction for a particular juncture is determined not to be needed at the route client, the method modifies the route data by removing the maneuvering instruction for the particular juncture from the route data. | 12-12-2013 |

20100089686 | MAGNETIC APPARATUS AND METHOD OF MANUFACTURING THE MAGNETIC APPARATUS - The present invention provides for a magnetic apparatus and a method of manufacturing the magnetic apparatus including a magnet having an outer surface and an inner surface opposing each other with the inner surface having a first portion and a second portion integrally connected to and facing each other and utilizing a fluid and a fixture body defining a hole along a fixture axis and a deflector disposed within the hole. The method includes the steps of installing the magnet on the fixture body and securing the magnet to the fixture body. The method further includes the steps of flowing the fluid through the magnet transverse to the fixture axis to form at least one aperture and intersecting the fluid with the deflector to redirect the fluid generally along the fixture axis. | 04-15-2010 |

20080247382 | System and method for providing improved VoIP services - The invention provides a system and method for providing voice over Internet protocol (“VoIP”) services with an improved quality of service (“QoS”). In one embodiment, a number of gateways or proxies are connected with dedicated links to form a dedicated network. Each gateway is also on one or multiple communication networks, such as individual communication networks provided by different network providers. Each user of the system uses an ATA to connect to the dedicated network, which then connects the user to another ATA of another user, thereby establishing a connection between these two users. The connection between each of the ATAs and the dedicated network is made through communication network or networks. As the quality of a public network is generally not managed by a VoIP service provider, it is desirable to minimize the effects of public network or networks. A method is provided for selecting a gateway that provides the best connection possible to the dedicated network. The selection may be based, for example, network latency. The selected gateway then selects the best receiver gateway for routing the connection request and to connect to the receiver's ATA. | 10-09-2008 |

20120127854 | METHOD OF SHRINKING A DATA LOSS WINDOW IN A PACKET NETWORK DEVICE - A packet network device includes a control module, one or more line cards each one or which includes a plurality of ingress and egress ports, and each of the ingress and egress ports are connected to external network links. The line cards maintain forwarding tables and include functionality that employs information in the forwarding tables to determine how incoming packets of information should be forwarded. The control module includes functionality that operates to learn reachability information about other devices connected to the network that are and to use this reachability information to update forwarding tables maintained on the line cards. The control module also includes an enhance ARP functionality that operates in cooperation with standard ARP functionality and other network protocols included on the control module to diminish the amount of data lost in the event that a link connected to one of the egress ports fails. | 05-24-2012 |

20100226260 | SPANNING TREE RING PROTOCOL - A plurality of network devices such as routers are included in an instance of a spanning tree. The network device creates a ring context on a port that it identifies as both a blocking port and configured to run a spanning tree protocol. The ring context can be comprised of a region name, an STP domain name or a spanning tree instance. The network device transmits a ring discover message for the ring context over a forwarding port and determines that a ring exists when it receives the message at a blocking port. The network device subsequently transmits a reverse ring discover message from its blocking port which includes the status of the discovered ring to the members of the ring topology. | 09-09-2010 |
