  • Patent number: 6885661
    Abstract: The present invention guarantees that voice data (and other information types) will switch within a predetermined time period. Systems and methods consistent with the present invention accomplish this guarantee by, among other things, establishing permanent virtual paths between each network element, guaranteeing each voice line a slot in a packet in each frame, employing both octet switching and packet switching, synchronizing the operation of the network elements to a reference clock, and providing several levels of network redundancy.
    Type: Grant

  • Patent number: 6785840
    Abstract: A system for implementing a high-availability architecture comprising a first compact Peripheral Component Interconnect shelf, a second compact Peripheral Component Interconnect shelf, and a network. The first and second compact peripheral component interconnect shelf are redundant systems. The first compact peripheral component interconnect shelf comprises a first system utility card connected to a first compact core to network interface connected to a first compute platform connected to a first high speed pipe interface. The second compact peripheral component interconnect shelf comprises a second system utility card connected to a second compact core to network interface connected to a second compute platform connected to a second high speed pipe interface. The first and second compact peripheral component interconnect shelf are connected via Ethernet. The first and second compact core to network interface is connected to the network.

  • Publication number: 20020173300
    Abstract: A method and system for context-based data completion is described. In one embodiment, information is inputted by a user into a wireless device (or the like), and based on specific addressing data of information provided by the user, additional data is appended to some of the data entered into the wireless device in order to facilitate communication to a separate device.

  • Patent number: 4576517
    Abstract: A marine heave compensating device comprises a hydraulic piston and cylinder unit (15,16) with its cylinder (15) secured to a support (10,11). The piston is connected via a piston rod (16) to a cross-head (17) on which a first set of pulleys (18) are rotatably mounted. Chains (19) secured at one end to the support (10,11) are entrained around pulleys (18) and support a yoke (20) on which is mounted a crown block (21). A cable (22) is reeved around crown block (21) and around a travelling block (23) which carries a tool carrier (24). The two ends of cable (22) are reeved around two second pulleys (26A,26B) rotatably mounted on the cross-head (17). End (22A) of cable (22) is connected to a draw-works and end (22B) of cable (22) is connected to a tie-down.
