  • Patent number: 6161134
    Abstract: The invention provides an information appliance and a network appliance (or telephone) that function independently as well as with each other as companion appliances. The information appliance stores user information corresponding to a particular user. The telephone is linked to network. In some embodiments, the companion appliances are capable of simultaneously exchanging voice and data messages with devices connected to the network. The appliances are connected to each other physically through a communications port, and exchange data link layer formatted data corresponding to user personalized information, commands from the user, and responses including message status information corresponding to action of the network connected devices. The user information enables the telephone to perform network communications according to user specified settings, and enables the telephone to assume the user specific information appliance network identification.

  • Patent number: 6149786
    Abstract: A modified universal exhaust gas oxygen sensor, referred to herein as a CEGA sensor, is provided which can be used to measure the concentration of a variety of components of a gaseous fuel emission including CO, CO.sub.2, O.sub.2, H.sub.2, and H.sub.2 O. The CEGA sensor employs at least one additional electrode on a ceramic substrate which possess a different catalytic activity relative to the electrodes that normally found on a UEGO sensor. The ceramic substrate may be made of any suitable ceramic and is preferably made of zirconia. The difference in catalytic activity between the additional electrode(s) and the electrodes native to the UEGO sensor create an oxygen gradient which enables a measure of combustion completeness to be calculated. In combination with an air/fuel ratio measured by the sensor, the concentrations of different components in the emission can be calculated.

  • Patent number: 6151213
    Abstract: A platform for holding a plurality of modules or printed circuit boards wherein the platform or chassis contains shutters placed over airflow openings in the platform. The shutters are normally closed and are opened by the act of inserting a module into the platform. The shutters are in the closed position in all slots not occupied by a module and are in the open state in all slots populated by a module. The shutters open as the module is inserted and close when the module is removed. The closed shutters prevent airflow from passing through the unpopulated slots and empty space within the platform, thus forcing the airflow to pass through the space in which the modules are present. The platform also comprises a means of controlling the number of fans that are operational in accordance with the number of modules installed in the platform. The fans closest to the modules inserted into the platform are operational while fans close to unpopulated slots are turned off.

  • Patent number: 6147987
    Abstract: The present invention provides a modular architecture for connecting a plurality of telephone lines to a computer network. The invention binds a plurality of network access servers together so that they form a single system image to clients dialing into the plurality of network access servers. The invention operates by providing a tunneling mechanism for communication between the network access servers. The tunneling mechanism facilitates packet re-forwarding so that a call dialed into a physical port in a network access server can be re-forwarded through a logical port in another network access server. This allows a call to be routed through a physical port in a network access server even if no logical port is available in the network access server. Packet re-forwarding also allows multilink connections through physical ports in multiple network access servers to be routed through a single logical port in a network access server.

  • Patent number: 6147971
    Abstract: Two solutions are provided for optimizing the algorithm used by the local node in calculating the route to a destination node. A first method optimizes the route calculation by associating a port/link information with the PTSEs received by the node. The association is made using the first PTSE to arrive from an originating node. The routing algorithm is then steered to begin routing to a destination using the associated port/link. A second method optimizes the route calculation by utilizing a special PTSE termed a ROUTE.sub.-- PTSE into which is placed the route the PTSE takes upon being flooded from the creating node to the local node. When routing, the local node traverses the DTL already existing in the ROUTE.sub.-- PTSE received from a particular originating node that is the current destination node.

  • Patent number: 6141126
    Abstract: An optical switch utilizing WDM or DWDM techniques for use in both WAN and LAN environments. Each input to the switch is assigned a separate wavelength via a tunable transmitter. The output of the transmitters are input to a star coupler which combines all the optical signals into a single optical output signal. This signal is input to an optical demultiplexor which functions to split the incoming optical signal into a plurality of separate wavelengths with each wavelength steered to a particular output port. The output of each port, corresponding to a particular wavelength, is then converted into an electrical signal by a receiver. Unicast, broadcast and multicast calls are supported. A plurality of unicast connections can be established simultaneously by assigning each tunable transmitter a different wavelength such that all wavelengths are mutually exclusive with each other.

  • Patent number: 6122549
    Abstract: An externally guidable intervertebral disc apparatus manipulates disc tissue at a selected location of an intervertebral disc. The apparatus comprises a catheter having a distal end, a proximal end and a longitudinal axis. The catheter has an intradiscal section at its distal end. The intradiscal section is extendible into the disc, has sufficient rigidity to be advanceable through the nucleus pulposus and around the annulus fibrosus of the disc under a force applied longitudinally to the proximal end, has sufficient flexibility in a direction of the disc plane to be compliant with the inner wall, and has insufficient penetration ability to be advanceable out through the annulus fibrosus under the applied force. A thermal energy delivery device is located in the intradiscal section for preferentially heating the selected location of the disc. The apparatus is used to locally and controllably heat but not char or burn tissue in a disc. Such heat shrinks the collagen component.
