Title: Unit dose liquid dispensing and packaging for dental application
Inventor: HORN JOHN M
IPC: A61C5/06
Filed: 1999-07-23
Abstract: A nozzle for storage and application of liquid dental material, such as primer or adhesive, to a preparation site at a patient's teeth, gums or mouth. The nozzle includes a hollow nozzle for containing the liquid dental material. The hollow nozzle can include a flocked, open tip through which the liquid dental material is dispensed. The nozzle also includes a storage block having a plurality of cavities formed therein. A plurality of hollow nozzles can be inserted into the cavities to form substantially air-tight seals between the open tips of the hollow nozzles and the exterior of the cavities. An end of the hollow nozzles opposite from the open tip and exposed above the block includes a breakable seal. Accordingly, the hollow nozzles can be stored in the block for an extended period of time. To apply the liquid dental material to a preparation site, an applicator can be attached to the end of the hollow nozzle exposed above the block. The applicator is adapted to break the breakable seal and force the liquid dental material from the interior of the hollow nozzle through the open tip and onto an application site.

Title: Coordinating persistent status information with multiple file servers
Inventor: KLEIMAN STEVEN
IPC: G06F11/14
Filed: 1999-07-28
Abstract: The invention provides a storage system, and a method for operating a storag e system, that provides for relatively rapid and reliable takeover among a plurality of independent file servers. Each file server maintains a reliable  communication path to the others. Each file server maintains its own state i n reliable memory. Each file server regularly confirms the state of the other file servers. Each file server labels messages on the redundant communicatio n paths, so as to allow other file servers to combine the redundant communication paths into a single ordered stream of messages. Each file serv er maintains its own state in its persistent memory and compares that state wit h the ordered stream of messages, so as to determine whether other file server s have progressed beyond the file server's own last known state. Each file server uses the shared resources (such as magnetic disks) themselves as part  of the redundant communication paths, so as to prevent mutual attempts at takeover of resources when each file server believes the other to have faile d. Each file server provides a status report to the others when recovering from  an error, so as to prevent the possibility of multiple file servers each repeatedly failing and attempting to seize the resources of the others.</SDO AB>
Patent CA-2358230-A1 (CA)
Title: Optimized fault notification in an overlay mesh network via network knowledge correlation
Inventor: LINDHORST-KO GWENDA
IPC: H04L69/40
Filed: 2001-10-03
Abstract: Failures within a communications network are compensated for by establishing a set of two or more communications paths across the network between a source node and a destination node. At the source node a status of each one of the set of communications paths is maintained, and the data traffic is load-balanced across those ones of the set of communications paths having an operational status. In the event of failure of a physical network resource, a failure notification message is propagated to the source node, which registers a non-operation status of each path traversing the failed resource. Load-balancing of the data traffic continues across the remaining operational paths. Traffic may be prioritized based on service level agreements and quality of service protection guarantees.
