Appl. No.:

12/643378

Inventors:

Thomas Linden - Los Gatos CA, US
James Huang - Irvine CA, US
Jeff Hsu - San Jose CA, US

Assignee:

Watchguard Technologies, Inc. - Seattle WA

International Classification:

G06F 15/177

US Classification:

709220

Abstract:

A computing device may be joined to a cluster by discovering the device, determining whether the device is eligible to join the cluster, configuring the device, and assigning the device a cluster role. A device may be assigned to act as a cluster master, backup master, active device, standby device, or another role. The cluster master may be configured to assign tasks, such as network flow processing to the cluster devices. The cluster master and backup master may maintain global, run-time synchronization data pertaining to each of the network flows, shared resources, cluster configuration, and the like. The devices within the cluster may monitor one another. Monitoring may include transmitting status messages comprising indicators of device health to the other devices in the cluster. In the event a device satisfies failover conditions, a failover operation to replace the device with another standby device, may be performed.

Appl. No.:

8/747433

Inventors:

James Huang - San Jose CA

Assignee:

InnoMedia Pte, Ltd.

International Classification:

H04Q 1104

US Classification:

370420

Abstract:

A terminal adapter for ISDN services is implemented using a digital signal processor rather that a general purpose microprocessor, and provides normal terminal adapter functionally while at the same time substantially reducing part count and increasing flexibility and reliability. The terminal adapter uses a pipelined operating system involving a series of hierarchical menus of subtasks to perform the various functions required for ISDN operability.

International Classification:

US Classification:

Abstract:

An improved osmotic engine is disclosed. The osmotic engine is adapted to be used with an osmotically driven syringe which can be used to deliver a beneficial agent, such as a drug, at a pre-determined rate over an extended period of time. The osmotic engine has an exterior wall defining a compartment which contains an osmotic solute. The wall comprises a thin permeable and/or microporous material which is permeable to an external fluid such as water but is impermeable to the solute. The wall also has a delivery orifice drilled therethrough. A rigid non-dissolving ring-shaped wall support is provided for maintaining the shape of the engine during use. The wall support also provides an open fluid flow path extending from the semipermeable wall portion toward the delivery orifice. The open fluid flow path minimizes the time required for the engine to begin pumping.
