Abstract: A valve assembly includes an assembly housing and fluid valves disposed in the assembly housing. The assembly housing includes a first manifold that defines a plurality of first ports and a second manifold that defines a plurality of second valve ports. Each second valve port is associated with a corresponding one of the first ports to form a port pair. The assembly housing includes a valve chamber disposed between the first manifold and the second manifold. The valve chamber is in fluid communication with an interior space of the first manifold via the first ports and is in fluid communication with an interior space of the second manifold via the second valve ports. Each fluid valve is configured to control fluid flow between the first valve port and the second valve port of a respective port pair.

Abstract: A cam-driven valve system includes a valve housing configured to define a plurality of fluid passageways and to support an array of sliding gate fluid valves in the fluid passageways in such a way that the flow of fluid therethrough is controlled. The system includes a plurality of cams supported on a cam shaft. The cam shaft is arranged so that each cam is associated with a corresponding sliding gate valve. Rotation of the cam shaft results in actuation of the valves via the cams. The cams of the cam shaft vary in shape and size.

Abstract: Example implementations relate to management of network topologies. A primary tree having multiple connection graphs is generated for each node in the network. Each connection graph has at least one ordered list of one or more network node connections and the generated connection graphs provide a full network fit for each node in the network. The connection graphs are stored in at least one network switch to be used for network switch functionality. Additional connection graphs are generated for one or more network nodes connections based at least on network link capacity and provide for sharing of one or more of network links between multiple network node connections. The additional connection graphs are stored in the at least one network switch to be used for subsequent network switch functionality.

Abstract: A method, system and computer program product for a generic data storage interface for local and remote networked storage is provided. It comprises providing a data storage interface accessible by an operating system, transmitting data from an application running on the operating system to the data storage interface and selectively storing the data using the same data storage interface in either a local or a remote networked storage location. Firmware for the common data storage interface assigns a unique identifier that classifies an I/O request as a local or remote networked I/O request and adds the I/O request to a common stack for local and remote networked data storage elements. When an I/O request is removed from the stack, the unique identifier is used to identify the I/O request as a local or remote networked I/O request. Local I/O requests are executed via a local bus such as PCI, or SCSI.
