Abstract: A virtual management system for a network facility, such as a data center, or any facility having a plurality of components which can be organized as objects for presentation in a virtualized environment, is disclosed. The system includes a management topology presenting devices, facilities, subscribers, log servers, and services as objects to an administrative interface; and a configuration manager implementing changes to objects in the topology responsive to configuration input from an administrator via the administrative interface. In an exemplary embodiment, the user interface is a graphical user interface designed to work in a platform independent environment. The system may include a management server coupled to the plurality of objects. In one aspect, the management server communicates with the devices, downloading configuration data to and uploading configuration data from, the devices. The management server and the interface may communicate via a LAN, WAN or the Internet.

Abstract: A pump for producing a substantially smooth and continuous outflow of liquid at relatively high pressure has two piston assemblies flow connected in series. The first piston assembly includes a pressure piston having a long suction stroke and a relatively short and abrupt expulsion stroke. A valve at the inlet of the pressurization piston allows flow to enter (but not exit), and a valve at the outlet of the pressurization piston allows flow to exit (but not enter). The second piston assembly includes a damper piston which functions as a mechanically driven damper to smooth the outflow from the pressure piston. This smoothing is accomplished by storing of the liquid displaced by the expulsion stroke of the pressure piston and then delivering the stored pressurized liquid to the pump outlet during the suction stroke of the pressure piston.
