Abstract:
A single management facility in a virtualized system that facilitates the presentation of either a virtual element view or system view to a network management user depending upon the user's access rights is disclosed. The user interface presented to the user is modified based on the scope and type of access rights. The scope and type of access privileges afforded to the user of the virtualized system is found in a profile object that indicates the scope and type of user access established during the user login. The profile object is stored in an environment object that is created for each user at login. Each virtualized element in the system includes management information that is associated with the virtual element via a virtual identifier. The management information indicates the level of the user access privileges necessary to view the associated virtual element. Requests by a user to access management information associated with a virtual element are analyzed to determine if the access privileges specified in the user profile enable the user to access the virtual element and if so to perform the type of operation requested.

The view presented to the user is modified based on the scope and type of access rights, which are found in a profile object, that is stored in an environmental object, established during the user login. Each virtualized element in the system includes management information that is associated with the virtual element via a virtual identifier. The management information indicates the level of the user access rights necessary to view the associated virtual element. Requests by a user to access management information associated with a virtual element are analyzed to determine if the access rights specified in the user profile enable the user to access the information associated with the virtual element.
Abstract:
A diesel engine comprising an exhaust system comprises: a particulate filter made from a porous material having a mean pore diameter of from 5 μm to 40 μm, and a porosity of at least 40% and a bulk volumetric heat capacity of at least 0.50 J cm−3 K−1 at 500° C., which filter comprising a diesel oxidation catalyst located in a zone on the front end of the filter for oxidising carbon monoxide, hydrocarbons and nitrogen monoxide, the engine comprising engine management means, in use, to provide continuously or intermittently an exhaust gas comprising sufficient nitrogen oxides or hydrocarbon and/or an exhaust gas of sufficiently high temperature to combust particulate matter in the filter.
Abstract:
An applicator and material dispensing system having an applicator frictionally retained within an applicator holder and the applicator holder frangibly attached to a material holder. Material placed within the material holder is initially sealed by a frangible portion adjacent one end of the applicator holder. Upon separation of the applicator holder from the material holder the material contained therein is exposed permitting the applicator, upon removal from the applicator holder, to be used to dispense the material. The invention is particularly well suited to dispensing small quantities of dental material.
Abstract:
In one general aspect, a network communication unit is disclosed that includes connection servicing logic that is responsive to transport-layer headers and is operative to service virtual, error-free network connections. A programmable parser is responsive to the connection servicing logic and is operative to parse application-level information received by the connection servicing logic for at least a first of the connections. Also included is application processing logic that is responsive to the parser and operative to operate on information received through at least the first of the connections based on parsing results from the parser.
Abstract:
An above-ground tank auto-limiter is provided for preventing the overflow of fluid in storage tanks. The auto-limiter includes a valve assembly insertible downward through the top of a fill pipe of the fuel storage tank. The valve assembly has a cylindrical valve housing providing a fluid flow passage directing fuel downward into the storage tank under pressure. A hollow cylindrical float is provided in the valve assembly and is coaxially mounted along the outside surface of the valve housing leading into the storage tank. The float moves vertically to slide freely along the lower portion of the valve housing with the fluctuation of the fuel level within the tank. A series of linkage assemblies communicate the cylindrical float to valve doors. The valve doors prevent any fluid flow from passing through the fluid flow passageway when the doors are in the closed position. Bleed valves disposed in the valve assembly above the valve doors function independently from the linkage assemblies and valve doors to allow a certain amount of excess fuel that is captured within the valve housing when the fluid flow passageway is closed to bleed into the storage tank when pressure in the valve assembly is released.
