Abstract: Methods, systems, and associated components for the enhanced categorization, accessing and display of information stored in a computer database. The invention provides databases that comprise information components or content that is annotated with descriptive reference components or tags in order to provide a semantic reference to the content. Use of semantic categorization provides databases and the information contained within them to have greater dimensionality and richness which translates to richer queries and query results.

Abstract: The present invention provides an underground tank having a vessel assembly and a generally spaced access assembly. That is, the access assembly includes a fuel line, a withdrawal line, and a dome assembly. The fuel line and the withdrawal line have a first end disposed outside the vessel assembly and a second end disposed adjacent to or within the vessel assembly. The first end extends upwardly from the vessel assembly toward the ground surface. The dome assembly is coupled adjacent to the fuel line and withdrawal line first end. As such, the vessel assembly may be buried at any depth as the fuel lines and withdrawal lines may have any length.

Abstract: An electronically controlled fuel injector includes a reduced part count and complexity over similar fuel injectors without a substantial reduction in performance capabilities. This is accomplished by using a one-piece needle that is hydraulically balanced and biased toward a closed position with a spring positioned in the needle control chamber. Although subtle, this injector has some ability to control the fuel pressure when the needle valve is opening and closing by adjusting a relative timing of a pressure control valve opening relative to a needle control chamber, using separate electrical actuators. The invention is particularly applicable to fuel injectors that cycle through high and low pressure states during and between injection events, respectively. Cam actuated fuel injectors being particularly well suited.
