Method and apparatus for displaying a view of an application on a touch-sensitive display include detecting a touch on the touch-sensitive display. In some embodiments, two or three dimensional projections spatially represent relationships between search parameters, located along the periphery of the projections and search hits whose significance are represented by position relative to the center of the projection and comparative distance from each of the search parameters. The electrical control system provides power from an inboard side of the wheel frame to an outboard side via a slip ring assembly having connector assemblies passing through the wheel frame for controlling motion of the wheel cover. Simulation of fluid flow in production equipment is initiated using the surface facility network simulator. A backlight unit according to an embodiment of the present invention includes: a plurality of lamps; a common electrode electrically connected to an electrode of any one of the lamps; and a lower side support that supports the common electrode and that includes a shielding part, wherein the shielding part is in between a portion of the common electrode and the electrode. At least one of the circuit components can be tested independently of the other circuit components.
