Abstract: Systems and methods for controlling a display system. The methods comprise: detecting an occurrence of an event; initiating a display session based on the event being of an event type to trigger a display session; and selecting media content (MC) for display by computing devices (ICDs) (wherein ICDs are located in areas or sections (SA/S) of a venue); selecting a first SA/S at which display of MC is to begin; identifying first CDs (FCDs) that are located in the first SA/S; causing FCDs to notify users that FCDs are to be moved into positions in which first pixel panels are visible by persons located outside of the first SA/S; and causing each FCD to display a respective pixel portion of a first electronic graphic (FEI) contained in MC, whereby an entirety of FEI is displayed collectively by FCDs.

Abstract: A combustion engine component comprises an assembly of a belt pulley for driving auxiliary engine equipment and a torsional vibration damper. The assembly is adapted to be fixed on an engine crankshaft, wherein the belt pulley is of a so called decoupling type, arranged to be able to change its rotational angle relative to the crankshaft and the torsional vibration damper. The torsional vibration damper is partially positioned in a corresponding annular recess in the belt pulley, creating an annular cavity in the recess between the torsional vibration damper and the belt pulley. An annular seal ring is positioned in the annular cavity and is arranged to close off at least a part of the annular cavity from the air surrounding the assembly.
