Abstract: A dust cover for an electronics assembly is provided. The dust cover may have a planar body portion having a planar top surface, a plurality of side walls extending from the planar body portion in a direction substantially perpendicular to the planar top surface and at least partially defining a plurality of compartments, a first removable cover connected to the planar body portion, positioned over a first compartment, and configured to be removable without a tool, and a curved airflow surface connected to the planar body portion. Each side wall has a proximate end connected to the planar body portion and a distal end offset from the planar body portion, the distal ends form a reference plane offset from the planar body portion, and at least a portion of the curved airflow surface is interposed between the reference plane and the planar body portion.

Abstract: The present invention provides a system for synchronising a plurality of electronic gaming machines in electronic communication with each other. Each electronic gaming machine has a lighting device for displaying a light presentation on the electronic gaming machine and a lighting controller in electronic communication with the lighting device for controlling the display of the light presentation by the lighting device. The lighting controllers of the electronic gaming machines are in electronic communication with each other. A master lighting controller for controlling the lighting controllers transmits one or more signals to the lighting controllers so that the lighting devices of the electronic gaming machines (1) are synchronised to display the same light presentation simultaneously. A method is also provided.
