Abstract: An air duct is described herein. The air duct includes a duct housing having a first end and a second end and at least one vent disposed between the first end and the second end. The air duct also includes a plurality of dividers disposed between the first end and the second end and a plurality of channels. The plurality of channels are disposed between the first end and the second end and are derived from the plurality of dividers. The plurality of channels are to cool a first component and a second component of a computing device, wherein the duct housing is to encompass the first component and the second component. The duct housing is positioned with the first component located upstream of an air flow and the second component disposed downstream of the air flow.

Abstract: A visual signaling device which has a horizontally extending lamp which is connected to an electrical housing and which is surrounded by a reflector body. The reflector body has a pair of oppositely extending horizontal parabolic troughs and a downwardly extending horizontal trough. Each trough has an input opening adjacent the lamp, an output end opening, and a front opening. Each trough is defined by a generally planar back wall and a pair of opposed side walls. Each side wall is horizontal from the back wall to the front opening and parabolic relative to the central longitudinal axis of the lamp from the input opening to the output end opening. In a second embodiment of the invention, the reflector has an upwardly extending parabolic trough.
