Abstract: An apparatus and heat management mechanism are described. The apparatus includes an outer casing enclosing at least one heat generating electronic structure, such as a plurality of electronic components included on at least printed circuit board, the outer casing having an inner surface and an outer surface. The apparatus and the heat management mechanism further include a heat dissipation structure thermally coupled to the heat generating structure or printed circuit board, the heat dissipation structure forming an open-ended columnar channel, the open-ended columnar channel allowing air to flow within the heat dissipation structure in a direction parallel to a surface of the heat generating structure or printed circuit board.

Abstract: A projection display with a shield surrounding an output end of a light engine to prevent dust and stray light from entering a light box of the projection display is described. The projection display includes a cabinet, a light engine mounted in the cabinet and having an output end and an electronic end, a removable front cover mounted on the cabinet covering the light engine, and a shield surrounding the light engine between the output end and the electronic end.

Abstract: A projection display is described having two structural support arms for mounting the projection display on a stand or on a bracket. A light engine generates a light pattern to be displayed by the projection display. A bridge plate is positioned between the two support arms and the light engine is mounted on the bridge plate.

Abstract: A projection display with a cabinet having a back wall with an outside face and an inside face, two support arms supporting the cabinet extending vertically along the outside face of the back wall of the cabinet and spaced apart a distance approximately equal to the width of the mirror is described. The cabinet has four raised pads formed on the inside face of the back wall proximate the support arms for locating the mirror, and the mirror is biased against the four pads to hold it in a vertical position.

Abstract: A hinge for mounting a projection display screen (10) to a cabinet (20) from the front of the screen is disclosed. A cabinet hinge part (40) is attached to the cabinet (20), and a screen hinge part (50) is attached to a screen frame (12) having the screen (10) mounted on it. Both the cabinet hinge part (40) and the screen hinge part (50) are elongate, stiff members, with one of the cabinet hinge part (40) and the screen hinge part (50) having an arcuate slot (42) extending along its elongate dimension and the other of the cabinet hinge part (40) and the screen hinge part (50) having an arcuate projection extending along its elongate dimension, where the arcuate projection (52) is pivotally interlockable with the arcuate slot (42).

Abstract: A projection display is provided having visible surfaces and concealed surfaces during normal operation. The projection display comprises a jack panel having one or more connectors for making electrical connections to the projection display, and the jack panel is accessible from at least one visible surface and at least one concealed surface.
