Abstract: An arbitrary surface optical element, such as a mirror for use in a rear projection television, includes a non-optical portion and an optical portion. The non-optical portion circumscribes the optical portion and has a thickness greater than the optical portion. Accordingly, the two portions cool at approximately the same rate, thereby minimizing warpage from differential cooling.

Abstract: An assembly for use in a projection system includes a plurality of optical elements, such as one or more mirrors, a light engine, and a screen, and a monolith. The optical elements are coupled to the monolith to provide a central element of reference, thereby enabling alignment based on the central element of reference.

Abstract: A method of manufacture of a display which creates a single axis assembly process where all components and subassemblies are added to a single part—the back bucket. The bucket is placed on an assembly line first and all other components are added to a receiving side, top down. This back bucket provides connection and alignment details for the remaining parts of the assembly, including internal electronics.

Abstract: The present invention relates to an enclosure that protects an operational data storage device (preferably a common disk data storage devices with an IDE interface) from fire, flood or other hazards. The preferred embodiment comprises an enclosure which is water resistant and heat transfer protected to preserve the disk data storage device in the event of disaster involving flood or fire. Insulation, including phase change materials, are used to maintain internal temperature during normal operation and during fire conditions, so as to meet the thermal test portion of UL 72, Class 125, one hour, and the disk data storage device temperature does not exceed 125° C. The enclosure of the preferred embodiment manages humidity to an internal RH at 80% or below.
