Abstract: A tensioning system includes a layer of a device and a flexible overlay film that is configured to cover the layer of the device. A tensioning mechanism is configured to tension the flexible overlay film against the layer of the device throughout a periphery. The tensioning mechanism also is configured to allow movement of the flexible overlay film in two dimensions.

Abstract: A rear projection display device. The display device includes a screen and a base to which the screen is mounted. The base includes a plurality of vents to allow air to flow in and out of the base, a heat source, and an air movement device to move air from near the screen, past the heat source, and out through the vents.

Abstract: A method and system for a thermal architecture and user adjustable keystone in a display device is described. The system includes a screen, a lens to project images, and one or more mirrors to reflect the images projected by the lens to the screen. A mirror assembly to adjust the images projected on the screen includes a first frame to pivot about a first axis, a second frame pivotably mounted in the first frame to pivot about a second axis, and a mirror moveably mounted in the second frame to reflect an image on a screen of a display device. The mirror is adapted to pivot about the first axis and the second axis via the first frame and the second frame to adjust the images on the screen. The base to which the screen is mounted has a thermal architecture that includes a plurality of vents to allow air to flow in and out of the base and an air movement device to move air from one or more heat sources away from the screen and toward the vents.
