Abstract: A front projection screen is provided having a first portion of material and a second portion of material. The first and second portions of material may have an undercut edge profile, and the first and second portions of material may be perforated, such that the perforations allow the first and second portions of material to be at least somewhat acoustically transmissive while substantially maintaining optical efficiency from the front side of the front projection screen. Such optical efficiency has particular utility in stereoscopic projection applications utilizing polarized encoded light.

Abstract: An immersive dome includes a number of novel features designed to enhance the performance of the immersive dome over presently-known immersive dome environments. Projectors are mounted in a multi-tier tower, out of sight beneath a viewing platform positioned to provide optimal wrap-around viewing. The projection surface consists of open-cell foam that allows passage of behind-surface sound into the dome while allowing unwanted ambient noise within the dome to escape. A visually-reflective coating, in conjunction with the open cell structure, provides a textured surface that acts as a micro-baffle and suppresses cross-reflection of projected imagery.

Abstract: A cinema screen may include a housing including at least one of wood and polymer and configured to hold the cinema screen by at least one of gluing and pinching. The screen may include a metalloplastic multi-layer film coupled to the housing and have a relatively small thickness. The multi-layer film may also have a bottom layer that may be translucent and other layers of multi-layer film may be transparent. The screen may also include a plurality of lamps to provide light. The multi-layer film may be configured to diffuse the light, which may be softly filtered thereby to reduce contrasts, and increase a quantity of light information in front of and behind the cinema screen. The light information may vary with a greater softness. The multi-layer film may also be configured to provide relief image playback accuracy.

Abstract: Disclosed herein is a projection screen. The screen includes a soft thin elastic transmission sheet having an elongation rate of 50% or more and high transmissivity, the elastic transmission sheet constituting a front surface of the screen, and a thin image sheet for focusing an image projected from a projector, the image sheet constituting a rear surface of the screen. The image sheet may serve as a transmission sheet or a reflection sheet. The image sheet may be directly formed at the screen, or the image sheet may be a hard film attached to the rear of the elastic transmission sheet. A vibration plate is disposed at the outside of the image sheet. Consequently, incident image is transmitted or reflected without any interference with external light, and therefore, it is possible to increase the brightness of the screen by two to five times as compared to a conventional screen.

Abstract: A projection screen comprises a film having a projection side and provided with a number of passages adapted for permitting emitted sound waves to pass through said film. The projection screen is characterized in that these passages are arranged in such a manner that, if alignments can be detected, at least the principal ones have an angle that is not zero with regard to the vertical and horizontal edges of the screen.

Abstract: A system (and its methods of use) for collecting and displaying images so as to create a visual effect and, more particularly but not by way of limitation, a three-dimensional visual effect.

Abstract: In a mirror with a non-reflective portion provided within its reflective mirror surface as an information provider the portion is transparent and is backed by a display. The display has a moving image or has a colored image representation. Preferably at least one loudspeaker is connected to the display behind the mirror surface. That loudspeaker can also be connected to an input device.

Abstract: A window unit includes a window frame defining a frame perimeter and a window located within the frame perimeter. The window includes a display surface adapted to receive a display image.

Abstract: This invention provides methodology for the measurement of both low and high levels of scattered radiation produced by decorative and barrier coatings and plastics. Measurements of low levels are especially important for coatings used in automotive applications. The method is based on the illumination of the sample with radiation and collection of only the portion of the radiation scattered from the coating before, during and after the testing step and relating the optical signal from the tested portion of the sample material to the untested portion of the material and/or a standard. Through the practice of the invention, a large number of coating samples, as in an array, may be analyzed for their optical quality, principally haze, either after coating and curing, and/or after subjection of such coatings samples to elongation stresses, and/or abrasion testing, solvent exposure, hydrolytic stability testing, and temperature exposure.

Abstract: A motion-picture screen for projecting an optical image, which comprises a weaved knit having an adequate air permeability. One surface of the weaved knit is coated with a colored material so as to keep a high acoustic permeability concurrently with shutting the light from a wall or the like existing at the rear side of the screen. The other surface of the weaved knit is used as a surface onto which the optical image is projected by a projector, thereby providing an excellent contrast and a high image quality on the screen.
