Patent CA-2096879-A1 (CA)
Inventor: RAY RAJARSHI
IPC: G02B5/08
Filed: 1993-05-25
Abstract: The contrast of an LCD cell (12) is enhanced by the use of a gradient index plate mirror (16',16") positioned behind the cell to reflect light from a light source (14',14") through the cell in a well-collimated beam. The mirror (16',16") is formed of an optical plate (34',34") having first and second major surfaces (36',36") and (38',38"), the latter having a reflective coating (40',40") thereon. The optical plate (34',34") has a gradient index of refraction which increases from its first to its second major surface. As a consequence, the light entering the plate and reflected back therethrough is refracted so as to be bent closer to the plate normal (42',42"), causing the light leaving the mirror and entering the LCD cell to be well collimated, which is desirable for improving the display contrast.

Title: Anti-decubitus mattress pad
Inventor: DINSMOOR JOHN C III
IPC: A61G7/057
Filed: 1992-08-28
Abstract: A mattress pad (1) is multi-layered and includes a cover or casing (5, 7) containing interior strata of a plastic film (17) layer atop a fluid bladder layer (19) supported on an underlying layer of foam (21). The reduction of the lateral shearing forces on a user of the pad is accomplished by oversizing the plastic film layer (17) and fluid bladder layer (19) on the underlying layer of foam (21) and by positioning microbeads between the plastic film layer (17) and fluid bladder (19) layer to dramatically reduce the friction drag or lateral shearing forces between the layers.  Normal pressures and forces are reduced by oversizing, modifying the configuration, filling, and size of the discrete fluid pouches (41, 41', 41") of the fluid bladder layer (19), and varying the spring characteristics of the support columns (49) in the underlying foam layer (19) by hollowing them out to different degrees (53, 53'), adjusting their spacing, selectively tying adjacent columns (49) together.

Abstract: REFLECTIVE PLASTIC OPTICS WITH  IMPROVED OPTICAL PROPERTIES                               ABSTRACT Novel mirror materials and fabrication processes are used to produce extremely low cost reflective optical components. Reflective mirrors are made using injection molded filled plastic. Reinforcing filler materials are added to the plastic resin prior to molding. Subsequent to injection molding, the plastic mirrors are coated with alumi-number other infrared reflective coating by means of vacuum deposition, for example, to produce a reflective surface. Additives or external metallization provide for control of thermal conductivity. The mirrors produced in accordance with the present invention may be used for 8-12 or 3-5 micron infrared imaging. However, the present plastic mirrors, when appropriately coated, may also be used in other wavelength bands. By employing the principles of the present invention, low cost mirrors with improved thermal stability and optical quality are achieved. The principle advantage of the present invention is a dramatic reduction in cost possible over reflective elements manufactured using conventional precision optical fabrication methods. The present mirrors have improved optical properties, primarily mirror figure and thermal stability.
