Abstract: An optical system including at least a first lens, a partial reflector and a reflective polarizer is described. The optical system has an optical axis such that a light ray propagating along the optical axis passes through the first lens the partial reflector and the reflective polarizer without being substantially refracted. At least one major surface of the optical system is rotationally asymmetric about the optical axis. A major surface of the optical system may have a first portion defined by a first equation and a second portion adjacent the first portion defined by a different equation. The first lens may have a contoured edge adapted to be placed adjacent an eye of a viewer and substantially conform to the viewer's face.

Abstract: Optical systems for displaying an image are described. The optical systems include spaced apart first and second optical lenses. A partial reflector is disposed on and conforms to a major surface of the first optical lens where the major surface can have a best-fit spherical radius of curvature in a range from 20 mm to 200 mm. A reflective polarizer is disposed on and conforms to a major surface of the second optical lens where the major surface can have a best-fit spherical radius of curvature in a range from 14 mm to 250 mm. A retarder layer is disposed between the reflective polarizer and the partial reflector. The first optical lens can have an optical birefringence of less than 15 nm/cm and the second optical lens can have an optical birefringence of greater than 15 nm/cm. A method of fabricating an optical assembly is described.

Abstract: A measuring and dispensing container having a flexible walled reservoir chamber, a measuring and dispensing chamber and a conduit for transferring liquid from said reservoir chamber to said measuring and dispensing chamber. The reservoir is provided with a non-squeezable handle by which it can be grasped when tilting the container to dispense liquid from the dispensing chamber so as to reduce the risk that excess force applied to the reservoir by a hand holding it will squeeze more liquid than intended into measuring and dispensing chamber. Such handle may be formed by reinforcement of at least one wall of the reservoir to provide sufficient rigidity to prevent squeezing at the reinforcement or by providing a “cut-out” in the reservoir chamber through which a user's fingers may pass and providing reinforcement on or in one or more walls of the reservoir chamber proximate to the cut out.

Abstract: A protective film includes a base layer and a wear layer, the wear layer comprising a UV cured hardcoat resin, and the UV cured hardcoat resin comprising surface modified silica nanoparticles. The protective film may comprise a pressure sensitive adhesive for adhesion to a floor. The protective film may be used, for example, as a protective floor finish.

Abstract: A container for measuring a predetermined amount of liquid and dispensing that measured amount. The container includes a reservoir chamber, a measuring and dispensing chamber, and a conduit or tube for transferring liquid from the reservoir chamber to the measuring and dispensing chamber. The reservoir chamber has flexible walls which can be squeezed to drive liquid from the reservoir chamber into the measuring chamber. The passage from the reservoir to the measuring and dispensing chamber is configured and its outlet arranged so that liquid entering the chamber flows down a wall thereof.

Abstract: Composite articles having a cosmetic layer, a structural layer comprising a fiber reinforced resin, and a compressible layer positioned between the cosmetic layer and the structural layer are described. The cosmetic layer has a Young's modulus of at least 1.0 GPa and the compressible layer has a Young's modulus of less than or equal to 50 MPa. Print-through control layers having a compressible layer and at least one skin coat are also described, as are methods of forming composite articles and methods of controlling print through.
