Abstract: Disclosed are a method, a device and/or a system of cast vinyl film and, more particularly, to a method and system to provide a repositionable translucent cast vinyl film with an air egress adhesive layer. In one aspect, a method includes mixing a solvent based polyvinyl chloride (PVC) organosol with a stabilizer and an additive to get a desired shade of pellucid tint of a translucent thermoplastic stretch wrap film. Further, the method includes casting the polyvinyl chloride (PVC) organosol onto a film carrier and moving the film carrier through a plurality of ovens at varying temperatures to care into a solid film. The cured solid film is laminated to an air-egress liner casted with a solvent-borne acrylic pressure-sensitive adhesive to provide ease of installation. The adhesive includes an air release patterning to allow escape of air from back of the film while repositioning the film around a complex shaped surface.

Abstract: An optical unit includes: a light source; a rotating reflector configured to be rotated in a single direction with the rotational axis as the center of rotation while reflecting light emitted from the light source; and a projector lens configured to project light reflected by the rotating reflector in the light irradiation direction. The projector lens has a first lens region LR1 that defines the first focal plane and a second lens region that defines the second focal plane that differs from the first focal plane. The light source is arranged such that, when the rotating reflector is set to the first rotational position, its virtual position is in the vicinity of the focal plane, and such that, when the rotating reflector is set to the second rotational position, its virtual position is in the vicinity of the focal plane.

Abstract: A trim component, such as a grill of a vehicle, includes a substrate having a 3-dimensional shape and defining a disrupted reflective surface including a plurality of facets over a curved surface. Each of the facets is configured to reflect an incident light beam in a common direction, for example, toward a given target. A reflective coating, such as a chrome plating layer, overlies the disrupted reflective surface. The facets may have similar shapes and/or be arranged in a repeating pattern, but with one or more irregular features. The sizes, shapes, and/or orientation direction of the facets may varying in a gradient based on the curvature of the curved surface. The trim component also includes a light source to illuminate the disrupted reflective surface. The light source may be hidden so it is not directly visible to a viewer, but instead is reflected by the disrupted reflective surface.
