Patent number: 11945253Abstract: A security device includes an arrangement of image icon focusing elements, wherein each image icon focusing element of the arrangement of image icon focusing elements is associated with a focal path. The device further includes an image icon layer with one or more image icons associated with a first characteristic color and one or more image icons associated with a second characteristic color and one or more regions between the image icons comprising a volume of substantially colorless material. At a first viewing angle, a color is visible through each image icon focusing element, and the color visible through each image icon focusing element at the first viewing angle is based on one or more of the first characteristic color, the second characteristic color, or the substantially colorless material.Type: GrantFiled: May 20, 2020Date of Patent: April 2, 2024Assignee: Crane & Co., Inc.Inventors: Nancy J.

Patent number: 5434707Abstract: Plastic lenses having substantially no optical power and a light-polarizing layer therein are prepared by shaping composite laminate of the light-polarizing layer between opposed sheets of thermoplastic material by heating and pressing the laminate between opposed shaping molds (platens), the platens having predetermined radii of curvature for the production of a lens having substantially no optical power. Shaping is effected under conditions of heating and pressing sufficient to cause flow of the thermoplastic sheets and conformation thereof to the respective curvatures of the forming surfaces of the platens. The lenses are especially suited as sunglass lenses for spectacles.Type: GrantFiled: September 14, 1993Date of Patent: July 18, 1995Assignee: Polaroid CorporationInventors: William H.
