  • Patent number: 9432017
    Abstract: In one embodiment, a kit for making a touch-sensitive personalized display includes a first medium that is foldable according to score lines to form a cavity. The first medium includes an adhesion surface to receive a personalized second medium, and a back surface opposite the adhesion surface. The second medium includes a personalization surface to receive a user selected-image, and includes a rear surface opposite the personalization surface to adhere to the first medium's adhesion surface. The kit includes a conductive touch sensing system to detect a user touch at the personalization surface and to trigger an action at an electronic device responsive to detection of the touch.

  • Patent number: 6902643
    Abstract: A thermal transfer overcoating technology for reducing overcoat tags. Skewing the interface between a carrier ribbon to coated document at the peeling of the carrier from the coated document concentrates the forces at the interface to a smaller region of the document edge. Moreover, tensioning the document at the interface changes the forces at the interface from peeling type to tensile type.

  • Publication number: 20020195198
    Abstract: A method and apparatus for separating a laminate carrier from a laminated media sheet involves pulling the carrier away from the laminated sheet around separator bar having a sharp corner so that the separated carrier follows a path which makes an angle of not less than about 85° with the laminated sheet from which the carrier has been removed. The corner preferably has a radius no greater than about 0.50 mm.

  • Patent number: 6475322
    Abstract: A method and apparatus for laminating media sheets to remove trailing edge coating debris as the carrier is removed from the laminated sheet involves imparting a transverse force to the laminated sheet to cause the sheet to abruptly straighten as the trailing edge of the sheet passes by a corner of a carrier separation bar at which the carrier is removed. The transverse force may be imparted by guides such as rollers defining a serpentine path through which the laminated sheet must travel.
