  • Patent number: 10354963
    Abstract: A pattern of information is detected in a thin-film electrical element including a plurality of thin-film layers on a substrate, the plurality of thin-film layers overlapping in an encoding region to form an optical layer structure. At least one of the thin-film layers in the optical layer structure includes an embedded information-encoding pattern. The thin-film electrical element is illuminated with an incident light beam from a light source thereby producing an optically-detectable interference image including the embedded pattern of information. An image capture system is used to capture an image of the optically-detectable interference image, and a data processing system is used to analyze the captured image to detect the embedded pattern of information. One or more actions are initiated in response to the detected pattern of information.

    Abstract: A security element for integration into a document. The security element has a transparent substrate. An array of lenses is disposed on the first side of the substrate. A field of elementary patterns observable through the array of lenses is disposed on the second side of the substrate. A transparent lacquer partially covers the array of lenses. The lacquer takes the form of at least one macroscopic pattern, which locally cancels out the effect of the lenses, thereby allowing an observation of the field of underlying elementary patterns tin halftone. The macroscopic patterns are not spatially coordinated with the field of elementary patterns.

  • Patent number: 8696032
    Abstract: A security device comprises a substrate having a transparent region (1). At least one optical element (2, 3) is provided in part of the transparent region, the optical element causing an incident off-axis light beam transmitted through the optical element to be redirected away from a line parallel with the incident light beam whereby when the device is viewed in transmission directly against a backlight, the presence of the optical element cannot be discerned but when the device is moved relative to the backlight such that lines of sight from the viewer to the transparent region and from the transparent region to the backlight form an obtuse angle (?) at which redirected light is visible to the viewer, a contrast is viewed between the part of the transparent region including the optical element and another part of the transparent region.

  • Patent number: 8684415
    Abstract: The present invention relates to improvements in security devices that can be used in varying shapes and sizes for various authenticating or security applications, particularly an optically variable security device utilizing liquid crystal materials. The security device includes a liquid crystal layer (11), an at least partially absorbing layer (12) adjacent at least a part of one side of the liquid crystal layer (11), and at least one customizing region (13) which is adjacent at least a part of an opposite side of the liquid crystal layer (11) to the absorbing layer (12) in selected regions. The at least one customizing region (13) modifies the color shifting properties of the liquid crystal layer (11) such that at least two contrasting optically variable regions are provided by the regions covered by the at least one customizing region and regions not covered by the at least one customizing region.

  • Patent number: 8684416
    Abstract: Labels that are conducive to the detection of bar-codes and other indicia having varying spectral emissivity values are provided. The labels include a substrate, a background layer, a thermally conductive layer and an adhesive layer. The background layer is preferably similar in visual appearance to the indicium that the label is to receive. Meanwhile, the thermally conductive layer is made from a material with high thermal conductivity that is used to substantially equalize the temperature across the label surface, thereby enabling a faster and cheaper detection of transitions of differential emissivity on the indicium surface. The adhesive layer is used for attaching the label to a document or other product.

  • Patent number: 8672361
    Abstract: A security element, comprising at least two contiguous areas having an identical or different coloring which can vary depending on the inclination of the incidence and, therefore, reflection of direct light or depending on the type of incident light. The security element also has a single graphic marking which crosses with continuity the two areas having variable coloring so that the graphic marking straddles the two areas so that it is perfectly aligned, without having discontinuities of any kind. Moreover, the effect of this graphic marking is perfectly visible both when the security element is viewed from the recto and when it is viewed from the verso.

  • Patent number: 8616461
    Abstract: A printed dynamic optical illusion printed on a printing device using a plurality of colorants, wherein one or more of the colorants are appearance mutable colorants having spectral characteristics that can be controllably switched between a first colorant state and a second colorant state by application of an appropriate external stimulus, and wherein one or more mutable portions of the optical illusion image are printed using at least one appearance mutable colorant. The mutable portions are controllable such that when they are in a first appearance state the printed optical illusion image has a first illusion state, and when they are in a second appearance state the printed optical illusion image has a second illusion state, thereby changing the optical illusion image from the first illusion state to the second illusion state so as to affect the perception of an optical illusion by a human observer.
