  • Patent number: 10768441
    Abstract: A new method of constructing a convertible virtual reality viewer on planar surface when in an unfolded state, or out of a box-type structure is described. Through its design of structural folds, the planar surface(s) can be configured into any shape such as, but not limited to, a package, box, container, mailer, and flyer of any material. Users of such a viewer download a software application onto a smart device and use this display apparatus to view a virtual image through a face plate, containing a pair of biconvex lenses. A viewer fashioned as such provides an environmental solution to reusing resources and limiting product waste by reusing product packaging as a virtual reality viewer with multiple uses. The planar surface(s) are intended for use as product packaging and/or mailer designed to be converted into a virtual reality viewer by the user.

  • Patent number: 9746590
    Abstract: A printed retroreflective film has a planar surface on a front side and a plurality of retroreflective elements on a back side. A halftone printed ink layer is deposited on the planar surface formed from uniformly spaced, discrete dots of deposited ink. The areas between the dots provide light-transmissive openings that receive incident light and transmit retroreflected light. The aggregate area of the dots forming the half-tone pattern preferably covers between about 60% and 90% of the area of the half-tone pattern. The use of such a halftone pattern of ink increases the reflectivity of the printed retroreflective sheeting by reducing the amount of light absorbed by the ink, and by reducing the amount of light scattered by the layer of ink. The use of such a halftone pattern of ink further obviates the need for an anti-light scattering topcoat or film over the front surface of the retroreflective sheet.

  • Patent number: 9188716
    Abstract: A security element for manufacturing value documents, such as bank notes, checks or the like, has an upper side on which there is formed a microcavity structure that has a multiplicity of adjacent microcavities configured as retroreflectors, wherein on the microcavities there is formed a structure causing a color effect. The microcavities are respectively configured such that they have a first region in which radiation incident on the upper side is singly reflected, and a second region in which radiation incident on the upper side is multiply reflected. The structure causing the color effect has a dispersion dependent on the angle of incidence, so that radiation singly reflected at the first region shows a different color effect, when viewed from the upper side, than radiation multiply reflected at the second region.

  • Publication number: 20150146280
    Abstract: The disclosure relates to the field of graphical elements and is directed to an optical effect layer (OEL), a device and a method for producing same. The disclosure provides an optical effect that is easy to detect as such and exhibits a viewing-angle dependent apparent motion of image features over an extended length if the viewing angle with respect to the OEL changes. An OEL includes a binder material being at least partially transparent and a plurality of particles dispersed within the layer. Each particle has a non-isotropic reflectivity and may be magnetic or magnetizable. The orientation of the particles forms an orientation pattern extending over a length within an extended surface of the OEL, such that the local average of an angle between (i) a straight line along an observed longest dimension within the corresponding cross-section shape, and (ii) said first direction x varies according to a function (?) of a position (P) along said first direction.

  • Publication number: 20150084327
    Abstract: An optical security component intended to be checked in reflection in a checking spectral band includes a layer that is reflective in the checking spectral band. The layer exhibits a structured zone that includes microstructures distributed spatially in a uniform manner over a whole of the structured zone so as to form an optical structure that is at least partially scattering in the checking spectral band. The microstructures have heights that are distributed according to a random function, modulated over the structured zone by a modulation function so as to form, after illumination of the optical security component at a given angle, an image identifiable by observation in reflection.

  • Publication number: 20150076808
    Abstract: An identification film and pattern having high transparency and a reflectance spectrum with respect to a particular wavelength and including photonic crystals patterned into a particular shape and an anticounterfeiting product including the same are disclosed. A highly transparent colloidal photonic crystal film is easily manufactured using photocurable colloidal suspensions. Even though a plurality of patterns (including sub-patterns) is formed in plural films, there is no reduction in optical characteristics such as transparency, reflectance spectra, and the like. Thus, a film patterned into a desired shape is manufactured and thus usability thereof is enhanced, and a plurality of reflectance spectra with various wavelength ranges is provided and thus identification capability or security is enhanced.
