摘要:
Disclosed is a structure for preventing counterfeit, falsification or reuse, including a metal layer, a photoconversion pattern layer including a plurality of photoconverting nanoparticles formed on the metal layer, a metal pattern layer placed on the metal layer and the photoconversion pattern layer, and an adhesive film placed on the metal pattern layer. Accordingly, the structure for preventing counterfeit, falsification or reuse according to the present disclosure allows a pattern indicating a genuine product to be easily identified with an eye through infrared light irradiation, and is fundamentally impossible to re-assemble after deformation of the structure caused by disassembly of a packaging container, thereby preventing counterfeit, falsification or reuse.

A vehicle engine is provided that includes an exhaust manifold configured to emit a first emission. A heat shield is positioned proximate the exhaust manifold and has a shield substrate defining an aperture. An indicator is positioned over the aperture with a support substrate and a semiconductor layer. The semiconductor layer is configured to absorb the first emission and emit a second emission.

The present invention relates to a labeling element for items, which on a surface thereof is formed with a plurality of pixels with periodic lattice structures, in particular linear lattice structures. Lattice structures with in each case one structural period A and an alignment of the structural elements, which are aligned to one another in particular in a linear parallel manner, at an angle φ with respect to an axis of reference are formed in individual pixels such that when the pixels constituting the labeling element are irradiated with electromagnetic radiation, preferably monochromatic electromagnetic radiation, an image of the labeling element is created on an detector array or a surface, by means of images of at least one order of diffraction of the electromagnetic radiation diffracted by pixels which can be used for identification of the respective labeling element.

A method of illumating an item is disclosed. The method includes applying adhesive to the item, interspersing a taggant in the adhesive, illuminating the item with an excitation signal, sensing luminescence emitted by the taggant in response to illumination by the excitation signal, and determining the authenticity of the item based on the sensed emitted luminescence. The item can include any item benefited by authentication, and can include a postage stamp. A method of customizing an item is disclosed. This can include the steps of preparing a substrate, applying a security feature to the substrate, printing non-customized information on the substrate, receiving image information, and printing the image information on the substrate.

A label (1) of this invention includes an optical function layer (13) configured to pass light of a certain wavelength, a light absorption layer (15) facing the optical function layer (13) and configured to absorb the light of the wavelength, and a light scattering layer (12) intervening between the optical function layer (13) and the light absorption layer (15) and including hollow bodies configured to scatter the light of the wavelength. The light scattering layer (12) is configured to raise a transmittance at the wavelength upon receiving external heat.
摘要:
A label includes an optical function layer configured to pass light of a certain wavelength, a light absorption pattern facing one major surface of the optical function layer and configured to absorb the light of the wavelength, and a light reflecting layer facing the other major surface of the optical function layer and configured to reflect the light of the wavelength. The light reflecting layer is configured to raise an absorbance at the wavelength when heated.
摘要:
The present invention relates to a marking of polymeric liquid crystal material having determined optical characteristics allowing its authentication and reading by a machine and its authentication by the human eye. The marking is applied onto an item, good or article by a variable information printing process. The marking is in the form of indicia representing a unique code which allows for an easy authentication by the human eye and a secure tracking and tracing of the marked item, good or article throughout its life cycle.
