Abstract:
A method (1) for providing matrices (2) for embossing polymeric films (3) and the like, particularly for imprinting microscopic identification strings and images (4), consisting of the following steps: A) providing a uniform background diffraction grating (5) on a flat plate (6) by means of a standard holographic technique; B) subjecting the flat plate (6) to at least one pulsed and localized energy beam by means of a procedure comprised among ablation, vaporization and melting of portion of material that constitutes the plate (6) in the neighborhood of the at least one point of incidence of the beam; C) repeating the exposure (B) to pulsed and localized energy beams according to a sequence of consecutive dots arranged in the configuration of the image of the element to be imprinted (4).
Abstract:
A device (1) for acquiring symbols, such as bar codes and the like, for digital photo-video units and the like, comprising at least one supporting body (2), which can be coupled detachably to a digital photo- video unit (A) substantially at the lens (O) and is provided with an internal cavity so as to allow the stroke of the lens (O), at least one light conveyance element being associated with the supporting body (2) and being adapted to convey the light signal emitted by a light source at a reference plane of the device (1) on at least one symbol, so as to ensure optimum lighting of the symbol at the time of image acquisition.
Abstract:
A method for providing a locally rough surface which is spatially structured on micrometric and/or nanometric scale and is formed by a substrate, so as to obtain a product. The method comprises the steps of flattening and/or smoothing the rough substrate in preset regions.
Abstract:
A device for monitoring the temperature to which a product has been exposed, comprising at least one spatially structured element (1), which is constituted by a material which indicates a preset level of temperature (Tes) and a preset exposure time interval (Tis), the spatially structured element (1) being adapted to be applied to the product to be monitored. The indicator material can be selected among materials which detectably change their morphological and/or structural and/or chemical and/or physical state once the material is placed in a condition in which it can absorb a preset amount of heat. The method for monitoring the temperature to which a product has been exposed comprises the selection of the indicator material, which is constituted by one or more substances capable of changing state at the preset threshold temperature (Tes) and the formation of the spatially structured element (1) having a total volume adapted to ensure a detectable change of state when a time interval (Δt) elapses which is equal to, or longer than, the preset time interval (Tis), the element (1) being adapted to be applied to the product to be monitored.
Abstract:
A system, a method and a marking for identifying and validating individual product elements within a group of product elements, the system comprising identification codes (1) which can be reproduced on each individual product element (EP), a medium (S) which contains encrypted digital information (2) which can be read by means of a suitable reader, the medium (S) being applicable to the group of product elements, the encrypted digital information (2) comprising a first software in encrypted form which is suitable to generate the identification codes (1), the system further comprising an electronic unit (4) provided with means (3, 6) for reading and decrypting the encrypted digital information (2), means (3, 5) for acquiring the identification codes (1) reproduced on each individual product element, and means for comparison between the acquired identification codes (1) reproduced on each individual product element (EP) and the identification codes that can be generated by the first software.
Abstract:
A device and a corresponding method which allows to protect, preserve and activate (making it sensitive to external agents) a sensitive element, which changes its morphology and/or produces phase segregations following exposure to external agents.
Abstract:
A system for authenticating products and/or packages, comprising a unit (1) for acquiring primary configurations (16) which represent meaningful images and for generating secondary configurations (17) for the authentication marking of products and/or packages (P); a unit (2) for applying the generated secondary configurations to a product and/or package; and a unit (3) for recognizing the secondary configurations (17) applied to the product and/or package (P). All the units (1, 2, 3) are provided with means (7) for mutual connection in an active configuration for transmitting digital data. A method for authenticating products and/or packages comprises the acquisition of primary configurations (16) which represent meaningful images; the generation of secondary configurations (17) for marking; the application of the generated secondary configurations (17) to a product and/or package (P); and the recognition of the authenticity of the product and/or package.
Abstract:
A method for providing a thin film (2) that is spatially structured on a submicrometric or nanometric scale, formed by a material (3), on a substrate (1), so as to obtain a product (9); the method comprises the steps of dispersing the material (3) in the substrate (1) in order to obtain a mixture (10); modeling the mixture (10) to form on a surface (10a) of the mixture (10) protrusions (7) and recesses (6); conditioning the mixture (10) by smoothing any surface roughness thereof; by doing so, the material (3) emerges on the surface only at the protrusions (7) of the mixture (10).
