    摘要: The invention relates to a method and device for detecting and decoding a two-dimensional encoded pattern, e.g. of the Robust Encoding Pattern type (REP), even in case the pattern is applied on a non-uniform colored background of a surface of a substrate. The operations for decoding such an encoded pattern involve detecting the states of its symbols through a test pattern, checking that local differences between parameter values of the elements of the symbols are consistent with an allowed representation of the test pattern to assign via a one-to-one mapping the states of the symbols of the test pattern to the corresponding symbols of the encoded pattern, and decoding the encoded pattern based on the assigned representation of its symbols.

    摘要: A modular service station for servicing at least one inkjet printhead of an inkjet printing system, the service station comprising: a frame with mounted thereon at least one capping element and at least one wiping element, a means for horizontal movement of the at least one inkjet printhead between a printing position and a servicing position, the means for horizontal movement configured to enable a wiping process, a means for vertical movement of the at least one inkjet printhead, the means for vertical movement configured to enable capping, unclogging or purging processes in respect to the at least one inkjet printhead, and a waste ink tank in hermetic communication with the at least one capping element. A method of servicing an inkjet printhead of an inkjet printing system is also disclosed.

    摘要: The invention protects a content of a digital or physical document against forgery. It allows automatic detection of any modification in an arrangement of graphical symbols (e.g. a text) provided on a support (e.g. printed or displayed) with respect to an original arrangement by providing on the support reproducible verifiable data including a verification barcode, while eliminating redundancy between data inside the barcode and the graphical symbols, and resolving the problem of the size of the barcode when the size of the data for these graphical symbols is large.

    摘要: The disclosed scanner for detecting a decay time of light emitted by a luminescent material has a control unit operable to adapt the drive current, or the value of the drive voltage, powering its light source to accordingly adapt the intensity of excitation light delivered to the luminescent material so that its high sensitivity light sensor can reliably measure the luminescence light emitted in response to the excitation light, and thus accurately determine a corresponding decay time value.

    摘要: The present invention relates to the field of protecting value documents and value commercial goods against counterfeit and illegal reproduction. In particular, the present invention provides processes for producing optical effect layers (OELs) comprising non-spherical magnetic or magnetizable particles and comprising a motif made of at least two areas made of a single applied and cured layer, said motif being obtained by using a selective curing performed by irradiation with an actinic radiation LED source (x41) comprising an array of individually addressable actinic radiation emitters.

    摘要: Authenticating a mark having a marker that emits light under illumination, involving an obtaining of a light spectrum from the mark, the light spectrum having values, each value indicating a light intensity of the light emitted from the mark for a corresponding wavelength, an applying of a set of rules onto the values of the light spectrum to obtain a first result indicating whether the mark is authentic or not, an applying of statistical processing onto the values of the light spectrum to obtain a second result indicating whether the mark is authentic or not, and a generating of an output result indicating whether the mark is authentic or not from the first result and the second result.

    摘要: A method of marking and authenticating a manufactured item, comprising providing the manufactured item with a visible anti-counterfeiting indicium, marking with marking means the manufactured item with a visible alphanumeric string, marking with marking means the manufactured item with visible marking time data, and transmitting with data transmission and control means marking time data marked on the manufactured item and the alphanumeric string marked on the manufactured item. The method further comprises with computer database control means, receiving the transmitted marking time data and the transmitted alphanumeric string and storing in association in a database marking time information corresponding with the received marking time data marked on the manufactured item and alphanumeric information corresponding with the received alphanumeric string marked on the manufactured item. The method further comprises checking authenticity of the anti-counterfeiting indicium provided on the manufactured item, interrogating the database with the alphanumeric string read from the manufactured item to obtain marking time information for the manufactured item, and comparing the marking time information with marking time data read from the manufactured item to determine if they match. The method comprises determining the manufactured item as authentic if criteria are met, the criteria including that the checking step reveals an authentic anti-counterfeiting indicium and the comparing step determines a match.
