Abstract: 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.

Abstract: 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.

Abstract: An endosteal guide pin for preparing a guide path for the implantation of a pedicle or orthopaedic screw into a patient's bone. The pin has a head intended to be provisionally implanted in a bone and a guide rod, coaxial with and rigidly secured to the head, ending in a free end intended to be at least level with the skin surface of the patient when the pin is in the implanted position in the bone. The pin has a first coupling part intended at least to secure the pin to and release the pin from at least one portion of a positioning trocar and a second coupling part intended at least to secure the pin to a removal trocar. Also, a trocar for positioning a guide pin, which trocar incorporates the guide pin, and to a trocar for removing the pin.

Abstract: The invention relates to a method for authenticating a security marking including at a long afterglow compound capable of emitting long afterglow luminescence light in a given wavelength region, the method allowing to detect a presence and an amount of said long afterglow compound based on comparison of a measured initial intensity value of a spectral component of the emitted light within said wavelength region and associated afterglow time with corresponding reference values representative of a reference amount value of a genuine long afterglow compound. The invention also relates to a reader and system operable to implement the steps of the method.

Abstract: The invention notably relates to generating a measure of authenticity of an object (20) comprising a surface (30) comprising or covered by a non-uniform preexisting layer (40). A marking (50) has been printed on the surface (30) so that a property of the preexisting layer (40) is detectable through at least part of the marking (50).
