Abstract:
La présente invention concerne un dispositif radiofréquence (1) comportant : au moins une feuille (2) d'un substrat; au moins une antenne booster (3) filaire, formée avec un fil conducteur électriquement isolé, comportant au moins une spire, ayant deux extrémités reliées électriquement entre elles dans une zone de connexion (10).
Abstract:
La présente invention concerne une structure (1) comportant : au moins un substrat en matière fibreuse (2), éventuellement au moins une couche de surface déposée sur une face du substrat, une pluralité d'hétérogénéités (3) du substrat et/ou de la couche de surface éventuelle, dispersées de manière aléatoire au sein du substrat et/ou de la couche de surface éventuelle, au moins une information d'authentification et/ou d'identification ayant un lien avec au moins une caractéristique spatiale et/ou physique d'une partie au moins desdites hétérogénéités.
Abstract:
L'invention concerne une feuille identifiable par spectroscopie proche infrarouge comportant au moins un composant NIR sensible à un rayonnement dans le proche infrarouge et qualifiable et/ou quantifiable par spectroscopie proche infrarouge selon une calibration spécifique. Elle concerne aussi la méthode d'authentification de cette feuille.
Abstract:
La présente invention concerne un papier sécurisé (1), caractérisé par le fait qu'il comporte : au moins une couche fibreuse (2), - au moins une puce électronique (3) intégrée à la couche fibreuse (2), cette puce (3) comprenant une mémoire dans laquelle est mémorisée au moins une première clé servant à l'authentification du papier sécurisé, la puce étant agencée pour altérer, notamment effacer, la première clé en cas de tentative d'accès forcé à la puce, de manière à rendre impossible l'authentification ultérieure du papier sécurisé (1).
Abstract:
The present invention relates to the field of paper and relates to a sheet including a high-definition high-contrast multitone watermark having areas of pronounced brightness. Such watermark is particularly obtained by means of a part (4) including a surface (5) having a raised area and perforations (6). The perforations (6) are such that making the cross-section thereof, at a given distance from the draining surface, directly depends on said distance. The present invention also relates to the method for manufacturing said part that is used for forming one such watermark, to the part itself, and to the use of said part when forming a watermark.
Abstract:
The invention relates to a security element (1) which comprises a substrate (6) bearing at least the following elements on at least one of the faces thereof, namely: an optical structure (4) producing at least one image of at least one pattern (5) and/or producing image points of a light source illuminating the optical structure; and an adhesive (14), in particular a heat-sealable varnish, covering at least part of the aforementioned face of the substrate (6) without fully covering the optical structure (4).
Abstract:
The present invention relates to a process for manufacturing a sheet material, comprising at least two fibrous plies juxtaposed one on top of the other, said process comprising the following steps: a first paper ply, which includes at least one elongate region of zero thickness, is produced by filtration of an aqueous suspension of fibres on the wire of a first cylinder mould or of a former, an at least partially transparent element being inserted into said ply during the formation of said ply, and such that said at least transparent element is placed at least in said elongate region of zero thickness; a second paper ply is produced on the wire of a second cylinder mould so as to form at least one recess in said second ply; the two plies are joined together so that at least one recess in the second ply is located facing said at least one elongate region of zero thickness of the first ply comprising an at least partially transparent element; and thus a window is formed and the structure thus obtained is dried.
Abstract:
The invention relates to a packing device comprising a plurality of packing elements (2) each of which contains at least one product unit (3) which are connected to each other and are placed in the same external package, a plurality of security elements (9) belonging to said packing elements or connected thereto and disposed in such a way that it is possible to jointly distribute at least one packing element (2) and at least one security element (9).
Abstract:
The invention concerns a security paper comprising at least two plies of paper, wherein at least one intermediate layer arranged between the two plies of paper comprises at least one element providing the paper with high double folding resistance, such as defined by the NF ISO 5626 standard, the two plies and said intermediate layer being closely assembled. The invention also concerns a method for making said paper whereby the intermediate layer is deposited by spraying.
