Plus précisément, l'invention se rapporte à un dispositif de sécurité destiné à permettre la surveillance d'une accessibilité à un objet, caractérisé en ce qu'il comprend :
- au moins une enveloppe souple constituée d'un tissu réalisé à partir d'au moins un fil conducteur souple entouré d'une gaine isolante souple, ladite enveloppe souple adoptant une forme de poche définissant une partie creuse apte à contenir ledit objet, et au moins une ouverture que ledit objet est apte à traverser pour être logé dans ladite partie creuse,

- at least one flexible envelope consisting of a fabric made from at least one flexible conductive wire surrounded by a flexible insulating sheath, said flexible envelope adopting a pocket shape defining a hollow portion adapted to contain said object, and at least an opening that said object is able to pass through to be housed in said hollow portion,
- means for closing said opening comprising at least first and second conductive tracks, at least one of which is provided with at least one self-adhesive conductive layer, said first and second conductive tracks constituting the two electrodes, anode and cathode , of a capacity, and being able to adopt at least the two following distinct positions:

Le dispositif selon l'invention permet de réduire de manière très importante les connexions électriques et propose une enveloppe simple qui peut avantageusement être réalisée au moyen d'un fil unique, avec très peu de raccords électriques, de type soudure ou connecteur électrique ou analogue, voire un simple raccord électrique du tissu aux moyens de contrôle. L'objet dont on souhaite surveiller l'accessibilité est apte à être enfermé à l'intérieur de l'enveloppe souple en forme de poche, qui épousera plus ou moins les contours dudit objet grâce à sa souplesse, afin de réduire au minimum l'encombrement du dispositif par rapport au volume de l'objet. Une fois l'enveloppe fermée grâce aux moyens de fermeture tels que définis, l'objet à l'intérieur est placé sous surveillance par les moyens de contrôle, et toute ouverture de l'enveloppe, soit par l'ouverture prévue pour l'insertion et le retrait de l'objet, soit par effraction par exemple par déchirure ou entaille de l'enveloppe, sera détectée par les moyens de contrôle spécifiés. Une fois que deux pistes conductrices en vis-à-vis sont en contact l'une avec l'autre via la couche conductrice autocollante, par exemple respectivement les première et deuxième pistes, et/ou les troisième et quatrième pistes, deux pistes en contact produisent un effet capacitif qui permet de repérer une ouverture ou une fermeture respectivement par séparation et contact de ces deux pistes conductrices qui modifie la capacité électrique mesurée entre les pistes en contact. Par accessibilité à un objet, on entend ici le franchissement de la barrière que constitue l'enveloppe de protection enfermant l'objet à l'intérieur de celle-ci, et constituant ainsi, une enceinte fermée autour de l'objet, par les diverses voies détaillées plus haut. Les moyens de fermeture permettent une réutilisation ultérieure du dispositif de sécurité après une première utilisation, en ce que les pistes conductrices peuvent adopter plusieurs fois la position active ou inactive, par collages et décollages successifs.The device according to the invention makes it possible to reduce very significantly the electrical connections and proposes a simple envelope which can advantageously be made by means of a single wire, with very few electrical connections, of the welding type or electrical connector or the like, even a simple electrical connection of the fabric to the control means. The object whose accessibility is to be monitored is capable of being enclosed within the flexible pouch-shaped envelope, which will more or less conform to the contours of said object by virtue of its flexibility, in order to reduce to a minimum the size of the device relative to the volume of the object. Once the envelope closed thanks to the closing means as defined, the object inside is placed under surveillance by the control means, and any opening of the envelope, or by the opening provided for insertion and removal of the object, either by breaking, for example by tearing or notching the envelope, will be detected by the specified control means. Once two conductive tracks vis-à-vis are in contact with each other via the conductive adhesive layer, for example respectively the first and second tracks, and / or the third and fourth tracks, two tracks in contact with each other. produce a capacitive effect which makes it possible to locate an opening or a closure respectively by separating and contacting these two conducting tracks which modifies the electrical capacitance measured between the tracks in contact. Accessibility to an object here means crossing the barrier constituted by the protective envelope enclosing the object inside the latter, and thus constituting, a closed enclosure around the object, by the various detailed routes above. The closure means allow a subsequent reuse of the safety device after a first use, in that the conductive tracks can adopt several times the active or inactive position, by successive collages and takeoffs.

Il y a lieu de noter que le dispositif selon l'invention peut comprendre un dispositif de destruction ou de neutralisation du contenu intégré dans l'enveloppe selon tout moyen connu, notamment par jet d'encre indélébile, par exemple connecté à la base et activé à partir de celle-ci, ou autonome et activé automatiquement par les moyens de contrôle intégrés dans l'enveloppe souple 1, dès la première tentative d'ouverture, suivant un seuil de déclenchement défini par une mesure spécifique de l'effet capacitif, ou de percement de l'enveloppe.It should be noted that the device according to the invention may comprise a device for destroying or neutralizing the content integrated in the envelope according to any known means, in particular by indelible ink jet, for example connected to the base and activated from it, or autonomous and automatically activated by the control means integrated in the
Les enveloppes souples peuvent avoir des dimensions variées, par exemple d'un format A5 jusqu'à plusieurs mètres carrés, ce qui permet de placer à l'intérieur d'une enveloppe des équipements électroniques qui réagiront à l'ouverture intempestive ou au percement de l'enveloppe, en se plaçant hors circuit, de manière à rendre leur utilisation future problématique, et en tout état de cause nécessitant l'application d'un correctif pour les rendre à nouveau fonctionnels. Les dispositifs de sécurité selon l'invention seront avantageusement réutilisables comme expliqué plus haut, dans le cadre d'une utilisation normale, dans la mesure où les enveloppes souples n'auront pas été endommagées, par exemple par une coupure du tissu réalisé à partir d'un fil conducteur.The flexible envelopes can have various dimensions, for example of a size A5 up to several square meters, which makes it possible to place inside an envelope of the electronic equipment which will react to the untimely opening or to the drilling of the envelope, setting itself off, so as to make their future use problematic, and in any case requiring the application of a patch to make them functional again. The security devices according to the invention will advantageously be reusable as explained above, in the context of normal use, insofar as the flexible envelopes have not been damaged, for example by cutting the fabric made from 'a common thread.
