A la figure 1, un dispositif portable électronique conforme à l'art antérieur, comprend un module de communication à travers le corps (de type eGo) 2 ; Le module comporte une surface de contact 3 pouvant contacter ou non électriquement la peau d'un porteur ; Le dispositif comprend également une base 4 (ou boitier de base) comportant le module 2 ; Il comprend aussi des moyens de solidarisation 5A, 5B du dispositif à une partie du corps du porteur, au contact de la peau ; Il comprend aussi des moyens de fixation 6A, 6B d'un accessoire personnel 7 ou d'un boîtier de montre 8 sur le dispositif. Le dispositif comprend une montre 8 de l'utilisateur comme accessoire. La montre se fixe sur la base 4 par l'intermédiaire des attaches de montre 6A, 6B. Le dispositif comprend des moyens de détection d'une solidarisation et désolidarisation au porteur (non représentés entièrement) . Ces moyens peuvent comprendre, par exemple, un circuit conducteur 16 s' étendant de la base 4, 14 vers les bras ou sous-parties 5A, 5B du bracelet et comportant aux extrémités des plaques de condensateur 17, 18. In Figure 1, an electronic portable device according to the prior art, comprises a communication module through the body (type eGo) 2; The module comprises a contact surface 3 that can contact or not electrically the skin of a wearer; The device also comprises a base 4 (or base box) comprising the module 2; It also comprises means of securing 5A, 5B of the device to a part of the body of the wearer, in contact with the skin; It also comprises fastening means 6A, 6B of a personal accessory 7 or a watch case 8 on the device. The device comprises a watch 8 of the user as an accessory. The watch is fixed on the base 4 via the watch clips 6A, 6B. The device comprises means for detecting a fastening and disconnection to the wearer (not shown entirely). These means can comprise, for example, a conductive circuit 16 extending from the base 4, 14 to the arms or sub-parts 5A, 5B of the bracelet and having at the ends of the capacitor plates 17, 18.
En position de bracelet bouclé, les plaques de condensateur se trouvent en regard l'une de l'autre fermant ainsi le circuit électrique 16. Le dispositif comprend également un circuit de détection de l'état bouclé du bracelet qui est une fonction de l'écartement des plaques capacitives.

Le dispositif est configuré de manière à effectuer une transaction après authentification et solidarisation de préférence dans un délai prédéterminé et/ou avant détection d'une désolidarisation . Ensuite, l'utilisateur enlève son bracelet, ce qui provoque un éloignement des capacités 17, 18 l'une de l'autre ; cet état d' éloignement est détecté par le circuit de détection qui en informe le microcontrôleur. Ensuite, le microcontrôleur désactive ou inhibe toute autorisation de transaction par communication à travers le corps ou corporelle. In the looped bracelet position, the capacitor plates are opposite each other thus closing the electrical circuit 16. The device also comprises a circuit for detecting the looped state of the bracelet which is a function of the spacing capacitive plates. This circuit can be in the base and can supply information to an input of a microcontroller. The device is configured to perform a transaction after authentication and attachment preferably within a predetermined time and / or before detaching a detachment. Then, the user removes his bracelet, which causes a distance of the capabilities 17, 18 of one another; this state of separation is detected by the detection circuit which informs the microcontroller. Then, the microcontroller disables or inhibits any transaction authorization by communication through the body or body.
A la figure 2A est illustré un système de fermeture /ouverture 20 conforme à un premier mode de réalisation l'invention et comprenant ou formant un interrupteur électrique. In Figure 2A is illustrated a closing / opening system 20 according to a first embodiment of the invention and comprising or forming an electrical switch.
Le système de fermeture/ouverture selon l'invention comprend un fermoir 20 pour différents moyens d'attache ou de liaison notamment pour un bracelet de montre, une ceinture, une sangle porte-bagage ou équivalents. Selon l'invention ces systèmes réalisent également une fonction électrique. The closure / opening system according to the invention comprises a clasp 20 for various fastening or connecting means, in particular for a watch strap, a belt, a luggage strap or the like. According to the invention these systems also perform an electrical function.
De préférence, ce système est fixé sur le corps d'un porteur mais il peut être utilisé pour fixer ou attacher tout objet. Par exemple, des liens peuvent être fixés sur un mur de manière à y attacher un autre objet avec sécurité. En cas de détachement non autorisé du lien, une alarme ou autre action peut être déclenchée telle une inhibition d'une fonction de 1 ' obj et . Selon une caractéristique des modes de réalisation de l'invention, ces systèmes comportent ou forment un interrupteur à contacts électriques agencé sur le fermoir. Ce type d'interrupteur à contacts électriques est choisi avantageusement pour la simplicité de mise en œuvre. Preferably, this system is attached to the body of a wearer but it can be used to fix or attach any object. For example, links may be attached to a wall so that another object can be securely attached. In case of unauthorized detachment of the link, an alarm or other action may be triggered such as an inhibition of a function of the obj and. According to one characteristic of the embodiments of the invention, these systems comprise or form a switch with electrical contacts arranged on the clasp. This type of switch with electrical contacts is advantageously chosen for simplicity of implementation.
Dans les exemples, l'état ouvert et fermé de l'interrupteur électrique s'établit respectivement lors de l'ouverture et fermeture du fermoir. Toutefois cela pourrait être l'inverse selon la position ou agencement des contacts électriques. In the examples, the open and closed state of the electric switch is established respectively when opening and closing the clasp. However this could be the opposite depending on the position or arrangement of the electrical contacts.
Dans l'exemple, le système comprend ici un fermoir 20 du type à boucle ardillon comportant une boucle 21A, un ardillon ou pointe pivotante 22A autour d'un axe de rotation 23 fixé sur la boucle 21A. Toutefois, d'autres types de fermoir peuvent convenir tel que par exemple une boucle papillon, une boucle déployante, etc. In the example, the system here comprises a clasp 20 of the buckle type comprising a loop 21A, a barb or pivot point 22A about an axis of rotation 23 fixed on the loop 21A. However, other types of clasp may be suitable such as for example a butterfly buckle, a folding clasp, etc.
En ce qui concerne le fermoir a boucle à ardillon de l'exemple, les contacts électriques 21B, 22B de l'interrupteur se trouvent respectivement sur la boucle et l'extrémité libre de l'ardillon; Ils correspondent ici à des zones de contact d'une extrémité de l'ardillon avec sensiblement une zone centrale 21B la boucle. Ces zones de contact électrique 21B, 22B peuvent recevoir un traitement spécifique, au moins localisé, anticorrosion et/ou revêtement d'un bon conducteur électrique, tel du cuivre, or... As regards the buckle clasp of the example, the electrical contacts 21B, 22B of the switch are respectively on the loop and the free end of the barb; They correspond here to contact zones of one end of the barb with substantially a central zone 21B the loop. These electrical contact zones 21B, 22B may receive a specific treatment, at least localized, anticorrosion and / or coating of a good electrical conductor, such as copper, gold, etc.
L'ardillon est ici dans l'exemple, isolé électriquement de la boucle. L'isolation est réalisée en utilisant un axe de rotation de l'ardillon 23 en matière isolante, par exemple un tube plastique. Alternativement, l'ardillon 22A lui même peut être en matière isolante, du moins au niveau d'un œillet 24 (ou palier d'axe) de l'ardillon alors qu'il peut comprendre (au moins en surface un revêtement conducteur destiné à contacter la boucle et s'étendant jusqu'à la périphérie de l'oeiller 24 d' ardillon . The pin is here in the example, electrically isolated from the loop. The insulation is made using an axis of rotation of the barb 23 of insulating material, for example a plastic tube. Alternatively, the barb 22A itself may be of insulating material, at least at an eyelet 24 (or shaft bearing) of the barb, whereas it may comprise (at least on the surface a conductive coating for contact the loop and extending to the periphery of the pin eye.
L'œillet 24 de l'ardillon et la boucle 21A sont respectivement reliés à une première 25 et seconde piste (ou ruban) 26 électriquement conductrices s'étendant ou destinées à s'étendre le long d'un bracelet ou branche de bracelet jusqu'à un boitier électronique d'un dispositif électronique 27 (fig. 3) . The eyelet 24 of the barb and the loop 21A are respectively connected to a first 25 and second electrically conductive track (or ribbon) 26 extending or intended to extend along a bracelet or bracelet branch until to an electronic box of an electronic device 27 (FIG 3).
Les pistes (ou rubans conducteur flexible 25, 26) sont respectivement au contact électrique, notamment par frottement, avec un bord de la boucle et une surface périphérique de l'œillet 24.  The tracks (or flexible conductor strips 25, 26) are respectively in electrical contact, in particular by friction, with an edge of the loop and a peripheral surface of the eyelet 24.
Les rubans ou (fils conducteurs) sont de préférence enrobés de matière isolante et le cas échéant dénudés à leur extrémités pour connexion électrique.  The ribbons or (conductive wires) are preferably coated with insulating material and, where appropriate, stripped at their ends for electrical connection.
L'ensemble (boucle à ardillon 20, pistes 25, 26, boitier ou composant électronique 28) peut être conditionné, enveloppé en tout ou partie dans une branche de bracelet tel qu' illustré à la figure 3.  The assembly (pin buckle 20, tracks 25, 26, housing or electronic component 28) may be conditioned, wrapped in whole or part in a bracelet branch as illustrated in FIG.
A la figure 3 est illustré le système de fermeture/ouverture avec fonction interrupteur à contacts électriques comportant l'ensemble ci-dessus. L'ensemble (20, 25, 26, 28) est avantageusement conditionné dans une seule branche 27 de bracelet pour simplifier la fabrication. In Figure 3 is shown the closing / opening system with switch function with electrical contacts comprising the above assembly. The assembly (20, 25, 26, 28) is advantageously packaged in a single branch 27 of a bracelet to simplify manufacture.
Le conditionnement de la branche 27 (figure 4) peut comporter une enveloppe en cuir ou en matière plastique formée d'une bande 30 repliée sur elle-même à plat avec les extrémités venant en butée l'une contre l'autre au milieu du verso de la bande. La branche 27 comporte ici deux orifices ou fentes 32 d'un côté pour permettre la sortie des rubans conducteurs (les rubans peuvent être isolés électriquement au moins au voisinage des axes de rotation) . De l'autre côté opposé, la branche comporte ici un orifice 31 pour permettre la sortie de l'ardillon sensiblement de manière classique. La branche comporte un logement cylindrique 23A pour la réception d'axe de rotation à chaque extrémité. Selon une caractéristique, les deux premier et second contacts électriques 21B, 22B sont reliés à un boîtier électronique 28 via deux pistes (ou ruban) électriquement conductrices 25, 26 s 'étendant respectivement le long d'une même partie de lien (branche) tel qu'un bracelet, sangle, ceinture, à partir du premier et le second contacts. The conditioning of the branch 27 (FIG. 4) may comprise a leather or plastic envelope formed of a band folded on itself flat with the ends abutting against each other in the middle of the back. of the bandaged. The branch 27 here comprises two orifices or slots 32 on one side to allow the output of the conductive ribbons (the ribbons may be electrically insulated at least in the vicinity of the axes of rotation). On the other opposite side, the branch here comprises an orifice 31 to allow the exit of the barb substantially in a conventional manner. The branch comprises a cylindrical housing 23A for receiving the axis of rotation at each end. According to one characteristic, the two first and second electrical contacts 21B, 22B are connected to an electronic box 28 via two electrically conductive tracks (or ribbon) 25, 26 extending respectively along the same link part (branch) as a bracelet, strap, belt, from the first and second contacts.
Le boîtier électronique peut comporter une fonction d'inhibition de fonctionnement en cas d'ouverture du circuit interrupteur sans autorisation (notamment authentification) et tout autre fonction électronique et/ou de communication, paiement, identification, etc. The electronic box may include a function of inhibition of operation in case of opening of the switch circuit without authorization (including authentication) and any other electronic function and / or communication, payment, identification, etc..
Dans l'exemple, les rubans conducteurs sont agencés et collés de préférence sur une face intérieure et le long de la bande 30 en faisant sortir les rubans du côté du composant 28. La boucle à ardillon ou au moins les axes de rotation (axes de bracelet de montre à pistons) et ardillon peuvent être installés sur la bande avant repliement et collage de la bande sur elle même. In the example, the conductive ribbons are arranged and bonded preferably on an inner face and along the strip 30 by pulling the ribbons on the side of the component 28. The pin buckle or at least the axes of rotation (axes of pistons wrist watch) and barb can be installed on the band before folding and sticking the band on itself.
Ensuite, les extrémités libres des pistes conductrices 26, 25 opposées à la boucle, sont reliés au boîtier 28 ou composant électronique par collage ou par un procédé hybride classique de fabrication de plaque de circuit imprimé (PCB) . Le système de la figure 3 (20, 25 - 28, 30) en l'état, peut former ou être intégré dans un dispositif portable électronique 1 comprenant une variante de système de fermeture/ouverture du bracelet et une branche de bracelet ou sangle pour le maintien ou fixation du dispositif sur tout objet, partie ou spécifiquement autour d'une partie d'un porteur tel un poignet . Then, the free ends of the conductive tracks 26, 25 opposite to the loop, are connected to the housing 28 or electronic component by gluing or by a conventional hybrid method of manufacturing a printed circuit board (PCB). The system of Figure 3 (20, 25 - 28, 30) as it is, can form or to be integrated into an electronic portable device 1 comprising a variant of a closure / opening system of the bracelet and a bracelet or strap branch for holding or fixing the device on any object, part or specifically around a portion of a wearer such as a wrist .
Dans l'exemple, illustré aux figures 5, 6, le composant 28 et les portions de pistes 25, 26 situées proches du composant, peuvent être intégrés dans un boîtier 32 de montre 1B, 1C notamment en plastique, avec écran 29, de manière à constituer un dispositif électronique portable doté du système de fermeture / ouverture du type à interrupteur à contacts électriques de l'invention. In the example, illustrated in FIGS. 5, 6, the component 28 and the track portions 25, 26 located near the component, can be integrated in a watch case 1B, 1C especially made of plastic, with screen 29, so that to constitute a portable electronic device with the closing / opening system of the type with electrical contact switch of the invention.
Sur les figures 2B et 2C, on représente un axe d'ardillon modifié 23 résultant d'une adaptation d'un axe courant 37 de montre pour permettre une fabrication alternative de boucle à ardillon FIGS. 2B and 2C show a modified pin axis 23 resulting from an adaptation of a current clock axis 37 to allow alternative manufacture of pin buckle
La figure 2C représente l'axe modifié 23 enfilé dans l'œillet 24 de l'ardillon 22A en vue de profil et la figure 2B représente une coupe selon A-A.  Figure 2C shows the modified axis 23 threaded into the eyelet 24 of the barb 22A in profile and Figure 2B shows a section along A-A.
L'axe 23 comporte un premier manchon isolant 33 s' étendant autour de l'axe courant 37 sur une majorité de la longueur de 1 ' axe .  The axis 23 comprises a first insulating sleeve 33 extending around the current axis 37 over a majority of the length of the axis.
L'axe d'ardillon modifé 23 peut comporte aussi un autre manchon conducteur 34 sur la longueur restante pour homogéniser le diamètre de l'axe 23. The modified pin axis 23 may also include another conductive sleeve 34 over the remaining length to homogenize the diameter of the axis 23.
L'axe 23 comporte aussi un manchon conducteur électriquement 35 collé ou fixé sensiblement au milieu de l'axe 37 sur le manchon isolant 33 de manière à rester en contact électrique avec l'ardillon qui comporte également ou est constitué d'une matière conductrice électriquement. Le manchon conducteur central 35 est relié électriquement au ruban conducteur 25 qui peut faire un tour au moins partiel autour de l'axe 23 et /ou être fixé à lui par une colle conductrice . The axis 23 also comprises an electrically conductive sleeve 35 bonded or fixed substantially in the middle of the axis 37 on the insulating sleeve 33 so as to remain in electrical contact with the pin which also comprises or consists of an electrically conductive material . The central conductive sleeve 35 is electrically connected to the conductive ribbon 25 which can rotate at least partially around the axis 23 and / or be fixed to it by a conductive adhesive.
Le manchon conducteur latéral 34 est relié électriquement au ruban conducteur 26 qui peut aussi faire un tour au moins partiel autour du manchon latéral et /ou y être fixé à lui par de la colle conductrice. Ainsi, cet axe adapté 23 pour la boucle à ardillon 20, permet de modifier uniquement l'axe de la boucle à ardillon qui peut s'adapter sur toute boucle à ardillon classique sans rien changer au montage de la boucle sur une branche de bracelet. L'axe de montre comporte de manière classique un ressort 36 central interne appuyant sur des pistons mobiles latéraux 37P. The lateral conductive sleeve 34 is electrically connected to the conductive strip 26 which can also rotate at least partially around the side sleeve and / or be attached to it by conductive adhesive. Thus, this axis 23 adapted for the pin buckle 20, can only change the axis of the pin buckle that can fit on any classic buckle loop without changing anything at the mounting of the loop on a bracelet branch. The watch axle conventionally comprises an internal central spring 36 pressing on lateral movable pistons 37P.
La figure 5 illustre le système complet de l'invention 1 tel qu' intégré dans une montre 1B avec un boîtier 32 de montre enveloppant et s' étendant jusqu'au bracelet 27. Ainsi, les rubans conducteurs peuvent passer directement de la branche de bracelet 27 dans le boîtier à partir du bracelet sans apparaître à l'extérieur. FIG. 5 illustrates the complete system of the invention 1 as integrated in a watch 1B with a wrap-around watch case 32 and extending to the strap 27. Thus, the conductive ribbons can pass directly from the bracelet branch 27 in the case from the bracelet without appearing outside.
Le passage des rubans conducteurs électriquement vers le boitier peut être similaire au système décrit précédemment à la figure 2B avec l'axe de rotation 23. On peut également recourir à des systèmes à bille venant en appui sur des bossages conducteurs 47 (ou des inserts conducteurs) logés sur une extrémité arrondie du bracelet 27 et soudé aux rubans conducteurs (ou en contact avec eux) comme illustré à la figure 5B. The passage of electrically conductive ribbons to the housing may be similar to the system described above in FIG. 2B with the axis of rotation 23. It is also possible to resort to ball systems bearing on conducting bosses 47 (or conductive inserts). ) housed on a rounded end of the bracelet 27 and welded to the conductive ribbons (or in contact with them) as shown in Figure 5B.
Sur cette figure 5B, une extrémité du bracelet (côté boîtier de montre) comporte un bossage arrondi conducteur électriquement 47 serti sur l'extrémité de la branche 27 et maintenu par des crans 48 enfoncés dans la matière du bracelet par exemple au cours d'un assemblage tel un sertissage. Ce bossage comporte une partie externe arrondie, comme une came, destinée à venir au contact d'une bille ou autre pièce équivalente 46 du boîtier de montre. Le bossage comporte une partie concave sensiblement à l'intérieur pour recevoir l'extrémité du bracelet et le ruban dénudé en partie, le ruban étant pris en sandwich entre le bossage et l'extrémité du bracelet . In this FIG. 5B, one end of the bracelet (watchcase side) has an electrically conductive rounded boss 47 crimped onto the end of the branch 27 and maintained by notches 48 embedded in the material of the bracelet for example during an assembly such a crimping. This boss has a rounded outer portion, such as a cam, intended to come into contact with a ball or other equivalent piece 46 of the watch case. The boss has a concave portion substantially on the inside to receive the end of the bracelet and partially stripped ribbon, the ribbon being sandwiched between the boss and the end of the bracelet.
La surface arrondie du bossage 47 est en contact avec un système à contact électrique à cylindre 46 (ou équivalent notamment à bille) qui coulisse dans un logement adapté du boîtier de montre 38 en étant pressé par un ressort contre le bossage 47. Le ruban 25 sort de la branche 27 par l'orifice 32 et son extrémité dénudée vient au contact électrique du bossage 47 au niveau de sa zone concave interne entre l'extrémité du bracelet et lui-même. Le ressort peut être ensuite connecté à un composant ou circuit électronique 28 du boîtier . The rounded surface of the boss 47 is in contact with an electrical contact system with a cylinder 46 (or equivalent, in particular with a ball), which slides in a suitable housing of the watch case 38 by being pressed by a spring against the boss 47. leaving the branch 27 through the orifice 32 and its stripped end comes into electrical contact with the boss 47 at its inner concave zone between the end of the bracelet and itself. The spring can then be connected to an electronic component or circuit 28 of the housing.
A la figure 5C, est illustré un autre exemple de raccordement électrique des pistes du bracelet 25A, 26A à des contacts électriques dans le boitier de montre de la figure 5. In FIG. 5C is illustrated another example of electrical connection of the tracks of the bracelet 25A, 26A to electrical contacts in the watch case of FIG. 5.
L'axe 23B de fixation de la branche de bracelet au boîtier est sensiblement différent de celui de la figure 2B. La partie centrale est isolante électriquement et est recouverte de deux manchons conducteurs électriquement 35A et 35B aux extrémités avec un manchon 33 isolant électriquement entre les deux.  The axis 23B for attaching the bracelet branch to the housing is substantially different from that of FIG. 2B. The central portion is electrically insulating and is covered with two electrically conductive sleeves 35A and 35B at the ends with a sleeve 33 electrically insulating between the two.
Les extrémités de l'axe sont fixés au boîtier par deux vis latérales 46 ou équivalent.  The ends of the axis are fixed to the housing by two side screws 46 or equivalent.
Les pistes ou rubans 25A, 26A, 25B, 26B peuvent être par exemple surmoulées de matériau plastique 27 ou 32 ou de résine. L'extrémité des rubans conducteurs 25A et 25B est dénudée et mis en contact par frottement avec les manchons conducteurs 35A et 35B. Tandis que les rubans conducteurs 25A et 25B peuvent être connectés aux manchons conducteurs 35A, 35B par colle conductrice ou par frottement. The tracks or tapes 25A, 26A, 25B, 26B may for example be overmolded with plastic material 27 or 32 or resin. The end of the conductor strips 25A and 25B is stripped and frictionally contacted with the conductive sleeves 35A and 35B. While the conductive strips 25A and 25B may be connected to the conductive sleeves 35A, 35B by conductive glue or by friction.
Ainsi, les rubans du bracelet connectent les rubans du boîtier par l'intermédiaire des manchons 35A et 35B. Thus, the ribbons of the bracelet connect the ribbons of the housing via the sleeves 35A and 35B.
A la figure 6, l'ensemble de la figure 3 ou au moins des rubans conducteurs 25, 26 peuvent être intégrés dans un bracelet 27 de montre au cours d'une opération de surmoulage notament plastique du boîtier de montre 32 et des branches 27. Ainsi, il n'y a pas de jonction et de possible exposition à l'extérieur des rubans conducteurs à l'interface du bracelet avec le boîtier de montre. Le boîtier de montre et les branches peuvent être également réalisée par impresssion 3D sur les rubans.  In FIG. 6, the assembly of FIG. 3 or at least conducting ribbons 25, 26 can be integrated in a watch strap 27 during a plastic molding operation of the watch case 32 and branches 27. Thus, there is no junction and possible exposure outside the conductive ribbons at the interface of the bracelet with the watch case. The watch case and the branches can also be made by 3D printing on the ribbons.
A la figure 7A et 8A, est illustré un second mode de réalisation du système conforme à l'invention respectivement en position ouvert et fermé. In FIGS. 7A and 8A, there is illustrated a second embodiment of the system according to the invention respectively in open and closed position.
Le système 1D est dans l'exemple également une montre comme précédemment mais avec un fermoir 38 à boucle déployante. Il comprend un composant électronique 28 s' étendant lelong d'au moins une branche de bracelet 27. La boucle déployante comporte deux parties métalliques 39, 40 courbées et articulées entre elles par une articulation 41 et fixée chacune à une branche respective 27 du bracelet par une autre articulation 42, 43. The 1D system is in the example also a watch as before but with a clasp 38 with folding clasp. It comprises an electronic component 28 extending along at least one bracelet branch 27. The folding clasp comprises two metal parts 39, 40 curved and hinged together by a hinge 41 and each fixed to a respective branch 27 of the bracelet by another articulation 42, 43.
Selon ce mode de réalisation, deux contacts électriques 22A, 22B de l'interrupteur (fig.7B) sont situés sur une partie 45 du bracelet proche de l'articulation 43 tandis qu'un autre contact électrique 44, destiné à relier ensemble les deux contacts électriques 22A et 22B, est situé sur une autre partie opposée du bracelet 44 proche de l'articulation 42 (fig.7A) . According to this embodiment, two electrical contacts 22A, 22B of the switch (FIG. 7B) are located on a portion 45 of the bracelet near the joint 43 while another electrical contact 44, intended to connect the two together 22A and 22B electrical contacts, is located on another opposite portion of the bracelet 44 near the joint 42 (Fig.7A).
Lorsque le bracelet est fermé figures 8A, 8B, la partie de liaison 22C se rapproche des deux contacts électriques 22A, 22B pour les contacter ensemble électriquement au cours du verrouillage du bracelet et fermer ainsi l'interrupteur (22A, 22B, 22C) pour passage de courant électrique (i) . Les rubans conducteurs de ce second mode peuvent être réalisés sensiblement comme précédemment selon le premier mode à la différence que la boucle 21A est remplacée par une des parties courbées 39, 40 et l'axe 43 porte les deux contacts électriques 22A, 22B de préférence en étant isolé de l'axe avec un manchon isolant 45. Chaque ruban 25 et 26 contacte électriquement un contact électrique correspondant (pouvant être de révolution autour du manchon isolant.  When the bracelet is closed, FIGS. 8A, 8B, the connecting portion 22C approaches the two electrical contacts 22A, 22B to contact them electrically together during the locking of the bracelet and thus close the switch (22A, 22B, 22C) for passage of electric current (i). The conductive ribbons of this second mode can be made substantially as before according to the first embodiment, with the difference that the loop 21A is replaced by one of the curved parts 39, 40 and the axis 43 carries the two electrical contacts 22A, 22B preferably in being isolated from the axis with an insulating sleeve 45. Each strip 25 and 26 electrically contacts a corresponding electrical contact (which may be of revolution around the insulating sleeve.
Le contact électrique 22C peut être un clip conducteur ou simplement une surface conductrice disposée sur l'axe conducteur éventuellement sur un manchon isolant électriquement 44 qui vient contacter les deux contacts électriques 22A, 22B quand le bracelet est fermé. Dans le cas où les branches 27 sont en métal notamment en maillons métalliques (contrairement aux modes précédents), et séparées par un fermoir à boucle déployante, l'invention peut prévoir une séparation isolante entre les deux branches au niveau du fermoir (par exemple, en intégrant un axe isolant, ou un maillon isolant) . Les rubans fils conducteurs 25, 26 peuvent s'étendre lelong d'une branche 27 jusqu'au fermoir 38 en étant recouverts ou pris en sand itch entre deux rubans isolants . Le cas échéant au moins une des branches peut être adaptée pour ménager une rainure (non représenée) sur sa surface interne tout le long de la branche afin d'y recevoir une nappe de deux fils isolés ou rubans conducteurs enrobés d'isolant. The electrical contact 22C may be a conductive clip or simply a conductive surface disposed on the conductive axis optionally on an electrically insulating sleeve 44 which comes into contact with the two electrical contacts 22A, 22B when the bracelet is closed. In the case where the branches 27 are made of metal, especially in metallic links (unlike the previous modes), and separated by a clasp with folding clasp, the invention can provide an insulating separation between the two branches at the clasp (for example, by integrating an insulating axis, or an insulating link). The conductive son ribbons 25, 26 can extend along a branch 27 to the clasp 38 by being covered or sandwiched between two insulating tapes. Where appropriate at least one of the branches may be adapted to provide a groove (not shown) on its inner surface all along the branch to receive a sheet of two insulated wires or conductive strips coated with insulation.
A la figure 9 est illustrée une portion de branche 27. La branche 27 est composée de deux sous-branches longitudinales formées chacune de maillons 27A et 27B articulés autour d'axes 37. Les maillons de chaque sous-branche 27A et 27B sont isolés entre eux par des pièces de jonction intermédiaires 33 et axes 37 isolants électriquement. Le contact électrique entre des maillons d'une sous-branche peut s'effectuer via des manchons conducteurs 35 sur chaque axe isolant 37. Les deux rubans conducteurs 25-26 sont donc remplacés par les branches 27A et 27B. L'ajustement entre les pièces peut être suffisant pour créer le contact électrique entre les maillons 27A ou 27B. Les manchons conducteurs électriquement 35 et manchon intermédiaire isolant 33B peuvent le cas échéant être supprimés . In FIG. 9 is illustrated a branch portion 27. The branch 27 is composed of two longitudinal sub-branches each formed of links 27A and 27B articulated about axes 37. The links of each sub-branch 27A and 27B are isolated between them by intermediate connecting pieces 33 and electrically insulating pins 37. The electrical contact between links of a sub-branch can be via conductive sleeves 35 on each insulating axis 37. The two conductive strips 25-26 are replaced by the branches 27A and 27B. The fit between the pieces may be sufficient to create the electrical contact between the links 27A or 27B. The electrically conductive sleeves 35 and insulating intermediate sleeve 33B may be omitted if necessary.
Le dispositif 1, 1B, 1C, 1D peut être celui de la figure 1 avec des adaptations selon l'invention. The device 1, 1B, 1C, 1D can be that of Figure 1 with adaptations according to the invention.
Selon une caractéristique, le dispositif 1B, 1C, 1D portable électronique peut comprendre dans le boîtier, un module de communication à travers le corps . Ce module comporte de préférence une surface de contact destinée à contacter électriquement la peau d'un porteur ou comporte une électrode pour induire un champ électrique sur la peau. According to one characteristic, the device 1B, 1C, 1D electronic portable can comprise in the housing, a communication module through the body. This module preferably comprises a contact surface intended to electrically contact the skin of a wearer or comprises an electrode for inducing an electric field on the skin.
Selon une caractéristique, le dispositif portable électronique est configuré de manière à permettre au moins un fonctionnement ou au moins une opération après authentification et fermeture du circuit et/ou interdire au moins un fonctionnement ou opération suite à une ouverture du circuit électrique. According to one characteristic, the portable electronic device is configured to allow at least one operation or at least one operation after authentication and closure of the circuit and / or to prohibit the less operation or operation following an opening of the electrical circuit.
Par exemple, le dispositif 1B, 1C, 1D peut aussi déclencher une alarme si un objet est attaché ou maintenu avec le système de fermeture / ouverture de l'invention. En particulier, l'ouverture de l'interrupteur du circuit peut rompre un état haut de tension qui est détecté et provoque le déclenchement d'une opération quelconque. For example, the device 1B, 1C, 1D can also trigger an alarm if an object is attached or held with the closing / opening system of the invention. In particular, the opening of the switch of the circuit can break a high voltage state which is detected and causes the triggering of any operation.
Alternativement, une information d' authentification peut être stockée dans une mémoire volatile après la fermeture du circuit et interrupteur à contact. Cette information permet d'effectuer une transaction car sa présence est vérifiée dans la mémoire volatile avant de valider une transaction. Alternatively, authentication information may be stored in a volatile memory after closing the circuit and contact switch. This information makes it possible to perform a transaction because its presence is checked in the volatile memory before validating a transaction.
Si l'interrupteur 20, 38 est ouvert, par exemple parce que le dispositif a été arraché du porteur ou parce qu'un objet était maintenu avec le système de fermoir de l'invention à un endroit quelconque sécurisé avec le système de l'invention, alors, la mémoire n'est plus alimenté et l'information d' authentification est perdue. If the switch 20, 38 is open, for example because the device was torn off the carrier or because an object was held with the clasp system of the invention at any point secured with the system of the invention then, the memory is no longer powered and the authentication information is lost.
L'information d' authentification peut être de toute sorte, et saisie de toute manière. Elle peut être une empreinte digitale sisie avec un capteur d'empreinte, une voix, un ou des sons audio saisis par microphone, une signature saisie sur un pavé sensitif, un code PIN, un iris de l'œil, etc. The authentication information can be of any kind, and entered anyway. It can be a fingerprint with a fingerprint sensor, a voice, one or more audio sounds entered by microphone, a signature entered on a touchpad, a PIN code, an iris of the eye, etc.
Ainsi, l'invention permet d'économiser de l'énergie de batterie. L'ouverture de l'invention qui peut correspondre à l'état de repos de l'oject non porté ne consomme aucune énergie car le circuit de courant est ouvert. La fermeture de l'invention qui peut correspondre à un état actif de l'objet attaché/porté ne consomme qu'un très faible courrant de l'ordre du micro ampère. Ce courant est inférieure au courant de stand by du produit et ne modifie pas significativement l'autonomie de celui ci; Thus, the invention saves battery power. The opening of the invention which can correspond to the state of rest of the unworn oject consumes no energy because the current circuit is open. The closure of the invention which may correspond to an active state of the attached / worn object consumes only a very small current of the order of the micro ampere. This current is lower than the current stand by the product and does not significantly alter the autonomy of it;
Les contact de commutation 21B, 22B sont fiables. L'emplacement des commutateurs sur une sangle ou branche unique de bracelet facilite sa mise en œuvre. Le cas échéant, les contacts électriques peuvent être également répartis sur deux branches d'un bracelet. The switching contacts 21B, 22B are reliable. The location of the switches on a strap or single branch of bracelet facilitates its implementation. If necessary, the electrical contacts can be equally distributed on two branches of a bracelet.
L' invention aussi l'avantage d'utiliser et /ou de légèrement adapter un roduit très courant réduisant ainsi l'impact de coût . The invention also has the advantage of using and / or slightly adapting a very common product, thus reducing the cost impact.
