Abstract

The sub-assembly has an antenna and position sensors disposed on the same insulated support, this sub-assembly configured such that mutual interference from the combination of antennae and position sensors, are avoided. The sub-assembly comprises antennae (4) and actuators (6.1 to 6.12) mounted on the same insulation support (30). The antennae (4) is linked via connection (42) to the micro transmitter/receiver (5 in fig 3). The actuators are linked via connections (62) to the control unit (7 in fig 3) to permit predetermined information selection. The support (30) is manufactured from dielectric substrate with flexibility to fit the circumference of a wrist watch. The antennae (4) extends over most (but not all) of the support allowing High Frequency (radio) and Low Frequency (actuator) signals to be routed from opposite sides of the watch, thereby reducing interference between the two blocs whilst maintaining thin overall structure.

Description

La présente invention est relative à un sous-ensemble comprenant une antenne apte à capter et/ou émettre un champ électromagnétique porteur de messages radiodiffusés et des capteurs de position disposés sur un même support, ce sous-ensemble étant destiné à être monté dans un dispositif portatif tel qu'une pièce d'horlogerie. La présente invention concerne ainsi en outre une pièce d'horlogerie comprenant un tel sous-ensemble et permettant notamment, à un utilisateur de composer, d'effectuer et de recevoir des appels téléphoniques.The present invention relates to a subset comprising an antenna capable of receiving and / or transmitting a electromagnetic field carrying radio messages and position sensors placed on the same support, this sub-assembly being intended to be mounted in a portable device such as a timepiece. The the present invention thus also relates to a part timepiece comprising such a sub-assembly and allowing in particular, a user to compose, perform and receive phone calls.

On connaít de la demande de brevet EP 0 766 152, au nom de la Demanderesse, une pièce d'horlogerie comportant une antenne apte à capter et/ou émettre un champ électromagnétique porteur de messages radiodiffusés. Cette antenne est formée sur un substrat diélectrique disposé dans une rainure de montage définie par l'espacement existant entre un premier et un deuxième boítier. Cette antenne peut être réalisée indépendamment des autres éléments de la pièce d'horlogerie et peut en outre être facilement montée dans la pièce d'horlogerie lors de l'assemblage de celle-ci.We know from patent application EP 0 766 152, at name of the Applicant, a timepiece including an antenna capable of picking up and / or emitting a field electromagnetic carrying radio messages. This antenna is formed on a dielectric substrate arranged in a mounting groove defined by the spacing existing between a first and a second housing. This antenna can be carried out independently of the others elements of the timepiece and can furthermore be easily mounted in the timepiece when assembling it.

On connaít de plus de la demande de brevet EP 0 715 233, également au nom de la Demanderesse, une pièce d'horlogerie comportant des moyens de sélection d'une information numérique prédéterminée. Ces moyens de sélection sont formés de capteurs de position ménagés dans des secteurs angulaires définis sur la périphérie de la pièce d'horlogerie, par exemple, an regard des indications d'un affichage classique des heures. Les capteurs de position sont typiquement formés d'éléments capacitifs que l'utilisateur peut actionner par le positionnement d'un doigt. De tels capteurs de position sont décrits, par exemple, dans le brevet CH 623 195.We also know from patent application EP 0 715 233, also in the name of the Claimant, a document timepieces comprising means for selecting a predetermined digital information. These means of selection are formed by position sensors arranged in angular sectors defined on the periphery of the timepiece, for example, looking at the indications a classic hour display. The sensors position are typically formed of capacitive elements that the user can operate by positioning a finger. Such position sensors are described, by example, in patent CH 623 195.

L'antenne et les capteurs de position forment respectivement des premier et deuxième blocs indépendants situés tous deux dans une région périphérique de la pièce d'horlogerie. La séparation de ces deux blocs augmente, d'une part, l'encombrement de la pièce d'horlogerie. D'autre part, le montage des capteurs de position dans la pièce constitue également une opération relativement délicate et complexe.The antenna and the position sensors form first and second independent blocks respectively both located in a peripheral region of the room of watchmaking. The separation of these two blocks increases, on the one hand, the size of the timepiece. On the other hand, the mounting of the position sensors in the piece also constitutes a relatively operation delicate and complex.

La présente invention a ainsi pour but de fournir un sous-ensemble combinant une antenne et des capteurs de position sur un même support de manière à an simplifier la construction ainsi que le montage, notamment dans une pièce d'horlogerie. Par ailleurs, la présente invention a an outre pour but de réduire l'encombrement du dispositif portatif, par exemple une pièce d'horlogerie, dans lequel ce sous-ensemble est susceptible d'être monté.The present invention thus aims to provide a sub-assembly combining an antenna and sensors position on the same support so as to simplify the construction as well as assembly, especially in a timepiece. Furthermore, the present invention has an addition to reduce the size of the device portable, for example a timepiece, in which this sub-assembly is capable of being mounted.

Il est à noter toutefois que la combinaison des blocs périphériques formés respectivement par l'antenne et par les capteurs de position engendre des perturbations du fonctionnement du sous-ensemble. En effet, du point de vue électrique, l'antenne et les capteurs de position constituent respectivement un bloc haute-fréquence et un bloc basse-fréquence pouvant mutuellement interférer. La présence des capteurs de position à proximité de l'antenne affecte an effet le fonctionnement de celle-ci. Réciproquement, un rayonnement émanant de l'antenne affecte le fonctionnement des capteurs et de leur électronique de contrôle par couplage.It should be noted, however, that the combination of peripheral blocks formed respectively by the antenna and by the position sensors generates disturbances of the operation of the sub-assembly. Indeed, from the point of view electric, antenna and position sensors constitute respectively a high-frequency block and a low-frequency block that can mutually interfere. The presence of position sensors near the antenna affects the functioning of the latter. Conversely, radiation emanating from the antenna affects the operation of the sensors and their electronic control by coupling.

La combinaison des deux blocs périphériques constitue de ce fait une opération a priori peu souhaitable pour l'homme du métier. La présente invention a ainsi également pour but de fournir un sous-ensemble combinant de manière optimale une antenne et des capteurs de position sur un même support de telle sorte que le fonctionnement respectif de ceux-ci ne soit pas perturbé. The combination of the two peripheral blocks constitutes therefore an operation a priori undesirable for the skilled person. The present invention thus also has aim to provide a subset combining so optimal antenna and position sensors on a same support so that the operation respective of these is not disturbed.

A cet effet, la présente invention a pour objet un sous-ensemble destiné à être monté dans un dispositif portatif permettant la réception et/ou la transmission de messages radiodiffusés ainsi que la sélection d'une information prédéterminée, ce sous-ensemble étant caractérisé en ce qu'il comporte, disposés sur un même support isolant, une antenne comprenant un élément rayonnant apte à capter et/ou émettre un champ électromagnétique porteur desdits messages radiodiffusés, et des capteurs de position agencés pour permettre ladite sélection d'informations numériques prédéterminées.To this end, the present invention relates to a sub-assembly intended to be mounted in a device portable allowing the reception and / or the transmission of broadcast messages as well as the selection of a predetermined information, this subset being characterized in that it comprises, arranged on the same insulating support, an antenna comprising an element radiant capable of picking up and / or emitting a field electromagnetic carrying said broadcast messages, and position sensors arranged to allow said selection of predetermined digital information.

La présente invention a en outre pour objet une pièce d'horlogerie comprenant un sous-ensemble tel que défini ci-dessus.The present invention further relates to a part timepieces including a subset as defined above.

Un avantage de la présente invention réside ainsi dans le fait que le sous-ensemble antenne-capteurs est indépendant des autres composants du dispositif portatif dans lequel celui-ci est susceptible d'être monté. En conséquence, la présente invention permet une simplification de la construction et, par là même, une plus grande flexibilité lors de la fabrication. Par ailleurs, cet avantage se répercute également sur le montage et l'assemblage du dispositif portatif dans sa totalité.An advantage of the present invention thus lies in that the antenna-sensor sub-assembly is independent of other components of the portable device in which it is capable of being mounted. In Consequently, the present invention allows a simplification of construction and, thereby, a greater flexibility during manufacturing. Through elsewhere, this advantage also affects the mounting and assembling the portable device in its whole.

Un autre avantage de la présente invention réside dans le fait que la combinaison des deux blocs périphériques permet de réduire l'encombrement du dispositif portatif dans lequel ce sous-ensemble est susceptible d'être monté.Another advantage of the present invention lies in the fact that the combination of the two blocks devices reduces the size of the portable device in which this subset is likely to be fitted.

Encore un autre avantage de la présente invention réside dans le fait que l'agencement de l'antenne et des capteurs de position selon la présente invention permet de remédier aux perturbations mutuelles engendrées par la combinaison des deux blocs périphériques, et de rendre ainsi optimal le fonctionnement du sous-ensemble.Yet another advantage of the present invention is that the arrangement of the antenna and position sensors according to the present invention allows remedy the mutual disturbances caused by the combination of the two peripheral blocks, and make thus optimal operation of the sub-assembly.

D'autres caractéristiques et avantages de la présente invention apparaítront à la lecture de la description détaillée qui suit, faite en référence aux dessins annexés donnés uniquement à titre d'exemple et dans lesquels :

  • la figure 1 représente une vue en plan d'une pièce d'horlogerie selon la présente invention;
  • la figure 2 présente un mode de réalisation d'un sous-ensemble combinant, sur une face d'un support, une antenne, et sur l'autre face du même support, des capteurs de position selon la présente invention;
  • la figure 3 est une vue en plan simplifiée de la pièce d'horlogerie selon la présente invention, illustrant l'ensemble portant l'antenne et les capteurs de position de la figure 2 dans sa position de montage; et,
  • la figure 4 est une vue en coupe de la pièce d'horlogerie de la figure 1.
Other characteristics and advantages of the present invention will appear on reading the detailed description which follows, given with reference to the appended drawings given solely by way of example and in which:
  • FIG. 1 represents a plan view of a timepiece according to the present invention;
  • FIG. 2 shows an embodiment of a subassembly combining, on one face of a support, an antenna, and on the other face of the same support, position sensors according to the present invention;
  • Figure 3 is a simplified plan view of the timepiece according to the present invention, illustrating the assembly carrying the antenna and the position sensors of Figure 2 in its mounting position; and,
  • FIG. 4 is a sectional view of the timepiece of FIG. 1.

On a représenté à la figure 1, une vue en plan d'une pièce d'horlogerie selon la présente invention. Cette pièce d'horlogerie, ici sous la forme d'une montre bracelet 1, comporte un boítier 2 et un bracelet 3. Le boítier 2 comprend en outre une source d'alimentation en énergie 11 et des organes d'affichages de l'heure comprenant notamment un mouvement d'horlogerie 8, un cadran 9, et des aiguilles 10.There is shown in Figure 1, a plan view of a timepiece according to the present invention. This timepiece, here in the form of a watch bracelet 1, includes a case 2 and a bracelet 3. The housing 2 further comprises a power source 11 energy and time display organs comprising in particular a clockwork movement 8, a dial 9, and hands 10.

Afin de capter un champ électromagnétique porteur de messages radiodiffusés, la pièce d'horlogerie 1 comprend une antenne 4 enroulée dans une région périphérique du boítier 2. Un micro émetteur-récepteur 5 est relié à l'antenne 4 de manière qu'il reçoive ou émette des messages à l'aide de cette dernière et transforme ensuite ces messages en données perceptibles par le porteur de la pièce d'horlogerie 1, par exemple, en émettant des signaux sonores.In order to capture an electromagnetic field carrying radio messages, timepiece 1 includes an antenna 4 wound in a peripheral region of the case 2. A micro transceiver 5 is connected to antenna 4 so that it receives or transmits messages using the latter and then transforms these messages in data perceivable by the bearer of the timepiece 1, for example, by emitting signals sound.

La pièce d'horlogerie 1 comprend en outre des moyens permettant de sélectionner et d'entrer une information prédéterminée, par exemple une information numérique, notamment pour permettre la composition de numéros de téléphone. A cet effet, la pièce d'horlogerie 1 comporte des capteurs de position 6.1 à 6.12 ménagés dans des secteurs angulaires sur la pièce d'horlogerie 1, et des moyens électroniques de contrôle 7 des capteurs de positions 6.1 à 6.12 disposés à l'intérieur du boítier 2.The timepiece 1 further comprises means for selecting and entering information predetermined, for example digital information, in particular to allow the composition of numbers of phone. For this purpose, the timepiece 1 comprises position sensors 6.1 to 6.12 formed in angular sectors on timepiece 1, and electronic control means 7 of the sensors positions 6.1 to 6.12 arranged inside the housing 2.

Dans l'exemple illustré à la figure 1, les capteurs de position 6.1 à 6.12 sont avantageusement placés sur une lunette 20 de la pièce d'horlogerie 1. On notera, en outre, que les capteurs de position 6.1 à 6.12 sont placés, de manière non limitative, en regard des indications horaires d'un affichage classique de l'heure. Il est à noter qu'une autre variante envisageable peut consister à placer les capteurs de position 6.1 à 6.12 non pas sur la lunette mais sous une glace de la pièce d'horlogerie.In the example illustrated in Figure 1, the sensors of position 6.1 to 6.12 are advantageously placed on a bezel 20 of the timepiece 1. It will be noted, in furthermore, that the position sensors 6.1 to 6.12 are placed, without limitation, opposite the time indications of a classic time display. It should be noted that another possible variant may consist in positioning the position sensors 6.1 to 6.12 no not on the telescope but under a piece of glass of watchmaking.

Dans la figure 1, les capteurs de position 6.1 à 6.12 sont respectivement placés en regard des indications horaires 1h à 12h. Il est à noter également que cette disposition particulière n'est en rien limitative. Toutefois, la disposition de ces capteurs de position par rapport à l'antenne 4 doit être réalisée, comme on le verra ci-après, de sorte à ne pas perturber le fonctionnement de cette dernière.In Figure 1, the position sensors 6.1 to 6.12 are respectively placed next to the indications hours 1h to 12h. It should also be noted that this particular provision is in no way limiting. However, the arrangement of these position sensors by compared to antenna 4 must be carried out, as will see below, so as not to disturb the operation of the latter.

Le positionnement d'un doigt d'un utilisateur de la pièce d'horlogerie 1 sur un des capteurs de position 6.1 à 6.12 provoque la sélection de l'information numérique correspondante. En l'occurrence, le cadran 9 comporte, par exemple, des indications "1" à "9" et "0" respectivement confondues avec les indications 1h à 9h et 10h de l'affichage classique de l'heure, de manière à ce que l'utilisateur puisse composer un appel en activant successivement les capteurs de position correspondants 6.10 et 6.1 à 6.9. Le fonctionnement des moyens de sélection et d'entrée des informations numériques ne sera pas décrit plus en détail ici. Une explication détaillée du fonctionnement d'un tel dispositif peut en effet être trouvée dans la demande de brevet EP 0 715 233, au nom de la Demanderesse, déjà citée en préambule.The positioning of a finger of a user of the timepiece 1 on one of the position sensors 6.1 to 6.12 causes the selection of digital information corresponding. In this case, the dial 9 comprises, by example, indications "1" to "9" and "0" respectively combined with the indications 1h to 9h and 10h from the classic time display, so that the user can dial a call by activating successively the corresponding position sensors 6.10 and 6.1 to 6.9. The functioning of the means of selection and input of digital information will only not described in more detail here. A detailed explanation of the operation of such a device can indeed be found in patent application EP 0 715 233, in the name of the Applicant, already cited in the preamble.

La figure 2 présente un mode de réalisation d'un sous-ensemble combinant l'antenne 4 et des capteurs de position 6.1 à 6.12 selon la présente invention. L'antenne 4 et les capteurs de positions 6.1 à 6.12 sont disposés sur un même support isolant 30. Ce support isolant 30 est de préférence flexible afin de faciliter l'assemblage de l'antenne 4 et des capteurs de position 6.1 à 6.12 dans la pièce d'horlogerie. A cet égard, il est convenable d'utiliser comme support isolant, un substrat diélectrique polyimide d'environ 100 µm d'épaisseur.Figure 2 shows an embodiment of a sub-assembly combining the antenna 4 and sensors position 6.1 to 6.12 according to the present invention. The antenna 4 and the position sensors 6.1 to 6.12 are arranged on the same insulating support 30. This insulating support 30 is preferably flexible in order to facilitate the assembly of antenna 4 and position sensors 6.1 to 6.12 in the timepiece. In this regard, it is suitable to use as an insulating support, a dielectric substrate polyimide about 100 µm thick.

L'antenne 4 est formée de préférence sur une face (à l'arrière-plan dans la figure 2) du support isolant 30. Elle comprend un élément conducteur en circuit imprimé définissant un élément rayonnant 40 de l'antenne 4. Cet élément est constitué de préférence par un dépôt métallique sur le support isolant 30.The antenna 4 is preferably formed on one face (at the background in FIG. 2) of the insulating support 30. It includes a conductive element in printed circuit defining a radiating element 40 of the antenna 4. This element preferably consists of a deposit metal on the insulating support 30.

L'élément conducteur 40 définit un dipôle dont la longueur est, de préférence, environ égale à λ/2, où λ est la longueur d'onde de travail de l'antenne, c'est-à-dire la longueur d'onde du signal électromagnétique utilisé pour émettre et/ou recevoir les messages radiodiffusés.The conductive element 40 defines a dipole whose length is preferably about λ / 2, where λ is the working wavelength of the antenna, i.e. the wavelength of the electromagnetic signal used to send and / or receive broadcast messages.

L'antenne 4 comporte, en outre, à mi-longueur de l'élément rayonnant 40, un point de contact 42 permettant de relier celle-ci au micro émetteur-récepteur 5. Lors du montage l'antenne est dirigée vers l'extérieur pour une efficacité optimale.The antenna 4 also comprises, at mid-length of the radiating element 40, a contact point 42 allowing to connect it to the micro transceiver 5. When mounting the antenna is directed outwards for a optimal efficiency.

Les capteurs de position 6.1 à 6.12 sont disposés sur la face opposée (au premier plan dans la figure 2) du support isolant 30. Lors du montage, ces capteurs sont ainsi dirigés vers l'intérieur de la pièce d'horlogerie. Des lignes de connexion 60.1 à 60.12 permettant de connecter les capteurs de position 6.1 à 6.12 sont en outre disposées sur le support isolant 30 de manière à relier ceux-ci aux moyens électroniques de contrôle 7. A cet effet, une plage de contact 62 est disposée à une extrémité du support isolant 30.The position sensors 6.1 to 6.12 are arranged on the opposite side (in the foreground in Figure 2) of the insulating support 30. During assembly, these sensors are thus directed towards the interior of the timepiece. Connection lines 60.1 to 60.12 allowing connect the position sensors 6.1 to 6.12 are in additionally arranged on the insulating support 30 so as to link these to electronic control means 7. A For this purpose, a contact pad 62 is arranged at a end of the insulating support 30.

Afin de remédier aux perturbations du fonctionnement de l'antenne 4 engendrées par la présence des capteurs de positions 6.1 à 6.12 et des lignes de connexion 60.1 à 60.12, ces derniers sont disposés de façon qu'ils forment, lorsque le sous-ensemble antenne-capteurs est monté dans la pièce d'horlogerie 1, un agencement symétrique par rapport à l'antenne 4. Les lignes de connexion 60.1 et 60.12 en outre sont disposées de façon à perturber le moins possible l'antenne située sur l'autre face.In order to remedy operating disturbances the antenna 4 generated by the presence of the positions 6.1 to 6.12 and connecting lines 60.1 to 60.12, the latter are arranged so that they form, when the antenna-sensor sub-assembly is mounted in timepiece 1, a symmetrical arrangement by relative to the antenna 4. Connection lines 60.1 and 60.12 are furthermore arranged to disturb the less possible the antenna located on the other side.

A titre explicatif, on a ainsi illustré à la figure 3, sous la forme d'une vue plan simplifiée de la pièce d'horlogerie 1, le sous-ensemble antenne-capteurs de la figure 2 dans sa position de montage. A l'état monté, les capteurs de position 6.1 à 6.12 sont ainsi disposés de sorte à former un agencement symétrique autour de l'élément rayonnant 40, soit de part et d'autre du point de contact 42 de l'antenne 4. On constate ainsi sur les figures 2 et 3, qu'un axe de symétrie de l'antenne 4 passe par le capteur de position référencé 6.9.By way of explanation, we have thus illustrated in FIG. 3, in the form of a simplified plan view of the part 1, the antenna-sensor sub-assembly of the Figure 2 in its mounting position. In the assembled state, the position sensors 6.1 to 6.12 are thus arranged so as to form a symmetrical arrangement around the radiating element 40, either on either side of the point contact 42 of the antenna 4. It can thus be seen on the Figures 2 and 3, that an axis of symmetry of the antenna 4 passes by the position sensor referenced 6.9.

Il est à noter que la disposition particulière des capteurs de positions 6.1 à 6.12 telle que présentée dans le mode de réalisation illustré aux figures 2 et 3 n'est nullement limitative. Il est en effet possible de prévoir d'autres dispositions de l'antenne 4 et/ou des capteurs de position 6.1 à 6.12 pour lesquelles une symétrie de l'ensemble est également obtenue. En particulier, les capteurs de position 6.1 à 6.12 représentés aux figures 2 et 3 pourraient être disposés de sorte à ce que l'axe de symétrie de l'antenne 4 passe entre deux capteurs de position adjacents.It should be noted that the special arrangement of position sensors 6.1 to 6.12 as presented in the embodiment illustrated in FIGS. 2 and 3 is not in no way limitative. It is indeed possible to predict other arrangements of the antenna 4 and / or of the positions 6.1 to 6.12 for which a symmetry of the whole is also obtained. In particular, position sensors 6.1 to 6.12 shown in Figures 2 and 3 could be arranged so that the axis of symmetry of the antenna 4 passes between two sensors adjacent position.

De manière à éviter qu'un rayonnement émanant de l'antenne 4 ne vienne perturber par couplage l'électronique de contrôle 7 des capteurs de position 6.1 à 6.12, des composants additionnels de filtrage (non représentés) sont en outre prévus sur les lignes de connexion 60.1 à 60.12.In order to prevent radiation from antenna 4 does not interfere with coupling the control electronics 7 of the position sensors 6.1 in 6.12, additional filtering components (not shown) are also provided on the lines of connection 60.1 to 60.12.

La figure 4 est une vue en coupe simplifiée selon un axe 9h-3h de la pièce d'horlogerie de la figure 1. Celle-ci comprend le boítier 2, le micro émetteur-récepteur 5 associé à l'antenne 4, l'électronique de contrôle 7 des capteurs de position 6.1 à 6.12, le mouvement d'horlogerie 8 et la source d'alimentation en énergie 11. Figure 4 is a simplified sectional view along a 9h-3h axis of the timepiece of Figure 1. This includes the housing 2, the micro transceiver 5 associated with the antenna 4, the control electronics 7 position sensors 6.1 to 6.12, the clockwork movement 8 and the power supply source 11.

Le support isolant 30 de la figure 2 portant l'antenne 4 et les capteurs de position 6.1 à 6.12 est enroulé dans une région périphérique du boítier 2.The insulating support 30 of FIG. 2 carrying the antenna 4 and the position sensors 6.1 to 6.12 is wound in a peripheral region of the housing 2.

De préférence, les capteurs de position 6.1 à 6.12 sont en outre recourbés radialement vers l'intérieur de la pièce d'horlogerie 1, comme cela est représenté dans la figure 4, de telle sorte qu'ils viennent appuyer sur une surface intérieure 22 de la lunette 20 de façon à optimiser la sensibilité de ces capteurs.Preferably, the position sensors 6.1 to 6.12 are also bent radially inward of the timepiece 1, as shown in the figure 4, so that they come to press on a inner surface 22 of the bezel 20 so as to optimize the sensitivity of these sensors.

En outre, une bague interne 40 est de préférence disposée dans le boítier 2 de la pièce d'horlogerie de sorte à ce que le support isolant 30 soit pris en sandwich entre le boítier 2 et la bague interne 40. Cette bague interne 40 permet en outre d'assurer que les capteurs de positions 6.1 à 6.12 appuient correctement sur la surface intérieure 22 de la lunette 20 de sorte que le fonctionnement des capteurs est optimisé.In addition, an internal ring 40 is preferably arranged in the housing 2 of the timepiece of so that the insulating support 30 is sandwiched between the housing 2 and the inner ring 40. This ring internal 40 further ensures that the positions 6.1 to 6.12 press correctly on the surface inner 22 of the bezel 20 so that the sensor operation is optimized.

On peut constater que l'agencement formé par la combinaison de l'antenne 4 et des capteurs de position 6.1 à 6.12 sur le même support, selon la présente invention, permet de simplifier dans une large mesure la fabrication ainsi que le montage de l'antenne et des capteurs.We can see that the arrangement formed by the combination of antenna 4 and position sensors 6.1 to 6.12 on the same support, according to the present invention, greatly simplifies manufacturing as well as the mounting of the antenna and the sensors.

Enfin, il est à noter que plusieurs modifications et/ou améliorations peuvent être apportées à la pièce d'horlogerie selon la présente invention sans sortir du cadre de celle-ci. En particulier, l'agencement des capteurs de position sur le support isolant présenté dans le mode de réalisation de la figure 2 n'est pas limitatif.Finally, it should be noted that several modifications and / or improvements can be made to the room of watchmaking according to the present invention without departing from the part of it. In particular, the arrangement of position sensors on the insulating support presented in the embodiment of Figure 2 is not limiting.
