Patent

CA 2497140

The invention relates to watches, generally wristwatches, with cases comprising built-in electronic information-storage units. The aforementioned units consist of an integrated circuit chip which is connected to an antenna comprising a coil and can communicate by means of broadcast signals with a read and/or write device. The read and/or write device is used at least to read the information contained in a memory element of the integrated circuit chip and often to delete or modify at least one part of said information and to add other information. In order to eliminate the inconveniences associated with known watches of said type in which the information-storage units are located inside the case (more complicated production or novel design of case, increased case volume) or to diminish the significance of said inconveniences (attenuation and/or deformation of signals emitted or received by the coil), the electronic unit (14) of the inventive watch is housed for the most part at least in a cavity (13) which is open to the external environment and which is disposed in the base (3) of the case (1).

L'invention concerne les montres, généralement des montres-bracelets, dans les boîtes desquelles sont incorporés des modules électroniques pour la mémorisation d'informations qui comprennent une puce de circuit intégré reliée à une antenne constituée par une bobine et qui peuvent communiquer par des signaux radio-diffusés avec un appareil de lecture et/ou d'écriture prévu pour au moins lire les informations contenues dans une mémoire de la puce de circuit intégré et souvent pour pouvoir en plus supprimer ou modifier au moins une partie de ces informations et en ajouter d'autres. Pour éliminer les inconvénients de ces montres connues dans lesquelles les modules se trouvent à l'intérieur des boîtes (complication de la fabrication ou nouvelle conception de la boîte, augmentation du volume de celle-ci) ou diminuer l'importance de ces inconvénients (atténuation et/ou déformation des signaux émis et reçus par la bobine), dans la montre selon l'invention le module électronique (14) est logé au moins en majeure partie dans une cavité (13) ouverte vers l'extérieur que présente le fond (3) de la boîte (1).
