Abstract

La présente invention concerne un système comprenant un appareil portatif et un appareil fixe. L'appareil portatif et l'appareil fixe comprennent, respectivement, une unité de commande et une unité de communication. Une unité de détection de proximité, qui détecte que l'appareil portatif se trouve dans un état de proximité lui permettant d'être localisé à proximité de l'appareil fixe, est disposée sur l'appareil portatif et/ou sur l'appareil fixe. Lorsque l'état de proximité est détecté, l'unité de commande de l'appareil portatif transmet au dispositif fixe des informations de fonctionnement qui représentent un état de fonctionnement à cet instant et/ou des informations de configuration qui représentent un état de configuration de fonction à cet instant. Lorsque les informations de fonctionnement et/ou les informations de configuration sont reçues, l'unité de commande de l'appareil fixe lance une fonction sur la base des informations reçues. L'unité de commande de l'appareil portatif interrompt une fonction sur la base des informations transmises au dispositif fixe.
