METHOD OF ACCESS BY A MASTER DEVICE TO A VALUE TAKEN BY A CHARACTERISTIC MANAGED BY A PERIPHERAL DEVICE

L'invention concerne une technique d'accès par un dispositif maître (22) à une valeur prise par une caractéristique gérée par un dispositif périphérique (23). Un premier dispositif relais (21) se trouvant dans une zone de couverture radio du dispositif maître reçoit une commande de simulation du dispositif périphérique, ce dispositif périphérique se trouvant dans une zone de couverture radio d'un deuxième dispositif relais (24). Le premier dispositif relais établit alors une connexion radio avec le dispositif maître, en simulant la présence du dispositif périphérique dans la zone de couverture radio du dispositif maître. Le premier dispositif relais reçoit en provenance du dispositif maître une demande de lecture d'une valeur prise par une caractéristique gérée par le dispositif périphérique, transmet la demande et reçoit en retour la valeur en provenance du deuxième dispositif relais, ledit deuxième dispositif relais l'ayant obtenue par interrogation du dispositif périphérique. Il peut alors l'envoyer au dispositif maître.. The invention relates to a technique of access by a master device (22) to a value taken by a characteristic managed by a peripheral device (23). A first relay device (21) in a radio coverage area of the master device receives a simulation command from the peripheral device, which peripheral device is in a radio coverage area of a second relay device (24). The first relay device then establishes a radio connection with the master device, simulating the presence of the peripheral device in the radio coverage area of the master device. The first relay device receives from the master device a request to read a value taken by a characteristic managed by the peripheral device, transmits the request and receives back the value from the second relay device, said second relay device having obtained by interrogation of the peripheral device. He can then send it to the master device.

RIPING DEVICE FOR PRECISION ASSEMBLY

La présente invention concerne un dispositif (1) de rivetage pour assembler entre elles deux pièces (2) comportant chacune un alésage (7), remarquable en ce qu'il comporte un rivet externe (11) indéformable comprenant un corps tubulaire (12) apte à être inséré dans lesdits alésages (4) et muni à l'une de ses extrémités longitudinales d'une bride (13), et un rivet interne (14) comprenant un corps cylindrique (15) plein déformable et issu sensiblement perpendiculairement d'un flasque (16), ledit corps tubulaire (12) ayant un diamètre extérieur légèrement inférieur au diamètre desdits alésages (7) et une longueur D entre la face arrière (131) de sa bride (13) et son extrémité opposée au plus égale à la somme des épaisseurs des pièces (2), ledit corps cylindrique (15) ayant une section transversale extérieure homothétique légèrement inférieure à la section transversale intérieure du corps tubulaire (12), et une longueur légèrement supérieure à celle du corps tubulaire (12). The present invention relates to a riveting device (1) for assembling together two parts (2) each comprising a bore (7), remarkable in that it comprises an external rivet (11) which cannot be deformed comprising a tubular body (12) suitable for to be inserted into said bores (4) and provided at one of its longitudinal ends with a flange (13), and an internal rivet (14) comprising a solid cylindrical body (15) deformable and issuing substantially perpendicularly from a flange (16), said tubular body (12) having an outer diameter slightly less than the diameter of said bores (7) and a length D between the rear face (131) of its flange (13) and its opposite end at most equal to the sum of the thicknesses of the parts (2), said cylindrical body (15) having an exterior cross section which is homothetic slightly smaller than the interior cross section of the tubular body (12), and a length slightly greater than that of the tubular body (12).
