The invention concerns a method and a system enabling users of an Internet type computer network provided with multimedia terminals comprising a microphone and connected to an Internet type computer network, remotely located from a service supplier, to accede rapidly and safely, to services offered by this service supplier. In a preferred embodiment, a characteristic force value for the system is frequently updated as a function of actual measured force requirements. The suspension within the substrate results in a compliant deflection orthogonal to the plane of the substrate. The systems, methods, and programs compare, for each of the plurality of links, the second degree of the traffic jam with the first degree of the traffic jam for each of the thresholds. The opening of the closure mechanisms are temporally controlled to occur slowly.
