Abstract:
A device for hierarchized access to a network for transmission of information by response in a communication frame, from stations connected to this network, including a counter (62) of bits transmitted on the network, connected to an input of a comparison block (63) for comparing the number of bits transmitted on the network with a characteristic value for the access ranking allocated to this station, the comparison block being connected to a transmission block (68) from the station in order to authorize the transmission of information on the network by this station when the number of bits transmitted on the network is at least equal to the characteristic value allocated to the station.

Abstract:
A transport trolley (CT) comprises: a pair of legs (J1) each having a lower end to which there is coupled a plate (PT1) on which at least one wheel (R1) is mounted so as to rotate in a transverse direction, first load supporting means (S1) coupled to the lower ends of the legs (J1), first coupling means (MC1) on which the lower ends of the legs (J1) are mounted so as to rotate in the transverse direction such that they can move from a folded-out position to a folded-away position, and on which the plates (PT1) are mounted so as to rotate such that wheels (R1) thereof can pivot and move from a folded-out position to a folded-away position approximately parallel to the folded-away legs (J1), and second coupling means (MC2) designed to force the legs (J1) and the wheels (R1) to be substantially simultaneously either in their folded-away position or in their folded-out position.
Abstract:
This device includes a signal processor (30,35,36,37,38,47,49) to generate sampling signals of information present on a network, and a selection circuit (43) for loading the signal processor with at least one synchronization value (44, 45) corresponding to at least one propagation time for information in the network to synchronize the station according to the transmission characteristics of the network.
Abstract:
A bearing structure includes a wheel assembly defining a first front wheel assembly and a second rear wheel assembly, the rear wheel assembly including at least two wheels spaced by a first width defining a first position; wheel supports connecting the axes of rotation of the wheels with the bearing structure; a first folding device enabling a first folding causing a reduction in spacing between the two rear wheels to a second width lower than the first width, defining a second position. A connection system, connecting the wheel supports of the first and second assemblies to the first folding device, enables a second folding of the wheels so as to allow a rotation substantially equal to 90° of the wheels in the horizontal plane when the wheels are in the second position.
