Abstract: The invention concerns a device comprising an electronic sensor (6) designed to deliver a compression signal and a shearing signal, and a comparator for comparing the shearing signal to a threshold value, so as to validate, or invalidate, the compression signal. The invention is useful for weighing aircraft.

Abstract: An actuator combining mechanical and hydraulic forces includes a cylindrical body and a piston that can slide relative to the cylindrical body. The piston and the cylindrical body are connected by a mechanical system for transmitting mechanical power that constitutes a device that permanently controls the position of the actuator, a permanent locking device, and a safety device. The device for transmitting hydraulic power constitutes a load compensator device. The two power transmitting devices operate in parallel. Position control using the drive system at reduced power can be synchronized in a simple way for a plurality of actuators.

Abstract: A device for actuating in rotation a mechanism and control stick incorporating the device, which includes, elastic means for applying to a control shaft (10) a reaction torque having a magnitude which is a function of the angle of rotation of the shaft comprise a cam follower structure (18, 24) which is slidably mounted on a reaction lever (22) having an axis Z--Z perpendicular to the control shaft (10) and which is elastically slidably biased so as to cooperate with a confronting cam profile (16) formed on a reaction member (42) relative to which the cam follower structure (24, 18) is moved when the control shaft (10) is rotated, the cam profile (16) extending in a plane perpendicular to the control shaft (10).
