  • Publication number: 20240102307
    Abstract: A method for loading a four-wheeled vehicle using a transporter comprising wedging arms that are arranged so as to be positioned on either side of the tread of a wheel of the vehicle to be loaded, and wheel clamping detection means, the method comprising the following steps: —a step of moving the transporter until a wedging arm comes into contact with the tread of a tire, —a step of moving the transporter along the longitudinal axis of the transporter for a predetermined distance or until a predetermined force is detected, —a step of stopping the transporter from moving and generating a signal representative of the mobility state of the vehicle: moving or stationary.

  • Patent number: 8333342
    Abstract: The invention relates to a flapping-wing flying vehicle, the vehicle including a frame having two pivots mounted thereon to pivot about two parallel hinge axes (X), each pivot carrying a respective wing, the vehicle including a first oscillation generator for causing the pivots to oscillate in order to cause the wings to flap, said first oscillation generator comprising: two arms (6), each secured to a respective pivot (2); two cranks (9), each hinged to the end of a respective one of the arms about respective axes (X1) parallel to the hinge axes (X) of the pivots; a connecting rod (10) hinged to the ends of the two cranks about axes (X2) parallel to the hinge axes (X) of the pivots; synchronization means (4) for synchronizing the rotation of the two pivots such that the rotations of the pivots are equal and opposite; two electric motors (7), each placed to cause one of the cranks to rotate relative to the associated arm; and control means (50) for controlling and synchronizing the speeds of rotation of the m
