Abstract: The invention relates to a method of determining the characteristics of the voltage of an electrical installation which is powered by a generator. The inventive method comprises the following steps consisting in: generating at least one electrical disturbance between at least two points of an electric circuit, which are separated by a dielectric layer; observing a first electric current at the terminals of a first impedance; bringing an electrode into contact with a point of the electrical installation; observing a second electric current at the terminals of a second impedance; observing the change in the first electric current at the terminals of the first impedance; and determining the characteristics of the voltage of the installation from the change in the first electric current and the characteristics of the second electric current. The invention also relates to a device which is used to implement said method.

Abstract: This invention relates to a suspension for vehicles, wherein the wheels are associated with the bodywork by means of a flexible assembly essentially constituted by two longitudinal blades and by two transverse blades connected to the bodywork by means of elastically deformable connecting elements, wherein:--the ends of the longitudinal blades and transverse blades are located in two planes spaced apart from each other, these two planes being parallel or not;--at the front of the chassis, the ends of the longitudinal blades are mounted so as to allow a momentary longitudinal displacement under the effect of a shock and to avoid any transverse or angular displacement;--at the rear of the chassis, the ends of the longitudinal blades are blocked in torsion in the hub-holder elements.
