Abstract: An aircraft includes a central wing accommodating passengers and/or freight and two lateral wings that pivot on the central wing about respective axes of rotation. The various wings obey the following geometric characteristics: 0.3×Long<Larg<Long, 0.11×Long<Haut<0.25×Long, Env>1.4×Long, wherein Larg being the distance between the two axes, Long being the length of the central wing, Haut being the height of the central wing, Env being the wingspan of the aircraft. The axes of rotation are inclined by an angle relative to the vertical axis of the aircraft such that the lateral pivot from rear to front and vice versa so as to come closer to, or deploy on either side from, the fuselage.

Abstract: An aeroplane includes a fuselage having a pair of hydrofoils providing hydrodynamic lift and stabilization arranged in the form of an inverted V. The junction between each hydrofoil and fuselage is situated forward the center of gravity of the aeroplane. The distance separating the junction between each hydrofoil and the fuselage, with respect to the center of gravity of the aeroplane is comprised between 0 and 170% of the mean aerodynamic chord of the main wing of the aeroplane, preferably between 20% and 135%. Each hydrofoil is inclined downwards, from its leading edge in the direction of its trailing edge. The straight line connecting these two edges form, a nominal pitch angle comprised between 2 and 12°, preferably between 6 and 8°. A part of the hydrofoil is located beneath a horizontal tangential plane of the aeroplane; each hydrofoil has a flexible intermediate section allowing the hydrofoil to flex upwards.

Abstract: A motorized airplane includes a landing gear with at least two legs capable of retracting into the fuselage via hatches. A pair of hydrofoils is fitted to the base of the fuselage in conformance with the ailerons used for lift and hydrodynamic stability, directed towards the base like a reverse V shape. The legs of the landing gear are each articulated around the pivot axes, fitted onto the hydrofoils. The landing gear is dual-function, using wheels or skis suspended on legs. Applications: airplane for landing on water, ground and snow.

Abstract: A power supply system for an automobile vehicle headlight discharge lamp, the system including a DC/DC converter with a capacitor at its output, a DC/AC converter powered by the voltage across said capacitor, and a module for generating a high-voltage breakdown pulse designed to be connected in series with said discharge lamp to the output of the DC/AC converter, wherein it further includes a module for heating the electrodes of the discharge lamp design to be connected in series with the discharge lamp and the high-voltage pulse generator module and adapted to deliver, after the high-voltage breakdown pulse, a decreasing voltage which, at the terminals of said discharge lamp, is added to the voltage across the capacitor at the output of the DC/DC converter.

Abstract: An electronic assembly comprising a heat sink and a double-sided printed circuit card assembled to the heat sink by hot pressing. The card carries a plurality of surface-mounting components on its face remote from the heat sink. Further, the card carries at least one through component and the heat sink has a void over the zone of the printed circuit card which receives the through component. The ends of the pins of the component are bonded to the card inside the void.
