Abstract: A light unmanned vertical take-off aircraft includes at least two fixed coplanar propulsion devices and at least one wing providing the lift for the drone. The coplanar propulsion devices and the wing are each laid out on the frame of the drone so that the plane of the profile chord line of the wing is substantially parallel to the plane defined by the two coplanar propulsion devices. The wing is pivotingly mobile relative to the frame along an axis parallel to the pitch axis of the drone. Also a method is provided for controlling orientation of a wing of a light unmanned vertical take-off aircraft as described here above. The method includes controlling an orientation of a wing as a function of at least one flight parameter of the aircraft.

Abstract: The present invention relates to a roaming electronic transaction terminal. It also relates to a secure system for electronic transactions comprising one or more roaming terminals. The terminal (1) has an application package support (2) and a coupler (3) for carrying out the read and write operations on a medium that are required for the electronic transactions in conjunction with the application package. The coupler (3) comprises means for creating a write time window and a read time window on the basis of a secure input signal, all writing and all reading being disabled outside of the corresponding windows. The invention applies notably for the securing of terminals carrying out checks and contractual transactions on supports equipped with processors and memories, it being possible for these supports to be through contactless read and write cards comprising for example transport entitlements, payment means or any other entitlements to be turned to account.

Abstract: The invention relates to a damping device, in particular for mounting a support plate (10) comprising a cylindrical damper unit (12) with a main axis (A) that comprises a top radial flange (20s) and a bottom radial flange (20i) which are cylindrical and each of which is accommodated by one side in a horizontal plate (18) of the plate (10), wherein the plate (10) comprises at least one cylindrical flange (26s, 26i) supported by the horizontal plate (18) which extends opposite the outer cylindrical surface (20e) of an associated flange (20s, 20i). characterized in that the flange ring (26s, 26i) comprises a concave inner cylindrical surface (26a) which is capable of resting radially against a convex outer cylindrical surface (20e) of the flange (20s, 20i), in at least one overall horizontal direction.

Abstract: The invention provides an arrangement of the type that comprises a spacer which is attached to the body structure element, and an attachment tab (12) in which the front longitudinal end (12a) is attached to the spacer by means of a shock absorber element (16) with a tubular shape that is coaxial in relation to the spacer and in which the outer cylindrical wall comprises a peripheral groove with the attachment tab (12) resting against the bottom (22) of said groove, and of the type in which the front end of the attachment tab (12) comprises a C-shaped housing (20) in which the shock absorber element (16) is accommodated, characterised in that longitudinal free play exists between the rear section (28) and the bottom (22) of the peripheral groove (18) opposite it.

Abstract: An arrangement for fixing a wiper device for a motor vehicle includes at least one stand for guiding and fixing a drive shaft that extends axially in a substantially vertical direction. The stand includes a barrel in which the shaft is guided in rotation, and a horizontal base plate for fixing the stand to a structural element of the vehicle, by a damper block made of an elastically deformable material. The damper block is fixed to the structural element by a fixing element, which includes a vertical rod that passes through the damper block and is connected to the structural element, and an element for locking the damper block on the structural element. The rod and locking element are connected by connection means for enabling the rod and locking element to disconnect, through downward sliding of the locking element with respect to the rod, when subjected to a violent impact.

Abstract: A method is disclosed for assembling a windscreen-wiper mechanism having a support plate on an internal face of a body structure element that extends globally vertically at a rear of a motor vehicle. The method includes the steps of positioning the support plate relative to the internal face of the body structure element and joining the plate to the internal face of the body structure element. The positioning step includes moving the plate relative to the body structure element along a first direction, and the joining step includes rotating the plate about the first direction.

Abstract: A screen wiper for a motor vehicle comprises a wiper arm carrying a wiper blade and applying a wiping pressure, so as to urge the latter against the windshield of the vehicle as the arm is oscillated in the usual way across the windshield by a drive spindle, which carries a drive head on which the wiper arm is fitted. The wiper arm carries a guide bracket which, in the parked position of the wiper, cooperates with an engagement surface of a ramp fixed to the vehicle body, so as to lift the wiper arm and so relieve the wiping pressure. The guide bracket has an indexing claw which cooperates with a claw formed on the ramp to define a precise angular orientation of the wiper for fitting of the latter on to the drive head.

Abstract: A device for fastening to the body of a motor vehicle an assembly comprising a support plate, is of the type comprising a bolt-and-nut assembly. The threaded shank of the bolt passes through a hole in the support plate, a hole formed in a damping ring which is interposed between the support plate and a first face of a bodywork element of the vehicle, and a hole in the bodywork element itself. The bolt is screwed into a nut which is located beyond the opposite face of the bodywork element, and which is received in a nut retaining cage. The damping ring and the cage are made integrally with each other as a single assembly member of elastomeric material or rubber; the portion of this assembly member that defines the cage deforms in expansion while the nut is being tightened on to the bolt.
