Abstract: A method and device for triggering, via an RFID reader (5) endowed with a transmitting antenna (6), a procedure for actuating an element for locking/unlocking the access doors (2) of a motor vehicle (1). A coil (7) is arranged in the vicinity and in the field of action of the transmitting antenna (6), and: the RFID reader (5) is commanded so as to control the successive transmission of electromagnetic pulses of the same power, upon each pulse, a value representative of the electrical voltage at the terminals of the coil (7) is measured, and the procedure for actuating the locking/unlocking element is triggered in the event of a variation in the measured values greater than a determined value.

Abstract: A method and device for locating n wheels of a vehicle each equipped with an electronic module designed to emit, to a central unit, electromagnetic signals representative of operating parameters of each wheel and an identification code of the latter. There is, in a fixed position on the vehicle, in the vicinity of at least (n-1) wheels, a radio-tag in which is stored a location code, able to be identified by the central unit and enable the latter to locate the position of the radio-tag on the vehicle. In order to locate the wheels, an activation of each radio-tag is controlled so as to deliver to the central unit a signal incorporating the location code of this radio-tag associated with the identification code of the wheel located in the vicinity of the latter.

Abstract: This sensitive surface comprises two films (2, 4) facing each other and means for keeping these two films a certain distance apart when no pressure is exerted on the surface. Each film (2, 4) has, on its face turned toward the other film: an array of conducting tracks (6, 8) that do not touch one another, each having a low resistance; a resistive band (12, 16); and resistive elements (10, 14), each resistive element connecting a conducting track to the resistive band. To measure the pressure level exerted on this sensitive surface, the resistance equivalent to the resistance of the resistive elements lying in series and in parallel, after at least two conducting tracks have been brought into contact with each other, is measured.

Abstract: This system includes a control part (6) permitting controlling the opening and closing of an associated window, having three separate control zones (F, M, O). In the automatic mode, when the corresponding window has been entirely opened or closed, a push on a predetermined control zone advantageously controls the movement of the window into the position in which it was before its complete opening or closing.
