A method and device for triggering, via an RFID reader () endowed with a transmitting antenna (), a procedure for actuating an element for locking/unlocking the access doors () of a motor vehicle (). A coil () is arranged in the vicinity and in the field of action of the transmitting antenna (), and:

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. The electromagnetic signals incorporate a final portion consisting of a pure wave, and the activation of the radio-tags is done so as to insert the location codes into the electromagnetic signals by modulating the absorption/reflection of the pure waves.

This sensitive surface comprises two films () facing each other and means for keeping these two films a certain distance apart when no pressure is exerted on the surface. Each film () has, on its face turned toward the other film: 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.

Touch-sensitive surface which is also sensitive to pressure levels

This system includes a control part ( ) 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.
