Abstract: A roof-cleaning device for moving side windows of a convertible vehicle an appropriate distance clear of a roof hinged to the vehicle body, and capable of detecting an event in or in the surroundings of the vehicle, includes: a first motion detector designed to occupy a first operational state and a second standby state, and a second detector coupled to the first detector and of lower power consumption, wherein I. with the first detector in the standby state, if the second detector detects an event to which it is sensitive, then the first detector switches into the operational state so that it can play a part in moving the window clear of the roof, II. and if, while in this operational state, the first detector detects the presence, intervention or action of the individual, then the windows are rolled down before the door is, or can be, opened.

Abstract: A method and device for filtering electromagnetic interference generated by the antenna of a transmitter on a sensor sensitive to electromagnetic waves, characterized in that it includes: vi. elements suitable for sampling the signal received by the sensor, vii. elements for count down the elapsed time, called the detection time, after the sampled signal has exceeded a threshold value, the signal, before exceeding the threshold value, being in a range of standard values, viii. elements for comparing in real time the detection time with a threshold time value, ix. elements suitable for providing a diagnosis of electromagnetic interference to be filtered if the sampled signal reverts to a standard value after a detection time of less than the threshold time value, and a diagnosis of an uninterfered sampled signal if this is not the case, x. elements for generating an output signal from the sensor eliminating the diagnosed electromagnetic interference.
