Abstract: A detector of stains on a transparent plate surface is arranged on an internal surface of the plate and includes an emitter for emitting a modulated light signal towards the inside of the plate and a receiver for receiving the signal after it has been reflected on an external surface of the plate. An optical unit made with a material having an index substantially higher than the plate, is arranged on the internal surface of the plate. The optical unit is made up of at least three faces returning the light signal and an interface with the internal surface of the plate through an optical coupler. A deflector deflects the signal from the emitter toward the plate and from the optical unit towards the receiver. At least two reflections on the external surface of the plate are produced through the optical coupler without reflection on the internal surface of the plate.

Abstract: The invention proposes a motor vehicle windscreen wiper of the type in which a cover, intended completely to cover over a drive head, includes two longitudinal lateral flanks joined together by a transverse back which includes an upper longitudinal part and a downwards-curved part at its rear end. The transverse back of the cover includes an aperture giving access to means for fixing the drive head onto the end of an alternating-sweep drive shaft. A cap is provided, the contour of which is complementary to that of the aperture, which is mounted articulated on the cover between a service position in which it blocks off the aperture and an open raised position in which the aperture is clear.

Abstract: An electric motor unit with continuous current containing a connection plate and a card that carries electronics for the control of the motor. The card also contains electronics to monitor the current in order to detect the blockage of the motor's rotor and electronics to control the power supply of the motor. The card and/or the plate carries devices to sense temperature. The electronics to control the power supply are linked to the device(s) sensing temperature, as well as to the electronics monitoring the current. The control electronics cuts off the power supply of the motor when blockage of the motor's rotor is detected and a temperature measured by at least one of the devices reaches a high threshold value and reestablishes the power supply of the motor when the temperature is at or below a low threshold value.
