A cleaning device for spray cleaning of a sensor surface includes a spray-body having a spray-nozzle and a body-housing. A liquid fluid connection to a liquid inlet and a pressurized air fluid connection to a pressurized air inlet are such that suction pressure is induced at the liquid fluid connection upon providing pressurized airflow from the pressurized air inlet to the spray-nozzle. A hydraulic flow path is connected to the liquid fluid connection. A hydraulic valve is adapted for selective control of supplying liquid fluid to the liquid fluid inlet. A pneumatic flow path is connected to the pressurized air fluid connection. A pneumatic valve is in a pressurized air fluid duct adapted for selective control of supplying pressurized air fluid from a pressurizer to the pressurized air fluid inlet. The spray-nozzle sprays the liquid fluid and the pressurized air fluid as a mixture in an aerosol jet.

The system also includes a wash system having a fluid reservoir and fluid level sensor, and a wiper system including a control unit (ECU) that is configured to operate the system based at least in part on the one or more configurable parameters, wherein the wiper system is coupled to the wash system and supplies the wash fluid to the wiper system. Also provided are embodiments of a method for performing dynamic control of the aircraft windscreen wiper and wash system configuration parameters.

An exemplary system for applying a water-repellent coating to the outside of a window of a vehicle includes at least one reservoir for a hydrophobic fluid, at least one wiper with a wiper blade, and a control device. A first line leads from the reservoir to the wiper. The first line extends at least over part of the length of the wiper and has, in the region of the wiper blade, at least one opening by way of which the hydrophobic fluid can be applied to the window. An exemplary method for applying a water-repellent coating to a window of a vehicle, includes, among other things, determining a status of the water-repellent properties of the window with reference to a threshold value of a quantity of water on the outer-facing surface of the window, transmitting a signal from the control device to initiate a communicating of a hydrophobic fluid from a reservoir to a wiper when the status indicates that the quantity of water on the window has reached the threshold value, communicating hydrophobic fluid from the reservoir to the wiper, distributing hydrophobic fluid on the window by means of a movement of the wiper.

The present invention relates to a fluid level sensor-attached motor pump for a washer fluid, in which a fluid level sensor for detecting the remaining amount of a washer fluid stored in a washer fluid reservoir and outputting a detection signal is integrally mounted to a motor pump for a washer fluid so that an operator can check the remaining amount of the washer fluid through a dashboard of a vehicle and thus can replenish an insufficient washer fluid, in which the fluid level sensor is integrally mounted to the motor pump for a washer fluid to solve a problem in that the motor pump and the fluid level sensor are separately wiring-connected to the washer fluid reservoir to thereby deteriorate workability of wiring so that workability of wiring can be increased and the wiring can be simplified to reduce a defective proportion, in which the motor pump for a washer fluid and the fluid level sensor are integrally manufactured so that the manufacturing cost can be reduced, and in which the fluid level sensor for detecting the remaining amount of a washer fluid and outputting a detection signal is manufactured by selecting any one of a combination of a magnet and a Hall sensor, a combination of a magnet and a reed switch, and a combination of a Hall sensor and a buoyancy device mounted with a magnet so that the improvement in performance can be achieved through the use of a magnetic Hall sensor having reliability.
