Described herein are sensor assembly cleaning apparatuses and methods of operation thereof that utilize a fluid such as pressurized air to cause dispersion of debris, rain droplets/water droplets from other sources, condensation, or any other environmental contaminant that may obscure a transparent surface such as a glass window of a camera housing from the glass window. In this manner, the pressurized air acts to clean the transparent surface, and as a result, improve the clarity of the field-of-view provided through that transparent surface to a camera housed in the camera housing. In addition, sensor assembly cleaning apparatuses described herein can include a water nozzle that is adapted to eject high pressure water onto the transparent surface as well as towards an air nozzle or an air vent that is adapted to eject the pressurized air. The water nozzle can thus be used to remove debris form the air nozzle.

A sensor lens cleaning system for a cylindrical sensor having a sensor lens surface includes an extended member having a first end coupled to the cylindrical sensor and a second end opposite the first end, a nozzle coupled to the second end of the extended member, an actuator coupled to the extended member and configured to control the extended member, and a controller in electronic communication with the actuator and configured to communicate an actuator control signal to the actuator. The nozzle generates an air stream directed at the sensor lens surface.

This technology relates to system for clearing a sensor cover. The system may include a sprayer, a support, and a positioning device. The sprayer may be mounted to the support and direct a flow of fluid to the sensor cover. The positioning device may be configured to adjust the position of the sprayer on the support. The system may include a nozzle and the nozzle may be positioned to direct the flow of fluid to an area of the sensor cover. The system may include additional sprayers.

A cleaning device for selectively bombarding a surface with a media sequence, the sequence including at least a first gaseous medium and a second liquid medium, includes a nozzle configured to bombard the surface with the second medium; a cleaning valve with a holding port, a pressure port, a plunger, and a pressure outlet; and a high-pressure accumulator configured to store the first medium. The first medium is loaded with an accumulator pressure. The cleaning device further includes a changeover valve configured to selectively create a connection between a first medium supply line and a holding line connected to the holding port. The pressure outlet is configured to bombard the surface with the first medium in pulse-like fashion.

An air outlet of a side defroster is disposed on a front pillar of a vehicle, and includes upper vertical fins configured to direct a flow of air toward a side window, and lower vertical fins configured to direct a flow of air toward a fixed window disposed forward with respect to the side window.

Provided is an air cleaner for vehicles, configured so that objects to be cleaned can be easily maintained in as clean state. This fair cleaner (1) for vehicles is provided with: ejection openings (20, 30) for ejecting air toward the surfaces (21, 31) to be cleaned of objects (2, 3) to be cleaned and a non-positive displacement blower means (10) for continuously delivering air to the ejection openings (20, 30).
