An air blowing device of the present disclosure has a wall portion, a duct, a guide wall, and an airflow forming mechanism. The wall portion is provided with an opening periphery providing a blow outlet. The duct communicates with the blow outlet. The guide wall is provided in an inner wall of a downstream portion of the duct and has a wall surface having a shape protruding toward an inside of the duct. The airflow forming mechanism forms a flow of air along the guide wall such that the air flowing through the duct is blown out of the blow outlet while being bent along the guide wall. The opening periphery has a portion that communicates with a downstream side of the guide wall and that has a shape protruding in a blowing direction of the air, which is bent along the guide wall from the blow outlet.

A coating composition for imparting a hydrophobic film on a target surface is provided that includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade.

A method for preventing vehicle windscreen fogging or re-freezing includes calculating a windscreen interior surface dew point temperature value and/or windscreen interior surface fogging and/or exterior surface re-freezing probability value, and providing only a sufficient conditioned airflow to the windscreen to prevent the calculated probability value from exceeding a predetermined fogging and/or re-freezing risk threshold value. One or more controllers perform the calculating, and actuate elements of a vehicle HVAC system to provide only a sufficient conditioned airflow to cause a windscreen interior surface temperature value to exceed the windscreen interior surface dew point temperature value or to cause a windscreen exterior surface temperature value to exceed a windscreen exterior surface freezing temperature. Inputs influencing the windscreen interior surface fogging and/or exterior surface re-freezing probability value and/or the windscreen direct dew point temperature value are used to adjust the threshold values. Systems for accomplishing the described methods are provided.

Vehicle cab windscreen air distribution system for a windscreen (1) provided with an external windscreen wiper (5) and a windscreen wiper motor (2a) mounted on the inside of the windscreen. The distribution system comprises an air distribution housing (3) which at least partially surrounds the wiper motor (2, 2a), the housing defining a passage (3a) for the supply of air onto the windscreen (1a) in the vicinity of the motor. The passage (3a) for the supply of air is defined between a motor housing (2) and part of the air distribution housing (3),

A roof module for forming a vehicle roof on a motor vehicle, the roof module may have a panel component whose outer surface at least partially forms the roof skin of the vehicle roof, the roof module having at least one environment sensor configured to send and/or receive electromagnetic signals for detecting the vehicle environment. At least one reflector element at which the electromagnetic signals can be reflected is associated with the environment sensor.

A composite pane having an electrically heatable coating is described. The composite pane comprises: at least two individual panes; an intermediate layer, which connects the individual panes to one another; at least one transparent, electrically conductive coating on at least one side of at least one of the at least two individual panes, the at least one side faces the intermediate layer; and at least two bus bars, which are connected to the at least one transparent, electrically conductive coating, wherein a first bus bar is electrically connected to a first feed line provided for connection to one pole of a voltage source and a second bus bar is electrically connected to a second feed line provided for connection to the second pole of the voltage source.

An HVAC device including a compressor and a first blower disposed along ventilation pipes for taking in interior air of the vehicle through a duct in communication with the first blower. An evaporator and dehumidifying member may be disposed along the ventilation pipes and in communication with the first blower. The device includes a condenser and an electrical heating unit disposed along the ventilation pipes and in communication with the first blower, and a vehicle interior air reflux duct disposed along the ventilation pipes and in communication with first blower and the interior of the vehicle. A second blower disposed along the ventilation pipes for taking in air outside of the vehicle through another duct, and a first exhaust duct and a second exhaust duct disposed along the ventilation pipes and in communication with the second blower. The device includes several modes for creating different flow paths through the vehicle.

Systems and methods for self-cleaning a surface of an object where an electrodynamic shield is mounted to a surface of the object. The electrodynamic shield includes one or more sets of electrodes atop a substrate, at least one or more sets of electrodes being covered in a protective film. A coating is applied to the top surface of the protection film. A signal pulse generator is connected to the one or more sets of electrodes. The signal pulse generator generates a pulse signal that causes the one or more sets of electrodes to generate an electric field. The pulse signal comprises a plurality of different pulse signals which have phase differences between consecutive signals, and the electric field causes a particle atop the coating to experience an electrostatic force and be repelled away from the coating. These pulse signals (including shapes, amplitudes, shifts, and frequencies) can be tuned to increase efficiency of removal depending on dust type and relative humidity.
