A medium distributing assembly for a vehicle design element includes a medium guide including at least one medium receiving element; and at least one medium exit element, where the medium exit element has at least partly an annular form.

An optical unit includes an optical sensor, a protective cover disposed in a direction of view from the optical sensor, an actuator to drive the protective cover, and a casing including a space between the casing and the protective cover and to which the optical sensor and the protective cover are attached. A first region on the casing adjacent to an outer edge of the protective cover with the space interposed between the casing and the outer edge of the protective cover is a hydrophobic region where a contact angle of a droplet is equal to or larger than a predetermined angle.

In a cleaning device, a signal processing circuit determines that a foreign substance has adhered to a surface of a protection cover based on at least two pieces of information among a change amount of a resonant frequency when a vibration portion is driven at a first voltage, a change amount of a current value relating to an impedance detected by an impedance detector, and a temporal change of an image captured by an imaging portion, and cleans the surface of the protection cover by controlling the vibration portion in accordance with the determination.

An optical device includes a protective cover disposed in a field of view direction of an optical sensor, a casing that holds the protective cover, a temperature adjuster that adjusts the temperature of the protective cover, and a vibrating body that drives the protective cover to remove foreign matter adhering to a surface of the protective cover. The temperature adjuster adjusts the temperature of the protective cover so that the temperature increases from the periphery to the center of the protective cover.

An optical device includes a protective cover, a housing, and a vibrating body that vibrates the protective cover by selecting, from multiple vibration modes in which the protective cover is vibrated, a cleaning mode in which vibration displacement of the protective cover becomes maximum and a higher-order heating mode in which the number of nodes is larger than that in the cleaning mode. In the heating mode, the position of the maximum vibration displacement in this vibration mode is within a region of the protective cover that corresponds to the field of view of the optical sensor.

The present invention for rights for a system configured for use with an existing motor vehicle windshield washer system whereby a portion of solution is directed to a headlamp washing outlet.

A wireless vehicle light washing system that is activated by a remote controller to enable washer fluid spray nozzles to spray/wash external lights of a semitrailer or other commercial vehicle from within a cab of the semitruck or other commercial vehicle. The wireless vehicle light washing system can be wirelessly activated to independently control the washer fluid spray nozzles fixed to the semitrailer or other commercial vehicle as desired.

One general aspect includes a system having one or more heat pads installed at a vehicle, the one or more heat pads configured to provide infrared energy transmissions to a vehicle component to defrost, defog, or both defrost and defog a surface of the vehicle component. The system may also carry out the following steps: (a) determining that ice or fog or both ice and fog has accumulated on the surface of the vehicle component; and (b) based on the determination made in step (a), activating the one or more heat pads to defrost, defog, or both defrost and defog a surface of the vehicle component.
