A motor-powered windshield scourer for any type of a motor-powered vehicle and or motor craft. The motorized windshield scourer may have a motor propelled appendages or a singular appendage that have replaceable scouring attachments joined to the appendages. The motor that propels the appendages can be positioned anywhere on or in the motor vehicle/craft, whether under the hood, in the cabin or elsewhere. The motor driven appendages with joined scouring attachments may be mounted on the windshield of the vehicle directly opposite of the windshield wiper blades. When turned on, the motor may move the appendages with joined attachments in a side to side and/or up and down motion across the windshield. The appendages may include an unpliable metal such as: steel, titanium, tungsten, or inconel, and the scouring attachments may include nylon scouring pads or a vinyl coated mesh attached to and covering rubber or foam.

A droplet sensor system is configured to detect the presence of droplets or other foreign bodies on the surface of a window. The sensor system emits light rays that are coupled into the window, where the window serves as a waveguide that guides the confined electromagnetic radiation across the window. Foreign bodies present on the surface of the glass outcouples a subset of the light as it propagates across the window, attenuating the power of outcoupled light measured at a photodetector mounted near an edge of the window. The system initiates a notification or a control action in response to detecting this attenuation of power due to outcoupling of the propagating light by foreign bodies.

A wiper device is provided. An operating range of each of two sets of wiper arm units can be properly restricted. A first wiper arm unit is prevented from colliding with a first front pillar or a dash panel when a first output shaft of a first speed reduction mechanism has rotated beyond a first control angle, and a second wiper arm unit is prevented from colliding with a second front pillar or the dash panel when a second output shaft of a second speed reduction mechanism has rotated beyond a second control angle.

A cleaner includes a high-pressure air generation unit and a nozzle. The high-pressure air generation unit includes a cylinder, a piston supported to the cylinder to be freely moveable and deliver the high-pressure air toward the nozzle, an urging spring urges the piston, and a movement mechanism which moves the piston to a predetermined position. The movement mechanism comprises a worm which rotate by a driving unit, and a worm wheel meshed with the worm and which rotate in association with rotation of the worm. The worm wheel comprises a pinion having gear teeth protruding from an outer periphery thereof. The piston is coupled with a rack having rack teeth which mesh with the gear teeth, and wherein an interval between each gear tooth of the gear teeth and one adjacent gear tooth is different from an interval between each gear tooth and the other adjacent gear tooth.

An imaging device for a vehicle and a vehicle are disclosed. The imaging device includes: a casing, a camera, a wiping member, and a drive device. The casing includes a casing body and a transparent cover disposed to the casing body, and the transparent cover is rotatable relative to the casing body. The camera is disposed in the casing and configured to obtain image information outside the transparent cover through the transparent cover. The wiping member is disposed to the casing and is stationary relative to the camera. The drive device is connected with the transparent cover and configured to drive the transparent cover to rotate to enable the wiping member to wipe an outer surface of the transparent cover.

A windshield wiper installation system is configured to be used to install a wiper on a windshield of an aircraft. The windshield wiper installation system includes a housing, an installation control unit contained within the housing, at least one positioning member secured to the housing, wherein the installation control unit is operatively coupled to the positioning member(s), and at least one position-setting member secured to the housing, wherein the installation control unit is operatively coupled to the position-setting member(s). The positioning member(s) is configured to be engaged to move the wiper to one or more desired positions on the windshield. The position-setting member is configured to set the desired position(s) when the wiper is at the desired position(s).

A wiping device for wiping an optical element clean of water or of particles includes a housing and a wiping element able to undergo a movement with respect to the housing, where the wiping device is configured to move in such a manner that such movement is caused by coupling a first unit in or on the wiping element with a second unit in the housing via a time-variable electromagnetic field. The wiping device may be used for wiping the surface of a lens or of a window, which lens or window is transmissive to visible light, ultraviolet radiation, and/or infrared radiation, and is preferably placed in front or as part of a camera. In addition, a rear view device or driver assistant device for use in or on a vehicle including such a wiping device, and a method for wiping an optical element are provided.
