A windshield wiper system for use on an aircraft includes a controller and a wiper assembly including a wiper arm, a wiper blade, and a moving block. Further, the windshield wiper system includes a rail assembly including a rail assembly rack, a plurality of electromagnets, and an electrical interface. The electrical interface and the plurality of electromagnets induce a force on the moving block of the wiper assembly, causing the wiper assembly to sweep across the windshield of the aircraft. The controller is coupled to the rail assembly and the controller is configured to direct the motion of the wiper assembly through command signals to the rail assembly.

A mirror cleaning system, an improved mirror for a vehicle having the system installed thereto, and a method of cleaning the improved mirror using the system. The system includes a housing attachable to a vehicle side mirror, a heating element operably connected to a power source, a wiper, and a spray nozzle fluidly connected to a cleaning fluid source. The system is designed to de-ice and de-frost the improved mirror, spray cleaning fluid thereon, and wipe debris and fluids to improve driver visibility.

A system includes a dome, a wiper assembly, a position sensor and a control device. The wiper assembly includes a wiper blade configured to rotate around the dome. The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.

The technology relates to a wiper systems. For instance, a system may include a sensor including a sensor housing and a housing window in the sensor housing. The system may also include a rotating drive mechanism. A first portion of the rotating drive mechanism is positioned adjacent to a top of the housing window. The system also includes a plurality of pulleys, and the rotating drive mechanism may be wrapped around at least a portion of the pulleys. The system also includes a wiper attached to the rotating drive mechanism and a motor. The motor may be configured to rotate at least one of the pulleys in order to cause at least the first portion of the rotating drive mechanism to rotate in a first direction. As a result, the wiper may move across the housing window from an initial position to a second position in order to move contaminants on the housing window.

A cleaning device for a surface, such as a windshield of a vehicle, has a housing that holds a spray bar, rotatable brush and a wiper blade. An engagement mechanism moves spray bar, the brush, and the wiper blade out from a disengaged position within the housing to an engaged position outside the housing so that they can be used to clean, brush, and dry the surface. After the spray bar, brush, and wiper blade are used to, respectively, clean, brush, and dry the surface, the engagement mechanism then moves the spray bar, the brush, and the wiper blade to a disengaged position within the housing.

An autonomous vehicle includes a front bumper comprising an opening; a light detection and ranging (LiDAR) sensor comprising a surface exposed to the opening of the front bumper; and a sensor cleaning device configured to remove foreign materials on the surface. The sensor cleaning device includes a wiper configured to move over a surface of a sensor to remove foreign materials from the surface of the sensor; and a movement unit connected to the wiper and comprising at least a linkage system configured to perform folding and unfolding movements, which causes the wiper to reciprocate over the surface of the sensor.

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.

A wiper device for a small and curved surface such as a spherical surface of an optical element includes at least one elongate wiper element with two ends, two drive units to which the ends of the wiper element are attached so that the wiper element can be moved on the surface of the optical element using the two drive units, and at least one contacting means for bringing the wiper element into contact with a surface of the optical element, the contacting means shapes the wiper element around at least that part of the surface which is exposed to the environment due to an opening provided by the housing and is to be cleaned.

Provided is a bearing device capable of suppressing corrosion for a long time. The bearing device is for use in a wiper arm to pivotably attach a retainer to an arm head. The bearing device includes an outer bushing press-fitted into a hinge portion of the arm head, an inner bushing rotatably inserted into a bore in the outer bushing, and a rivet inserted into a bore in the inner bushing to secure the retainer and the inner bushing together integrally. Thus, a hinge portion of the retainer, the inner bushing, and the rivet are pivotable relative to the hinge portion of the arm head and the outer bushing. The outer bushing has an inside bushing part and an outside bushing part provided around the outer periphery of the inside bushing part and joined to the inside bushing part. The joint surface of the inside bushing part and the joint surface of the outside bushing part are joined to each other by interatomic bonding. The outside bushing part is formed of the same material as that of the arm head.

A windshield wiper system (100) includes a pivoting wiper arm (110); a wiper blade (120) for wiping a surface (102); and a connector assembly (128) coupling the pivoting wiper arm (110) to the wiper blade (120), the connector assembly (128) comprising a gear drive (130) including at least one drive gear (132) and at least one positioning cog (136), wherein the gear drive (130) rotates the wiper blade (120) based on an angular position of the pivoting wiper arm (110) such that an arc of a motion path (320) of the wiper blade (120) is reduced.
