A self-centering wiper system for an optical device having an optical device body defined by an outer surface with an annular-shaped cross-section disposed along an axis includes an annular-shaped bellows. The bellows is configured to fit externally and concentrically with respect to the outer surface of the optical device body. The bellows has at least one bladder configured to accept a pressurized fluid to thereby extend the annular-shaped bellows along the axis. The wiper system also includes an annular-shaped wiper element fixed to the annular-shaped bellows and configured to wipe contaminants off the outer surface of the optical device body as the at least one bladder accepts the pressurized fluid and the annular-shaped bellows expands along the axis. An optical device having such a self-centering wiper system is also disclosed.

A wiper system for wiping off deposits deposited on a surface of a wiped member comprising a pair of carriages attached to frame members holding the wiped member so as to face each other across the wiped member and moving back and forth over the frame members along two facing sides of the wiped member, a pair of wiper arms respectively attached to the pair of carriages and extending from the frame member sides to the wiped member sides, and a pair of wiper blades respectively attached to the pair of wiper arms, extending substantially parallel to the other two facing sides of the wiped member, and arranged at the surface of the wiped member.

A cleaning device for a vehicle has tracks above and below the vehicle's windshield. A brush, wiper blade and spray bar extend across the windshield at a starting side of the windshield. The spray bar provides washer fluid as the brush rotates against the windshield. The spray bar, rotating brush and wiper bar are moved along the tracks and across the windshield to an opposing, return side of the windshield where the wiper blade first contacts the windshield and the brush stops rotating and moves away from the windshield. The spray bar rotates next to the wiper blade to blow air against the windshield. The wiper blade scrapes water while air blows water off the windshield as they move back to the starting side of the windshield where they are stored in a frame along the side of the windshield when not in use.

A brushing system, including: a brush; and a hydraulic motor, for rotating the brush. The hydraulic motor is operable by pressurized water, and the pressurized water is administrable by outlets of the brush, thereby brushing of the brush is accompanied by the administrable water.

The technology relates to a system for cleating a sensor cover. The system may comprise a wiper comprising a wiper support, a wiper blade, and a sensor cover. The wiper blade may be configured to clear the sensor cover of debris, and the sensor cover may be configured to house one or more sensors. A wiper motor may rotate the wiper and a sensor motor may rotate the sensor cover. The system wiper blade may comprise a first edge attached to the wiper support and a second edge which may be configured to be in contact with the sensor cover. The wiper blade may extend in a corkscrew shape around the wiper support. The wiper motor may be configured to rotate the wiper in a first direction and the sensor motor may be configured to rotate the sensor cover in a second direction opposite the first direction.

A windshield wiper system (3) for vehicles. A windshield (1) has a curved surface. The system (3) comprises two wiper arms (14) and one wiper blade (5), one of said two wiper arms (14) being mounted to said oscillating gear drive (2), said wiper blade (5) being mounted by means of said two wiper arms (14) distal to said oscillating gear drive (2) for oscillation across the windshield (1). Said two wiper arms (14) have each along said curved surface of the windshield (1) a respectively pivotal wiper arm axis (8). At least one cranked fitting (16) and a prolongation fitting (7) are provided, said wiper blade (5) being mounted rotatable about a wiper blade rotation axis (9) by means of said wiper blade holder (21) and said wiper blade fit bolt (22) to said prolongation fitting (7). Said prolongation fitting (7) is mounted rotatable about prolongation fitting rotation axes (18). Said prolongation fitting rotation axes (18) is inclined to said respective wiper arm axis of each of the two wiper arms (14) by an angle 45<<135.
