A Power Head assembly includes a motor having a rotating shaft and a converter configured to convert rotational motion of the shaft to reciprocating linear motion. The Power Head assembly also includes a weatherproof housing configured to house the motor and an inner portion of the converter. The Power Head assembly also includes a receptacle configured to receive a windshield arm of the vehicle and a fastener configured to attach an outer portion of the converter to a windshield wiper blade directly or indirectly, causing the windshield wiper blade to reciprocate along the windshield wiper blade. The Power Head assembly also includes a controller control the motor of the Power Head assembly.

A cleaning device for a surface, such as a windshield of a vehicle, includes an active positioning system and a cleaning head. The active positioning system is configured to deploy from a storage position hidden from view within a covered storage space and to position the cleaning head upon the windshield. The active positioning system includes a first extension member and a second extension member that move relative to one another to position the cleaning head, and also move the cleaning head across the windshield along a path. The cleaning head can have a brush portion configured to agitate debris from the window, and a drying portion configured to dry the window after cleaning. The cleaning device can be controlled via a touch-screen display in the vehicle, enabling a user to direct that specific portions of the windshield be cleaned as desired.

An electromagnetic wiper system for a windshield of a vehicle includes a linear actuator, a wiper-arrangement, and control circuitry. The linear actuator includes at least one guide rail having permanent magnets and an electromagnetic moving block. The electromagnetic moving block includes at least one perforation that surrounds the at least one guide rail and at least one electromagnetic coil that surrounds the at least one perforation. The wiper-arrangement includes a wiper arm and a wiper blade, wherein at least the wiper arm is coupled to the electromagnetic moving block. The control circuitry controls a linear motion of the electromagnetic moving block along the at least one guide rail to steer the wiper arm that is coupled to the electromagnetic moving block back and forth across a length of the windshield to the windshield, wherein the electromagnetic moving block induces minimal friction during the linear motion.

A flexible wiper blade is attached at each end to motor driven pivot points. When material needs to be cleared from the window surface, the motorized pivot points rotate in a controlled fashion to flex the wiper out into the window area sweeping debris away as the wiper moves. At the other end of motion, the wiper blade is again flexed mostly out of the clear aperture of the window but on the other side of the window's edge.

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 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.
