A vehicle wiper system includes a drive mechanism, a wiper and a gutter each connected to the drive mechanism, and a locking mechanism. The wiper has a stowed position and an extended position. The drive mechanism reciprocally moves the wiper about a pivot axis to sweep a defined area of a windshield. The drive mechanism moves the gutter together with the wiper about the pivot axis between a stowed position and a deployed position wherein the gutter extends along a lateral edge of the windshield. The locking mechanism is configured to lock the gutter in the deployed position allowing the gutter to be statically disposed at the deployed position while the wiper is reciprocally moved about the pivot axis.

A wiper control technique is provided that can prevent a windshield from being damaged by a falling wiper blade during a wiper parking operation, even when a wiper arm is in a retreat position where the blade is raised and held away from the windshield. In one embodiment, the wiper arm is stopped for a predetermined time interval at a predetermined pause position when the wiper arm is positioned above a parked position and at the retreat position during the wiper parking operation, while the wiper arm is being swung downward toward a lower reversal position. The pause position is a position at which the wiper arm is able to fall toward the windshield to return to a base position. After a lapse of the predetermined time interval, the wiper arm is swung to the parked position.

A working vehicle includes an engine mounted in a front portion of a travelling vehicle, and a post-processing device configured to purify exhaust gas from the engine. The engine and the post-processing device are covered with a hood. An upper surface side of the hood is inclined to extend diagonally upward from a front side to a rear side. The post-processing device is mounted on an upper side of the engine, and is positioned on a rear and inner side of the inclined upper surface side of the hood.

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.

This disclosure relates to techniques for implementing a windshield wiper system with an actively movable platform. The windshield wiper system can include a windshield wiper arm mechanically coupled to a platform and an actuator mechanically coupled to the platform. The windshield wiper arm can be configured to move through a planar range of motion that is substantially parallel to a surface of a vehicle when the platform is positioned at a first spatial location and the movable windshield wiper arm can be configured constrained from moving through the planar range when the platform is positioned at a second spatial location.

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 vehicular cowl louver assembly, a vehicular windshield assembly and a vehicle. A cowl louver that makes up a portion of the vehicular cowl louver assembly has one or more recesses formed in an upper-facing surface with which to provide storage of an ice scraper. A resiliently-biased clip allows the ice scraper to be selectively removable from the cowl louver to enable a person to scrape ice, snow or other debris from a vehicular windshield. The ice scraper may be returned to the recess after use, where the clip keeps the two secured to one another, even during vehicular movement. In one form, the surface of the ice scraper may be made to form a substantially flush, continuous fit with the portion of the surface of the cowl louver that is adjacent the recess to improve aerodynamic and aesthetic features of the cowl louver assembly.
