A vehicular camera module includes a housing, a camera disposed in the housing, and a transparent cover mounted at the housing. The camera views through the transparent cover. A wiper element is movable relative to the transparent cover to clean the transparent cover. The wiper element is moved via operation of a hydraulic actuator. With the vehicular camera module mounted at an exterior portion of a vehicle, the camera views through the transparent cover in order to capture image data of a scene exterior of the vehicle. With the vehicular camera module mounted at the exterior portion of the vehicle, the hydraulic actuator operates via pressurized fluid supplied to hydraulic actuator to move the wiper element back and forth across the transparent cover to clean the transparent cover of the vehicular camera module.

The present invention relates to a motor vehicle's windscreen wiper, that includes a wiper blade and driving system; where the driving system includes a wiper motor, a wheel plate that pivots about a central rotational axis; where the wheel plate's angular position is associated with the wiper blade's angular position; where a parking cam on the wheel is associated with two parking contact springs with parking electrodes that press against the wheel plate surface under a resilient bias of the parking contact spring; where a parking trace is defined by a track slid by the parking electrode on the wheel plate during the wheel plate's rotation such that distances between the contact spring parking electrodes and the wheel plate's central rotation axis is substantially equal to each other such that traces of the parking electrodes generally coincide with each other; where the invention further includes a single-trace parking cam consisting of only one arc-segment such that the parking trace substantially follows a center arc by; where application of the single-trace cam is able to achieve the wiper parking function of the windscreen wiper in a compact and cost-effective manner.

A windshield wiper system for an aircraft is provided and includes a motor, an output shaft, a wrap spring and crank rocker mechanism (WSCRM) to which the motor and the output shaft are coupled and a controller. By way of the WSCRM, first directional rotation input to the WSCRM from the motor via a two-stage gear reduction is converted such that the output shaft drives wiper blade oscillation through a first sweep angle and second directional rotation input to the WSCRM from the motor is converted such that the output shaft drives wiper blade oscillation through a second sweep angle. The controller is configured to control the motor such that the first directional rotation is continuously or non-continuously input during first or second flight conditions, respectively, and the second directional rotation is continuously input during third flight conditions.

An extendable windshield wiper system includes a wiper blade assembly having: a resilient material wiper blade; and a wiper extension rod connected to the wiper blade. A wiper sleeve is configured to move about an arc of rotation with respect to an axis of rotation of the wiper sleeve. A bore of the wiper sleeve has the wiper extension rod slidably disposed within the bore. An actuation portion directs a pressurized fluid to outwardly extend the wiper extension rod from the wiper sleeve and thereby to outwardly extend the wiper blade in an extension direction during a first portion of the arc of rotation. The wiper blade is induced to traverse an extended arc of travel during rotation of the wiper extension rod and the wiper sleeve along the arc of rotation.
