Abstract: A Lidar system, window of the Lidar system and a method of moving a fluid along a window. The window includes a first electrode disposed on a first side of a outermost layer of the window, a second electrode disposed on the first side of the outermost layer, and a processor. The processor is configured to activate the first electrode to draw a fluid to a first location on a second side of the outermost layer opposite the first electrode, deactivate the first electrode, and activate the second electrode to draw the fluid to a second location on the second side of the outermost layer opposite the second electrode.

Abstract: A sensor assembly includes a sensor and a cover disposed adjacent to the sensor to protect the sensor. The cover has an inner cover surface and an outer cover surface opposite the inner cover surface. The inner cover surface faces the sensor, and the outer cover surface faces away from the sensor. The cover has a first end wall and a second end wall apart from the first end wall along a first direction. The sensor assembly includes a cleaning system having a wiper movable along the outer cover surface of the cover in the first direction to clean to the outer cover surface. The wiper is at least partly made of a wiper material, and the wiper material includes a hydrophilic material to facilitate removal of water from the outer cover surface of the cover.
