Abstract: An assembly includes a housing. The assembly includes a sensor supported by the housing. The assembly includes a shell enclosing the sensor and rotatable relative to the housing in a first direction, the shell defining a window. The assembly includes a deflector extending radially outward from the shell at a leading edge of the window.

Abstract: An assembly includes a housing and a sensor supported by the housing. The assembly includes a deflector supported by the housing forward of the sensor. The deflector and the sensor define a spacing therebetween. The spacing is open to an ambient environment external of the housing. The deflector includes transparent material that permits light to pass through the deflector.

Abstract: A sensor apparatus includes a cylindrical sensor window defining an axis oriented vertically and a ramp. The sensor window includes an exterior surface facing radially outward relative to the axis. The ramp is on the exterior surface of the sensor window. The ramp includes a leading surface and a trailing surface. The leading surface and the trailing surface are elongated parallel to the axis.

Abstract: A vehicle includes a windshield having a top edge. The vehicle includes a roof extending rearward from the top edge of the windshield. The vehicle includes a sensor assembly supported by the roof, the sensor assembly including at least one of a LIDAR sensor or a camera. The vehicle includes a deflector movable from a lowered position to a raised position and supported by the roof at the top edge of the windshield forward of and spaced from the sensor assembly.

Abstract: A sensor apparatus includes a sensor including a sensor lens, an air nozzle fixed relative to the sensor lens and positioned to direct airflow out of the air nozzle across the sensor lens, and a fin positioned inside the air nozzle. The fin is rotatably coupled to the air nozzle and rotatable relative to the air nozzle around an axis of rotation. The fin is elongated radially from the axis of rotation. The fin is rotatable between a first position impeding airflow through the air nozzle and a second position permitting airflow through the air nozzle.
