A self-contained, compact camera wash system 1000 for a drone 800 or as an automotive aftermarket kit 1101 uses a pressurized container 1002 similar to a common aerosol can to supply washer fluid to a washer nozzle 1020 via actuable valving. The fluid supply container is small for use with drone cameras (e.g., ˜15 ml in volume) and is readily packaged in a compact assembly. For the automotive aftermarket kit 1101 a larger volume container volume is provided and configured to be easily replaced as needed.

A sensing apparatus is provided. The sensing apparatus may include: a casing; a sensor assembly mounted in the casing; and a wiper assembly removing an outside material attached to the sensor assembly. The sensor assembly includes a sensor module and a sensor housing surrounding the sensor module, and the sensor housing is made of a transparent material. The sensor housing is rotatably mounted in the casing. The sensor housing is rotatably supported with respect to a hollow shaft in the casing, and the hollow shaft is mounted in the casing.

A vehicle may have a vehicle body and one or more movable sensors mounted to the body. A movable sensor may be rotated, linearly translated, or otherwise moved between multiple positions in response to location information, driving mode information, vehicle speed, and/or other information. The movable sensor may be moved to track objects, to provide pedestrians and others with visual feedback, to allow the sensor to gather desired sensor information to support driver assistance and autonomous driving operations, to place the sensor in a stowed position, and to perform other functions. The movable sensor may be protected with a movable cover. A cleaner may clean the sensor. The sensor may be a radar sensor, lidar sensor, camera, or other sensor. Information from the sensor may be used to detect roadway obstructions, to detect objects near the vehicle, to monitor pedestrians, and to monitor other conditions.

A cleaning device according to an embodiment is a cleaning device that cleans a light transmission member provided on a camera. The cleaning device includes a filamentary member configured to contact the light transmission member and a rotation member configured to rotate the filamentary member such that the filamentary member moves along the surface of the light transmission member with the filamentary member in contact with the light transmission member.

A tractor trailer roof heater apparatus for preventing snow and ice accumulation includes a reservoir configured to hold heater oil within an inner cavity and configured to be coupled to a tractor trailer. A heater is coupled to a bottom side of the reservoir within the inner cavity and is configured to heat the heater oil. A pump is coupled to a top side of the reservoir and has a draw tube extending through a pump aperture into the inner cavity to draw the heater oil from the reservoir and push it through an outlet aperture through an oil tube. The oil tube is configured to be coupled within a roof of the tractor trailer to carry hot heater oil from the pump and then return the heater oil to the reservoir. A power supply is coupled to the pump and a thermostat is coupled to the reservoir.
