Abstract: A mounting device includes an elongated beam having a first end portion, a second end portion, and a side surface extending between the first end portion and the second end portion. The mounting device also includes a first camera mount attached to the first end portion configured to support a first camera, a second camera mount attached to the second end portion configured to support a second camera, and a bracket for fixedly connecting the elongated beam to a vehicle. The bracket is positioned between the first end portion and the second end portion. The bracket includes at least one base configured to be attached to the vehicle and a wall extending from the at least one base comprising an opening sized to receive the elongated beam, such that engagement between the wall and the elongated beam restricts rotation of the elongated beam about multiple axes.

Abstract: A vehicle sensing system may include a housing for containing sensor electronics, the housing having at least one window being aligned with at least one of the sensor electronics within the housing, a fan arranged on the housing and configured to provide airflow through the housing, and a conditioning element having a plurality of fins forming configured to receive the airflow from the fan to cool the sensor electronics and to direct warmed air from the fins onto the window to provide the warmed air to the window.

Abstract: A method of operating a vehicle having a roof-mounted sensor apparatus includes, by a retractable sensor, capturing data about an environment along a path on which the vehicle is traveling. The method includes, by a location sensor, determining a location of the vehicle along the path. By a computing device of the vehicle, the method includes accessing a map that corresponds to the location and the path, determining that a structure having a minimum clearance is ahead at an imminent location on the path, and determining that the minimum clearance is less than or equal to an elevation of the retractable sensor. The method includes prior to the vehicle arriving at the imminent location, automatically operating a lifting element of the sensor apparatus to withdraw the retractable sensor into the sensor apparatus so that the elevation of the retractable sensor is less than the minimum clearance of the structure.
