Abstract: An assembly is described. An assembly can include a housing comprising a first compartment and a plurality of vents letting air flow into and out. The assembly can further include a first ECU positioned within the first compartment, the first ECU comprising a first inlet letting air flow into the first ECU. The assembly can further include a second ECU positioned within the first compartment, the second ECU comprising a second inlet letting air flow into the second ECU. The assembly can further include a first plenum positioned between the first ECU and the second ECU and comprising a second compartment. The assembly can further include a first air duct forming a first channel letting air from a first vent of the plurality of vents into the second compartment, wherein the first plenum further comprises a second vent positioned to align with the first inlet of the first ECU.

Abstract: An integrated sensor assembly is described. The integrated sensor assembly can include a housing comprising a compartment. The housing can be arranged on a side surface of a cabin of an autonomous vehicle and within a threshold distance of a cabin roof of the autonomous vehicle. The assembly can include a first sensor arranged in the compartment, the first sensor configured to receive a first signal from a vehicle computer and collect information for mapping an environment of the autonomous vehicle. The assembly can include a light source arranged in the compartment. The light source configured to receive a second signal from the vehicle computer and emit a light pattern for visually indicating one of a hazard, a turn, or an autonomous mode. The light source can be arranged in the compartment to emit light to traffic toward a rear of the autonomous vehicle.
