Abstract: Provided herein is a system and method for a sensor housing that mitigates glare within the field-of-view and facilitates cleaning of a sensor lens. A sensor assembly may include: a sensor having a sensor lens and a field-of-view through the sensor lens; and a baffle defining a sensor lens aperture, where the field-of-view through the sensor lens is through the sensor lens aperture, where the baffle includes a series of concentric rings extending away from the sensor lens aperture and increasing in diameter as a distance from the sensor lens aperture increases. According to some embodiments, the series of concentric rings defines a viewing angle, where the viewing angle corresponds to the field-of-view of the sensor lens.

Abstract: A system comprises a microphone array and a processor. The microphone array detects first sound signal and the second sound signal. Each of the first and second sound signals has a particular frequency band. Each of the first and second sound signals is originated from a particular sound source. The processor receives the first and second sound signals. The processor amplifies the first sound signals, each with a different amplification order. The processor disregards the second sound signal, where the second sound signal includes interference noise signals. The processor determines that the first sound signals indicate that a vehicle is within a threshold distance from an autonomous vehicle and traveling in a direction toward the autonomous vehicle. In response, the processor instructs the autonomous vehicle to perform a minimal risk condition operation. The minimal risk condition operation includes pulling over or stopping the autonomous vehicle.

Abstract: Techniques are described for compensating for movements of sensors. A method includes receiving two sets of sensor data from two sets of sensors, where a first set of sensors are located on a roof of a cab of a semi-trailer truck and a second set of sensor data are located on a hood of the semi-trailer truck. The method also receives from a height sensor a measured value indicative of a height of the rear of a rear portion of the cab of the semi-trailer truck relative to a chassis of the semi-trailer truck, determines two correction values, one for each of the two sets of sensor data, and compensates for the movement of the two sets of sensors by generating two sets of compensated sensor data. The two sets of compensated sensor data are generated by adjusting the two sets of sensor data based on the two correction values.
