Abstract: A system includes a camera housing and a control device associated with an autonomous vehicle. The camera housing houses a camera, and is mounted to an autonomous vehicle. The camera housing comprises a glass positioned in front of the camera. The glass is coated with a set of materials comprising a hydrophobic material and an anti-reflective material. The set of materials is configured to reduce ghosting effect on an image captured by the camera. The camera housing further comprises a top portion and a bottom portion. The top portion extends beyond the bottom portion to form a tilt angle. The tilt angle is configured to reduce indirect light from coming into a field of view of the camera. The processor facilitates autonomous driving of the autonomous vehicle using at least the image. The ghosting effect is reduced in the image due to using the set of materials.

Abstract: A method for controlling an autonomous vehicle includes collecting data about a surrounding of the autonomous vehicle, the data including global information of where the autonomous vehicle is positioned; deriving, at least in part based on the collected data, a perceived environment based on localizing the global information; determining a driving condition of the autonomous vehicle based on the perceived environment; modifying, according to the determined driving condition, a first configuration parameter of a sensor to adjust an amount of output data from the sensor; and simultaneously adjusting, according to the determined driving condition, a second configuration parameter for processing the output data to allow consistent data capturing and processing of the output data. A control system can employ such a method, and an autonomous vehicle can utilize such a control system.

Abstract: Devices, systems, and methods for hardware-based time synchronization for heterogenous sensors are described. An example method includes generating a plurality of input trigger pulses having a nominal pulse-per-second (PPS) rate, generating, based on timing information derived from the plurality of input trigger pulses, a plurality of output trigger pulses, and transmitting the plurality of output trigger pulses to a sensor of a plurality of sensors, wherein a frequency of the plurality of output trigger pulses corresponds to a target operating frequency of the sensor, wherein, in a case that a navigation system coupled to the synchronization unit is functioning correctly, the plurality of input trigger pulses is generated based on a nominal PPS signal from the navigation unit, and wherein, in a case that the navigation system is not functioning correctly, the plurality of input trigger pulses is generated based on a simulated clock source of the synchronization unit.
