Abstract: A sensor unit includes a sensor interface and a host interface. The sensor interface can be coupled to a number of sensors mounted on various locations of the ADV. The host interface can be coupled to a host system that is configured to perceive a driving environment surrounding the ADV based on sensor data obtained from the sensors and to plan a path to autonomously drive the ADV. The sensor unit further includes a sensor processing module and a sensor control module coupled to the sensor interface, and a time module coupled to the sensor processing module and the sensor control module. The sensor processing module is configured to process sensor data received from the sensors via the sensor interface. The sensor control module is configured to control operations of the sensors. The time module is configured to generate time to synchronize timing of the operations of the sensors.

Abstract: According to some embodiments, before an M.2 compatible module or device is mounted onto a data processing system that operates an autonomous driving vehicle (ADV), the M.2 module is placed onto a tray device to increase the stiffness of the M.2 module. The tray device containing the M.2 module is then mounted on a board or motherboard of the data processing system. Since the M.2 module is placed on the tray device, the overall stiffness has been significantly increased, which can sustain the physical impact on the M.2 module due to the physical movement and oscillation during the autonomous driving of the ADV. In addition, the tray device also provides suspension effect on the M.2 module during the movement of the ADV. As a result, the M.2 module would not easily damaged during the autonomous driving.

Abstract: A data center system includes a container to contain electronic racks of IT components operating therein, a cooling unit disposed underneath the electronic racks to receive cool liquid from a chiller unit, to exchange heat generated from the IT components, and to transmit the hot liquid carrying the exchanged heat back to the chiller unit. Each electronic rack includes a housing to house IT components arranged in a stack, a first rack aisle formed on a first side of the IT components to direct cool air received from the cooling unit upwardly, and a second rack aisle formed on a second side of the IT components to direct hot air to the cooling unit downwardly, where the host air is transformed from the cool air from the first rack aisle by flowing through an air space between the IT components.
