Abstract: In one embodiment, an emergency vehicle detection system can be provided in the ADV travelling on a road to detect the presence of an emergency vehicle in a surrounding environment of the ADV using both audio data and visual data. The emergency vehicle detection system can use a trained neutral network to independently generate a detection result from the audio data, and use another trained network to independently generate another detection result from the visual data. The emergency vehicle detection system can fuse the two detection results to determine the position and moving direction of the emergency vehicle. The ADV can take appropriate actions in response to the position and moving direction of the emergency vehicle.

Abstract: The present application provides an optical information collector and a method thereof. The optical information collector includes an image sensor, configured to collect image data of optical information; a decoding unit, configured to decode the image data based on a preset decoding algorithm; a central processor, configured to control the image sensor to collect the image data and control the decoding unit to decode the image data upon triggering. Once triggered, the central processor issues an instruction to discard N frames of image data in a specific frame number, where the N frames of image data in a specific frame number is image data that was previously collected and remaining in the optical information collector upon triggering, which can prevent residual image data from being decoded and outputted, causing a decoding error, thereby improving a decoding efficiency.

Abstract: This application provides a storage system includes disks grouped into disk groups. One disk group processes an IO service, and another disk group is in an energy-saving state or a sleep state and provides a standby disk for a previous disk group. IO load is focused on a disk in one disk group, so that a requirement for processing the IO service is satisfied by using this group of disks. In addition, the another disk group may save energy or sleep, so that more energy consumption can be reduced. Moreover, resource pools of different levels are implemented by using a plurality of disk groups. When a disk in a previous disk group is in shortage, a capacity of the previous disk group can be expanded by using a next disk group.

Abstract: A power consumption management method and a power consumption management device are provided. When a power module of a power supply for a server is faulty, a power consumption management device receives fault information sent by the power supply, and reduces first power consumption, calculated when the power module works normally, of the server by a first value to second power consumption of the server based on the fault information. The first value is not less than a reduced value, calculated when the power module is faulty, of power consumption of the server. In addition, the power consumption management device adjusts the second power consumption of the server based on a power consumption capping value of the server. According to the application, a breakdown of the server is avoided, and the power utilization after the power module is faulty is further improved.
