Abstract: The present disclosure disclosed an information presentation method and apparatus, a device and a storage medium. The method comprises: during a process of a preset application presenting a multimedia stream, detecting that a preset reminding event is triggered; presenting first multimedia content which includes preset prompt content; and forbidding switching to second multimedia content, displaying first copywriting information, and playing matched first voice information.

Abstract: This application provides a fireproof component, a battery pack, and a device using the battery pack as a power supply. The fireproof component includes a main body and a frame. The frame includes a body portion, an extension portion, and an opening defined by an inner peripheral face of the body portion. The extension portion is located circumferentially outside the body portion and connected to the body portion. The extension portion extends along a third direction that is perpendicular to a plane defined by the frame and protrudes beyond the body portion. The main body covers the opening of the frame and is connected to the body portion. The main body and the frame of the fireproof component are parts independent of each other, and therefore, can be made of different materials and in different molding processes.

Abstract: A display compensating method, display compensating device, and display device are provided, which relates to field of display and addresses the issues of poor screen uniformity, grayscale relationship change of sub-pixel due to ambient temperature change, and display screen brightness affected by ageing offset of threshold voltage corresponding to the sub-pixel. The display compensating method is applied to the display device, including: converting a received grayscale signal into a brightness signal; performing an optical compensation on a display brightness of the display device based on the brightness signal; converting a corresponding brightness signal on which the optical compensation is performed into a voltage signal; compensating for a threshold voltage corresponding to each sub-pixel in the display device based on the voltage signal; and compensating for operating parameters of the display device for the display device at different operating temperatures.

Abstract: Disclosed in the embodiments of the present disclosure are a display control method and apparatus, and a device and a storage medium. The method includes: plays a first video in a first display area in a video stream playing interface of a preset application program. The method further receives a switching instruction. When a preset reminding condition is met, the method switches to play a second video in the first display area. The display area for the second video is changed from the first display area to a second display area during the playing process, and the size of the second display area is smaller than the size of the first display area. In addition, the method displays preset prompt information outside the second display area in the video stream playing interface.

Abstract: The present disclosure provides a multi-view collaborative tracking method and apparatus for a fast moving target under a low luminance condition, including a multi-view target tracking algorithm based on radar-vision fusion data and an unmanned aerial vehicle (UAV) cluster collaborative tracking technology. This method takes the spatiotemporal normalized multi-source data as the learning objective of multi-agent reinforcement learning, to drive the cluster to collect data from multiple angles and directions. In this way, highly-efficient multi-angle collaborative observation can be performed on a high-speed moving object in an environment of weak texture and low luminance.

Abstract: A dimming method for a display panel is provided, including: acquiring image data of an image to be displayed; determining initial dimming pixel data of each of dimming pixels according to the image data; determining a dimming pixel to be filtered in the dimming screen according to the initial dimming pixel data of each of dimming pixels; determining a first filtering region according to the determined dimming pixel to be filtered; determining a filtering parameter of each of dimming pixels in the first filtering region according to a relationship between each of dimming pixels in the first filtering region and initial dimming pixel data of each of dimming pixels in the first filtering region; and updating dimming pixel data of the dimming pixel to be filtered according to the filtering parameter of each of dimming pixels in the first filtering region, so as to obtain updated dimming pixel data.

Abstract: A correlated sparse nodes and mini-streamers system for collecting seismic data includes plural nodes distributed on the ocean bottom, and a mini-streamer spread that includes plural mini-streamers. The plural nodes and the mini-streamer spread are configured to simultaneously collect seismic data from a surveyed subsurface, and wherein a length of the mini-streamers is equal to or less than three times an inline distance between adjacent nodes of the plural nodes.
