Abstract: A laser radar integrated box at least includes an outer housing (A10), a lifting device (A20), a laser radar (A40), a controller (A50), and a lower cover plate (A60); the lifting device (A20), the laser radar (A40), and the controller (A50) are located between the outer housing (A10) and the lower cover plate (A60); the laser radar (A40) is located above the lifting device (A20); and the lifting device (A20) can extend or retract under the control of the controller (A50) to drive the laser radar (A40) to extend to the outside of an automobile or retract to the inside of the automobile. The laser radar integrated box can be flexibly arranged on the roof of a vehicle. Further disclosed are a cleaning device and a vehicle.

Abstract: A face recognition method includes generating a target face recognition model, performing face detection on an image to obtain a first face image, and performing face recognition on the first face image in the image by using the target face recognition model to obtain a first face feature. Generating the target face recognition model includes determining a training sample, the training sample comprising a training face image calibrated with identity information, and training a general face recognition model by using the training sample, and updating a parameter of the general face recognition model based on a training target to obtain the target face recognition model, the training target being a prediction result of the general face recognition model predicting identity information of a new training face image in the training sample to be the calibrated identity information of the training face image in the training sample.

Abstract: The present disclosure relates to the technical field of dissimilar welding of Cu and a steel, and in particular to a welding wire for dissimilar welding of Cu and a steel and a preparation method thereof and a method for welding Cu and a steel. The present disclosure provides a welding wire for dissimilar welding of Cu and a steel, including, in percentages by mass, 5-25% of iron phase, less than 0.1% of inevitable impurities, and copper matrix. The welding wire of the present disclosure, containing two elements, i.e. copper and iron, is conducive to the mixing of the two phases—copper and iron—during the welding process, to form a mutual soluble region, thereby makes it possible to greatly increase the weldability, reduce the width of the weld, effectively overcome the tendency of cracks, and thus to ensure the formed weld with a high crack resistance.

Abstract: Disclosed are a sidebar interaction method, a device and a computer readable storage medium. The method includes: receiving an instruction to initiate an interaction, generating an interaction module on a currently operating interface of a front-end application, outputting at least one notification message in the interaction module; initiating a back-end application, displaying a sidebar in a first target display area on the currently operating interface; and detecting a preset operation corresponding to the sidebar and responding to the preset operation. The sidebar interaction module is arranged, and notification message interception is carried out through the sidebar interaction module, so that the interference is reduced when different applications or different functions of the same application interact. The sidebar interaction is more reasonable.

Abstract: Disclosed are interacting methods for sidebar menu, apparatus, and storage medium thereof. The interacting methods display a shortcut panel for displaying first shortcut button icons upon receiving a triggering instruction, and displays another shortcut panel, an editing panel or an editing interface upon receiving another triggering instruction, for editing the first shortcut button icons. Before the triggering instruction is received, the first shortcut panel runs in the background, and there is no resident bar displayed on the mobile terminal, thus, users will not be affected by the shortcut panels. The purpose of eliminating the resident bar of the shortcut panel and voiding the shortcut panel affecting the users' normal use of the mobile terminal is achieved.

Abstract: Described is a method and system for displaying an unread message. The method for displaying an unread message includes: pulling an unread message in a lock screen state; and displaying a corresponding unread message application icon on a first active hotspot on a lock screen when an unread message exists, and otherwise, hiding the unread message application icon. The method for previewing an unread message includes: receiving information for activating an unread message application icon in a lock screen state, and displaying a detail entry containing a predetermined number of unread messages on a second active hotspot; dragging the unread message application icon to a third active hotspot to enter into a corresponding application main window, or dragging the unread message application icon to the detail entry to enter into a message window corresponding to the detail entry.

Abstract: The present disclosure, pertaining to the field of network applications, discloses an application login method and apparatus, and a mobile terminal therefor. The method includes: verifying an application upon receiving from a user a request for logging in to the application; returning at least one locally stored account if the application is successfully verified; and logging in to the application using an account upon detecting that the user selects the account from the at least one locally stored account. The apparatus includes: a receiving module, a verifying module, a returning module, and a login module. According to the present disclosure, upon receiving from a user a request for logging in to an application, a terminal verifies the application; when the application is successfully verified, the terminal provides a stored account for the application, such that a plurality of applications provided by the same operator share the same account and password.
