Abstract: This application relates to the field of battery technology, and in particular, to a box assembly, a battery module, a battery, and an electrical device. The box assembly may include at least a partition piece and two end plates. In the box assembly disclosed herein, a stress relief piece may be disposed at two ends of a main body of the partition piece. The main body may be connected to the end plate by use of the stress relief piece. A corner may be formed between the stress relief piece and the main body. In this way, when the battery module is subjected to stress, at least a part of the stress can be relieved through the corner formed between the stress relief piece and the main body.

Abstract: A method includes acquiring multiple pieces of first received signal quality information at a receiver, where the multiple pieces of first received signal quality information represent qualities of signals received at the receiver, generating first conditional sample statistical values based on the multiple pieces of first received signal quality information and phase shift arrays corresponding to the signals, determining the first phase shift array that meets a communication requirement according to the first conditional sample statistical values, where the first phase shift array includes the phase shift value for at least one reflective element of an IRS, and configuring the IRS based on the first phase shift array.

Abstract: The present disclosure provides a signal processing method, comprising: obtaining a Doppler ultrasound signal; converting two adjacent groups of ultrasound signals of the Doppler ultrasound signal into frequency domain signals, and obtaining a result of the signal filling by filling missing ultrasound signals in a preset time period based on the frequency domain signals, the preset time period being an acquisition time interval of the two adjacent groups of ultrasound signals; and determining a target Doppler ultrasound signal based on the result of the signal filling.

Abstract: The embodiments of the present disclosure provide a method and a device for signal processing. The method includes: obtaining multiple sets of initial Doppler blood flow signals, sampling times of the multiple sets of initial Doppler blood flow signals being discontinuous; and performing a splicing processing on the multiple sets of initial Doppler blood flow signals, to obtain a target Doppler blood flow signal.

Abstract: The present disclosure provides a method for ultrasound image processing. an ultrasound image may be obtained. The ultrasound image may be associated with the blood flow velocity. An envelope curve may be determined based on ultrasound image. A plurality of first maximum points of the envelope curve may be determined. A plurality of second maximum points may be obtained by screening the plurality of first maximum points based on amplitude features of the plurality of first maximum points. A plurality of third maximum points may be obtained by correcting the plurality of second maximum points according to time features of the plurality of second maximum points. One or more parameters relating to the blood flow velocity may be determined based on the plurality of third maximum points.

Abstract: An electronic device displays a first selection screen and displays adjustment controls corresponding to information display positions of at least one second user. The electronic device receives a trigger operation on a first adjustment control. In accordance with the receiving, and responsive to a determination that the first adjustment control is in a first display status, the electronic device displays the first adjustment control in a second display status. In response to a determination that the trigger operation on the first adjustment control is accepted by a first target user, the electronic device displays a second selection screen that includes an exchange in the information display position of the first user and the information display position of the first target user. The disclosed implementations improve user interaction efficiency during virtual character selection in gaming applications.

Abstract: This application discloses an information display method performed by a terminal. The method includes: displaying a user interface of a target application; displaying mandatory reading information and first prompt information corresponding to the mandatory reading information in the user interface in response to a display trigger operation; and displaying second prompt information corresponding to the mandatory reading information in the user interface in response to an end of a mandatory reading time. In this application, a user is prevented within a mandatory reading time from triggering a trigger operation to which a client needs to respond, processing overheads of detecting trigger operations by the client are reduced, and the user is prevented from getting upset about not being able to determine whether the mandatory reading time has ended, thereby improving user experience.

Abstract: A method for implementing Automatic Protection Switching (APS) between an active board and a standby board includes detecting Synchronous Digital Hierarchy (SDH) data of main services, wherein the SDH data is received by a working port of the active board from a working line. If the SDH data received by the working port is detected as abnormal, SDH data of main services received by a protection port of the standby board is selected from a protection line, and service processing is performed for the SDH data.

Abstract: The present disclosure relates to the communications field and discloses a method, an apparatus, and a system for transmitting packet service data Packet service data is sent by a User Equipment (UE). It is determined whether the packet service data is Internet service data according to a pre-obtained Internet service offloading policy. If the packet service data is Internet service data, the packet service data is transmitted to a Public Data Network (PDN) via a Metropolitan Area Network (MAN) and an IP backbone. Embodiments of the present disclosure may be applied to wireless communication systems such as a WCDMA system.
