Abstract: This application provides a display method and an apparatus. The display method includes: determining that a refresh rate of an electronic device is switched from a first refresh rate to a second refresh rate, where the first refresh rate is greater than the second refresh rate; generating, in a case that the refresh rate is switched from the first refresh rate to the second refresh rate, a second image frame after the electronic device completes display of a first image frame; and displaying the second image frame. An objective is to resolve a frame loss problem caused by switching from a high refresh rate to a low refresh rate, to reduce lag in the electronic device, and improve user experience.

Abstract: A method and device are provided for diagnosing a weighing system. In the method, the weighing system acquires an intrinsic parameter, a status parameter, and an operating parameter of various components of the weighing system, environmental parameters of the weighing system application, and communication data and interaction data among all the components. A first-level prompt is sent when the status of any of the components is abnormal, such that the system stops operating. A second-level prompt is sent when the status of each of the components is normal and the service life status of at least one of the components reaches a preset threshold. A third-level prompt is sent when the status of each of the components is normal and a system performance abnormality event is identified for the performance status of the system. A fourth-level prompt is sent when the status of each of the components is normal.

Abstract: A method for controlling dynamic change of a screen refresh rate and an electronic device are provided. In a scenario of dynamic change of the refresh rate, a refresh rate switching instruction may be sent immediately through an added refresh rate setting interface (displaySetFps) within a current ith frame period before a current Vsync periodicity ends. After receiving the refresh rate switching instruction, a DDIC drives a display screen to switch a screen refresh rate, and then the DDIC returns a new TE signal. After receiving the new TE signal, SurfaceFlinger starts a new Vsync periodicity corresponding to a switched screen refresh rate. In an embodiment of this application, a switching speed at which the screen refresh rate is switched may be increased by adding a new path. For example, it may be ensured that each switching of the screen refresh rate is completed within one frame.

This application can solve the problem of speed fluctuation caused by frame rate switching in displaying an image frame on electronic devices.

Abstract: A dynamic weighing device has a plurality of weighing sensors that constitute a weighing sensor network via Ethernet. One of the weighing sensors is selected as a primary node, which performs time synchronization with the other nodes via a time synchronization protocol. Alternatively, the other nodes synchronize a time offset relative to the time of the primary node. Each weighing sensor continuously packetizes and sends a plurality of consecutive pieces of weighing information to a terminal apparatus. The terminal apparatus calculates a weighed weight result of the dynamic weighing device at the same moment, based on time information in the weighing information obtained through depacketization, In such a weighing sensor network, by means of the time synchronization, weighing data at each moment is accurate when the weighing data is processed on a terminal such as a meter, thereby improving the reliability of sampling.
