Abstract: An electronic device includes a movable assembly. An optical proximity sensor is disposed on the movable assembly. The movable assembly may be spaced from a fixed assembly on the electronic device, and the movable assembly can move on a plane that is disposed in parallel relative to the fixed assembly. A light intensity of light that is from the optical proximity sensor and that is reflected by the fixed assembly may reflect a position of the movable assembly relative to the fixed assembly. Whether the movable assembly moves to a specified target position may be determined based on the light intensity of the light that is reflected by the fixed assembly and that is detected by the optical proximity sensor.

Abstract: An electronic device includes a first graphics processing subsystem, a second graphics processing subsystem, and a screen. The first graphics processing subsystem includes a first application processor, a first graphics processing unit, and a first memory. The second graphics processing subsystem includes a second application processor, a second graphics processing unit, and a second memory. The first graphics processing unit renders a first GUI. The screen displays the first GUI. The second graphics processing unit renders a second GUI, and the second GUI and the first GUI belong to different interface types. The screen displays the second GUI. A display processing method applied to the electronic device is also provided, wherein the first graphics processing subsystem can be switched to the second graphics processing subsystem based on complexity of a to-be-displayed GUI.

Abstract: A wearable device collects a fingerprint pattern input by a user and speech input by the user. The wearable device sends the fingerprint pattern to an electronic device, to enable the electronic device to perform authentication on the fingerprint pattern input by a user. The wearable device sends the speech to the electronic device, and, upon a determination that the authentication succeeds, the electronic device is enabled to execute a function corresponding to the speech.

Abstract: A traffic control method, a traffic controlling device, and a terminal are provided, which relate to the field of communications technology. The traffic control method includes the following. A working temperature of equipment is monitored. It is determined whether the working temperature reaches a control temperature. If the working temperature reaches the control temperature, a rate of data interaction between the adjacent function layers is controlled. The adjacent function layers are two random adjacent function layers in a Transmission Control Protocol/Internet Protocol (TCP/IP) 7-layer model. Therefore, a user can use equipment normally when power consumption of wireless terminal equipment is reduced.
