Abstract: A method for detecting an MPI noise problem. The method includes: receiving a first signal, where the first signal includes a service signal sent by a sending device and an MPI noise signal generated by an MPI noise generator, and the MPI noise generator is disposed between the sending device and a receiving device of the service signal; determining whether a packet loss occurs in the service signal; and when a packet loss occurs in the service signal, determining that there is an MPI noise problem in an optical fiber link between the sending device and the receiving device. Therefore, when a packet loss occurs in a service signal that passes through an optical fiber link between a transmit end and a receive end, it can be determined that there is an MPI noise problem in the optical fiber link.

Abstract: Embodiments provide a user interface display method for a terminal, and a terminal. The method includes: generating, by a terminal in a first operating environment, a first user interface that includes a first input component, obtaining a first user interface picture according to the first user interface, and determining attribute information of the first input component according to a first application. The method also includes switching, by the terminal, to a second operating environment, and displaying a second user interface in the second operating environment according to the first user interface picture and the attribute information of the first input component, thereby reducing processing overheads of the terminal.

Abstract: This application discloses a method for controlling an electronic device to perform photoplethysmography detection. The method includes obtaining historical detection data of a photoplethysmography sensor, calculating a confidence of the historical detection data, determining, based on the calculated confidence of the historical detection data, whether a light source to be turned on by the photoplethysmography sensor in a next detection time segment includes a light source different from a light source turned on when the historical detection data is obtained, and determining that a photoelectric sensing element to be turned on in the next detection time segment is a photoelectric sensing element corresponding to the determined light source to be turned on.

Abstract: In a method, a terminal device obtains at least one template source file of a first contact in different ways, and when the terminal devices obtains a face picture in a currently displayed picture through facial recognition, and determines that a first face template included in a first face information template successfully matches the face picture, the terminal device sends, based on contact information, a multimedia file to a first contact to which the first face template belongs. The multimedia file is the picture, a picture set or a video file including the picture, or a picture or a video file generated based on the picture.

Abstract: Various embodiments relate to the field of communications technologies, and provide a light adjustment method and a terminal to resolve a problem that an existing light therapy device cannot flexibly adjust light based on a light requirement of a user and cannot more intelligently adjust a circadian rhythm of the user. In those embodiments, an awake time period and a sleep time period of a user is determined by the terminal, and parameter thresholds in the awake time period and the sleep time period is determined by the terminal. In those embodiments, a light parameter in a current time period is obtain by the terminal, and based on the light parameter in the current time period, a light parameter of light emitted by a light source device is then adjusted by the terminal.

Abstract: A photoplethysmogram (PPG) authentication method and device, where it is detected whether a terminal currently meets a PPG signal pre-collection trigger condition, and collection of a current PPG signal of a user is triggered only when the PPG signal pre-collection trigger condition is met such that the PPG signal of the user is pre-obtained before an application requests PPG authentication. In this way, when it is detected that the application initiates a PPG authentication request, PPG authentication may be directly performed based on a most recently collected PPG signal, thereby ensuring timeliness of PPG authentication, avoiding resource consumption caused by periodic PPG signal collection, and reducing power consumption.
