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: A method includes obtaining a filtered waveform signal, marking the waveform signal as K signal line segments based on monotonicity, extracting line segment data of each signal line segment, and determining a line segment matching template of the waveform signal based on the line segment data of each signal line segment, where the line segment matching template includes M consecutive signal line segments, and M is an integer less than K. The method further includes matching each of the K signal line segments with the M signal line segments included in the line segment matching template, and determining a target wave group of the waveform signal based on a matching result of each signal line segment. The method further includes determining periodic signal data of the waveform signal based on line segment data of the target wave group.

Abstract: A diagnosis report generation method and terminal device are provided. The method includes obtaining electrocardiography ECG data, determining that the ECG data includes abnormal heartbeat data, obtaining, based on the ECG data, an abnormal heartbeat waveform corresponding to the abnormal heartbeat data, combining a normal heartbeat waveform and the abnormal heartbeat waveform to obtain an abnormality comparison image, and generating a diagnosis report based on the abnormality comparison image. The abnormal heartbeat waveform is obtained by extracting and analyzing the ECG data, so that the abnormal heartbeat waveform can be combined and compared with the normal heartbeat waveform, to obtain the abnormality comparison image for generating the diagnosis report.

Abstract: Embodiments of the present disclosure disclose a copyright authorization management method and system. The method includes: obtaining owner-of-copyright information; sending a contract determining notification to a corresponding owner-of-copyright client based on the owner-of-copyright information, where the contract determining notification carries copyright-related information of a to-be-authorized work; receiving transaction information returned by the owner-of-copyright client, where the transaction information includes contract information determined by an owner of copyright based on the copyright-related information; obtaining a valid contract transaction based on the transaction information, where the valid contract transaction includes signatures satisfying a preset-quantity rule; and implementing persistence of the valid contract transaction in a block chain. In technical solutions provided in the embodiments of the present disclosure, online contract signing and persistence of a signed contract are implemented based on the block chain. This improves copyright authorization efficiency, and ensures that the contract is unique, trustworthy, and unalterable.
