Provided are a signal adjustment method for a PPG apparatus and a PPG apparatus. The method comprises: when background light data or actual effective light data does not meet a preset background light data range or a preset first effective light data range, performing a dimming operation comprising: determining an estimated current transfer ratio; estimating a driving current required by a light source and a gain required by an analog front end; calculating estimated effective light data of a PPG apparatus according to the estimated driving current required by the light source, the gain required by the analog front end, and the estimated current transfer ratio; when the estimated effective light data meets a preset second effective light data range, generating a to-be-adjusted current/gain value according to the estimated driving current required by the light source and the gain required by the analog front end.

Signal adjustment method for PPG apparatus and PPG apparatus

A method, apparatus and system for controlling a smart device based on a headphone are disclosed. The method includes: collecting, by the headphone, head motion feature data of a human body if a trigger condition of a collection task is satisfied; judging, according to the collected data, whether a target motion feature satisfying a predetermined motion feature is present in head motion feature of the human body; and if the target motion feature is present, acquiring information of an application currently running on the smart device, and generating an operation control instruction corresponding to the target motion feature according to the information of the currently running application and sending the operation control instruction to the smart device. According to the present application, control function may be enhanced for the smart device and control accuracy may be improved.

Method, apparatus and system for controlling smart device based on headphone

A method for switching working modes of a headphone, and a headphone are disclosed. The method includes: receiving, via a sound channel of the headphone, a signal sent by a smart terminal; processing the signal; and when a command indicative of switching the working modes of the headphone is obtained after the signal is processed, controlling, a switch module of a microphone channel to switch the working modes according to the command such that the headphone is switchable between a call mode and an application data transmission mode. The working modes of the headphone may be automatically switched, and thus user experience may be improved.
