Abstract: 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.

Abstract: A method for sampling biometric data, a sampling and managing apparatus thereof, an apparatus for detecting biometric data, and an electronic device are provided. The method for sampling biometric data includes: determining, based on a preset sampling rule, a sampling configuration corresponding to a sampling time slot in a sampling refresh period, the sampling refresh period including a plurality of the sampling time slots; and controlling, based on the sampling configuration corresponding to the sampling time slot in the sampling refresh period, a sampling channel corresponding to the sampling time slot to sample a target signal to obtain sample data associated with the biometric data, thereby improving the flexibility in sampling process control.

Abstract: 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.

Abstract: 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.

Abstract: A client platform and a cloud storage terminal for cloud storage includes a client interface adapted to connect to a client terminal which is communicated with multiple cloud storage servers, multiple partitions corresponding to multiple cloud storage applications, in which there is a mapping relationship between the multiple partitions and the multiple cloud storage servers, a user interface configured to receive a user input and a control module configured to perform a first operation on at least one of the multiple partitions based on the user input.

Abstract: Provided are early-warning methods and early-warning devices for indicating a usage condition of a semiconductor storage device comprising a semiconductor storage medium. The semiconductor storage medium comprises a plurality of physical storage blocks. The method comprises: retrieving a usage condition value; comparing the usage condition value with a preset threshold; and providing an early-warning signal based on a result of the comparison, wherein the usage condition value comprises one of an average number of used times of the blocks and a maximum number of used times of the blocks. Since the early-warning is used to indicate the usage condition information of the semiconductor storage medium, users may be aware of when the lifetime of the semiconductor storage medium will expire so that important data can be backed up before the storage device is aged, thus ensuring safety of the data and avoiding data lost.
