This invention discloses an adaptive method, apparatus, and system for high-quality pulse wave extraction in automatic pulse diagnosis, belonging to the field of traditional Chinese medicine pulse diagnosis information processing technology. The method first acquires and preprocesses multi-pressure pulse wave sequences; then, for each single-cycle pulse wave, a quantitative evaluation vector is constructed from four dimensions: temporal stability, morphological consistency, signal purity, and physiological feature prominence; next, weights for each dimension are dynamically assigned based on the extracted individual physiological characteristics, and a weighted fusion is performed to obtain a comprehensive quality score; finally, a screening threshold is dynamically determined based on the distribution of the comprehensive quality score, and the optimal pulse-taking pressure range is determined by combining pressure value clustering analysis, from which a set of high-quality pulse waves is selected. This invention achieves objectivity and quantification of the evaluation process, adaptively extracts pulse waves with both high signal quality and high diagnostic value, and provides feedback for optimizing pulse-taking pressure, making it suitable for widespread use in traditional Chinese medicine pulse diagnosis.

The application discloses a control method and device of a flexible actuator, a computing device and cluster and a robot, and belongs to the technical field of flexible actuator control. The method comprises the following steps: converting a target motion instruction into a pulse sequence; inputting the pulse sequence into a pulse neural network to cooperatively generate a multi-channel pulse control signal; converting the multi-channel pulse control signal into a driving signal and applying the driving signal to a plurality of flexible driving units to make the flexible driving units produce cooperative deformation; collecting deformation state information and converting the deformation state information into a feedback pulse sequence, and inputting the feedback pulse sequence into the pulse neural network to close-loop adjust the multi-channel pulse control signal. The application takes pulses as a unified information format to run through the control of the whole link, realizes multi-unit dynamic cooperation and closed-loop accurate control, effectively improves the flexibility, stability and integration of the flexible actuating system, and can be widely applied to the fields of soft robots, medical rehabilitation and wearable devices.
