Title:
PRESSURE RECOGNITION BRACELET
Document Type and Number:
WIPO Patent Application WO/2021/147901
Kind Code:
A1
Abstract:
Disclosed is a pressure recognition bracelet, comprising a main housing (110), a watch strap (120) connected to the main housing (110), a physiological index collection assembly (130), a processor module (140), and a power supply assembly (150), wherein the processor module (140) is used for sequentially collecting, at a specified time interval and within a set period, time domain signals of discrete periods formed by various vital sign signals. Feature sequences to be tested of the vital sign signals of a subject are extracted by means of a short-time Fourier transform and a continuous wavelet transform, such that the characteristics of a variety of vital signs are retained. A set number of sample feature sequences that are stored in a standard pressure database and are closest to said feature sequences are acquired by means of similarity matching, and a pressure level at which most of the sample feature sequences are is determined to be a pressure level at which the subject is. The effective evaluation of a pressure state of the subject is thus realized with a high credibility and a high detection speed.
