    Abstract: Disclosed is a heart rhythm monitoring apparatus, including a water-proof case, a water-proof patch, at least two electrodes, a battery, and an electric circuit. The water-proof case is attached to the water-proof patch to form a water-proof space for accommodating the battery and the electric circuit. Each electrode is connected to the electric circuit, and outwards extends from the water-proof space to form a sensing end. The electrodes penetrate the water-proof patch and the water-proof patch and the sensing ends contact an animal skin. The water-proof patch provides adhesion, and the sensing ends are configured to sense electrical signal on the animal skin. The electrical signal is processed by the electric circuit, and the corresponding heart rhythm information is acquired and recorded. The present invention provides water-proof feature and possesses a simple structure, thereby improving convenience of use, prolonging operation period, acquiring a long-term record of heart rhythm information.

  • Publication number: 20200054232
    Abstract: The present disclosure facilitates the evaluation of wide-band phase gradient information of the heart tissue to assess, e.g., the presence of heart ischemic heart disease. Notably, the present disclosure provides an improved and efficient method to identify and risk stratify coronary stenosis of the heart using a high resolution and wide-band cardiac gradient obtained from the patient. The patient data are derived from the cardiac gradient waveforms across one or more leads, in some embodiments, resulting in high-dimensional data and long cardiac gradient records that exhibit complex nonlinear variability. Space-time analysis, via numeric wavelet operators, is used to study the morphology of the cardiac gradient data as a phase space dataset by extracting dynamical and geometrical properties from the phase space dataset.

  • Publication number: 20200054236
    Abstract: A security check method includes: pre-creating at least four concurrently operating threads, one thread being responsible for movement control and data acquisition, one thread being responsible for imaging processing, one thread being responsible for interface displaying, and one thread being responsible for target detection and recognition; then the four concurrently operating threads divide original echo data of a human body to be checked into data of a plurality of adjacent overlapped azimuthal segments during data processing and perform individual processing on the data of each azimuthal segment. The security check system includes a thread creating unit, a first thread parallel unit, a second thread parallel unit, a third thread parallel unit, a fourth thread parallel unit, and a thread loop control unit. Because subsequent data processing is not required to be performed after the acquisition of all data is completed, the time for a security check process is reduced.
