    Abstract: A method and system for blood pressure (BP) estimation of a person is provided. The system is estimating pulse transit time (PTT) using the ECG signal and PPG signal of the person. A plurality of features are extracted from the PPG. The plurality of PPG features and the PTT are provided as inputs to an automated feature selection algorithm. This algorithm selects a set of features suitable for BP estimation. The selected features are fed to a classifier to classify the database into low/normal BP range and a high BP range. The correctly classified normal BP data are then used to create a regression model to predict BP from the selected features. The current methodology uses automated feature selection mechanism and also employs a block to reject extreme BP data. Thus the available accuracy in predicting BP is expected to be more than the existing BP estimation methods.

  • Patent number: 10955323
    Abstract: To provide a method whereby viscoelasticity of an object can be measured nondestructively and in non-contact fashion in a short time. By this method, elastic waves and light are radiated to an object and the viscoelasticity of an object is measured nondestructively and in non-contact fashion using a shadow change based on a change in the direction of a line normal to the surface of the object. Specifically, the present invention has an elastic wave transmission step for pressurizing or exciting the object by elastic waves and causing a minute displacement of the object surface shape, a photoirradiation step for radiating light to the minutely displaced object surface, an image acquisition step for acquiring a shadow change based on a change in the direction of a line normal to the object surface, and a viscoelasticity estimation step for processing an image of the acquired shadow change and calculating a viscoelasticity.

  • Patent number: 10925516
    Abstract: A method and apparatus is proposed to estimate the aortic pulse transit time (PTT) from only time intervals measured between fiducial points of the longitudinal ballistocardiogram (BCG) without the need to apply any sensor to the area where the arrival of the arterial pulse waveform is to be detected. From the longitudinal BCG of a subject, which can be obtained by means of sensors integrated in a single element with which the subject's body comes into contact, two fiducial points of the BCG waveform are detected in which one of the points is associated with the arrival of the arterial pulse wave to a zone proximal to the heart and the other is associated with the arrival of said arterial pulse wave to a distal zone, respectively. From the time interval between the two points, an estimate of the aortic (carotid-femoral) PTT is provided either directly or through a process of previous calibration.
