  • Patent number: 10750959
    Abstract: A system and method for real time estimation of heart rate (HR) from one or more face videos acquired in non-invasive manner. The system receives face videos and obtains several blocks as ROI consisting of facial skin areas. Subsequently, the temporal fragments are extracted from the blocks and filtered to minimize the noise. In the next stage, several temporal fragments are extracted from the video. The several temporal fragments, corrupted by noise are determined using an image processing range filter and pruned for further processing. The HR of each temporal fragment, referred as local HR is estimated along with its quality. Eventually, a quality based fusion is applied to estimate a global HR corresponding to the received face videos. In addition, the disclosure herein is also applicable for frontal, profile and multiple faces and performs in real-time.

  • Patent number: 10716487
    Abstract: A method for obtaining an electroencephalogram (EEG) of a user is disclosed. A reference sensor is attached to the user by connecting a first component of the reference sensor to a second component of the reference sensor, at least a portion of the first component being sub-dermally implanted on or adjacent to a mastoid process of the user. At least one active sensor is attached to the user. A first signal is detected from the reference sensor simultaneously as a second signal is detected from the at least one active sensor. The EEG is obtained based on the first signal and the second signal.

  • Patent number: 10667714
    Abstract: Provided are a method and system for detecting information of brain-heart connectivity, the method comprising: obtaining moving images of a pupil and an electrocardiogram (ECG) signal from a subject; acquiring a pupil size variation (PSV) from the moving images by separating the moving images at a predetermined time range after R-peak of the ECG signal; extracting signals of a first period and a second period from the PSV; calculating alpha powers of the signals of the first and second periods at predetermined frequencies respectively.

  • Patent number: 10617329
    Abstract: According to an embodiment of the present invention, a physical monitoring device is in the form of a necklace or pendant and includes an object (e.g., stone, gem, glass, crystal, or other transparent or translucent object that conveys light signals or color). The physical activity monitoring device includes one or more sensors to measure physical activity or motion of the user (e.g., steps, distance traveled by foot, body motion, etc.). The object is illuminated or changed to different colors to openly and outwardly indicate a level of physical activity of the user.
