  • Patent number: 10771683
    Abstract: Accurate motion detection is performed by discriminating whether a sensor detecting an object motion is mounted on a human body or not, and processing is executed with respect to metadata based on the result. Sensor information according to the motion is input from the sensor, and a sensor mounting position is determined. A sensor mounting position detection unit calculates a ratio between a high-frequency component and a low-frequency component included in the sensor information, and discriminates whether the sensor is mounted on the human body or is mounted on other than the human body, on the basis of the calculated ratio. A metadata generating unit inputs user motion detection information obtained by executing a motion detection algorithm assuming a sensor mounting position coincident with a sensor mounting position detection result, and generates the shot image corresponding metadata.

  • 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.

    Abstract: A pulse oximetry measurement system uses a pseudo-random noise generator to stimulate one or more light emitting diodes (LEDs). The light amplitudes from these LEDs, after passing through a part of a body, are detected by a phototransistor or photodiode and digitized with an analog-to-digital converter (ADC). The digitized ADC light amplitude values are re-correlated with the outgoing pseudo-random noise stimulus. Spread spectrum techniques are known for their noise mitigation properties, and ability to pass multiple signals through the same medium without interference.

    Abstract: A computer-implemented method for characterizing circulatory blood volume is disclosed. The method has the steps of acquiring a biological signal that emulates the arterial pulse wave from a sensor. Two derived parameters, circulatory stress, which reflects a harmonic of heart rate, and circulatory blood flow, which reflects the amplitude of the unprocessed biological signal, are extrapolated from the biological signal, and are each compared to a threshold value and assessed to determine an adequacy of circulatory blood volume. In embodiments, the assessment of circulatory blood volume is used to manage a patient's cardiovascular autoregulatory function or the adequacy of transfer of fluids to and from the circulatory system, with the ultimate goal of achieving a circulatory blood volume that adequately supplies the demands of the patient's tissues and organs.

Changes in T3 minus T1 are indicative of something happening to blood volume. If the T1-3 value goes up and the patient is on an infusion system, it can be an indication of having too much fluid pumped and if T1-3 is lower than it should be for an individual, they are either dehydrated (which can result in decreases in blood volume), they are hemorrhaging, or they have hemorrhaged.

    Abstract: A method of optical heart rate sensing includes receiving a motion frequency from a motion sensor and receiving an optical signal from an optical sensor. The motion frequency is then filtered from the optical signal, and an estimated heart rate frequency is determined based on the filtered optical signal. A heart rate is reported that is based on the motion frequency, but not based on the estimated heart rate frequency, when a local neighbor magnitude ratio of the estimated heart rate frequency is below a confidence threshold.
