Abstract: The present technology relates to systems and methods for evaluating a user's sleep data. More particularly, the present technology contemplates a computer-implemented system or method of evaluating a quality of sleep for a user based on sleep data, such as by determining a set of quality metrics for the user's sleep based on the sleep data using a set of probabilistic models.

Abstract: The present invention relates to a wearable device for healthcare and method for using the device. More specifically, the wearable device is worn on a finger for measuring the health data of the user, selected from one or more of heart rate, blood oxygen saturation, heart rate variability. Based on the measured data, the sleep quality can be monitored and recorded. Disorders such as obstructive sleep apnea (OSA), can be detected. The wearable device may include an optical sensor coupled with or embedded in a main body including a visible light emitter, an IR light emitter and a light detector being arranged along a longitudinal direction of the finger. During operation of the wearable device, the heart rate is monitored based on a detected light signal. When the heart rate is higher than an adaptive threshold, both heart rate and blood oxygen saturation are monitored.

Abstract: An electronic device measures physiological information of a living subject. The electronic device includes a sensor assembly, a first driving unit with an electromagnetic structure and a second driving unit. The first driving unit drives the sensor assembly to scan the living subject's skin along a scan path in a non-contact way to determine a measuring position. The second driving unit drives the sensor assembly to move towards and contact the living subject's skin to measure the physiological information based on the measuring position. In a typical embodiment, the sensor is configured under a measurement surface where a wrist of a user is put on. The sensor scans the user's wrist along a scan path under the wrist in a non-contact way and move upwards to contact the user's wrist for measuring the physiological information based on the scanning result.

Abstract: Techniques for effectively and accurately measuring psychological influencing factors, such as the white coat effect and mental stress, that may affect or otherwise influence biometric measurements, such as blood pressure measurements, are described. Embodiments of a measurement validation system herein may utilize a method for determining an artery location on a living subject's skin and positioning a tonometry pressure sensor on the artery location for tonometric blood pressure measurement to obtain pressure pulse data for a subject. In operation according to embodiments, measurement logic of a measurement validation system may utilize the pressure pulse data to extract blood pressure data, heart rate data, blood pressure variability data, and heart rate variability data. The foregoing data may be utilized in identifying whether the blood pressure measurement properly and accurately reflects the situation of the subject.

Abstract: A method for determining an artery location on a living subject's skin and positioning a tonometry pressure sensor on the artery location for tonometric blood pressure measurement is provided. The method comprises a non-contact optical search followed by a contact pressure search. In the non-contact optical search, an optical-sensing unit is used to scan the skin along a scan path while maintaining a pre-determined distance between the unit and the scan path. A search region within the scan path and a height profile characterizing the scan path's curvature are determined. The search region is determined such that an artery is predicted to lie thereunder. The artery location is then searched within the search region by the contact pressure search, in which the pressure sensor sweeps along the search region and the sweeping is guided by curvature information provided by the height profile. A device using the method is also provided.

Abstract: The present invention is a blood pressure measuring device comprising an optical sensing unit adapted for detecting optical pulses at a plurality of locations on an external surface of a user. The device also comprises a processing unit coupled to the optical sensing unit for determining an optimal location from the plurality of locations based on the detected optical pulses and a pressure sensing unit adapted for detecting a pressure pulse of the user at a location of measurement. The present invention also discloses a method of measuring a blood pressure of a user using a blood pressure measurement device. The advantage of the present invention is that by using an optical sensing unit to locate the artery of the user, or to compensate the misalignment from the artery, the blood pressure is more accurately determined. With the calibration method, the deficient cuff calibration can be waived in certain circumstances.
