Abstract: A method for estimating blood pressure using a blood flow occlusion system applied to an artery includes receiving from a first sensor a sensed signal; processing at a processor the sensed signal to detect beats in a pulsatile signal; determining validity of the detected beats; storing the detected beats and data associated with the detected beats in the sensed signal as the pressure applied to the artery by the blood flow occlusion system deflates towards a level below a nominal level; determining baseline beat characteristics; evaluating the stored beats and associated data to detect change in beat characteristics as compared to the baseline beat characteristics; selecting a beat before the detected change in the beat characteristic as the last beat indicating the onset of the diastolic blood pressure for the artery; determining a value of the applied pressure at the last beat as the diastolic blood pressure for the artery.

Abstract: A method includes receiving multimodal data collected using at least one wearable device during an assessment window. The method also includes extracting biomarker features from the multimodal data, based on changes in the extracted biomarker features. The method also includes detecting that a stress event occurred during the assessment window. The method also includes accessing a plurality of templates of patterns in biomarker features, wherein a first subset of the templates is associated with unhealthy response to stress and a second subset of the templates is associated with healthy response to stress. The method also includes determining whether the stress event corresponds to a healthy response or an unhealthy response based on similarities between a pattern in the extracted biomarker features and the plurality of templates. The method also includes responsive to the stress event corresponding to an unhealthy response, providing a stress management recommendation.

Abstract: A method and device for measuring a biological variable are provided. The method of measuring the biological variable may include detecting an infrared signal which is irradiated toward a body part and is reflected therefrom, extracting spectrum data from the detected infrared signal, obtaining intensity data corresponding to a preset frequency from the extracted spectrum data, obtaining a biological information-measuring model by performing multiple linear regression (MLR) on the obtained data, and measuring a biological signal of the body part by using the obtained biological information-measuring model.

Abstract: In one embodiment, a method includes recording, by a camera of a client device, a video of a region of a first user's skin and estimating, from the recorded video, a current ratio of ratios (RoR) for the first user corresponding to the first user's current blood-oxygen saturation. The method further includes converting the first user's determined RoR to a transformed RoR for the first user based at least in part on a baseline user's RoR determined while generating a trained SpO2 prediction model. The trained SpO2 prediction model is trained to estimate the baseline user's SpO2 value based on an input RoR value from the baseline user. The method further includes determining, by the trained SpO2 prediction model and based on the transformed RoR for the first user, the first user's current estimated blood-oxygen saturation.

Abstract: A method includes capturing a video of a person's face using a camera. The method also includes determining a motion-based respiratory rate (RR) and a motion-based respiratory signal based on the video of the person's face. The method further includes determining a remote photoplethysmography (rPPG)-based RR and an rPPG-based respiratory signal based on the video of the person's face. The method also includes predicting whether the motion-based RR or the rPPG-based RR is more likely to be accurate using a trained machine learning model that receives the motion-based respiratory signal and the rPPG-based respiratory signal as input. In addition, the method includes presenting one of the motion-based RR or the rPPG-based RR based on the prediction.

Abstract: In one embodiment, a method includes accessing a window of motion data collected by a motion sensor of a device worn by a user and selecting motion data in the window about or more particular axes of the motion sensor. The method further includes determining a ballistocardiogram (BCG) signal in the selected motion data and determining whether the BCG signal in the selected motion data satisfies a signal-quality metric. If the BCG signal in the selected motion data satisfies the signal-quality metric, then the method includes (1) determining one or more heart-beat metrics of the user from the selected motion data; and (2) estimating, based on the one or more determined heart-beat metrics, a stress condition of the user at a time coincident with the window of motion data.
