A computer implemented method and system are provided for detecting premature ventricular contractions (PVCs) in cardiac activity. The method and system obtain cardiac activity (CA) signals for a series of beats, and, for at least a portion of the series of beats, calculate QRS scores for corresponding QRS complex segments from the CA signals. The method and system calculate a variability metric for QRS scores across the series of beats, calculate a QRS complex template using QRS segments from the series of beats, calculate correlation coefficients between the QRS complex template and the QRS complex segments, compare the variability metric to a variability threshold and the correlation coefficients to a correlation threshold, and designate the CA signals to include a predetermined level of PVC burden based on the determining.

Disclosed are a massage device providing a tinnitus treatment program and a control method therefor. According to an embodiment of the present disclosure, disclosed is a method by which a massage device provides a tinnitus treatment program. The method by which the massage device provides the tinnitus treatment program comprises the steps of: obtaining tinnitus information about a user; adjusting the magnitude of at least some of a plurality of frequency components included in a raw sound source and then flattening the raw sound source, so as to generate a first processed sound source; reducing the magnitude of at least some of a plurality of frequency components included in the first processed sound source on the basis of the obtained tinnitus information, so as to generate a tinnitus treatment sound source; and providing a tinnitus treatment program in which the generated tinnitus treatment sound source and tinnitus treatment massage are combined.

The wake-up detection device may include a sensor configured to detect a movement of a person and a biosignal of the person; and a controller configured to analyze the movement and the biosignal recognized by the sensor, and determine whether the person wakes up from sleep, on the basis of a result of analyzing the movement and the biosignal. The controller may determine a change in a heart rate of the person when the person converts from a sleep state to a non-sleep state, and when it is determined that the change in the heart rate and the movement of the person increase, the controller may output a first alarm.

Systems and methods for enhancing wellness in a habitable space are provided. In some forms, an example system for enhancing wellness in a habitable space includes a control system having a processor, communication circuitry, and a memory. The communication circuitry of the control system is configured to communicate with one or more devices positioned within the habitable space. One or more sensors may also be positioned proximate the habitable space to detect indicia (e.g., biometric characteristics of a user, behavioral characteristics of a user, and environmental characteristics) and communicate the detected indicia to the control system. Based at least in part on the detected indicia, the control system is configured to trigger initiation of a scene in the habitable space by communicating a signal to at least one of the devices in the habitable space to adjust operation thereof.

Systems and methods for providing a user characteristic to a service provider for a virtual conference with a user are provided. In particular, a computing device may collect raw media data associated with the user during the virtual conference between the user and the service provider. During the virtual conference, the computing device may perform a first processing of the raw media data to extract intermediate user data, wherein the intermediate user data comprises one or more of a physiological signal and a behavioral signal associated the user. The computing device may further transform the raw media data into transformed media data and transmit the transformed media data with the intermediate user data to a server for second processing of the intermediate user data.

A prediction method and system of a low blood pressure is provided, including: obtaining a plurality of feature sequence values; selecting two of the feature sequence values from the feature sequence values according to a time ratio relationship; calculating a relation coefficient according to the selected two feature sequence values by a weighting process; repeating to select the new feature sequence values and the corresponding relation coefficient and to assign the new feature sequence values and the relation coefficient into the input group until the feature sequence values conforming to the time ratio relationship are traversed; and obtaining a training result by substituting the input group into a low blood pressure prediction model.

A method of measuring noninvasive blood pressure includes determining a window for pulse detection for a patient, receiving a pressure signal measured from a measure sensor in a blood pressure cuff, and setting a pulse detection period for each heart beat based on the window and a heart beat indicator indicating at least one heart beat time for the patient. The pressure signal is then examined within each pulse detection period to identify a pressure peak therein. A blood pressure for the patient is determined based on the pressure peaks detected in the pressure signal.

In order to help reduce the effects of motion sickness, there is provided a method for reducing motion sickness in a subject which comprises acquiring a sequence of video images, extracting measurements of a heart-rate of the subject over a first period of time from the sequence of video images using photoplethysmography (PPG), calculating at least one trend in the measurements, determining a presence of motion sickness when the at least one trend is positive over a first time window, the first time window being included in the first period of time, and generating an event arranged to generate a corrective action. It is often possible to detect the onset of motion sickness before the subject actually feels the symptoms. Indeed, by the time the symptoms appear, corrective action is much less effective. Therefore, by detecting the onset early and alerting the subject so that they can react, it is possible to avoid the attack of motion sickness or, at least, reduce significantly its effects.
