Abstract: An example technique may include tracking motion of a user wearing the wearable device using at least first sensors of one or more sensors of the wearable device. The technique may also include tracking a physical state of the user using at least second sensors of the one or more sensors of the wearable device. The technique may also include determining whether an application of the wearable device has been launched. The technique may also include determining an action category of the user based at least in part on at least one of the motion of the user, the physical state of the user, or whether the application has been launched. The technique may also include collecting heartrate data of the user. The technique may also include categorizing the heartrate data based at least in part on the determined action category.

Abstract: A breathing sequence may define a suggested breathing pattern. Based on signal data collected by a user device, an initial breathing pattern that includes a cyclic pattern may be estimated. A first period of the breathing sequence may be initiated by generating a breathing sequence element based on a synchronization of the cyclic pattern with the breathing sequence. The breathing sequence element may fluctuate during a second period of the breathing sequence in accordance with a breathing profile associated with the suggested breathing pattern.

Abstract: Embodiments are directed to systems and methods for determining a cardiac burden of a user. Methods include collecting a series of cardiac measurements at a first set of time points using one or more sensors and determining a set of measured data points. Each measured data point can include a time value from the first set of time points and a classification comprising one of an occurrence of a qualified cardiac event or absence of the qualified cardiac event. Methods include generating a set of additional data points each including a time value from the second set of time points and a classification of one of the occurrence of the qualified cardiac event or the absence of the qualified cardiac event. Methods include determining a value of the cardiac burden for a predefined period of time using the set of measured data points and the set of additional data points.

Abstract: A configuration for a breathing sequence may be defined using a hardware element of a user device. A user interface of the user device may be used to begin the breathing sequence. During the breathing sequence, a fluctuating progress indicator user interface element may fluctuate at a cyclic rate. Such fluctuation may include repeated growing and repeated shrinking of the fluctuating progress indicator user interface element. During the breathing sequence, heart rate data may be collected and used to present heart rate information at a conclusion of the breathing sequence.

Abstract: Techniques are provided for tracking heartrate metrics using different operating modes associated with different contexts of a wearable device. For example, a heartrate sensor of the wearable device may be operated in a first operating mode when an activity is being tracked within an application session of a particular application. The heartrate sensor may be operated in a second operating mode after detecting conclusion of the activity within the activity session (e.g., during sedentary time).

Abstract: This relates to methods for measuring irregularities in a signal and corresponding devices. The devices can include a PPG sensor unit configured to detect multiple occurrences of a given event in the measured signal(s) over a sampling interval. In some instances, the device can register the occurrences of the events. In some examples, the device can include one or more motion sensors configured to detect whether the device is in a low-motion state. The device may delay initiating measurements when the device is not in a low-motion state to enhance measurement accuracy. Examples of the disclosure further include resetting the sample procedure based on one or more factors such as the number of non-qualifying measurements. In some examples, the device can be configured to perform both primary and secondary measurements, where the primary measurements can include readings using a set of operating conditions different from the secondary measurements.

Abstract: An algorithm for determining heart rate by removing motion artifacts from a PPG signal in the frequency domain utilizes a principal component analysis. Some examples of the present disclosure process PPG signals in combination with accelerometer signals to remove unwanted artifacts in the frequency domain. For example, principal components of the accelerometer signal can be generated and combined with the PPG signal to filter out acceleration contributions represented in the PPG signal to reveal heart rate peaks. Additionally, in some examples, templates may be stored for correlation with candidate heart rate peaks to select those peaks with the highest correlations with the stored templates.

Abstract: Algorithms for detecting whether a device is properly secured to a user's skin are described. The operation of a device, such as a wearable device, can be adjusted based on whether the device is properly secured to a user's skin (e.g., on-wrist) or not properly secured to the user's skin (e.g., off-wrist). For example, certain functions can be disabled for power-saving, security or other purposes if the device is off-wrist. In order to avoid falsely identifying the device as off-wrist or on-wrist, algorithms for detecting whether the device is on-wrist or off-wrist can calculate one or more variances based on signals measured by a light sensor and compare the one or more variances with one or more thresholds. Comparing the one or more variances to the one or more threshold can improve the accuracy of wrist-detection algorithms.

Abstract: A configuration for a breathing sequence may be defined using a user interface of a user device. The user interface may also be used to begin the breathing sequence. Prior to beginning the breathing sequence, the user device can determine a breath ratio for the breathing sequence based on a breathing profile. The breath ratio is based at least in part on inhale time and exhale time of a breath of the breathing sequence. During the breathing sequence, a fluctuating user interface element may fluctuate at a cyclic rate corresponding to the breath ratio. Such fluctuation may include repeated growing and repeated shrinking of the fluctuating user interface element.
