    Abstract: A wearable device that attaches to a body part of a user via an attachment member operates in at least a connected and a disconnected state. One or more sensors located in the wearable device and/or the attachment member detect the user's body part when present. Such detection may only be performed when the attachment member is in a connected configuration and may be used to switch the wearable device between the connected and disconnected states. In this way, the wearable device operates in the connected state when worn by a user and in the disconnected state when not worn by the user.

    Abstract: A device for determining a heart rate of a user has a PPG sensor and an accelerometer to compensate for acceleration artifacts within the PPG signal. The device transforms time domain PPG and accelerometer signals into the frequency domain using a Fourier transformation and utilizes the Fourier coefficient magnitudes as indicative of the probability of candidate heart rate values. Candidate heart rate values are determined at sampling times over a time interval and a most probable heart rate path during the time interval is determined using a reward/penalty algorithm.

    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: The present embodiments provide a system that dynamically controls power consumption in a computing device. During operation, the system measures the performance of the computing device while executing a work-loop. Next, the system determines a derived completion time for the work-loop based on the measured performance. (For example, the derived completion time can be an expected completion time, a maximum completion time, or more generally a completion time distribution.) The system then determines a deadline-proximity for the work-loop based on a comparison between the derived completion time and a deadline for the work-loop. (For example, the deadline-proximity can be an expected deadline-proximity, a minimum deadline-proximity, or more generally a deadline-proximity distribution.) Finally, the system controls the power consumption of the computing device based on the determined deadline-proximity for the work-loop.
