Abstract: A device including an array of electrodes generates one or more electrical signals from a user, extracts one or more noise signals, and generates one or more de-noised electrical signals upon processing the electrical signal(s) with the noise signal(s). The array of electrodes is coupled to a surface of the device, where the device also includes force sensors in mechanical communication with the surface for detecting user weight and other forces. The device can be configured to generate electrical signals from different subportions of the array of electrodes and to extract noise signals from different subportions of the array of electrodes, where the subportion(s) for electrical signal generation may or may not overlap with the subportion(s) of electrodes for noise signal extraction.

Abstract: Disclosed herein are systems, methods and a computer readable storage medium that determine an individual's movement during sleep. In some embodiments, the identification is based on data from a motion sensor included in wearable device. In some embodiments, the individual wears the wearable device on his wrist during the individual's resting and/or sleep activities. In some embodiments, the system, methods and the computer readable storage medium automatically identify the various (stages) types of sleep during an individual's sleep periods that include periods of REM sleep, deep sleep, and light sleep and that are indicative of the individual's overall well-being and health.
