  • Publication number: 20180333102
    Abstract: The present invention relates to a device, system and a method for determining vital sign information of a subject. To provide an increased signal quality and an improved robustness of the obtained vital sign information with respect to motion and low SNR, the proposed device tries to find the linear combination of the color channels, which suppresses the distortions best in a frequency band including the pulse rate, and consequently use this same linear combination to extract the desired vital sign information (e.g. represented by a vital sign information signal such as a respiration signal or Mayer waves) in a lower frequency band.

  • Publication number: 20180070840
    Abstract: A two-state wearable device may include a wearable band (e.g., a watch band) and a display module (e.g., a watch face). In a “detached” state, the wearable band and display module act as separate devices, and the display module can be charging its battery while the wearable band gathers sensor data (e.g., sleep tracking data) and provides a vibrating/audio alarm clock function. In an “attached” state, the wearable band and display module act together as a single device, meaning that the data collected by the wearable band during the “detached” state is sent to and stored at the display module, and that sleep settings input at a user interface of the display module impact the wearable band's alarm function. The display module may also use its newly-recharged battery to recharge the wearable band's battery so that it can be used the next night.
