Abstract
The present disclosure provides a vital sign measuring device and method that may measure a heart rate signal of a living body in a motion state. The method comprises detecting two different signals, using an adaptive noise removal algorithm for removing noise from the two signals, and obtaining a more accurate heat rate signal after a certain operation.
Claims26
A device, comprising:
- a first signal source located at a first place, wherein the first signal source is configured to emit a first light beam to a surface of a living body;
- a first signal detecting device located at a second place, wherein the first signal detecting device is configured to detect a first signal reflected by the living body, the first signal being associated with the first light beam;
- a second signal detecting device located at a third place, wherein the second signal detecting device is configured to detect a second signal reflected by the living body, the second signal being associated with the first light beam but different from the first signal;
- and
- a processor configured to determine a vital signal of the living body based on the first signal and the second signal.
