Exercise Device, Sensor and Method Of Determining Body Parameters During Exercise

摘要

A noninvasive light sensor for detecting heart beat signals has a circular support member engageable circumferentially with a body part of a person. There are a plurality of light emitters and light detectors located around a circumference of the circular support member for respectively emitting light signals into different areas of tissue surrounding the body part, and receiving reflected light signals from the different areas of tissue surrounding the body part.

1. A method of determining heart rate of a person during exercise comprising:
positioning a circular support member circumferentially engaging the body part of the person; a plurality of light emitters spaced on a circumference of the circular support member emitting light into respective areas of tissue of the body part; a plurality of light detectors on the circumference of the circular support member and respectively detecting the light emitted by the of plurality of light emitters that is reflected from the respective areas of tissue of the body part; obtaining at least three sensor signals from the plurality of light detectors, the sensor signals comprising heart beat signals and movement signals, separating the heart beat signals and the movement signals in the at least three sensor signals; and determining heart rate from the heart beat signals.
