1. A method of determining heart rate of a person during exercise comprising:
- positioning a plurality of heart beat sensors at respective locations on a body part of the person, a circular support member circumferentially engaging the body part of the person, the plurality of heat beat sensors including;
three light emitters spaced at 120°
intervals on a circumference of the circular support member emitting light into respective areas of tissue of the body part, anda plurality of light detectors on the circumference of the circular support member and respectively detecting the light emitted by the three light emitters that is reflected from the respective areas of tissue of the body part;
obtaining a plurality of sensor signals from the heart beat sensors, the sensor signals comprising heart beat signals and movement signals,comparing the sensor signals to separate the heart beat signals and the movement signals from the sensor signals, anddetermining heart rate from the heart beat signals.

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