Exercise Device

Abstract

An exercise device includes an ear piece insertable within the ear canal along an ear canal axis, a plurality of light emitters located about a periphery of the ear piece and spaced apart at 120° intervals for emitting light signals perpendicular to the ear canal axis into different areas of tissue surrounding the ear canal, a plurality of light detectors located about the periphery of the ear piece for detecting reflected light signals from the different areas of tissue surrounding the ear canal, an audio speaker, an audio player for sending audio signals to the audio speaker, and a vital sign monitor for determining at least one of heart rate, blood oxygen level, and body temperature from signals of the emitters and detectors.

1 . An exercise device comprising:
 an ear piece insertable within the an ear canal along an ear canal axis;   a plurality of light emitters located about a periphery of the ear piece and spaced apart at one hundred and twenty degree intervals for emitting light signals perpendicular to the ear canal axis into different areas of tissue surrounding the ear canal;   a plurality of light detectors located about the periphery of the ear piece for detecting reflected light signals from the different areas of tissue surrounding the ear canal;   an audio speaker, an audio player for sending audio signals to the audio speaker; and   a vital sign monitor that for determining at least one of heart rate, blood oxygen level, and body temperature from signals of the emitters and detectors.
