  • Publication number: 20150335274
    Abstract: A physiological signals detection device has a light source connecting to a control unit, a light detector and a processing unit. The light detector has a pixel sensor array including multiple light sensing elements. The light source emits light through a lens to the human body to generate reflected light. The light detector receives the reflected light to generate a sensing signal. Since the light sensing elements respectively receive different reflected light from different directions, the light sensing elements receiving reflected light from the noise are easily selected and eliminated from calculating the physiology value. Therefore, the calculated physiology value is more accurate.

  • Publication number: 20150305635
    Abstract: A portable electronic device uses the initial heartbeat value to calculate a possible heartbeat variation. Then a reference range is determined. Only the real time heartbeat value falling in the reference range is output as a correct real time heartbeat value. Thus, the too large or too small erroneous heartbeat values influenced by the vibration noise are eliminated to precisely output the correct real time heartbeat value. Therefore, the extra vibration sensors need not to be installed to lower the cost and to reduce the volume.
