APPARATUS FOR MEASURING BIO-INFORMATION AND A METHOD FOR ERROR COMPENSATION THEREOF
First Claim
1. An apparatus for measuring bio-information, the apparatus comprising:
- a heart rate sensor unit configured to measure heart rates by receiving a light that has entered and come out from skin;
an acceleration sensor unit configured to output a step count by measuring the step count of a wearer;
a display unit configured to display the measured heart rates and step count; and
a wrist-wearable connection unit configured to electrically connect the heart rate sensor, the acceleration sensor unit and the display unit.

Abstract
The present disclosure relates to an apparatus for measuring bio-information, the apparatus including a heart rate sensor unit configured to measure heart rates by receiving a light that has entered and come out from skin, an acceleration sensor unit configured to output a step count by measuring the step count of a wearer, a display unit configured to display the measured heart rates and step count, and a wrist-wearable connection unit configured to electrically connect the heart rate sensor, the acceleration sensor unit and the display unit, whereby heart rate can be accurately measured using a line light source instead of point light source, even if the apparatus is not fully attached to a wrist. The apparatus includes a heart rate sensor unit configured to improve a light receiving efficiency using four light receiving units.

10. A method for error compensation in a heart rate sensor including a first light receiving unit arranged at an upper left surface of a line light source, a second light receiving unit arranged at an upper right surface of the line light source,
a third light receiving unit arranged at a bottom left surface of the line light source, and a fourth light receiving unit arranged at a bottom right surface of the line light source, the method comprising: -
detecting an error by comparing light signals received by the first to fourth light receiving units; multiplying a predetermined weight to a greater light signal as a result of comparison of the light signals when the error is generated; and adding a size of a light signal multiplied by the weight to a size of a light signal not multiplied by the weight. - View Dependent Claims (11, 12, 13)
