Abstract: A method, medium, and apparatus for measuring a heart rate from blood flow in a blood vessel of a human body part, including: an amplifying circuit receiving a light signal reflected or penetrated from a human body part and generating a multi-stage amplified signal made up of a plurality of signals with a corresponding different gains; and a processor separating the multi-stage amplified signal into a plurality of channel signals having corresponding gains, reconfiguring the light signal using a channel signal selected among the plurality of channel signals and calculating the heart rate from the reconfigured light signal. Accordingly, it is possible to make an accurate measurement of a heart rate by minimizing effects of measuring environments. In addition, the apparatus, method, and medium are resistive to noise resulting from a movement of a human body part by comparing an optimum signal pattern and a correlation coefficient.

Abstract: There is provided an apparatus and method for correcting location information of a mobile body and a computer-readable recording medium storing at least a computer program for controlling the apparatus. The apparatus for correcting the location information of the mobile body, the location information regarding at least one of a location and an azimuth angle of the mobile body, includes a beam generator generating at least one beam; and a location information correcting unit receiving measured location information, sensing the generated beam, and correcting the received measured location information using the sensed beam, wherein the location information correcting unit is installed in the mobile body. Therefore, it is possible to easily correct location information of a mobile body using beams and more accurately correct the location information without accumulating errors, differently from a conventional dead reckoning system.
