  • Patent number: 8801621
    Abstract: A pulse wave data analyzing method includes successively detecting bottom and top peak values of pulse wave data along a time axis, calculating successive bottom-to-top amplitude values along the time axis, and comparing first and second peak-to-peak amplitude values occurring in succession along the time axis. If the ratio of the second peak-to-peak amplitude value to the first peak-to-peak amplitude value is smaller than a preset threshold, the bottom and top peak values related to the second peak-to-peak amplitude value are classified as temporarily erased data. The second peak-to-peak amplitude value is compared with a third peak-to-peak amplitude value occurring immediately thereafter and, if the ratio between the second and third peak-to-peak amplitude values is larger than the threshold, the temporarily erased data is restored. If the ratio between the second and third peak-to-peak amplitude values is not larger than the threshold, the temporarily erased data is completely erased.

  • Patent number: 8600468
    Abstract: A biometric information measuring apparatus has a storage device for storing data concerning a biometric signal or biometric information derived from the biometric signal in association with position information indicating the current location of a sensor unit of the apparatus. Since the biometric information measuring apparatus provides the position information acquired when the data on the biometric signal or the biometric information was obtained, one can know the location and behavior of a subject at the time of measurement and exactly analyze the biometric information on the subject.
