    • An apparatus for measuring a concentration of a light-absorbing substance in blood is disclosed. A light emitter emits light beams to irradiate a living tissue, each of the light beams being associated with one wavelength which is absorbed by the blood. A first instrument measures first intensities of the light beams, which are to be incident on the living tissue. A second instrument measures second intensities of the light beams, which are transmitted through the living tissue. A first calculator calculates an attenuation variation ratio, which is a ratio of attenuation variations of the respective light beams due to variation of a volume of the blood caused by pulsation, based on the second intensities of the light beams. A second calculator calculates the concentration based on the first intensities, the second intensities, and the attenuation variation ratio.
    • 公开了一种用于测量血液中光吸收物质浓度的装置。 光发射器发射光束以照射活组织,每个光束与由血液吸收的一个波长相关联。 第一个仪器测量将要入射到活体组织上的光束的第一强度。 第二种仪器测量透过活组织的光束的第二强度。 第一计算器基于光束的第二强度计算衰减变化比,其是由于由脉动引起的血液的体积的变化引起的各个光束的衰减变化的比率。 第二计算器基于第一强度,第二强度和衰减变化率来计算浓度。

    • In an apparatus adapted to measure a pulse rate of a subject, a plurality of band pass filters, each of which has a center frequency that is different from the others are provided. The band pass filters are connected in parallel to one another so as to be adapted to receive a first signal corresponding to a pulse wave of the subject and be operable to output a plurality of second signals each of which is obtained by filtering the first signal with each center frequency. A first processor is operable to obtain a fundamental frequency of the first signal. A selector is operable to select one of the second signals which is output from one of the band pass filters having such a center frequency that is closest to the fundamental frequency. A second processor is operable to calculate the pulse rate from the selected one of the second signals.
