  • Patent number: 10426408
    Abstract: A signal detection device includes a measurer, an arithmetic operation unit, and signal period detector, and detects information such as a cardiac cycle with high accuracy by causing resonance of only a signal such as a heartbeat, the signal having strong pulse characteristics. The measurer measures a signal. The arithmetic operation unit performs nonlinear arithmetic operation processing for amplifying a pulse-like component of the signal measured by the measurer and suppressing a component other than the pulse-like component of the signal measured by the measurer. The signal period detector detects a periodic signal from an output of the arithmetic operation unit.

  • Publication number: 20190269350
    Abstract: A respiratory state estimation apparatus estimates whether a respiratory state is equivalent to a first respiration including normal respiration or a second respiration smaller in respiratory ventilation volume than the first respiration. The apparatus includes an acquisition unit, a detector, a calculator, and an estimator. The acquisition unit acquires an electrocardiographic waveform of a user. The detector detects amplitudes of R waves in the electrocardiographic waveform. The calculator calculates a spectrum of the amplitudes by performing transform processing with respect to the amplitudes in a time width in which the spectrum has a spectrum shape with a peak in the first respiration and a spectrum shape without a peak in the second respiration. The estimator estimates a respiratory state of the user based on the spectrum.
