Abstract: A biological detection device includes a signal acquirer that acquires a signal including a heartbeat, an analyzer that performs a frequency analysis of the signal to generate a spectrogram, an integrated value calculator that integrates energy of a heartbeat frequency component, which is a frequency component corresponding to the heartbeat, among frequency components of the signal shown by the spectrogram and calculates an integrated value, a peak specifier that specifies peaks, which are maximum values, in the integrated value, a peak set generator that combines, among the peaks, a first peak and a second peak, which occurs in a later time than the first peak, and generates a peak set, and a selector that selects, from the peak set, a sequence having highest likelihood in a maximum likelihood estimation method.

Abstract: A biological detection device includes a signal acquirer that acquires a signal including a respiration component, a filter that attenuates a frequency component other than the respiration component included in the signal and generates a post-processing signal, an analyzer that analyzes the post-processing signal to generate a spectrogram, a variation calculator that calculates variation of energy in a predetermined frequency band in energy of the frequency component indicated by the spectrogram, a first determiner that determines whether the variation is larger than a threshold, a second determiner that, if it is determined by the first determiner that the variation is not larger than the threshold, determines whether a higher harmonic wave with respect to a second peak having energy equal to or more than a predetermined ratio to a first peak where the energy is maximum is present in the predetermined frequency band, and an output unit that outputs a respiration rate based on a frequency of the first peak if

Abstract: A signal representing heartbeat behavior is accurately restored. The present signal restoration system includes: a signal acquirer configured to acquire a first heartbeat signal representing heartbeat behavior; a first band-pass filter configured to generate a first signal by performing first band-pass filter processing on the first heartbeat signal; an integral calculator configured to calculate an integral value by integrating frequency intensity of the heartbeat represented by the first signal; a second band-pass filter configured to generate a third signal by performing second band-pass filter processing on a second signal representing the integral value with respect to time; and a restored signal generator configured to generate a restored signal representing heartbeat behavior based on first data generated by dividing the third signal at intervals of a predetermined time.

Abstract: An object is to accurately determine the presence or absence of a living body. A living body detection device comprises: a signal acquirer that acquires a first signal including a first frequency component that is a frequency component of heartbeat and a second frequency component that is a frequency component of breathing; a filter that attenuates a frequency component higher than the first frequency component based on the first signal to generate a second signal; a frequency analyzer that analyzes a frequency component of the second signal; a variance value calculator that calculates a first variance value of energy of at least one of the first frequency component and the second frequency component based on a result of analysis by the frequency analyzer; a first statistical quantity calculator that calculates a first statistical quantity of the first variance value for a predetermined period; and a determiner that determines presence or absence of a living body based on the first statistical quantity.

Abstract: It is an object to improve the accuracy of detecting breathing. The present system for detecting breathing comprises: a transmission unit that transmits radio waves to a plurality of positions including a position at which a subject is present; a reception unit that receives reflected waves as a result of reflection of the radio waves; a phase fluctuation calculator that calculates phase fluctuation of the reflected waves; a generator that performs a Fourier transform on the phase fluctuation and generates a spectrogram indicating a relationship between a time at which the reflected waves are received and a frequency component included in the reflected waves; and a breathing rate estimator that estimates a breathing rate of the subject by outputting a probability that the subject takes breaths at a predetermined frequency for each frequency based on the spectrogram and calculating a weighted average of the frequency by using the probability as a weight.
