Abstract: A gait posture meter that evaluates a gait posture of a measurement subject includes an accelerometer affixed to a centerline of the measurement subject's waist area and a computation unit. The computation unit calculates a Z feature amount and an X feature amount indicating a degree of a difference between up-down and front-rear axis direction accelerations of the waist area in a left leg reference period and up-down and front-rear axis direction accelerations of the waist area in a right leg reference period using a timewise change waveform in three axis accelerations outputted by the accelerometer, and calculates a Y feature amount indicating a degree of a difference between a displacement of a left-right axis direction trajectory of the waist area in the left leg reference period and a displacement of the left-right axis direction trajectory of the waist area in the right leg reference period by finding a second-level integration of the left-right axis acceleration outputted by the accelerometer.

Abstract: A pulse wave signal expressing a pulse is obtained by detecting a pulse of a measurement subject using a pulse wave sensor. The pulse wave signal is stored in a storage unit. A frequency spectrum of the pulse wave signal is found by converting the time-domain pulse wave signal stored in the storage unit into the frequency domain. It is determined whether or not the measurement subject is at rest by finding a frequency range, within a predetermined total frequency range the pulse rate of a person can take on, in which an intensity of a frequency component of the frequency spectrum exceeds a first threshold, and finding whether or not a ratio of the frequency range with respect to the total frequency range is less than a second threshold. A pulse rate from the point in time when the measurement subject has been determined to be at rest is found as the measurement subject's at-rest pulse rate.

Abstract: A biometric antenna device of the present invention includes: a conductor layer configured to face the measurement site for emitting and/or receiving the radio wave; and a dielectric layer mounted along a facing surface facing the measurement site of the conductor layer or of a base material mounting the conductor layer and extending in parallel with the conductor layer, the dielectric layer having a predetermined relative permittivity. The dielectric layer keeps a distance between an outer surface of the measurement site and the conductor layer constant, in a mounted state in which a second surface on a side opposite to a side of a first surface on a side along the conductor layer of the dielectric layer abuts on an outer surface of the measurement site.

Abstract: An antenna device for biological measurement according to the present invention includes a belt to be worn as surrounding a measurement target site of a living body. A transmission/reception antenna group is provided to the belt and includes a plurality of antenna elements. In a wearing state where the belt is worn as surrounding an outer surface of the measurement target site, a radio wave is emitted toward the measurement target site using any one of the antenna elements as a transmission antenna. A reflected radio wave is received using any one of the antenna elements as a reception antenna. A transmission/reception antenna pair formed of the transmission antenna and the reception antenna is selected by switching or weighted among the plurality of antenna elements based on a reception output.

Abstract: An ultrasonic vibrator driving apparatus applies a sine-waveform alternating voltage as a drive voltage via a conversion circuit to an ultrasonic vibrator that has a unique resonance frequency. A first current detector that detects a first current that flows from the drive voltage generator to the conversion circuit and a second current detector that detects a second current that flows from the conversion circuit to the ultrasonic vibrator are included. A frequency controller performs control on the drive voltage generator to change the frequency of a square-waveform alternating voltage so that the difference between the first current and the second current is reduced or approaches a minimum.
