A variable value calculating process includes: measuring a propagation time of the propagation of an ultrasound wave through a measurement sector inside a housing; obtaining a temperature calculated value on the basis of the measured value of the propagation time and a reference distance for the measurement sector; obtaining a temperature measured value by measuring the temperature inside the housing; and obtaining a temperature replacement fluctuation value indicating a difference between the temperature calculated value and the temperature measured value. The variable value calculating process is executed for each of a plurality of temperature conditions under which the temperature of a reference gas inside the housing differs. A temperature compensation table in which the temperature of a gas to be measured is associated with a temperature compensation value relating to the temperature is obtained on the basis of the temperature replacement fluctuation values obtained under each temperature condition.

Abrégé

The objective of the present invention is to improve the measuring accuracy of a gas concentration measuring device. A variable value calculating process includes: a step of measuring a propagation time of the propagation of an ultrasound wave through a measurement sector inside a housing 10; a step of obtaining a temperature calculated value on the basis of the measured value of the propagation time and a reference distance for the measurement sector; a step of obtaining a temperature measured value by measuring the temperature inside the housing 10; and a step of obtaining a temperature replacement fluctuation value indicating a difference between the temperature calculated value and the temperature measured value. The variable value calculating process is executed for each of a plurality of temperature conditions under which the temperature of a reference gas inside the housing 10 differs. A temperature compensation table in which the temperature of a gas to be measured is associated with a temperature compensation value relating to the temperature is obtained on the basis of the temperature replacement fluctuation values obtained under each temperature condition.

Abrégé

[Problem] To develop a novel method and device that can monitor respiration and/or pulse changes in various kinds of animals including humans that are in a variety of positions such as during sleep or during exercise with high sensitivity. [Solution] A method for monitoring changes in either or both the respiration and pulse of an animal and a device used for implementing said monitoring method. The method comprises: a process of vibrating a piezoelectric vibrator by continuously or intermittently applying an AC voltage of a frequency corresponding to the characteristic resonance frequency of the piezoelectric vibrator on the piezoelectric vibrator with the piezoelectric vibrator pressed directly or indirectly in contact with the surface of the animal's body; a process of extracting the current generated by the piezoelectric vibrator that is vibrating; and a process of calculating the impedance of the piezoelectric vibrator from the value of said current and the value of the AC voltage applied on the piezoelectric vibrator and continuously or intermittently detecting the changes in the impedance over time.
