Abstract: An analysis apparatus is provided with: a light emitting part, a light dispersing part, a light detecting part, a storage unit, and a control unit. The light dispersing part disperses first reflected light reflected from a food product when the food product has been irradiated with light from the light emitting part. The light detecting part: generates first detection data by detecting the first reflected light dispersed; and, when a food product sample containing known ingredients is irradiated with light from the light emitting part, generates second detection data by detecting second reflected light reflected from the food product sample and dispersed by the light dispersing part. The storage unit stores a regression formula computed using the second detection data as a parameter. The control unit estimates the ingredients contained in the food product using the first detection data and the regression formula stored in the storage unit.

Abstract: A biological information measurement device includes a pulse wave detector having a light emitter for irradiating a living body with light and a light receiver for receiving reflected light of the light emitted from the living body when the light emitter irradiates the living body with the light, and detecting pulse wave information of the living body based on the reflected light received in the light receiver; an operator for determining an autonomic nerve function based on the pulse wave information of the living body detected by the pulse wave detector; and a controller configured so as to control the pulse wave detector and the operator. The pulse wave detector, the operator, and the controller are provided in a measuring device main body case.

Abstract: A circulatory function measurement device that accurately measures a subject's circulatory function. A pulse wave accumulated value calculation unit calculates a pulse wave accumulated value by accumulating the amplitude values of pulse waves in chorological order as the compressing pressure changes. A blood vessel hardness measurement unit measures blood vessel hardness based on the relationship between the calculated pulse wave accumulated value and the compressing pressure.
