  • Patent number: 8585615
    Abstract: An abdomen width determiner determines an abdomen width of a subject. A shape index calculator calculates a shape index corresponding to a cross-sectional shape of an abdomen of the subject. An obesity evaluator evaluates whether an obesity degree of the subject is high or low. An obesity index calculator calculates an obesity index corresponding to the abdomen width using a first equation if the obesity evaluator evaluates that the obesity degree is low, and calculates an obesity index corresponding to the abdomen width and the shape index using a second equation different from the first equation if the obesity evaluator evaluates that the obesity degree is high.

  • Publication number: 20130226010
    Abstract: A blood pressure measurement apparatus includes a blood pressure measurement unit, a bio-information acquisition unit, a depth calculation unit, a storage unit and a decision unit. The bio-information acquisition unit continuously acquires bio-information of a subject. The depth calculation unit repeatedly calculates depth indices each indicating a sleep stage of the subject on the basis of the acquired bio-information. The storage unit stores the calculated depth indices. The decision unit decides whether the sleep stage of the subject in sleep satisfies a starting condition, on the basis of a first depth index stored in the storage unit and a second depth index calculated by the depth calculation unit. The blood pressure measurement unit measures blood pressure data of the subject when the sleep stage is decided to satisfy the starting condition.

  • Patent number: 8409115
    Abstract: A CPU (134) of a body composition measuring apparatus (100) drives a navel position indicator (118) so that it emits light. The height of a frame (114) is adjusted so that a beam of light from navel position indicator (118) irradiates the navel of a human subject. Plural sensors (106) are mounted on the frame (114), and each sensor measures a distance from the sensor to a position to be measured, whereby the abdominal width (X) of the human subject is determined. Subsequently, CPU (134) obtains measured values of weight (W) and bioelectrical impedance (Z). CPU (134) then reads an equation for calculating the visceral fat area and estimates the visceral fat area (Y) based on the measured abdominal width (X), weight (W), bioelectrical impedance (Z), and the equation.
