  • Patent number: 7813794
    Abstract: In a body fat measuring apparatus, a constant electric-current is flowed between hand electric-current electrodes and leg electric-current electrodes. From two detected voltages generated between an annular-shaped voltage electrode placed on an abdominal portion and two voltage electrodes placed at the both sides of a lumbar portion, two abdominal impedances are determined. Two electric-current electrodes and two voltage electrodes are placed such that they are spaced apart by a small interval from one another at an umbilicus portion. A constant electric current is flowed between the two electric-current electrodes and the impedance in the vicinity of the subcutaneous of the abdominal portion is determined from the detected voltage generated between the two voltage electrodes. From the two abdominal impedances, the impedance in the vicinity of the subcutaneous of the abdominal portion, and the input physique information, a viscera impedance is calculated.

  • Patent number: 6872182
    Abstract: Blood pressure measurement is precisely performed by more correctly determining positions of a cuff and a heart without being affected by variations in physical features among subject persons and their postures during the measurement. With the technique of the present invention, there are calculated the altitudes of the cuff and the heart on the basis of an inputted upper arm length and forearm length of a subject person and forearm angles detected in the pitch direction and roll direction. Also, in addition to a forearm angle detecting means, an upper arm angle detecting means is provided and the altitudes of the cuff and the heart are calculated on the basis of detected angles of a forearm and an upper arm. Also, a biaxial angle detecting means detects angles of the forearm in the pitch direction and the roll direction and calculates the altitudes of the cuff and the heart on the basis of these detected values.
