Body-region separately weighing system and methods

A body-region separately weighing system which weighs each of six body regions of the head, trunk, right arm, left arm, right leg and left leg of a human body, comprising:

• six body-region measuring units each provided for each of the six body regions and including a supporter supporting each body region, a weighing portion right below the supporter weighing each body region on the supporter by being sent a load borne on the body-region supporter and a data transmitting-receiving portion transmitting and receiving data including body-region weight data measured by the weighing portion;
• and
• a data processing unit transmitting control data for weighing each body region and receiving the measured body-region weight data to and from each of the six body-region measuring units,
• wherein the data processing unit includes a means for determining each body region's weight by using the weight of a whole bod (BW) measured at an earlier stage and the measured body-region weight data, which comprises:
• a first means for acquiring a plurality of measured values (xi) and calculating an average value (Xave) and a fluctuation width (Δxi) therefor for each body region;
• a second means for deciding whether the fluctuation width (Δxi) is within a first predetermined tolerance (δa);
• a third means for temporarily setting the average value (Xave) as each body region's weight and storing it in the storage unit when the fluctuation width (Δxi) is within the first predetermined tolerance (δa);
• a fourth means for calculating the total weight (Xt) of the temporarily set weights of the plurality of body regions;
• a fifth means for deciding whether a difference between the total weight (Xt) and the weight of the whole body (BW) is within a second predetermined tolerance (δb);
• and
• a sixth means for defining each of the average values (Xave) as each body region's weight and storing it in the storage unit when the difference is within the second predetermined tolerance (δb).
