Abstract: An autonomous distribution board receives feeding of power via a distribution board for a period during which grid power is supplied from a grid power source, while receiving power via an autonomous terminal of a power conversion apparatus for a period during which supplying of grid power from grid power source is stopped. Autonomous distribution board is connected with a specific load and the like. A measurement point switching apparatus is configured to select one from a current sensor configured to monitor a current that flows through a main breaker, and a current sensor configured to monitor a current that is supplied from power conversion apparatus to autonomous distribution board. A fuel battery is configured to adjust an output thereof based on an output of the selected one so that power by fuel battery is consumed by a general load, specific load and the like.

Abstract: A body fat measuring device comprises electrodes brought into contact with the waist portion of a subject, an optical sensor composed of a light applying section and a light receiving section, an impedance computing section for computing the impedance between the electrodes, a subcutaneous fat thickness computing section for computing the thickness of the subcutaneous fat of the subject from the value detected by the optical sensor, and a body fat computing section which subtracts the amount of subcutaneous fat determined using the thickness of the subcutaneous fat computed by the subcutaneous thickness computing section from the total fat amount of the subject determined using the impedance computed by the impedance computing section so as to determine the visceral fat amount of the subject. With this, not only the accuracy of measurement of the visceral fat amount is improved but also the visceral fat amount of the subject can be easily computed even without a database.
