An exercise detection apparatus including: a load stage comprising a load surface onto which a load of parts or all of a human subject is applied; a load measurer for repeatedly or continuously measuring the load on the load surface; a calculator for calculating a difference between adjacent local maximum and minimum in the load varying over time measured by the load measurer repeatedly or continuously; and a detector for detecting a motion of the human subject when the difference calculated by the calculator is within a range.

Exercise detection apparatus

Disclosed is an improved living body variable measuring apparatus equipped with a display capable of presenting a time-related graphic representation. The graphic representation is composed of crosswise arrangement of rectangles relative to abscissa and ordinate representing time and measured quantity respectively. Each time-related column has a selected rectangle representing the quantity of a measured living body variable. The horizontal time-related arrangement of narrow rectangles facilitates survey of graphic representation. The living body variable measuring apparatus permits the user to select desired data among those measured for record, preventing so selected data from invading locations allotted to others' data and vice versa.

Bio-characteristic value measuring device with graphical display

Disclosed is a bioelectric impedance measuring apparatus which can prevent such abnormal condition than an excessive current is applied to a human body when elements in the circuit has failed or is damaged, with a simple circuit configuration and without decreasing the measuring accuracy of the bioelectric impedance. The bioelectric impedance measuring apparatus according to the present invention is configured such that a capacitor or a set of a capacitor and a resistor arranged in parallel with each other is installed between an electrode to be brought into contact with a human body and a bioelectric impedance measuring circuit section comprising a generating section for generating an alternating current applied to a human body for measurement, a measuring section for measuring a voltage value between the portions where the current is applied to the human body, a computing section for computing a bioelectric impedance value, and a central processing unit (CPU).
