Abstract: A biometric measurement apparatus has a measurement unit for measuring bioelectric impedance of different parts of a body and hematocrit. The measurement unit has impedance calculators (IPG1, IPG2) for measuring the impedance of tissues and blood of a living body with a first frequency to output as a first impedance (Z1), and for measuring the impedance of the tissues and blood of the living body with a second frequency to output as a second impedance (Z2), and has pulse wave analyzing units (MS1 and MS2) for analyzing differences of the first impedance between a first time and a second time and difference (?ZH) of the second impedance between the first time and the second time, and a hematocrit calculator (245) for calculating hematocrit based on the difference (?ZL) of the first impedance and the difference (?ZH) of the second impedance.
Abstract: A measuring apparatus for capacitor is applied to a charging power source and a capacitor to be measured. The measuring apparatus for capacitor includes a microcontroller unit, an analog-digital converter unit, a charging-side switch unit, a charging-side resistor unit, a discharging-side switch unit and a discharging-side resistor unit. The capacitor to be measured is charged and discharged by the charging-side switch unit and the discharging-side switch unit controlled by the microcontroller unit. The charging and discharging voltage and time variation of the capacitor to be measured are measured by the analog-digital converter unit to calculate the capacitance value of the capacitor to be measured.
