    • An acquisition device for electrical impedance analysis for determining body composition parameters includes a control and analysis unit including measuring and processing circuitry and at least two electric lines, each of which lines is connected to the control and analysis unit and has an electrode. Each electrode is dedicated for connection at an assigned measuring position out of a set of predetermined measuring positions. The control and analysis unit is arranged to cause application of alternating current through electrodes and to measure a resulting voltage between electrodes; record a time dependent electric signal generated by cardiac activity of the subject for each pair of electrodes; and by comparing the time dependent electric signals with expected electric signals of cardiac activity for the predetermined measuring positions, assign to the electrodes those measuring positions for which the time dependent electric signals best fit the expected electric signal of the cardiac activity.
    • 用于确定身体组成参数的用于电阻抗分析的采集装置包括控制和分析单元,其包括测量和处理电路以及至少两条电线,每条线与控制和分析单元连接并具有电极。 每个电极专用于在一组预定测量位置之间在分配的测量位置连接。 控制和分析单元被布置成使得通过电极施加交流电流并测量电极之间的所得电压; 记录由每对电极对象的心脏活动产生的与时间相关的电信号; 并且通过将时间相关电信号与预定测量位置的心脏活动预期电信号相比较,将与时间相关的电信号最适合于心脏活动的预期电信号的那些测量位置分配给电极。
