    • A method for detecting the presence, and/or determining the location, and/or detecting changes in the material properties, of a first object (4) within a predefined space (12) and compensating for the disturbance caused by a second object, where the method comprises the following steps: providing at least a first and a second electrode (6) capacitively coupled to each other; conductively applying an electrical signal to each of the first and second electrodes (6), the electrical signals being different for the first and second electrodes (6); for each of the electrodes (6) measuring the current signal through, and/or the voltage signal on, the electrode (6); deriving from the measured values an indication of the disturbance caused by the second object; and deriving from the measured values and the indication of the disturbance a disturbance-compensated indication of the presence, and/or the location, and/or changes in the material properties, of the first object (4).
    • 一种用于检测在预定空间(12)内的第一对象(4)的存在和/或确定位置和/或检测材料属性的变化并补偿由第二对象引起的干扰的方法,其中 该方法包括以下步骤:提供至少彼此电容耦合的第一和第二电极(6); 对第一和​​第二电极(6)中的每一个导电地施加电信号,对于第一和第二电极(6),电信号不同。 对于测量电流信号的每个电极(6)和/或电极(6)上的电压信号; 从测量值得出由第二物体引起的干扰的指示; 并且从第一物体(4)的测量值和干扰指示导出干扰补偿的存在和/或位置指示和/或材料特性的改变。
