METHODS AND SYSTEMS FOR DETECTING THE PRESENCE, OR DETERMINING THE LOCATION OR THE SIZE, OR DETECTING CHANGES OF MATERIAL PROPERTIES, OF AN OBJECT WITHIN A PREDEFINED SPACE |
摘要 |
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). |
