Abstract:
1. A method to monitor localization, posture, movement or properties of one or several objects to be monitored in an environment to be monitored, wherein in the area of the environment to be monitored there is a transducer which is composed of a distribution of conductors, which are electrically insulated from the object and said distribution of conductors includes at least a first division of selectable conductors and a second division of selectable conductors, the method comprising the steps of a) selecting the conductors of the first division of conductors and conductors of the second division of conductors and connecting an excitation signal to the selected first division of conductors and performing a scanning cycle of the selected divisions of the selected conductors when the excitation signal is connected to the first division of the selected conductors; b) deriving a first signal from a coupling of the excitation signal between the first and the second selected divisions of conductors, and processing said first signal to obtain information about impedance of the object for characterization of the object.
