    摘要: An electroimpedance tomograph with a plurality of electrodes (1) is provided, which can be placed on the body of a patient and are connected via a selector switch (60) with a control and evaluating unit (20). The control and evaluating unit (20) cooperates with the selector switch (60) such that two electrodes each are supplied with an alternating current from an AC power source (22) and the detected analog voltage signals of the other electrodes are processed in order to reconstruct therefrom the impedance distribution of the body in the plane of the electrodes, wherein a symmetrical AC power source is used to reduce common-mode signals. To further suppress interferences due to common-mode signals, provisions are made for the control and evaluating unit (20) to be set up, furthermore, for detuning the common-mode signal of the alternating current on the body against the ground by means of a common-mode signal measuring electrode (4) and, based on this, the symmetry of the symmetrical AC power source such that the common-mode signal on the body is minimized, and the corresponding detuning parameters are stored for each electrode pair.

    摘要: A radio frequency detection system is provided that includes at least two radio frequency detection devices, which have an antenna each with a detection range for a radio frequency identification and detect the radio frequency identification information provided in the detection range. The radio frequency detection system is designed to attenuate a detection range of a detecting radio frequency detection device in the detection range of the at least one other radio frequency detection device by means of a compensation member such that the radio frequency identification cannot be detected by the detecting radio frequency detection device in the detection area of the at least one other radio frequency detection device. The compensation member feeds a compensation current to the at least one other antenna to generate an opposing magnetic field, which attenuates or extinguishes the magnetic field of the detecting antenna in the at least one other detection range, by the at least one other antenna in the at least one other detection range.
