Abstract: Proximity of a person causes a change in a capacitance value of a sensor capacitor having a pair of capacitive plates. The change is detected by charging the sensor capacitor by coupling the sensor to a voltage supply. The supply is disconnected from a tank capacitor during the charging. The charge is transferred from the sensor capacitor to a tank capacitor. The supply is disconnected from the tank capacitor during the charge transfer. The charging and charge transfer are repeated several times. The voltage of the tank capacitor is monitored. At least one value is determined which depends on the rate of change of the voltage of the tank capacitor. The capacitance of the tank capacitor may be several orders of magnitude higher than the capacitance of the sensor capacitor. The large tank capacitor acts as a part of a low-pass filter which effectively filters out signal noise.

Abstract: The invention relates to a method and apparatus for detecting artifacts in a bioelectric signal, especially in a frontal EEG signal. In order to accomplish an uncomplicated mechanism for detecting artifacts in clinical applications, an impedance signal is measured through a first electrode set attached to the skin surface in a measurement area of a patient's body, the impedance signal being indicative of the impedance of the signal path formed between individual electrodes of the set. Simultaneously with the impedance measurement, a bioelectric signal is acquired through a second electrode set also attached to the skin surface of the measurement area, and the time periods are determined during which the impedance signal fulfills at least one predetermined criterion indicative of the presence of artifact in the bioelectric signal. In one embodiment, the first and second electrode sets are formed by a common set of two electrodes.
