摘要： 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.

摘要： A method and system for analyzing the status of a subject. A cordless recording device comprising a set of electrodes is attached on the forehead of the subject to collect brain wave signal data from the subject. Based on the brain wave signal data, status information indicative of the status of the subject during a measurement period is generated. A bioimpedance signal is further measured through two electrodes of the electrode set and heart rate data is derived from the bioimpedance signal. The heart rate data is utilized to enhance the quality of the status information, which is typically sleep state information. The invention also relates to a recording device attachable to the forehead of the subject. The recording may comprise a data memory for storing the data measured from the subject during the measurement period.
