    摘要： A personal wearable EEG monitor with a base part (1) having signal processing means (23),an electrode part (2) with at least two electrodes (11, 12) for measuring an EEG signal of a person. The electrode part(2)comprises means for converting the EEG signal into a digital signal. The EEG monitor comprises a databus for transferring data between the base part (1) and the electrode part (2) and for providing power from one part to the other. The databus is adapted for application of two electrical wires.

    摘要： A system for remote surveillance of an EEG signal of a person susceptible of having a hypoglycemic seizure comprises an EEG sensor part with electrodes for measuring one or more EEG signals from the person, and a processing unit adapted to be arranged at the ear of said person. EEG signal processing means is adapted for analyzing the EEG signal, for identifying or predicting a hypoglycemic seizure in the person. The system comprises a first connection between the EEG sensor part and the processing unit, adapted for transmitting an EEG signal from the implantable EEG sensor to the processing unit. The system comprises an external part adapted to receive wirelessly an alarm from the processing part, where the external part is adapted to forward an alarm to a care-giver. The invention further provides a method of EEG surveillance.

    摘要： An active electrode has an electrode for sensing an electric potential and generating an input signal, and a shield placed near the electrode but being electric insulated from the electrode. An integrated amplifier (10) has an input connected to the at least one electrode for receiving the input signal, and providing a buffered path outputting a buffered output signal. The shield being connected to the output of the integrated amplifier to actively drive the electrical potential of the shield, thereby providing an active shielding of the electrode. The buffered path includes a first mixer (11) in front of the integrated amplifier for frequency shifting the input signal from a basic frequency range to a higher frequency range, and a second mixer (12) on the output of the integrated amplifier for frequency shifting the amplified signal from the higher frequency range back to the basic frequency range. The active electrode may be used for recording EEG signals.

    摘要： A portable monitoring device comprises a hearing aid having a housing, a microphone (24), an acoustic signal processing means (43), and an acoustic output transducer (33). The portable monitoring device further comprises an EEG monitoring system arranged at least partly in said housing, and comprising a measuring unit (3) having electrodes (12) arranged external to the housing. The EEG monitoring system comprises a processing unit (42) for analyzing the EEG signal for identifying or predicting specific biological incidences, such as a seizure, in said person, decision means for deciding, based on said analyzed EEG signal, when an alarm or information must be provided to said person, and means for providing said alarm or information through said output transducer (33). The invention further provides a method of monitoring an EEG signal of a hearing impaired person.
