Abstract: A wearable EEG monitor for continuously monitoring the EEG of a user through capacitive coupling to an ear canal of a user comprises an ear insert (1) for positioning within the human ear canal, comprising at least two capacitive electrodes (16) for recording a signal. The electrodes are coated with a dielectricum for electrical insulation. The electrodes are connected to an amplifier (17). The amplifier has an input impedance matched to the impedance of the electrodes. The invention further provides a method of monitoring brain waves.

Abstract: In a monitoring device consisting of a reader and a data carrier, the reader (100) comprises a control unit (101), a memory (102), a digital signal generator (103), an output driver (104), resonance capacitors (105, 107) and a transmitter coil (106). The digital signal generator (103) is adapted for supplying a digital bit sequence selected among, at least two, bit sequences stored in the memory (102) whereby the strength of the magnetic field generated by the transmitter coil (106) can be varied dependent on the bit sequence selected by the control unit (101). The invention further provides a method of controlling the strength of a magnetic field generated by the reader of the monitoring device.

Abstract: A personal wearable EEG monitor comprising an implantable electrode part with at least two electrodes (2,3) for measuring an EEG signal of a person. The electrode part comprises an electronic circuit arranged in a housing (1) with each electrode arranged external to the housing. The electrode part comprises a testing circuit for testing functionality of the electrode part. The testing circuit comprises a capacitor (9) coupled in serial connection to at least one of the electrodes, and a test signal generator for providing a test signal. The EEG monitor is adapted for analyzing the signal resulting from the signal generator for identification of faults in the electrode part. The invention further provides a method for detecting a leak current in an implanted EEG monitor part.

Abstract: A hearing aid comprising a wireless transceiver (100) having an inductive antenna (101) and a trimming capacitor (104, 105, 300, 404) with at least two parallel signal paths, wherein at least one of said signal paths comprises a first capacitor (309, 310, 311, 312), a second capacitor (301, 302, 303, 304) and a switching transistor (305, 306, 307, 308) arranged such that the switching transistor (305, 306, 307, 308) is coupled in parallel with said first capacitor (309, 310, 311, 312) and coupled in series with said second capacitor (301, 302, 303, 304), whereby the voltage drop across the switching transistor (305, 306, 307, 308), when the switching transistor is set to off, will be lower than the voltage applied across the trimming capacitor (104, 105, 300, 404) due to voltage division between said first capacitor (309, 310, 311, 312) and said second capacitor (301, 302, 303, 304). The invention also provides a method of fitting a wireless transceiver (100) for a hearing aid.
