  • Publication number: 20220141601
    Abstract: A method for picking up body signals from the head of a user comprises a) placing first and second electrodes on first and second different positions at a first side of the user's head in direct or capacitive contact with the user's head, said first side comprising a first eye of the user, the first and second electrodes being configured to pick up first and second electric potentials, respectively, from the user's body, and b) providing an Electrooculography signal representative of a corneo-retinal potential difference of said first eye of the user in dependence of said at first and second electric potentials. The first and second positions may be (substantially) located in a plane including the first eye of the user. A portable electronic device providing an Electrooculography signal, and a hearing device utilizing an Electrooculography signal is further disclosed.

  • Publication number: 20180368722
    Abstract: An electrooculography (EOG) signal capture system comprises a) a sensor array adapted for being located at one of a left or right ears of a user and/or for fully or partially being implanted in the head at left or right ears of a user, the sensor array comprising a number Ns of electric potential sensors, respectively, for sensing respective electric potentials from the user's head, where Ns is larger than or equal to two, b) electronic circuitry coupled to the sensor array and configured to provide at least two different beamformed signals (SBF1, SBF2), each being representative of a weighted combination of said electric potentials, or of signals derived therefrom, and wherein a difference between said at least two different beamformed signals (?PBF=SBF1?SBF2)—at least in a specific electrooculography mode of operation—represents an electrooculography signal (?PEOG) from one or both eyes of said user. A single-sensor EOG-system is further proposed. The invention may e.g.

  • Patent number: 9630008
    Abstract: Disclosed herein are embodiments of methods and systems for attenuating artifacts in single channel cochlear implants. Both high and low frequency artifacts can be attenuating using embodiments of the disclosed methods and systems. In some embodiments, low-pass filters, impedance balancing, and DC artifact estimation can be used, alone or in combination, to attenuate or completely remove artifacts in single channel cochlear implants.
