  • Patent number: 10741373
    Abstract: The invention relates to a method for operating an ion gate having a first, a second, and a third electrode which are arranged one after the other in an intended drifting direction of ions to be influenced by the ion gate, in such a way that the second electrode is arranged after the first electrode and the third electrode is arranged after the second electrode in the drift direction. The ion gate can be switched between a closed state, in which ions cannot drift through the ion gate in the intended drifting direction, and an open state, in which ions can drift through the ion gate in the intended drifting direction. This is accomplished by applying potentials that alternate over time to one or more of the electrodes. In a switching cycle of the ion gate, which comprises the open state and the closed state of the ion gate, two different closed states of the ion gate are produced. In a first closed state, the ion gate is closed by applying a first potential between the second and third electrodes.

  • Patent number: 10668272
    Abstract: A cochlear implant of a cochlear implant system is described. The cochlear implant comprises electrodes which are mechanically connected to one another and can be inserted in a row in the form of a spiral into a cochlea in order for auditory nerve receptors to be stimulated, a control circuit that can specifically apply electric pulses to the individual electrodes, and an energy source. The control circuit allows the electrodes to be fed in a pulsed manner with electric signals generated by a processor from the acoustic signals, and auditory nerve receptors adjacent to the electrodes to be stimulated. The electrodes are components of modules, each of which comprises its own decoder-and-control circuit for decoding module addresses and stimulation signals and generating electric pulses for the electrodes. Encoded module addresses and stimulation signals generated from acoustic signals are applied to inputs of the decoder-and-control circuit.
