  • A hearing aid system comprising EEG electrodes.
  • 2013
  • Patentabstract
    • The invention relates to a hearing aid system for obtaining an ambulatory electroencephalogram, EEG, comprising two or more electric terminals in the surface of a hearing instrument shell where it contacts the skin inside or outside the ear canal. The electrical terminals may all serve the same purpose (e.g. measuring EEG) or different purposes (e.g. three for measuring EEG and one for measuring body temperature).

  • Automatic Real-Time Hearing Aid Fitting Based on Auditory Evoked Potentials.
  • 2013
  • Patentabstract
    • A hearing aid includes at least one electrode located at a surface of a housing of the hearing aid to allow the electrodes to contact the skin of a user during use of the hearing aid, at least one electrode being adapted to pick up a low voltage signal from the user's brain, an amplifier unit operationally connected to the electrode(s) and adapted for amplifying the low voltage signal(s) to provide amplified brain signal(s), and a signal processing unit adapted to process the amplified brain signal(s) to provide a processed brain signal as well as to apply a time and frequency dependent gain to an input audio signal and to provide a processed audio output signal. Also a method of operating a hearing aid and a hearing aid system.

  • Hearing device with brain-wave dependent audio processing.
  • 2013
  • Patentabstract
    • Hearing device (1) adapted to be worn by an individual and comprising: a housing (2) arranged at an ear; an input means (3, 4, 5, 6) providing one or more input audio signals; a signal processing circuit (7, 8) processing at least one of said one or more input audio signals to provide a processed audio signal; an output transducer (10) providingt an audible signal to the individual in dependence on the processed audio signal; two or more electrodes (13, 14, 20) detecting electric brain potentials of the individual; and a brain-wave measurement circuit (15, 21, 25) determining one or more EEG signals from electric signals received from the two or more electrodes (13, 14, 20), wherein the hearing device (1) further comprises: a first spectrum analyser (11, 12) adapted to repeatedly determine first audio spectra of at least one signal from the group of signals consisting of said one or more audio input signals and the audible signal; a reconstructor (16) adapted to repeatedly reconstruct second audio spectra from the one or more EEG signals; a first correlator (17, 18) adapted to repeatedly determine a first coherence between the first and the second audio spectra; and a control unit (19) adapted to alter said processing in dependence on the first coherence.

  • Method of operating a hearing instrument based on an estimation of present cognitive load of a user and a hearing aid system.
  • 2013
  • Patentabstract
    • The invention relates to a method of operating a hearing instrument for processing an input sound and to provide an output stimulus according to a user's particular needs. The invention further relates to a system, a computer readable medium and a data processing system. The object of the present invention is to provide an improved customization of a hearing instrument. The problem is solved in that the method comprises the steps a) providing an estimate of the present cognitive load of the user; b) providing processing of an input signal originating from the input sound according to a user's particular needs; and c) adapting the processing in dependence of the estimate the present cognitive load of the user. This has the advantage that the functionality of the hearing aid system is adapted to the current mental state of the user. The estimate of the present cognitive load of a user is produced by in-situ direct measures of cognitive load (e.g. based on EEG-measurements, body temperature, etc.) or by an on-line cognitive model in the hearing aid system whose parameters have been preferably adjusted to fit to the individual user. An estimate of a user's cognitive status or cognitive load can e.g. be based on an estimate of the user's working memory capacity. The invention may e.g. be used in applications where a hearing impaired user's current mental resources are challenged.

  • N band FM demodulation to aid cochlear hearing impaired persons.
  • 2013
  • Patentabstract
    • The invention relates to: A signal processing device comprising a signal processing unit for processing an electrical SPU-input signal comprising frequencies in the audible frequency range between a minimum frequency and a maximum frequency, and providing a processed SPU output signal. The invention further relates to its use and to a method of operating an audio processing device. The object of the present invention is to provide a scheme for improving a user's perception of an acoustic signal. The problem is solved in that an FM to AM transformation unit for transforming an FM2AM input signal originating from the SPU-input signal and comprising at least a part of the frequency range of the SPU-input signal from a frequency modulated signal to an amplitude modulated signal to provide an FM2AM output signal, which is used in the generation of the processed SPU output signal. This has the advantage of providing an improved perception by a hearing impaired user of an input sound.

  • System and Method for Eliminating Feedback and Noise In a Hearing Device.
  • 2009
  • Patentabstract
    • This invention relates to a system (100) and method for synthesizing an audio input signal of a hearing device. The system (100) comprises a microphone unit (102) for converting the audio input signal to an electric signal, a filter unit (110) for removing a selected frequency band of the electric signal and pass a filtered signal, a synthesizer unit (118) for synthesizing the selected frequency band of the electric signal based on the filtered signal thereby generating a synthesized signal, a combiner unit (120) for combining the filtered signal and the synthesized signal so as to generate a combined signal, and finally an output unit (122, 124, 126) for converting the combined signal to an audio output signal.

  • System for acquiring and processing data pertaining to a shot of an object, such as a puck or a ball, on a goal ona playing field.
  • 2012
  • Patentabstract
    • According to the present inventive concept there is provided a system for acquiring and processing data pertaining to a shot of an object, such as a puck or a ball, on a goal on a playing field, the goal being guarded by a goalkeeper, the system comprising: an acquisition device configured to acquire position data of the object during a time interval ΔTP preceding the shot on goal, and a processing device configured to process the acquired position data of the object to estimate if an unobstructed path between the goalkeeper and the object is maintained throughout said time interval ΔTP, and configured to register the shot on goal as a first type of shot at least on a condition that an unobstructed path between the goalkeeper and the object not was maintained throughout said time interval ΔTP.
