  • Publication number: 20150163605
    Abstract: A system and method are described for generating electrode stimulation signals for electrode contacts in a cochlear implant electrode array. An input audio signal is processed to generate band pass channel signals that each represent an associated band of audio frequencies. From each channel signal channel, audio information is extracted including a channel signal envelope reflecting channel signal energy. Initial electrode stimulation pulses are then generated based on the band pass signal envelopes. A gating function is applied to the initial electrode stimulation pulses based on a gating feedback signal characterizing preceding stimulation signals to produce gated electrode stimulation pulses. The gated electrode stimulation pulses are set to the initial electrode stimulation signals when the band pass signal envelopes are greater than the gating feedback signal, and otherwise are set to zero.

  • Publication number: 20150080980
    Abstract: A signal processing arrangement generates electrode stimulation signals to stimulation contacts in a cochlear implant electrode array. A signal filter bank transforms an input sound signal into band pass signals, which each represent an associated frequency band of audio frequencies. An envelope processing module processes the band pass signals in a sequence of sampling time frames, wherein for each time frame, the processing includes calculating for each band pass signal at least one signal envelope dynamic property that is changing during the time frame. A channel selection module selects one or more of the band pass signals for each time frame based on the dynamic properties to produce the electrode stimulation signals to the stimulation contacts.

  • Patent number: 8948877
    Abstract: A system and method for activating stimulation electrodes in cochlear implant electrode is described. A preprocessor filter bank is configured to process an input acoustic audio signal to generate band pass signals that each represent an associated band of audio frequencies. An information extractor is configured to extract stimulation signal information from the band pass signals based on assigning the band pass signals to corresponding electrode stimulation groups that each contain one or more stimulation electrodes, and generates a set of stimulation event signals for each electrode stimulation group that define electrode stimulation timings and amplitudes. A pulse selector is configured to select a set of electrode stimulation signals from the stimulation event signals based on a pulse weighting function that uses channel-specific weighting factors favoring lower frequencies for activating the stimulation electrodes to stimulate neighboring audio nerve tissue.

  • Patent number: 8868195
    Abstract: A method of generating electrode stimulation signals for an implanted electrode array is described. An acoustic audio signal is processed to generate band pass signals which each represent an associated band of audio frequencies. For each band pass signal, fine time structure information is extracted to determine a sequence of phase event signals. For each sequence of phase event signals, when the number of phase event signals reaches a channel pitch rate factor, a signal limiting period without signals is introduced to produce a modified sequence of phase event signals. Each modified sequence of phase event signals is weighted with a channel amplitude value in order to generate a set of electrode stimulation signals for the implanted electrode array.

  • Patent number: 8489194
    Abstract: A system and method of signal processing for a hearing implant. The hearing implant includes at least one electrode, each electrode associated with a channel specific sampling sequence. An acoustic audio signal is processed to generate for each electrode a band pass signal representing an associated band of audio frequency. For each electrode, a sequence signal is determined as a function of the electrode's associated band pass signal and channel specific sampling sequence. An envelope of each band pass signal is determined. The envelope of each band pass signal is filtered to reduce modulations resulting from unresolved harmonics, creating for each electrode an associated filtered envelope signal. Each electrode's sequence signal is weighted based, at least in part, on the electrode's associated filtered envelope signal.

  • Patent number: 8428743
    Abstract: A method is described for generating electrode stimulation signals for an implanted electrode array. An acoustic audio signal is processed to generate band pass signals each representing an associated band of audio frequencies. Stimulation information is extracted from the band pass signals to generate stimulation event signals defining electrode stimulation signals. The stimulation event signals are mapped according to independent channel-specific loudness functions to produce a set of electrode stimulation signals within channel-specific minimum and maximum threshold levels. The electrode stimulation signals are developed into a set of output electrode pulses to the electrodes in the implanted electrode array.

  • Patent number: 8374699
    Abstract: An implantable stimulation arrangement is described for generating electrode stimulation signals for an implanted electrode array having stimulation electrodes. A filter bank pre-processor processes an input acoustic audio signal to generate band pass signals each corresponding to an associated band of audio frequencies. A signal envelope module computes a corresponding signal envelope for each band pass signal. A stimulation pulse generator extracts stimulation signal information from the rate of change of the signal envelopes such as a time-based derivative to generate stimulation event signals defining electrode stimulation timings and amplitudes for some or all of the stimulation electrodes.

  • Patent number: 7912605
    Abstract: A method for triggering a reversible occupant safety function in a motor vehicle, in which the value of a triggering parameter is determined, the value of the triggering parameter is compared with a predetermined threshold value, and the occupant protection function is triggered when the predetermined threshold value is exceeded by the value of the triggering parameter. An aspect of the method is that the threshold value is influenced by a driving style parameter determined by analysis of the brake and/or gas pedal operating procedures and/or by an operating element operable by the driver.
