  • Patent number: 9084892
    Abstract: The sound processor and method uses a model of basilar membrane motion to select stimuli, based upon the predicted motion which the acoustic signal presented would produce in an acoustically excited normally hearing cochlea. The filter; used, in contrast to single channel per electrode approaches, cover multiple channels and overlap with each other. Consequently the stimuli presented produce a neural excitation pattern which approximates the spatio-temporal travelling wave observed on the basilar membrane in an acoustically excited normally hearing cochlea. Preferably, the predicted electrode stimuli are based upon the instantaneous predicted amplitude of the electrode location.

  • Patent number: 8644944
    Abstract: An implantable stimulation device is disclosed which provides for reduced power consumption when compared with bipolar stimulation and better stimulation performance when compared with monopolar stimulation. Implantable stimulator devices use less power in monopolar stimulation mode than that of bipolar stimulation but stimulation performance is greater when using bipolar stimulation. The device comprises circuitry capable of simultaneous stimulation between a reference electrode and an electrode of a stimulation array and between electrodes of the stimulation array, the ratio of current to the reference electrode and array electrodes being selectable.

  • Patent number: 8285382
    Abstract: An embodiment of the present invention takes masking effects into consideration when determining stimulation signals for neural stimulation. These masking effects may be modeled using user-specific models determined by taking measurements for an implant system of an implant recipient. Or, the model may correspond to a group of individuals sharing a common characteristic or the population as a whole. These models may be, for example, psycho-physical models.

  • Patent number: 8135152
    Abstract: A method and apparatus for detecting an envelope of an audio signal, and a method and apparatus for enhancing the pitch cue of an audio signal perceived by a cochlear implant patient where the audio signal is processed and input to an implant device of the recipient. The methods and apparatuses use techniques such as filtering, rectifying, detecting peak values, sampling, resetting, comparing and multiplying various signals to detect the envelope or enhance the pitch cue of the audio signal.
