  • Patent number: 9717901
    Abstract: A cochlear implant includes electrodes and a processor for generating frequency-modulated electrical pulse trains in one or more of the electrodes responsive to dividing data representing audio spanning frequency-bands into bins associated with each frequency-band, each bin representing an energy level of the data within the frequency-band within a time-period; associating each frequency-band with a phase probability that starts at an initial phase probability value (PPV), resets to a minimum PPV after generating a pulse, and increases from the minimum PPV to a maximum PPV over a time-period; for each bin, assigning a power probability as a normalized intensity being a number between a minimum power probability and a maximum power probability representing the energy level of the bin, and generating a pulse in an electrode associated with the frequency-band associated with the bin when a random number generated is less than the power probability divided by the phase probability.

  • Patent number: 9623242
    Abstract: A method of generating frequency-modulated pulse trains in a CI includes dividing data representing audio spanning frequency bands into a plurality of bins associated with each frequency band, each bin representing an energy level of the data within the frequency band within a period of time; associating each frequency band with a phase probability that starts at an initial phase probability value (PPV), resets to a minimum PPV after generating a pulse, and increases from the minimum PPV to a maximum PPV over a period of time; for each bin, assigning a power probability as a normalized intensity being a number between a minimum power probability and a maximum power probability representing the energy level of the bin, and generating a pulse in an electrode associated with the frequency band associated with the bin when a random number generated is less than the power probability divided by the phase probability.
