  • SPEECH PROCESSOR CASES
    Publication number: 20120041517
    Abstract: Apparatus and methods for converting one type of speech processor unit into another type of speech processor unit.
    Type: Application
    Filed: October 18, 2011
    Publication date: February 16, 2012

  • Estimating flap thickness for cochlear implants
    Patent number: 7920924
    Abstract: A flap thickness measurement system includes a reference cochlear stimulation system. The reference cochlear stimulation system includes a sound processor, a transmitter that transmits a telemetric signal, and a cochlear stimulator having a receiver that receives the telemetric signal and transmits a signal back to the transmitter. The system further includes one or more flap simulators having one or more known thicknesses that is positioned between the transmitter and receiver. Also included is a microprocessor that receives and processes data representative of tank voltage from the reference cochlear stimulation system.

  • System and method for fitting a cochlear implant sound processor using alternative signals
    Patent number: 7496406
    Abstract: Alternative stimuli, i.e., stimuli other than the constant amplitude stimuli used in prior fitting schemes, is used to set the parameters of a cochlear implant system. The use of such alternative stimuli allows the entire fitting process to be completed in a very short time period, and generally eliminates the need for secondary adjustments. In one preferred embodiment, the alternative stimuli comprise white noise that is internally generated within the speech processor.

  • Encoding fine time structure in presence of substantial interaction across an electrode array
    Patent number: 7277760
    Abstract: A method for reducing the effects of decreased resolution in a cochlear implant worn by an individual includes 1) determining the value of the individual's resolution region, 2) analyzing a plurality of dominant components within a sound signal, 3) removing a component that has lesser associated energy of two or more components that are within the resolution region of one another, thereby producing a sound signal with a reduced pattern of components, and 4) transmitting the reduced pattern signal to an array of electrodes associated with the cochlear implant.
