Patent number: 9084892Abstract: 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.Type: GrantFiled: June 15, 2006Date of Patent: July 21, 2015Assignee: Cochlear LimitedInventors: Peter J. Blamey, Brett A. Swanson, Hugh McDermott, James F. Patrick, Graeme M. Clark

Patent number: 8260429Abstract: In one aspect of the invention, a cochlear implant constructed and arranged to successively generate stimulation signals each comprising at least one stimulus pulse such that said successive stimulation signals incrementally build a neural excitation pattern that accurately reflects a received sound. In one embodiment, each said successive stimulation signal is generated based on the cumulative effect of all previous stimulus pulses, thereby compensating for finite spatial spreading of individual stimulus pulses as well as for the temporal integration of the neural excitation pattern along the neural pathways.Type: GrantFiled: January 11, 2008Date of Patent: September 4, 2012Assignees: The University of Melbourne, Bionic Ear Institute, Cochlear LimitedInventors: Peter J. Blamey, Bonar Dickson, Brett A. Swanson

Patent number: 8135152Abstract: 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.Type: GrantFiled: February 23, 2009Date of Patent: March 13, 2012Assignees: Cochlear Limited, The University of MelbourneInventors: Brett A. Swanson, Peter J. Blamey, Hugh J. McDermott, James F. Patrick

Patent number: 6068652Abstract: There is provided a system for predicting the characteristic frequency of each electrode of an implanted cochlear electrode array from electrode position data contained in an image of the implanted cochlea. There is also provided a system for setting the frequency range to electrode map of a cochlear prosthesis.Type: GrantFiled: March 10, 1998Date of Patent: May 30, 2000Inventors: Lawrence T.

Patent number: 5271397Abstract: An improved pulsatile system for a cochlear prosthesis is disclosed. The system employs a multi-spectral peak coding strategy to extract a number, for example five, of spectral peaks from an incoming acoustic signal received by a microphone. It encodes this information into sequential pulses that are sent to selected electrodes of a cochlear implant. The first formant (F1) spectral peak (280-1000 Hz) and the second formant (F2) spectral peak (800-4000 Hz) are encoded and presented to apical and basal electrodes, respectively. F1 and F2 electrode selection follows the tonotopic organization of the cochlea. High-frequency spectral information is sent to more basal electrodes and low-frequency spectral information is sent to more apical electrodes. Spectral energy in the regions of 2000-2800 Hz, 2800-4000 Hz, and above 4000 Hz is encoded and presented to three fixed electrodes.Type: GrantFiled: December 16, 1991Date of Patent: December 21, 1993Assignees: Cochlear Pty. Ltd., The Univ. of MelbourneInventors: Peter M. Seligman, Richard C. Dowell, Peter J. Blamey

Patent number: 4982432Abstract: An electrotactile vocoder for persons having impaired hearing in which electrical stimulation is applied to a multiplicity of electrodes in contact with either side of each finger so as to electrically stimulate the digital nerves of the user under the control of stimulator circuitry which is in turn controlled by processing circuitry for a speech signal received by a directional microphone worn on the ear of the user. The speech processor is suitably of the type described in U.S. Pat. No. 4,441,202 Tong et al. modified to cause stimulation of the digital nerves via the eight finger electrodes and a common electrode held in contact with the wrist of the user.Type: GrantFiled: November 29, 1989Date of Patent: January 1, 1991Assignee: University of MelbourneInventors: Graeme M.
