Publication number: 20140270210Abstract: A hearing prosthesis fitting system includes a first interface configured for applying a stimulation signal to a recipient of the hearing prosthesis. Generally, the stimulation signal is associated with a prior probability that the recipient will perceive the stimulation signal as an audible sound. The fitting system also includes a second interface configured for receiving response data relating to whether the recipient perceived the stimulation signal as an audible sound. Further, the fitting system includes a processor configured to determine an updated probability that the recipient perceived the stimulation signal as an audible sound. More particularly, the processor is configured to utilize the received response data and the prior probability to determine the updated probability.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Inventor: Bastiaan van Dijk

Patent number: 8571675Abstract: The measurement of recipient-specific operating parameters for each of a plurality of stimulation channels of a stimulating medical device. Generally, a recipient-specific operating parameter is measured for selected stimulation channels. These measured values are then used to estimate the same operating parameter for the remaining stimulation channels. For each such remaining stimulation channel, the accuracy of the estimated operating parameter value is determined, resulting in the estimated operating parameter value being deemed either valid or invalid. The validated values are retained while in invalidated values are replaced with a directly-measured or re-estimated operating parameter value.Type: GrantFiled: April 20, 2007Date of Patent: October 29, 2013Assignee: Cochlear LimitedInventor: Bastiaan van Dijk

Patent number: 8285382Abstract: 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.Type: GrantFiled: June 13, 2006Date of Patent: October 9, 2012Assignee: Cochlear LimitedInventors: Bastiaan van Dijk, Matthijs Killian, Andreas Buechner, Joerg Pesch, Marc Majoral, John L.

Publication number: 20120197065Abstract: The present application discloses systems and methods for displaying and operating a user interface having one or more channel group controllers corresponding to one or more groups of hearing prosthesis channels. The hearing prosthesis may be configured to generate a plurality of signals via a plurality of channels based on a channel profile. The channel profile may define at least one intensity level for each channel. In operation, the user interface may be configured to instruct the hearing prosthesis to change the channel profile of the plurality of channels in response to receiving an input via one of the channel group controllers. The user interface may be used to fit a hearing prosthesis to a recipient. In one embodiment, an initial channel profile may be automatically determined, and the prosthesis channel profile may be adjusted by changing a representative intensity level corresponding to the channel profile.Type: ApplicationFiled: January 28, 2011Publication date: August 2, 2012Applicant: Cochlear LimitedInventors: Andrew Botros, Bastiaan van Dijk, Rami Banna
