Patent number: 10449357Abstract: Techniques for automatically analyzing neural activity within a target neural region. In one example, electrical stimulation is applied to the target neural region at an initial current level that approximates a typical threshold-Neural Response Telemetry (NRT) level. An NRT measurement of neural activity within the target neural region in response to the stimulation is recorded. A machine-learned expert system, which is configured with a decision tree that includes at least two levels of nodes which consider parameters relating to the NRT measurement, respectively, is utilized to predict, based on one or more features of the neural activity, whether the NRT measurement includes a neural response or does not include a neural response.Type: GrantFiled: July 5, 2017Date of Patent: October 22, 2019Assignee: Cochlear LimitedInventors: Andrew Botros, Matthijs Killian, 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. Parker, James F. Patrick, Ernst von Wallenberg
