—The electric potential pattern generated by a cochlear implant was modeled using the finite-element method. The pattern , which is a response to bipolar current pulses from the implant electrode array, was investigated for different values of the electrical parameters of the human cochlea and of the array. Simulated data are compared with measurements in a(More)
Hearing aid shells (or earmolds) must couple the hearing aid with the user's ear. Earmolds have to fit the subject's outer ear canal properly to ensure a good performance of the aid. Because of the great variability in the anatomical pattern of the ear, earmolds are custom made. At present, an impression of the subject's ear canal is taken and used to(More)
A smart monitoring system for superconducting cable test is proposed with an adaptive current control of a superconducting transformer secondary. The design, based on Fuzzy Gain Scheduling, allows the controller parameters to adapt continuously, and finely, to the working variations arising from transformer nonlinear dynamics. The control system is(More)
—The experimental setup for the measurement of the current pulses generated at the different electrodes of a cochlear implant is presented. The electrical stimuli were modulated by an ad hoc software, transferred through a custom-made cochlear-implant programming interface to the speech processor, encoded as radio frequency (RF) signals, delivered via coil(More)
