Within the human larynx, the ventricular folds serve primarily as a protecting valve during swallowing. They are located directly above the sound-generating vocal folds. During normal phonation, the ventricular folds are passive structures that are not excited to periodical oscillations. However, the impact of the ventricular folds on the phonation process(More)
Standard laryngoscopic imaging techniques provide only limited two-dimensional insights into the vocal fold vibrations not taking the vertical component into account. However, previous experiments have shown a significant vertical component in the vibration of the vocal folds. We present a 3D reconstruction of the entire superior vocal fold surface from 2D(More)
Two concepts for drive-integrated contactless energy transfer from the stator to the rotor of an electric motor are presented in this paper. Both drive systems offer the possibility of not only producing torque on the motor shaft, but also to power a rotating load. The power transfer is realized using the magnetic air gap fields. Problems inherent to(More)
