  • Patent number: 9597495
    Abstract: The invention is a method of identifying a preferred location for an electrode array to the neural characteristics of an individual subject. The response to electrical neural stimulation varies from subject to subject and array location to array location. Measure of impedance may be used to predict the electrode height from the neural tissue and, thereby, predict the preferred location. Alternatively, electrode height may be measured directly to predict the preferred location.

  • Publication number: 20150335892
    Abstract: A visor for visual stimulation of visually impaired subjects is shown. The visor comprises a frame, a coil, a camera and a mounting system. A connector allows the coil to be positioned along a first direction. A sliding device allows the coil to be positioned along a second direction. Positioning of the visor on a subject's nose allows the coil to be positioned along a third direction. Positioning of the coil along the first, second or third direction is useful to maximize coupling RF coupling between the coil and an internal coil implanted on a subject wearing the visor.
