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.
