  • Patent number: 11224746
    Abstract: In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation, which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue is not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes, as continued use may result in neural damage and further electrode damage. The present invention presents system and stimulator control mechanisms to prevent damage to neural tissue.

  • Patent number: 10625078
    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.
