  • 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: 9492663
    Abstract: A method of editing a video configuration file downloadable to or from a video processing unit of a fitting system for a visual prosthesis is shown. The visual prosthesis has a plurality of electrodes and the video configuration file defines mapping of a video signal captured from a camera of the visual prosthesis to an electrical signal for the electrodes. The editing controls a brightness map for an individual electrode or electrode groups, together with a temporal stimulation pattern to which an individual electrode or electrode groups are assigned. A related computer-operated system is also disclosed.

  • Patent number: 9002462
    Abstract: The present invention is an improved method of providing flexible image possessing in a visual prosthesis by providing downloadable video filters. In a visual prosthesis, the input video image is normally higher resolution than the output stimulation of the retina, optic nerve or visual cortex. It is advantageous to apply video processing algorithms (filters) to help provide the most useful information to the lower resolution electrode array. Different filters are more effective in different environments and for different subjects. Examples of situation dependent filters include reverse image, contrast increasing, edge detection, segmentation using chromatic information and motion detection. Filters loaded in the video processing unit may be selected dynamically to suit the situation or the user's preference. It is therefore advantageous to provide flexibility in applying filters. However, it is also important to maintain the security necessary for a medical device.

  • Patent number: 8571668
    Abstract: The present invention is a method of neural stimulation and more specifically an improved method of providing flexible video/image possessing in a visual prosthesis by providing downloadable video filters. In a visual prosthesis, the input video image will, for the foreseeable future, be higher resolution than the output stimulation of the retina, optic nerve or visual cortex. This is due to limits of electrode array technology and the rapid advancement of video camera technology. It is therefore, advantageous to apply video processing algorithms (filters) to help provide the most useful information to the lower resolution electrode array. Different filters are more effective in different environments and for different subjects. Furthermore, filters will continue to improve over time. Examples of situation dependent filters include reverse image, contrast increasing, edge detection, segmentation using chromatic information and motion detection.
