    摘要: A visual prosthesis apparatus and a method for limiting power consumption in a visual prosthesis apparatus. The visual prosthesis apparatus comprises a camera for capturing a video image, a video processing unit associated with the camera, the video processing unit configured to convert the video image to stimulation patterns, and a retinal stimulation system configured to stop stimulating neural tissue in a subject's eye based on the stimulation patterns when an error is detected in a forward telemetry received from the video processing unit.

    摘要: The present invention is a method of improving the persistence of electrical neural stimulation, and specifically a method of improving the persistence of an image supplied to a retina, or visual cortex, through a visual prosthesis. A continuously stimulated retina, or other neural tissue, will desensitize after a time period in the range of 20 to 150 seconds. However, an interruption of the stimulation on the order of a few milliseconds will restore the retinal sensitivity without the user perceiving the interruption, or with the user barely perceiving the interruption.

    摘要: A visual prosthesis apparatus and a method for providing artificial vision are disclosed in the present disclosure. The visual prosthesis apparatus comprises a camera for capturing a video image, a video processing unit configured to convert the video image to stimulation patterns, and a retinal stimulation system configured stimulate neural tissue in a subjects eye based on the stimulation patterns. An artificial vision may be provided by capturing a video image, converting the video image to stimulation patterns, and stimulating neural tissue in a subjects eye based on the stimulation patterns.
