    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: Techniques and functional electrical stimulation to eliminate discomfort during electrical stimulation of the retina are provided. According to a first technique, discomfort is eliminated through control of timing group assignment. According to a second technique, discomfort is eliminated through an edge detection method. According to a third technique, brightness clipping is used to eliminate discomfort. According to a fourth technique, direct reduction of current is obtained by scaling it down by a factor which is dependent on the sum of current in all electrodes. According to a fifth technique, the current being fed to each electrode is adjusted, by dividing it by a weighted sum of currents fed to the surrounding electrodes. According to a sixth technique, a method based on the current summation effect is used. According to a seventh technique, a large return electrode is used. According to an eighth technique, the return electrode is used for a pseudo-multi-polar stimulation.
