Patent number: 8190267Abstract: The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual subject. The response to electrical neural stimulation varies from subject to subject. Measure of impedance may be used to predict the electrode height from the neural tissue and, thereby, predict the threshold of perception. Alternatively, electrode height may be measured directly to predict the threshold of perception. Also, impedance measurement may be used to quickly identify defective electrodes and proper electrode placement.Type: GrantFiled: October 26, 2007Date of Patent: May 29, 2012Assignee: Second Sight Medical Products, Inc.Inventors: Robert J. Greenberg, Ione Fine, Arup Roy, Matthew J. McMahon, Mark S. Humayun, James David Weiland, Alan M. Horsager, Dao Min Zhou, Amy Hines, Sumit Yadav, Rongqing Dai

Publication number: 20120059697Abstract: A system and a method are disclosed for displaying an image during an operation of an accelerated media playback (e.g., fast-forward or reverse) such that the image appears concurrently with a cue signaling a resume point. First, a video frame within an advertisement is identified from a plurality of advertisements. The video frame contains the cue and indicates a resume point for media content. Additionally, an image is embedded on the video frame such that the video frame, the cue and the image are displayed for less than a second during accelerated media playback, such as a fast-forward operation. The presence of the action cue or resume cue presented concurrently with the advertisement assists viewers in preferentially recalling the product related to the image.Type: ApplicationFiled: May 7, 2010Publication date: March 8, 2012Applicant: UNIVERSITY OF WASHINGTONInventors: Jeffrey Y. Lin, Ione Fine, Geoffrey M. Boynton, Scott O. Murray

Publication number: 20110184490Abstract: The present invention is a method of stimulating visual neurons to create the perception of light. A visual prosthesis electrically stimulating the retina with implanted electrodes exhibits interaction between electrodes stimulated closely together in both space and time. The method of the present invention includes determining a minimum distance at which spatiotemporal interactions occur, determining a minimum time at which spatiotemporal interactions occur, and avoiding stimulation of electrodes within the minimum distance during the minimum time. The minimum are ideally established for each individual patient. Alternatively, approximate minimums have been established by the applicants at 2 mm and 1.8 ?sec.Type: ApplicationFiled: January 27, 2011Publication date: July 28, 2011Inventors: Alan Matthew Horsager, Geoffrey M.

Patent number: 7908011Abstract: Methods and devices for fitting a visual prosthesis are described. In one of the methods, threshold levels and maximum levels for the electrodes of the prosthesis are determined and a map of brightness to electrode stimulation levels is later formed. A fitting system for a visual prosthesis is also discussed, together with a computer-operated system having a graphical user interface showing visual prosthesis diagnostic screens and visual prosthesis configuration screens.Type: GrantFiled: October 29, 2007Date of Patent: March 15, 2011Assignee: Second Sight Medical Products, Inc.Inventors: Matthew J.

Publication number: 20110015699Abstract: The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual patient. The perceptual response to electrical neural stimulation varies from patient to patient and The response to electrical neural stimulation varies from patient to patient and the relationship between current and perceived brightness is often non-linear. It is necessary to determine this relationship to fit the prosthesis settings for each patient. It is advantageous to map the perceptual responses to stimuli. The method of mapping of the present invention is to provide a plurality of stimuli that vary in current, voltage, pulse duration, frequency, or some other dimension; measuring and recording the response to those stimuli; deriving a formula or equation describing the map from the individual points; storing the formula; and using that formula to map future stimulation.Type: ApplicationFiled: September 10, 2010Publication date: January 20, 2011Inventors: Robert Jay Greenberg, Ione Fine, Arup Roy, Matthew J.

Publication number: 20100241192Abstract: To accurately represent a visual scene a visual prosthesis must convey luminance information across a range of brightness levels. To do this, the brightness of phosphenes produced by an individual electrode should scale appropriately with luminance, and the same luminance should produce equivalently bright phosphenes across the entire electrode array. Given that the function relating current to brightness varies across electrodes, it is necessary to develop a fitting procedure that will permit brightness to be equated across an entire array. The current invention describes a method of performing a brightness fitting that normalizes brightness across electrodes. The method determines a set of parameters that are stored in the subjects Video Configuration Fileāthe look-up table that converts the video camera input to stimulation profiles for each electrode. One electrode would be specified as the standard.Type: ApplicationFiled: September 16, 2009Publication date: September 23, 2010Inventors: Scott H. Greenwald, Matthew J. McMahon, Ione Fine
