Patent number: 9354615Abstract: A device for generating signal by detecting facial movement and operating method thereof is provided, which includes: an image capture unit, and a processing unit. The image capture unit for obtaining an image series. The processing unit receives the images series from the image capture unit, wherein the processing unit includes an image background removal module, an image extracting module, and a comparator, wherein the image background removing module processes each of the image series respectively to obtain a facial image, wherein the feature location module determines a location of a pair of nostrils in the facial image, defines a mouth searching frame, and acquires a data of mouth movements through the mouth searching frame, wherein the comparator compares the data of mouth movements with predetermined facial information, and generates a designated signal according to the comparison result.Type: GrantFiled: June 4, 2014Date of Patent: May 31, 2016Assignee: UTECHZONE CO., LTD.Inventors: Po-Tsung Lin, Chih-Heng Fang, Chia-Chun Tsou

Patent number: 9308368Abstract: A visual prosthesis must convey luminance information across a range of brightness levels to accurately represent a visual scene. Thus, the brightness of phosphenes produced by individual electrodes 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. A visual prosthesis that generates stimuli by performing a brightness fitting that normalizes brightness across electrodes is described.Type: GrantFiled: March 6, 2014Date of Patent: April 12, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Scott H Greenwald, Matthew J McMahon, Ione Fine
