    • A method and apparatus for improving visual acuity when providing a visual image from a “high” resolution input device to a “low” resolution output device. The described invention is of particular use when the output device is an array of electrodes as part of a retinal prosthesis used to restore vision to a visually-impaired patient. In that various limitations may, within the foreseeable future, limit the density of such an electrode array (and thus the resolution of the output image), the present invention teaches techniques to assign processed pixel subsets of a higher resolution image to a single electrode. By varying the pixel subsets, e.g., by jittering, and/or altering the processing criteria, the perceived visual acuity may be further improved. Alternatively and additionally, such processing may be further extended to drive neighboring electrodes in combination to thus stimulate virtual electrode sites and thus further enhance visual acuity.
    • 当从“高”分辨率输入装置向“低”分辨率输出装置提供视觉图像时,用于提高视力的方法和装置。 当输出设备是用作将视力恢复到视觉障碍患者的视网膜假体的一部分的电极阵列时,所描述的本发明是特别有用的。 因此,在可预见的将来可能会限制这种电极阵列的密度(因此输出图像的分辨率)的各种限制,本发明教导了将更高分辨率图像的经处理的像素子集分配给单个电极的技术。 通过例如通过抖动和/或改变处理标准来改变像素子集,可以进一步改善感知的视敏度。 另外地和另外地,这样的处理可以进一步延伸以组合驱动相邻电极,从而刺激虚拟电极位置,从而进一步提高视敏度。

    • System, apparatus, and methods are directed to preventing a media player from playing a pirated media file, such as a pre-release motion picture. The invention treats the pirated media file as an infection and develops an immune system for the media player. The invention may be taught how to recognize an infection by using an immunization record for each media file that is to be treated as an infection. As the media file is played in real-time, a fingerprint is determined. A comparison is performed between the immunization records and the determined fingerprint. If a match is determined, then an alert may be provided. The alert may be employed to perform any of a variety of actions, including disabling the media player, sending a message to an owner of a digital right for the media file, and the like.
    • 系统,装置和方法旨在防止媒体播放器播放诸如预释放电影之类的盗版媒体文件。 本发明将盗版媒体文件视为感染,并为媒体播放器开发免疫系统。 本发明可以被教导如何通过使用将要被视为感染的每个媒体文件的免疫记录来识别感染。 当媒体文件被实时播放时,确定指纹。 在免疫记录和确定的指纹之间进行比较。 如果确定匹配,则可以提供警报。 可以采用警报来执行各种动作中的任何一种,包括禁用媒体播放器,向媒体文件的数字权利的所有者发送消息等。
