    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.

    摘要: A process for the hydrogenation of a hydrocarbon feed includes contacting a major amount of the hydrocarbon feed with hydrogen in a counter-current manner in a first reaction zone under hydrogenation reaction conditions in the presence of a hydrogenation catalyst in at least a first catalyst bed wherein a liquid effluent exits at a bottom end of the first reaction zone and a hydrogen-containing gaseous effluent exits at a top end of the first reaction zone, and contacting a minor portion of the hydrocarbon feed with said hydrogen-containing gaseous effluent in a co-current manner in a second reaction zone having a catalyst bed positioned to receive the hydrogen-containing effluent of the first reaction zone.
