    摘要: A process for separating a primary gas component from a feed gas mixture comprising the primary gas component and secondary gas components in four or more adsorption beds. The process comprises subjecting each of the four or more adsorption beds to a repetitive cycle. The repetitive cycle comprises, in sequence, a feed step, a pressure decreasing equalization step, a provide purge step, a blowdown step, a purge step, a pressure increasing equalization step, and a repressurization step. During the pressure decreasing equalization step, rinse gas is co-currently introduced simultaneous with the withdrawal of pressure equalization gas. Rinse gas is formed by compressing blowdown gas and/or purge gas effluent from the adsorption bed undergoing the purge step. The process is particularly suited for separating H2 from a reformate stream.

    摘要: A live streaming system/method provides cross platform live streaming capabilities to mobile devices. The live streaming system includes a live streaming recorder operative to (1) capture a live media stream generated by a live media source and save the captured live media stream as a recorded stream in a recorded media file, and (2) transcode the recorded stream into a plurality of transcoded media files of respective different media encoding formats. The system further includes a stream distribution subsystem operative to generate a plurality of distributed media streams each generated from one or more of the transcoded media files, each distributed media stream being delivered to a corresponding set of the mobile endpoint devices.

    摘要: In a system for streaming data over a network, the type and rate of streaming are automatically varied based on available network bandwidth. Video media is transcoded into different bit rate encodings that are divided into segment files. Segments are sent from a network-aware adaptive streaming (NAAS) server and reassembled and presented to a media player at a client device. The system may download additional segment files ahead of time from multiple NAAS servers to increase throughput. A playback status (“bookmark”) may be maintained to keep track of what the user has viewed and to allow the user to continue playing from where the user left off. The user may continue watching from the bookmark point on the same device or on a different device.
