Abstract: This disclosure describes techniques for distributed storage of files that represent video content across different storage tiers to reduce the amount of computing resources used to store the files, while maintaining a low latency when responding to user requests to stream the video content. Video streaming services support the streaming of video content at different resolutions to support various user devices and/or user preferences. To provide streaming of a particular video content item at different resolutions, the video streaming services may store multiple files that represent the video content item for the different resolutions and stream at different bitrates to user devices. The techniques described herein include storing files configured to stream a video content item at different bitrates (and for different display resolutions) in a tiered storage structure to reduce the amount of computing resources taken to store the files.

Abstract: A first valve has a first input port and first and second output ports with the first output port adapted for connection to a drainage collection bag. A tube connects the input port of the first valve to a patient. A second valve has an input port connected to the second output port of the first valve. A dome member has a first opening for connection with an output port of the second valve, a second opening for receiving a pressure transducer, and a third opening for permitting balancing of the system. Through this configuration, the drainage collection bag is located before the pressure sensor, but at a maximum distance from the patient to reduce the risk of infection. An automatic relief valve may replace the second valve to provide for automatic venting of dangerously high levels of intracranial fluids.
