Abstract: A system for facilitating a virtual screening is disclosed. The system identifies a user for participating in a virtual screening of media content. The system generates a unique link for the user to facilitate access to the media content. When the user interacts with the link, the system prompts the user to authenticate with the system and determines whether the authentication was successful. If authentication is successful, the link is associated with an identifier of the user and/or a user device. A request for a key for decrypting the media content and a request for a digitally signed file accessing the media content pursuant to parameters are made. If the digitally signed file is valid, the system applies a watermark to the media content to track the use of the media content and streams the media content to the user. Feedback on the media content is obtained from the user.

Abstract: A deposition system for depositing a chemical vapor onto a workpiece is disclosed, including a deposition chamber having a plurality of components for performing chemical vapor deposition on the workpiece. The workpiece is held by a lathe that rotates the workpiece relative to chemical burners that deposit silica soot on the workpiece. The deposition system has a gas panel for regulating the flow of gases and vapors into the deposition chamber, and a computer for controlling operation of the gas panel and the components in the deposition chamber. Multiple sets of chemical burners are disposed longitudinally along the length of the workpiece. Each set of burners is separated from other sets, such that each set of burners deposit silica particles onto generally different portions of a workpiece. The respective portions include an overlap segment in which one or more burners from one burner set will deposit silica particles on the same portion of the workpiece as one or more burners from another set.
