Abstract: An example method of video conferencing includes: receiving, from a control sewer, an initiation package for a client account associated with a client device, the initiation package including a client participant identifier defining the client account within a video conferencing session, a base map, and a position of the client account on the base map; displaying, at the client device, the base map and a position marker on the base map, the position marker representing the position of the client account on the base map; obtaining a set of nearby participant identifiers representing nearby participant accounts selected based on a proximity of respective positions of the nearby participant accounts to the position of the client account; obtaining, based on the set of nearby participant identifiers, a set of media streams for the nearby participant accounts; and outputting the set of media streams at the client device.

Abstract: Methods and systems for allowing multiple devices to display and annotate (or modify) a video image are described, where a content renderer device displays a video image that is also displayed (or viewed) by one or more content viewer devices, which can both display and annotate (or modify) the same video image at the same time, and the content renderer selectively determines whether or not a GUI menu is displayed on its display screen. Annotation commands (e.g., screen touch data) on the viewer devices are captured, packaged and sent to the content renderer, which creates a combined modified video image having the annotations from the viewer devices, displays it to the renderer display and sends it to the viewer devices for display thereon.

Abstract: Embodiments of the invention feature methods and apparatus for the efficient utilization of detectors and other components. The apparatus comprises a pump for receiving and propelling one or more samples in a fluid path. The apparatus further comprises a valve element in fluid communication with the pump for receiving the samples from the pump and directing the sample along one fluid path selected from a group. The group comprises a delay path comprising a delay volume, and a chromatography assembly having at least one chromatography column. The apparatus further comprises a detector or grouping of detectors in fluid communication with the delay path and the chromatography assembly for detecting compounds of interest to allow a single detector or single grouping of detectors to receive samples from the two fluid paths.

Abstract: A liquid chromatography system comprising a chiral mobile phase used to separate enantiomeric molecules present in a sample is disclosed herein. In one aspect, the mobile phase comprises a chiral solvent. In another aspect, the mobile phase includes a chiral solvent but also a buffering agent. The liquid chromatography system described herein includes both high pressure liquid chromatography (HPLC) as well as high pressure capillary liquid chromatography (CapLC).

Abstract: A tube printer and method for printing information on an interior surface of a tube. The tube printer including a housing, an ink wheel assembly and a print wheel. The housing having at least two side members interconnected by a top plate extending there between and including spring biased guide wheels that cooperatively center the housing within the tube. An operating handle is operatively attached to an end of the housing to provide a means to push and pull the tube printer within the tube. The ink wheel assembly is operatively positioned between the side members of the housing and the print wheel is operatively positioned between the side members of the housing and adjacent the ink wheel and includes a raised surface containing the information to be printed on the interior surface of the tube.
