  • Patent number: 12149866
    Abstract: A videoconferencing system receives audio and/or video signals (“AV”), information, and control signals from meeting participants. The videoconferencing system processes and routes the received AV and information, based on the received control signals, to provide AV and information to meeting participants. The videoconferencing system enables participants to know details about breakout room (e.g., what breakout rooms are available, how many people are attending each breakout room, who is attending each breakout room, the topics of the breakout rooms), hear audio, see video, and receive information corresponding breakout rooms that they have not joined, join a breakout room, leave a breakout room, create breakout rooms, invite other participants to join a breakout room, and make a breakout room private.

  • Patent number: 10954492
    Abstract: Described are improved processes for production and purification of nucleic acid-containing compositions, such as non-naturally occurring viruses, for example, recombinant polioviruses that can be employed as oncolytic agents. Some of the described improved processes relate to improved processes for producing viral DNA template. Also described are improved processes for chromatography purification of nucleic acid-containing compositions, in which the nucleic acid is quantified in chromatography fractions using a rapid detection method of the one or more nucleic acid sequences of the nucleic acid-containing composition, such as detection by real time RT-qPCR. In addition, improved processes for production and purification of oncolytic poliovirus, such as PVS-RIPO, are described. Compositions generated using these methods are also provided.

  • Patent number: 10163586
    Abstract: Embodiments relate generally to methods and systems for providing a bias mechanism for a momentary toggle switch. A toggle switch may comprise a housing; a plurality of contacts disposed within the housing; an actuating lever coupled to a pivot pin, wherein the actuating lever extends into the housing; an actuator assembly coupled to the actuating lever, configured to actuate a movable contact of the plurality of contacts between a first position and a second position; and a biasing mechanism configured to bias the actuator assembly into the first position, wherein the biasing mechanism comprises a torque spring.

  • Patent number: 8992082
    Abstract: An X-ray imaging apparatus is provided having advantages of both C-shaped, G-shaped, and ring-shaped arm configurations. The device consists of a gantry that supports X-ray imaging machinery. The gantry is formed to allow two bi-planar X-rays to be taken simultaneously or without movement of the equipment and/or patient. The gantry is adjustable to change angles of the X-ray imaging machinery. Further, in some embodiments, the X-ray receptor portion of the X-ray imaging machinery may be positioned on retractable and extendable arms, allowing the apparatus to have a larger access opening when not in operation, but to still provide bi-planar X-ray ability when in operation.

  • Publication number: 20140344218
    Abstract: Architecture that provides the ability to intelligently page (slice) hierarchical datasets through viewing operations of a hierarchical view. This further provides the capability to make additions to/deletions from the hierarchy view and manage the parent/child relationship of view records without ever sending the entire recordset to the client or receiving the entire recordset back to the server, thereby optimizing operation performance on the hierarchical datasets.
