  • Patent number: 12266337
    Abstract: Managing noise during an online conference session includes obtaining audio data from an endpoint participating in an online conference session. The audio data is derived from audio captured at the endpoint that includes musical sounds. The audio data is processed to identify a portion of the audio data in which a decibel level of the musical sounds is stable for a period of time. Non-musical noise present, if any, in the audio data with the musical sounds is identified and the non-musical noise is attenuated from the audio data to generate noise-reduced musical audio data. The noise-reduced musical audio data is transmitted for play out at one or more other endpoints participating in the online conference session.

  • Patent number: 12260965
    Abstract: An automatic leveling type maintenance platform for a high-temperature gas cooled reactor is provided. A floating plate is automatically leveled by using a leveling liquid. During leveling, only a water driving assembly needs to be controlled to drive a housing to be close to an inner bottom surface of a liquid storage container. A sliding block assembly and a lifting guide mechanism are controlled to be locked and fixed after the floating plate is leveled. The floating plate can allow for automatic and rapid leveling and locking operation. Thus, complex and time-consuming fine adjustment control does not need to be performed. Also, when the platform is used in a spherical top cap of a pressure vessel of the reactor for a maintenance operation, then support legs of a support assembly do not need to have telescopic motion.
