  • Patent number: 11956257
    Abstract: A method for classifying domains to malware families includes identifying a corpus of malicious domains, identifying one or more suspicious domains, extracting a timeframe corresponding to the one or more suspicious domains, calculating a rank coefficient between the one or more suspicious domains and a current seed domain of the corpus of malicious domains, determining whether the rank correlation coefficient exceeds a rank threshold for the one or more suspicious domains, comparing a number of suspicious domains whose correlation coefficients exceed the rank threshold to a relation threshold, and responsive to determining the number of suspicious domains whose correlation coefficients exceed the rank threshold exceeds the relation threshold, applying a tag to the suspicious domains indicating that the one or more suspicious domains correspond to a same malware family as the current seed domain.

  • Publication number: 20220312047
    Abstract: A network-based system for live media broadcasting includes a server system including processing structure configured to: receive at least one live non-WebRTC media stream; ingest the at least one live non-WebRTC media stream; transcode the at least one live non-WebRTC media stream to generate a WebRTC-compatible media stream; publish the WebRTC-compatible media stream to a WebRTC gateway of the server system using Real Time Streaming Protocol (RTSP); and using the WebRTC gateway of the server system, stream the WebRTC-compatible media stream to a requesting client computing device over a respective WebRTC connection for selectively mixing using the requesting client computing device. Various related systems, devices and methods are provided.

  • Patent number: 11388449
    Abstract: A network-based system for live media broadcasting includes a server system including processing structure configured to: deploy processor-executable program code executable on a requesting client computing device for provisioning the requesting client computing device with a browser-based mixing user interface for selective mixing in the browser using at least one media stream received by the requesting client computing device from the server system to generate a mixed video stream and at least one associated audio stream; the processing structure further configured to: receive one or more live media streams from other client computing devices; stream media data from the one or more live media streams to the requesting client computing device over at least one live streaming media connection; and receive, from the requesting client computing device, the mixed video stream and the at least one associated audio stream. Various related systems, devices and methods are provided.

  • Patent number: 9803708
    Abstract: This invention relates to a braking device (10) for a passenger conveyor comprising at least one movable part (12). The braking device (10) comprises a braking element (18) having a braking portion (34) engageable with the movable part (12) of the passenger conveyor. The braking element (18) is movable in a first direction into a position in which the braking portion (34) engages with said movable part (12) of the passenger conveyor. The braking element (18), in a state in which the braking portion (34) engages with the movable part (12) of the passenger conveyor, is movable in a second direction from a position of initial engagement of the braking portion (34) into a braking position of the braking element (18). The movement in the second direction is driven by movement of the movable part (12) of the passenger conveyor.
