  • Publication number: 20230245658
    Abstract: Methods and systems provide an asynchronous pipeline for artificial intelligence service requests. In one embodiment, the system receives, at a gateway service, access to content associated with a communication session; sends, to an artificial intelligence (AI) cluster including a number of AI services, a data payload, the data payload including a location to access the content and a number of requests for AI services to be performed by one or more AI models hosted on the AI cluster using the content as an input; receives one or more AI service results as the AI cluster completes the corresponding requests for the AI services; and stores each received AI service result in one or more databases.

  • Publication number: 20220247866
    Abstract: Voicemail spam detection is performed based on content of voicemail messages. The content of an incoming voicemail message is compared to a spam template that includes a representation of a spam voicemail. Spam templates may be generated based on spam indications provided by users for voicemail messages they have received. User indications for sufficiently similar voicemail messages may be aggregated by maintaining a vote count for a spam template that reflects how many times a user has indicated a matching voicemail message is spam. A spam template may also include an occurrence count that reflects how many times voicemail messages matching a spam template have been detected in a telephony system. An incoming voicemail message may be compared to spam templates and, responsive to a match of content and/or a corresponding vote count or occurrence count meeting a condition, the voicemail message may be identified as spam.

  • Publication number: 20190011855
    Abstract: A toner outlet device for a toner cartridge includes: a top lid (1) and a driving claw (2) arranged on the top lid (1), wherein the top lid (1) is in clearance fit with the driving claw (2); a rotary lid (3) is rotatably arranged inside the top lid (1); the driving claw (2) is clutched on the rotary lid (3); a toner outlet (4) on the rotary lid (3) is selectively connected to a side opening (5) of the top lid (1); a driving head (6) is arranged on a top portion of the top lid (1); the driving head (6) transmits a torsion to the driving claw (2) through the rotary lid (3). The toner outlet device for the toner cartridge reduces resistance for pulling out the driving claw (2), and is easy to operate.

  • Patent number: 10061228
    Abstract: A stop transmission mechanism includes: a ratchet, wherein elastic teeth are provided on a periphery of the ratchet; a claw provided at a radical side of the ratchet, comprising a fixed end and a moving end which rotates around the fixed end, wherein a claw portion to be engaged with the elastic teeth is provided on the moving end; and a tension spring, wherein one end of the tension spring is fixed, and the other end of the tension spring is mounted on the moving end of the claw, for providing a force which drives the claw portion towards the ratchet; wherein the elastic teeth are made of an elastic material; when the claw portion of the claw is buckled on the elastic teeth by the force of the tension spring, the ratchet is flexibly fixed; when external driving force is large enough, sliding tooth happens.

  • Patent number: 8058417
    Abstract: Production and use of a sulfur-containing compound, tropodithietic acid (TDA), from the roseobacter Silicibacter sp. TM1040 is described. Specifically, a biosynthetic and regulatory pathway for TDA biosynthesis in roseobacters is described. The TDA produced from roseobacters, specifically Silicibacter sp. TM1040, is shown to have antibacterial activity, in particular against Vibrio anguillarium, Vibrio cholerae, Vibrio coralliilyticus, Vibrio shiloi, Halomonas spp., Mycobacterium marinum, Mycobacterium tuberculosis, Pseudomonas elongate, Spongiobacter nikelotolerans, and Staphylococcus aureus (MRSA).
