  • Patent number: 12458988
    Abstract: The present disclosure discloses a water outlet mechanism comprising a water outlet body, a driving assembly, an eccentric cam, a swinging plate, and one or more water outlet nozzles. The water outlet body comprises a water inlet port, a water outlet port, and a water-passing cavity in communication with the water inlet port and the water outlet port. The driving assembly is disposed in the water-passing cavity. The eccentric cam is rotatably disposed in the water-passing cavity and is operatively coupled to the driving assembly. The swinging plate is swingingly disposed in the water-passing cavity and is operatively coupled to the eccentric cam. The one or more water outlet nozzles are swingingly disposed on the swinging plate and are configured to be driven by the swinging plate to perform reciprocating movement of swinging in a front-and-rear direction.

  • Patent number: 12445474
    Abstract: An illustrative method includes scanning a compute environment associated with an entity and identifying one or more attack paths from a network to one or more datasets associated with the entity. The one or more attack paths each include a series of risk artifacts within the compute environment that can be exploited by an attacker to access the one or more datasets. The method further includes generating one or more attack path risk scores associated with the one or more attack paths and indicative of one or more levels of risk that the one or more attack paths could be exploited to access the one or more datasets. A risk mitigation operation associated with the one or more attack paths is performed based on the one or more attack path risk scores.
