  • Publication number: 20220275611
    Abstract: The present disclosure discloses a water outlet device comprising an inlet passage, a first outlet passage, a second outlet passage, a third outlet passage, a first valve chamber, a second valve chamber, a first sealing member, a second sealing member, and a first resetting member. When the second sealing member is controlled to move and to be changed from blocking the second outlet passage to blocking the third outlet passage, the first sealing member is correspondingly changed from blocking the second valve chamber to blocking the first outlet passage, and the first sealing member continues blocking the first outlet passage due to water pressure. When the inlet passage is blocked, the first sealing member is biased by the first resetting member to move to block the second valve chamber.

  • Publication number: 20220116421
    Abstract: Systems, methods, and computer-readable media for gathering network intrusion counter-intelligence. A system can maintain a decoy network environment at one or more machines. The system can identify a malicious user accessing network services through the network environment. Further, the system can receive network service access requests from the user at one or more machines in the network environment and subsequently direct the network service access requests from the malicious user to the decoy network environment based on an identification of the malicious user. The network services access requests can be satisfied with network service access responses generated in the decoy network environment. Subsequently, the system can maintain malicious user analytics based on the network service access requests of the malicious user that are directed to the decoy network environment.

  • Publication number: 20190193988
    Abstract: The present invention relates to automatic elevator call control, and belongs to the field of elevator intelligent control technologies. An automatic elevator call system provided in the present invention calculates duration information from the moment when the personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again, and when the duration information is less than or equal to a preset time threshold, causes the personal mobile terminal to be incapable of automatically sending an elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again. The present invention can effectively avoid invalid or abnormal elevator call request operations, and the elevator system achieves high running efficiency.
