  • Patent number: 11759714
    Abstract: A method for user matching is provided. A matching request is received from a client. The matching request includes an application identifier and a user identifier. When the application identifier indicates that a matching mode for the matching request is an asynchronous mode, a matching queue identifier is obtained based on the matching request, the user identifier is added to a matching queue corresponding to the matching queue identifier, a predetermined number of user identifiers is selected from the matching queue, a matching result is generated that includes an identifier of a matching group of the selected predetermined number of user identifiers, and the matching result is sent to the client. The predetermined number of user identifiers includes the user identifier in the matching request.

  • Patent number: 11314703
    Abstract: Methods and apparatus for processing timedly-published data are provided. After receiving an operation request for the timedly-published data, at least one of an append-file and a delete-file can be written according to the operation request. The append-file corresponds to to-be-appended timedly-published data or post-updated timedly-published data. The delete-file corresponds to to-be-deleted timedly-published data or pre-updated timedly-published data. Each of the append-file and the delete-file uses a publishing time of the timedly-published data as an index.

  • Patent number: 10317861
    Abstract: A switch drive circuit for a fan processor is applied to a fan processor. The switch drive circuit includes multiple upper arm switch components, multiple lower arm switch components correspondingly electrically connected with the upper arm switch components, a first drive switch unit and a second drive switch unit. The upper arm switch components are driven by a first pulse width modulation signal and a second pulse width modulation signal. The first and second drive switch units serve to receive a third pulse width modulation signal and a high-frequency puke width modulation signal. The third pulse width modulation signal is switched between a voltage high-level state and a voltage low-level state to trigger and turn on the lower arm switch components.
