Abstract: This application provides a method for performing inter-app data synchronization in a service management platform. The method includes: creating a state machine for a platform virtual room containing a target object in the service management platform; creating a service virtual room in an application through the state machine, and adding the target object into the service virtual room; receiving service progress data of the target object in the service virtual room through the state machine and updating the state machine accordingly to obtain a state-updated state machine; and performing data synchronization processing on the platform virtual room according to the state-updated state machine and the service progress data of the service virtual room so as to synchronize object service information of the target object in the service virtual room into the platform virtual room.

Abstract: Disclosed is an atrial appendage clip, including a first clip arm and a second clip arm that are symmetrically arranged; a first cavity and a second cavity are correspondingly provided in the first clip arm and the second clip arm along an axial direction thereof; a first spring and a second spring are correspondingly provided in the first cavity and the second cavity; the first spring is connected with the second clip arm via a first pull wire, and the second spring is connected with the first clip arm via a second pull wire, so as to form a closed loop structure; and as the first spring and the second spring are stretched or compressed, the first clip arm and the second clip arm are opened or closed therebetween.

Abstract: Disclosed is an atrial appendage clip delivery system, which includes a handle shell, a push rod, a connection pipe and a support base; a passage is provided in the handle shell along a length direction; one end of the push rod is slidably disposed in the passage; the support base is provided with a mounting window for mounting an atrial appendage clip; the atrial appendage clip includes a first clip arm and a second clip arm capable of opening in parallel or closing; the handle shell, the connection pipe and the support base are sequentially connected and communicate; the first clip arm or the second clip arm is fixedly connected with an upper side or a lower side of the mounting window; the second clip arm or the first clip arm is movably connected with the lower side or the upper side of the mounting window.

Abstract: A buckling-restrained brace with a flat energy dissipation element, a building with the brace and an assembly method of the brace belongs to the field of force-resisting members of structural engineering. The brace includes a telescopic inner restrained member, an outer restrained member sleeved outside the inner restrained member, and the flat energy dissipation element between the inner and outer restrained members; the inner restrained member includes a first and a second steel square tube which are connected; the flat energy dissipation element includes four flat fuses, and two ends of each fuse are connected to four sides of the first and second steel square tube by bolts; and the inner section of the outer restrained member is square, the outer restrained member covers the flat energy dissipation element, and a certain gap is disposed between the outer restrained member and the flat energy dissipation element.

Abstract: Some embodiments of the present disclosure provide an integrated electrode, the integrated electrode includes an electrode wire and an electrode base. The electrode wire is provided in a hollowed-out shape, and several through holes are punched on a side face of the electrode wire without changing the appearance and dimension of the electrode wire. The electrode base is formed by an injection molding process, and is integrally connected with the electrode wire by means of a one-time injection molding. During a process of injection molding, plastic fluid can flow through the hollowed-out through holes of the electrode wire so as to fix the electrode wire in the electrode base, such that the electrode wire and the electrode base are integrated.

Abstract: A device is configured to control display of a live broadcast of an interactive multi-user activity session in a network application. The device receives a user request for triggering an interactive live broadcast in the network application and obtains a live broadcast page for interaction in the network application from a server end. The computing device then causes display of the live broadcast page on a display located at a public broadcast location. The interaction in the network application is to be performed among users corresponding to user terminals that are located in proximity to the public broadcast location. The computing device obtains, in real time by using a persistent connection established to the server end, an update message corresponding to a dynamic change in user data in the interaction in the network application. The computing device updates display of the live broadcast page according to the update message.
