Patent number: 12252898Abstract: The present invention relates to a prefabricated infilled panel-frame structure capable of accommodating seismic-loading and seismic energy dissipation, and a construction method thereof, including a frame body, a prefabricated infilled panel group, a panel connector, and a disc spring assembly. During an earthquake, the present invention slides to dissipate energy only after the maximum starting sliding force is exceeded, thus providing the structure with a relatively high lateral stiffness prior to sliding. After an earthquake, the disc spring assembly of the present invention may provide a certain restoring force due to being compressed so as to reduce the residual displacement. Further, the present invention achieves the bidirectional deformation cooperation of the prefabricated infilled panel under earthquakes, so that the infilled panel may still achieve the function of seismic energy dissipation under the coupling action of in-plane and out-of-plane loads.Type: GrantFiled: March 24, 2023Date of Patent: March 18, 2025Assignees: SOUTH CHINA UNIVERSITY OF TECHNOLOGY, CHINA CONSTRUCION FOURTH ENGINEERING DMSION GREEN BUILDING TECHNOLOGY (GUANGDONG), LTD, CHINA CONSTRUCTION FOURTH ENGINEERING DIVISION CORP.

Patent number: 9723138Abstract: From one perspective, an apparatus receives a request for a calling terminal device to initiate a session with a called terminal device. Based on the request, the apparatus obtains a storage address of the multimedia resource, and sends the address to the called terminal device. Based on sending the address the apparatus receives, from the called terminal device, a message indicating the called terminal device is playing the multimedia resource, and a message indicating that the called terminal device is off-hook. The called terminal device stops playing the multimedia resource when off-hook. From another perspective, a terminal device receives a storage address of a multimedia resource from a service management entity. The terminal device downloads the multimedia resource from a resource storage entity, and plays the multimedia resource as part of ringing, and before detecting that it is off-hook. The terminal device ceases playback after detecting it is off-hook.Type: GrantFiled: October 6, 2014Date of Patent: August 1, 2017Assignee: INVT SPE LLCInventor: Junxian Zhao
