Abstract: Disclosed are a spring portable decorative box and a foldable supporting column. The spring portable decorative box includes two frame bodies arranged up and down, a plurality of foldable supporting columns are arranged between the two frame bodies, the frame bodies and the supporting columns form a stereoscopic supporting skeleton of a gift box, a lock structure is arranged between the two frame bodies, the supporting column comprises two connecting rods and a spiral spring fixedly connected between the two connecting rods, the two connecting rods are both located on an axis of the spiral spring to make the two connecting rods and the spiral spring form a straight line, a pitch of a middle part of the spiral spring is smaller than pitches of two ends, when the two frame bodies approach to form a folded state and the lock structure above is locked.

Abstract: A primary node of a seafloor observatory network based on constant current power supply is provided. The primary node is connected in series to a submarine cable of a backbone network. The primary node is connected to a shore station and an adjacent primary node by submarine cable terminal boxes, respectively. The primary node includes an underwater power supply and a communication control module. The underwater power supply is used for converting constant current power provided by the shore station into power for the primary node and some backup power, and outputting direct-current constant voltage power for the communication control module, and is further used for controlling the primary node to access and exit from the network. The communication control module is used for monitoring the internal state of the primary node by control system backup, and sending the state information and data to the shore station.

Abstract: A computer-implemented method for searching information and an electronic device are disclosed. The method includes: receiving, at one or more computing devices, a search term; acquiring, at the one or more computing devices, a 3D search result corresponding to the search term if the search term includes a 3D search requirement, in which the 3D search result includes a 3D picture and one or more service items corresponding to the 3D picture; displaying, at the one or more computing devices, the 3D search result; determining, at the one or more computing devices, a service item selected by a user; and processing, at the one or more computing devices, the 3D picture according to the service item. The method can provide a service on the basis of the 3D search result when the user has the 3D search requirement, thereby better satisfying the user' requirement and improving the user experience.
