Abstract: A packaging piece is disclosed. The packaging piece includes a first side that includes a first module frame interlocking structure configured to snap fit to a drainage hole of a module frame in a first orientation and to extend toward a glass surface of a module in a second orientation. The packaging piece also includes a second side that includes: a second module frame interlocking structure configured to extend toward the glass surface of the module in the first orientation and to snap fit to the drainage hole of the module frame in the second orientation.

Abstract: A seafloor observation network-based subsurface buoy device with real-time power supplying and high-speed data transmitting is provided. The subsurface buoy device includes a seabed base deployed on the seafloor and a vertical mooring system connected to a bottom surface of the seabed base to extend to the sea surface. The seabed base serves as a gravity anchor to enable the subsurface buoy device to be positioned stably at a layout site, and is further used for obtaining power supply of the subsurface buoy device from a junction box of a seafloor observation network. The seabed base also sends the management and control commands from the junction box to the vertical mooring system, and transmits the data collected by the vertical mooring system back to the junction box in real time.

Abstract: A module clip piece for a module is disclosed. The module clip piece includes at least one protrusion configured to engage at least one groove of a first neighboring module clip piece. The at least one protrusion protrudes in a first direction. At least one groove is coupled to the at least one protrusion and is configured to engage at least one protrusion of a second neighboring module clip piece. The at least one groove extends in a second direction that is orthogonal to the first direction.

Abstract: A blood flow environment simulation device is disclosed, including: a liquid reservoir (1) for storing liquid; a vascular simulation tube (4); a pump (2) for pumping liquid; a plurality of circulation tubes (7, 11, 12), which form a liquid circulation path together with the vascular simulation tube; and a valve (6) located in the circulation path, having a valve inlet (17) and a valve outlet (18), wherein the area of the valve inlet (17) is variable to change the dynamic parameters of the fluid in the vascular simulation tube (4) over time. The present disclosure also relates to medical equipment that includes a blood flow environment simulation device as described.

Abstract: Disclosed is a combined submarine seismic acquisition node with a secondary positioning function, including an ocean bottom node connected with an external loading ship; a protective sleeve circumferentially covering outside the ocean bottom node; and response components fixed inside the ocean bottom node, and the response components are configured to send position information of the ocean bottom node, and the response components may perform an information interaction with the loading ship.

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.
