Abstract: The disclosure relates to a composite cathode frame assembly, a battery cell and an assembly method of the battery cell. The composite cathode frame assembly includes a frame, a cathode sheet and a separator sheet. An accommodating groove for embedding the cathode sheet is provided in the frame, both surfaces of the frame are matched with the separator sheet, and the separator sheet is attached to a surface of the frame and covers the cathode sheet and the frame. The battery cell includes the composite cathode frame assembly, a sleeve and an anode sheet. This disclosure has effect of reducing difficulty of manufacturing a battery cell on a premise of satisfying the battery cell overhang requirement.

Abstract: Methods and systems are provided for facilitating communications between an internal computing system and vehicle electronic control units. In some aspects, methods and systems are provided and can include receiving data from a plurality of vehicle electronic control units, the data from the plurality of vehicle electronic control units being processed by utilizing a control area network protocol, processing the data received from the plurality of vehicle electronic control units by utilizing a robotic operating system protocol, and providing robotic operating system data based on the data processed by utilizing the robotic operating system protocol to an internal computing system.

Abstract: A rollator having a first side frame and a second side frame; the first side frame comprising a first side frame intervening structural portion; the second rolling side frame comprising a second side frame intervening structural portion; a central platform having a first platform side and a second platform side; and first and second track mechanisms respectively coupling the first and second side portions to the first and second platform sides of the central platform; the first and second track mechanisms permitting independent movement of said first and second side frames relative to said central platform.

Abstract: A surgical visualization and tracking system includes including first and second tracking magnets and a sensor base assembly including a base and at least three magnetic sensor assemblies. Each of the magnetic sensor assemblies is configured to independently track each of the tracking magnets in X, Y, and Z dimensions. A control console is configured to receive tracking data from each of the magnetic sensor assemblies and determine position and orientation information for each of the tracking magnets based upon the received tracking data. A visualization system is configured to receive the position and orientation information from the control console and represent the position and orientation information for each of the first and second tracking magnets on a displayed 3D model of tissue.
