Abstract: A media content presentation system extends other devices' capability of sharing media content via a presentation device. A computing device, if coupled to a plug-in device of the media content presentation system, can present media content via the presentation device. The computing device provides the media content to the plug-in device via a proprietary communication channel established by the plug-in device. The plug-in device then passes the media content to the display device for presentation. The display device receives user input and provides the user input to the computing device for adjustment of the media content according to the user input.

Abstract: A central traction device for a straddling monorail train includes a traction pin and a traction beam. A central sleeve is provided at the center of the traction beam, and the traction pin is mounted in the central sleeve. An inner cavity of the central sleeve has a corset-shaped structure having large diameters on an upper end and a lower end and a small diameter at a middle part, forming double tapered bevels, and a resilient rubber bush is provided between an inner wall of the central sleeve and the traction pin. The device has a simple and compact overall structure and facilitates connection and separation between the train body and the bogie; by providing the lift assembly, the traction device is fixedly connected to the frame, thus the traction device can be wholly lifted; and operation process and environment of raising and lowering the vehicle are improved.
