Abstract: The present invention discloses a stereo garage that comprises: a main body provided with a lifting shaft, wherein the lifting shaft is provided with an opening; a lifting platform located in the lifting shaft, wherein the lifting platform can ascend or descend in the lifting shaft along a height direction of the main body, such that the lifting platform can switch between an initial position and an end position, wherein the lifting platform can close the opening when the lifting platform is located in the initial position; an anti-falling device connected to the main body, wherein the anti-falling device comprises a blocking rod which can be switched between a locking position and an unlocking position; wherein, the blocking rod can block a movement of a vehicle when the blocking rod is located in the locking position, and the lifting platform can cause the blocking rod to be switched from the locking position to the unlocking position when the lifting platform comes into the initial position.

Abstract: This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.

Abstract: The invention provides for polymer structures and their preparation and resulting novel functionalities including open-shell character and high intrinsic conductivity with wide-range tenability. Electrical conductivity can be further modulated by introducing or blending with materials, fillers, dopants, and/or additives. The materials or resultant composites of the invention can be processed by various techniques into different forms to realize multiple applications.
