A method and system for transportation using a magnetic bearing structure is disclosed. The TFBs may be two-dimensional or three-dimensional. Said WAPI mobile terminal includes: a WAPI communication module and a processor module connected with each other, and a storage module connected with said processor module, and a dynamic cache module connected with said WAPI communication module and said processor module respectively. In such a configuration, the transistor’s gate-to-source capacitance can be applied to the corresponding delay stage output by closing the switch, for example, for lower-frequency operations. Each subsequent occurrence when the motion switch 20 is closed, will activate the program, powering the LED 22 in the repetitive flashing sequence.
