Popis:	A multi-try counter-meshing gears stronglink based on micro electromechanical system (MEMS) technology is introduced, including research, design, couple and fabrication of unique signal (UQS) for some specified fields of information security. The stronglink consists of two groups of metal counter-meshing gears, two pawl/ratchet mechanisms, two driving micromotors and two resetting micromotors. The resetting micromotors make counter-meshing gears withdraw by raising pawls so that the interfered counter-meshing gears will be relieved. The energy-coupling element is a photoelectric sensor with a circular notched plate. The counter-meshing mechanism is fabricated using the ultraviolet-lithographie, galvanoformung and abformung (UV-LiGA) process and a precision mechanical technique. The stronglink can be tried several times if the correct resetting code is known.
