A multi-try counter-meshing gears (CMG) discrimination device based on micro electromechani-cal system (MEMS) technology was designed for some specified information fields. The discrimination deviceconsists of two groups of metal CMG, two pawl/ratchet mechanisms, two driving micromotors and two re-setting micromotors, which make the CMG withdraw by raising the pawls. The energy-coupling element isa photoelectric sensor with a circular plate which is notched. Micromotor is fabricated using the ultravioletLiGA (UV-LiGA) fabrication process and precision mechanical engineering. The discrimination device has thefunction which can automatically reset, with the correct resetting code, it can be tried another times. 相似文献

This paper proposed a new method to generate the complete sets of unique signals.It contains sequences comparing,improved exhaustive searches and ranking method.Characters of this new method are complete set;higher effective;independent of certain mathematical constraints.And also some 24 bi-valued events sets generated by this method were discussed and these set are now used in our high consequence system. 相似文献
