Based on a study of the running condition of physical code mechanism, VMCM＇s configuration, ternary encoding method, running action and logic are derived. The cases of multi-level code mechanism are designed and verified with the VMCM method, showing that the presented method is effective.展开更多

Instead of using mechanical springs, permanent magnetic locks feature alternating and equidifferent mono and multiple magnetic codes. The locks contain millions of codes. With no key hole or gears, permanent magnetic locks cannot be opened by a master key. The locks are damage proof, shock proof and drill proof, and easy to use. Permanent magnetic locks are used for safes, cars, motorcycles and bicycles.展开更多
