摘要: A lock system has an elongated key provided with a plurality of permanent magnets spaced axially and angularly apart along the in predetermined magnet array. cylinder having no moving parts defines passage generally complementary to this magnetic-field detectors at least some which are arrayed be line when it is inserted into passage. An electronic circuit connected these electrically operable latch programmed open those that change state manner indicating they juxtaposed respective magnets, but not one or more out array similarly subjected magnetic field.
