METHOD FOR DETERMINATION OF CODE COMBINATION OF LOCK AND ITS UNLOCKING Russian patent published in 2013 - IPC E05B19/00 B21D53/42 

FIELD: construction.

SUBSTANCE: forces are determined on code elements with the help of an appropriate sensor, signals of these sensor are converted into a digital form, and by the value of the signal with the help of the appropriate dependence, previously introduced into the computer memory, the mode of the necessary control action at a bolt is found, and the drive providing for a load at a bolt is changed to this mode found by the computer, afterwards in series with the help of the same sensor, threshold forces are recorded on each element, signals of this sensor are converted into the digital form, at the same time position of code elements is determined with the help of the position sensor and with the help of the appropriate dependence previously introduced into the computer memory, the mode is found with the necessary control action at the code elements, and the drive providing for action at code elements is changed to this mode found by the computer, and with the help of the appropriate dependence previously input into the computer memory, parameters of the code combination of the lock are found, and the lock is opened.

EFFECT: improved reliability, accuracy in detection of a code combination of a lock and elimination of subjective factors, also during its unlocking.
