The key and metal plate both need to vibrate at exactly same frequency. Once key is inserted in metal plate, and once the frequencies of key and metal plate match, then an OK signal is given out allowing the same key to access the lock.
Should there be a mismatch of frequencies of key and metal plate, then an alarm will be given out to the Security Personnel or Remote Security system, alerting them of security breach. Once such alert has been issued, then the individual cannot access the lock, thereby preventing any further potential to breach security.
Matching the resonance frequencies of vibrations of 2 objects/parameters. E.g. If a ‘lock’ is to be opened by its own ‘key’, the lock can be kept ‘vibrating’ at very high frequency with a small displacement. So, if you want to insert its ‘key’ & open the lock, you got to vibrate the ‘key’ with exactly the same frequency as that of the lock while inserting it in the lock. If the frequencies of both key and lock are exactly the same equal, then:
Relative frequency between the lock and key will be Zero, as both are vibrating in phase and at same frequency.
If the frequency of the key does not match to even a slight order, the lock will not open as the frequency of lock is not equal to the frequency of key so, the key would not fit in properly.
Thus, it can be used for security in banks where a ‘vibrating’ plate can be placed before the lock. In such case, the lock would not be required to vibrate.
If the frequency of plate and frequency of key match, a signal can be given to stop the plate from vibrating and thus the lock is ready to ‘accept’ the key.
If the frequencies mismatch to the slightest order, an alarm can be given to signify ‘unauthorized access’. The vibrations may be along X, Y or Z axis.
This effect of matching the frequency may be used in other electrical, electronic or Computer systems (where highly confidential data/objects lie protected).
The effect of ‘Magneto-Striction’ in case of metals can be thought of, as we observe displacement in 3-dimensions in the body of the metal.
