TOMSK, Feb 17 –
RIA Tomsk. Scientists of Tomsk State University of Control Systems and Radioelectronics (TUSUR) figured out
how to use meander lines used on printed circuit boards to protect electronics
from the "harmful" pulses; development will be useful for the protection
and security systems of banks, space equipment, told RIA Tomsk one of the
developers Alexander Nosov.
According to him, meander line of a delay in itself –
is not a find, they are used on printed circuit boards for synchronization of
signals. However, TUSUR scientists have for the first time suggested to apply
them to protection of the critical radio-electronic equipment to which it is
possible to carry, for example, "hardware" of a banking system of

"There was an incident when terrorists managed to
disable the bank's alarm at distance using devices manufactured in amateurish
conditions, – using a short impulse having a short duration, but huge
amplitude. Our line can display this impulse on the sequence of impulses of
smaller amplitude that doesn't allow to put the key equipment out of
action", – the scientist told.
According to the scientist, the same lines, but in
other configurations, can be used also for protection against the electrostatic
category of the expensive radio-electronic equipment used in spacecrafts.
"If to put our device on an entrance in radio-electronic equipment or in
it critical knots, it will also display an interfering impulse, preventing
equipment malfunction", – Nosov explained.
He noted that the Tomsk development has no analogs,
scientists have already received four patents for its application. Now they
continue research work and are actively engaged in commercialization of the
