INFORMATION CONTROL SYSTEM Russian patent published in 2010 - IPC F42B15/01 

FIELD: instrument making.

SUBSTANCE: proposed system comprises operator control board, optical shaping system, power supply, brightness control unit, adder, LF filter, hairline mark illumination unit, light filters unit and hairline mark shaping unit, and periodic signal generator incorporating periodic signal adjustment module and frequency transducer. Proposed system additionally comprises data and control unit, periodic signal amplitude transducer, periodic signal amplitude and frequency indicators, first and second control units. Note here that periodic signal amplitude transducer input is connected with output of periodic signal adjustment unit. First inputs of periodic signal amplitude and frequency indicators are connected with outputs of periodic signal amplitude and frequency indicators, while second inputs are connected with outputs of first and second control units. Input of periodic signal amplitude transducer is connected with output of periodic signal adjustment unit. First inputs of periodic signal amplitude and frequency indicators are connected with outputs of periodic signal amplitude and frequency transducers, while second inputs are connected with outputs of first and second control units, respectively.

EFFECT: higher efficiency of operation.
