SIGHTING DEVICE Russian patent published in 2003 - IPC

FIELD: sighting devices of various obejcts, for example, targets at firing. SUBSTANCE: estimation of the condition of operators, which makes it possible to take the corresponding measures in due time both in correction of the actions carried out by them, and in their replacement. After 4 hours of continuous operation of the operators such measures make it possible to reduce the efficiency of their operation by 17-20%. Besides, provision is made for estimation of the influence of various external conditions on the efficiency of operation of the operators. The device has an operator's control panel, optical forming system, series-connected power supply, brightness variation unit, adder, low-frequency filter, sight index illumination unit, light filters unit and a sight index formation unit, as well as a generator of periodic signals with a unit for their adjustment and a frequency transducer. The offered device differs from the known ones by the fact that is uses a screening unit, transducers of the amplitude of periodic signals and time intervals, indicators of the amplitude and frequency of periodic signals and an indicator of intervals the first, second and third control units; the inputs of the transducers of the amplitude of periodic signals and time intervals are connected to the output of the periodic signals adjustment unit, the first inputs of the indicators of the amplitude and frequency of periodic signals, as well as of the intervals are connected to the outputs of the transducers of the amplitude and frequency of periodic signals, respectively, as well as of the time intervals, and the second inputs - to the outputs of the first, second and third control unit, respectively. EFFECT: expanded functional abilities of the device. 1 dwg
