SIGHTING DEVICE Russian patent published in 2003 - IPC

FIELD: sighting devices of various objects, for example, of targets at firing. SUBSTANCE: the device has an operator's control panel, optical forming system, series-connected power supply source, luminance variation unit, adder, low-pass filter, sighting index illumination unit, unit of light filters and a sighting index forming unit, as well as a periodic signal generator with the unit of signals adjustment and a frequency transmitter. The offered device differs from the known ones by the fact that the device uses a screening unit, transmitter of the amplitude of periodic signals, indicators of their amplitude and frequency, the first and second control units, the input of the unit of the amplitude of periodic signals is connected to the output of the unit of adjustment of periodic signals, the first inputs of the indicators of the amplitude and frequency of periodic signals are connected to the outputs of the transmitters respectively of the amplitude and frequency of periodic signals, and the second inputs - to the outputs respectively of the first and second control units. The introduced elements provide for expansion of the device functional potentialities, in particular, in estimation of the condition of the operators, which makes it possible to timely take the respective measures both for correction of the actions fulfilled by them, and for their replacement. After two hours of continuous operation of the operators make it possible to reduce their efficiency by 15-17%. EFFECT: estimation of the influence of various environment conditions on the efficiency of operation of the operators. 1 dwg
