Description
лени , отражающий тонус организма) визуально представл етс гладкой кривой (фиг. 2 А). Однако в этом сигнале присутствуют упом нутые быстрые изменени электрического сопротивлени , весьма малые по уровню в масштабах данной кривой.laziness, reflecting the body tone) is visually represented by a smooth curve (Fig. 2A). However, this signal contains the above mentioned rapid changes in electrical resistance, which are quite small in scale on a given curve.
С помощью активных фильтров с полосой пропускани 0,05-1 Гц можно выделить эти изменени и после соответствующего усилени получить сигнал фазической составл ющей ЭСК (фиг. 2 Б).With the help of active filters with a passband of 0.05-1 Hz, these changes can be distinguished and, after appropriate amplification, a signal of the ESC phase component is obtained (Fig. 2B).
Устройство работает следующим образом.The device works as follows.
Электроды 1 укрепл ют на теле человека. На выходе блока 2 выдел етс сигнал фазической составл ющей. Селектор 3 контролирует интервал между двум соседними фазическими импульсами. Причем наличие фазического импульса фиксируетс селектором 3 в том случае, если амплитуда этого импульса превышает некоторый заданный уровень а (фиг. 2 Б). Если указанный интервал больше установленной величины, то селектор 3 включает блок 4 сигнализации. Таким образом, во врем высокого уровн активности оператора с частым переключением внимани устройство не будет выдавать предупредительную команду, так как амплитуда импульсов больше , а интервал между ними меньше значений.Electrodes 1 are attached to the human body. At the output of block 2, the signal of the phasic component is extracted. The selector 3 controls the interval between two adjacent phasic pulses. Moreover, the presence of a phasic pulse is fixed by the selector 3 in the event that the amplitude of this pulse exceeds a certain predetermined level a (Fig. 2B). If the specified interval is greater than the set value, the selector 3 turns on the signaling unit 4. Thus, during a high level of operator activity with frequent switching of attention, the device will not issue a warning command, since the amplitude of the pulses is greater and the interval between them is less than the values.
фиксируемых селектором. В случае снижени уровн бодрствовани амплитуда фазических импульсов уменьшаетс , а интервал между ними возрастает и при достижении этими параметрами значений, фиксируемых амплитудно-временным селектором, последний воздействует на средства сигнализации.fixed by the selector. In case of a decrease in the level of wakefulness, the amplitude of the phasic pulses decreases, and the interval between them increases even when these parameters reach values fixed by the amplitude-time selector, the latter acts on the signaling means.
