Patent ID: 8049151

Claim:
A digital type anti-glare device using touch comprising: an optical detecting unit detecting light generated by a welding or cutting torch; an electromagnetic wave sensing unit sensing electromagnetic waves generated by the welding or cutting torch; an electromagnetic wave detecting unit comparing a resonated signal received from the electromagnetic wave sensing unit with a variably set reference value, when an electromagnetic wave detecting unit start-up signal is applied; a control unit applying the electromagnetic wave detecting unit start-up signal to the electromagnetic detecting unit and monitoring a variation in electromagnetic wave signal received from the output of the electromagnetic wave detecting unit, when light detection is started by the optical detecting unit; a light transmission control unit controlling a variation in light transmissivity of an anti-glare plate according to an output signal of the control unit; a touch sensor input unit recognizing a shade degree and a grind mode level by direct selective operation or adjustment of a user as a digital contact signal and inputting the shade degree and the grind model level to the control unit; and an encoder switch input unit recognizing a sensitivity level and an opening delay level by the selective operation or adjustment of the user and inputting the sensitivity level and the opening delay level to the control unit.
