|20110251838||METHOD FOR DISPLAYING INFORMATION IN MULTIPLE LANGUAGES ON WELDING HELMET CARTRIDGE - A method for displaying information in multiple languages on a welding helmet cartridge is provided, which not only shields a worker's face from light generated when the worker performs a task such as welding or cutting but also automatically performs shade level adjustment and work time setting functions for each task and also allows information such as an operating status to be displayed in multiple languages. In the method, a work time during which the LCD screen of the cartridge is darkened is calculated and the calculated work time is stored in the memory and the stored work time is displayed on the display unit when entering a life mode entrance step. Data of an operating state in multiple preset languages is stored in the memory and data of the operating state in a desired language, which is selected from among the multiple languages, is displayed on the display unit.||10-13-2011|
|20110010815||WELDING HELMET INCLUDING ANTI-BLINDING DEVICE TO SELECTIVELY AND CONVENIENTLY CONTROL WELDING OPERATION AND GRINDING OPERATION - Disclosed is a welding helmet including an anti-blinding device to selectively control a welding operation and a grinding operation, and more particularly, a welding helmet, which stably protects the welder's eyes and enables easy switching of the anti-blinding device from a welding operation mode to a grinding operation mode or vice versa without taking off the welding helmet. In addition to the anti-blinding device to protect the welder's eyes from light emitted from a welding or cutting torch during a welding or grinding operation, a switch is provided at an outer surface of the welding helmet to allow a welder to conveniently select a welding operation mode or a grinding operation mode without taking off the welding helmet.||01-20-2011|
|20100132086||WELDING MASK THAT CAN CONTROL LCD SHIELDING GOGGLE WITHOUT TAKING OFF - Disclosed is a welding mask that enables a user to easily and conveniently perform manipulation thereof, thereby protecting the user's eyes and face. The welding mask includes a welding face to cover the user's face, the welding face having a transparent window, a wearing band to be worn on the user's hair, the wearing band being coupled to the welding face such that the welding face is rotated upward/downward, a liquid crystal display (LCD) shielding goggle including an LCD panel mounted at the rear of the transparent window of the welding face to protect the user's eyes from strong injurious light rays generated during welding, and a manipulation unit disposed spaced apart from the lower end of the LCD shielding goggle, the manipulation unit serving to detect injurious light rays generated during welding and operate the LCD panel accordingly.||06-03-2010|
|20100090997||FUNCTIONAL DISPLAY TYPE ANTI-BLINDING DEVICE - Disclosed is a functional display type anti-blinding device having an anti-blinding plate for indication and control of a screen display condition and variation in light transmittance. The anti-blinding plate includes a filter to selectively filter light, a polarizer to polarize the filtered light, a shutter LCD having a variable light transmittance based on control of a light transmission control unit, a transparent dot-matrix LCD to indicate the screen display condition based on control of a display control unit, and a glass protector at the rear of the transparent dot-matrix LCD. The shutter LCD flickers several times to indicate an initial state and is turned off. The transparent dot-matrix LCD is turned on upon turn-off of the shutter LCD to indicate the screen display condition. The shutter LCD is turned on upon turn-off of the transparent dot-matrix LCD to transmit light based on preset light transmittance.||04-15-2010|
|20100007938||DIGITAL TYPE ANTI-GLARE DEVICE USING TOUCH AND METHOD OF CONTROLLING THE SAME - Disclosed is a digital type anti-glare device capable of conveniently performing input, operation and adjustment, and a method of controlling the same. The digital type anti-glare device includes 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. Accordingly, it is possible to prevent operation failure due to switch contact, dust or humidity or the like by a touch sensor and encoder input and to facilitate input, operation and adjustment even in a state in which an operator wears gloves.||01-14-2010|
