Abstract: Disclosed herein is an anti-glare device having a self-diagnostic mode capable of preventing an operation trouble by previously self-diagnosing a work environment and an operating condition, of enhancing work convenience by displaying a remaining battery charge, and of immediately executing a self-diagnostic mode by one-touch input. The anti-glare device includes an optical detection unit, an electromagnetic wave sensor unit, an electromagnetic wave detection unit, a control unit, a light transmission control unit, and a self-diagnostic command input unit for recognizing signals to check whether or not the device is operating normally, a shade level, a sensitivity level, a delay level, and a remaining battery charge by user's direct selection, operation, or adjustment, and inputting the recognized signals to the control unit.

Abstract: The present invention relates to sunglasses and goggles, and more particularly relates to a system for adjusting optical characteristics such as the color or the optical transmittance of sunglasses or goggles lens and relates to sunglasses and goggles equipped with the adjusting system. Provided is an optical characteristics adjusting system for sunglasses or goggles lenses, the system comprising: lenses equipped with an LCD panel; a lens drive unit equipped with an LCD drive unit for applying a driving voltage to the LCD panel; an illuminance detecting sensor for sensing the ambient illuminance; and a control unit for controlling the action of the lens drive unit in response to a signal from the illuminance detecting sensor. Also provided are sunglasses and goggles equipped with the optical characteristics adjusting system.

Abstract: 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.

Abstract: Disclosed is an information display and control device of a powered air purifying respirator wherein air flow of a blower device is electronically detected using a precision air flow sensor mounted to the blower device without using an air flow display device, and a graphic screen that displays an air flow level meter is displayed on the blower device or an additionally manufactured remote controller so that the air flow of the blower device can be checked during operation. The information display and control device includes a remote controller that is capable of allowing a worker to inspect an air flow state, to detect remaining battery power and expected use time, and to manipulate a blower device and exchanging information even in a state in which the worker wears the air purifying respirator and the blower device.
