Provided is a powered air blower unit for delivering air flow to a user with constant air flow or varying speeds of air flow. The air blower unit may also include a filter for purifying the air.

Provided is a welding information providing apparatus including a main body provided to be worn by a user, a display unit arranged on the main body and including a display for displaying a welding image to the user, at least one camera unit attached to an outer side of the main body and obtaining welding image frames with respect to a welding operation, and a processor configured to control the display to display the welding image generated based on the welding image frames, wherein the camera unit includes a darkening filter blocking welding light generated due to the welding operation.

The invention relates to a refractive surface for blocking short- and medium-wavelength visible-spectrum radiation that affects human physiology. The refractive surface selectively absorbs short wavelengths between 380 nm and 500 nm, between a maximum and a minimum absorption threshold, and selectively absorbs medium wavelengths between 500 nm and 590 nm, between a maximum and a minimum absorption threshold, the selective absorption of short and medium wavelengths between 380 nm and 590 nm not completely blocking the passage of visible light in this range. Other embodiments include an LED screen, a software product and an electronic device, and ophthalmic, intraocular or sunglass lenses.

A welding helmet camera system; the welding helmet camera system includes a welding helmet for covering a substantial portion of a head of a user-wearer during use and providing enhanced vision and protection for a user-wearer's eyes and face from flashes, sparks, extreme brightness and flying debris. The welding helmet includes a first-camera, a second-camera, a first-display screen, and a second-display screen. The first-display screen is in communication with the first-camera and is configured to broadcast digital video generated by the first-camera during a welding operation. The second-display screen positioned on the interior surface of the body and is in communication with the second-camera and is configured to display another digital video generated by the second-camera during the welding operation.

There is provided a welding helmet (1) comprising a face protection member (3) moveable between a lowered position in which the face protection member (3) covers a wearer's face, and an upraised position, in which the face protection member (3) uncovers the wearer's face, a headband suspension system (9) for fixing the face protection member (3) to a wearer's head, a protective cap (17) comprising a flexible outer layer (19) and at least one compressible inner liner (21).

A welding helmet includes at least one helmet shell, fixing elements, a glare shield device and at least one protective screen spaced therefrom, and at least one display device for presenting data in the field of view of a welder, the at least one display device being arranged in the edge region of the field of view in the intermediate space between the glare shield device and the protective screen. The glare shield device has at least one cut-out in the area of the at least one display device. Because there is no glare shield device in the region of the display device, the view of the display device is not impeded by the glare shield device.
