The present disclosure relates to darkening filters 10, 10 which are suitable for selectively darkening an optically transmissive window 20 for protection from light, in particular from high intensity light. The darkening filter 10, 10 is mounted in a forward-facing optically transmissive window 20 and comprises a non-uniform pattern 30 of switchable shutters 32 capable of being switching to at least a dark state and a light state by a shutter control system 40. The present disclosure also relates to a method of operating such darkening filters 10, 10. The present disclosure furthermore relates to vision-protective headgears 100, 100, welding shields 110 and panes 120 comprising the darkening filters 10, 10 according to the present disclosure.

A welding helmet for detecting arc data is provided. One embodiment of the welding helmet includes an arc detection system configured to detect one or more welding arcs that occur during one or more welding operations. The welding helmet also includes control circuitry configured to count a number of the one or more welding arcs detected by the arc detection system. The welding helmet includes a storage device configured to store the number of the one or more welding arcs.

A personal powered air respirator, for example a welding or spraying helmet (10), includes a remote controller (30) for adjusting one or more operating parameters of the helmet and a means of displaying information regarding said parameter in, on or adjacent the interior of the vision panel (12) of the helmet. The invention allows for convenient adjustment in use. The remote controller is adapted to clothing, such as belt, glove or pocket, or may be incorporated in equipment for use with the helmet.

A welding helmet with a sensor-operated light and photochromic visor lens including a welding helmet body configured, sized, and shaped to cover and substantially conform to a welder's forehead. A frustoconical protrusion, integrated into a front side of the welding helmet body, houses a battery-operated LED light bulb. At least one photosensor is disposed proximal the protrusion. Upon the detection of a welding arc by the at least one photosensor, an auto-darkening filtered visor lens darkens and the LED light bulb in activated. A battery compartment, an on-off switch, and a microchip are disposed on a rear side of the welding helmet body. A padded length-adjustable strap is pivotally disposed across the rear side of the welding helmet body.

A welder protection device comprising a shell and a transparent front cover for protection of a wearer of the welder protection device, and an auto-darkening optical filter. The welder protection device further comprises a retracting mechanism arranged to move the optical filter optical filter from an active position to a retracted position and vice versa. In the active position, the optical filter lies inside the welder protection device and in the wearer's field of view, and in the retracted position the optical filter lies inside the welder protection device and outside the wearer's field of view.

A welding information providing device is proposed. The device may include a body provided to cover at least a portion of a worker' face and including a first region facing the worker' face and a second region located in a region opposite to the first region. The device may also include a camera unit located in the second region of the body and capturing a welding video to acquire a video frame. The device may further include a display unit located in the first region of the body and providing a video generated through the video frame.

The present invention discloses an auto darkening mask which comprises a weld cap and a filter mechanism, wherein the filter mechanism includes a lens module, a connecting line and a regulating system; and the weld cap is provided with a visible window. The lens module is assembled inside the weld cap and is opposite to the visible window of the weld cap. The regulating system is located at the outside of the weld cap and connected with the weld cap, and the lens module is connected with and controlled by the regulating system through the connecting line. The auto darkening mask is very convenient to regulate and saves labor.

A welding helmet for detecting arc data is provided. One embodiment of the welding helmet includes an arc detection system configured to detect one or more welding arcs that occur during one or more welding operations. The welding helmet also includes control circuitry configured to count a number of the one or more welding arcs detected by the arc detection system. The welding helmet includes a storage device configured to store the number of the one or more welding arcs.

Described herein are examples of smart helmet modules that can be affixed to conventional welding helmets. In some examples, a smart helmet module may include one or more sensors configured to detect if/when welding is occurring, and/or whether a welding helmet is being worn in an up or down position, or not at all. In some examples, a smart helmet module may include one or more helmet devices configured to automatically activate or deactivate based on whether welding is taking place and/or the welding helmet is being worn up, down, or not at all.
