Embodiments of systems and methods for wireless live video streaming from a welding helmet are disclosed. In one embodiment, a welding helmet includes an auto-darkening filter having an inner surface. The welding helmet also includes a camera positioned next to the inner surface of the auto-darkening filter at a location between two eyes of a user of the welding helmet, without obstructing a view of the user through the auto-darkening filter. The camera is configured to generate image information in real time corresponding to a field-of-view through the auto-darkening filter during a welding process. The welding helmet further includes a video streaming device operatively connected to the camera and configured to receive the image information from the camera and transmit the image information as real time live streaming video in a wireless radio frequency transmission.

In one aspect, a split forehead strap of headgear is provided. In one aspect, a headgear for engaging and supporting protective headwear on a wearer's head is provided. The headgear includes a first side member on a first side of the headgear, a second side member on a second side of the headgear, and a forehead strap coupled to and extending between the first and second side members. The forehead strap is configured to engage a wearer's forehead with the headgear worn by a wearer. The forehead strap includes an upper member and a lower member spaced-apart from the upper member along at least a portion of the lower member to provide a cavity between the upper and lower member. In one aspect, a protective headwear is provided and includes a forehead strap defining a longitudinally extending cavity that alters in thickness.

The electro-optical glare protection filter includes a liquid crystal cell, which is a laterally extended liquid crystal cell defining a volume between two laterally extended sides. The volume containing liquid crystals and having, in a vertical direction perpendicular to lateral directions, a thickness being smaller than an extension of the volume in any lateral direction. The FFS cell includes a first electrode structure and a second electrode structure, which are arranged to change an orientation of the liquid crystals in the volume when a voltage is applied between them. Both the first and the second electrode structure are present at the same laterally extended side of the volume. The first electrode structure may include a plurality of electrically separate electrodes, and the second electrode structure may include a plurality of electrode lines.

Provided is a welding helmet control device comprising: a welding sensor or a light sensor configured to detect presence and intensity of welding light; a controller configured to count presence, intensity, and elapsed time of welding light, detected by the welding sensor or the light sensor, and to determine welding intensity, weld time, resting time, and weld number; a memory configured to store the welding intensity, the weld time, the resting time, and the weld number; a display configured to display the welding intensity, the weld time, the resting time, and the weld number, stored in the memory; a shutter driver configured to drive a shutter liquid crystal display (LCD) to vary a darkness concentration under control of the controller; and a setting unit configured to receive a setting value and a manipulation command, set by a user, and to transmit the received information to the controller.

Eyewear is provided including a frame, and a camera connected with the frame, in which the camera is configured to be controlled by a remote controller. The camera may be configured to capture video and/or a photo. The eyewear may include data storage, and the camera may be connected to the data storage. A wrist watch may be configured to act both as a time piece and a controller of the camera. The eyewear may also include a heads up display and/or a video file player. The eyewear may also include an electro-active lens.

Head worn devices having a variable shade component and a fixed shade component, and methods of operation, are disclosed. An example head worn device includes an auto-darkening lens configured to adjust a shade value within a first shade value range, a second lens having a fixed shade value greater than 0, the auto-darkening lens and the second lens overlapping in a field of view of the head worn device to result in a net shade value range in the field of view that is greater than the first shade value range, and a clear lens on an exterior of the auto-darkening lens and the second lens.

An illuminated welding helmet system for selectively illuminating a darkened area during welding operations includes a welding helmet that may be worn during welding and the welding helmet includes an auto lens. A light unit is coupled to the welding helmet and the light unit selectively emits light outwardly from the welding helmet thereby facilitating a darkened area to be visible. The light unit is in electrical communication with the auto lens. Moreover, the light unit is turned on when the auto lens does not detect light and the light unit is turned off when the auto lens detects light.

In one aspect, a headgear for engaging and supporting protective headwear on a wearer's head is provided. The headgear includes a first side member positioned on a first side of the headgear, a second side member positioned on a second side of the headgear opposite the first side, a forehead strap coupled to the first and second side members and positioned on a front half of the headgear, and an occipital strap having an end coupled to one of the first side member and the second side member on the front half of the headgear and the occipital strap extending to a rear half of the headgear.
