A system for aiding a user in at least one of welding, cutting, joining, and cladding operations is provided. The system includes a welding tool and a welding helmet with a face-mounted display. The system also includes a spatial tracker configured to track the welding helmet and the welding tool in 3-D space relative to an object to be worked on. A processor based subsystem is configured to generate virtual objects based on objects found in a welding environment and transmit the virtual objects to a predetermined location on the face-mounted display.

Provided is a light attached to a helmet where the light does not move when a face shield of the helmet is rotated up or down.

A welding hood for protecting an operator's face comprising a face protective shield having a concave rearward side for receiving the operator's face, a viewing opening extending through the shield, wherein the viewing opening is located in a position in front of the eyes of the operator while the hood is fixed to the operator's head. The welding hood includes an eye box located adjacent the viewing opening. The eye box has walls framing the viewing opening and extend inwardly from the rearward side of the shield. The walls are configured for blocking reflective arc flashes and/or light from entering the operator's field of view during welding. The welding hood has sidewalls of varying width and a neck attachment for added protection. The welding hood also includes a lens located within the viewing opening and at least one strap for securing the welding hood to the operator's head.

A welding helmet can record a welding time based on an arc intensity detected by a sensor mounted on the helmet. A configured level is compared with the arc intensity detected by the sensor to determine a welding duration. Individual welding times from multiple welding instances can be accumulated over a period of time to provide a total welding time for an operator. The total welding time may be stored in the welding helmet.

Protective headgear with a curved switchable shutter and curved front and rear cover plates and including at least two antireflective layers.

Curved, arcuately-bonded liquid-crystal cells that include substrates held together by an edge adhesive cured after the substrates were bent into a congruently curved configuration; methods of making such cells; and, switchable shutters and automatic darkening filters that include such cells.

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.

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.
