Helmet with visor having a shell structure shaped is to at least partly cover the user's head. The visor is hinged to the opposite sides of the shell and mobile with respect to the shell between a raised position and a lowered position where it provides a protective extension of the helmet at the eyes of the user. The visor is manually switchable from the raised and lowered positions by using a magnetic coupling between the visor and the shell which guides and keeps the visor stable in the raised and lowered position and in a plurality of intermediate positions.

A curved eye protection shield for welding protection. The eye protection shield has an electrically switchable darkening filter and a protective cover. The darkening filter has eye facing major inner and outer surfaces, and the protective cover has major inner and outer surfaces. The protective cover is provided for arrangement on the inner surface of the darkening filter. The inner and outer surface of the darkening filter are equidistant, whereas the inner and outer surface of the protective cover are non-equidistant. The invention is advantageous in that it provides an eye protection shield having a minimized refractive power.

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.

A tool communication adapter system is provided. One exemplary system described herein includes a tool communication adapter having an adapter body including first and second mechanical attachment ends, a first electrical connector proximate the first mechanical attachment end and a second electrical connector proximate the second mechanical attachment end, a first supply channel having an opening extending through the body between the first and second mechanical attachment ends, and including a first supply channel connector at the first attachment end and a second supply channel connector at the second mechanical attachment end, and a control unit in communication with the first and second electrical connectors. The control unit is configured to provide a filter command signal to a protective filter in response to a signal received at the first electrical connector. An exemplary tool communication adapter thus allows communication between a tool and personal protective equipment.

An example head-worn device includes a camera, a display device, weld detection circuitry, and pixel data processing circuitry. The camera generates first pixel data from a field of view of the head-worn device. The display device displays second pixel data to a wearer of the head-worn device based on the first pixel data captured by the camera. The weld detection circuitry determines whether a welding arc is present and generates a control signal indicating a result of the determination. The pixel data processing circuitry processes the first pixel data captured by the camera to generate the second pixel data for display on the display device, where a mode of operation of said pixel data processing circuitry is selected from a plurality of modes based on said control signal.
