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.

Automatic darkening filters are often provided on a protective headgear, where protection from high intensity light is desired. An automatic darkening filter includes a switchable shutter, a shutter control system, a light sensor, and an imaging acquisition device. The switchable shutter is capable of assuming at least a dark state, a light state and an intermediate state.

An exposure-indicating supplied air respirator system comprises a head top, a clean air supply source and a portable personal communication hub. The head top comprises a visor that is sized to fit over at least a user's nose and mouth, a position sensor secured to the head top, and a head top communication module. The clean air supply source is connected to the head top that supplies clean air to the interior of the head top. The position sensor detects whether the visor is in a closed position or in an open position and the head top communication module communicates the visor position to the personal communication hub. If the personal communication hub receives a signal indicating the presence of a hazard, and if the visor is in an open position, an alert is generated.

In some examples, a system includes an article of personal protective equipment (PPE) comprising one or more sensors, the one or more sensors configured to generate usage data that is indicative of an operation of the article of PPE; and at least one computing device comprising a memory and one or more computer processors that: receive the usage data that is indicative of the operation of the article of PPE; apply the usage data to a safety learning model that predicts a likelihood of an occurrence of a safety event associated with the article of PPE based at least in part on previously generated usage data that corresponds to the safety event; and perform, based at least in part on predicting the likelihood of the occurrence of the safety event, at least one operation.

The electro-optical glare protection filter comprises 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 comprises 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, wherein both the first and the second electrode structure are present at the same laterally extended side of the volume. The first electrode structure may comprise a plurality of electrically separate electrodes and the second electrode structure may comprise a plurality of electrode lines.

A system including a head-mounted device having a face shield; a respirator coupled to or embodied in the head mounted device; a light having a light intensity; a light detector, and a computing device communicatively coupled to the at least one light detector that receive from the light detector data indicting a type and intensity of light, and determine that the light matches a particular type of light and whether it exceeds a threshold, and on the basis of this determination, modifies the intensity of the light.

In some examples, a system includes: a plurality of different articles of personal protection equipment (PPE) that are all controlled by a particular user, and a computing device. The computing device may include one or more computer processors configured to receive sets of data from each of the different articles of PPE, wherein each set of data is based at least in part on a type of each of the different articles of PPE; generate for display a user interface that contemporaneously includes a plurality of graphical elements that are based at least in part on at least two sets of data that correspond to at least two different articles of PPE of the plurality of different articles of PPE; and in response to receiving an indication of user input that corresponds to at least one of the plurality of graphical elements, perform at least one operation.

The present application discloses a wireless projector-type auto-darkening welding helmet comprising: a helmet housing; a headband structure for securing the helmet housing; an auto-darkening filter secured on the helmet housing; a wireless communication module; and a micro-projector which is data-connected to the auto-darkening filter and the wireless communication module, wherein when the auto-darkening filter is in a transparent state, the micro-projector is adaptable to project operating parameters of the auto-darkening filter and/or data received by the wireless communication module, as images, onto a plane in front of the welding helmet such that they can be watched by an operator who wears the welding helmet on his/her head. The present application also discloses a welding apparatus equipped with said wireless projector-type auto-darkening welding helmet.

The present application relates to a welding helmet comprising a helmet housing and a head cover adapted to be worn on a wearer's head and made of an air-impermeable and flexible material, wherein a zipper arrangement is provided between the helmet housing and the head cover to detachably connect the head cover to the helmet housing around the whole perimeter of an opening of the helmet housing, and wherein after the head cover is connected to the helmet housing, the zipper arrangement is located within the housing of the welding helmet. The present application also relates to an assembly having the welding helmet.

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.
