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.

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.

An embodiment of the present disclosure discloses an eye protection structure for protecting a worker, the eye protection structure including a window convex outward to cover both eyes of the worker, wherein the window includes a transmissive portion, the transmissive portion includes an inner surface facing the worker's face and an outer surface opposite to the inner surface, a first radius of curvature of the outer surface of the transmissive portion and a second radius of curvature of the inner surface of the transmissive portion are different from each other, and a thickness of a central portion of the transmissive portion is greater than a thickness of an edge portion of the transmissive portion.

Described is an upper garment worn by welders while welding overhead, which is made of a breathable fabric and leather. The garment has a hood comprising leather attached to the neckline of the garment body, at least one leather sleeve, and leather on one shoulder and an upper front portion and an upper back portion of the garment that is contiguous with the at least one leather sleeve. The hood may be partially or completely made of leather, and the other sleeve may be leather. The strategic placement of leather on the garment improves the garment's durability, minimizes burns on the wearer from sparks and spatter, and protects the garment from the environment.

Provided is a powered air blower unit for delivering air flow to a user with constant air flow or varying speeds of air flow. The air blower unit may also include a filter for purifying the air.

A status alarm mask may include a main body to cover a face and eyes of a user. The mask may include a filter unit placed at a front surface portion of the main body to protect the eyes. The mask may include a communication module configured to establish a communication session with a welding torch held by the user and receive at least one inclination value of the welding torch being operated by the user, through the communication session. The mask may include a controller configured to determine whether a work of the torch is in progress, on the basis of an operation of the filter unit and to generate notification output data when the work of the torch is in progress. The mask may include an output unit placed at a location not overlapping with the filter unit and configured to receive and output the notification output data.

In some examples, a system (1900) includes a hearing protector (1920); at least one position sensor; at least one sound monitoring sensor; at least one computing device configured to: receive, from the at least one sound monitoring sensor and over a time duration, indications of sound levels to which a worker is exposed; determine, from the at least one position sensor and during the time duration, that the hearing protector is not positioned at one or more ears of the worker to attenuate the sound levels; and generate, in response to the determination that at least one of the sound levels satisfies an exposure threshold during the time duration and the hearing protector is not positioned at one or more ears of the worker to attenuate the sound levels, an indication for output.

In one aspect, a protective headwear is provided and includes a headgear, an outer shell, a duct and a manifold. The headgear is configured to engage a wearer's head and at least partially support the protective headwear on a wearer's head. The headgear includes a front, a rear opposite the front, a right side, and a left side opposite the right side. The outer shell is coupled to the headgear at a coupling location and includes a shield positioned to the front of the headgear. The duct is at least partially coupled to and at least partially positioned in an interior of the outer shell. The duct is located below the coupling location. The manifold is positioned to the rear of the headgear and configured to divert airflow into at least a first potion of airflow and a second portion of airflow

The present disclosure discloses a voice-controlled welding cap, which comprises a welding cap body, wherein the outer side of the welding cap body is provided with a mask, the inner side of the welding cap body is provided with a panel frame, a head ring, a connecting plate and an optical sensor, the inner side of the panel frame is provided with a main control chip and a language module input unit, and the language module input unit comprises a microphone, a voice chip and a peripheral resistance-capacitance device; the main control chip uses an STC8H 8BIT microprocessor control unit, the microphone is connected with the voice chip, and the voice chip, the mask and the optical sensor are all connected with the main control chip.

The present disclosure relates to an automatic darkening filter 20 which is suitable for darkening for protection from light, in particular from high intensity light, with a simplified set-up, as well as to a set-up device 40 for setting up parameters of a such filter 20. The present disclosure also relates to a system 100, 100 comprising such an automatic darkening filter 20 and such a set-up device 40, in particular a welding device 110. The present disclosure furthermore relates to a method for setting up such an automatic darkening filter 20 as well as to a headgear 10 with such an automatic darkening filter 20 and to a welding device 110 with such a set-up device 40.
