A welding protection device (10) comprises a shield body (12), an automatic darkening filter (13) insertable in the shield body, and a haptic sensing unit to sense a touch pattern occurring on at least a first portion of the shield body or automatic darkening filter assembly. Upon sensing of a touch pattern, a user definable command is executed. This user definable command can place the welding protection device in a specific operational state.

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 wristwatch 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.

According to an embodiment of the present disclosure, provided is a welding protector including a head band including a band main body including a front support portion for supporting forehead of a user, a rear band portion arranged opposite to the band main body, and a support band portion connected to the front support portion and supporting an upper portion of the user's head, a face shield rotatably connected to the head band and protecting face of the user, and an auxiliary shield protecting a part of the user's head, wherein the auxiliary shield and the head band are connected to each other.

System has an optical sensor (1), an aperture with the optical element (2) with the changeable permeability and an activation light (3) emitting radiation, which is detected by the optical sensor (1). The activation light is connected with the switch (4) and it is placed within the reach of the optical sensor (1). Within a device which realizes the technological process with the luminous manifestation the instruction for the beginning of a given technological process is detected and on the basis of this instruction the activation light (3) lights up. This activates the optical sensor (1) by means of the activation light (3) before the optical sensor (1) detects the luminous manifestation of the technological process itself. The activation light (3) can be a simple infrared LED diode. The advantage lies in the fact that the protective device itself does not have to be modified in any way and its reaction time can be shortened to zero, or negative reaction time can be achieved since we use time passing during the initiation of the technological process before the appearance of the luminous manifestation for the darkening.

A cushion pad for head bands, installed at the rear part of a head band worn on a worker's head so as to support the back of the worker's head while adjusting the length of the head band. The cushion pad includes a pad unit having a concave spherical-shaped surface closely adhered to the back of the worker's head and provided with a first prop and second props to support the upper central region and both lower side regions of the back of the worker's head, and an adjustment unit formed at the rear of the center of the pad unit and provided with through holes formed at both sides thereof to receive both rear ends of the head band and a rotary lever between the through holes to pressurize and fix the head band, thus allowing a worker to more conveniently and stably wear a welding mask.

A face shield assembly for use with a hard hat to protect a user from injury caused by an arc-flash event. Ventilation slots are provided at the sides of the assembly below an apparatus used for connecting the face shield assembly to a hard hat. Alternatively, lower front ventilation slots are provided, which also improve voice communication by the user. The face shield assembly can have either side or front ventilation slots, or both.
