Provided is a welding helmet control device comprising: a welding sensor or a light sensor configured to detect presence and intensity of welding light; a controller configured to count presence, intensity, and elapsed time of welding light, detected by the welding sensor or the light sensor, and to determine welding intensity, weld time, resting time, and weld number; a memory configured to store the welding intensity, the weld time, the resting time, and the weld number; a display configured to display the welding intensity, the weld time, the resting time, and the weld number, stored in the memory; a shutter driver configured to drive a shutter liquid crystal display (LCD) to vary a darkness concentration under control of the controller; and a setting unit configured to receive a setting value and a manipulation command, set by a user, and to transmit the received information to the controller.

A welding hood for protecting an operator's face comprising a face protective shield having a rearward side configured for receiving the operator's face and a viewing opening extending through the shield. The viewing opening is located in front of the eyes of the operator while the hood is fixed to the operator's head. An eye box is located adjacent the viewing opening and extends inwardly from the rearward side of the shield to block reflective arc flashes, sunlight, and/or shop-lighting from entering the operator's field of view during welding. The welding hood includes a light mounted to the face protective shield for shining light outward from a front side of the face protective shield, a cooling fan mounted adjacent the rearward side of the shield, and a clear protective member mounted within the eye box and adjacent the operator's eyes.

An eyewear system including an eyewear frame and an application module. The eyewear frame including a docking station, and an electronic connector including a first set of preconfigured application connection points. The application module adapted to be mounted to the docking station, and including an electronic device configured to perform a function, and a second set of preconfigured application connection points corresponding to at least some of the first set of preconfigured application connection points. The second set of preconfigured application connection points including at least two different sub-function connections used to support the function of the electronic 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.

A method is disclosed, comprising obtaining at least one metric of an eye; and determining, based on the at least one metric of the eye, at least one parameter for manufacturing an ophthalmic shield to be worn on the eye. In some embodiments, the ophthalmic shield may have a minimum horizontal dimension of 18 mm and a minimum vertical dimension of 15 mm. In some embodiments, the ophthalmic shield may have a minimum horizontal dimension of 20 mm and a minimum vertical dimension of 17 mm. In some embodiments, the ophthalmic shield may have a minimum horizontal dimension of 26 mm and a minimum vertical dimension of 22 mm.

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.

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.

A flip-to-wear eye shield system is provided. By integrating a hinge into elements of the frame and/or the lens, the eye shield can be manufactured and assembled more quickly and with less costs. In an embodiment, a lens may click (or snap) onto molded posts of a frame in a substantially flat position. An integrated living hinge in the frame may bend to allow the lens to flip downwards toward the frame to a second position for use. The posts may also click (or snap) into place in an underside of the frames. In another embodiment, a lens may click (or snap) onto molded posts of a flame in a substantially flat position. An integrated living hinge, formed by notches in the lens, may allow the lens to bend to flip downwards to the frame to a second position for use. A dispenser allows storing the eye shields in the flat position and dispensing in the second position for use.

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.
