  • Patent number: 10821026
    Abstract: A welding protector (1) has a curved eye protection shield (10) with an electrically switchable light filter. The welding protector further has a magnifying cover (20) for arrangement on an eye facing inner side of the eye protection shield. The magnifying cover is pre-shaped based on a curve that extends equidistant to the curve the eye protection shield is based on. Further, the magnifying cover has two optical lenses (27) which in combination only partially cover the eye protection shield.
    Type: Grant

  • Publication number: 20190107749
    Abstract: An automatic-darkening filter 10, 10? that comprises a first polarizer 14, a second polarizer 18, a first liquid-crystal cell 16, and a sensor 64. The first polarizer 14 has a first polarization direction, and the second polarizer 18 has a second polarization direction. The liquid crystal cell 16 is disposed between the first and second polarizers 14, 18 and contains first and second optically-transparent, flexible, glass layers 40 and 42 with the liquid crystal layer 48 being located between these layers. The sensor 64 detects incident light and causes a signal to be sent, which causes molecular rotation within the liquid crystal layer. The inventive automatic-darkening filter is beneficial in that overall product weight can be reduced and the view field can be increased.
