  • Patent number: 9109786
    Abstract: Using a control system for automatically switching power between a first light source attached to a welding shield pivotally mounted to an adjustable headband, and a second light source attached to the headband, a method for alternating power to the light sources includes steps (a) raising the shield to the uppermost rotational position resulting in power on to the second light source, the second light source remaining on at the raised position, and (b) lowering the welding shield to the maximum allowable distance resulting in power off to the second light source immediately followed by power on to the first light source, the first light source remaining on at the lowered position.
    Type: Grant

  • Patent number: 9033535
    Abstract: A control system for automatically switching power between two separate light sources integrated with a welding shield pivotally mounted to an adjustable headband includes at least one magnetic positional switch attached to the headband having electrical communication with at least one battery and the light sources, and two magnetic positional sensors strategically mounted on the interior surface of the welding shield along a defined arcurate path of rotation of the shield about the headband.

  • Patent number: 9010955
    Abstract: A lighting system retrofitted to a stock helmet with an interiorly fastened headband and a welding shield rotably mounted thereto includes a first light source mounted on an exterior surface of the welding shield, the welding shield adjustable to positions above and below the headband, a second light source mounted to the headband, a power source, a magnetic positional switching facility mounted on the exterior of the headband having electrical connection to the power source and the first and second light sources, a first positional sensor, and a second positional sensor, the first and second positional sensors mounted on the interior surface of the welding shield along an arcurate path defining the angular range of rotation of the welding shield relative to the magnetic positional switching facility.
