Abstract: Anisotropic film laminates for use in image-preserving reflectors such as rearview automotive mirror assemblies, and related methods of fabrication. A film may comprise an anisotropic layer such as a light-polarizing layer and other functional layers. The film having controlled water content is heated under omnidirectional pressure and vacuum to a temperature substantially equal to or above a lower limit of a glass-transition temperature range of the film so as to be laminated to a substrate. The laminate is configured as part of a mirror structure so as to increase contrast of light produced by a light source positioned behind the mirror structure and transmitted through the mirror structure towards a viewer. The mirror structure is devoid of any extended distortion and is characterized by SW and LW values less than 3, more preferably less than 2, and most preferably less than 1.

Abstract: An auto darkening mask which has a weld cap and a filter mechanism, wherein the filter mechanism includes a lens module, a connecting line and a regulating system; and the weld cap is provided with a visible window. The lens module is assembled inside the weld cap and is opposite to the visible window of the weld cap. The regulating system protrudes out of an outer side of the weld cap and is connected with the weld cap, and the lens module is connected with and controlled by the regulating system through the connecting line.

Abstract: A 3D image display device includes: a liquid crystal (LC) display panel including, a first array substrate (AS) including a gate line (GL) extending in a first direction (FD), a data line (DL) extending in a second direction (SD) substantially perpendicular to the FD, and a pixel electrode (PE) connected to the GL and the DL and having first branch electrode portions (FBEPs) having a first width, each of the FBEPs being spaced from each other by a first interval substantially ?the first width, and a LC lens panel including a second AS including lens electrodes (LEs) extending in a third direction (TD) tilted with respect to the SD by a first angle having an absolute value ?about 5° and ?about 15°. Each of the FBEPs extends in a fourth direction having a first tilting angle with respect to the TD by about 45° or about 135°.

Abstract: A grinding mode selector switch for welding masks which controls an anti-glare device blocking hazardous light during a welding operation or an operation using a cutting torch and protecting eyes of a worker during a grinding operation without taking off a welding mask during the welding operation and the grinding operation is disclosed. The grinding mode selector switch for welding masks is installed on the outer surface of the welding mask and is not touched by an external object, and the protruding height of a button protective cap is equal to or greater than the height of a button so as to prevent the button from being touched by an external object when the worker performs an operation.

Abstract: Disclosed is a welding helmet with a protection cover for a cartridge, being manufactured in various forms and capable of covering a cartridge of the welding helmet and thereby protecting the cartridge from welding heat and preventing melting of the cartridge. According to the present invention, the welding helmet comprising a helmet body covering an operator's face, an opening formed on a front of the helmet body, and a cartridge connected with the opening and equipped with an LCD panel which intercepts light emanating from a welding operation to protect the operator's eyes, further comprises a heat transmission interception unit formed on a front of the cartridge of the welding helmet to prevent surface deformation caused by welding heat.

Abstract: A face plate has a major chamber positionable in front of a face of a welder. A visor housing has a forward opening. A minor chamber is provided within the visor housing. A forward assembly is fixedly positioned within the minor chamber adjacent to the forward opening. The forward assembly has a glass ultraviolet filter centrally. The forward assembly has a heat resistant transparent plate outwardly. The forward assembly has a fixed polarized filter lens inwardly. A rearward assembly is fixedly positioned within the major chamber adjacent to the visor housing. The rearward assembly includes a rotatable polarized filter lens. A drive assembly is adapted to rotate the rotatable polarized filter lens with respect to the fixed polarized filter lens.

Abstract: A welding mask including a mask body for covering an entire face of a wearer having an opening portion corresponding to eyes of the wearer thereof; a rotatable cover rotationally coupled to a front of the mask body upward and downward; a shading filter mounted on the rotatable cover so as to shade a light generated during welding operation thereof; an elastic coupling means for rotationally coupling the rotatable cover to both side surfaces of the mask body upward; and a fixing means for fixing the rotatable cover or releasing a fixing status thereof formed at one side of the mask body. In addition, a window is further formed at the rear portion of the rotatable cover having the shading filter, thereby improving operation efficiency.
