Latest Patents

Frederick P Edgar holds a patent for a "Replaceable, self-contained expanded viewing light shield cartridge for welding helmet." This electronic quick-change cartridge is designed for use in welding helmets. The cartridge base is constructed from optically dense polycarbonate or similar materials, which serve as a passive filter to provide essential eye protection during welding operations. A port in the base accommodates a variable density LCD cell, while a cavity within the base houses the electronics necessary for driving the cell. Optical masks are incorporated to prevent light leakage through any interfaces of the structure. Under low light conditions, the welder can view the workpiece through a nearly transparent or slightly opaque LCD cell. When an arc is struck, the LCD cell darkens to a shade that corresponds with the surrounding polycarbonate material. This innovative design allows welders to have an expanded viewing area during the actual welding operation, significantly improving their ability to work safely and effectively.
