An ocular shield for facilitating generation of Visual Evoked Potentials (VEP) is disclosed. The ocular shield may include a body configured to be disposed over an ocular globe of an eye. Further, the body may include an interior surface and an exterior surface. Further, the ocular shield may include at least one light source configured to generate at least one light emission. Further, the at least one light source may be coupled to the body to facilitate transmission of the at least light emission from the interior surface of the body. Further, the ocular shield may include a power source, electrically coupled to the at least one light source, configured to provide electrical energy to the at least one light source. Further, the ocular shield may include a controller configured to control the power source. Further, the controller may be electrically coupled to the power source.

A mechanical refrigeration and heating unit supplies filtered air that is heated or chilled as needed for one or more welding helmets. A portable or transportable cabinet or housing has an air inlet on which a cartridge air filter is mounted. The air passes through an evaporator coil into an evaporator plenum where an evaporator fan moves the air to an outlet that connects with a heater plenum that contains an electric heater module. An outlet of the heater if fitted with an outlet port to which an air hose may be connected. A compressor, condenser coil, receiver, and condenser fan are located in an equipment compartment in the housing. A control board in the unit allows the user to select heated or chilled air. A clogged-filter alarm provides visual and audio alarm signals when pressure in the evaporator plenum falls below a threshold.

Sensor assisted head mounted displays for welding are disclosed. Disclosed example head mounted devices include an optical sensor, an augmented reality controller, a graphics processing unit, and a semi-transparent display. The optical sensor collects an image of a weld environment. The augmented reality controller determines a simulated object to be presented in a field of view, a position in the field of view, and a perspective of the simulated object in the field of view. The graphics processing unit renders the simulated object based on the perspective to represent the simulated object being present in the field of view and in the weld environment. The display presents the rendered simulated object within the field of view based on the position. At least a portion of the weld environment is observable through the display and the lens when the display is presenting the rendered simulated object.

A welding helmet includes a helmet housing; a headband structure for securing the helmet housing; a Head Up Display (HUD)-type auto-darkening filter secured in the helmet housing; and a light-permeable protective sheet installed in front of the HUD-type auto-darkening filter in the helmet housing, wherein the HUD-type auto-darkening filter comprises a head-up display which is used to reveal operating parameters of the auto-darkening filter, and the head-up display is arranged between a body of the auto-darkening filter and the protective sheet such that when the auto-darkening filter is in a transparent state the luminously revealed operating parameter of the auto-darkening filter can be imaged via the protective sheet into the eyes of an operator who wears the welding helmet.
