A real-time virtual reality welding system including a programmable processor-based subsystem, a spatial tracker operatively connected to the programmable processor-based subsystem, at least one mock welding tool capable of being spatially tracked by the spatial tracker, and at least one display device operatively connected to the programmable processor-based subsystem. The system is capable of simulating, in virtual reality space, a weld puddle having real-time molten metal fluidity and heat dissipation characteristics. The system is further capable of importing data into the virtual reality welding system and analyzing the data to characterize a student welder's progress and to provide training.

An aircraft having an augmented reality flight control system integrated with and operable from the pilot seat and an associated pilot headgear unit, wherein the flight control system is supplemented by flight-assisting artificial intelligence and geo-location systems is presented. The present disclosure includes an augmented reality flight control system incorporating real-world objects with virtual elements to provide relevant data to a pilot during aircraft flight. A translucent substrate is disposed in the pilot's field of view such that the pilot can see therethrough, and observe virtual elements displayed on the substrate. The system includes a headgear that is worn by the pilot. A flight assistance module is configured to receive data related to the aircraft and provide predictive assistance to the pilot during flight based on the received data based in part on a pilot profile having preferences related to the pilot.

A method of displaying an image on a see-through display comprises: obtaining a first electro-magnetic radiation matrix of radiation intensity values of an object; dividing the first matrix into a second matrix representing a first subset of the radiation intensity values, and a third matrix representing a second subset of the radiation intensity values; generating a first grayscale image with an enhanced contrast representing the first subset of the radiation intensity values from the second matrix; colouring the first grayscale image with a first colourmap to obtain a first colour image; generating a second grayscale image representing the second subset of the radiation intensity values; colouring the second grayscale image with a second colourmap to obtain a second colour image; combining the first colour image and the second colour image; and displaying the combined colour image on the see-through display.

A personal protective equipment wearing detection apparatus is provided which can accurately detect the approach or contact of a person's head by use of a plurality of contact detection sensors. A personal protective equipment wearing detection apparatus 100 includes a headband contact detection sensor 110 and a chin strap contact detection sensor 120, which are mounted on a headband 92 and a chin strap 94 of a helmet 90, respectively. The headband contact detection sensor 110 and the chin strap contact detection sensor 120 are connected to a controller 103 of a detection apparatus body 101. While one of the two contact detection sensors, the headband contact detection sensor 110 and the chin strap contact detection sensor 120, outputs a contact detection signal to the controller 103, the controller 103 connects the other contact detection sensor to GND.

A helmet mounted display is embedded in a visor assembly. The visor assembly comprises two molded sections that define portions for receiving waveguides. The optical components are disposed in a portion of the visor assembly and the entire assembly is attached by a hinge to the helmet. The visor assembly includes lateral clips to secure the visor assembly to the helmet, and a night-vision goggle attachment point.
