A mounting device having a mounting assembly for mounting a pair of goggles to a helmet is provided. The mounting assembly is configured to provide at least three degrees of freedom of movement using one or more actuation mechanisms for locking and unlocking a position of the mounting device. The number of actuation mechanisms is less than a number of degrees of freedom. In some aspects, the number of actuation mechanisms is one. A rotation base connects the mounting assembly to the helmet, and a goggle linkage connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism, and a floating friction brake mechanism, are provided.

Protective headgear including central, left lateral, and right lateral trunks, and which may include at least one external, remote handle for directing air flow.

A helmet-mounted display systems includes a front mechanical arch comprising a display device and a means for holding and adjusting the display device in the vertical plane, the means consisting of a first vertical support surface comprising an oblong port and a screw/spring assembly, the screw passing through the oblong port and being fastened in a mechanical structure of the display device, the display device being capable of rotating in such a way as to make it retractable. The display system comprises a means for roll adjustment and repositioning of the display device, the adjustment means consisting of a second vertical support surface, normal to the first support surface, and a knurl screw attached to the mechanical structure of the display device, the end of the screw resting on the second support surface when the display device is in the use position.

A surgical helmet assembly can be securable to a mixed reality device and can include an inner frame, an outer frame, and a surgical hood. The inner frame can be securable to the mixed reality device. The outer frame can be releasably securable to the inner frame, where at least a portion of a lens of the mixed reality device exposed through the inner frame and the outer frame. The surgical hood can be connected to the outer frame and can be configured to cover at least a portion of a head of a user.

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 screen device includes a combiner that shows an image projected by a helmet at the helmet; and a vertical movement mechanism attached to a shell of the helmet, wherein the vertical movement mechanism supports the combiner so that the combiner is movable in a vertical direction and so that an inclination of the combiner is changeable with respect to the vertical direction.

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.

The binocular bridge system is configured to couple two night vision monoculars together, effectively providing the user with a binocular night vision system. An example binocular bridge system comprising: a bridge; a first hinged arm that includes an objective alignment ring configured to fit around an objective lens locking ring of a night vision monocular secured to the first hinged arm; and a second hinged arm that includes an objective alignment ring configured to fit around an objective lens locking ring of a night vision monocular secured to the second hinged arm. The hinged arms in conjunction with the objective alignment rings are configured to mechanically collimate the night vision monoculars secured to the first hinged arm and the second hinged arm of the binocular bridge system.

An infrared motorcycle helmet device is provided. The infrared motorcycle helmet device includes a helmet. The helmet has an opening on a front portion of the helmet. An external visor is placed on an external surface of the helmets. The external visor can be moved into a position over the opening as desired. An infrared camera is placed on an external surface of the helmet.
