Devices, systems, and methods, etc., that provide, in certain aspects, a two-point, adjustable, partially pliable, and releasable tensioning suspension that supports an anti-blunt-force frame connected to a protective helmet. The protective devices herein can be, for example, sport-level and military/law enforcement-level. The anti-blunt-force frame is positioned and balanced on the wearer's face by an impact absorbing face padding system, including a chin strap, cup or pad comprised of an impact protection material. Thus, in one aspect, the present devices, systems, methods, etc., include an adjustable facial protection system for a human comprising a crescent-shaped face protection element configured to withstand blunt force impact and a ballistic material element to prevent the penetration of ballistic and fragmentation projectiles at various force levels to meet different ballistic hazards. The systems can also include a protective helmet.

The present invention achieves technical advantages as a vehicle cabin, comprising a floor system formed of removable and reconfigurable floor segments extending from a vehicle frame, and a ceiling system formed of removable and reconfigurable ceiling segments disposed in the ceiling of the vehicle cabin. Floor segments that can be positioned to form a floor channel, therebetween. A fixture interface adapted to releasably secure a fixture to the floor system. The fixture can be slidably repositioned within the vehicle along the floor channel. One of the ceiling segments includes one or more of a lighting module, a ventilation outlet, a ventilation inlet, a display screen, or a touch control panel. The ceiling segments can be hexagonal.

The present invention achieves technical advantages as a pilot and passenger seating. An aircraft employs a pilot seat, comprising a contoured structure having ergonomically formed and padded surfaces, with left and right arm supports that include an articulated control knob, movable in three rectangular axes and rotatable about a vertical axis to provide one or more aircraft steering functions for an aircraft, and a touch-sensitive control surface for controlling one or more power system components. A passenger seat, having a contoured structure, having ergonomically formed and padded surfaces, a headrest, a seat, a left support member, and a right support member are adapted to cradle a portion of a passenger's body to support the passenger during travel.

The present invention achieves technical advantages as 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. The present invention 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.

An integrated helmet and respirator system comprises a shell defining a helmet portion, the helmet portion being bounded by a peripheral edge. An annular shroud has an upper edge and a lower edge, the upper edge removably attached to the peripheral edge of the helmet portion and the lower edge attached to an annular frame member. A front portion of the annular shroud defines a visor. A one-way exhaust valve is received within an opening in the annular frame member. The one-way exhaust valve is configured to allow an exhalation gas exhaled by a user to exit an interior of the integrated helmet and respirator system and to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system. A neck dam extends downward from the frame and is configured to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system.

A visor assembly for a helmet includes a helmet cover configured to couple to a helmet, a visor pivotably coupled to the helmet cover and configured to selectively pivot between a stowage position and one or more usage positions relative to the helmet cover, and a latching mechanism coupled to the visor. The latching mechanism includes a first pawl configured to rotate between a locked position and an unlocked position. The latching mechanism is further configured to releasably lock the visor in one or more of the stowage position and the one or more usage positions.

A connector for providing audio signals to reduce noise during transmissions. A multi-pin connector receives audio signals and a ground, power, and audio signal connector transfers the audio signals to a noise-reduction device. An audio output transfers audio signals from the multi-pin connector to an in-ear system and at, least one ear-protection device. A multi-pin signal separator in communication with the multi-pin connector, the ground, power, and audio signal connector, and the audio output can receive all or a portion of the audio signals from the multi-pin connector, the ground, power, and audio signal connector, and the audio output and can selectively pass the audio signals to at least one of: the in-ear system and the at least one ear-protection device, while accepting a plurality of pin configurations.

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. Embodiments include 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 face shield, such as a visor, mounts to a protective helmet using a mounting assembly. The mounting assembly has a base, a spacer assembly, and a pair of posts. The base is disposed on the interior of the helmet. The posts are connected to the base and extend outwardly through holes that are formed in the side of the helmet. The spacer assembly slides over the posts when the posts are inserted through the corresponding holes in the helmet, and frictionally engages the outer surfaces of the first and second posts such that the helmet is disposed between the base and the spacer assembly. The posts threadingly receive corresponding fasteners that attach the face shield to the helmet.

Helmet systems and their methods of use are described. In one embodiment, an opaque, ballistic rated visor is attached to a helmet such that the visor covers a wearer's eyes.
