Embodiments provide methods for storing a respiratory mask. In one embodiment, the respiratory equipment may include a respiratory mask having a front side and a rear side and a cavity having an opening in the rear side. There may also be provided an inflatable harness adapted to maintain the respiratory mask against the user face, and a storage element comprising a housing. In one embodiment, the method may include pulling on the harness on the front side of the respiratory mask in order to place the harness on the respiratory mask in an storage position outside said cavity, and maintaining the harness on the respiratory mask in the storage position and inserting the respiratory mask into the housing of the storage element.

A device for regulating breathing gas delivered to a user, comprising a gas circuit comprising a main line having at least an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to at least one user station such as a mask, the main line comprising at least one electromechanical control valve configured to regulate the gas pressure between the upstream and the downstream, the circuit comprising a secondary line comprising an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to the same user station(s), the secondary line comprising at least one auxiliary member for regulating the gas flow, the device comprising a switching system configured to control the flow of gas between the upstream and the downstream of the circuit via the main line or via the secondary line, characterized in that the auxiliary member for regulating the secondary line is a pneumatic pressure regulator.

A plurality of image capturing devices capture the scene in front of the aircraft. Information regarding the three-dimensional geometry of the windscreen is used to trim the raw image data from the image capturing devices. The remaining image data in a zone-of-interest is processed to detect glare in the field-of-view visible through the windscreen. The trimming operation reduces the amount of time and processing resources needed to perform glare detection. Information regarding the position and viewpoint of the pilot and co-pilot are also provided to the glare reduction module. The glare reduction module generates a translucent overlay on the windscreen or OSTD for both the pilot and co-pilot to block or reduce the glare.

A system may include a structure, a head wearable device, emitters, receivers, and a processor. The emitters may be configured to emit signals and may be implemented on at least one of the structure or the head wearable device. The receivers may be configured to receive at least some of the signals from the emitters, to detect at least one signal property including signal intensity of the received signals, and to output information of the at least one signal property as signal data. The receivers may be implemented on at least one of the structure or the head wearable device. A processor may be configured to: receive the signal data from the receivers; determine a position and an orientation of the head wearable device based on the signal data; and output image or symbolic data to the head wearable device to be displayed by the head wearable device.

Disclosed is a connector for providing audio signals. The connector can include an audio signal and power cable having a first end and a second end, and an interface communication connector disposed at least proximate to the first end. Further, the connector can include a ground, power, and audio signal connector disposed at least proximate to the second end, wherein the ground, power, and audio signal connector is configured to accept a plurality of different audio signal and power cables from different noise-protection devices having differing pin configurations. Further still, the connector can include at least a first audio input signal cable in contact with the audio signal and power cable, wherein the audio input signal cable is configured for transmitting one or more of the audio signals through the interface communication connector to at least one of a vehicle and an extra-vehicular source.

A method of constructing a reduced drag wing, including: providing a top wing surface panel; coupling a top surface external leading-edge panel to the external surface of the top wing surface panel, wherein the top surface external leading-edge panel extends forward from the top wing surface panel and extends rearward covering at least partially the top surface external leading-edge panel; coupling internal rib elements to the interior surface of the top wing surface panel; coupling the top surface external leading-edge panel to a sleeve element; coupling the rear sleeve element to a bottom wing surface panel; coupling the internal rib elements to the interior surface of the bottom wing surface panel; and coupling the top surface external leading-edge panel and the sleeve element to a releasable mechanical mechanism. A reduced drag wing for a wingsuit. A wingsuit including a reduced drag wing.

Acceleration protective trousers or G-protective trousers are double-walled forming airtight compartments. The trousers include an air-permeable, tear-resistant, fire-resistant and low-stretch synthetic textile material, and the trousers are provided with compartments which can be inflated into a circular cross-section. These compartments act as muscles by two opposite edges being pulled together and the adjacent pieces of textile material being stretched. These compartments extend along the trouser legs and are connected at the upper end of the trouser legs. The compartments on the outer sides of the trouser legs extend upwards from the groins and terminate in a bag-like bladder towards the lower abdomen. On the rear side of the trousers they communicate with one another via a connecting channel. A coccyx channel branches off downwards and extends towards the crotch. The compartments communicate via at least one hose with raccord with an automatically meterable compressed air supply.
