The anti-G trousers are partially double-walled and partially single-walled and made from an air-permeable, tear-resistant, refractory and stretch-resistant synthetic textile material of max. 130 gram/m.sup.2. In the double-walled areas, airtight pockets (13, 18, 34, 35) are thereby formed which act as pneumatic muscles and contract when being inflated from an automatic pressure supply and thereby draw the adjacent single-layer textile pieces towards one another. In this way, pressure is applied all over the surface of the pilot's body. The pockets (34) on the outer sides of the trouser legs extend upwards against the lower abdomen into a respective pouch-type bubble (13) and are connected to the pockets (35) for the inner sides of the trouser legs via an inguinal channel (18). The pockets (34) communicate on the rear side of the trousers via a connection channel. From here, in the lower back region, a coccyx channel extends downwards between the buttocks of the wearer. The front sides and rear sides of the trouser legs remain textile strips (14). They are breathable and allow for the discharge of body heat.

A display system includes an interface unit, a head worn display in wireless communication with the interface unit, and a first tracker sensor remote from a head of a user and configured to wirelessly sense a head pose and provide first head tracking data to the interface unit. The interface unit is remote from the head worn display. The display system also includes a second tracker sensor associated with the head of the user and configured to provide second head tracking data associated with the head pose to the head worn display. The interface unit is configured to receive the second head tracking data from the head worn display via at least one wireless link and provide video information for display on the head worn display via the at least one wireless link.

A neck protection system includes a support structure, helmet, force transmission arrangement, actuator arrangement, sensor arrangement, and controller. The force transmission arrangement is coupled to the support structure and the helmet and applies a relative force between them. The actuator arrangement applies a load to the force transmission arrangement to initiate the relative force between the support structure and the helmet. The sensor arrangement measures movement changes of a vehicle. The controller is connected to the sensor arrangement to receive data representing the measured movement changes, and connected to the actuator arrangement, and generates and sends control commands to the actuator arrangement based on which the actuator arrangement applies the load to the force transmission arrangement. The controller receives maneuver information from a control computer of a vehicle and generates the control commands based on the received maneuver information and/or based on measurements of the sensor arrangement.

A monitoring system (100″) is for aeronautical personnel (99), such as aircraft operators, pilots, co-pilots or passengers of airplanes or aircraft, such as aircraft or helicopters of civil or military aviation, passenger aircraft in scheduled or charter traffic, in particular also ultra-fast aircraft. The monitoring system includes a sensor system (60) for a measurement-based monitoring of the gas concentration. The operation of the monitoring system (100″) can be configured by an external input/output unit (450) or an external output unit (460).

A system comprising a scanner to scan the airman or soldier (subject), a processor to receive, from the scanner, a non-manifold three-dimensional (3D) digital surface model (DSM) scan data representative of the subject, and a computer-aided manufacturing (CAM) device. The processor recognizes anatomical features on the 3D surface model including the cephalic (head) region of the scanned subject; stores each sub region defined by anatomical features as a non-manifold 3D surface model; creates a surface offset from the DSM sub region; creates a closed volume within and between the DSM sub region and the offset surface representative of a solid 3D pilot flight equipment; and causes a computer-aided manufacturing (CAM) device to manufacture the solid 3D pilot flight equipment.

An aspect of the present disclosure is a G-tolerance improving device including a valve control unit configured to control an operation of a main system valve configured to control pressure of oxygen to be supplied to a user who is breathing with positive pressure applied to his or her airway, the oxygen from a main supply source configured to supply the oxygen to the user, and an operation of an auxiliary system valve configured to control pressure of an auxiliary gas to be supplied to the user, the auxiliary gas from an auxiliary supply source configured to supply, to the user, the auxiliary gas including highly concentrated oxygen that is oxygen at a higher concentration than the oxygen supplied from the main supply source, in which, when a breathing state of the user changes from an exhalation phase to an inhalation phase, the valve control unit controls an operation of the main system valve and the auxiliary system valve such that the auxiliary gas is supplied to the user for a predetermined time that is shorter than a time of the inhalation phase.
