Lamp activation means are automatically controlled by positions calculated by the computer so that the lip light lights, with one of its lighting levels, when it is oriented in a direction contained within a predefined area.

Abstract: The general field of the invention relates to binocular helmet viewing devices worn by aircraft pilots. In night use, one of the drawbacks of this type of device is that the significant distance separating the two sensors introduces hyperstereoscopy on the images restored to the pilot. The method according to the invention is a scheme for removing this hyperstereoscopy in the images presented to the pilot by graphical processing of the binocular images. Comparison of the two images makes it possible to determine the various elements present in the image, to deduce therefrom their distances from the aircraft and then to displace them in the image so as to restore images without hyperstereoscopic effects.

Abstract: The disclosure relates to the ergonomics and safety of head equipment, notably incorporating display devices, intended to be worn by aircraft crew. One of the difficulties in evaluating injury risks associated with the wearing of head equipment is to determine precisely the center of gravity of the actual user's head, since standard head models prove to be too imprecise. The invention proposes a process enabling individualized determination of the center of gravity of the user's head and therefore its precise position relative to the center of gravity of the head equipment. One preferred embodiment of said process is to establish a three-dimensional mapping of the external surface of the user's head.
