HELMET WITH PROJECTION SYSTEM Russian patent published in 2014 - IPC G02B23/10 G02B23/00 G02B27/14 

FIELD: personal use articles.

SUBSTANCE: invention relates to devices for protection of human head and deals with a helmet with a projection system. The helmet contains a controller, a video camera, a data receiving/transmitting unit, a speech recognition unit, a unit for determination of the helmet spatial position and an optical system. The optical system includes an image generator based on a scanning laser module, a scanner lens, a unit for exit pupil diameter magnification, a projection optical system and the helmet transparent shield (visor) through which one simultaneously observes the surrounding situation and views graphical information being transmitted. The projection optical system consists of a nonaxisymmetric component, a flat mirror and an axisymmetric lens. The projection optical system is designed so that to enable receipt of control commands and information from the speech recognition unit and the unit for determination of the helmet spatial position. The data receiving/transmitting unit is designed so that to enable data exchange via wireless networks.

EFFECT: improvement of image quality and simplification of control of the helmet systems.
