COLLIMATOR DIGITAL INDICATOR Russian patent published in 2020 - IPC G01D7/08 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the electro-optical instrument-making, in particular, to the collimating aviation indicators (CAI) for displaying on the windshield the sign-graphic flight information. Collimator digital indicator (CDI) comprises a housing, a collimating head consisting of a semitransparent mirror and a system of optical lenses, a control panel connected through a collimating head with bundles to the housing, in which there is a liquid crystal imaging device (LCID), consisting of a display module, a backlight module and a display controller, an electronics unit consisting of a secondary voltage module, module of graphic processor, to the second inputs-outputs of which LCID inputs and outputs, display processor module and interface module are connected, which are connected by common inputs-outputs along data exchange lines and multiplex channel of information exchange (MCIE). Modules of the electronics unit mesonically connected along the perimeter by contact bushes with low-resistance conductive coating made of silver group metals have printed-circuit boards with external layers of polygon-type housing grounding, contact points of which with the housing are open from the mask.

EFFECT: technical result consists in simplification of design and reliability of collimator, reduction of dimensions.
