IMPACT-POINT METHOD FOR DIRECT APPLICATION OF NOISE-PROOF SYMBOLIC LABELS AND APPARATUS FOR READING AND DECODING THEREOF Russian patent published in 2014 - IPC G06K1/12 

FIELD: physics.

SUBSTANCE: method includes applying noise-proof symbolic labels consisting of information elements formed on the surface of the labelled components in the form of conical depressions during needle-impact labelling, wherein the conical depressions are formed by mechanical action of a sharp needle on the surface of the components through an auxiliary polymer film while simultaneously depositing on the formed walls of the conical depression craters corrosion-resistant powdered yttrium oxysulphide phosphor activated with ytterbium and erbium, and a solution of a polymer resin in ethyl acetate, removing the auxiliary film from the surface of the component with the remaining amount of phosphor and the resin solution after transfer of a portion thereof by the sharp needle onto the walls of the conical depression craters while pricking the film and subsequent action on the labelled surface. The auxiliary film is placed on the labelled surface using a two-component resin solution and a corrosion-resistant powdered phosphor to the processed surface of the component, and the apparatus for reading and decoding the symbolic labels further includes light-emitting diodes with wavelength of 980 nm and a light filter.

EFFECT: high reliability of protection.
