20110297749 | VERIFIABLE SYMBOLIC DIRECT PART MARK AND METHOD OF ITS FABRICATION - Direct application symbol mark which consists of information elements which are formed in needle-impact marking on the surface of the part being marked in the form of conical depressions and which are filled with paint, characterized in that an adhesively fixed film with the recorded optical information with perforated openings which coincide with the depressions is located overhead on this surface, and the paint which is used for filling is fluorescent. | 12-08-2011 |
20110192967 | DEVICE FOR READING LUMINESCENT SYMBOLS AND IMAGES - Optical device which is designed to read information in the form of luminescent symbols and images, which consists of an illuminator with an array of light emitting diodes which excite luminescence and an optical system which projects the information which is being read onto the sensor of the scanner of the optoelectronic system which consists of an electronic control circuit, optical filter and objective lens with a light-guiding lamp which is provided with an output window, and which is connected to the housing of the data collection terminal or scanner by a constructive connection and switching connections for controlling the light emitting diodes of the device, characterized in that the switching connections between the scanner and device are implemented optically by photosensors which control the illuminator and sighting system, which are mounted in the housing of the device, and which receive the light pulses of the scanner. | 08-11-2011 |
20110095088 | FLUORESCENT INFORMATION MARK AND METHODS OF ITS FABRICATION - The invention is aimed at devising a direct application symbol mark (SMPN) which is for example two-dimensional, in which the information elements, for example depressions of the needle impact mark or regions processed by laser radiation in laser engraving using the methods described in the invention are filled with fluorescent dyes which absorb radiation at wavelengths for example either up to the short-wave transmission edge of the filter of the reader, for example in the 250-600 nm range, and which radiate in the wavelength range of the passband of the receiving channel of the reader, for example 600-700 nm, or which absorb radiation at wavelengths greater than the long wave transmission edge of the filter of the reader, for example in the 700 nm-10 micron range, and which radiate in the wavelength range of the passband of the input filter of the reader, for example 600-700 nm. | 04-28-2011 |
