Abstract:
A method of providing a mark to a case of a cartridge of ammunition. The mark includes at least one sub-mark and is suitable for identification and/or for tracking of the cartridge. At least one indenter selectively radially indents a circumferential surface of a bottom of the case, thereby forming the at least one sub-mark.
Abstract:
Scanner, method of scanning and system for scanning that allows detecting decay time characteristics of light emitted by a luminescent marking on an item which is transported, even at high speed, on a distribution/production line. The detection zone of the scanner's light sensor has a shape elongated along a path of the moving item, and the responsivity of the light sensor, within the wavelength range of the emitted luminescence light, is uniform over the detection zone. The drive current, or drive voltage, powering the excitation light source is adapted to deliver the intensity of the excitation light to the marking so that its light sensor can reliably measure the corresponding luminescence light response, and thus accurately determine a corresponding decay time value.
Abstract:
The present invention describes a method of providing a mark to a case (13) of a cartridge (1) of ammunition. The mark comprises at least one sub-mark (12) and is suitable for identification or for tracking of the cartridge (1). According to the present invention, at least one scratching means (10) selectively incises a surface of the case (13), thereby forming the at least one sub-mark (12).
Abstract:
Decoding or encoding information in a two-dimensional barcode, the barcode comprising an orientation pattern and a payload data pattern both being compiled of first and second type elements. The decoding or encoding involves a two-dimensional transformation applying at least to the payload data pattern in connection with second information that forms together with first information the information encoded in the two-dimensional barcode.
