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: 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: An emergency call system and a method for operating the emergency call system are provided. The emergency call system includes a mobile device and receiving stations. The mobile device has a radio module to transmit an emergency call and each of the receiving stations is configured as a router and has an alarm device and a radio module to receive the emergency call. The emergency call is transmitted from the mobile device to a first receiving station to trigger the alarm signal and a position of the mobile device relative to the receiving stations is determined. Depending on the position, only one of the receiving stations is selected to trigger the alarm signal.

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.

Abstract: The invention discloses a method and a device for the authentication of a document, a valued good or a packaging, carrying a marking (M) exhibiting a viewing-angle dependent light reflection spectrum. The authentication method is based on a measurement of the intensity of light reflected by the marking at least at two different viewing angles in response to a sequential wide-angle illumination with light of different spectral characteristics, and the comparison of the measured intensity values with corresponding reference values. The authentication device (1) has at least two light sources (4) of different spectral characteristics, a wide-angle illumination optics (3), and at least two photodetectors (5) collecting light reflected by said markings at least at two different viewing angles.
