Abstract

The present invention provides a method for marking thread or fibre. The thread or fibre is made to pass through a coating solution comprising particles of a marker material so as to apply the marker material to the thread or fibre (110). Thereafter, the thread or fibre is subjected to a curing process (120). Presence of the marker material is detectable even after the thread or fibre has been subjected to extreme handling conditions (130).

Abstract

A method and system for establishing integrity of an item is provided. The method comprises the steps of: performing laser-induced breakdown spectroscopy on an item to obtain a first representative spectrum (510); comparing the first representative spectrum to a plurality of stored laser-induced breakdown spectra (520); and establishing integrity of the item based on the comparison (530). The plurality of stored laser-induced breakdown spectra preferably comprise a spectrum representative of an item comprising at least one predetermined element and a spectrum representative of an item that does not comprise the at least one predetermined element.

Abstract

A process for real-time classification of materials, the process including: conducting laser induced breakdown spectroscopy on the material (LIBS), wherein at least one second laser pulse is directed to the plume so as to selectively energise only a portion of the plume; measuring optical emissions from the energised portion of the plume; and assessing the elemental composition of the material on the basis of the optical emissions from the excited portion of the plume; wherein the energised portion of the plume is substantially smaller than the entire plume so that the measured optical emissions are relatively independent of the size of the entire plume and hence are relatively independent of the optical absorption and vaporisation characteristics of the material, thereby allowing a more accurate assessment of the elemental composition of the material than if the assessment was based on the optical emissions from the entire plume.

Abstract

An elongated carrier (110) comprising a plurality of discrete indicia (120) dispersed in or on the elongated earner (110) and a machine-readable identification marker applied substantially homogeneously to the elongated carrier (110), is disclosed. The indicia (120) comprise identification data unreadable by a naked human eye.
