Title:
DISPENSING SYSTEM FOR APPLYING DNA TAGGANTS USED IN COMBINATIONS TO TAG ARTICLES
Document Type and Number:
WIPO Patent Application WO/2019/140101
Kind Code:
A1
Abstract:
A dispersant system comprises a plurality of taggant vessels, each having a taggant that corresponds to a position in a tag string and a computer controller convert the tag string into a selection of a taggant set while computer-controlled valves allow or block a flow of taggants to a manifold output tube. From the output tube, a mix of the taggants flow to form a dispersant formed according to the tag string. A nozzle disperses the dispersant onto an object to be tagged, possibly atomized with air. The taggant can comprise a DNA taggant comprising a static portion and a dynamic portion that is unique to each tag string position. Tag strings for adjacent lots might have a low Hamming distances to reduce cross-contamination and/or have redundancy for error detection and correction and selected so that consumption of taggants evens out over the plurality of taggant vessels.
