摘要:
An example system to represent data with multi-dimensional cyclic symbols is provided. The system includes a representation engine, a symbol engine, and a translation engine. The representation engine is to provide a plurality of display symbols. Display symbols are selected from a set of multi-dimensional cyclic symbols. The symbol engine is to receive a plurality of received symbols. The translation engine is to convert the plurality of received symbols into a plurality of display symbols.

The invention relates to an identity card, comprising a card body (201) and a physical unclonable function (203, 207) arranged within the card body, wherein the physical unclonable function comprises a first light influencing layer (203) and a second light influencing layer (207).

This inventive method assures the authenticity of drugs or other valuable substances that reside within product containers, such as syringes. The method includes initially measuring the 3D topology of the glass surface while determining the distance to the glass surface. Thereafter, a desired 3D code is written below the glass surface with a pulsed laser system. The written 3D code is readable using optical coherence topography (OCT) or parallel optical coherence tomography (pOCT) to verify the authenticity of the product container. A system uses this method with a plurality of syringes held within a tray, and a writing apparatus that moves relative to the tray to write a predetermined 3D code on each of the syringes held in the tray, during processing of the syringes along a process line while in the tray.

摘要:
A product package comprises an indicia printed thereon. The indicia comprises a set of visibly discernible individual dots. The dots are arrayed to form the indicia and at least a portion of the dots are offset from their nearest neighbor dots by less than one dot diameter in one direction or at an offset angle of other than 45 or 90 degrees.
