To provide a method for securing an object.SOLUTION: A method for securing an object includes: embedding at least two micro transponders (MTPs) into a taggant, a plurality of taggants, a packaging, or the object, or a combination thereof to generate at least one legitimate matched pair, the MTPs each being configured with respective identifiers; indexing the respective identifiers of the MTPs to the object; storing indexing information associated with the MTPs and the object in a database of a digital security system; reading the respective identifiers via an identifier reader; and verifying, on the basis of the reading, the indexing information to determine whether the respective identifiers are associated to the legitimate matched pair.SELECTED DRAWING: None

The invention relates to a method, and a corresponding system, capable of checking whether genuine SERS or SERRS taggants having a unique characteristic surface enhancement scattering feature are present or not on a machine-readable marking applied on a value document by using a Raman spectrometer adapted to perform a Raman Spectroscopy analysis of the marking. The method according to the invention allows a reliable and fast detection of a presence of the SERS / SERRS taggants, and is particularly suitable for checking authenticity of value documents, e.g. such as banknotes, moving with respect to the Raman spectrometer with a given speed, and possibly with a high speed, or briefly exposed to the Raman spectrometer.

To provide a method or instrument for manufacturing components for an aerosol generating article improving quality assurance.SOLUTION: A method for manufacturing components of an aerosol generating article 401 including a taggant includes: a step for applying the taggant to a component; a step for detecting an amount of taggants included in the component; a step for determining whether or not the detected amount of the taggant is smaller than a first prescribed amount; and a step for rejecting the component when the detected amount of the taggant is smaller than the first prescribed amount. An instrument for manufacturing components of an aerosol generation article is provided with: a dispenser applying the taggant to the component; a sensor detecting an amount of taggants included in the component; a controller for determining whether or not the detected amount of taggants is smaller than the first prescribed amount; and a rejection system for rejecting components when the detected amount of taggants is smaller than the first prescribed amount.SELECTED DRAWING: Figure 4

The present invention provides spectral code strategies that allow spectral codes to be accurately and consistently deployed in a wide range of substrates and background situations. The present invention uses taggant particles with a multilayer structure that is able to produce a strong, consistent spectral signal that is resistant to background noise effects. The spectral output can be read remotely from a distance using multispectral, particularly hyperspectral, imaging techniques.

A Cascade Spoof Proof Extra-layer Radiant Authentication (CASPER-A) system using spectrally-coded taggants is configured to transmit a multi-wavelength optical interrogation signal to interrogate a nanotag associated with a device. A multi-spectral optical receiver may be configured to receive and decode a response to the interrogation signal that may comprise a multi-spectral emission generated by the nanotag. Processing circuitry may generate data from the decoded response. To authenticate the device associated with the nanotag, the processing circuitry may generate a digital signature. The nanotag may comprise a multi-layered nanocrystal (NC) activated composite material comprising multiple layers configured to generate a multi-spectral emission from optical excitation by the optical interrogation signal. Each layer may comprise a heterogeneously dispersed volume embedded with quantum dots (Qdots). The Qdots may be configured to generate a multi-spectral emission based on an interaction of one or more wavelengths among Qdot emitters by intercoupling.

There is provided an aerosol-generating article (10) comprising an aerosol-forming substrate (12) and a taggant (60). The taggant (60) comprises a photoluminescent material having an emission half-life of between about 50 microseconds and about 1000 microseconds after photoexcitation of the photoluminescent material. Also provided is an aerosol-generating system (100) comprising the aerosol-generating article (10) and an aerosol-generating device (1). Also provided is an aerosol-generating device (1) comprising a source of radiation and a photodetector.

A system is provided for checking a presence and integrity of taggant applied to components of aerosol-generating articles during manufacture of the aerosol-generating articles on a manufacturing line, the system including: a first sensor configured to detect a taggant applied to a surface of a material web and to determine that the taggant has been applied to meet a predetermined continuity of application quality condition; and a second sensor located downstream of the first sensor on the manufacturing line, the second sensor configured to inspect portions of the material web after the material web has been cut into portions and to confirm at least one of a predetermined profile of the taggant and a predetermined concentration of the taggant. A method of checking a presence and integrity of taggant applied to components of aerosol-generating articles during manufacture of the articles on a manufacturing line is also provided.

To provide a method for uniquely identifying a target recyclable product in a continuous feedstock of a mixed recyclable product.SOLUTION: A method for uniquely identifying a target recyclable product in a continuous feedstock of a mixed recyclable product includes steps of: capturing a digital image of a recyclable product; creating a trained database of the digital image of the recyclable product; recognizing the recyclable product in the digital image; collating the recognized image of a target recyclable product with information on a product database; and separating the target recyclable product from a feedstock for subsequent recycling. The step of separating the target recyclable product from the feedstock for the subsequent recycling is achieved at a conveyor detection speed of about 1 m / sec or more and about 3 m / sec or less.SELECTED DRAWING: Figure 1
