Definitions

  • the presented embodiments are generally related to data storage devices, more specifically to optical storage devices in the form of stable or biodegradable polymer film that can store encoded information about a physical good, such as but not only: medical drugs, cosmetics, medical and food products, or other engineered materials and physical goods.
  • Consumer and industrial goods include various data storage and protection devices such as barcodes, holographic stickers, and similar. These are generally belonging to the packaging of the good and could be optically decoded if needed but most often can be easily falsified or removed from the packaging and replaced.
  • Certain types of raw materials and manufactured goods may differ in shape or color; thus identification can be performed visually, wherever possible, by a specialist (e.g., pharmacist) or automatically via a computer vision system. While the form most often remains unchanged, the color of goods (e.g., tablets and other medications) can vary within wide limits (prescribed in the standard instructions for medicines), which undoubtedly complicates the installation of authenticity during a routine visual examination. The same goes for the size and shape of the package.
  • a data storage device for a medical drug (in tablet), cosmetics, or other medical and food products include a thin polymer film with indentations and/or surface-reliefs which encodes general and/or security information about the specific drug, its contents, date of manufacturing and best before date.
  • the decoding process may be done as follows: due to local optical thickness differences along the plane of a film, a laser beam that passes through the film or is reflected will undergo a define modulation of its phase which will result in production of a certain complex diffraction pattern on a screen or any matrix-type light detector.
  • the initial complex amplitude distribution along the laser beam and/or its state of polarization and/or its wavelength may also be varied to add another layer of protection for such data storage devices thus, a valid diffraction pattern can be achieved only with a defined ‘decoding’ configuration of the laser beam, otherwise, the resulting diffraction pattern will be meaningless.
  • the main advantage of optical encoding is a higher number of degrees of freedom, which could be used to extend the level of protection for an arbitrary substance compare to other methods such as radio- and water- marks or other type of protection solutions.
  • the decoding process can also be performed through analysis of photographic images of the encoded patterns.
  • Required information about the tablet may be encoded in various ways, for example:
  • polymer encoding is based on using sensitive polymers.
  • Polymer film with patterns while made, for instance, form polymers or their components sensitive to temperature (temperature dependent polymers such as PNIMAN) could undergo phase transition and elimination of diffraction pattern while heat over phase transition, or humidity (for hydrophilic polymers) or other sensitivity.
  • Temperature dependent polymers such as PNIMAN
  • the information encoded by patterned polymer films incorporated into the medical tablets, cosmetics, food products, and other goods can be used for tracing these items during their manufacturing, transportation, selling, and consumption. Regulations (governmental, industrial, standards) of the use of these goods can be implemented using this laser readout technology to follow and trace single goods.
  • Fig. 1 shows the fabrication process of the medical drug in the form of a tablet with an embedded polymer data storage device.
  • Fig. 2 pointed out the basic optical schematic for the decoding process needed to recover stored information.
  • Fig. 3 Different kinds of grids like square or hexagonal in nodes of which an indentation and/or surface-reliefs are made.
  • Fig. 4 describes possible cross-section views of the polymer-based data storage device.
  • Fig. 5 and fig. 6 reflects a few of possible designs for cosmetic packaging with embedded polymer tag.

  • Fig. 1 Two halves of a pill 1, 3 with a hole 5 in the middle are pressed against each over to fix the polymer data storage device 2.
  • 4 is the completed tablet drug with embedded polymer data storage device.
  • the process of tablet formation with a polymer film consists of three stages. 1 stage - independent synthesis of 2 parts of a tablet from the medicinal substance in a press-mold using a hydraulic or some other press. The configuration of the press-mold can be different and allows for the manufacture of tablets of different sizes; forms; thickness; diameter, shape, and position of the hole for reading information from a polymer film. 2 stage - placing a polymer data storage device between two independent parts of a tablet. 3 stage - pressing of two parts of the tablet among themselves. The general principle is indicated here. However, the polymer data storage device position in the tablet and the number of formation steps can vary.
  • Fig. 2 The possible optical scheme for the readout process of the tablet drug 7.
  • a coherent laser beam 6 with the identified complex amplitude distribution, polarization and wavelength is passing through the polymer data storage device via a specific hole.
  • Lens 9 is placed in such a configuration that polymer data storage device and an array of photosensitive elements 11 are located in front and back focal planes of the lens, respectively (Fraunhofer diffraction case).
  • a resulted diffraction pattern 10 is then digitized and fed into the specialized software that performed a decoding process.
  • Low focal length lenses could be used to minimize the size of the optical decoding unit so it could be incorporated in a specific field environment with ease.
  • Fig. 3 A few of many possible arrangements of the local indentations and/or surface-reliefs along the plane of the polymer data storage device.
  • the grid could be square 13 or, for instance, 14 - hexagonal. Such grid difference will result in unique diffraction patterns which could be used for one-to-one mapping of the specific pills’ classes.
  • the grid could preserve periodicity along the whole plane of the polymer data storage device or be partially periodically within a local vicinity and such periodical clusters could be spread along the plane of the polymer.
  • the polymer film with structured microrelief (micro-terrain) and/or patterned structure are produced using conventional lithography approaches. It could be done through the fabrication of photolithography mask in silica (or other ceramic) and later transform to replica of PDMS stamp (as example of widely used in microtechnology. Then the polymeric microrelief/pattemed structure is produced by dip-coating and printing or imprinting of stamp (PDMS or other solid support) into a polymer.
  • stamp PDMS or other solid support
  • the thickness of the polymer film could be down to a few micron, and polymer may represent FDA approved list of polymers (e.g., polylactic acid, poly (lactic-co-glycolic acid), polycaprolactone, gelatin, pectin, and others (including copolymers)). Patterned structure and the transfer of structure should be done sufficiently accurately to ensure the diffraction from the final film of edible polymer.
  • polymers e.g., polylactic acid, poly (lactic-co-glycolic acid), polycaprolactone, gelatin, pectin, and others (including copolymers).
  • the described method for creating a patterned film is one of several possible methods. Other methods for applying relief with sufficient quality to implement reliable coding can be used to apply microrelief.
  • Fig. 4 The cross-section view of the polymer data storage device indicates the possible forms of indentations and/or surface-reliefs. 14 are the spherical indentations periodically distributed along the plane of the polymer. In such configuration, the diffraction pattern observed on the photosensitive elements 11 will be presented in the form of bright spots with a period that is a reciprocal of the indentation’s period.

  • Figures 5 and 6 represent one of many possible solutions for tagging a packaging of the cosmetic entities such as creams and mascara, respectively.

  • Clear window 17 inside a threaded cap in a combination with empty pillar 20 allowing a free laser beam passage though a polymer film 18 mounted on top of the pillar 20 or embedded into the metallic foil seal usually used to prevent air flow inside the flask for better storage.
  • Mascara tubes could also be tagged by our polymer films. For instance, a clear window could be made inside the handle, thus allowing the placing of the film. Such tags placing allows product verification without damaging any of the manufacturing packagings.
  • Fig. 7 shows a possible flowchart of polymer tag fabrication process.
  • an appropriate encoding algorithm is chosen (for instance, it could be a bar or QR code).
  • data from the encryption algorithm is transformed into the discrete and quantized phase shifts along the polymer film using an iterative Fourier transform algorithm (IFTA [US9766456B2]). From this point, a few of many fabrication processes are discussed.
  • IFTA iterative Fourier transform algorithm
  • the right branch on fig. 7 describes an optical approach: a high-power laser source 23 with the help of steering optics and objective lens 24 vaporize excessive polymer material, thus adjusting the physical thickness of the film to meet the desired phase shifts distribution [US8670151 B2] .
  • the left branch of fig. 7 reflects the more standard embossing approach.
  • a high precision master negative mold 25 is fabricated through a lithographic process. After the molding process 26, the polymer film 27 obtains a thickness distribution along its plane, thus leads to the same result as in the right branch.
  • the invention represents a medical tablet encoding that is made on an edible thin polymer film integrated or firmly tied to the tablet, wherein the polymer film produces a readable optical image (diffraction pattern). Such encoding can also be embedded in hermetically sealed packaging for cosmetics, food, other medical tools, devices, and other goods.
  • the main component of the soft gel pills is gelation. This type of pills always contains liquid medicine.
  • Softgel material is antioxidant, which means that the contents have a long shelflife and are well protected against UV rays and oxidation.
  • the custom pattern could be produced directly on the smooth gelatin surfaces via the hot embossing process. Preheated silicon stamp is pressed against the surface of the soft gel pill with a light force, thus producing indentations and reliefs.
  • Pre-filled syringes are usually used to store expensive liquid medicine like vaccines, insulin etc. Besides protective labels on the body of the syringe, there are no strong protection levels against the liquid interchanging.
  • Polymer film with a distinct pattern is glued on the tip of the syringe after a particular medicine in the form of a liquid has been filled inside the syringe during the manufacturing process.
  • a support, made of the same polymer is placed underneath the film to provide a flat reference surface. Before the injection, the polymer seal is punctured allowing liquid to flow through.
  • Some liquid medicines come in the form of glass bottles for multi-dose usage. These bottles are usually sealed with a hermetic rubbery stopper and metal tear-off cap. Our label could be placed on top of the rubber seal; thus after a metal cap is removed to obtain the contained liquid, a syringe needle must puncture both the rubber seal and the label damaging them and making the label unreadable.
  • the laser beam is guided via the beam splitting plate to the glass window.
  • Medicine in the form of the soft gel pills or pre-filled syringes is gently pressed against the glass window with enough mechanical force, thus flattening the pill’s surface with the embedded pattern or the film’s surface on the tip of the syringe, allowing a stable readout process.
  • the light’s intensity distribution in the complex diffraction pattern produced by the lens is captured by the photosensitive element.
  • the polymer film is integrated into the structure of the tablet, and removal of the polymer film will destroy the integrity of the tablet.
  • the polymer film has a micro-pattern and thickness from 0.1 to 50 micron.
  • the polymer film is made of a material that is editable (if needed to be consumed) and consists of pure or blended polymers (for example, polylactic acid, polysaccharides, gelatin, pectin, PLGA or a combination of thereof).

  • the polymer film is made of a material or a combination of materials that are non-degradable (for other applications, cosmetics, coding of other goods).
  • the polymer film is integrated into the tablet either by placing it in the center of the tablet (for example, by pressing two parts of tablets having a hole in between) or by placing it aside or in other part or associated by other means.
  • the polymer film is to be associated with a good by any means implemented in such a way that their separation (the good and the film) will indicate that a marking of good is damaged and not valid anymore. Such good should not be used since the integrity was compromised.
  • encoded information in the polymer film is recorded in imprinted or by another way via impacted periodic or non-periodic structure with micro-relief or pattern
  • the polymer film integrated into medicine may contain information about the composition of the medicine, characteristics, manufacturer, production date, expiration date, or any other information important for the patient, doctor, pharmacist, or regulating authorities.

  • Relevant data i.e., serial number or picture
  • the reliefs can vary in their shape, size, and depth.
  • Such configuration and encoding of indentations or reliefs are targeted to increase the difficulty of observing and/or modifying an embedded pattern.

Abstract

L'invention que nous proposons est une solution de stockage de données à base de polymère pour l'identification (marquage), le suivi et la logistique suite à la livraison et à l'utilisation de marchandises, la mise en œuvre physique d'une telle solution pouvant être techniquement possible. Notre solution est techniquement articulée au moyen d'une feuille mince ou d'un film stable à un environnement d'utilisation ou d'un polymère biodégradable (y compris la possibilité qu'il s'agisse d'un polymère comestible) avec des indentations périodiques ou non périodiques ou des reliefs de surface, qui modifient son épaisseur optique, afin de l'utiliser pour coder et stocker les données. Les informations peuvent être récupérées par analyse du motif de diffraction formé sur un détecteur de lumière en raison du passage d'un faisceau laser à travers le film polymère ou sont réfléchies sur ce dernier. Un film mince polymère est directement intégré (ou associé fermement) dans la marchandise, dans laquelle la conception technique du produit physique permettrait un passage de faisceau laser.
