Sealing a package with a visually transparent sealing label is described. The visually transparent sealing label contains an ultraviolet blocking component to prevent transmission of ultraviolet radiation through the label to the surface of the package. The package comprises an activatable component that upon excitation with ultraviolet radiation emits luminescence. The presence of the sealing label on the package may be verified by illuminating the sealing label with ultraviolet radiation and by observing whether the level of luminescence from the package material under the sealing label is lower than a limit value.

The anti-counterfeiting structure includes an allochroic layer including an allochroic part having a characteristic of changing from a first material to a second material in response to laser irradiation, a first layer transmissible to a laser beam, a second layer transmissible to the laser beam, at least a part of the second layer being located between the allochroic layer and the first layer, and a coating layer transmissible to the laser beam and covering at least the first layer. The coating layer and the first layer are bonded together more weakly than the first layer and the second layer are. One of the first layer and the second layer is a foamable layer having a characteristic of changing from an unfoamed state to a foamed state in response to laser irradiation, while the other of the first layer and the second layer is an optical device.

A chemical gas phase deposition process comprises steps of providing a high vacuum chamber, and inside the high vacuum chamber: positioning a substrate surface; positioning a mask parallel to the substrate surface, whereby the mask comprises one or more openings; adjusting a gap of determined dimension between the substrate surface and the mask; and orienting a plurality of chemical precursor beams of at least one precursor species towards the mask with line of sight propagation, each of the plurality of chemical precursor beams being emitted from an independent punctual source, and molecules of the chemical precursor pass through the one or more mask openings to impinge onto the substrate surface for deposition thereon. At least a part of the chemical precursor molecules decompose on the substrate surface at a decomposition temperature. The process further comprises adjusting a temperature of the substrate surface greater or equal to the chemical precursor molecule decomposition temperature, thereby remaining greater than a mask temperature, and maintaining the mask temperature below the decomposition temperature, thereby causing a decomposition of the chemical precursor and a growth of a film on the substrate surface, but not on the mask; and heating the substrate surface using a heating device.

The invention relates to a seal containing a substrate which can be applied to an object to be sealed, so that said seal is changed when it is removed without authorization, wherein the substrate contains or comprises a polymer and/or a glass and at least one optical waveguide is arranged in the substrate, at least one first Bragg grating being arranged in said optical waveguide, wherein the substrate has a thickness of less than 200 m. The invention further relates to a system having a seal of this kind and having an evaluation device, and also to a sealing method.

A tamper seal includes an optical waveguide arranged to guide a propagating light-beam along a propagation direction. First and second portions of the tamper seal are configured to be arranged on first and second parts, respectively, which are movable relative to each other. The first portion has an input coupler arranged to couple incident light into the optical waveguide, and the second portion has at least one output coupler arranged to couple out of the optical waveguide at least partially light guided in the optical waveguide. The input coupler, the optical waveguide, and the output coupler are configured to transmit light from the input coupler to the output coupler. The waveguide is configured to be disruptable and includes a layer having a distinctive appearance that is changed in response to an at least partial disruption of said optical waveguide.

Systems and methods can secure freight container seals using electronic sensors. A hardened sensor clamp housing can include one or more sensing portals. The sensor clamp housing can receive a bolt seal through each of the sensing portals. One or more seal sensors may be positioned proximate to the sensing portals to sense a physical characteristic of the inserted bolt seal. This characteristic may be electrical, optical, magnetic, or so forth. The seal sensors can generate an electrical signal associated with cutting or tampering with the inserted bolt seal. The electrical signal can be coupled to a sensor clamp module operable to determine a tamper state of the bolt seal in response to the associated electrical signal. The determined tamper state can be communicated via a sensor clamp wireless module to a container controller or communications gateway.

A printed image is disclosed wherein the image may be in the form of an array of magnetically aligned platelets or flakes that may by uniform in shape and size and wherein the flakes are arranged in a particularly manner to form optically illusive images useful as security devices, or useful in beam steering applications. In one embodiment of this invention printed array is disclosed a plurality of concentric rings of magnetically aligned platelets disposed upon a substrate in the form of a Fresnel structure, preferably a Fresnel reflector. Advantageously, since the magnetic field can be controlled with respect to strength and direction, one can easily design a field that will correct for spherical aberration that would otherwise be present in a typical Fresnel reflector. In other embodiments of the invention optically illusive images of funnels, domes and cones are printed.

The present disclosure is directed to pharmaceutical packages, such as syringes, vials, etc., containing wave-shifting crystals that, when excited, emit light having one or more characteristics by which information about the package, such as a unique package identifier, may be obtained. The wave-shifting crystals may be rare earth doped crystals. In some embodiments, the wave-shifting crystals may be incorporated into or onto a wall of a vessel, e.g. a syringe barrel or vial, in a way that maintains transparency of the vessel wall. In other embodiments, the wave-shifting crystals may be incorporated into or onto a portion of the package that need not be transparent, such as a needle shield, tip cap, or vial closure. The wave-shifting crystals may be used to track and/or authenticate a pharmaceutical package.

The disclosed embodiments include a method for tamper-proof protection of containers used for shipment of goods. The system contains a lock with electronic and mechanical components and a controller. A sensor is connected to a lock so that if forms a closed loop. The sensor can be an optical fiber or a distributed arrangement with an optical or an electrical shield. The electronics in the lock provide real time monitoring of the status of the lock. The lock cannot be opened or reproduced due to the signature of the closed loop which is stored in a remote server. Intrusions detected are relayed to an authorized recipient via a variety of communication channels. The data and control of the entire system is protected with several programs targeted to provide cybersecurity.

This invention is referred to a guarantee seal for non-opening electrical energy consumption meters with mechanical seal type padlock, disposable of a single use; for sealing or closing some container, box, door, cabinet, meter, valve, pump, bag, carrier bag, water tank, etc., meanly used for the electricity meters commonly used in countries of North America, Central and South America; whose purpose is protecting and controlling the electricity theft, guarantying its immobility.

Such guarantee seal has a unique shape that fits exactly with the cavities of the meters and it gets in by pressure, therefore if the seal is located outside of such cavity its external manipulation is evident, furthermore, it has a lid, a base, a verification system by continuity and tag or RFID tag to ensure the integrity of such seal.
