A label sticker includes a release layer strip, an attachment layer strip and a label layer strip. The attachment layer strip is made of an artificial dressing material and its lower surface is coated with or adhered to a first glue layer. The lower surface of the attachment layer strip is attached to the upper surface of the release layer strip through the first glue layer. The label layer strip is made of a waterproof material and its lower surface is coated with or adhered to a second glue layer. The lower surface of the label layer strip is attached to the upper surface of the attachment layer strip through the second glue layer. The label sticker, to be adhered to the human skin to serve identification purposes, can be manufactured by mass production but is unlikely to be wetted and smeared.

An adhesive label includes: a printable front side which is non-opaque to IR radiation; an adhesive layer for sticking the label to an application medium, the adhesive force of the front side being less than the gripping force of the adhesive layer; and a compound exhibiting a certain behaviour when illuminated by the IR radiation through the front side, the electromagnetic response of the compound during the illumination by the IR radiation being detectable through the front side.

A method of marking a package (72) includes providing a package (72) including an additive transformable from a first state to a second state in response to an external stimulus and presenting said package via a sales device (80). At least a portion of said additive is in said first state when said package is presented in said sales device (80). At least a portion of said additive is activated to form identifying indicia on said package within said sales device (80).

An indicator is provided that can couple, without a fastener, to a housing of an industrial device.

The present invention relates to a smart and secure label stock with security features. The present invention relates to a label stock produced from a substrate utilizing adhesive and liner materials and having a plurality of security features on the rear side of the substrate made using specialized inks and various authentication features for different applications.

Provided herein is a label structure for tagging a product item. The label structure includes a first graphic pattern having a first number of pixels and printed on a first portion of the label structure; a second graphic pattern having a second number of pixels and printed on a second portion of the label structure, the second graphic pattern forming an optical code readable by an optical decoding device; and shielding means capable of hiding or making visible the first graphic pattern depending on the values taken by a physical quantity to which the label structure is exposed. The first and second graphic patterns can be observed in combination, when the first graphic pattern is made visible by the shielding means.

Disclosed embodiments may relate to a time-dependent color-changing label for a product. The label may include a first layer comprising a plurality of particles, the particles comprising a time dependent color-changing material that changes color after a predetermined time period, the predetermined time period being greater than one month. The label may also include an attachment structure attaching the first layer to the product. In certain embodiments, the first layer may include a polymer, and the particles may include glass microspheres containing the time-dependent color changing material. The particles may be embedded in the polymer.

The present invention relates to time temperature indicator (TTI) systems for monitoring the time and temperature exposure of foods, nutraceuticals, pharmaceuticals, chemicals and similar products. More particularly, the present invention provides a cap system, such as a screw cap system, featuring a TTI system.

A method of detecting temperature of an electrical terminal. The method includes: applying a material patch to a surface of the electrical terminal, the material patch containing a polymer matrix with a polymeric positive temperature coefficient material which contains a mixture of electrically conductive magnetic particles, whereby the material patch does not appreciably increase the electrical resistance or thermal capacitance of the electrical terminal; and remotely sensing a change in the material patch with an electrically isolated circuit which is external to the electrical terminal to determine if the electrical terminal is operating at a safe temperature to optimize current flow across the electrical terminal.

The present invention relates to a labeling element for items, which on a surface thereof is formed with a plurality of pixels with periodic lattice structures, in particular linear lattice structures. Lattice structures with in each case one structural period A and an alignment of the structural elements, which are aligned to one another in particular in a linear parallel manner, at an angle φ with respect to an axis of reference are formed in individual pixels such that when the pixels constituting the labeling element are irradiated with electromagnetic radiation, preferably monochromatic electromagnetic radiation, an image of the labeling element is created on an detector array or a surface, by means of images of at least one order of diffraction of the electromagnetic radiation diffracted by pixels which can be used for identification of the respective labeling element.
