    Abstract: A dual heat-freeze indicator and methods for making the same are disclosed. The dual heat-freeze exposure indicator includes a substrate, a low temperature indicator material provided in a first initial color state, a high temperature indicator material provided in a second initial color state, both supported by the substrate. The low temperature indicator material is configured to change from the first initial color state to a first exposed color state responsive to the indicator being exposed to a temperature below a low temperature threshold. The high temperature indicator material is configured to irreversibly change from the second initial color state to a second exposed color state responsive to the indicator being exposed to a temperature above a high temperature threshold. The low temperature indicator material returns from the exposed color state to the initial color state responsive to being exposed to a temperature above a reset temperature threshold.

    Abstract: A secure indicator includes a substrate, a barcode symbol that has a plurality of barcode modules provided on the substrate, and a security material positioned proximate the barcode symbol on the substrate. The security material is configured to be activated by irradiation at one or more predetermined activation wavelengths. Additionally, the barcode symbol is configured to be read (i) before the security material is activated and (ii) while the security material is activated.

    CPC classification number: G01K11/16

    Abstract: An apparatus, system, and method for producing a temperature exposure indicator is disclosed. The temperature exposure indicator includes a substrate and a mixture containing a first thermochromic material and a second thermochromic material. Each thermochromic material has an initial color state when the mixture is in a base temperature range and each thermochromic material is configured to change to an excursion color state at a certain temperature threshold. As a result, the mixture displays a low mixture excursion color state below a low temperature threshold and a high mixture excursion color state above a high temperature threshold.

    Abstract: An excess heat exposure indicator and methods for making the same are disclosed. The excess heat exposure indicator includes a print media substrate comprising an indicator region, a data region, at least one first thermochromic composition is provided on the substrate within the indicator region of the substrate, a second thermochromic composition is provided on the substrate within the data region, the second thermochromic composition configured to change color state from a third color state to a fourth color state when heated above a second temperature threshold, the indicator region is configured to be selectively treated with heat above the first temperature threshold to place a first portion of the indicator region in the second color state, different than the first color state, forming a visible indicia, the visible indicia configured to change appearance when the indicator region is subsequently exposed to a temperature above the first temperature threshold.
