  • Patent number: 10704962
    Abstract: The invention relates to devices for indicating the history of products, e.g., with regard to the temperature progression. The device according to the invention comprises a covering layer, an indicator layer, an activator layer, and an optional delaying layer. By means of heating, moisture is released, which, in the case of some embodiments, migrates first into the delaying layer and then into the activator layer. There, an activator is mobilized and migrates together with the moisture into the indicator layer. By interaction of the indicator with the activator in the presence of moisture, a color conversion occurs, which indicates the exceedance of the critical temperature. The invention further relates to methods for producing the device according to the invention and to applications of the device according to the invention, e.g., in the temperature monitoring of sensitive products.

  • Publication number: 20130081566
    Abstract: A release of the frozen solvent trapped inside a solidified gel occurs when the temperature increases, followed by a dissolving of a reactive substance present in a membrane that is located in direct physical contact with the gel, resulting in the reabsorption of the reactive substance dissolved in the solvent into the solid gel layer within a constant time. In this manner, the components generating color change come together within the solid gel layer initiating a reaction to change the color of the indicator layer. Thus, the increase in temperature above a melting point of the solid gel layer is enough to activate the intelligent label with an irreversible color change.

  • Patent number: 8354486
    Abstract: Solid polymerizable diacetylenic monomer compositions, including compositions co-crystallized from a diversity of solvent systems under diverse cooling conditions, can exhibit diffraction patterns associated with the color development reactivities of the compositions. High reactivity compositions are disclosed and high reactivity and low reactivity phases can be identified. A low angle powder X-ray diffraction peak can indicate the presence of one or more crystal phases in a composition. A fingerprint region can exhibit fingerprint patterns of diffraction peaks associated with different reactivities. Information about polymerization of the diacetylenic monomers is disclosed using 13C nuclear magnetic resonance (“NMR”) characterization. Diacetylenic monomer compositions useful in ambient condition indicators, for example time-temperature indicators are disclosed.

  • Publication number: 20120222610
    Abstract: Disclosed are an electromagnetic wave radiation detection member, an electromagnetic wave radiation detection method, and a device having the electromagnetic wave radiation detection member, which make it possible to determine whether or not the member has been heated by the electromagnetic wave radiation, such as a microwave oven. Specifically disclosed is an electromagnetic wave radiation detection member which is provided with a detection material (1) containing liquid and discoloring a substance to be adhered to which the detection material is adhered, and a bag (2) which includes the detection material (1) and from which the liquid flows out due to the radiation of the electromagnetic waves. As a result, the substance to be adhered is discolored by the electromagnetic wave radiation, thus making it possible to determine whether or not the electromagnetic waves have been radiated.

  • Publication number: 20120079981
    Abstract: A temperature-activatable time-temperature indicator that can be used to monitor the historical exposure of a host product to ambient temperatures includes an optically readable, thermally sensitive indicator element. The indicator element can be inactive below a base temperature and is intrinsically thermally responsive at or above an activation temperature which is equal to or greater than the base temperature. The indicator can record cumulative ambient temperature exposure above the activation temperature irreversibly with respect to time. The indicator element can include a synthetic polymeric material, and optionally, a dye. A side-chain crystallizable polymer such as poly(hexadecylmethacrylate), that is solid below the base temperature and is a viscous liquid above the activation temperature can be employed. Intense indicator element colors can be obtained using an appropriate dye or dyes. Various structural configurations of indicator are described and illustrated.

  • Publication number: 20120055393
    Abstract: An electronic part with a warning or a hiding effect substantially comprises an electronic part body, a predetermined position on a surface of which is coated with a temperature sensitive layer having a certain color. Heating the temperature sensitive layer when the heating temperature of the electronic part body soared to a predetermined temperature allows the temperature sensitive layer to be invisible. Thereby, the temperature sensitive layer presents to be wiped so as to achieve the warning and hiding effect.
