Abstract: An indicator composition for determining a thermal or chronological history during shipping or storage of a product. The composition includes a plurality of nanoparticles dispersed throughout a matrix. The nanoparticles turn color while dispersed in the matrix as a function at least one of time and temperature.

Abstract: An optical fiber temperature distribution measuring apparatus and a method for measuring optical fiber temperature distribution, provided with a light source for inputting a pulse light to an optical fiber to be measured, a signal detecting unit for detecting a received light intensity of a predetermined light included in a backscattering light generated by an input of the pulse light in the optical fiber to be measured, and a signal processing unit for calculating a value corresponding to a variation of the received light intensity due to a hydrogen molecular absorption of the optical fiber to be measured based on the received light intensity of the predetermined light, to compensate the received light intensity of the predetermined light corresponding to a temperature of the optical fiber to be measured based on the value.

Abstract: Thermochromic Temperature-Monitoring Clothing, is the first apparel invention to provide early detection and prevention of cold exposure to skin surface via thermochromism. The invention is comprised of various outerwear for adults, children, babies and/or infants which visibly displays dermal temperature by employing thermochromic color changing characteristics via thermochromic dye incorporated into the fabric of the apparel, and/or fabric affixed to the apparel at the extremities, and/or thermochromic device affixed to the apparel. Prior art related to thermochromic color change in apparel has been exclusively related to aesthetic considerations, and not for any perceived health benefits or for monitoring and communicating skin temperatures. Therefore, Thermochromic Temperature-Monitoring Clothing serves a useful purpose and satisfies a long neglected need in the area of apparel and health maintenance.

Abstract: Temperature-sensitive, color-changing inks, paints and resin concentrate additives are mixed into a child-resistant cap or lid to produce color changes indicative of its bottle having been recently opened and the medication within having been previously taken.

Abstract: Disclosed is a display apparatus including: a display panel which displays an image based on a video signal; a backlight unit which includes a plurality of light emitting diodes to emit a light to respective regions of the display panel; a sensor which senses a color temperature of the image which is displayed to the display panel; and a controller which transmits information about the color temperature sensed by the sensor to an external host apparatus and adjusts amount of current to be supplied to each light emitting diode on the basis of a result value corresponding to a target color temperature received from the external host apparatus. With this configuration, the color temperature is precisely adjusted regardless of deviation in products.

Abstract: A method of sensing high surface temperatures in aircraft applications is provided. The method includes the steps of applying a temperature indicator material on a surface an object in which monitoring exposure to high temperatures is sought. The temperature indicator material is reactive to a pre-determined temperature threshold. The temperature indicator material is next covered with a heat resistant film to protect the material during exposure to operating temperatures and deleterious environmental conditions. An identified visible change in the temperature indicator material provides confirmation of exposure of the surface of the object to temperatures in excess of the pre-determined temperature threshold.

Abstract: A system and method for a multi-temperature indicator stick. The multi-temperature indicator stick includes an elongated stick configured to indicate two or more predetermined temperatures. The elongated stick includes a first temperature indication material configured to indicate a first predetermined temperature upon being subjected to the first predetermined temperature. The elongated stick also includes a second temperature indication material configured to indicate a second predetermined temperature upon being subjected to the second predetermined temperature. The first temperature indication material and the second temperature indication material share a common interface extending longitudinally along the elongated stick.

Abstract: Disclosed is a defrost indicator that provides an irreversible indication that a frozen product has become thawed and unfrozen during any portion of time subsequent to its initial freezing. Also disclosed is a method for manufacturing a defrost indicator for frozen products. Further disclosed is a frozen product including a defrost indicator along with the frozen product packaging.
