  • Patent number: 7780345
    Abstract: A method and apparatus for an irreversible temperature sensor for measuring a peak exposure temperature. The apparatus is fabricated by printing an admixture of conductive nanoparticles on a dielectric substrate to form a film. The film has an electrical resistance that is inversely proportional to the exposure temperature. The electrical resistance also irreversibly decreases as the exposure temperature of the film increases. A portion of the film is exposed to a pulse of electromagnetic energy sufficient to render it substantially more electrically conductive than the portion that was not exposed. In use, the peak exposure temperature is determined by measuring the electrical resistance of the non-altered portion of the film and the electrical resistance of the portion that was exposed to the pulse of electromagnetic energy, and subtracting the electrical resistance of the altered portion from the electrical resistance of the portion that was not altered, to provide a difference value.

  • Patent number: 7651268
    Abstract: The present invention is a non-invasive method and associated apparatus for determining the junction temperature for an LED or laser diode (collectively “LED”). First a sample LED is placed in a heat chamber and the change of the LED's peak wavelength is recorded over time, as is the change in the temperature in the heat chamber. Since the heat chamber supplies the major component to the junction temperature, dwarfing the other components, it is a reasonable proxy for true junction temperature. The data is compiled to determine change of peak wavelength as a function of temperature and that function can then be used to determine junction temperature of similar LEDs that are installed in a system or manufactured. The invention may also be used to measure other useful data, such as power, output power changing with the junction temperature and intensity of the LED over time and may be used to estimate failure rate.

  • Patent number: 6924148
    Abstract: A product shelf life monitoring system comprising an active substituted diacetylenic monomer component indicator composition is responsive to an integral of varying temperature over time to effect a solid state polymerization in the active monomer which results in a visible change in color density or the like at a rate designed to closely approximate the degradation, or shelf life, of an associated foodstuff or medicament product. The reactivity of the monomer component upon which the time-temperature integral of the indicator composition, and thus the represented shelf life, primarily depends may be readily varied by refluxing a solution of the monomer in a selected solvent for a predetermined time prior to recrystallization of the monomer for incorporation into the indicator composition.

  • Publication number: 20030198135
    Abstract: A temperature monitoring system and method for continuously monitoring the temperature of a material and providing a cumulative total time that the material has spent at a temperature above a predetermined temperature threshold over a given period of time or over the shelf life of the material. The apparatus 10 includes a temperature probe which provides an output to a temperature switch. The temperature switch provides an output therefrom to a cascaded counter array. An oscillator also provides an output to the counter array. The counter array maintains a cumulative count (i.e., cumulative time value) that the material has spent above a predetermined maximum temperature threshold. A battery powers the components of the apparatus and a display allows the user to display the cumulative time that the material has spent above the predetermined temperature threshold.

  • Patent number: 6042264
    Abstract: A time-temperature indicator label for measuring the length of time to which a product has been exposed to a temperature above a pre-determined temperature is provided. The period of time of exposure is integrated with the temperature to which the indicator is exposed. The label is a composite of a plurality of layers adapted to be adhered at its underside to a product container. The label includes a printable surface layer, a longitudinal wicking strip that is adhered underneath the surface layer substantially at the opposite extremities only of the wicking strip and a lower substrate layer forming an envelope with said surface layer. A heat-fusible substance, which melts and flows above a pre-determined temperature, is applied on the surface of the wicking strip contiguous to at least one of the ends of the wicking member. When the heat-fusible substance is exposed to a temperature above the pre-determined temperature, the heat-fusible substance flows along the length of the wicking member.
