Patent number: 7780345Abstract: 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.

Patent number: 7651268Abstract: 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.Type: GrantFiled: February 23, 2007Date of Patent: January 26, 2010Assignee: CAO Group, Inc.Inventors: Desen Cao, Zhao-hui Lin

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.Type: GrantFiled: July 2, 2003Date of Patent: August 2, 2005Assignee: TEMPTIME CorporationInventor: Thaddeus Prusik

Publication number: 20030198135Abstract: 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.Type: ApplicationFiled: April 19, 2002Publication date: October 23, 2003Inventors: John S.

Patent number: 6042264Abstract: 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.Type: GrantFiled: November 21, 1997Date of Patent: March 28, 2000Assignee: Lifelines Technology, Inc.Inventors: Thaddeus Prusik, Raymond M.
