  • Patent number: 10261034
    Abstract: A heat flow distribution measurement device includes a sensor module having one multilayer substrate and a plurality of heat flow sensor portions arranged inside of the multilayer substrate. The multilayer substrate has one surface and another surface opposite to the one surface and includes a plurality of stacked insulating layers each formed of a thermoplastic resin. The heat flow sensor portions are each formed of thermoelectric conversion elements and are thermoelectrically independent. An arithmetic portion arithmetically determines a heat flow distribution based on an electromotive force generated in each of the heat flow sensor portions. The thermoelectric conversion elements are formed in the multilayer substrate and therefore manufactured by the same manufacturing process for manufacturing the multilayer substrate. This can minimize the performance difference between the individual thermoelectric conversion elements and allow the heat flow distribution to be measured with high precision.

    Abstract: Devices and corresponding methods can be provided to monitor or measure temperature of a target or to control a process. Targets can have low, unknown, or variable emissivity. Devices and corresponding methods can be used to measure temperatures of thin film, partially transparent, or opaque targets, as well as targets not filling a sensor's field of view. Temperature measurements can be made independent of emissivity of a target surface by, for example, inserting a target between a thermopile sensor and a background surface maintained at substantially the same temperature as the thermopile sensor. In embodiment devices and methods, a sensor temperature can be controlled to match a target temperature by minimizing or zeroing a net heat flux at the sensor, as derived from a sensor output signal. Alternatively, a target temperature can be controlled to minimize the heat flux.

  • Patent number: 7226488
    Abstract: The present invention is directed to an apparatus and process for heating and cooling semiconductor wafers in thermal processing chambers. In particular, the apparatus of the present invention includes a cooling device for actively cooling the wafers after the wafers have been heated. During use, the cooling device can be movable towards and away from a wafer placed in the chamber for selectively cooling the wafer at desired times. In an alternative embodiment, a gas can be directed towards the wafer for rapidly reducing the temperature of the wafer at the completion of the process. Alternatively, the wafer can be lowered to close proximity of a cooling member to achieve active and selective cooling.

  • Patent number: 7119334
    Abstract: Systems and methods for thermal sensing and imaging using the electro-optic effect. A thermal detection system comprises a temperature sensing element that includes an electro-optic (EO) material layer having a length axis and characterized by a temperature dependent index of refraction, an electrical mechanism for inducing a chance in the index of refraction, a laser beam propagating lengthwise through EO layer for probing the refraction index change, and a light intensity meter for measuring a laser beam intensity change caused by the temperature dependent refraction index change. Thermal imaging is obtained by using a pixel array of such thermal sensing elements. The intensity reading may be done in either a cross-polarizer or a Mach Zehnder Interferometry reading configuration.

  • Patent number: 7052180
    Abstract: An instrument measures the LED junction temperature directly by taking advantage of the linear relationship between the forward current driven through the LED, the forward drop of the LED, and the junction temperature to determine the LED junction temperature. Calibration is conducted by placing two LEDs from the same family in ambient temperature and passing a small test current through each of the LEDs to obtain the forward drop of the LED at ambient temperature. The LED under test is then placed in an environmentally-controlled chamber where the temperature is raised a known amount above ambient temperature. Known low and high voltage values are associated with the ambient temperature and the environmental chamber temperature, causing the LED under test becomes a calibrated thermometer that can measure its own junction temperature due to the linear relationship between the forward drop and the junction temperature.

  • Patent number: 7014358
    Abstract: The invention relates to an infrared thermometer, especially an ear thermometer for measuring temperature, comprising an infrared sensor, a measuring tip which can be heated by a heating element, an actuating device which can be operated by a user, a control device and a display device. The invention also relates to a method for measuring temperature, especially by means of a radiation thermometer having a heatable measuring tip. Said control device switches off the heating element after the user has actuated an actuating device. After a certain amount of time, multiple temperature measurements are successively carried out, and the temperature to be displayed is determined from said measured temperatures or an error message is generated. At the latest, after a maximum measuring time has elapsed or after a maximum number of temperatures have been measured, the temperature to be displayed or an error message is displayed on the display device.

  • Patent number: 6964515
    Abstract: A temperature determining device is composed of a temperature detecting unit that detects a temperature of a determination object member based on an intensity of infrared rays from the object member, a unit for determining a temperature for correction that determines a temperature of an opposing member opposed to the object member or a temperature of a member whose temperature changes in correlation to a change in the temperature of the opposing member, and a calculating unit that corrects the detected temperature obtained by the temperature detecting unit using the temperature as the temperature for correction obtained by the unit for determining a temperature for correction. Thus, stable temperature determination can be performed accurately without being influenced by infrared rays from around a determination object member.
