    Abstract: A system and method are provided for detecting fluid invasion of an annular space in a pipe structure. The system includes a thermal element and a temperature sensing element placed in the vicinity of each other in the annular space of the pipe structure. A thermal signal is generated by the thermal element. The temperature sensing element is connected to a monitor that monitors and processes the thermal signal. As the thermal signal changes when conducted through different types of fluids, the invasion of an annular space by seawater that normally contains oil or gas may be reliably detected.

  • Patent number: 8210741
    Abstract: An apparatus determines cooling characteristics of an operational cooling device used for transferring heat from an electronic device. The operational cooling device is thermally coupled to a heat pipe. The heat pipe has an exposed surface for selective application of heat thereon. Heat from a localized heat source is selectively applied to at least one region of the exposed surface. The heat source is preferably capable of being varied both positionally relative to the exposed surface and in heat intensity. A heat shield is preferably positioned around the exposed surface of the heat pipe to isolate the operational cooling device from the heat from the localized heat source. A temperature detector repeatedly measures a temperature distribution across the exposed surface while the cooling device is in a heat transfer mode. The temperature distribution is then used to thermally characterize the operational cooling device.

    Abstract: Methods and apparatus for wafer temperature measurement and calibration of temperature measurement devices may be based on determining the absorption of a layer in a semiconductor wafer. The absorption may be determined by directing light towards the wafer and measuring light reflected from the wafer from below the surface upon which the incident light impinges. Calibration wafers and measurement systems may be arranged and configured so that light reflected at predetermined angles to the wafer surface is measured and other light is not. Measurements may also be based on evaluating the degree of contrast in an image of a pattern in or on the wafer. Other measurements may utilize a determination of an optical path length within the wafer alongside a temperature determination based on reflected or transmitted light.

The subject materials or parts that are subjected to cryogenic temperatures approaching and below˜?300° F., ?184° C., 89° K, thereby causing permanent deformations or characteristic changes in the material if excessive residual stress, retained austenite or discontinuities exist. To determine the extent of changes, a first metric of the subject material is determined, the material is then subjected to cryogenic cooling thereby triggering any deformation or characteristic changes. Subsequent to the cryogenic cooling, the subject material may be returned to a second temperature whereby a second metric representing based on the same characteristic of the subject material is determined The comparison of the first and second metrics reveals the deformation or change resultant from the defect.

    Abstract: Wafer temperature is measured as a function of time following removal of a heat source to which the wafer is exposed. During the wafer temperature measurements, a gas is supplied at a substantially constant pressure at an interface between the wafer and a chuck upon which the wafer is supported. A chuck thermal characterization parameter value corresponding to the applied gas pressure is determined from the measured wafer temperature as a function of time. Wafer temperatures are measured for a number of applied gas pressures to generate a set of chuck thermal characterization parameter values as a function of gas pressure. A thermal calibration curve for the chuck is generated from the set of measured chuck thermal characterization parameter values and the corresponding gas pressures. The thermal calibration curve for the chuck can be used to tune the gas pressure to obtain a particular wafer temperature during a fabrication process.

  • Patent number: 7726874
    Abstract: A method and arrangement for determining the capacity of a heat exchanger is provided. The effective heat transfer coefficient for the heat exchanger is calculated from the measured inlet and outlet temperatures of the product and the measured inlet and outlet temperatures of the auxiliary medium. By means of the value, the outlet temperature of the product set for maximum flow of the auxiliary medium is determined as that at which the change in the heat content of the product is at least approximately the same as the change in the heat content of the auxiliary medium and the amount of heat transmitted by the heat exchanger for the product flow. The value is displayed to the user and permits a decision as to how much longer the heat exchanger can reliably be operated.

  • Publication number: 20100118912
    Abstract: A method of finding defects in sealing material formed as a frame line on a glass plate includes irradiating the frame line of sealing material. A temperature of the irradiated sealing material is measured and a change of the temperature caused by a nonuniformity in sealing material is detected. Another aspect features a method of hermetically sealing a thin film device between glass plates. Sealing material is dispensed on a cover glass plate in the form of a frame line cell. The sealing material is pre-sintered onto the cover glass plate and cooled. A laser beam is moved around the frame line on the sealing material. A temperature of the sealing material contacted with the laser beam is measured. A change in the temperature (?T) caused by a nonuniformity in the sealing material is measured. Further aspects include a feedback process, infrared imaging and use of delta temperature data to increase sensitivity of temperature measurement data.

  • Patent number: 7654734
    Abstract: A method for evaluating the thermal exposure of a selected metal component which has been exposed to changing temperature conditions is described. The voltage distribution on a surface of the metal component, or on a metallic layer which lies over the component, is first obtained. The voltage distribution usually results from a compositional change in the metal component. The voltage distribution is then compared to a thermal exposure-voltage model which expresses voltage distribution as a function of exposure time and exposure temperature for a reference standard corresponding to the metal component. In this manner, the thermal exposure of the selected component can be obtained. A related device for evaluating the thermal exposure of a selected metal component is also described.
