Publication number: 20110051775Abstract: The present invention, in one embodiment, provides a method of measuring pressure or temperature using a sensor including a sensor element composed of a plurality of carbon nanotubes. In one example, the resistance of the plurality of carbon nanotubes is measured in response to the application of temperature or pressure. The changes in resistance are then recorded and correlated to temperature or pressure. In one embodiment, the present invention provides for independent measurement of pressure or temperature using the sensors disclosed herein.Type: ApplicationFiled: August 26, 2009Publication date: March 3, 2011Applicant: UT-BATTELLE, LLCInventors: Ilia N. Ivanov, David Bruce Geohegan

Bidirectional and expandable heat flow measurement tool for units of air cooled electrical equipment
Patent number: 7854547Abstract: A tool is disclosed, for measuring the important thermal characteristics of a unit of electronic equipment, which obtains air flow and temperature readings at both air inlet and air outlet openings of the unit without disturbing cable or wiring connections or otherwise interrupting device operation. The tool pressure sensing element is rotatable between detented positions to permit the tool to be used at both air inlet and air outlet openings. The tool air duct portion may be formed of separate duct portions to enable a single duct portion including the sensing instrumentation to be used with multiple duct portions that conform to electronic device air inlet and outlet openings to impart added flexibility to the tool.Type: GrantFiled: August 7, 2007Date of Patent: December 21, 2010Assignee: International Business Machines CorporationInventors: Alan Claassen, Dennis Hansen, Cary Huettner, Madhusudan Iyengar, Roger Schmidt, Kenneth Schneebeli, Gerard Weber, Jr. -
Publication number: 20100309604Abstract: 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.Type: ApplicationFiled: August 17, 2010Publication date: December 9, 2010Applicant: Lam Research CorporationInventors: Keith William Gaff, Neil Martin Paul Benjamin

Patent number: 7828477Abstract: A total air temperature probe includes an inlet through which airflow enters a primary airflow passage through the probe. A sensor flow passage is connected to the primary flow passage. Bleed ports extend between the primary airflow passage and a cross-port which extends laterally across the probe. An aspiration aperture in the cross-port couples the cross-port to an internal cavity of a strut of the probe. The aspiration aperture can be centered within the cross-port to provide symmetrical deicing heater error behavior of the probe during changes in angle of attack. An aspiration tube couples the internal cavity of the probe to a pressure source.Type: GrantFiled: May 14, 2007Date of Patent: November 9, 2010Assignee: Rosemount Aerospace Inc.Inventors: Kevin J.
