20110253677 | METHOD AND APPARATUS FOR PREHEATING IN WELDING OPERATIONS - Apparatus for pre-heating tubular articles prior to welding and a method of using the apparatus are disclosed. The apparatus comprises a support for carrying tubular articles such that they can be rotated together about long axis of the articles. A heater has a heating head that can be placed adjacent a region to be welded. The articles can be rotated so the region to be welded passes the heating head and is thereby heated to enable it to be welded subsequently. The heater is typically an induction heater. The method of welding tubular articles comprises mounting the articles in the support of a pre-heating apparatus of a welding installation embodying the invention and rotating the articles such that a weld region passes adjacent to the heating head. Then a part of the weld region is welded after it has rotated past and has been heated by the heating head. | 10-20-2011 |

20090323989 | System and method for calibrating an audiometer signal - A system and method for providing a translated or calibrated signal to a bone conduction transducer. The frequency of an audiometer output signal is detected and attenuation and amplification calibration values may be determined from a lookup table as a function of this frequency. Characteristics of the output signal may then be varied as a function of the calibration values to provide a translated or calibrated signal. This signal may then be provided to an exemplary bone conduction transducer such as a piezoelectric, electrostrictive or other electroactive bone conduction transducer. | 12-31-2009 |

20090090163 | WHEEL MEASUREMENT SYSTEMS AND METHODS - An improved maintenance, inspection, and/or measurement solution is provided. An embodiment of the invention includes a handheld measurement device for measuring an object, such as a railway wheel on a train. The handheld measurement device can comprise a single unit to provide one handed operation and can include various features, such as onboard evaluation, a graphical user interface, and/or a self-health monitor. Additionally, aspects of the invention provide an inspection environment that incorporates preliminary measurement data, wireless communications, and/or historical data into the measurement and evaluation process. | 04-09-2009 |
20090207420 | PORTABLE ELECTRONIC MEASUREMENT - The invention provides a handheld electronic gauge that is configured to obtain measurement data for an object, such as a wheel, rail, axle, or the like. The gauge includes one or more position sensors that automatically determine when the gauge is in a measurement position. The invention also provides a handheld computing device that can automatically determine when a gauge is in the measurement position and automatically obtain measurement data using the gauge. As a result, the invention provides a solution for measuring an object, such as a railway wheel, that is portable and capable of repeatedly providing various desired measurements, irrespective of the operator. | 08-20-2009 |
