Abstract: Techniques for removing distortion in an AC magnetic tracker identify a characteristic frequency in the distortion environment which is then utilized to extract distortion components from the tracker receiver signals so that the corrected position and orientation can be calculated. A multiplicity of alternative techniques for determining this characteristic frequency are disclosed, several of which can be done during operation without interrupting system operation while others can be done off-line. The invention also allows the use of a tuned tracker transmitter since it does not need to operate at multiple frequencies. The invention differs from the prior art by treating an extended conductor characteristic as just another unknown. The position and orientation algorithm solves the 6 unknown coordinates of position and orientation plus the one more unknown—the extended conductor characteristic frequency.

Abstract: A system and method of multi-frame sampling for statistical analysis employs an estimator that may be generalize to two or more overlapping sampling frames. The estimator is accurate and requires less information and may be implemented more efficiently than previously known systems and methods. A generic computer system may be programmed to implement and employ the multi-frame sampling algorithms of the invention. Such algorithms may be employed to perform a statistical analysis on sample population data from multiple sample frames as stored in one or more databases accessible by the computer system.

Abstract: An electromagnetic field analyzer includes a division-into-element portion that divides form data as an analysis object into coarse elements and fine elements. A prolongation matrix forming portion forms a prolongation matrix defining an electromagnetic field vector of the coarse elements divided by the division-into-element portion related to an electromagnetic field vector of the fine elements. Then, an approximate value calculation portion and an approximate solution correction portion calculate an approximate solution of the electromagnetic field vector of the fine elements by applying an iteration method of simultaneous linear equations while referring to the prolongation matrix. Accordingly, it becomes possible to perform an electromagnetic field analysis at high speed by using a multi-grid method using a non-nested mesh.

Abstract: An electronic flow measurement device (EFM), for use in conjunction with a flow meter in a pressurized gas line, has a microprocessor and read-only memory (ROM), and calculates and records gas flow rates corrected for variable factors such as gas pressure, temperature, and density. Look-up tables stored in the ROM contain intermediate values calculated in accordance with selected protocols for selected ranges of input variables such as gas temperature, pressure, density, and turbine “K” factors. Based on inputs received from gas temperature and pressure sensors, the EFM selects corresponding intermediate values from the look-up tables, and then uses these values to calculate corrected gas flow rates, using software residing in the EFM. The microprocessor's power consumption is significantly reduced because the use of look-up tables reduces the complexity and extent of calculations that the EFM needs to perform, as compared with performing all required calculations in the EFM.

Abstract: A system and method for correcting a meter calibration curve in a fuel dispenser. The meter may be a turbine flow meter. A meter calibration curve is expressed in a finite number of data points. The meter calibration curve is used to determine the volume and/or flow rate of liquid flowing through the meter. Since the meter calibration curve may contain errors, the meter calibration curve is corrected by determining poles in the meter calibration curve for given known flow rates and/or volumes of liquid passing through the meter, determining an error correction at each of the poles in the meter calibration curve, correcting the expanded meter calibration curve at each of the poles, using linear interpolation to correct points in the meter calibration curve adjacent to the poles.

Abstract: The present invention provides a method of inspecting a target component part (e.g., valve casing) of an apparatus (e.g., steam control valve) included in a steam turbine system. When a time period in a range of 24 to 100 hours passes from the shutting-down of the turbine system, or before a temperature of an atmosphere surrounding the component part is lowered to 100° C., the width of the opening of the crack formed in the component part or a clearance relating to the component part is measured without disassembling the target component part and an enclosing member (e.g., valve casing) from the apparatus. As the measurement is performed when a thermal stress is induced in the component parts or when the temperature distribution is wide, the risk level of the crack or the clearance is determined accurately.
