20110012625 | ZINC OXIDE SULFUR SENSOR - Sulfur sensors are formed by coating a conductive substrate with ZnO microstructures that are reactive with sulfur in liquids, such as fuel, using MOCVD. The ZnO is changed to ZnS over time and causes the voltage across the sensors to change under a constant current by at least about 25%. The time required for such saturation to occur can then be correlated to a sulfur concentration in the liquid. | 01-20-2011 |
20120174656 | Zinc Oxide Sulfur Sensor Measurement System - A measurement system is disclosed for determining a sulfur concentration in a liquid, such as a liquid fuel. The measurement system includes a first electrode that is at least partially coated with zinc oxide and, more specifically, zinc oxide microstructures. The zinc oxide microstructures have a crystal lattice structure that is oriented in the (002) plane. The first electrode may be connected to an electrometer which, in turn, may be connected to a second electrode. The second electrode may be disposed on a common substrate with the first electrode or may be in the form of a plate disposed substantially parallel to the first electrode. | 07-12-2012 |
20120192626 | Zinc Oxide Sulfur Sensors and Methods of Manufacture Thereof - A sensor is disclosed for determining a sulfur concentration in a liquid, such as a liquid fuel. The sensor includes a substrate that is at least partially coated with zinc oxide and, more specifically, zinc oxide microstructures. The zinc oxide microstructures have a crystal lattice structure that is oriented in the (002) plane, are oxygen-deficient and have a rod-like microstructure. If the substrate is conductive, it may be connected directly to a working electrode which is connected to a potentiometer which, in turn, is connected to a reference electrode. If the substrate is non-conductive, the conductive layer can be deposited on the substrate prior to deposition of the zinc oxide to form a working electrode. An application of a constant current (or voltage) to either electrode will result in a voltage across (or current flow between) the working and reference electrodes. | 08-02-2012 |
20130132012 | EDDY CURRENT BASED METHOD FOR COATING THICKNESS MEASUREMENT - A method of configuring an eddy current detector to measure a thickness of a coating on a substrate includes measuring an impedance of the coated substrate, and establishing an impendence plane plot using a computer. The method may also include determining a rotation angle. The rotation angle may be an angle of rotation of the impedance plane plot that will make the inductive reactance component of the impedance substantially insensitive to substrate electrical conductivity within a coating thickness range. The method may further include establishing a calibration curve that is substantially insensitive to substrate electrical conductivity using the rotation angle. The calibration curve may be a curve that relates the inductive reactance component of the impedance to coating thickness. | 05-23-2013 |
20130272889 | Method of Extending the Service Life of Used Turbocharger Compressor Wheels - A method is provided for extending the service life of a used metallic compressor wheel having a damaged surface. The method generally comprises the steps of inspecting the used compressor wheel for material discontinuities such as fatigue cracks and, if fatigue cracks exceeding a predetermined length are not present, renewing the used compressor wheel such as by peening. The inspection process comprises conducting a non-destructive examination of the used compressor wheel to detect cracks larger than those which would fall generally within the compressive stress zone that is generated by peening. | 10-17-2013 |

The priority field of the received event registration is examined to determine priority of the received event registration. If the browser core is loading the response URI content of a prior event registration and if the priority of the received event registration is higher than the priority of the prior event registration, then the loading of the response URI content of the prior event registration is halted, and loading of the response URI content of the received event registration is begun. | 06-25-2009 |
20100132433 | Precision approach path indicator field testing instrument - The Field Testing Instrument (FTI) is designed for use in the regular maintenance and installation of airport Precision Approach Path Indicator (PAPI). The FTI is a self-contained and portable instrument that accurately measures the most important PAPI parameters, such as vertical aiming angle, transition angle, and light intensity. In addition to working with the current incandescent PAPIs, the FTI also measures parameters specific to the next generation LED PAPI. The FTI uses modern, efficient technology to reduce the life-cycle cost of approach lighting systems. The FTI improves on traditional PAPI testing methods by directly measuring the PAPI light beam focused to a target plate, as if seen from the pilot perspective. Due to significantly improvements in measurement accuracy and reliability, the FTI may supplement and even replace costly flight checks for PAPI maintenance with ground based operation. | 06-03-2010 |

20080262353 | METHOD AND APPARATUS FOR FAST VOLUME RENDERING OF 3D ULTRASOUND IMAGE - The invention provides a method and apparatus for fast volume rendering of 3D ultrasound image, comprising a dividing step, a calculating step, a determining step, a morphological closing operation step and a filling step, wherein each flat grid can be entirely filled by obtaining gray-scale values for all pixels inside the grid through interpolating; for the non-flat grid, the steps of dividing, calculating, determining and filling are performed repeatedly until the non-flat grid is subdivided into atomic grids to calculate gray-scale values for remaining pixels by projection. As the method can be finished in the rear end, no difficulty occurs in the implementation, and no process for being adapted to previous frames is required. Therefore, the method can improve the rendering speed effectively without degrading the quality of image to put 3D ultrasound imaging to the best use. | 10-23-2008 |
20080262355 | METHOD AND APPARATUS FOR FAST 3D ULTRASOUND IMAGING - The present invention provides a method and apparatus for fast 3D ultrasound imaging. The method comprises data acquisition, desired data selection, data smoothing, table construction, ray casting, table look-up, ray synthesis and final result output.
