  • Publication number: 20110012625
    Abstract: 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.

  • Publication number: 20100132433
    Abstract: 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.

  • Publication number: 20080262353
    Abstract: 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.
