20110010005SYSTEM FOR ASSOCIATING INVENTORY WITH HANDLING EQUIPMENT IN SHIPPING CONTAINER YARD INVENTORY TRANSACTIONS - A system is provided to associate containers with handling equipment (HE) in a container storage facility. In the system an operation detector, such as a twistlock sensor that indicates when a container is picked up or dropped off, is installed on a first HE which is a piece of container handling equipment (CHE) that can lift the container. An event detector, such as a vibration sensor or distance measuring radar, is further installed on a second HE that is a tractor with an attached chassis for receiving and transporting a container. The event detector indicates when a container-operation-related event, such as a container pick up or drop off, occurred on the tractor chassis. The two detectors (operation and event) are used by a processor to associate the container with either the CHE or the tractor. The operation and event detectors can further be used in conjunction with position sensors such as a GPS sensor to accurately determine the position of the tractor and the CHE in a container yard. When the position sensors degrade in performance, an additional motion detector such as a speed sensor can be used to determine the tractor's distance from the CHE to locate an appropriate tractor involved in the operation.01-13-2011

In each of the checking steps, the processor selects an error type from the list of error types, determines a search criterion based on the selected error type and the first data record, queries the database using the search criterion, compares query results with the first data record to detect data conflicts between them, and upon the detection of the data conflicts, reports that a data error of the selected error type has been detected.03-03-2011
20110055172AUTOMATIC ERROR CORRECTION FOR INVENTORY TRACKING AND MANAGEMENT SYSTEMS USED AT A SHIPPING CONTAINER YARD - A method automatically detects and corrects errors in a container inventory database associated with a container inventory tracking system of a container storage facility. A processor in the inventory tracking system performs a method to detect errors; this method of error detection obtains a first data record, identifies an event (e.g., pickup or drop-off of a container, or movement of handing equipment) associated with the first record, provides a list of error types based on the identified event, and determines whether a data error has occurred through a checking process. To correct the errors, this method further sets search criteria based on the error detection results, queries the inventory tracking database using the set criteria, determines error candidates based on the query results, evaluates the error candidates to identify a match or matches among the error candidates, and corrects the error(s) by modifying the error detection results together with the identified match or matches.03-03-2011

The apparatus comprises a primary illumination source, a catadioptric objective exhibiting central obscuration that directs light energy received from the primary illumination source at a substantially normal angle toward the specimen, and an optical device, such as a prism or reflective surface, positioned within the central obscuration resulting from the catadioptric objective for receiving further illumination from a secondary illumination source and diverting the further illumination to the specimen. The method comprises illuminating a surface of the specimen at a variety of angles using a primary illumination source, illuminating the surface using a secondary illumination source, the illuminating by the secondary illumination source occurring at a substantially normal angle of incidence; and imaging all reflected, scattered, and diffracted light energy received from the surface onto a detector.09-18-2008

20090080065Ultra-broadband UV microscope imaging system with wide range zoom capability - An ultra-broadband ultraviolet (UV) catadioptric imaging microscope system with wide-range zoom capability. The microscope system, which comprises a catadioptric lens group and a zooming tube lens group, has high optical resolution in the deep UV wavelengths, continuously adjustable magnification, and a high numerical aperture. The system integrates microscope modules such as objectives, tube lenses and zoom optics to reduce the number of components, and to simplify the system manufacturing process. The preferred embodiment offers excellent image quality across a very broad deep ultraviolet spectral range, combined with an all-refractive zooming tube lens. The zooming tube lens is modified to compensate for higher-order chromatic aberrations that would normally limit performance.03-26-2009

The plurality of TDI sensor modules can be positioned capture a same inspection region or different inspection regions. The plurality of TDI sensor modules can be identical or provide for different integration stages. Spacing of the modules can be arranged to provide 100% coverage of the inspection region in one pass or for fractional coverage requiring two or more passes for complete coverage.07-29-2010
20110073982Inspection system using back side illuminated linear sensor - An improved inspection system using back-side illuminated linear sensing for propagating charge through a sensor is provided. Focusing optics may be used with a back side illuminated linear sensor to inspect specimens, the back side illuminated linear sensor operating to advance an accumulated charge from one side of each pixel to the other side. The design comprises controlling voltage profiles across pixel gates from one side to the other side in order to advance charge between to a charge accumulation region. Controlling voltage profiles comprises attaching a continuous polysilicon gate across each pixel within a back side illuminated linear sensor array. Polysilicon gates and voltages applied thereto enable efficient electron advancement using a controlled voltage profile.03-31-2011
20110116077EUV High Throughput Inspection System For Defect Detection On Patterned EUV Masks, Mask Blanks, And Wafers - Inspection of EUV patterned masks, blank masks, and patterned wafers generated by EUV patterned masks requires high magnification and a large field of view at the image plane. An EUV inspection system can include a light source directed to an inspected surface, a detector for detecting light deflected from the inspected surface, and an optic configuration for directing the light from the inspected surface to the detector. In particular, the detector can include a plurality of sensor modules. Additionally, the optic configuration can include a plurality of mirrors that provide magnification of at least 100× within an optical path less than 5 meters long. In one embodiment, the optical path is approximately 2-3 meters long.05-19-2011
20110205529Cell For Light Source - A cell for a vacuum ultraviolet plasma light source, the cell having a closed sapphire tube containing at least one noble gas. Such a cell does not have a metal housing, metal-to-metal seals, or any other metal flanges or components, except for the electrodes (in some embodiments). In this manner, the cell is kept to a relatively small size, and exhibits a more uniform heating of the gas and cell than can be readily achieved with a hybridized metal/window cell design. These designs generally result in higher plasma temperatures (a brighter light source), shorter wavelength output, and lower optical noise due to fewer gas convection currents created between the hotter plasma regions and surrounding colder gases. These cells provide a greater amount of output with wavelengths in the vacuum ultraviolet range than do quartz or fused silica cells. These cells also produce continuous spectral emission well into the infrared range, making them a broadband light source.08-25-2011

20110164648Alleviation Of Laser-Induced Damage In Optical Materials By Suppression Of Transient Color Centers Formation And Control Of Phonon Population - Laser-induced damage in an optical material can be mitigated by creating conditions at which light absorption is minimized. Specifically, electrons populating defect energy levels of a band gap in an optical material can be promoted to the conduction band—a process commonly referred to as bleaching. Such bleaching can be accomplished using a predetermined wavelength that ensures minimum energy deposition into the material, ideally promoting electron to just inside the conduction band. In some cases phonon (i.e. thermal) excitation can also be used to achieve higher depopulation rates. In one embodiment, a bleaching light beam having a wavelength longer than that of the laser beam can be combined with the laser beam to depopulate the defect energy levels in the band gap. The bleaching light beam can be propagated in the same direction or intersect the laser beam.07-07-2011
