| 20100137473 | AQUEOUS RESIN COMPOSITIONS AND METHODS FOR CEMENT REPAIR - A composition for repairing voids or cracks in a cement sheath or plug comprises an aqueous epoxy resin, a hardener, an alkali-swellable material and an aqueous carrier fluid. The particle size of the alkali-swellable material is preferably smaller than 200 nanometers, thereby allowing the composition to penetrate cracks as small as 60 micrometers. A method for repairing voids or cracks in a cement sheath, thereby restoring zonal isolation, comprises preparing the composition, injecting the composition into voids or cracks in a cement sheath or plug and allowing the composition to viscosify and harden. | 06-03-2010 |
| 20100258310 | COMPOSITIONS AND METHODS FOR SERVICING SUBTERRANEAN WELLS - This invention relates to methods for servicing subterranean wells, in particular, fluid compositions and methods for remedial operations during which the fluid compositions are pumped into a wellbore and make contact with well cements placed during primary cementing or previous remedial cementing operations. | 10-14-2010 |
| 20100270016 | Compositions and Methods for Servicing Subterranean Wells - This invention relates to methods for servicing subterranean wells, in particular, fluid compositions and methods for remedial operations during which the fluid compositions are pumped into a wellbore and make contact with well cements placed during primary cementing or previous remedial cementing operations. | 10-28-2010 |
| 20100307750 | SQUEEZE COMPOSITION FOR RESTORING ISOLATION - The invention discloses a method of treating a wellbore, comprising the step mixing an alkali swellable polymer and a first material, wherein said first material does not cause said alkali swellable polymer to swell significantly; and placing said alkali swellable polymer and said first material in the wellbore. | 12-09-2010 |
| 20120012318 | Compositions And Methods For Servicing Subterranean Wells - Fluid compositions comprising an aqueous epoxy resin, a hardener and particles comprising silica, aluminosilicate or both are useful for establishing hydraulic isolation in cemented subterranean wells. Upon entering voids and cracks in or adjacent to the cement sheath, and contacting the set-cement surfaces, the composition reacts and forms a seal that prevents further leakage. | 01-19-2012 |

| 20080266580 | Scaling methods for binary image data - The embodiments describe calculating and store scaling information based on processing input binary image data. By manipulating data that is received in binary format, the most cost effective method for scaling may be chosen. The input image data is scanned, a resolution (e.g., for display or output) is determined and a scaling method is determined. If the input binary image data needs to be scaled down to a smaller resolution, the binary image data is processed and scaled and then converted to grayscale image data. If the image data must be scaled to a larger resolution, the input binary image data is first converted to grayscale image data before processing using a segmentation tag-based scaling method. The scaled image data may then be output to an output device, such as a display, printer, or image output terminal. | 10-30-2008 |
| 20090161136 | COST EFFECTIVE IMAGE PATH FOR MULTIPLE OFFICE APPLICATIONS - A method and apparatus for configuring an image path of an image processing apparatus is herein described. The image processing apparatus includes at least an input terminal or scanner for inputting or scanning document into image data and an output terminal or printer for printing documents. The method includes selecting one of a plurality of output modes using a selection device associated with the image processing apparatus. Based on the selected output mode, an image path among a plurality of image processing elements of the apparatus is selected among a plurality of image paths. Each image path corresponds to one of the plurality of output modes. After a document is scanned with the scanner into image data, the image data is processed with the processing elements in the selected image path, and output or printed based on the processed image data. | 06-25-2009 |
| 20100110468 | SYSTEM AND METHOD FOR DIAGNOSING A FAILURE CONDITION IN AN IMAGE PATH OF AN IMAGE PROCESSING APPARATUS - Disclosed herein is a system and method for diagnosing a failure condition of an image processing apparatus. When a failure condition is detected in an image path during output of a document, a fault code is issued. The image processing apparatus is then capable of performing an internal diagnosis to generate a diagnostic report, and send the diagnostic report and fault code to an operator at a remote location. The system and method allows one to diagnose a problem or failure condition more quickly and efficiently, thereby cutting down on service time and costs. | 05-06-2010 |
| 20120014620 | BINARY REDUCTION WITH STRUCTURE PRESERVATION AND DENSITY CONTROL - A method for performing binary image reduction on binary image data includes receiving binary input image data; determining a conversion factor to scale (i) an input resolution to an output resolution and/or (ii) an input size to an output size; applying the conversion factor to the input image data to obtain intermediate data, where each intermediate data corresponds to at least one input pixel and at least a portion of another input pixel; obtaining a binary output image data comprising a plurality of output pixels by thresholding the corresponding intermediate data; determining an error value for each output pixel, the error value is a non-integer value obtained as a result of thresholding the intermediate data corresponding to the output pixel; and propagating the obtained error value to an adjacent output pixel in a scanline, where the output image data is scaled to the output resolution and/or the output size. | 01-19-2012 |
| 20120039534 | COMPRESSION SCHEME SELECTION BASED ON IMAGE DATA TYPE AND USER SELECTIONS - Disclosed is a processor-implemented method for processing image data comprising a plurality of pixels and system for performing the method. The method includes the following acts: determining at least one type of data represented by the plurality of pixels, determining, for each type of data, a number of pixels from the image data representing that type of data in the image data, and determining a compression scheme for compressing the image data based on a relative or absolute amount of each type of data in accordance with a predetermined scheme. The type of data may be determined by received input (e.g., user selected type and compression quality) or by analyzing its pixels and comparing it to thresholds. Basing the compression technique on the data type allows for better selection of a compression technique (e.g., MRC or JPEG), and thus greater image quality, compression ratios, and file size. | 02-16-2012 |
