Patent number: 12338382Abstract: The present invention is directed to surfactants with small hydrophobes, which are of non-conventional hydrophobe size. The surfactants of the present invention utilize a small hydrophobic moiety with a polyalkoxylate chain comprising PO, BO and/or EO groups, with optional ionic groups, such as anionic, cationic and zwitterionic, to achieve the desired hydrophilic-lipophilic balance (HLB). The present invention is further directed to formulations comprising the surfactants of the invention, and methods of using the surfactants of the invention, including in enhanced oil recovery applications.Type: GrantFiled: April 4, 2018Date of Patent: June 24, 2025Assignee: Harcros Chemicals, Inc.Inventors: Upali Weerasooriya, Peter Radford, Kevin Sikkema, John Boorem, Aaron Boorem, Kurt Cheshire, Kishore K.

Publication number: 20040037475Abstract: Methods and systems for automated enhancement of annotated images while maintaining the pristine form of the annotations. The disclosed technique has application in processing of intensity or grayscale images as well as processing of color images. The method for processing a grayscale annotated image comprises the following steps: removing one or more annotations from the annotated image to derive a modified image; processing the modified image using an algorithm to derive a processed image; and merging the removed one or more annotations with the processed image to derive a merged image. In the case of RGB color annotated images, the RGB values are first converted into hue, saturation and value (HSV) components. Then the value (i.e., brightness) component of the resulting HSV image is processed using the disclosed technique.Type: ApplicationFiled: August 26, 2002Publication date: February 26, 2004Inventors: Gopal B.

Patent number: 6592523Abstract: In ultrasound imaging, acquired images are corrupted by slowly varying multiplicative non-uniformity. When the image is corrected for non-uniformity alone, noise in the dark regions of the original image becomes multiplicatively enhanced, thereby providing an unnatural look to the image. A pre-filtering technique is used to reduce noise in ultrasound pixel images by shrinking initial image data and processing the shrunken image with known segmentation-based filtering techniques that identify and differentially process structures within the image. The segmentation is based on both gradient threshold and the distance from the near field of the ultrasound image. This modification selectively suppresses near-field artifacts. After processing, the shrunken image is enlarged to the dimensions of the initial data and then blended with the initial image to form the final image.Type: GrantFiled: July 17, 2002Date of Patent: July 15, 2003Assignee: GE Medical Systems Global Technology Company, LLCInventors: Gopal B.

Publication number: 20030113005Abstract: The present invention aims at readily calculating a difference between the positions of a plurality of images. Noises are removed from a plurality of halftone images representing the same object. The plurality of halftone images having noises removed therefrom is binary-coded. The barycenters of the binary-coded images are specified. A difference between the positions of the plurality of halftone images in image frames is calculated based on a difference between the positions of the barycenters thereof in the image frames. The plurality of halftone images are synthesized with the difference between the positions of the halftone images in the image frames corrected.Type: ApplicationFiled: December 12, 2002Publication date: June 19, 2003Inventors: Amit Saxena, Pinaki Ghosh
