Publication number: 20220375082Abstract: A diagnostic system to analyze imaging data includes a memory configured to store hybrid imaging data of a tissue sample. The system also includes a processor operatively coupled to the memory and configured to generate a four quadrant plot based on the hybrid imaging data. Each point in the four quadrant plot corresponds to an image voxel of the tissue sample. The processor is also configured to determine one or more angle values and one or more distance values for image voxels in the four quadrant plot. The processor is further configured to identify one or more characteristics of the tissue sample based at least in part on the one or more angle values and the one or more distance values. The processor is further configured to perform a matrix analysis of the data, which can be used to identify the one or more characteristics of the tissue sample.Type: ApplicationFiled: November 11, 2020Publication date: November 24, 2022Inventors: Aritrick Chatterjee, Gregory S.

Patent number: 10801132Abstract: A high uniformity coloured polyester industrial yarn and preparation method. The raw material of the high-uniformity coloured polyester industrial yard is the modified polyester composed of terephthalic acid segment, an ethylene glycol segment and a branched diol. The high-uniformity coloured polyester industrial yarn is prepared by esterification reaction of terephthalic acid with a branched diol using concentrated sulfuric acid as catalyst to obtain terephthalic acid glycol ester. Terephthalic acid and ethylene glycol are formulated to carry out esterification reaction to obtain ethylene terephthalate. Finally, stir and mix the two materials and carry out the polycondensation reaction in the low vacuum stage and the high vacuum stage under the action of the catalyst and the stabilizer to obtain modified polyester. Measure the modified polyester and add black masterbatch.Type: GrantFiled: June 26, 2017Date of Patent: October 13, 2020Assignee: JIANGSU HENGLI CHEMICAL FIBRE CO., LTD.Inventors: Hongwei Fan, Lili Wang, Xiaobing Fan, Damao Yang, Guangkun Song, Huirong Zhao, Shanshui Wang

Patent number: 10041192Abstract: The present invention discloses an ultra-low shrinkage polyester industrial yarn and its preparation method. The ultra-low shrinkage polyester industrial yarn is prepared by subjecting a polyester to dissolution, washing and solid state polycondensation followed by spinning. The ultra-low shrinkage polyester industrial yarn has a dry heat shrinkage rate of 1.8±0.25% under test conditions of 177° C.×10 min×0.05 cN/dtex. The polycondensation catalyst consists of magnesium ethylene glycol and antimony ethylene glycol, has a small thermal degradation coefficient. The present invention reduces oligomers during polymerization, reduces thermal degradation during processing, and as a result the invention greatly reduces impurities and nucleating agent in the polyester, leading to an increase in the probability of homogeneous nucleation based on the reduction of heterogeneous nucleation.Type: GrantFiled: October 25, 2016Date of Patent: August 7, 2018Assignee: JIANGSU HENGLI CHEMICAL FIBRE CO., LTD.Inventors: Huirong Zhao, Xiaobing Fan, Chaoming Yang, Lijun Wang

Patent number: 9972089Abstract: A computing device determines a contrast medium uptake time using magnetic resonance imaging data. Image data constructed from data generated by a magnetic resonance imaging (MRI) machine of a subject is read. A representation computed from the read image data is presented on a display device. Baseline artery locations identified within the presented representation that are associated with a baseline artery are received. A first time-of-arrival (TOA) of contrast medium into the baseline artery is determined using the received baseline artery locations and the read image data. For a plurality of locations within the read image data excluding the baseline artery locations, a second TOA of the contrast medium into a respective location relative to the determined first TOA is determined using the read image data, and the determined second TOA is stored in association with the respective location to assist in lesion identification for the subject.Type: GrantFiled: August 26, 2016Date of Patent: May 15, 2018Assignee: The University of ChicagoInventors: Gregory S.

Patent number: 9238944Abstract: This invention relates to a tri-cone bit for high RPM drilling applications, which comprises three head sections and three cones. Cutting elements are arranged on each cone. Upper parts of the three head sections are joined together to form a bit body, on which nozzle sockets are provided, and nozzles are installed in bores of the nozzle sockets. A bearing between the cones and the head sections is a composite roller-journal bearing which is formed by rollers and arc-shaped slides arranged in an alternating way, and a seal means for the bearing is of metal face type. The composite roller-journal bearing of the invention can withstand high RPM and high load, and also has a higher resistance to impact, thereby ensuring longer working life of the bearing under high RPM and medium-high WOB. The six-point gage protection structure enhances stability of the bit and reduces cutting element breakage caused by bit vibration.Type: GrantFiled: March 9, 2011Date of Patent: January 19, 2016Assignee: Kingdream Public Ltd.

Patent number: 8360175Abstract: This invention relates to carbide inserts used on roller cone bits for oil and gas drilling applications as well as for other geological drilling applications, and more specifically, relates to the convex crested insert with deflected wedge surfaces. The insert comprises a cylindrical portion and a crest portion. Said crest portion is composed of a conical crest base, a top surface and two opposing wedge surfaces. Upper ends of the two wedge surfaces are merged smoothly with top surface of the insert. The specific feature of the structure is that top surface of the crest portion is convexed outwardly and forms a smooth curve surface which is higher in the middle and lowers down gradually to each end. Said two wedge surfaces are slant wedge surfaces, so that a width of the top surface and therefore a width of the insert crest are tapered from one end to the other. Advantages of this invention include: 1.Type: GrantFiled: May 27, 2010Date of Patent: January 29, 2013Assignee: Kingdream Public Ltd. Co.Inventors: Xiaobing Fan, Peng Wu, Dongfang Chen, Chengfu Guo

Publication number: 20100032215Abstract: The present invention discloses a tri-cone drill bit comprising: three head sections with upper parts thereof jointed together to form a bit body, three cones rotatably mounted to lower ends of the head sections respectively, nozzle sockets designed on the bit body between respective head sections and each having a hole in which a nozzle is mounted, wherein gage cutters are mounted to an upper trailing side of each head O.D. surface to form a gage holding surface thereon, and a leading side of each head section is backwardly slanted as a whole. The design of gage surface at trailing sides of head sections increases the bit's stability, reduces lateral vibration and also reduces tendency of bit deflection in horizontal drilling applications and effective working life of the bit is improved. Backward slant of leading sides of head sections facilitates upward carrying of drilling cuttings and improves drilling efficiency.Type: ApplicationFiled: July 29, 2009Publication date: February 11, 2010Applicant: Kingdream Public Ltd.
