Patent number: 11931993Abstract: A bonding method and a bonding device for a flexible panel. In the process of bonding a protective cover plate and the flexible panel, a heated-type optical adhesive is used, the optical adhesive at normal temperature has relatively low viscosity and the viscosity thereof is below a bondable threshold, so that before the flexible panel and the edge of the protective cover plate are bonded, the optical adhesive and the edge of the protective cover plate come into contact in advance and then can be effectively separated, thus poor bonding in a bending region is avoided, the risk of generating bubbles and cracks is small, and the bonding yield can be improved. Moreover, the optical adhesive is increased in viscosity after heated, thereby ensuring that the flexible panel is bonded to the protective cover plate.Type: GrantFiled: February 2, 2021Date of Patent: March 19, 2024Assignees: CHENGDU BOE OPTOELECTRONICS TECHNOLOGY CO., LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Jia Deng, Jialin Wang, Rongkun Fan, Shengqiang Wu, Xue Meng, Yuanhong Wen, Senlin Ma, Chaoxue Qin, Peng Wang

Patent number: 6784162Abstract: A single point mutation in the human lipoprotein lipase gene which results in an A→G nucleotide change at codon 291 (nucleotide 1127) of the lipoprotein lipase gene, and a substitution of serine for the normal asparagine in the lipoprotein lipase gene product is seen with increased frequency in patients with coronary artery disease, and is associated with an increased susceptibility to coronary artery disease, including in particular premature atherosclerosis. This is expressed as a diminished catalytic activity of lipoprotein lipase, lower HDL-cholesterol levels and higher triglyceride levels. Thus, susceptibility of a human individual to premature atherosclerosis can be evaluated by: (a) obtaining a sample of DNA from the individual; and (b) evaluating the sample of DNA for the presence of nucleotides encoding a serine residue as amino acid 291 of the lipoprotein lipase gene product. The presence of a serine residue is indicative of increased susceptibility in the patient.Type: GrantFiled: July 10, 1997Date of Patent: August 31, 2004Assignee: The University of British ColumbiaInventors: Michael R. Hayden, Yuanhong Ma, Suzanne Lewis, Guoquing Liu

This is expressed as a diminished catalytic activity of lipoprotein lipase, lower HDL-cholesterol levels and higher triglyceride levels. Thus, susceptibility of a human individual to premature atherosclerosis and other forms of coronary artery disease can be evaluated byevaluating the sample of DNA for the presence of nucleotides encoding a serine residue as amino acid 291 of the lipoprotein lipase gene product. The presence of a serine residue is indicative of increased susceptibility in the patient.Type: GrantFiled: October 11, 1994Date of Patent: August 19, 1997Assignee: The University of British ColumbiaInventors: Michael R.
