Patent number: 11487931Abstract: According to one embodiment, a method, computer system, and computer program product for webpage replay is provided. The embodiment may include acquiring one or more commands each indicating changes of at least one virtual Document Object Model (DOM) node of a virtual DOM of a webpage corresponding to a timestamp for a session. The embodiment may include determining one or more virtual DOM differentials corresponding to respective timestamps for the session based on the one or more commands and a first data dictionary. The first data dictionary is created based on a base virtual DOM of the webpage including a plurality of virtual DOM nodes. The embodiment may include generating one or more patched virtual DOMs of the webpage corresponding to respective timestamps for the session. The embodiment may include replaying the webpage for the session based on the base virtual DOM and the patched virtual DOMs.Type: GrantFiled: October 18, 2021Date of Patent: November 1, 2022Assignee: International Business Machines CorporationInventors: Wen Bao Yin, Jun Liao, Rui Shen, Dan Dan Wang, Shiwen He

Publication number: 20220304722Abstract: A medical device that cuts an object in a body lumen includes: a drive shaft; a shaft portion connected to the drive shaft; a cutting portion connected to the shaft portion; and first and second bearings that rotatably support the shaft portion. The first bearing has a ring shape, the second bearing has a ring shape and is spaced from a proximal side of the first bearing. The shaft portion includes a first sliding portion slidably supported by the first bearing, a second sliding portion slidably supported by the second bearing, and an intermediate portion between the first and second sliding portions. The intermediate portion has a protruding portion protruding radially outward, the protruding portion is disposed between the first bearing (81) and the second bearing in an axial direction, and the shaft portion has a passage that communicates from the first sliding portion to the second sliding portion).Type: ApplicationFiled: June 15, 2022Publication date: September 29, 2022Applicant: TERUMO KABUSHIKI KAISHAInventors: Taiga NAKANO, Kosuke NISHIO, Vivian TRAN, Dan BAO, Lam CANG

Patent number: 11440931Abstract: Provided are a series of crocins compounds and related pharmacological applications thereof in prevention and treatment of Alzheimer's disease. The series of crocins compounds are obtained by taking the Chinese herb, namely Gardenia jasminoides Ellis, as a raw material and separating same by means of various methods. The compounds playing a role in preventing oxidative injury caused by hydrogen peroxide (H2O2) and excitatory amino acid injury caused by L-glutamic acid are screened out by in-vitro cell experiments. The results show that the crocins compounds have good effect in preventing cell injury caused by H2O2 and L-glutamic acid. The compounds have good effect in preventing and treating Alzheimer's disease due to the fact that significant rise of oxidative stress and excitatory amino acid is a key factor for nerve injury in Alzheimer's disease, and have broad development and application prospect.Type: GrantFiled: March 16, 2017Date of Patent: September 13, 2022Assignee: Jinan UniversityInventors: Xinsheng Yao, Yang Yu, Dan Zhang, Yang Ni, Xiuqi Bao, Lin Li, CaixĂa Zang, Hao Gao, Yuanpeng Zheng

Publication number: 20210024498Abstract: The present invention discloses a tetrahydropyrrole compound, a preparation method therefor, a pharmaceutical composition containing the same, and a use thereof. The tetrahydropyrrole compound of the present invention is represented by general formula (I). The tetrahydropyrrole compound of the present invention has better inhibitory effects on the positive symptoms of schizophrenia, and the potency thereof is equivalent to or slightly stronger than that of the positive drug olanzapine. In addition, the compound of the present invention has dual inhibitory effects on D2 receptors and DAT receptors, and is effective for treating schizophrenia and improving negative symptoms and cognitive functions, while also reducing vertebral side effects and prolactin secretion.Type: ApplicationFiled: December 26, 2018Publication date: January 28, 2021Inventors: Zhu DANG, Christine Jue CAI, Zhen LUO, Liugang WANG, Dan BAO

Patent number: 9307904Abstract: An ophthalmic system for use in performing angular measurements in relation to a patient's eye. The ophthalmic system can include an optical angular measurement device that can provide angular indicia by, for example, projecting an image of an angular measurement reticle onto a patient's eye or by superimposing an image of an angular measurement reticle onto an image of the patient's eye. The ophthalmic system can include an optical refractive power measurement device for providing desired angular orientations for ocular implants or for incisions. The ophthalmic system can be used, for example, to align a toric intraocular lens to a desired angular orientation.Type: GrantFiled: October 4, 2013Date of Patent: April 12, 2016Assignee: WaveTec Vision Systems, Inc.Inventors: Thomas D. Padrick, Jack T. Holladay, Dan Bao Tran, Aric K. Plumley, Richard J. Michaels, Jeff Padgett

Patent number: 9231620Abstract: An iterative decoding device includes a decoder, a dual mode determination unit and a dual mode scaling unit. The decoder is utilized for receiving a set of soft information (SI) and iteratively decoding the set of SI and updating the set of SI accordingly to generate a set of updated SI. The dual mode determination unit is coupled to the decoder for generating a determination result according to the set of updated SI. The dual mode scaling unit is coupled to the dual mode determination unit and the decoder for scaling the set of updated SI according to the determination result to generate a set of scaled SI acting as an input of the decoder for next iteration.Type: GrantFiled: October 8, 2012Date of Patent: January 5, 2016Assignee: NOVATEK Microelectronics Corp.Inventors: Dan Bao, Dawei Deng, Song Qian, Bo Shen

Patent number: 8924821Abstract: A decoding method for low density parity check (LDPC) and an electric device using the decoding method are provided. The decoding method includes: receiving a message and executing an iteration decoding to the message; obtaining first belief values of the message in an (i?1)th iteration; obtaining a first energy summation of the first belief values; obtaining second belief values of the message in an ith iteration; obtaining a second energy summation of the second belief values; determining whether the second energy summation is smaller than the first energy summation and whether a difference between the first energy summation and the second energy summation is larger than a first threshold; if yes, generating a decoding result according to the first belief values. Therefore, a bit error rate of the decoding is decreased.Type: GrantFiled: February 21, 2013Date of Patent: December 30, 2014Assignees: Novatek (Shanghai) Co., Ltd., Novatek Microelectronics Corp.Inventors: Da-Wei Deng, Dan Bao, Zheng Li, Song Qian
