Patent number: 11972826Abstract: Disclosed herein are related to a system and a method of extending a lifetime of a memory cell. In one aspect, a memory controller applies a first pulse having a first amplitude to the memory cell to write input data to the memory cell. In one aspect, the memory controller applies a second pulse having a second amplitude larger than the first amplitude to the memory cell to extend a lifetime of the memory cell. The memory cell may include a resistive memory device or a phase change random access memory device. In one aspect, the memory controller applies the second pulse to the memory cell to repair the memory cell in response to determining that the memory cell has failed. In one aspect, the memory controller periodically applies the second pulse to the memory cell to extend the lifetime of the memory cell before the memory cell fails.Type: GrantFiled: July 8, 2021Date of Patent: April 30, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Yung-Huei Lee, Pei-Chun Liao, Jian-Hong Lin, Dawei Heh, WenHsien Kuo

Patent number: 9549861Abstract: An early warning method and a device for preventing a wheelchair from tipping over are described. The early warning method includes projecting a laser light pattern, scanning the laser light pattern, making a comparison to determine whether the ground is a barrier terrain, and issuing an early warning to the user in situations of risk. The laser light pattern is projected onto the ground and compared with a standard pattern. The early warning is generated and is one selected from a group consisting of a beep, a warning message and a vibration to alert the wheelchair user to the danger of the barrier terrain.Type: GrantFiled: August 30, 2013Date of Patent: January 24, 2017Assignee: NATIONAL TAIWAN UNIVERSITYInventors: Shih-Chung Kang, Pei-Chun Lin, Yung-Shun Su, Ci-Jyun Liang, Pei-Yi Lee, Yao-Yu Yang, Kevin Lin, Chuan-En Lee

Publication number: 20150104440Abstract: The current disclosure reveals a complex regulatory pattern between miR-31 and AR, indicating that miR-31 plays a key role in prostate cancer development and progression. Another aspect of the current disclosure shows that miR-31 directly targets and destabilizes AR mRNA through interaction with the AR mRNA coding sequence showing that miR-31, or a fragment thereof has the ability to act as a novel therapeutic agent in treating cancer. The current disclosure also shows that AR indirectly represses miR-31 expression by binding to the miR-31 promoter region and modulating methyltransferase activity. Another aspect of the current disclosure shows that miR-31 indirectly modulates AR activity by modulating regulators of cell cycle progression. The disclosure further provides an isolated nucleic acid that modulates the activity of the androgen receptor in a cell.Type: ApplicationFiled: April 12, 2013Publication date: April 16, 2015Applicant: CORNELL UNIVERSITYInventors: Pei-Chun Lin, Mark A.

Patent number: 8372230Abstract: The invention concerns a method for making an article having a tunable adhesive, said method comprising applying strain to mechanically deform a substrate in at least one direction; applying a rigid coating layer on the substrate; and releasing the strain to form an article having a rippled surface. Ripple characteristics can be altered by mechanical strain in real time which further changes the adhesion properties.Type: GrantFiled: March 28, 2008Date of Patent: February 12, 2013Assignee: The Trustees Of The University Of PennsylvaniaInventors: Shu Yang, Pei-chun Lin

Patent number: 8307923Abstract: A mobile platform including a body, hybrid leg-wheels and driving mechanisms is provided. The hybrid leg-wheels are disposed around the body for carrying the body moving on a working surface. The driving mechanisms are disposed between the corresponding hybrid leg-wheels and the body. Each driving mechanism includes a driving axle connecting the corresponding hybrid leg-wheels and the body. Each driving mechanism provides the corresponding hybrid leg-wheel a rotational degree of freedom and a translational degree of freedom, wherein the rotational degree of freedom and the translational degree of freedom are driven independently. The rotational degree of freedom allows the hybrid leg-wheels rotating along an axis of the driving axle, and the translational degree of freedom allows the hybrid leg-wheels translating relative to the driving axle, wherein the rotational direction is substantially perpendicular to the translational direction.Type: GrantFiled: March 9, 2010Date of Patent: November 13, 2012Assignee: National Taiwan UniversityInventors: Pei-Chun Lin, Shuan-Yu Shen

Patent number: 8031029Abstract: A compensation method compensates for a length offset between a first transmission line and a second transmission line of a differential signal transmission. The compensation method includes calculating a transmission speed of a first signal in the first transmission line, measuring lengths of the first and second transmission lines, calculating a transmission time of the first signal in the first transmission line, and calculating a relationship between permittivity values of the first and second transmission lines. The compensation method further changes the permittivity values of the first and second transmission lines according to the relationship.Type: GrantFiled: April 27, 2009Date of Patent: October 4, 2011Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Yu-Chang Pai, Chien-Hung Liu, Po-Chuan Hsieh, Pei-Chun Lin, Shou-Kuo Hsu
