Publication number: 20240401714Abstract: A piezoelectric valve may be formed using semiconductor processing techniques such that the piezoelectric valve is biased in a normally closed configuration. Actuation of the piezoelectric valve may be achieved through the use of a piezoelectric-based actuation layer of the piezoelectric valve. The piezoelectric valve may be implemented in various use cases, such as a dispensing valve for precise drug delivery, a relief valve to reduce the occlusion effect in speaker-based devices (e.g., in-ear headphones), a pressure control valve, and/or another type of valve that is configured for microfluidic control, among other examples. The normally closed configuration of the piezoelectric valve enables the piezoelectric valve to operate as a normally closed valve with reduced power consumption.Type: ApplicationFiled: August 22, 2023Publication date: December 5, 2024Inventors: Yi-Hsien CHANG, Fu-Chun HUANG, Po-Chen YEH, Chao-Hung CHU, Ching-Hui LIN, Chun-Ren CHENG, Shih-Fen HUANG

Publication number: 20240354487Abstract: The present disclosure describes an example method for routing a standard cell with multiple pins. The method can include modifying a dimension of a pin of the standard cell, where the pin is spaced at an increased distance from a boundary of the standard cell than an original position of the pin. The method also includes routing an interconnect from the pin to a via placed on a pin track located between the pin and the boundary and inserting a keep out area between the interconnect and a pin from an adjacent standard cell. The method further includes verifying that the keep out area separates the interconnect from the pin from the adjacent standard cell by at least a predetermined distance.Type: ApplicationFiled: July 2, 2024Publication date: October 24, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Fong-yuan CHANG, Chun-Chen CHEN, Sheng-Hsiung CHEN, Ting-Wei CHIANG, Chung-Te LIN, Jung-Chan YANG, Lee-Chung LU, Po-Hsiang HUANG

Patent number: 7564747Abstract: A method for determining a compensation value for tracking error signal in an optical disc drive is disclosed. The optical disc drive rotates a DVD to read data. The DVD has a first reflection layer and a second reflection layer. The first and the second reflection layers have respectively a number of circles of first and second tracks. First, read data on two first and two second tracks and accordingly generate two first compensation values for tracking error signal and two second compensation values for tracking error signal. Next, determine the third compensation value for tracking error signal corresponding to each of the other first tracks according to two of the first compensation values for tracking error signal. Then, determine the forth compensation value for tracking error signal corresponding to each of the other second tracks according to two of the second compensation values for tracking error signal.Type: GrantFiled: June 16, 2005Date of Patent: July 21, 2009Assignee: Lite-On It CorporationInventors: Shih-Chang Cheu, Chih-Ming Lai, Po-Chen Huang, Chih-Chung Chiao

Patent number: 7505379Abstract: An intelligent layer jump method applied when an optical disc drive accesses a disc. The disc has a central reference point, at least a first recoding layer and a second recoding layer. The first recoding layer has a plurality of first tracks, while the second recoding layer has a plurality of second tracks. Firstly, a laser beam of the optical disc drive is focused on the first recoding layer to form a focal point and obtain an original position. Then, the relative position between an original position and a target position positioned on the second recoding layer are compared to determine a layer jump and track seeking path of the focal point. Lastly, the focal point is shifted from the original position to the target position according to the predetermined layer jump and track seeking path.Type: GrantFiled: June 15, 2005Date of Patent: March 17, 2009Assignee: Lite-On It CorporationInventors: Shih-Chang Cheu, Chih-Ming Lai, Po-Chen Huang, Chih-Chung Chiao

Publication number: 20070286034Abstract: A method of controlling an optical pick-up head to access an eccentric disk. When a loaded disk is determined as an eccentric disk causing a lens of the optical pick-up head crossing between a first track being close to the inner disk and a second track being close to outer disk, a tracking on position has to be concerned. IF a target track is close to the second track, provide a first force to move the lens a distance toward the inner disk then execute a track on operation. IF the target track is close to the first track, provide a second force to move the lens a distance toward the outer disk then execute a track on operation.Type: ApplicationFiled: March 21, 2007Publication date: December 13, 2007Applicant: LITE-ON IT CORP.Inventors: Po-Chen Huang, Chia-Hao Hsu, Yuyu Chen
