Publication number: 20240015828Abstract: The present invention provides a wireless communication method of a multi-link device. The wireless communication method includes the steps of: establishing multiple links with an access point, wherein the multiple links have a current link mode; determining performance of a current link mode and at least one candidate link mode, wherein frequency band(s) corresponding to the current link mode and the at least one candidate link mode are not the same; and if the performance of one of the at least one candidate link mode is greater than the performance of the current link mode, switching the link mode of the multiple links, without reconnecting to the access point, so that the one of the at least one candidate link mode serves as the current link mode to communicate with the access point.Type: ApplicationFiled: June 29, 2023Publication date: January 11, 2024Applicant: MEDIATEK INC.Inventors: Li-Tien Chang, Cheng-Yi Chang, Chun-Ting Lin

Patent number: 10001987Abstract: A method is for updating an original firmware file of an I/O module which communicates with multiple host-end devices and stores the original firmware file. The method includes: receiving a current-received data packet from one host-end device; when it is determined that the current-received data packet is a first data packet constituting an update file, and that the original firmware file is not undergoing an update process, setting a status flag to indicate that the original firmware file is undergoing an update process, storing the current-received data packet; and repeating the previous steps when it is determined that the current-received data packet is not a last one data packet constituting the update file.Type: GrantFiled: April 25, 2017Date of Patent: June 19, 2018Assignee: Mitac Computing Technology CorporationInventors: Yi-Lan Lin, Jen-Chih Lee, Kwang-Chao Chen, Hung-Tar Lin, Li-Tien Chang, Heng-Chia Hsu

Patent number: 8728874Abstract: Provided is an interleaved or wavy spatial arrangement of the micro-vias providing the electrical pathways for the power and ground leads are described. The spatial arrangement increases the coupling pairs between power and ground vias or leads. This spatial arrangement is maintained even as the micro-vias transition across a plane from a direction of travel. Thus, the charge from the decoupling capacitor is able to more efficiently be delivered as the inductances are minimized through this design.Type: GrantFiled: March 13, 2012Date of Patent: May 20, 2014Assignee: Altera CorporationInventor: Li-Tien Chang

Patent number: 8242608Abstract: A bump array structure for an integrated circuit is presented. An array of metal alloy bumps is disposed on a surface of the integrated circuit. The array of metal alloy bumps is configured to receive input from a multi-layer substrate package and transmit output to the multi-layer substrate package. The array defines a first portion of metal alloy bumps around the periphery of the surface of the integrated circuit configured to provide power and ground signals for the integrated circuit. The array further defines a second portion of metal alloy bumps providing power and ground for the integrated circuit, located between opposing sides of the periphery of the integrated circuit. Metal alloy bumps not contained in either the first or the second portion of the array are configured for input and output signals between the integrated circuit and the multi-level substrate package.Type: GrantFiled: September 30, 2008Date of Patent: August 14, 2012Assignee: Altera CorporationInventors: Li-Tien Chang, Yuanlin Xie
