Patent number: 10152911Abstract: A power supply circuit includes a comparison circuit, a preset value setting circuit, a reset detecting circuit and a reset signal generating circuit. The comparison circuit compares a first and second voltage to output a comparing result. The first and second voltages correspond to a first and second preset value, respectively. When the comparison result shows that the second voltage is greater than the first voltage, the preset value setting circuit outputs the second preset value; otherwise it outputs a third preset value, which is greater than the first preset value. The reset detecting circuit determines whether the operation voltage of the power supply circuit drops to the preset value outputted by the preset value setting circuit, and outputs a control signal accordingly. The reset signal generating circuit determines whether to output a reset signal for resetting gate lines in a display panel based on the control signal.Type: GrantFiled: November 15, 2016Date of Patent: December 11, 2018Assignee: AU OPTRONICS CORPORATIONInventors: Wei-Chin Tsai, Chun-Kuei Wen

Patent number: 7685339Abstract: A remote control system and a method thereof are provided. The remote control system includes a first host, an adapter, and a peripheral device. The first host converts a first serial signal into a first network packet, and then outputs the first network packet through a network. The adapter is connected to the network to receive the first network packet, and then converts the first network packet into a second serial signal complying with a universal serial bus (USB) format. The peripheral device is coupled to the adapter through the USB, and receives the second serial signal, so that the user can control the peripheral device at a remote site through the network.Type: GrantFiled: August 29, 2007Date of Patent: March 23, 2010Assignee: Arcadyan Technology CorporationInventors: Wei-Chin Tsai, Yun-Fuh Yeh, Hais-Heng Liu, Jun Zheng, Wen-Fang Yan

Publication number: 20080307083Abstract: A method of managing a gateway by a specific domain name is provided. The method includes firstly setting a DNS to connect to the internet. Next, a specific domain name for the gateway is defined. Then, the specific domain name is stored in the DNS for connecting the gateway according to the specific domain name. The present method maps the specific domain name to an IP address of the gateway, such that a user can manage the gateway by using the specific domain name instead of memorizing the IP address of the gateway, which is more convenient.Type: ApplicationFiled: November 9, 2007Publication date: December 11, 2008Applicant: ARCADYAN TECHNOLOGY CORPORATIONInventors: Wei-Chin Tsai, Yun-Fuh Yeh
