Publication number: 20170229954Abstract: A power supply apparatus includes a switch, a converting module and a control module. When the switch operates in an ON state, an input voltage is outputted through the switch to serve as an output voltage.

Patent number: 9030794Abstract: An electronic fuse apparatus is connected between a power side and a system side. The electronic fuse apparatus mainly includes an electronic fuse, a short-circuit protection switch, a current-sensing module, and a digital control module. The current-sensing module detects an operating current which flows from the power side to the system side. The digital control module generates a control signal to control the electronic fuse. When the current-sensing module detects that the operating current is over-current, the digital control module generates the high-level control signal to turn off the electronic fuse, thus providing an over-current protection. When a short-circuit fault occurs at the system side, the short-circuit protection switch is turned on to turn off the electronic fuse, thus providing a short-circuit protection.Type: GrantFiled: October 9, 2013Date of Patent: May 12, 2015Assignee: Delta Electronics, Inc.Inventors: Ching-Long Tsai, Yi-Hsin Leu, Ming-Tsung Hsieh, Der-Min Liu

Publication number: 20100177606Abstract: A method for identifying a layer number of an optical disc is provided. Firstly, a SA value is adjusted to a standard SA value of each of two data layers in sequence. Next, focusing courses are performed so as to enable the focus point to pass through the optical disc. Then, maximum amplitudes of focusing error signals in the focusing courses are recorded. After that, whether the maximum amplitudes of the focusing error signals recorded in the focusing courses are equal is checked. If the maximum amplitudes are equal, the optical disc is identified as a double-layered disc. If the maximum amplitudes are not equal, the optical disc is identified as a single-layered disc.Type: ApplicationFiled: January 6, 2010Publication date: July 15, 2010Applicant: QUANTA STORAGE INC.Inventors: Chia-Hsing HSU, Ming-Tsung Hsieh, Yi-Long Hsiao
