Publication number: 20120133374Abstract: A method for detecting a capacitor loss is applicable to detecting a plurality of by-pass capacitors connected in parallel to each other. The detection method includes the following steps, an alternating current (AC) signal is input into the by-pass capacitors, in which the AC signal has a plurality of test frequencies; test voltages of the by-pass capacitors at each of the test frequencies are recorded, so as to form a test result table; it is determined whether the test result table is the same as a standard voltage table; and when a result of the determination is NO, a fail signal is output. By applying the detection method, whether a loss exists in the by-pass capacitors can be effectively identified, thereby solving the problem that small capacitors are undetectable when large capacitors are connected in parallel to the small capacitors.Type: ApplicationFiled: March 23, 2011Publication date: May 31, 2012Applicant: INVENTEC CORPORATIONInventors: Chih-Jen Chin, Quan-Jie Zheng, Ping Song, Chih-Feng Chen

Publication number: 20120137027Abstract: A system and method for monitoring an input/output port status of peripheral devices are used for monitoring an operating status of each peripheral device of a main board. The system includes at least one peripheral device, a complex programmable logic device (CPLD), and an output apparatus. The CPLD is electrically connected to the peripheral devices. The CPLD further includes a protocol conversion unit and multiple data registers. The protocol conversion unit converts an operating status of the CPLD or the peripheral devices into device status information. The data register is used for storing the device status information. The output apparatus is electrically connected to the CPLD. The output apparatus is used for displaying the device status information in the data register. A user can observe the operating status of each of the peripheral devices of the main board conveniently.Type: ApplicationFiled: March 24, 2011Publication date: May 31, 2012Applicant: INVENTEC CORPORATIONInventors: Quan-Jie Zheng, Chih-Jen Chin, Ya-Jing Fan, Chih-Feng Chen

Publication number: 20090089003Abstract: An accessory-testing device for an information processing apparatus includes a micro-processing unit (MPU) and a signal conversion unit. The MPU sends a mimic signal. The signal conversion unit is electrically connected to the MPU and an accessory respectively, for receiving the mimic signal and converting the mimic signal into a test signal to test the accessory. The accessory receives the test signal and then responds to the test signal to output a feedback signal. The feedback signal is received by the signal conversion unit and transmitted to the MPU, such that the MPU determines if the accessory operates normally according to the feedback signal. Conventional testing methods are Therefore, it is achieved that the effects of reducing the inspection time and improving the production efficiency.Type: ApplicationFiled: September 28, 2007Publication date: April 2, 2009Inventors: Xue-Shan Han, Quan-Jie Zheng, Jeff Song, Jhih-Ren Jin, Tom Chen, Win-Harn Liu
