Patent number: 10673104Abstract: A method is provided for testing a semi-finished battery cell. The semi-finished battery cell is charged with a constant current when a voltage difference between the first conductor and the second conductor is less than a voltage threshold. The semi-finished battery cell is charged with a constant voltage when the voltage difference between the first conductor and the second conductor is equal to or larger than the voltage threshold. An overall electric quantity is obtained after a default time period, wherein the overall electric quantity is an electric quantity charged to the semi-finished battery cell with the constant current during the default time period.

Publication number: 20180031637Abstract: A battery testing device includes a power supply, a voltmeter, a galvanometer, a differential circuit and an analyzer. The power supply is configured to provide a constant-current signal or a constant-voltage signal to a subject battery. The voltmeter is configured to detect a voltage waveform generated by the subject battery when the power supply provides the constant-current signal to the subject battery. When a voltage value of the voltage waveform achieves a threshold voltage value, the power supply switches to provide the constant-voltage signal to the subject battery. The galvanometer is configured to detect a current waveform generated by the subject battery. The differential circuit processes the voltage waveform and the current waveform by a second-order differential. The analyzer determines a testing result of the subject battery according to the processed voltage waveform and the processed current waveform.Type: ApplicationFiled: May 17, 2017Publication date: February 1, 2018Inventor: Chih-Ming TSAI

Patent number: 9562928Abstract: An active probe pod used in a logic analyzer is disclosed. The active probe pod may be connected to the logic analyzer having a FPGA decoder and to a DUT circuit board. The active probe pod may include a LVDS differential ire component connected to the FPGA decoder and a front-end circuit board for capturing a weak signal input from the DUT circuit board. The front-end circuit board is adapted not to transmit the captured weak signal input over a long-distance signal transmission path, which helps minimize interferences with the weak signal input, while outputting a LVDS differential signal to the FPGA decoder for decoding. As the front-end circuit board is used for capturing the weak signal input, which falls within the category of one short-distance signal transmission, the signal reflection may not take place, without affecting the signal quality and/or attenuating the signal strength.Type: GrantFiled: December 18, 2014Date of Patent: February 7, 2017Assignee: ZEROPLUS TECHNOLOGY CO., LTD.Inventors: Chiu-Hao Cheng, Chih-Ming Tsai

Publication number: 20130266108Abstract: The present invention discloses a water level determining method for a boiling water reactor. Thereby, for a boiling water reactor under anticipated transient without scram, risk of sudden power increase due to the uncertain water level raised to a main steam tube can be reduced by installing a thermometer on the top of the reactor or the main steam tube. By controlling flow rate of water and keeping the steam temperature higher than the saturated temperature, the core of the reactor can be sure to cool down properly.Type: ApplicationFiled: April 10, 2012Publication date: October 10, 2013Applicant: INSTITUTE OF NUCLEAR ENERGY RESEARCH, ATOMIC ENERGY COUNCIL, EXECUTIVE YUANInventors: Sheng-Yuan Fan, Shih-Jen Wang, Chih-Ming Tsai

Patent number: 7683663Abstract: A system implements and authorizes use of a user design. A non-volatile memory stores combined configuration data including first configuration data for implementing a user design and an authorization module, and second configuration data for implementing a generator of a check code. In response to a reset, a programmable integrated circuit loads the first configuration data to implement the user design and the authorization module. The implemented authorization module generates an activation code from an identifier when the check code is available from the non-volatile memory and enables the user design when the check and activation codes match. The programmable integrated circuit loads the second configuration data to implement the generator when the check code is not available from the non-volatile memory. The implemented generator erases the second configuration data from the non-volatile memory, generates the check code from the identifier, and stores the check code in the non-volatile memory.Type: GrantFiled: January 13, 2009Date of Patent: March 23, 2010Assignee: XILINX, Inc.Inventor: Chih-Ming Tsai
