Patent number: 10818574Abstract: A plug-in type power module includes a power unit and a heat-transfer unit vertically disposed on the power unit and extending outwardly away from two sides of the power unit. A first ceramic layer is disposed between the power unit and the heat-transfer unit. Therefore, heat generated by the power unit can be transferred from the first ceramic layer to the heat-transfer unit to increase the speed of heat dissipation. A subsystem having the plug-in type power module is also provided.Type: GrantFiled: May 26, 2020Date of Patent: October 27, 2020Assignee: Industrial Technology Research InstituteInventors: Shu-Jung Yang, Yu-Lin Chao, Chun-Kai Liu, Ming Kaan Liang, Jiin Shing Perng

Patent number: 10288696Abstract: An intelligent diagnosis system for a power module. The system includes a power module, a hardware checking module and a diagnostic module. The power module has a temperature sensing element for obtaining a temperature difference between a starting minimum temperature and a current temperature. The hardware checking module has a current sensing element, a voltage sensing element and a magnetic coupling closed loop detection element for obtaining the current, the output voltage and the input voltage of the power module, and the hardware loop status, respectively. The diagnostic module calculates the number of cycles that have been operated, a measured impedance and an instantaneous power based on those measurement results, and calculating a risk index based on the number of cycles that have been operated, the temperature difference, the measured impedance, the instantaneous power and the hardware loop status, thereby determining the accumulation of the abnormality index record.Type: GrantFiled: November 16, 2016Date of Patent: May 14, 2019Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chih-Chung Chiu, Chih-Ming Tzeng, Li-Ling Liao, Yu-Lin Chao, Chih-Ming Shen, Ming-Kaan Liang, Chun-Kai Liu, Ming-Ji Dai

Patent number: 7998083Abstract: A method and device for automatically detecting heart valve damage for four heart valves are proposed. The automatic determination method makes use of three or more heart tone microphones to simultaneously record heart tones of a patient's heart, and then separates the heart tones into four heart tone signals of the aortic valve, the pulmonary valve, the tricuspid valve and the mitral valve of the heart based on the timing characteristics and related techniques. Next, these four heart tone signals are digitally processed into sampling signals. Subsequently, the convolution method is used to process the sampling signals for producing system transfer functions. Finally, the system transfer functions and the reference database are compared to verify and determine damage for the four heart valves. The automatic determination method can judge heart valve damage to enhance the quality and convenience of medical treatment.Type: GrantFiled: December 19, 2008Date of Patent: August 16, 2011Assignee: Industrial Technology Research InstituteInventors: Tsung-Ter Kuo, Mao-Shun Su, Yu-Kon Chou, Ming-Kaan Liang
