Publication number: 20240162833Abstract: A power supply unit supplies power to a load, and the power supply unit includes a power factor corrector, a DC conversion module, and an isolated conversion module. The power factor corrector is plugged into a first main circuit board and converts an AC power into a DC power. The DC conversion module is plugged into the first main circuit board and converts the DC power into a main power. The isolated conversion module includes a bus capacitor, the bus capacitor is coupled to the DC conversion module through a first power copper bar, and coupled to the power factor corrector through a second power copper bar. The first power copper bar and the second power copper bar are arranged on a side opposite to the first main circuit board, and are arranged in parallel with the first main circuit board.Type: ApplicationFiled: November 13, 2023Publication date: May 16, 2024Inventors: Yi-Sheng CHANG, Cheng-Chan HSU, Chia-Wei CHU, Chun-Yu YANG, Deng-Cyun HUANG, Yi-Hsun CHIU, Chien-An LAI, Yu-Tai WANG, Chi-Shou HO, Zhi-Yuan WU, Ko-Wen LU

Publication number: 20240130038Abstract: A transmission device for suppressing the glass-fiber effect includes a circuit board and a transmission line. The circuit board includes a plurality of glass fibers, so as to define a fiber pitch. The transmission line is disposed on the circuit board. The transmission line includes a plurality of non-parallel segments. Each of the non-parallel segments of the transmission line has an offset distance with respect to a reference line. The offset distance is longer than or equal to a half of the fiber pitch.Type: ApplicationFiled: November 23, 2022Publication date: April 18, 2024Applicants: UNIMICRON TECHNOLOGY CORP., National Taiwan UniversityInventors: Chin-Hsun WANG, Ruey-Beei Wu, Ching-Sheng Chen, Chun-Jui Hung, Wei-Yu Liao, Chi-Min Chang

Patent number: 11918387Abstract: An infant care apparatus includes a piezoelectric sensor and an infrared array sensor. The piezoelectric sensor senses a respiration rate and a heart rate of an infant. The infrared array sensor senses a body temperature and an occupancy state of the infant in a non-contact manner. The abovementioned infant care apparatus can assist in determining an abnormality of the respiration rate and the heart rate of the infant based on the occupancy state of the infant output by the infrared array sensor, so as to reduce a false alarm rate.Type: GrantFiled: December 4, 2020Date of Patent: March 5, 2024Assignee: ORIENTAL SYSTEM TECHNOLOGY INC.Inventors: Chein-Hsun Wang, Chun-Chiang Chen, Wen-Chie Huang, Ming Le

Patent number: 8328363Abstract: An optical system includes a light source array, a dichroic mirror set, a light converting device and a light guide pipe. The light source array is used for emitting a first homogeneous light. The dichroic mirror set is disposed in a light path of the first homogeneous light and used for reflecting a part of the first homogeneous light to the light guide pipe, transmitting the remaining part of the first homogeneous light to the converting device. The light converting device is disposed in the transmitting light path of the dichroic mirror and used for transferring the first homogeneous light into a second, third homogeneous light. The dichroic mirror is further used for reflecting the second, third homogeneous light to the light guide pipe. The light guide pipe is used for mixing the first, second and third homogeneous light to obtain a white light.Type: GrantFiled: March 28, 2010Date of Patent: December 11, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Ming-Te Lin, Wen-Pin Yeh, Chun-Hsun Wang
