Publication number: 20240127988Abstract: An over-current protection device includes a first metal layer, a second metal layer and a heat-sensitive layer laminated therebetween. The heat-sensitive layer exhibits a positive temperature coefficient (PTC) characteristic and includes a first polymer and a conductive filler. The first polymer consists of polyvinylidene difluoride (PVDF), and PVDF exists in different phases such as ?-PVDF, ?-PVDF and ?-PVDF. The total amount of ?-PVDF, ?-PVDF and ?-PVDF is calculated as 100%, and the amount of ?-PVDF accounts for 48% to 55%. The conductive filler has a metal-ceramic compound.Type: ApplicationFiled: March 2, 2023Publication date: April 18, 2024Inventors: HSIU-CHE YEN, YUNG-HSIEN CHANG, CHENG-YU TUNG, Chia-Yuan Lee, CHEN-NAN LIU, Yao-Te Chang, FU-HUA CHU

Patent number: 11955154Abstract: A sense amplifier circuit includes a sense amplifier, a switch and a temperature compensation circuit. The temperature compensation circuit provides a control signal having a positive temperature coefficient, based on which the switch provides reference impedance for temperature compensation. The sense amplifier includes a first input end coupled to a target bit and a second input end coupled to the switch. The sense amplifier outputs a sense amplifier signal based on the reference impedance and the impedance of the target bit.Type: GrantFiled: May 16, 2022Date of Patent: April 9, 2024Assignee: UNITED MICROELECTRONICS CORP.Inventors: Cheng-Tung Huang, Jen-Yu Wang, Po-Chun Yang, Yi-Ting Wu, Yung-Ching Hsieh, Jian-Jhong Chen, Chia-Wei Lee

Patent number: 11946569Abstract: An actuating and sensing module is disclosed and includes a bottom plate, a gas pressure sensor, a thin gas transportation device and a cover plate. The bottom plate includes a pressure relief orifice, a discharging orifice and a communication orifice. The gas pressure sensor is disposed on the bottom plate and seals the communication orifice. The thin gas transportation device is disposed on the bottom plate and seals the pressure relief orifice and the discharging orifice. The cover plate is disposed on the bottom plate and covers the gas pressure sensor and the thin gas-transportation device. The cover plate includes an intake orifice. The thin gas transportation device is driven to inhale gas through the intake orifice, the gas is then discharged through the discharging orifice by the thin gas transportation device, and a pressure change of the gas is sensed by the gas pressure sensor.Type: GrantFiled: April 19, 2021Date of Patent: April 2, 2024Assignee: MICROJET TECHNOLOGY CO., LTD.Inventors: Hao-Jan Mou, Shih-Chang Chen, Jia-Yu Liao, Hung-Hsin Liao, Chung-Wei Kao, Chi-Feng Huang, Yung-Lung Han, Chang-Yen Tsai, Wei-Ming Lee

Publication number: 20240080505Abstract: A method, comprising: detecting an outage of at least one functionality in a live streaming; performing an first operation toward a second user terminal; storing data of the first operation in a database of the first user terminal; and displaying an effect corresponding to the first operation during the outage. The present disclosure may store the data of operation performed by the user terminal during outage and process the operation after the outage is recovered. Therefore, the streamers and viewers may feel interested and satisfied, instead of feeling anxious, and the user experience may be enhanced.Type: ApplicationFiled: June 23, 2023Publication date: March 7, 2024Inventors: Yung-Chi HSU, Hsing-Yu TSAI, Chia-Han CHANG, Yi-Jou LEE, Ming-Che CHENG

Patent number: 8196758Abstract: A frame assembly includes upper and lower frame units, four vertical frame rods, four pairs of top and bottom female connectors, eight male connectors, and first and second bolts. Each frame unit includes four rectangularly-arranged horizontal frame rods. Each female connector interconnects an adjacent pair of the horizontal frame rods, and includes two horizontal tenons engaging respectively the adjacent pair of the horizontal frame rods. The male connectors are connected respectively to opposite ends of the vertical frame rods. Each male connector includes a vertical tenon engaging a respective one of the opposite ends of the vertical frame rods, and an engaging block mating with a respective one of the female connectors. The first and second bolts are for securing releasably and respectively the female connectors to the male connectors.Type: GrantFiled: January 6, 2011Date of Patent: June 12, 2012Inventor: Yung-Yu Lee

Patent number: 7724163Abstract: An apparatus and method of multi-stage network for iterative network are disclosed. The apparatus has M stages, and each stage uses N multiplexers to transmit N codeword partitions simultaneously. Every starting terminal, either the output port of memories, soft-in soft-out decoders, or multiplexers, has two paths to couple with two different multiplexers at next stage. One path connects the source to the first data port of one multiplexer; the other connects the source to the second data port of another multiplexer. The two multiplexers will be controlled with the same 1-bit signal, so each source has only one valid path to next stage. The invention can guarantee that the transmission of N data blocks is free from contention.Type: GrantFiled: July 24, 2008Date of Patent: May 25, 2010Assignee: National Chiao Tung UniversityInventors: Cheng-Chi Wong, Yung-Yu Lee, Ming-Wei Lai, Chien-Ching Lin, Hsie-Chia Chang, Chen-Yi Lee
