Publication number: 20240110576Abstract: An impeller is provided, including a metal housing, a shaft, and a plastic member. The metal housing has a shaft mounting hole. The inner surface of the shaft mounting hole includes three or more contact points, and the contact points are closer to the shaft than other portions of the inner surface of the shaft mounting hole. The shaft passes through the shaft mounting hole and is affixed by the contact points. The metal housing divides the shaft into an upper section, a middle section, and a lower section. The plastic member passes through the shaft mounting hole and is in contact with the middle section.Type: ApplicationFiled: December 13, 2023Publication date: April 4, 2024Inventors: Wei-I LING, Chao-Fu YANG, Chih-Chung CHEN, Kuo-Tung HSU

Patent number: 11916075Abstract: An integrated circuit (IC) structure includes a substrate having several regions, several semiconductor devices formed at the substrate and respectively within the regions, and an ultra-deep (UD) trench isolation structure formed in the substrate. The substrate has a top surface and a bottom surface oppositely, and the UD trench isolation structure formed in the substrate surrounds peripheries of each of the regions for structurally and physically isolating the semiconductor devices within different regions. The UD trench isolation structure penetrates the substrate by extending from the top surface of the substrate to the bottom surface of the substrate.Type: GrantFiled: May 10, 2022Date of Patent: February 27, 2024Assignee: UNITED MICROELECTRONICS CORP.Inventors: Wei-Lun Hsu, Yung-Chien Kung, Ming-Tsung Yeh, Yan-Hsiu Liu, Am-Tay Luy, Yao-Pi Hsu, Ji-Fu Kung

Patent number: 11171488Abstract: A solar power system may include a solar panel set, a lithium battery set, a first controller, and a second controller. A single-contact switch is electrically connected between the solar panel set and the lithium battery set. When the first controller detects that the generated voltage of the solar panel set reaches a preset threshold value, the first controller is adapted to trigger the first awakening of the lithium battery set by electrically conducting the single-contact switch, thereby brought the lithium battery set out of the low potential protection state. Also, when the second controller detects the voltage of the lithium battery set is not rising after the first awakening of the lithium battery set, the first controller is driven by the second controller to process the second awakening of the lithium battery set through the single-contact switch.Type: GrantFiled: August 27, 2020Date of Patent: November 9, 2021Assignee: AVERTRONICS INC.Inventors: Austin Lai, Kai-Yang Cheng, Wei-Fu Hsu, Chun-Yu Wu

Publication number: 20210119481Abstract: An intelligent off-peak power distribution system may include a plurality of power consumption ends powered by a plurality of batteries. Each of the batteries is individually programmed with an electronic code, and the batteries are charged by at least a power supply end, and the charging method thereof is to use off-peak power to perform charging during off-peak hour. At least a distribution vehicle is provided to transport the batteries between the power consumption ends and the power supply end, and a smart communication network is communicated with the power consumption ends, the distribution vehicle, and the power supply end. The batteries are available and transported between the power consumption ends by the distribution vehicle so that the distribution vehicle departing from the power supply end is configured to distribute power to more power consumption ends in a single ride, thereby reducing the power and transportation costs.Type: ApplicationFiled: October 22, 2019Publication date: April 22, 2021Applicant: AVERTRONICS INC.Inventors: Austin Lai, Kuan-Ching Lee, Hong-Min Chen, Kai-Yang Cheng, Wei-Fu Hsu, Hui-Ping Yang, Ya-Ling Lien

Patent number: 10826320Abstract: A solar power system may comprise a solar panel set, a controller, a lithium battery set, and at least a DC load. The controller has a control unit built therein to control a double-contact relay, a single-contact relay, and a transformer. The rated voltage of the solar panel set is higher than the rated voltage of the lithium battery set between 115% and 130%. When the actual voltage of the solar panel set is lower than 115% of the rated voltage of the lithium battery set, the solar panel set is configured to low-loss charge the lithium battery set under the low illumination condition. When the actual voltage of the solar panel set is higher than 115% of the rated voltage of the lithium battery set, the solar panel set under the high illumination condition is adapted to have voltage-drop through the transformer and high-efficiently charge the lithium battery set.Type: GrantFiled: February 11, 2019Date of Patent: November 3, 2020Inventors: Austin Lai, Kai-Yang Cheng, Wei-Fu Hsu, Kuan-Ching Lee, Hui-Ping Yang

Patent number: 10666186Abstract: A movable solar power apparatus may comprise at least a solar panel set electrically connected to a maximum power point tracking system (MPPT). A lithium battery set is electrically connected to a battery management system (BMS) which is adapted to monitor and protect the lithium battery set, and the BMS is electrically connected to the MPPT to enable power generated by the solar panel set to directly charge the lithium battery set. A low potential wake-up circuit has a double-contact relay and a single-contact relay, and the double-contact relay comprises a main contact, a first contact, and a second contact. The main contact is switchably electrically connected to the first contact or the second contact, and the main contact is electrically connected to the BMS while the first contact is electrically connected to the master control circuit, and the MPPT is electrically connected to the BMS under normal condition.Type: GrantFiled: June 25, 2018Date of Patent: May 26, 2020Assignee: AVERTRONICS INC.Inventors: Austin Lai, Kai-Yang Cheng, Wei-Fu Hsu
