Patent number: 12352365Abstract: An integrated air valve includes a hollow shell formed with a valve installation space, two air holes respectively an air inlet hole and an exhaust hole communicated to the space, and two support members; two lever members; and two shape memory alloy members. The lever member uses one of the support members as a fulcrum. The lever member includes an actuating end, and an action end capable of closing the air hole. A part of the shape memory alloy members are hung on the actuating ends of the lever members, and capable of driving the lever members based on an energized state. One of the lever members determines conduction of the air inlet hole to achieve air intake, the other lever member determines whether the exhaust hole communicates to an external space to achieve exhaust, and the lever members determine whether the integrated air valve enters air pressure maintenance.Type: GrantFiled: December 28, 2023Date of Patent: July 8, 2025Assignee: TangTring Seating Technology Inc.Inventors: Tsun-Hsiang Wen, Shih-Chung Hsu, Chia-Yu Yu, Peng Zhao

Patent number: 11982369Abstract: An air valve structure arranged on a base comprises an air plug and a state-switching component. The air plug is arranged in an air chamber in an axial direction. The air plug includes a closing state to close the air hole, and an opening state to open the air hole. The state-switching component comprises a driving member that links the air plug, a shape-memory alloy (SMA) wire connected with the driving member, and at least one conductive member connected with the SMA wire. The driving member exerts an acting force to the air plug based on a condition of electricity provided by the conductive member for the SMA wire. The direction of the acting force is non-parallel with the axial direction and the air plug is moved and changed between the closing state and the opening state by the acting force.Type: GrantFiled: June 1, 2022Date of Patent: May 14, 2024Assignee: TANGTRING SEATING TECHNOLOGY INCInventors: Tsun-Hsiang Wen, Shih-Chung Hsu, Jun Xie, Jian Zeng, Xian-Chang Zou

Patent number: 11781669Abstract: An air valve comprises a casing, a valve body driving assembly and a valve body. The casing comprises a chamber, a vent hole, and at least one switching hole communicating with the chamber. The valve body driving assembly is disposed in the chamber, and comprises a pusher, a shape memory metal wire in a linkage relationship with the pusher, and two conductive members disposed in the casing and located at two ends of the shape memory metal wire respectively, the pusher travels a uniaxial displacement stroke due to a temporary change of the shape memory metal wire. The valve body is disposed in the chamber and faces the switching hole, when the pusher travels the uniaxial displacement stroke, the valve body is driven to rotate a central angle relative to the switching hole to change a ventilation state between the switching hole and the chamber.Type: GrantFiled: May 12, 2022Date of Patent: October 10, 2023Assignee: TANGTRING SEATING TECHNOLOGY INC.Inventors: Tsun-Hsiang Wen, Shih-Chung Hsu, Jun Xie, Jian Zeng, Xian-Chang Zou

Publication number: 20220379433Abstract: Provided is a dressing device for a carrier. The dressing device comprises a dresser, a swing arm, a base and at least one damper. A first end and a second end of the swing arm are coupled to the dresser and the base, respectively, and the at least one damper is disposed inside the swing arm. Any axial vibration of the dresser or the swing arm during dressing for the carrier can be compensated or attenuated by the damper in an active manner properly, so as to make the surface of the carrier flatter and more uniform, which not only improves a removal rate of material and a polishing result of the surface in the subsequent chemical mechanical planarization process, but also prolongs the service life of the carrier. The present disclosure further relates to a polishing system for dressing the carrier by using the said dressing device.Type: ApplicationFiled: May 26, 2022Publication date: December 1, 2022Inventors: Chao-Chang Chen, Jen-Chieh Li, Cheng-Hsi Chuang, Shih-Chung Hsu, Yu-Tung Tsai, Hsien-Ming Lee, Chun-Chen Chen, Ching-Tang Hsueh

Patent number: 5864294Abstract: The present invention provides a docking station, a docking station system, and a method of coupling a personal computer, typically a palm top, notepad, or ideally a notebook computer, with such a computer docking station. The computer is typically manually positioned and securely held in place within a computer receptacle of the docking station. Generally, the computer will include an LED (or other signal generator) which indicates the operating mode of the computer, typically indicating at least one of off, on, or suspense mode. The docking station thereby senses whether it is appropriate to engage a docking station connector to a computer connector based on the computer operating mode. Typically, the connection will be made if the computer is either off or in the suspense mode. When connection is appropriate, the docking station connector is automatically translated to engage the computer connector of the fixed notebook computer.Type: GrantFiled: April 1, 1996Date of Patent: January 26, 1999Assignee: Acer, Inc.Inventors: Shih-Chung Hsu, Wei-Chia Chao, Chien-An Chen
