Patent number: 10366625Abstract: A kinesthetic device that simulates flight includes a base unit and a swing unit. The base unit includes a base seat; whereas, the swing unit includes a swing seat, two swing support structures pivoted between the base seat and the swing seat, and a swing actuator used to control the swing positions of the two swing support structures. The two swing support structures are equal in length and parallel to each other. A fixed baseline is formed between two junction points between the two swing support structures and the base seat, a swing baseline is formed between two junction points between the two swing support structures and the swing seat, and the fixed baseline and the swing baseline are equal in length. The two swing support structures, the fixed baseline and the swing baseline form a parallelogram, allowing the swing support structures to swing stably the base seat.Type: GrantFiled: January 17, 2018Date of Patent: July 30, 2019Assignee: Brogent Technologies Inc.Inventors: Wei-Ching Tang, Ke-Cheng Chien, Tien-Ni Cheng

Publication number: 20180125172Abstract: A latch device comprises a housing unit, a disk unit, an electromagnetic lock unit, a pressing lock unit, and a detecting unit. The housing unit includes a housing, which has a pressing hole and an insertion slot. The disk unit includes a supporting rod positioned through the housing, and two vertical disks pivotally arranged to the supporting rod. The outer perimeter of the two disks is placed with a hook, a first engaging portion and a second engaging portion. The electromagnetic lock unit includes two electromagnetic mechanisms, two retractable bars connected to the two electromagnetic mechanisms, and two electromagnetic latches respectively connected to the two retractable bars. The pressing lock unit includes a pushbutton, and a button latch connected to the pushbutton. The detecting unit includes two detectors, which are disposed inside the housing for detecting the position of the two electromagnetic latches.Type: ApplicationFiled: October 19, 2017Publication date: May 10, 2018Inventors: Ke-Cheng Chien, Wei-Ching Tang, Chih-Chiang Huang, Guo-Sen Lian, Shih-Kuang Chiu

Patent number: 7967688Abstract: A motion simulator has a motive device suspended in midair and having a base, a moving panel, twelve universal joints mounted on the base and the moving panel and six actuators connected to the universal joints and being retractable. A seat assembly is hung on the moving panel. Therefore, as the actuators retract, the seat assembly is moved in six degrees of freedom such as heave, sway, surge, pitch, roll and yaw. Audiences sitting on the seat assembly are hung with their feet hanging in the air and therefore feel excited and experience vivid virtual reality. Moreover, the actuators bear axial force such as drag force and thrust force and are endurable and safety.Type: GrantFiled: January 16, 2009Date of Patent: June 28, 2011Assignees: Brogent Technologies, Inc.Inventors: Deng-Horng Lai, Ke-Cheng Chien
