Patent number: 11890256Abstract: An active rollator includes an auxiliary frame, a driving assembly, a sensing assembly, and a controller. The sensing assembly is configured to sense an operation area and output a sensing signal. When a user holds handlebars of the auxiliary frame and stands in the operation area, the controller is configured to, according to the sensing signal and a sensing threshold, control the driving assembly to make the auxiliary frame have a motion. Therefore, the active rollator aids the travel of the user.Type: GrantFiled: November 19, 2020Date of Patent: February 6, 2024Assignee: WISTRON CORPORATIONInventors: Ming-Ru Syue, Cheng-Hsing Liu, Jia-Hung Lee

Patent number: 9069529Abstract: A lifting mechanism includes a lifting member, a first magnetic member, a rotating arm, a second magnetic member and a resilient member. The lifting member is pivoted to a first casing. The first magnetic member is fixed on the lifting member. The rotating arm is pivoted to a second casing. The second magnetic member is fixed on the rotating arm for attracting the first magnetic member as being rotated with the rotating arm to where the second magnetic member is aligned with the first magnetic member, so as to retract the lifting member inside the first casing. The resilient member resiliently abuts against the second casing and the lifting member for pushing the lifting member as being rotated with the rotating arm to where the second magnetic member is not aligned with the first magnetic member, so as to expand the lifting member out of the first casing.Type: GrantFiled: July 3, 2013Date of Patent: June 30, 2015Assignee: Wistron CorporationInventors: Jia-Hung Lee, San-Pao Kao, Cheng-Hsiang Chuang

Patent number: 8699224Abstract: The present disclosure relates to a computer peripheral device. The computer peripheral device includes a housing whereon an opening is formed, and a fixing module installed inside the opening in a reversible manner. The fixing module includes a base installed inside the opening, a locking head passing through the locking plate and fixed on the base at one end. The locking head includes a latching part for inserting into a slot on a casing of a portable computer when the base turns to a first position relative to the housing so that the latching part protrudes outside the housing. When the locking plate is pressed down so as to separate the latching part from the locking plate and the locking head rotates relative to the locking plate, the latching part cannot separate from the slot. The fixing module further includes a resilient component for pushing the locking plate.Type: GrantFiled: April 26, 2012Date of Patent: April 15, 2014Assignee: Wistron CorporationInventors: Yen-Chang Lai, Jia-Hung Lee

Patent number: 8531837Abstract: A pad mechanism includes a step fixing structure having a plurality of step platforms. A height difference is formed between the two step platforms. A first engaging portion is formed on each step platform. The pad mechanism further includes a pad component having a pad body, a sleeve and a constraining portion. A second engaging portion is formed on the pad body for selectively engaging with the corresponding first engaging portion so as to adjust a height of the pad body protruding from the step fixing structure. The pad mechanism further includes a resilient component sheathing with the sleeve for driving the sleeve, and a constraining component installed on a side of the resilient component and connected to the constraining portion so as to prevent the resilient component from separating from the sleeve.Type: GrantFiled: December 19, 2011Date of Patent: September 10, 2013Assignee: Wistron CorporationInventors: Jia-Hung Lee, Chien-Heng Kuo, Yen-Chang Lai

Patent number: 8499183Abstract: A plug assembly includes a first plug and a second plug. The first plug includes a main body whereon a first positive electrode, a first negative electrode and a first engaging portion are formed. The second plug has a chamber structure formed inside for containing the main body. A second positive electrode, a second negative electrode and a second engaging portion are formed on the chamber structure and located in positions corresponding to the first positive electrode, the first negative electrode and the first engaging structure, respectively. As the chamber structure completely contains the main body, the second positive electrode and the second negative electrode are respectively coupled to the first positive electrode and the first negative electrode, and the second engaging portion engages the first engaging portion, such that the main body is hold inside the chamber structure.Type: GrantFiled: November 15, 2011Date of Patent: July 30, 2013Assignee: Wistron CorporationInventors: Yen-Chang Lai, Chien-Heng Kuo, Jia-Hung Lee
