Patent number: 10705571Abstract: A foldable electronic device includes a first base, a second base, a hinge, a brake, an object sensor, and a controller. The hinge pivotally connects the first base to the second base. The brake is disposed in the hinge. When the first base is expanded with respect to the second base, the object sensor senses whether an object is placed on the second base. When the object sensor senses that the object is placed on the second base, the object sensor sends out a sensed signal. The controller selectively switches on the brake in response to the sensed signal, so as to restrain a rotating angle formed by the first base and the second base.Type: GrantFiled: June 13, 2019Date of Patent: July 7, 2020Assignee: Wistron CorporationInventors: Yuan-Tai Chen, Chia-Hao Liang, Cheng-Kuo Lee, Ming-Jen Chan

Patent number: 10305465Abstract: A transformer device and a control method for the transformer device are provided. The transformer device includes a transformer, an uplink cascade connection port, a downlink cascade connection port, and a controller. The controller is enabled when the transformer receives an input electric power, and the controller determines whether the uplink cascade connection port is connected to an uplink transformer device. When the uplink cascade connection port is connected to the uplink transformer device, the controller detects a downlink external transformer device connected to the downlink cascade connection port, reports a detection result to the uplink transformer device, and obtains a control signal from the uplink cascade connection port. The controller converts the input electric power into an output electric power according to the control signal and the transformer.Type: GrantFiled: June 29, 2017Date of Patent: May 28, 2019Assignee: Wistron CorporationInventors: Yuan-Tai Chen, Chia-Hao Liang

Patent number: 8943649Abstract: A hinge includes a pivot, two connection members pivotally connected by the pivot, a first magnetic part connected to one of the connection members, a second magnetic part moveably disposed relative to the first magnetic part and kinetically connected to the other one of the connection members, and an adjustment part kinetically connected to the other connection member and urging against the adjustment part. The magnetic moment of the second magnetic part is opposite to that of the first magnetic part. When the two connection members rotate relatively, the other connection member drives the adjustment part and the second magnetic part to rotate relative to the first magnetic part, so as to produce a repulsive moment resisting the rotation and varies with the rotation. A foldable electronic apparatus has the hinge.Type: GrantFiled: July 24, 2013Date of Patent: February 3, 2015Assignee: Wistron CorporationInventors: Yuan-Tai Chen, Shao-Huai Tsai, Kai-Yu Chu, Yu-Han Tsai
