Patent number: 11924513Abstract: Disclosed are a display apparatus and a method for displaying a user interface. In response to a preset instruction, the display apparatus acquires local images to generate a local video stream, plays a local video picture, and displays a graphic element for identifying a preset expected position in a floating layer above the local video picture. When the moving target exists in the local video picture and an offset of a target position of the moving target in the local video picture relative to the expected position is greater than a preset threshold value, a prompt control for guiding the moving target to move to the expected position is presented in the floating layer above the local video picture according to the offset of the target position relative to the expected position.Type: GrantFiled: November 18, 2021Date of Patent: March 5, 2024Assignee: JUHAOKAN TECHNOLOGY CO., LTD.Inventors: Guangqiang Wang, Xiaochun Xu, Zhezhe Liu, Xiangsheng Wu, Yuanyuan Li, Yinyang Chen, Yao Xie, Fanwen Zhang

Patent number: 10658891Abstract: Embodiments describe a motor. The motor includes a stator, and a rotor, which is arranged within the stator. An end part of at least one air-gap slot of the rotor has an offset with a predetermined distance and/or a predetermined angle relative to a main body part adjacent immediately to the end part. With the offset of a predetermined distance and/or a predetermined angle configured at the end part of at least one air-gap slot of the rotor, ripple torque of the motor is effectively lower down while complexity of the motor, stator or rotor will not be increased.Type: GrantFiled: December 28, 2016Date of Patent: May 19, 2020Assignee: DANFOSS (TIANJIN), LTD.Inventors: Wanzhen Liu, Li Yao, Yan Lin, Guangqiang Liu, Zhenyu Wang, Meng Wang, Weiping Tang

Patent number: 10389216Abstract: A stator, a motor and a compressor are provided. The stator includes a stator iron core and a winding. The stator iron core includes: an annular yoke; multiple stator teeth, near ends of the stator teeth being fixedly adjacent to an inner surface of the yoke and projecting inward towards the center of the stator iron core along a radial direction of the yoke, remote ends of the stator teeth that face inward along the radial direction defining a center hole for accommodating a rotor, and the stator teeth being spaced from each other in a circumferential direction; and multiple stator slots, each stator slot being defined between two neighboring stator teeth. The winding is wound around the stator teeth and operable for generating a rotating magnetic field. The yoke has at least two cut edges at an outer periphery thereof, disposed asymmetrically relative to the center.Type: GrantFiled: December 28, 2016Date of Patent: August 20, 2019Assignee: Danfoss (Tianjin) Ltd.Inventors: Weiping Tang, Li Yao, Wanzhen Liu, Guangqiang Liu, Yan Lin, Zhenyu Wang, Meng Wang
