Patent number: 11960296Abstract: A method executable by an autonomous mobile device includes moving in a work environment, obtaining environmental data acquired by a sensing device, and determining whether the sensing device is in a suspected ineffective state based on the environmental data. The method also includes based on a determination that the sensing device is in the suspected ineffective state, rotating at a same location for a first predetermined spin angle. The method also includes obtaining an estimated rotation angle based on one or more motion parameters acquired by a dead reckoning sensor, comparing the estimated rotation angle with the first predetermined spin angle, and based on a determination that a difference between the estimated rotation angle and the first predetermined spin angle is greater than a first predetermined threshold value, executing escape instructions to move backwardly for a first predetermined distance and move along a curve or a folded line.Type: GrantFiled: August 16, 2021Date of Patent: April 16, 2024Assignee: QFEELTECH (BEIJING) CO., LTD.Inventors: Shuailing Li, Wulin Tian, Huizhong An, Xin Wu, Yiming Zhang, Zhen Chen

Publication number: 20230404434Abstract: According to the techniques herein, one or more sensors coupled to an aligner are used to sense one or more physical qualities of the aligner to determine whether the physical qualities indicate that the aligner material has relaxed and has, e.g., reduced the force systems applied to teeth and/or that the teeth movement for the stage has slowed down. The sensors may provide a signal that represents whether or not the physical qualities fall below a threshold value. A treatment plan may be modified if needed. These techniques have the potential to make treatment plans faster and more effective by speeding up some stages while making sure some, perhaps other, stages are implemented only after the teeth are near the appropriate position.Type: ApplicationFiled: August 30, 2023Publication date: December 21, 2023Inventors: Huizhong LI, Andrew JANG, Michael Christopher COLE, Yuxiang WANG, Jun SATO, Allen R.
