  • Patent number: 11988952
    Abstract: A lens driving device and a driving method thereof are provided. The lens driving device includes a lens frame, a magnetic group, a driving element group and a control device. The lens frame carries at least one optical element. The magnetic group includes a plurality of pairs of magnetic elements. The driving element group includes at least two coils. The control device supplies power to the driving element group so that the lens frame is driven by the driving element group to move. The driving element group is disposed on the lens frame, and the amount of the lens frame is equal to that of the driving element group. The control device in a first driving state supplies the power to the coils in sequence so that the driving element group is moved from a pair of magnetic elements to another pair of magnetic elements.

  • Publication number: 20220308593
    Abstract: Transfer apparatuses and methods thereof are provided. First, a laser ranging unit is used to perform a first scanning ranging operation for an environment to obtain a laser scanning ranging result of the environment. Then, a displacement calculation unit is used to detect displacement information of a transfer apparatus. According to the laser scanning ranging result and the displacement information, map information of the environment is established and positioning information of the transfer apparatus in the environment is determined, wherein the map information includes information of a charging device. The map information and the positioning information of the transfer apparatus is transmitted to an application device via a connection interface.
