  • Publication number: 20200400444
    Abstract: The disclosed computer-implemented method may include determining that one or more personal mobility vehicles would provide more benefit to the dynamic transportation network if the personal mobility vehicles were relocated and creating a dynamically generated tour for at least one user that ends with a personal mobility vehicle deposited by the requestor at a more beneficial location. In some embodiments, the dynamically generated tour may include one or more geographic points of interest that are expected to be relevant to the user. In some examples, the dynamically generated tour may be generated with various constraints such as time, distance, and battery usage. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 10264952
    Abstract: A method for positioning an endoscope involves installing an auxiliary positioning device on a robot arm, coinciding a terminal of a docking member of the auxiliary positioning device with a spherical remote center of motion defined by the robot arm, inserting and fixing the endoscope inside the auxiliary positioning device, removing the docking member of the auxiliary positioning device so that a terminal of the endoscope coincides with the spherical remote center of motion of the robot arm, and then inserting the endoscope into a body cavity catheter for finalizing positioning. Thereby, the method helps to save time used for preoperative preparation and provides more precise positioning, without using any additional positioning tools to approach the body cavity, thereby reducing the risk of infection.

  • Publication number: 20180152061
    Abstract: A stator comprises multiple, stacked laminations, which collectively define a core having a number of posts arranged circumferentially about the core. Each post extends into two prongs defining a first slot between the prongs. The spacing between each posts and its two prongs defines a second slot having a radially inner and outer slot. The outer slot geometry has an increasing width extending radially outward from the radially inner end, and transitioning to a decreasing width extending to the radially outer end.
