  • Patent number: 11756423
    Abstract: An automatic vehicle positioning management system includes an on-vehicle apparatus and a portable device. The on-vehicle apparatus, installed on a vehicle, acquires a first location of the vehicle through wireless positioning. The first location is sent to the portable device which acquires a second location of the vehicle through GPS. When multiple vehicles form a fleet, each vehicle respectively sends its first and second locations to a server through its portable device. The second location of each vehicle is corrected by operations of point error analysis, image overlay and point error correction, so that the fleet can be managed more precisely.

  • Patent number: 11459354
    Abstract: The present invention provides improved processes for purifying liraglutide. Liraglutide is purified via two sequential RP-HPLC purifications followed by a salt-exchange step, where a pH is kept constant in the first and second purification steps. In particular, the processes utilize a halogenated solvent in a sample preparation step, which provides better solubility and an environment suitable for decarboxylation for crude liraglutide prior to a RP-HPLC purification.

  • Patent number: 11391349
    Abstract: A compact angular actuator allows for angular displacement between a first section and a second section. The first section comprises a cam that is circular in cross section and has a wedge-shaped face. The second section comprises two or more constraint components that are in contact with the face of the cam. A hinge joins the first section and the second section in proximity with one another. As the cam is rotated about an axis that is perpendicular to and extends through a center of the circular cross section, the position on the face that the constraint components are in contact with changes. As a result, a force is imparted between the first section and the second section, changing the angular displacement between the two. The actuator fits within a compact volume and allows for precise controlled angular displacement, while allowing that displacement to be maintained without power consumption.
