  • Patent number: 11592833
    Abstract: One variation of a method for updating a localization map for a fleet of autonomous vehicles includes: selecting a set of roads including a first subset of road segments associated with existing incomplete scan data and a second subset of road segments associated with a monitoring request from an external entity; during a passenger period at the autonomous vehicle, autonomously transporting passengers according to a series of ride requests; during a mapping period succeeding the passenger period at the autonomous vehicle, autonomously navigating along the set of road segments, recording a first series of scan data representing surfaces proximal the first subset of road segments, and recording a second series of scan data representing surfaces proximal the second subset of road segments; updating the localization map based on the first series of scan data; and serving the second series of scan data to the external entity.

  • Patent number: 10586670
    Abstract: Disclosed is a wireless diagnosis system power supply, which is not connected with an external power supply, and comprises a shell (1), a battery pack (2) provided within the shell, an electrical module (3) connected with the battery pack to adjust the voltage and the current, and a cable handle (4) connected with the electrical module. The power supply provides independent power supply directly without connecting with an external power network, and achieves a reasonable arrangement, a compact structure, a small size, a long service life, power saving, safety and reliability, convenience in clinical use, and high utilization rate of clinic space; and the whole system is portable and easy to install.
