  • Patent number: 11913459
    Abstract: A fan assembly includes a fan cover. The fan cover is provided with a vane assembly and is fixed by a rotating shaft, which includes blades and magnetic vanes arranged along its outer contour. The coils are evenly arranged along the fan cover. The magnetic rotor blade and the alternating magnetic field generated by the coils can drive the blades to rotate, and the rotation speed can be adjusted by changing the speed of the alternating magnetic field. The coils are fixedly installed in the outer cover of the fan, and the vane assembly is only installed by the rotating shaft, which can easily disassemble from the vane assembly. The structure is simple and has higher reliability. So, it is not easily damaged, and has a longer service life. The fan assembly can be completely waterproof, so that the product can be used in high humidity and even water.

  • Publication number: 20210362758
    Abstract: Techniques for injecting a vehicle into a high speed transportation system are described. A travel request is received from a user. The user is determined to be authorized to travel using the high speed transportation system, based on a profile associated with the user. An injection portal for the user to enter the transportation system is identified. One or more instructions for the user are provided, relating to the injection portal. A vehicle associated with the user is identified at the injection portal. Characteristics of the vehicle are sensed at the injection portal, including a center of gravity of the vehicle. The characteristics are determined to satisfy threshold values, and the vehicle is authorized for travel in the transportation system. A vehicle profile is generated. The vehicle profile is transmitted to a second controller associated with the transportation system. The vehicle is injected into the transportation system.
