  • Publication number: 20180182046
    Abstract: A user device may transmit a request for electricity via a wire to a smart device, where the request includes the universal unique identifier (UUID) of the user device. Upon the reception of the UUID, the smart device may enable an electricity flow to the user device. The smart device may further measure the electricity amount of the electricity flow enabled to the user device based on the UUID. Based on the UUID, the smart device may measure the electricity amount enabled to a specific user device. Consequently, the calculation of electricity cost may be implemented for a specific user device. In some embodiments, the smart device may calculate the electricity cost for different user devices independently. Therefore, the calculation of electricity cost may be more accurate and smart.

  • Publication number: 20180174451
    Abstract: According to a method for selecting a path, the vehicle may receive driving condition of an area from a server, where the driving condition indicates that the area comprises a trouble area. Based on the driving condition of the area, the vehicle may calculate a first path and a second path, each of which is from a first point to a second point. The vehicle may obtain an effect value on vehicle driving associated with a change of weather. Based on the effect value and some other information, the vehicle may calculate a first weighted value for the first path and a second weighted value for the second path. Based on the first weighted value and the second weighted value, the vehicle may select a path. Because the effect value is used to select a path, the path selection in this embodiment may be associated with the change of weather.

  • Publication number: 20180176070
    Abstract: The disclosure relates to technology handling events in a distributed computing environment. Events comprising a function executable by an instance are received from an event queue. The received events are mapped to an instance in a pool that executes a corresponding function. When it is determined that the instances in the pool are at least one of unavailable and do not include the function corresponding to the event, a new instance is created in the pool, where the new instance includes the function corresponding to the event. Instances in the pool may be terminated when frequency of occurrence patterns of the event with a corresponding function indicate the event is occurring less frequently such that fewer instances are required to execute the corresponding function. Otherwise, the events are dispatched to the appropriate instance in the pool for execution.
