Abstract: A high-definition map building method includes determining a key node describing information about a key position of a lane attribute change, determining a key node layer based on a position of the key node and an attribute of the key node, and determining a high-definition map based on a navigation map and the key node layer. The navigation map provides road-level navigation information, and the high-definition map provides lane-level navigation information.

Abstract: A pressurized nebulizer includes a nozzle, a peristaltic pump, and an elastic braided hose. The peristaltic pump includes a fixing part, a mating part, a rotating base and a roller. When the mating part and the fixing part are in a closed state, the elastic braided hose is arranged between the mating part and the fixing part, and between the mating part and the roller. An output end of the elastic braided hose is connected with the nozzle. The roller in the working stroke has a limit position of extruding the elastic braided hose to a limit state, a minimum clearance formed between the roller and the mating part is 1.5 T?P?1.9 T, where T denotes a unilateral wall thickness of the elastic braided hose, and P denotes the minimum clearance. The nebulizer can avoids liquid contact contamination, provide a stable output and have accurate accuracy.

Abstract: A system for collecting information regarding a flight restriction region includes one or more processors and a non-transitory computer readable storage medium storing instructions that, when executed by the one or more processors, cause the one or more processors to individually or collectively receive an input specifying a location of the flight restriction region from a user via a user input device, obtain information associated with the flight restriction region from one or more external data sources based on the location, and determine a space of the flight restriction region based on the information associated with the flight restriction region.

Abstract: A system for collecting information regarding a flight restriction region includes one or more processors and a non-transitory computer readable storage medium storing instructions that, when executed by the one or more processors, cause the one or more processors to individually or collectively receive, from a user input device, an input designating one or more parameters of the flight restriction region. The one or more parameters include a location of the flight restriction region. The instructions further cause the one or more processors to determine a space for the flight restriction region based on the one or more parameters.

Abstract: Systems and methods are provided for collecting information regarding flight restriction regions. The information regarding flight restriction regions may be approved of, or the identity of a user inputting such information may be verified. The designated flight restriction regions may be displayed on a three-dimensional map and be utilized by UAVs, for example, in conjunction with flight response measures.

Abstract: The present disclosure provides a method and apparatus for processing pushed information, an apparatus and a non-volatile computer storage medium. In embodiments of the present disclosure, the pushed information is obtained according to at least one of the user's user attribute and the user's user position, then the pushed information is sorted according to the operation data of the pushed information so that first N pushed information can be presented to the user, and N is an integer larger than or equal to 1.
