摘要： Disclosed is a method for real-time object locating and mapping, including: 1) performing real-time locating for a moving object in the range of movement; 2) updating a geomagnetic field map in the range of movement of the object in real time according to the locating of the moving object; 3) locating the next position of the moving object according to the updated geomagnetic field map; and repeating steps 2) and 3) until the object stops moving. A device for real-time object locating and mapping is also disclosed. The present application can solve the problem of real-time object locating and accurate geomagnetic field mapping without an indoor priori magnetic field map.

摘要： Disclosed is a mobile self-service method and a system including a movable service terminal configured to acquire, verify and parse user data to obtain flight number information about a user; a background service system configured to interact with the movable service terminal and provide service data in response to a request sent from the movable service terminal. The terminal is further configured to interact with the background service system to verify the flight number information, confirm a corresponding flight, establish real-time indoor positioning information about the movable service terminal, and provide a prompt for navigation from the current position to a corresponding boarding gate or a specified position according to the service data and the real-time positioning information. The present invention can provide personalized flight information, positioning and navigation prompts to passengers waiting for flights in airports, provide path planning and estimate the required time.

摘要： A method and system for locating an object are disclosed. The method comprises generating a plurality of sampling points in an activity area map for an object; obtaining a conditional probability density of the object's locating at the plurality of sampling points according to an initial electromagnetic field intensity of the plurality of sampling points and a current electromagnetic field intensity of the object to be located; conducting resampling and updating for the sampling points according to the conditional probability density; and determining a position of the object to be located based on coordinate values of sampling points after the updating. The present invention can improve the accuracy of the locating or tracking on an indoor object.

摘要： Disclosed are a method system, and device of updating local software. The method comprises: broadcasting a broadcast message for updating local software to multiple client ends; determining whether a response message about existence of the update software is received, updating local software through the client end sending out the response message, or through a remote server if no response message is received. Accordingly, restriction on transmission speed by OTA server in software update process and congestion in data transmission process can be avoided, thus improving downloading speed and facilitate a simultaneous update of software for a mass of devices.
