  • Patent number: 10922632
    Abstract: A client device accepts event information for which a people flow prediction is to be performed from a user and the client device inputs the accepted event information to a people flow prediction device. The people flow prediction device outputs a result of people flow prediction responsive to the input event information to the client device and the client device displays the result of people flow prediction to the user. The people flow prediction device performs a people flow prediction by temporally and spatially allocating an event attendance which has been input from the client device to pathways, each connecting a transport facility at which a people flow originates and an event site. Consequently, it is possible to predict a flow of people who attend an event or the like, the people flow differing from that in an ordinary situation, without need to input real-time data.

  • Patent number: 10846282
    Abstract: In a behavior characteristic amount analysis system, a necessary storage capacity is saved and reduced upon a statistical process performed on a large amount of measured data from a sensor or the like and the analysis of characteristics of a target to be measured. A behavior characteristic amount analyzing server includes a central processing unit and a storage device. The storage device holds a sensor table group of sensor tables holding sensor data from the sensor, and a pivot table of pivot tables aggregated based on the sensor table group and one or a combination of the moving object, time, and a location. The central processing unit generates the pivot tables based on information of the sensor tables for each of predetermined time periods, causes the generated pivot tables to be stored in the storage device, and deletes the sensor tables used for the generation of the pivot tables.

  • Patent number: 10368191
    Abstract: A confined space estimation system, and a confined space estimation method capable of accurately confirming a confined space formed in the event of a disaster, estimates a confined space comprising a storage device which stores information indicating a geographical space, and a processor which divides the geographical space into grids. Based on location information sent from a terminal, the processor periodically aggregates a number of terminals within the grids or a number of terminals that passed through boundaries between the grids, extracts grids or boundaries in which the aggregated number of terminals is a predetermined number and in which there is no change in the aggregated number of terminals, determines whether the extracted grids or boundaries can be linked to form an annular shape, and, if the annular shape can be formed, estimates a geographical space configured from the grids within the formed annular shape as the confined space.

  • Patent number: 8538759
    Abstract: It is provided a speech recognition system installed in a terminal coupled to a server via a network. The terminal holds map data including a landmark. The speech recognition system manages recognition data including a word corresponding to a name of the landmark, and sends update area information and updated time to the server. The server generates, when recognition data of the area of the update area information sent from the terminal has been changed after updated time, difference data between latest recognition data and recognition data of the update area information at a time of the updated time, and sends the generated difference data and map data of the update area information to the terminal. The terminal updates the map data based on the map data sent from the server. The speech recognition system updates the recognition data managed by the terminal based on the difference data.

  • Patent number: 8156076
    Abstract: Disclosed herewith is a terminal for receiving data distributed from a host computer. The terminal includes a database for storing data distributed from the host computer and a schedule manager for managing the schedule of the terminal. Upon receiving an update request for the data stored in the database, the terminal extracts a time band in which the usage frequency of the terminal is kept low as an updatable time through the schedule manager and sends an update request to the host computer in response to the received request. The terminal calculates a processing time required to update object data, as well as a value denoting the usefulness of the object data according to the update information received from the host computer and including the object data, then decides a processing order for the object data according to the processing time and the usefulness value calculated respectively for the object data, thereby updating the data stored in the database according to the decided processing order.
