  • Publication number: 20160091324
    Abstract: A server acquires location information data and direction information data. The location information data indicates a travel path of vehicles with discrete locations. The direction information data indicates a traveling direction at each location indicated by the location information data. The server generates information about a new travel route that does not exist in the map data, based on off-route location information data indicative of a travel path deviated from travel routes existing in map data. The server estimates partial travel routes indicative of parts of the new travel route, based on the off-route location information data and the direction information data indicative of associated traveling directions of vehicles. The server then estimates the shape of the new travel route, based on the estimated partial travel routes.

  • Patent number: 9297680
    Abstract: An ultrasonic flow meter is equipped with a housing through which a liquid flows, and a pair of detection units disposed on opposite ends of the housing and including acoustic wave transmitting and receiving units capable of transmitting and receiving acoustic wave signals. Paired connecting plugs are connected respectively to both ends of the housing. In addition, a supply passage of one of the connecting plugs, a conduit of the housing, and a discharge passage of another of the connecting plugs are disposed on a straight line. A liquid supplied to the supply passage flows through a passage of the conduit and to the discharge passage. Consequently, a flow rate of the liquid is measured based on the propagation time of the acoustic wave signals, which are transmitted and received by the acoustic wave transmitting and receiving units.

    Abstract: A navigation apparatus includes hierarchically road map data having third-, second-, and first-layer data respectively representing a high, intermediate, and low road rank. The layer data are contiguously disposed in a storage portion in the order of the road ranks. The first- and second-layer data include area data about individual zones into which a region corresponding to the third-layer data is divided. According to a read request designating a bunch of area data, a cached portion of the designated bunch of area data is obtained from a cache area. The remaining portion is obtained from the storage portion such that an address range of the storage portion from the start point to the end point of the remaining portion is collectively read while area data not designated by the read request but positioned between the remaining portion are additionally read.
