  • Patent number: 9983022
    Abstract: An onboard control device that is installed at a vehicle acquires land mark information including position information of a landmark which can be recognized on a road in which the vehicle is estimated to travel by a camera, a landmark image for recognition, a recognition evaluation value that represents ease of the recognition successfully performed and so on, and selects a landmark to be a subject for recognition based on the recognition evaluation value included in the landmark information. The onboard control device further evaluates the recognition results of the landmark to be a subject for recognition, and transmits the recognition results to the server with the landmark image recognized by the camera. The server aggregates the recognition evaluation results of the landmark and the recognized images and reflects them in the recognition evaluation values for the landmark information and landmark images to be transmitted to the onboard control device.

  • Patent number: 9310489
    Abstract: The present invention provides a transmitter comprising: a plurality of antennas; and a radio transmitting part transmitting from each of the antennas a positional information signal containing the same positional information, the positional information being transmitted from the antennas through channels which are different between the antennas. The transmitter enables prevention of the positioning error and the positioning time from increasing by solving problems of null points and signal interferences, problems relating to a positional information transmitter disposed indoors, in a positioning system for acquiring a current position both indoors and outdoors.

  • Patent number: 8121066
    Abstract: One objective of the present invention is to determine a location for a relay terminal in a radio network, without preparatory surveying a radio status, and to arrange the relay terminal at the location. Another objective is to provide a method for retrieving the arranged relay terminal. When a relay terminal is to be arranged, the relay terminal transmits a survey packet to examine the quality of communication with a communication terminal or other relay terminal. Where a location is appropriate, the relay terminal gives a notice. The arranged terminal relays communication. Further, when the relay terminal is to be retrieved, the relay terminal carried by a user transmits a retrieval packet to the arranged relay terminal, which notifies the user of its presence by light, sounds, or returning a packet. In this manner, a single relay terminal provides functions of arrangement, relay and retrieval.
