Abstract: A vehicle communication system includes a central device and an on-vehicle device. A path determiner of the central device determines an information transmission path between a plurality of vehicles for consolidating information in a vehicle that performs a wireless communication with a terrestrial communication device out of the vehicles based on at least operating information on the vehicles. An on-vehicle communicator of the on-vehicle device acquires the information transmission path directly from the central device via the terrestrial communication device or indirectly from the central device via the terrestrial communication device and a second vehicle, and transmits and receives predetermined information to and from the terrestrial communication device or the second vehicle based on the acquired information transmission path.

Abstract: A system of an embodiment includes an analysis device that includes a first database for storing information for identifying a person and an object inside an image, performs, using the information, image analysis of footage taken by cameras installed in locations, associates an identified person, an object carried by the person, and a seat location with each other, determines, based on a user facial image and the user's seat location, whether a person associated with the seat location is the actual user, and outputs a verification result; and a device that includes a second data base for storing a seat, a facial image and identifying information of each user, transmits information on the user's seat and the facial image to the analysis device, receives the verification result from the analysis device, and transmits an alert to a predetermined point of contact.

Abstract: According to an aspect, a network system comprises a ring-type network, and a master transmission apparatus. The master transmission apparatus includes blocking unit, conversion unit and transmission unit. The blocking unit prohibits relay of the transmission frame received through a first virtual transmission line and a second virtual transmission line. The conversion unit changes transmission path information included in the transmission frame from the first virtual transmission line to the second virtual transmission line. The transmission unit transmits the transmission frame including the transmission path information changed by the conversion unit.

Abstract: A train control device includes a first acquisition unit for acquiring a change history of open block numbers as the number of blocks existing between a present train and a leading train, a setting unit for setting a brake pattern having a starting point coinciding with an end point of a block existing just behind a block occupied by the leading train, and a calculating unit for calculating a time taken for the leading train to come out from the block existing just behind the block occupied by the leading train and for calculating, as a target speed, the highest speed available within a range not conflicting with the brake pattern.
