Abstract: A movement assistance device includes a provided information acquirer that acquires, traffic signal cycle data in which traffic signal data comprised of identification information of a traffic light, which is stored in an SNS server, and an image capture date and time and a lighting duration time of the traffic light is organized for each light color pattern of the traffic light, and that specifies, from the identification information of the traffic light of the traffic signal cycle data, a traffic light which a moving object will pass, and calculates a remaining lighting time which will elapse until the lighting of each light color of the specified traffic light is ended from both the time difference between the image capture date and time of each light color of the traffic signal cycle data and the current time, and the lighting duration time of the traffic signal cycle data.

Abstract: A travel control device 10 includes: an intersection stopped vehicle determining unit 12 that determines whether or not a forward vehicle is a stopped vehicle that is stopped at an intersection, based on distance information from the own vehicle to each forward vehicle acquired by a forward vehicle detection device 1, and distance information to the intersection existing ahead of the own vehicle acquired by a forward intersection distance acquisition device 2; and a vehicle stop position prediction unit 13 that predicts a stop position of the own vehicle at the intersection based on distance information of the stopped vehicle, when the forward vehicle is determined as the stopped vehicle.

Abstract: A method includes: unifying plural types of substitution tables in each of which a substitution source string and a substitution destination string are mapped to each other into a single substitution table; constructing a prefix tree to incorporate the substitution source string registered in the single substitution table, a string in the prefix tree represented by characters of a label assigned to plural branches on route from a root node to a certain node is identical to the substitution source string mapped to the substitution source string; performing addition of a link failure directing from a first node to a second node for all nodes included in the prefix tree under a certain condition; and searching the substitution source string included in the target string by repeating migration between nodes in the prefix tree based on a certain condition to record identification information assigned to a node before migration.

Abstract: Disclosed is a vehicle-mounted communication device that carries out radio communications with a communication device for pedestrians which is carried by a pedestrian, the vehicle-mounted communication device including: a receiver that receives pedestrian information showing whether the pedestrian belongs to a pedestrian group formed of the pedestrian and a plurality of pedestrians in the vicinity of the pedestrian from the communication device for pedestrians; a controller that judges the pedestrian information received by the receiver and issues a command to present pedestrian attention information when the pedestrian information shows that the pedestrian does not belong to a pedestrian group; and an information outputter that presents the pedestrian attention information according to the command from the controller. Therefore, the vehicle-mounted communication device enables the driver to certainly recognize the existence of a pedestrian not belonging to a pedestrian group.

Abstract: Information processing system includes a first certification device which executes a first temporary certification, creates a first temporary certificate, transmits it to an external device, carries out a first formal certification and creates the first formal certificate, a second certification device which executes a second temporary certification based on the first temporary certification, creates a second temporary certificate, transmits it to the external device, carries out a second formal certification and creates the second formal certificate, and a processing device which verifies a validity of the first formal certificate corresponding to the first temporary certificate and a validity of the second formal certificate corresponding to the second temporary certificate from the user, in response to a information processing request from the user and determines to execute the information processing corresponding to the information processing request based on the verification result.

Abstract: An information providing apparatus makes a decision, when an information providing deciding unit decides that driving support information is to be provided, as to whether the output of the voice information about the driving support information responding to a command from the information providing deciding unit and the output of the voice information about route guidance info nation responding to a command from a route guidance unit overlap each other or not, and controls, when they overlap each other, the output of voice information by an information providing output unit in such a manner as to prevent the output of the voice information about the driving support information from overlapping with the output of the voice information about the route guidance information.

Abstract: An arithmetic operation unit receives a request to update a first data group during restoration using first history information and generates second history information indicating a history of updates. The arithmetic operation unit predicts a time taken until completion of restoration using the second history information on the basis of an amount of the second history information. The arithmetic operation unit compares the predicted time with a threshold and limits at least part of updates of the first data group during the restoration using the second history information on the basis of the comparison result.
