Abstract: The content output device includes an information acquisition unit, a content generation unit and an output unit. The information acquisition unit acquires driving state information which is information related to a current driving state of a vehicle. The content generation unit acquires one or more content elements corresponding to a trigger condition, from among a plurality of content elements combinable with each other, when the driving state information satisfies the trigger condition, and generates an output content using the acquired content elements. The output unit outputs the output content.

Abstract: A server device efficiently acquires information of a surrounding area of a movable body for updating map information while suppressing communication load. Condition information indicating a condition of autonomous driving is received from a first movable body capable of autonomous driving based on a state of a surrounding area of the first movable body and a map, and a request for state information is transmitted to a second movable body capable of transmitting the state information indicating a state of a place where the first movable body has moved, and when the received condition information indicates that the autonomous driving has been possible, transmission of the request is prevented.

Abstract: A first acceleration sensor is arranged on a crank mounted to a crankshaft so as to be located at a position away from the crankshaft by a distance r1, and the first acceleration sensor detects acceleration a1 in a direction parallel to a longitudinal direction of the crank. A second acceleration sensor is arranged on the crank mounted to the crankshaft so as to be located at a position away from the crankshaft by a distance r2 different from the distance r1, and the second acceleration sensor detects acceleration a2 in a direction parallel to the longitudinal direction of the crank. A measurement module control part calculates information regarding a rotation angle of the crank based on a1, a2, r1, and r2.

Abstract: There is provided an information recording medium that reduces operation of shifting information backward or putting information forward closer together upon recording/deleting/dividing information to facilitate processes of recording/deleting/dividing information. An information recording medium records Programs 1 composed of image data, etc., UPGR 3 that refers to at least a part of the Programs 1, PGRG 5 that refers to the UPGR 3, a PGRM that collectively records the UPGR 3 and reference information thereof, and a PGRGM that collectively records the PGRG 5 and reference information thereof. When recording the UPGR 3, the information recording medium refers to the reference information contained in the PGRM, and when invalid reference information or reference information giving no reference to any UPGR 3 is present, records the UPGR 3 using the reference information.

Abstract: In a content delivery method in a P2P network, a node managing a content causes a downstream node to manage a volume of a divided content; this volume is according to a situation of the downstream node (for example, a line speed to which a node is connected). A node managing a content holds, as management information, partial information of the divided content managed by its own node, and location information indicative of a location at which a content itself is presented. Next, when a content transfer request is sent to a node managing a content, the node accesses a content holding node in accordance with the held location information, downloads a volume of a divided content indicated by the partial information, and uploads the volume of the divided content to a node that sends the content transfer request.

Abstract: A network configuration management method has a step of sequentially propagating a network ticket that a network configuration monitoring node has issued to each of a predetermined number of nodes (predetermined number of nodes<number of all nodes) from the node to the node so as to cover all nodes of a P2P network, a step in which each of the nodes having received the network ticket plays a role to investigate the node adjacent to its own node, creates information on a network configuration around its own node, and transmits the information on the network configuration created by each of the nodes to the network configuration monitoring node. Furthermore, in the network configuration management method, the network configuration monitoring node grasps the configuration of the entire P2P network from the collected information on the network configuration.
