  • Patent number: 11644324
    Abstract: The present invention identifies a danger spot effectively. In a navigation device 10, a danger spot identification unit 34 identifies a jump-out danger spot on the basis of past information which is acquired by a past information acquisition unit 24 and indicates a situation of a jump-out accident in the past, and surrounding information which is acquired by a surrounding information acquisition unit 32 and indicates a surrounding situation of a vehicle. Here, the past information includes surrounding facility identification information (information related to an identification planimetric feature) used for identifying a jump-out danger spot and information related to a jump-out object. As a result, the danger spot identification unit 34 can identify a danger spot of a jump-out which can occur due to a planimetric feature (a facility) in a jump-out accident. Therefore, the navigation device 10 can identify a jump-out danger spot effectively.

  • Patent number: 11494383
    Abstract: When a DBMS receives a suspend instruction in which a suspend completion time of query processing is a future time and between receipt of the suspend instruction and the suspend completion time, if there is a target object (at least a processing object whose execution is in progress upon receipt of the suspend instruction) whose predicted completion time is at or precedes the suspend completion time, the DBMS changes the state of the target object to a state signifying a snapshot suspend. If there is a processing object whose state signifies a snapshot suspend, the DBMS executes the processing object at or before the suspend completion time.
