  • Publication number: 20240149909
    Abstract: A monitoring plan generation device sets, for monitoring map information corresponding to a monitoring area indicating an entire area monitored by an uncrewed vehicle, an initial value of a time interval at which a corresponding small area needs to be monitored for each small area obtained by dividing the monitoring map information, counts a remaining time for the initial value of the time interval set in accordance with a passage of time, creates action plan information that establishes a movement route of the uncrewed vehicle to give priority to monitoring the small area where there is little remaining time, and sets an initial value to the remaining time of a small area corresponding to an area monitored by the uncrewed vehicle when the uncrewed vehicle has moved on the basis of the action plan information.

  • Patent number: 11571197
    Abstract: An in-tube transit object that is inserted in a tube includes: a coil section formed by winding a wire; and a fiber section attached to an end on one side and an end on the other side in a winding-axis direction of the coil section. The coil section is formed with a large diameter section, through which fiber of the fiber section is inserted, at the end on the one side and the end on the other side, and is inserted in an extending state in the winding-axis direction when the in-tube transit object is inserted into the tube. The fiber section is configured to expand when seen in the winding-axis direction in the case where the in-tube transit object is inserted in the tube and then discharged from the tube, which brings the coil section into a compressed state in the winding-axis direction.
