  • Publication number: 20210255270
    Abstract: The present application relates to correction of position data used in a position information collection system, in which measurement points correspond to position data of a mobile body at respective time points and a movement path of the mobile body connects the measurement points in a time series. When the position data produces a movement path of the mobile body which passes through a not-enterable area, the position data is corrected such that the movement path of the mobile body circumvents the not-enterable area without reducing positioning accuracy, by performing position correction operations which include: determining a crossing status with regard to how the movement path crosses the not-enterable area; counting a number of the measurement points within the not-enterable area; and correcting the position data such that the movement path circumvents the not-enterable area.

  • Publication number: 20210008502
    Abstract: It is to intermittently and effectively generate large bubbles in a liquid phase. A bubble generation device 1 intermittently generates large bubbles a2 in a liquid phase. The bubble generation device 1 includes a bubble storing container 3, a pivot 4, and a pair of edge portion receivers 5a, 5b. The bubble storing container 3 stores bubbles a1 generated by a gas supply nozzle 2 in the liquid. The pivot 4 allows the bubble storing container 3 to pivot thereon, thereby releasing the large bubbles a2 from the bubble storing container 3. The pair of edge portion receivers 5a, 5b receives and blocks an edge portion of the bubble storing container 3 to limit pivot of the bubble storing container 3. An inside of the bubble storing container 3 is partitioned by a partition 30 that is installed in an axial direction of the pivot 4.
