  • Patent number: 10928201
    Abstract: According to one embodiment, a position estimation device includes an acquirer that acquires wheel rotation information as information on rotation of wheels of a mobile structure and object information on an object, and an estimator that estimates a position of the mobile structure by calculating a directional deviation of a mobile structure as change in a direction of the mobile structure from the wheel rotation information and a predetermined direction parameter and calculating the direction of the mobile structure from the directional deviation of the mobile structure, and corrects the direction parameter on the basis of the directional deviation of the mobile structure and an object directional deviation as variation in a direction of the object relative to the mobile structure by calculating the object directional deviation from the object information.

  • Patent number: 10656892
    Abstract: When virtual printers are collectively registered with a plurality of print services through one operation, a virtual printer may be registered also with print services not utilized. In the present invention, by acquiring information regarding print services, provided by a plurality of print services, and information regarding virtual printers registered with the print services, it is determined, on a basis of the information regarding the virtual printers and a printer ID of the local printer, whether or not the local printer has been registered as a virtual printer with the print services. Information regarding the print service with which the local printer is determined not to have been registered is displayed, and when instructed by a user to register the local printer with the displayed print service as a virtual printer, the local printer is registered as the virtual printer with the instructed print service.

  • Patent number: 10402135
    Abstract: In the case of displaying, as a list, information pieces on virtual printers registered in multiple respective printing services, the user may become confused when choosing a printer if virtual printers that correspond to a printer are displayed as different printers, consequently reducing user convenience. The present invention relates to searching for virtual printers registered in multiple respective printing services and generating a printer list that displays, as a group, virtual printers corresponding to a printer among the virtual printers thus found, on the basis of printer identifiers of the virtual printers.
