  • Patent number: 10798149
    Abstract: When a part already transmitted to an object storage is updated by a file system management section while a plurality of parts are being transmitted to the object storage, a file transfer section requests the object storage to generate a temporary object that is a temporarily generated object containing the transmitted and updated part by combining the parts transmitted before update, re-splits a file into a plurality of parts so that the transmitted and updated data and not-transmitted data are handled as parts different from transmitted and not-updated data, and transmits the part containing the transmitted and updated data or the part containing the not-transmitted data to the object storage.

  • Patent number: 10560585
    Abstract: A server network includes a central server and store servers. Each of the store servers is connected to one or more receipt printers. The central server selects one or more store servers to which image data of an image to be added to a receipt are distributed, and transmits the image data along with condition data to the selected store servers, which are then distributed to receipt printers. Receipt printers that received the image data print one or more receipts with the additional image upon the conditions being met, and transmit content data of each printed receipt to the corresponding store server. Each of the selected store servers generates a receipt issue log based on the content data, and transmits receipt issue logs that accumulated therein to the central server. The central server calculates an amount of exposure of the additional image based on receipt issue logs.
