  • Patent number: 10885287
    Abstract: An article management system includes multiple reader devices that read the RFID tags attached to the articles. Moreover, a central terminal partitions an article management area into multiple middle areas that are in turn partitioned into small areas, and then causes reader devices arranged in two or more small areas to work in a predetermined order for each small area, to read information of the RFID tags. The range of radio wave interference distance assumed for a reader device in a first middle area partially overlaps with a second middle area. Thus, when causing the reader devices arranged in the first middle area to work in order, the central terminal controls a reader device in the second middle area that lies outside the range of radio wave interference distance from a reader device working in the first middle area.

  • Publication number: 20200403544
    Abstract: In the work device that has a self-holding circuit (61) maintaining power supply from a power supply circuit (12) by output from a microcomputer (40) and has a structure in which stopping output to the self-holding circuit (61) causes interruption of power supply from the power supply circuit (12) to the microcomputer (40), the firmware of the microcomputer (40) is made to be rewritable and a power holding unit (condenser (C1)) for temporarily continuing power supply to the microcomputer (40) is provided, thereby realizing a so-called “off-delay timer function” for restarting the microcomputer (40). This configuration enables maintenance of power to the microcomputer (40) after update of the firmware even in a work device that cannot be restarted once power has been turned off unless trigger operation is performed, thereby enabling automatic restart of the microcomputer 40 after resetting is enabled.

  • Publication number: 20200380128
    Abstract: A signature generating device (2) includes a collecting unit (11) configured to collect threat information, an extracting unit (21) configured to extract attack data from the threat information collected by the collecting unit (11), and a generating unit (31) configured to generate a signature on the basis of the attack data extracted by the extracting unit (21). When plural pieces of attack data having a common character string are extracted by the extracting unit (21), the generating unit (31) tentatively generates a signature including the common character string, evaluates whether a tentatively generated signature includes a character string used in non-attack data, and when the tentatively generated signature includes the character string used in the non-attack data, removes the character string from the tentatively generated signature to generate a signature.
