  • Publication number: 20230362182
    Abstract: An anomaly detection device is provided with a learning unit that generates a detection model using a communication log during normal operation of a communication apparatus as learning data and an anomaly detection unit that detects anomaly of the communication apparatus using the generated detection model. The anomaly detection device is further provided with a data acquisition unit that acquires a communication log (second communication log) generated during a predetermined period later than a first communication log and a determination unit that instructs relearning using the second communication log when there is difference information between the learning data (first communication log) of the current detection model and the second communication log and when the number of pieces of additional information (information on the additional flow) or the number of pieces of deletion information (information on the delete flow) included in the difference information satisfies predetermined evaluation criteria.

  • Patent number: 11805142
    Abstract: A communication system including an operational network including a host and a learning and detection server, and a staging network including a host of the same type as the host, a test execution server, and a learning and detection server. The test execution server performs a communication test by transmitting test communication in a normal state to the host and receiving communication performed by the host. The learning and detection server learns the communication of the host, generates an initial model for detecting an anomalous communication of the host, and transmits the initial model to the learning and detection server. The learning and detection server learns the communication of the host and generates a model for detecting an anomalous communication of the host, while monitoring the communication of the host using the initial model received from the learning and detection server.

  • Patent number: 8371412
    Abstract: A saddle riding type vehicle includes a sensor that generates a signal, a moving member that moves a movable portion of the sensor and a coupling member that couples the moving member to a change pedal. The change pedal, the coupling member, the moving member and the sensor are arranged sequentially alongside one another along a sub-frame. The sub-frame is an existing member constituting a part of a vehicle body frame. Thus, base plates dedicated to the moving member, the sensor and the like can be eliminated.

  • Patent number: 8336875
    Abstract: A bill discriminating and counting apparatus in which a plurality of bills with different sizes are filled between side hopper members and fed into a transport path by a feeding mechanism. The feeding mechanism comprises a plurality of rollers disposed in a bilaterally symmetrical state. The plurality of rollers are arranged so that, when a distance between the side hopper members is adjusted according to the longitudinal dimension of a bill with the maximum dimension in the longitudinal direction and a bill with the minimum dimension in the longitudinal direction is disposed at a position where the bill is brought into contact with one of the side hopper members, at least a part of the rollers installed on the opposite side of the side hopper member where the bill is brought into contact therewith is brought into contact with the bill. Also, the feeding mechanism comprises a guide member guiding the bill to the inlet of the transport path.
