  • Patent number: 11244266
    Abstract: The incident response assisting device includes: an incident extraction unit, a response procedure creation unit, and a screen display unit. The incident extraction unit performs an incident extraction process on an alert indicating that an incident has occurred in a monitored object and on log data of the monitored object, to extract incident information. The response procedure creation unit creates an incident response procedure corresponding to the incident on the basis of the incident information and a response procedure template. The screen display unit selects a display range from the incident response procedure in accordance with a progress status of response and displays the display range as a display response procedure. The incident extraction process is composed of a series of comparison processes in which a content of a comparison process to be subsequently performed is changed in accordance with a result of a previously performed comparison process.

  • Patent number: 10056171
    Abstract: Protrusion portions and recess portions are formed on a metal layer. The protrusion portions are repeatedly formed in a lattice shape at a pitch of P. Similarly, the recess portions are repeatedly formed in the lattice shape at the pitch of P. The protrusion portions and the recess portions are arranged in the same arrangement direction and arranged shifted to each other by half the pitch in the arrangement direction. The protrusion portions and the recess portions are formed independently of each other without contacting each other. In order to allow a multilayer tape to reliably follow the bending deformations of a power cable (submarine cable) in all directions, in an arbitrary cross-section taken in the longitudinal direction of the multilayer tape (in the axial direction of an impermeable layer), the protrusion portions or the recess portions are necessarily arranged at predetermined intervals.
