  • Publication number: 20150026180
    Abstract: A collation device specifies a combination of event conditions in parallel with each other based on a query. The collation device sets the combination of event conditions in a parallel relation to the same window, connects a plurality of windows in series, and generates a similar query that sets a window interval condition between the windows in a connected relation. The collation device compares a similar query with collation data, and detects a combination of events that satisfies a condition of the similar query from among events included in the collation data.

  • Publication number: 20140156692
    Abstract: An extraction program causes a computer to execute a process. The process includes adding an event to a first pattern including the events according to the sequential order, thus generating a second pattern in such a manner that the second pattern is generated by adding the event when a first value is less than a predetermined threshold; when the event is added, adding a predetermined value to the first value, and adding the predetermined value to a second value in a column corresponding to an end of the added event among second values corresponding to respective columns of a table; extracting the second pattern that satisfies a predetermined condition; and when an event in a second or subsequent column in the table is added.

  • Publication number: 20140136149
    Abstract: When a second pattern is to be generated by adding an event to a first pattern including events, an extraction program causes a computer to execute the following process based on combinations of events. That is, the extraction program causes the computer to generate the second pattern when the number of occurrence, in the second pattern, of each of the events included in the combinations is not more than a threshold. The extraction program causes the computer to calculate, based on data including a plurality of events, a frequency at which one or more of the generated second patterns occur in the data. The extraction program causes the computer to extract the second pattern having the frequency satisfying a predetermined condition. The extraction program causes the computer to add a new event to the extracted second pattern.

  • Patent number: 8710773
    Abstract: The driver seat unit and the other-seat unit are connected by the single signal line. A direction of a current passed through a motor is switched using contacts of a window opening switch and a window closing switch in the other-seat unit. When a window closing manipulation is performed by the driver seat unit, the current is passed through a coil of a relay via the contacts of the window closing switch, and a contact of the relay is switched to pass a forward current through the motor. When a window opening manipulation is performed by the driver seat unit, the current is passed through a coil of a relay via the contacts of the window opening switch, and a contact of the relay is switched to pass a reverse current through the motor.

  • Publication number: 20130111503
    Abstract: A collation device generates an NFA by generating an automaton corresponding to an event pattern, replicating an automaton part corresponding to the same series part in which events are connected in the same series in the generated automaton for a plurality of series, substituting each replicated automaton part with a transition that is received in an event of each series, and combining each substituted automaton part through an ? transition. In addition, the collation device collates whether or not the event pattern is included in an event stream by comparing the event stream and the NFA and receiving an event included in the event stream in an NFA part corresponding to a series in which the event occurs out of the replicated NFA parts and operating the NFA part.
