  • Publication number: 20170052058
    Abstract: A digital filter for a digital weigher reduces a calculation time in an adapted filter while maintaining weighing accuracy, a digital weigher includes the filter for the weigher, and a wave filtering process method uses the digital filter for the digital weigher. A fixation section of a FIR filter removes an oscillating component in a predetermined frequency range, from a digital weighing signal. A determination device determines whether an amplitude of an oscillating component contained in a digital weighing signal derived by performing a wave filtering process falls within a predetermined damping range. A control device changes a frequency range of an oscillating component to be removed by an adaptive section of the filter based on a result of the determination. The adaptive section of the filter performs the wave filtering process with respect to the oscillating component in the frequency range changed by the control device.

  • Patent number: 9354961
    Abstract: A computer analyzes the root cause of an event, which has occurred in any of multiple management-target apparatuses, based on one or more rules in a storage device, that denote an association between one or more condition events corresponding to one or more events capable of occurring in any of the multiple management-target apparatuses and a conclusion event, which is the cause in a case where the one or more condition events have occurred. The computer, based on an event occurrence log including contents and an occurrence date and time of an event, determines a first event group, which is multiple events presumed to occur as a result of the same cause, creates a new rule in which the multiple events of the first event group are the condition events and one event of the first event group is the conclusion event, and stores the created new rule.

  • Publication number: 20160004584
    Abstract: An exemplary event analysis method generates a topology, indicating a correlation between management objects corresponding to a correlation between events defined in selected event propagation model, from configuration management information. It generates, from the selected event propagation model and the topology, a causality indicating a correlation between the causal event identifying an identifier of the management object and the type of the event, and the derivative event sequentially taking place from the causal event. It, in generating the causality, identifies the type of the management object where the derivative event takes place and the type of the event, without identifying the identifier of the management object where the derivative event takes place, when the topology for identifying the identifier of the derivative event is ungeneratable. It performs an event analysis by comparing the generated causality and the event actually taking place at the management target apparatuses.
