    摘要: A signal processing method is disclosed, where, after inputting a measurement data weighted-spline filter formula is selected to calculate an initial value of a spline filter, weight is adjusted, spline filter output is calculated, convergence is judged thereafter. When the weight is not judged converged, the weight is updated and the weight adjusting and spline filter output calculation are repeated, to conduct a robust spline filtering on the measurement data.

    摘要: This sensor state determination system is a sensor state monitoring system capable of accurately determining whether or not a detecting sensor used with a railroad vehicle is in an abnormal state. This system includes: a detecting sensor capable of detecting a physical value acting upon the railroad vehicle; and an electronic control device. A monitoring sensor equivalent to the detection sensor is installed at a position equivalent to the position of the detection sensor. The electronic control device is provided with a determination means (coherence calculation section, state determination section) that computes, based on a first signal detected by the detecting sensor and a second signal detected by the monitoring sensor, a coherence value indicating a correlation between the signals. The electronic control device determines that the detecting sensor is in an abnormal state if the coherence value is smaller than a preset abnormality determination value.

    摘要: A form measuring instrument measures a form of a surface of an object to be measured using a contact to follow the surface. A pseudo-measurement point acquirer acquires positional coordinates of the reference point of the contact as pseudo-measurement points when the contact touches the object at a plurality of locations. A normal vector generator estimates a surface or line along the pseudo-measurement points from the pseudo-measurement points to calculate normal vectors extending from the pseudo-measurement points to the surface or line. A contact model locator locates contact models which specify the surface form of the contact so as to coincide the pseudo-measurement points with reference points of the contact models and so as to coincide attitudes of the contact on measurement with attitudes of the contact models. A measurement point calculator calculates cross points as measurement points, at which the normal vectors cross the surfaces of the located contact models.
