  • Patent number: 9495330
    Abstract: A method providing an analytical technique introducing label information into an anomaly detection model. Effective utilization of label information is based on introducing the degree of similarity between samples. Assuming, for example, there is a degree of similarity between normally labeled samples and no similarity between normally labeled and abnormally labeled samples. Also each sensor value is generated by the linear sum of a latent variable and a coefficient vector specific to each sensor. However, the magnitude of observation noise is formulated to vary according to the label information for the sensor values, and set so that normal label?unlabeled?anomalously labeled. A graph Laplacian is created based on the degree of similarity between samples, and determines the optimal linear transformation matrix according to a gradient method. A optimal linear transformation matrix is used to calculate an anomaly score for each sensor in the test samples.

  • Patent number: 9481170
    Abstract: When printing is performed by discharging ink from a printing head onto a lenticular, a carriage motor is controlled such that a carriage is moved in a main scanning direction at a velocity which is slower than a movement velocity of the carriage at the time of performing a normal printing process with respect to a recording medium different from the lenticular as a recording paper and further separated from a home position, and the printing head is controlled such that an ink discharge having a color according to printing data is started with respect to an end portion of the lenticular, and thus the printing of one pass is started. Since the velocity is slower than the movement velocity of the carriage at the time of performing the normal printing process, it is possible to improve printing quality at the time of performing printing with respect to the lenticular.

  • Patent number: 9475280
    Abstract: When a nozzle abnormality detecting mechanism detects an abnormality of the nozzle, in the maintenance process of causing the drive waveform to be applied plural times to the actuator corresponding to the nozzle that the detecting mechanism detects as being abnormal, and thereby causing the ejecting operation to be performed, at least a first-time drive waveform applied to the actuator is a flushing pulse which causes a meniscus in the nozzle not to be positively attracted from an initial position to the pressure chamber, but causes the meniscus to be extruded to the ejection side and thereby causes the liquid to be ejected from the nozzle.
