  • Patent number: 10137712
    Abstract: A recording device includes a recording unit and a medium support unit. The recording unit includes a recording head and a platen that faces the recording head in a first direction. The medium support unit is arranged below the recording unit such that the medium support unit overlaps the recording unit as viewed in the first direction. The medium support unit is configured to move, relative to the recording unit, in a second direction perpendicular to the first direction. The medium support unit has an up-down mechanism configured to move a support position of the recording medium upward in the first direction by being pulled from below the recording unit. The support position commences to move upward in the first direction after the medium support unit commences to move in the second direction relative to the recording unit during pulling of the medium support unit.

  • Patent number: 10133703
    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: 10071549
    Abstract: Systems and methods for printhead position control. The system comprises a controller that identifies a target distance for moving a printhead in a lateral direction to compensate for lateral shifts in a web of print media as the web travels in a continuous-forms printer in a conveyance direction. The controller also identifies a maximum distance for moving the printhead in the lateral direction based on an allowable print error in a color plane of the printer and one or more previous positions of the printhead. The control further moves the printhead for a distance that is a lesser of the maximum distance and the target distance.
