  • Patent number: 9931833
    Abstract: A printing system includes an identification module to identify a number of the encoder pulses generated by an encoder at a rate corresponding to a speed of a media during a time interval. The printing system also includes an alignment module to at least one of change the number of encoder pulses or scale the encoder pulses generated by the encoder based on an amount of variation between the number of encoder pulses detected and the number of encoder pulses to maintain the number of encoder pulses constant.

  • Patent number: 9587710
    Abstract: An adjustable drive mechanism, which may be used to control the elevation angle of a telescope or antenna, is disclosed. The adjustable drive mechanism can include a base plate configured to couple with a support structure and having a first spherical portion facing away from the support structure. In addition, the adjustable drive mechanism can include a gear box having a pinion gear to interface with a driven gear of a telescope or antenna, and a housing in support of the pinion gear and including a second spherical portion configured to interface with the first spherical portion of the base plate. The first spherical portion and the second spherical portion can be movable relative to one another in three rotational degrees of freedom to facilitate alignment and positioning of the pinion gear relative to the driven gear.

  • Patent number: 9539829
    Abstract: According to an example, printing on a media web may include outputting a first instruction to print a first frame on the media web. A first encoder count of an encoder may be determined between a first alignment mark and an end of frame for the first frame. Additionally, a second encoder count of the encoder may be determined between the first alignment mark for the first frame and a second alignment mark for a second frame. A difference value may then be calculated between the first encoder count and the second encoder count. Based on the difference value, a scaling factor of the encoder may be determined. Accordingly, another instruction may be output to print another frame on the media web based on the scaling factor.
