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.

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.

Abstract: The ratio of a refresh rate of a display device to a refresh rate of source video is determined. The display device is to display the source video over a repeating number of sub-frames, in sub-frame order. The sequence of frames of the source video is determined for the display device that maintains the ratio. The sequence of frames is delineated so that each frame is represented by the number of sub-frames over which the display device displays the source video. The sequence of frames as delineated by the sub-frames is adjusted to ensure as much as possible that each frame is represented by the same number of sub-frames within the sequence. The source video is displayed on the display device using the sequence of frames as delineated and as adjusted.
