    摘要： An encoding system for determining position and position changes of a moving member has a sequence of encoder marks forming incremental patterns and at least one index pattern. Two subsequent incremental patterns are indicative of an incremental position-change of the moving member and the index pattern is indicative of a reference position of the moving member. A sensor arrangement views a section of the encoder-mark sequence, the length of which is greater than one position-change increment. An analyzer is arranged to analyze an encoder-mark pattern in the viewed section with regard to the incremental patterns and the index pattern and to generate, in response to a pattern match found, at least one of an incremental-position-change signal and an index signal.

    摘要： The invention relates to a method of estimating a distance to a surface, whereby an emitter emits light towards a surface, at least some light being reflected by the surface, the surface comprising a detectable feature, the reflected light being received by a first receptor and by a second receptor, the surface being in movement relative to the receptors, the first and the second receptor receiving the light reflected at a first and at a respectively second angle thereby producing a first and a respectively second dataset, each dataset including data representing said feature, the first and the second angle being different, whereby the distance is estimated using the first and the second dataset.

    摘要： By implementation of an optical scanner, the calibration of printheads of a printing mechanism may be performed in a relatively short period of time as compared to known techniques. In one respect, the time required to perform the calibration may be substantially reduced by virtue of the relatively wide field of view of the optical scanner. The relatively wide field of view generally enables for the scanning of test patterns to be performed with a relatively fewer number of scanning passes, thus reducing the time required to perform the scanning operations as well as the calibration operations. In addition, the scanning operations may yield relatively more accurate results as compared to known scanning operations. In one respect, optical scanners are capable of detecting smaller drops of ink on print media by virtue of their higher resolution capabilities. In another respect, all of the printed colors may be accurately detected through implementation of a red, green, blue (RGB) charge coupled device (CCD) contained in the optical scanners.

    摘要： A printing device has a plurality of print stations including dot-forming elements arranged to produce an image on a moving recording medium and provided in a redundant manner, thereby enabling dot-forming-element activity to be distributed between redundant dot-forming elements and errors of dot-forming elements to be compensated. A lateral-position detector arrangement or predictor is arranged to indicate the recording medium's lateral position relative to the print stations during a print process. A controller is arranged to use at least one print mask for each print station to distribute the dot-forming-element activity between the print stations and to compensate the errors of dot-forming elements. The printing device is arranged so that, in response to a detected or predicted change of the relative lateral position, at least one of the currently used print masks is replaced by another one relating to the changed relative lateral position.
