Abstract: The flight path of drops from an ink jet printer nozzle are corrected to reduce print position error on the print media. Compensation values are stored and retrieved for use by the printer to correct the flight of a drop to the print media. The compensation values are based on the pattern of print data representing the drops in the ink stream with the drop being compensated. To reduce the number of variables that must be dealt with, one or more portions of the print data can be grouped into one or more blocks and each block treated as having a single effect on the drop being compensated. However, basing the compensation value on one predetermined treatment of print drops as having individual effects or as having individual effects in combination with one or more group effects on the drop being compensated does not produce the optimum print appearance for all combinations of print data. Accordingly, one of a plurality of modes (Mode 1, Mode 2, Mode 3) of treating the data in the print data register 70 is selected based upon the pattern of print data representing drops in the ink stream. Depending on the number of drops in the flight path with the drop being compensated, the drops may be treated as each having an individual effect, an individual effect by some drops and a single group effect by the remaining drops or an individual effect by some drops and group effects by multiple groups of the remaining drops. The compensation values are stored in store 75 and more storage space is allotted for compensation values based on the combinations treated as multiple groups because these combinations produce the most visible print error.

Abstract: A digital speed control system for a sewing machine comprises a digital speed setting device (5) which responds to manual depression of a foot pedal by generating a digital position signal. A variable frequency divider (4) divides the frequency of speed related pulses so that its output frequency is an integral submultiple of the input frequency, which is variable as a function of the digital position signal. A period detector (6) senses the interval between pulses that occur successively at the output of the frequency divider and generates a binary data representing the sensed interval. The interval representing data is translated into a second period data in an arithmetic unit (8) according to a predetermined transfer function. A pulse generator (9) translates the second period data into a pulse for activating a magnetic clutch (11 a) or a magnetic brake (11b) depending on a sign of the second period data to accelerate or decelerate the sewing machine (1).
