Abstract: To efficiently store the large amount of data required for the sewing of large embroidery patterns which are sewn along continuous paths, the path is divided into a plurality of contiguous segments and for each of the segments there is stored the length of the segment and its slope and rate of change of slope at the start of each segment.

Abstract: To fill a container with a predetermined volume of liquid, initially the time required to fill the container with an elemental volume is measured and the filling is continued for a multiple of the measured time, the multiple corresponding to the predetermined volume as a function of the elemental volume. Accordingly, any variations in inlet pressure are adapted to and compensated for.

Abstract: A method of operating a zig zag sewing machine to produce a visible pattern of zig zag stitches in a work fabric along a predetermined path to form a monogram within a defined field on the work fabric is initiated from a common starting location within the field. Initially, the needle bar is unlatched while longitudinal feeding takes place from that starting location so that no stitches are formed. This continues until a point of intersection is reached with the predetermined path. The needle bar is then latched and straight stitches, utilizing lateral needle feeding, are sewn along the predetermined path to a starting point for the monogram. Finally, zig zag stitches are formed along the path, covering the straight stitches and forming the monogram pattern.
