Abstract: A scanner which can read machine-readable code on an object. A scanner has a scanning device, a data device and a reconstruction device. The scanning device can repetively scan the code and provide a scan signal repetively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetively storing it. The reconstruction device is coupled to the data device for reconstructing the code from at least two of the fragments of the code.

Abstract: An electronic sewing machine whose needle bar assembly is made to reciprocate by means of a pair of cooperating solenoids in conjunction with a bobbin driven by a stepping motor to accomplish the sewing. The stepping motor's steps are made variable programmatically by a CPU attached to the machine such that the tightness of a stitch may be controlled. Additionally, the machine may be programmed to deliver a defined number of stitches in a defined number of stitch runs, position the needle up or down, report a variety of accounting and maintenance data and can be taught to perform a variety of sewing runs.
