Abstract: A printshop contains resources that are utilized to complete print jobs. The resources are partitioned into autonomous cells. Each autonomous cell is capable of completing at least one class of print job. Print jobs are assigned to the autonomous cells for completion. An autonomous cell may subdivide a print job into smaller sized lots and process the smaller size lots in parallel. This approach enhances the efficiency of the shop, decreases the work in progress, labor and inventory costs associated with running the print jobs and increases the utilization of the printing equipment in the printshop.

Abstract: A battery powered, hand held, light weight electrical shocking device provides a visible and audible display of sparks continuously upon the operation of a switch. The device is capable of delivering a jolting shock. The display of sparks makes clear the nature of the device and serves as a deterrent to unruly persons. The circuit comprises a free-running multi-vibrator, a small transformer, a rectifier, a voltage doubler and an internal spark gap. The circuit can deliver a series of short duration, high voltage low current electrical shocks from two penlight batteries.
