Abstract: A method includes: obtaining a task definition for a mobile robot, the task definition including (i) a position on an item support carried by the mobile robot, and (ii) an identifier of an item to be placed at the position to form a unit load with the item support; controlling the mobile robot carrying the item support to travel to a pick location for receiving the item from a picker; controlling an output device to render an indication of the position for the picker at the pick location; responsive to placement of the item at the position by the picker, controlling the mobile robot to travel to a handling location.

Abstract: One or more print streams destined for one or more print stream processing modules are optimized prior to printing, based on relevant document attributes. Optimization may balance operation time of a first processing module with that of a second processing module, by appropriate assigning of documents to the print streams. Optimization may separate input print file document pages into sort groups and/or order sort group documents from largest to smallest. Optimization may allocate documents to optimize the inserter throughput without damaging the integrity of the sort groups. With 2-up or 3-up printing or the like, allocation of sort groups between the multiple outputs to be created after printed paper is split may ensure that parallel paper document outputs are as nearly the same length as possible, to minimize paper wastage. Separation of pages of the same document among different streams/modules can be avoided.

Abstract: Multiple print streams destined for individual print stream processing modules are optimized prior to printing. The process of optimizing includes receiving an input representing a plurality of documents to be printed and determining an attribute of each document of the plurality of documents represented by the input. The attribute relates to processing of the respective document through the document processing system. Optimization involves balancing an operation time of a first print stream processing module with an operation time of a second print stream processing module, by assigning each document to one of the print stream processing modules based on its determined attribute.

Abstract: A paper-handling unit serves for generating groups of items, wherein each group includes a plurality of items. The paper-handling unit includes at least one input channel for receiving the items, a portion to generate groups from the received items, a drive-out station for driving out a generated group, a detector detecting predetermined features from the items of a driven-out group, and a controller. The controller is operable to determine whether a predetermined event has occurred to drive the drive-out station to drive out a group if the predetermined event has occurred, to determine whether information was obtained from the detector during a predetermined interval, to stop the paper-handling unit if no information was obtained from the detector during the predetermined interval, and to stop the paper-handling unit if information was obtained from the detector during the predetermined interval which indicates that the driven-out group does not meet at least one predetermined criterion.

Abstract: Two or more dependent print streams destined for individual print stream processing modules are optimized by processing the data for the print streams prior to printing. The process of optimizing includes receiving an input representing a plurality of documents to be printed and determining an attribute of each document of the plurality of documents represented by the input. The attribute relates to processing of the respective document through the document processing system.
