Filed:

Dec 18, 2002

Appl. No.:

10/322912

Inventors:

Michael A. Duncan - Charlotte NC, US
Rodney G. Moon - Charlotte NC, US
Clair F. Rohe - Huntersville NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

B65H007/12

US Classification:

271260, 27126501, 27125801

Abstract:

A system and method for adaptive and predictive analysis of sensor readings to track documents in a document processing system. The system comprises: a plurality of sensors for sensing a document, wherein each sensor includes an associated filtering system for filtering sensor readings, and a performance tracking system for collecting performance data; and a control system that and adjusts filtering characteristics of the filtering system based on the collected performance data. In addition, a correlation system is provided for using data from at least one upstream sensor to interpret an ambiguous downstream sensor signal.

G06F 13/12

US Classification:

710 64, 710 2, 710 3, 710 37, 710 52

Abstract:

A peripheral interface device that is adaptable into a computer system and which provides a communication interface for a plurality of external devices. The peripheral interface device comprises: a plurality of transfer control logic (TCL) modules, wherein each TCL module provides a dedicated interface for an associated one of the external devices, and wherein multiple TCL modules can communicate in parallel with their associated external devices; and a dual port memory (DPM) device that is in communication with an input/output bus of the computer system, wherein the DPM device can selectively communicate with each of the plurality of TCL modules.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

B65H 306

US Classification:

271111

Abstract:

A document processor having closed loop control of the average feeding rate of the documents and closed loop control of the gaps between documents and dynamic control of the removal of documents from the input station. By controlling the rate at which documents are introduced into the system, and the gaps between documents, more documents can be effectively read and processed in a unit of time without exceeding system limitations imposed by hardware (such as closeness of adjacent documents) even as the mechanism changes due to wear or environment.
