Abstract
Abstract An item identified by a location code is tracked through a transport image in a process controller (48). The transport image is characterized by input data to the specific construction of tracker units (32, 34). Location codes for each item are received by the process controller 48 and tracked by a service routine (152) to set a divert flag or an inject flag (172). Each location code is advanced through sections of the transport image by an INCH routine (200). When the location code matches a pocket identification a divert gate is actuated to remove an item from the distribution system.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
137 words
A method of tracking an item identified by a location code to one of a plurality of diverter stations in a distribution system, comprising the steps of: injecting items in sequence into the distribution system, each item identified by a location code, generating an injection signal in response to each item injected into the distribution system indicating that a location code is to be tracked, advancing the location code for each item through a series of storage locations representing an image of the distribution system to track the movement of each item, each storage location representing an increment of distance in the distribution system, one or more of the storage locations having an identifying code identifying one of the plurality of diverter stations, and generating a tracking signal to a diverter station associated with a location code.
Claim 2
Independent Claim
137 words
A method of tracking an item identified by a location code to one of a plurality of diverter stations in a distribution system, comprising the steps of: injecting items in sequence into the distribution system, each item identified by a location code, generating an injection signal in response to each item injected into the distribution system indicating that a location code is to be tracked, advancing the location code for each item through a series of storage locations representing an image of the distribution system to track the movement of each item, each storage location representing an increment of distance in the distribution system, one or more of the storage locations having an identifying code identifying one of the plurality of diverter stations, and generating a tracking signal to a diverter station associated with a location code.
Claim 3
Dependent Claim
40 words
The method of tracking an item as set forth in claim 1 including the step of sensing an item location when moving through the distribution system to generate tracking confirmation signals for location codes advancing through the distance related increments.
Claim 4
Dependent Claim
35 words
The method of tracking an article as set forth in claim 1 wherein the step of advancing the location codes includes timing the advancement of such codes to follow the movement of the distribution system.
Claim 5
Dependent Claim
27 words
The method of tracking an article as set forth in claim 3 wherein the location codes are advanced a preset number of increments for each diverter station.
Claim 6
Independent Claim
147 words
A method of tracking a document identified by coded information to one of a plurality of diverter pockets in a distribution system, comprising the steps of: injecting a plurality of documents in sequence into the distribution system, advancing the coded information for each document through a series of storage locations representing an image of the distribution system to track the movement of each document in the distribution system, each storage location representing an increment of distance in the distribution system, one or more of the storage locations having an identifying code identifying one of the plurality of diverter pockets, comparing the coded information for a document with the identifying code of a storage location when that document reaches that storage location, and generating a tracking signal to the diverter pocket associated with the coded information if the coded information matches the identifying code of the storage location.
Claim 7
Independent Claim
147 words
A method of tracking a document identified by coded information to one of a plurality of diverter pockets in a distribution system, comprising the steps of: injecting a plurality of documents in sequence into the distribution system, advancing the coded information for each document through a series of storage locations representing an image of the distribution system to track the movement of each document in the distribution system, each storage location representing an increment of distance in the distribution system, one or more of the storage locations having an identifying code identifying one of the plurality of diverter pockets, comparing the coded information for a document with the identifying code of a storage location when that document reaches that storage location, and generating a tracking signal to the diverter pocket associated with the coded information if the coded information matches the identifying code of the storage location.
Claim 8
Dependent Claim
37 words
The method of tracking a document as set forth in claim 5 including the step of initializing the storage locations with a predictor function to tailor the advancing step to the physical configuration of the distribution system
