Abstract

Abstract The present invention involves a novel form and methods for creating and using such forms. These forms are summaries (hereinafter "document surrogates") of associated objects, such as original documents, processes, or their copies, stored in a document processing system. A document surrogate made in accordance with the principles of the present invention comprises at least one sheet of a information storing substrate material that has a human readable area and a machine readable area. The human readable area may contain at least one area of material which summarizes the associated object. Such a summary may either be made manually by the user or created automatically by the document processing system. The machine readable area comprises a document reference code (32) that is readable and recognizable by the document processing system. The code (32) is located by the system and recognized from an image of the entire page. The reference code (32) encodes an indicator to the storage location of the associated object. Upon encountering a document surrogate, the system may interpret the surrogate to be the equivalent of its associated object and uses the indicator to access the appropriate object. A mechanism may be provided to the system to either enable or disable this equivalence. If disabled, the system would treat the document surrogate like a typical page in a document.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 95 words
A hardcopy medium which can be processed by a document processing system (10) having an input device (16), a processor (12) for executing functions upon electronic files, and a storage area (14) for storing said electronic files, said medium characterised by a substrate sheet bearing marks thereon, said marks including: a code (32) comprising an indicator to an electronic file and a flag, said flag recognizable by said system and causing said system either to substitute said electronic file for said medium or to select said medium instead of said electronic file for further processing.
Claim 2
Dependent Claim 25 words
A hardcopy medium as claimed in claim 1, characterised in that said electronic file is an associated object or process accessible to said system (10).
Claim 3
Dependent Claim 22 words
A hardcopy medium as claimed in claim 1, characterised in that said substrate sheet further includes an area for human readable material.
Claim 4
Dependent Claim 24 words
A hardcopy medium as claimed in claim 3, characterised in that said human readable material contains at least one summary of said electronic file.
Claim 5
Dependent Claim 57 words
A hardcopy medium as claimed in claim 4, characterised in that said summary is user supplied, or is automatically generated, or is partially user supplied and partially automatically generated; and/or is a reduced image of a page of said electronic file (36), and/or is a list of keywords (42), and/or is a list of section headings (52).
Claim 6
Dependent Claim 68 words
A hardcopy medium as claimed in any one of claims 1 to 5, characterised in that said sheet further includes: at least one selection area corresponding to individual electronic files such that a user may select any subset of said individual electronic files; and/or an override selection area such that a user may instruct said system to select said electronic file instead of said medium for further processing.
Claim 7
Dependent Claim 60 words
A hardcopy medium as claimed in any one of claims 1 to 6, characterised in that said system further comprises: a disable mechanism for instructing the system to select said medium instead of said electronic file for further processing, or comprises an enable mechanism for instructing said system to select said electronic file instead of said medium for further processing.
Claim 8
Independent Claim 92 words
A method for processing a hardcopy medium having a machine readable code (32) which comprises an indicator to an electronic file and a flag, said medium being processed by a document processing system having a input device, a processor for executing functions upon electronic files, and a storage area for storing said electronic files, the method including (A) inputting said medium to said system; (B) parsing said machine readable code by said system to read said indicator and said flag; (C) selecting said electronic file instead of said medium for further processing.
Claim 9
Independent Claim 104 words
A method for creating hardcopy medium from electronic files received by a document processing system having an input device, an output device, a processor for executing functions upon said files, and a storage area for storing said files, the said method including (A) receiving an electronic file; (B) storing said file in said system at a address in said storage area; and (C) outputting at least one piece of substrate sheet having a machine readable code, said code comprising an indicator to said electronic file and a flag which instructs said system to select said electronic file instead of said medium for further processing.
Claim 10
Independent Claim 109 words
A method for remotely requesting processing of an electronic file accessible to a document processing system having an input device, an output device, a processor for executing functions upon said files, and a storage area for storing said files, said file being indicated by a hardcopy medium having a code comprising an indicator to said file and a flag, the method including (A) marking a processing cover sheet with desired operations to be performed on said file; (B) inputting said cover sheet and said hardcopy medium into said system; (C) parsing said code to read said indicator and said flag; and (D) processing said file referenced by said indicator.
Claim 11
Dependent Claim 44 words
A method as claimed in claim 10, characterised in that said requested processing includes distribution by facsimile transmission, or distribution by electronic mail, or includes deleting said file, or includes printing said file, or includes copying said file or changing attributes of said file.
Claim 12
Independent Claim 102 words
A method for receiving an updated printout of a process accessible to a document processing system (10) having an input device (16), an output device (18), a processor (12) for executing functions upon electronic files, and a storage area (14) for storing said files, said process being updated by a hardcopy medium having a code comprising an indicator to said process and a flag, the method including (A) inputting said hardcopy medium to said system; (B) parsing said code to read said indicator and said flag; (C) updating results of said process referenced by said direct pointer; and (D) outputting said results.
