Abstract

Abstract A fax message transmitted by a facsimile transmitter includes bar coded headers in its first page. At least one of these headers contains the name of an addressee that is also a user on a network. A fax server receiving the incoming fax message inspects the first page of the incoming facsimile to locate the bar coded headers. If a TO: header is found it is used to determine the corresponding E-mail address, and the fax is automatically routed as E-mail on the network to the addressee. Any other headers, such as a FROM: or SUBJECT: header have their bar coded content converted to ASCII and attached as ASII strings to the first page for easy inspection. An asymmetrical nature of the bar code used allows the fax server to determine which of a left-to-right or right-to-left scanning direction produces valid bar code. This in turn indicates whether the headers for the first page are right side up or upside down. By implication, this determines the orientation for the entire fax document. If the document is found to be upside down the fax server erects the document before mailing it to the addressee. The fax server or some other application running on a computer served by the network may be the addressee, and if the incoming fax is a request for information (whether by further bar code or check marks in predefined fields) the information may simply be sent by return fax to the sender, perhaps as part of the same phone call.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 126 words
A method of routing the digitally encoded facsimile representation of a document to a destination on a network, the method comprising the steps of: scanning in opposing directions a selected page of the document for bar code; detecting the presence of a selected bar code cipher in a selected location within the scanned bar code, the selected cipher being asymmetrical when scanned from opposing directions; converting a remaining portion of the scanned bar code into an address suitable for use in addressing a destination location on the network; erecting the pages of a document that is upside down in response to the detecting step being successful upon a bar code scanned in a selected direction; and sending the document to the destination location on the network.
Claim 2
Independent Claim 126 words
A method of routing the digitally encoded facsimile representation of a document to a destination on a network, the method comprising the steps of: scanning in opposing directions a selected page of the document for bar code; detecting the presence of a selected bar code cipher in a selected location within the scanned bar code, the selected cipher being asymmetrical when scanned from opposing directions; converting a remaining portion of the scanned bar code into an address suitable for use in addressing a destination location on the network; erecting the pages of a document that is upside down in response to the detecting step being successful upon a bar code scanned in a selected direction; and sending the document to the destination location on the network.
Claim 3
Independent Claim 142 words
A method of addressing a document to be transmitted to an addressable destination on a network, the method comprising the steps of: expressing the address of a destination on a network as a visual bar coded image upon a page of a document to be transmitted by facsimile; encoding the document according to a format for the digital transmission by facsimile; sending the encoded document to a fax server connected to a network upon which the destination address is located; scanning a selected page of the document for bar code; detecting the presence of a selected bar code cipher in a selected location within the scanned bar code; converting a remaining portion of the scanned bar code into an address suitable for use in addressing a destination location on the network; and sending the document to the destination location on the network.
Claim 4
Independent Claim 142 words
A method of addressing a document to be transmitted to an addressable destination on a network, the method comprising the steps of: expressing the address of a destination on a network as a visual bar coded image upon a page of a document to be transmitted by facsimile; encoding the document according to a format for the digital transmission by facsimile; sending the encoded document to a fax server connected to a network upon which the destination address is located; scanning a selected page of the document for bar code; detecting the presence of a selected bar code cipher in a selected location within the scanned bar code; converting a remaining portion of the scanned bar code into an address suitable for use in addressing a destination location on the network; and sending the document to the destination location on the network.
Claim 5
Dependent Claim 59 words
A method as in claim 2 wherein the selected cipher is asymmetrical when scanned from opposing directions, wherein the scanning step is performed in opposing directions, and further comprising the step of erecting the pages of a document that is upside down in response to the detecting step being successful upon a bar code scanned in a selected direction.
Claim 6
Independent Claim 72 words
A method comprising the steps of: storing a digital representation of a document within a computer system at a destination; transmitting from a sending entity a bar coded request by facsimile to the computer system at the destination; reading the bar code to determine an action to perform in response to the transmitting of the bar coded request; and sending by facsimile the digital representation of the document to the sending entity.
Claim 7
Independent Claim 72 words
A method comprising the steps of: storing a digital representation of a document within a computer system at a destination; transmitting from a sending entity a bar coded request by facsimile to the computer system at the destination; reading the bar code to determine an action to perform in response to the transmitting of the bar coded request; and sending by facsimile the digital representation of the document to the sending entity.
Claim 8
Dependent Claim 34 words
A method as in claim 4 wherein the transmitting step includes a bar coded return address, and the sending step uses the bar coded return address in sending the digital representation of the document.
Claim 9
Independent Claim 106 words
A method comprising the steps of: storing digital representations of a plurality of documents within a computer system at a destination; transmitting by facsimile from a sending entity a form including a bar coded request for the return transmission of information, indicia corresponding to at least one of the documents in the plurality thereof, and a bar coded return address accessible by facsimile; reading the bar code request for the return transmission of information; determining from the indicia at least one digital representation to be sent to the return address; and sending by facsimile to the return address each digital representation determined in the determining step.
Claim 10
Independent Claim 106 words
A method comprising the steps of: storing digital representations of a plurality of documents within a computer system at a destination; transmitting by facsimile from a sending entity a form including a bar coded request for the return transmission of information, indicia corresponding to at least one of the documents in the plurality thereof, and a bar coded return address accessible by facsimile; reading the bar code request for the return transmission of information; determining from the indicia at least one digital representation to be sent to the return address; and sending by facsimile to the return address each digital representation determined in the determining step.
Claim 11
Dependent Claim 28 words
