Abstract
Abstract Improvements in product and production codes and methods for reading same. In one form a bar code is provided wherein one or more of the individual bars of the code are printed or otherwise formed with coded information recorded therein. The bars may be made of printed matter and either divided into code defining segments or voids therein defining readable auxiliary information. In another form, the bars may be printed of magnetic recording material containing magnetic recordings therein of readable auxiliary information. The auxiliary information may be read when the bars are scanned for their coded information or without scanning the bars for the bar code. Reading may be by scanning a path or paths extending normal or oblique to the bars or in a direction parallel to or longitudinally along one or more of the bars to provided substantial additional information, if needed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
108 words
A product marking for use in encoding identification or associated information on an article of manufacture comprising: a) a first scannable code comprising a plurality of alternating light and dark electro-optically scannable marking elements arranged to be scanned sequentially in a first direction by a laser beam and an electro-optical detector of radiation reflected from said elements; and b) a second scannable code defining auxiliary coded information within at least one of said marking elements of said first code with said second code being arranged to be scanned by a transducer in a second direction generally perpendicular to the first direction in which said first code is scanned.
Claim 2
Dependent Claim
108 words
A product marking for use in encoding identification or associated information on an article of manufacture comprising: a) a first scannable code comprising a plurality of alternating light and dark electro-optically scannable marking elements arranged to be scanned sequentially in a first direction by a laser beam and an electro-optical detector of radiation reflected from said elements; and b) a second scannable code defining auxiliary coded information within at least one of said marking elements of said first code with said second code being arranged to be scanned by a transducer in a second direction generally perpendicular to the first direction in which said first code is scanned.
Claim 3
Dependent Claim
28 words
A product marking in accordance with claim 1 wherein said marking elements are elongated bars and spacings therebetween having their longitudinal axes oriented transversely to said first direction.
Claim 4
Dependent Claim
40 words
A product marking in accordance with claim 2 wherein said second code comprises a series of circular voids oriented along the longitudinal axis of at least one of said bars, said circular voids being electro-optically scannable with a laser beam.
Claim 5
Dependent Claim
49 words
A product marking in accordance with claim 2 wherein at least one of said bars is divided into discrete segments of varying widths or spacings so as to define said second scannable code, which second code is optically scannable in a direction along the longitudinal axis of the bar.
Claim 6
Dependent Claim
39 words
A product marking in accordance with claim 2 wherein said bars are formed of magnetic material with a magnetic recording track oriented along the longitudinal axis of at least one of said bars to form said second scannable code.
Claim 7
Dependent Claim
30 words
A product marking in accordance with claim 3 wherein said bars are formed of a material and said circular voids are formed by laser ablation of said bar forming material.
Claim 8
Dependent Claim
15 words
A product marking in accordance with claim 6 wherein said bar forming material is ink.
Claim 9
Dependent Claim
34 words
A product marking in accordance with claim 5 wherein a plurality of magnetic recording tracks are oriented along the longitudinal axis of at least one of said bars to form said second scannable code.
Claim 10
Independent Claim
59 words
A method for scanning coded product marking information comprising: electro-optically scanning in a first scanning direction a first code comprising a series of alternating light and dark marking elements; and scanning a second code contained in at least one of said marking elements, wherein said second code is scanned in a direction generally perpendicular to said first scanning direction.
Claim 11
Independent Claim
59 words
A method for scanning coded product marking information comprising: electro-optically scanning in a first scanning direction a first code comprising a series of alternating light and dark marking elements; and scanning a second code contained in at least one of said marking elements, wherein said second code is scanned in a direction generally perpendicular to said first scanning direction.
Claim 12
Dependent Claim
29 words
A method in accordance with claim 9 wherein said marking elements of said first code are elongated bars having longitudinal axes oriented perpendicular to the said first scanning direction.
Claim 13
Dependent Claim
41 words
A method in accordance with claim 10 wherein said second code comprises a series of circular voids oriented along the longitudinal axis of at least one of said bars, and wherein said circular voids are electro-optically scanned with a laser beam.
Claim 14
Dependent Claim
49 words
A method in accordance with claim 10 wherein at least one of said bars is divided into discrete segments of varying widths or spacings so as to define said second scannable code, and wherein second code is optically scanned in a direction along the longitudinal axis of the bar.
Claim 15
Dependent Claim
51 words
A method in accordance with claim 10 wherein said bars are formed of magnetic material with a magnetic recording track oriented along the longitudinal axis of at least one of said bars to form said second scannable code, and further wherein said second code is magnetically scanned along said longitudinal axis.
