Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
170 words
A method for manufacturing a card having digital data encoded thereon for reading with electronic data processing equipment which includes an array of sensors, each sensor including a flux generating element and a flux responsive element comprising the steps of forming a first series of apertures spaced from one another in an electrically conductive strip, laminating a support sheet to said apertured electrically conductive strip, forming a second series of apertures spaced from one another in the laminated conductive strip-support sheet assembly, apertures of said second series being connected to apertures of said first series to form discrete portions of said electrically conductive strip spaced from one another, said discrete portions defining an array of electrically conductive loops disposed in a pattern on said support sheet in position corresponding to said sensor array in said processing equipment, interrupting certain of said conductive loops; and encasing said conductive strip-support sheet assembly in opaque material to provide an article for insertion into the card sensing area of said electronic data processing equipment.
Claim 2
Independent Claim
170 words
A method for manufacturing a card having digital data encoded thereon for reading with electronic data processing equipment which includes an array of sensors, each sensor including a flux generating element and a flux responsive element comprising the steps of forming a first series of apertures spaced from one another in an electrically conductive strip, laminating a support sheet to said apertured electrically conductive strip, forming a second series of apertures spaced from one another in the laminated conductive strip-support sheet assembly, apertures of said second series being connected to apertures of said first series to form discrete portions of said electrically conductive strip spaced from one another, said discrete portions defining an array of electrically conductive loops disposed in a pattern on said support sheet in position corresponding to said sensor array in said processing equipment, interrupting certain of said conductive loops; and encasing said conductive strip-support sheet assembly in opaque material to provide an article for insertion into the card sensing area of said electronic data processing equipment.
Claim 3
Dependent Claim
44 words
The method as claimed in claim 1 and further including the step of laminating a second support sheet carrying a plurality of spaced electrically conductive members to said conductive strip-support sheet assembly to position an electrically conductive member over each interruption in said loops.
Claim 4
Dependent Claim
24 words
The method as claimed in claim 1 and further including the step of positioning an X-ray absorbing member over each interruption in said loops.
Claim 5
Dependent Claim
26 words
The method as claimed in claim 1 wherein said first and second series of apertures and the interruptions in said conductive loops are formed by punching.
