Abstract
Abstract A sensor package for ready insertion in properly registered position upon, or for removal from, a cabinet employed in electrical sensing of plane coordinates, is constructed to provide accurate readings when pierced by a small manually operated cursor. A method for manufacturing the package including the affixing of accurately spaced electrodes on the package, is disclosed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
301 words
The method of preparing a sensor package including, providing a rectangular sheet of electrical insulating material, arranging first and second sheets of electrical conductive material in stacked relation to the respective faces of said insulating sheet with the end edges of said first conductive sheet being offset inwardly from the end edges of said insulating sheet and with the side edges of said second conducting sheet being offset inwardly from the side edges of said insulating sheet, arranging first and second rectangular reference sheets of electrical non-conducting material in stacked relation to the respective faces of said conducting sheets with the parallel side edges of said first reference sheet being offset inwardly from the side edges of said first conducting sheet to provide electrode-receiving spaces on said first reference sheet for a first pair of electrodes and with the parallel end edges of said second reference sheet being offset inwardly from the end edges of said second conducting sheet to provide electrode-receiving spaces on said second reference sheet for a second pair of electrode means, effecting a bonding of the several juxtaposed sheets to each other in order to establish a fixed position of the several sheets in the form of an intermediate assembly having the end edges of said second reference sheet normal to the side edges of said first reference Sheet, affixing said electrode means to the intermediate assembly in the respective exposed spaces of the first and second conducting sheets, completing the affixing of said electrode means by filling in any space between said electrode means and the adjacent edges of the corresponding reference sheet with a conducting coating material, and thereafter affixing a protective non-conducting masking strip to the boundary of at least one of said reference sheets in superposed relation to the corresponding completed electrode means.
Claim 2
Independent Claim
301 words
The method of preparing a sensor package including, providing a rectangular sheet of electrical insulating material, arranging first and second sheets of electrical conductive material in stacked relation to the respective faces of said insulating sheet with the end edges of said first conductive sheet being offset inwardly from the end edges of said insulating sheet and with the side edges of said second conducting sheet being offset inwardly from the side edges of said insulating sheet, arranging first and second rectangular reference sheets of electrical non-conducting material in stacked relation to the respective faces of said conducting sheets with the parallel side edges of said first reference sheet being offset inwardly from the side edges of said first conducting sheet to provide electrode-receiving spaces on said first reference sheet for a first pair of electrodes and with the parallel end edges of said second reference sheet being offset inwardly from the end edges of said second conducting sheet to provide electrode-receiving spaces on said second reference sheet for a second pair of electrode means, effecting a bonding of the several juxtaposed sheets to each other in order to establish a fixed position of the several sheets in the form of an intermediate assembly having the end edges of said second reference sheet normal to the side edges of said first reference Sheet, affixing said electrode means to the intermediate assembly in the respective exposed spaces of the first and second conducting sheets, completing the affixing of said electrode means by filling in any space between said electrode means and the adjacent edges of the corresponding reference sheet with a conducting coating material, and thereafter affixing a protective non-conducting masking strip to the boundary of at least one of said reference sheets in superposed relation to the corresponding completed electrode means.
Claim 3
Dependent Claim
56 words
The method of claim 1 including effecting said bonding operation in a first step comprising bonding one of said reference sheets and one of said conducting sheets to said insulating sheet and in a second step comprising bonding the other of said reference sheets and the other of said conducting sheets to the previously bonded sheets.
Claim 4
Dependent Claim
24 words
The method of claim 1 including interposing a layer of dry mounting tissue between adjacent sheets of material prior to effecting said bonding operation.
Claim 5
Dependent Claim
28 words
The method of claim 3 including affixing a rigid backing sheet of electrical non-conducting material to one of said reference sheets following the affixing of said electrode means.
Claim 6
Dependent Claim
54 words
The method of claim 4 including the step of boring apertures extending through each of said four electrode means and thereafter inserting a metallic grommet in each of said apertures thereby to provide for convenient placing of said package in a supporting structure and for convenient attachment of electrical connections to said electrode means.
Claim 7
Dependent Claim
247 words
A package for use in the electrical sensing of plane coordinates including, a rectangular sheet of electrical insulating material, first and second sheets of electrical conducting material in stacked relation to the respective adjacent faces of said insulating sheet, first and second reference sheets of electrical non-conducting material in stacked relation to the respective adjacent faces of said conducting sheets, said first reference sheet having parallel side edges and being of less width than said first conducting sheet and said second reference sheet having parallel end edges and being of less length than said second conducting sheet, a first pair of electrodes attached to said first conducting sheet adjacent the side edges thereof and including a coating of electrical conducting material extending to the adjacent parallel side edges of said first reference sheet, a second pair of electrodes attached to said second conducting sheet adjacent the end edges thereof and including a coating of electrical conducting material extending to the parallel end edges of said second reference sheet, said second and said first pairs of electrodes being out of contact with each other and said side edges of said first reference sheet being normal to said end edges of said second reference sheet, a masking strip of electrical non-conducting material at the boundary of at least one of said reference sheets covering the electrodes of the adjacent conducting sheet, and means bonding adjacent sheets to each other thereby to provide a fixed relation between the respective sheets.
Claim 8
Dependent Claim
247 words
A package for use in the electrical sensing of plane coordinates including, a rectangular sheet of electrical insulating material, first and second sheets of electrical conducting material in stacked relation to the respective adjacent faces of said insulating sheet, first and second reference sheets of electrical non-conducting material in stacked relation to the respective adjacent faces of said conducting sheets, said first reference sheet having parallel side edges and being of less width than said first conducting sheet and said second reference sheet having parallel end edges and being of less length than said second conducting sheet, a first pair of electrodes attached to said first conducting sheet adjacent the side edges thereof and including a coating of electrical conducting material extending to the adjacent parallel side edges of said first reference sheet, a second pair of electrodes attached to said second conducting sheet adjacent the end edges thereof and including a coating of electrical conducting material extending to the parallel end edges of said second reference sheet, said second and said first pairs of electrodes being out of contact with each other and said side edges of said first reference sheet being normal to said end edges of said second reference sheet, a masking strip of electrical non-conducting material at the boundary of at least one of said reference sheets covering the electrodes of the adjacent conducting sheet, and means bonding adjacent sheets to each other thereby to provide a fixed relation between the respective sheets.
