Abstract
Abstract A palm print identification system including a scanning probe translatable in contact with a human palm along a scan line. The probe may comprise one or more roller or drag probes, including light illumination and photodector means arranged to generate electrical signals representative of the pattern of palm lines. The spacing of palm lines as thus sensed is compared with a master read from an I.D. card or stored in a computer for I.D. verification.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
95 words
Apparatus for characterizing an individual based upon the spacing of at least two preselected lines on a human palm, comprising scanning probe means translatable with respect to a scan line and in contact with a surface of said palm; said scanning probe means including transducer means for generating output signals representative of the pattern of skin lines along said scan line; and transducer means responsive to the movement of said scanning probe means normal to said scan line for generating output signals representative of the gross surface profile of the palm along said scan line.
Claim 2
Dependent Claim
95 words
Apparatus for characterizing an individual based upon the spacing of at least two preselected lines on a human palm, comprising scanning probe means translatable with respect to a scan line and in contact with a surface of said palm; said scanning probe means including transducer means for generating output signals representative of the pattern of skin lines along said scan line; and transducer means responsive to the movement of said scanning probe means normal to said scan line for generating output signals representative of the gross surface profile of the palm along said scan line.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 wherein said scanning probe means comprises an internal reflection member translatable in contact with said palm along said scan line without rolling.
Claim 4
Dependent Claim
47 words
The apparatus of claim 1 wherein a plurality of scanning probe means are provided, each one individually loaded into contact with said palm and translatable with respect to parallel scan lines for generating a plurality of output signals representative of the skin lines crossing said scan lines.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1 wherein said surface of said palm comprises a line enhancing member for positioning in juxtaposition to said human palm.
Claim 6
Dependent Claim
68 words
Apparatus for characterizing an individual based upon the spacing of at least two preselected lines on a human palm, comprising scanning probe means including at least one internal reflection member having a cylindrical shape and being mounted for rolling along a scan line across the surface of the palm; and transducer means for generating output signals representative of the pattern of palm skin lines crossing said scan line.
Claim 7
Dependent Claim
68 words
Apparatus for characterizing an individual based upon the spacing of at least two preselected lines on a human palm, comprising scanning probe means including at least one internal reflection member having a cylindrical shape and being mounted for rolling along a scan line across the surface of the palm; and transducer means for generating output signals representative of the pattern of palm skin lines crossing said scan line.
Claim 8
Dependent Claim
56 words
The apparatus of claim 5 wherein said scanning probe means is a light pipe, and further comprising light source means for illuminating said light pipe from one end, and said transducer means comprises a plurality of photo detectors focused through said light pipe onto the internal surface of contact of said light pipe with said palm.
Claim 9
Dependent Claim
24 words
The apparatus of claim 5 wherein said surface of the palm comprises a line enhancing member for positioning in juxtaposition to said human palm.
Claim 10
Dependent Claim
100 words
Apparatus for characterizing an individual based upon the spacing of at least two preselected lines on a human palm, comprising scanning probe means translatable with respect to a scan line and in contact with a surface of said palm said scanning probe means including transducer means for generating output signals representative of the pattern of skin lines along said scan line; post registration means; and rotating scan arm means rotatable about said registration means for holding said scanning probe means, and motive means for rotating said scan arm means such that said scanning probe means follows a circular scan line.
Claim 11
Dependent Claim
100 words
Apparatus for characterizing an individual based upon the spacing of at least two preselected lines on a human palm, comprising scanning probe means translatable with respect to a scan line and in contact with a surface of said palm said scanning probe means including transducer means for generating output signals representative of the pattern of skin lines along said scan line; post registration means; and rotating scan arm means rotatable about said registration means for holding said scanning probe means, and motive means for rotating said scan arm means such that said scanning probe means follows a circular scan line.
Claim 12
Dependent Claim
24 words
