Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
Data input pen for an electronic signature verification system including at least one piezoelectric member (24, 26) mounted in cantilever fashion and extending longitudinally of the pen from a mounted end (23, 27) to a movable end (25, 28) and having electrode means (34, 36, 38, 40, 42; 52, 54) thereon for producing a signal responsive to relative movement between said mounted and movable ends arising during pen use.
Claim 2
Dependent Claim
69 words
Data input pen for an electronic signature verification system including at least one piezoelectric member (24, 26) mounted in cantilever fashion and extending longitudinally of the pen from a mounted end (23, 27) to a movable end (25, 28) and having electrode means (34, 36, 38, 40, 42; 52, 54) thereon for producing a signal responsive to relative movement between said mounted and movable ends arising during pen use.
Claim 3
Dependent Claim
23 words
Data input pen as claimed in claim 1 in which said member has a hollow tubular form which is coaxial with the pen.
Claim 4
Dependent Claim
20 words
Data input pen as claimed in any preceding claim in which the electrode means are symmetrical about the pen axis.
Claim 5
Dependent Claim
22 words
Data input pen as claimed in any preceding claim in which the electrode means extend for substantially the length of the member.
Claim 6
Dependent Claim
38 words
Data input pen as claimed in any preceding claim in which a said piezoelectric member (24) for producing transverse acceleration signals is arranged rearwardly in the pen of a said piezoelectric member (26) for producing axial pressure signals.
Claim 7
Dependent Claim
47 words
Data input pen as claimed in claim 5 in which said piezoelectric member (24) for producing transverse acceleration signals has said electrode means in the form of a common electrode on one surface of the member, and four spaced electrodes on the other surface of the member.
Claim 8
Dependent Claim
38 words
Data input pen as claimed in claim 5 or 6 in which said piezoelectric member (26) for producing axial pressure signals has said electrode means in the form of an inner tubular electrode and an outer tubular electrode.
Claim 9
Dependent Claim
28 words
Data input pen as claimed in claim 5 in which said piezoelectric member (26) for producing axial pressure signals carries a forward writing tip (21) of the pen.
Claim 10
Dependent Claim
25 words
Data input pen as claimed in any preceding claim including electronic circuitry (22) disposed in the pen, and leading to a pen output cable (18).
