    摘要: A method and apparatus for electrical detection of a finger print has a reduced number of interconnect signals between a sensor area and a substrate and an electronic circuit for excitation and detection of the finger print compared to a single-chip finger print sensor. The individual signals are connected internally at the sensor substrate in such a way that the response from the individual sensor elements can be separated from each other. Cross-talk is reduced by keeping the sensor outputs at a constant potential, thus eliminating the effect of capacitive coupling between different sensor outputs and also between sensor outputs and a ground or reference potential.

    摘要: A system, method, and computer program product for evaluating a conformance of sets of curves using curvature information from curve segments to identify conforming curve segments. These curve segments are evaluated for relative positional variations in a context of a cluster by triangulating corresponding points among the curve segments of the cluster. Little to no deviation between corresponding lengths in the clusters indicate a high probability of match. Confirmation may be done by a more rigorous pattern matcher based upon the conforming curve segments of a cluster.

    摘要: A sensor has drive lines and transverse pickup lines to define an electrode pair where each pickup line crosses a drive line. A reference pickup line is arranged parallel to the pickup lines and a compensation drive line is arranged parallel to the drive lines. A signal source provides a first signal to the drive lines and a second signal that is the inverse of the first signal to the compensation drive line. An amplifier has a first input connected to a pickup line, a second input connected to a reference pickup line, and a output indicative of an object in contact with the electrode pair(s). Each impedance between the compensation drive line and a pickup line, between the reference pickup line and a reference drive line, and between the compensation drive line and the reference pickup line is equal to the impedance at the electrode pair when no object is contact with the electrode pair.
