Abstract: A fingerprint sensing module includes a sensor substrate having a sensing side and a circuit side, an image sensor including conductive traces on the circuit side of the sensor substrate, and a sensor circuit including at least one integrated circuit mounted on the circuit side of the sensor substrate and electrically connected to the image sensor. The sensor substrate may be a flexible substrate. The module may include a velocity sensor on the sensor substrate or on a separate substrate.

Abstract: An electronic sensor forms a grid to detect surface features of a proximally located object, such as a fingerprint. The grid includes a plurality of parallel drive lines connectable to a drive source and a plurality of parallel pickup lines oriented substantially perpendicular to the drive lines and overlapping the drive lines. The drive lines are separated from the pickup lines by an insulating dielectric layer. The overlaps where the drive lines and pickup lines cross define impedance-sensitive electrode pairs which act as pixels at which surface features of the proximally located object are detected. One or more conductive probes extend from one or more corresponding impedance-sensitive electrode pairs, through an overlay layer of insulating material, to the sensing surface.

Abstract: A finger position sensing apparatus, typically used in a fingerprint sensing system, includes a position pickup plate disposed generally orthogonally with respect to an expected direction of movement of a finger and a plurality of position drive plates having different spacings from the position pickup plate to define plurality of position sensor gaps between respective position drive plates and the position pickup plate. The position drive plates are dimensioned and spaced from the position pickup plate to sense the bulk of a finger rather than fingerprint features.
