Abstract
A fingerprint capture device includes a removable, magnetically attached finger aperture selector to facilitate reconfiguration of the device to image a wide range of finger sizes and body regions. The device housing and the selector are also configured for one-handed use, based on the angle and location of the imaging actuator and the selector relative to the device handle. The device includes a camera calibration mount to facilitate adjustments to the camera alignment. Software that is usable with the device can normalize the fingerprint characteristics based on the age and individual characteristics of the subject being imaged.
Claims25
A fingerprint input system, comprising:
- a main housing, comprising:
- an elongate handle comprising a longitudinal axis;
- and
- a rotation hub integrally formed with the elongate handle, the hub comprising:
- an upper convex surface;
- an imaging opening in the upper convex surface;
- and
- a circular flange surrounding the upper convex surface, the circular flange comprising a superior undulating surface;
- a plurality of peripheral hub magnets equally spaced around the circular flange and each of the plurality of hub magnets located a same hub radial distance from a center of the rotation hub;
- an actuator located on a front surface of the elongate handle;
- an imaging assembly inside the elongate handle and comprising an imaging axis;
- a detachable rotary aperture top configured to form rotational interface with the rotation hub, the selector comprising:
- a concave lower surface configured to form a complementary rotational interface with the upper convex surface of the hub;
- a plurality of finger receiving apertures, wherein each aperture is a different size and comprises a chamfered perimeter edge located in an aperture plane;
- and
- a plurality of flanges surrounding the concave lower surface and configured to extend radially outward beyond the circular flange of the rotation hub, wherein the plurality of flanges are radially offset from the plurality of finger receiving apertures, and wherein the plurality of flanges each comprise an undulating surface complementary to a portion of the undulating surface of the circular flange of the rotation hub;
- a plurality of peripheral top magnets equally spaced around the plurality of flanges and each of the plurality of top magnets located a same top radial distance from a center of the top;
- and
- an optically transparent cover between the imaging assembly and the detachable rotary top.
A fingerprint input system, comprising:
- a main housing, comprising:
- an elongate handle comprising a longitudinal axis;
- and
- a rotation hub integrally formed with the elongate handle, the hub comprising:
- a hub interface surface;
- a center;
- an imaging opening in the hub surface;
- and
- a first plurality of alignment structures equally spaced around the rotation hub and each of the plurality of alignment structures are located a same hub radial distance from the center of the rotation hub;
- an actuator located on the elongate handle;
- an imaging assembly inside the elongate handle and comprising an imaging axis;
- a detachable rotary aperture top configured to form rotational interface with the rotation hub, the selector comprising:
- a top interface surface configured to form a complementary rotational interface with the upper convex surface of the hub and comprising a center, wherein the center of the top and the center of the hub define a rotation axis;
- a plurality of finger receiving apertures, wherein each aperture is a different size and comprises a chamfered perimeter edge located in an aperture plane;
- a plurality of flanges surrounding the top interface surface and configured to extend radially outward beyond the rotation hub, wherein the plurality of flanges are radially offset from the plurality of finger receiving apertures;
- and
- a second plurality of alignment structures arranged in a configuration complementary to the first plurality of alignment structures located on the rotation hub.
