Abstract: Biometric detection of a fingerprint is provided by a flexible sensor, in which one or more positioning members move at least a portion of the sensor to conform to a shape of a finger disposed along the sensor to enable capture of a rolled-equivalent fingerprint for the finger. Such one or more positioning members move the sensor causing it to curl at least along a region extending between right and left sides of a fingernail of the finger around a front of the finger in order to conform the sensor to the finger so that the sensing elements of the sensor when enabled capture images of the rolled-equivalent fingerprints without rotation or rocking of the finger with respect to the sensor. When sensing elements are optically sensitive, one or more light sources may provide light to illuminate the finger when the sensor captures rolled-equivalent fingerprint images.

Abstract: A system and method for converting fingerprint cards into electronic files is provided having a computer system for inputting biographical information from each of the cards into memory of, or accessible by, the computer, and encoding the biographical information into a barcode which is printed by a printer on a label for affixing to the card. A scanner is operated for scanning each of the cards having the affixed label associated with the card. For each scanned image of a card, the computer system or another computer system decodes the biographical information from the barcode in the scanned image, segments fingerprint images of the fingerprints of different types of fingers at locations in the scanned image, and stores at least the decoded biographical information and the fingerprint images in an electronic fingerprint file for the card and/or a record in a database.

Abstract: The apparatus represents a device having one or two sensors for capturing a single image or two images having the subject's eyes, and processor(s) in a housing with the one or two sensors and/or in a computer system which receives the single image or two images. Such processor(s) determine a head tilt angle between a virtual line extending between the two eyes of the subject in accordance with a predefined features associated with the eyes and a dimension characterizing zero head tilt in the single image or two images, segment left and right iris images, and rotate the segmented left and right iris images in accordance with the angle to substantially remove head tilt when present. The apparatus may also determine head tilt using predefined features associated with a single eye in the image. The resulting iris image(s) are utilized for enrollment or identification.

Abstract: A system and method of capturing an acceptable fingerprint image is disclosed herein. The method includes a step of capturing an initial fingerprint image at a nominal image integration time. Once this initial fingerprint image is captured, a first intermediate fingerprint image at a first intermediate image integration time is captured. Next, an image darkness test is performed followed by an image definition test. If one or more of these tests indicates that the first intermediate fingerprint image is unacceptable, a subsequent intermediate fingerprint image at a subsequent intermediate image integration time is captured. This subsequent intermediate fingerprint image can be captured before the image definition test is performed. Additional intermediate fingerprint images can be captured until an image that has an acceptable darkness level as a well as an acceptable definition level is captured. Also disclosed is a fingerprint scanner that performs this method.

A remote user can use a browser to control the web-enabled live scanner over a network.

Abstract: Light wedges that reflect light internally and produce diffuse light for uniformly illuminating a platen in a print scanner are presented. In one example, a light wedge has a first surface that receives light emitted from an illumination source and a second surface that limits specular reflections. The light wedge transmits light from the illumination source toward the platen, whereby uniform illumination is provided to the platen. In another example, a light wedge has an illumination surface that receives light emitted from the illumination source, a first surface that limits specular reflections, and a second surface that acts as a diffuser. The second surface reflects light out of the light wedge toward the platen, whereby uniform illumination is provided to the platen.

Abstract: A directionally-oriented reflective device is optically coupled to a prism surface in a skin ridge pattern imaging system to reflect illumination light at relatively small angles, along an optical path to an imaging device, so that minimal light is lost from the optical system. Examples of such directionally-oriented reflective devices include, but are not limited to, echelon reflectors, faceted reflective surfaces, retroreflectors, aluminum paint, nacreous pigment, and slightly rough mirror surfaces.

Abstract: A piezoelectric thin film sensor array is used to scan and capture biometric data, for example, a fingerprint image. In one embodiment, a multi-layer structure includes a PVDF layer in between two conductor grids arranged orthogonally to one another. Urethane can be added to one side where a finger is placed. A foam substrate can be used as a support. In one feature, the PVDF, and grids can be peeled off like a label for easy replacement. Multiplexers are switched to scan the sensor. A single pixel or a group of pixels can be detected and output to an image memory. The presence of a fingerprint ridge is detected by virtue of a ring-down oscillation that arises from reflection when an electric field is applied to the piezoelectric thin film sensor array at a pixel in contact with the fingerprint ridge. For example, such a ring-down value associated with a fingerprint ridge can be detected at about 150 ns. (or 5 cycles at 30 MHZ). Other reflections indicative of additional biometrics (e.g.

Abstract: A system and method is provided for generating a preview display of a captured print image from a non-planar platen and for generating a high resolution display of a user-selected area of the preview display. The display processing system comprises a preview generation module and optionally a high resolution display processing module.

The representative pixel values are plotted at the corresponding display window coordinates. The operator can request a high resolution display of an area of the preview display. When a request is received, the captured image data within that area is converted to rectangular system coordinates and displayed.
