US Patent:

6687391, Feb 3, 2004

Filed:

Dec 15, 1999

Appl. No.:

09/461344

Inventors:

Walter Guy Scott - North Palm Beach FL
Dean Fedele - Jupiter FL
John F. Carver - Hobe Sound FL

Assignee:

Cross Match Technologies, Inc. - Palm Beach Gardens FL

International Classification:

G06K 900

US Classification:

382126, 382127

Abstract:

A scanning device for electronically capturing a fingerprint image, employing a finger guide unit and a platen. The finger guide unit positions a finger for scanning by means of a gap into which the finger is placed. The guide maintains the finger within the print scanning range when used in conjunction with a movable platen. The guide unit is rotatable allowing the guide to be moved to expose the whole movable platen. The finger guide unit has two guide plates disposed adjacent one another creating a gap. The gap width is adjustable by means of an adjustment device, allowing fingers of any size to be properly positioned and guided within the scanner reading range. The guide plates each have an edge lined with low-friction material which contacts the finger when in use. The guide plates each have an extension which serves as a handle for raising the guide unit and as a hanger for suspending the guide unit above the platen for use. The guide plates also have an alignment rod disposed between them to ensure stabilization and alignment.

US Classification:

219543, 219522, 219201, 382127, 359512, 359831

Abstract:

Devices and methods for applying heat to a platen of a biometric image capturing device are described that remove and prevent the formation of excess moisture on the platen. These devices and methods prevent undesirable interruptions of total internal reflection of a prism that result in biometric images having a halo effect. In embodiments of the invention, an electrically conductive transparent material is used to apply heat to the platen. In other embodiments, resistive heating elements attached to non-optical areas of the platen (e. g. , the ends) are used to apply heat to the platen. Heater assemblies according to the invention can be used to heat an area where a biometric object is placed, or an area adjacent to where the biometric object is placed, to remove and prevent the formation of excess moisture on the platen.

International Classification:

US Classification:

219201, 219522, 219543, 382124, 62 32

Abstract:

Biometric object image capturing systems and methods prevent undesirable interruptions of total internal reflection of a prism that result in improper biometric images. A thermal assembly comprising a plurality of thermal elements is placed adjacent to the image capturing device. The thermal elements upon supply of a current are capable of either heating or cooling the image capturing device or a platen of the image capturing device. If cooling of the biometric object receiving surface is required, the thermal elements can be controlled to decrease temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed. If heating of the biometric object receiving surface is required, the thermal elements can be controlled to increase temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed, to remove and prevent accumulation of moisture.

International Classification:

G06K009/74

US Classification:

356 71, 382124, 382127

Abstract:

Systems and methods for illuminating a platen are provided. A hybrid illumination system uses both diffusion and collimation to efficiently provide a flat, uniform illumination at a platen. One or more diffusers are disposed between the illumination source array and a collimating lens. An illumination system is provided which uses diffused light to illuminate a platen in a print scanner. The illumination system has an illumination source array and a light wedge. The light wedge reflects light internally which makes the illumination even more diffuse. An illumination source array has a plurality of sources that emit blue/green light. In one preferred example, the blue/green light is equal to or approximately equal to 510 nm. Sources are divided into at least a center region and a perimeter region. The density of sources provided in the perimeter region is greater than in the center region to correct for natural light falloff in the illumination system.

Abstract:

A rotating optical system includes an optical element and a measuring device for locating and/or scanning a full palm print and/or full palm and fingerprint for a hand positioned on a non-planar surface of an optical element. The hand is placed on the non-planar surface of the optical element. A measuring device can be rotated about a centerline axis of the optical element. During the rotation, a circular image of the full palm print (including thenar, hypothenar, interdigital, palm heel, “writers palm,” palm pocket, and fingertips) and/or full palm and finger prints, and/or hand characteristic information (e. g. , hand geometry, spacing, etc. ) can be captured by the measuring portion.

Abstract:

A light integrating column having an illumination column and windows that allow light to enter and exit the illumination column. The illumination column can be a solid rod or a hollow tube. In an embodiment, the windows are formed at an angle with respect to each other. Light from a light source enters through one of the windows. The light is internally reflected and diffused inside the illumination column. A diffused uniform light is transmitted out through another window. In an embodiment, a reflective coating is applied to a surface of the illumination column.

International Classification:

G06K 9/74

US Classification:

356 71

Abstract:

A live print scanner includes a transparent tray platen apparatus and a scanning system. The transparent tray platen apparatus includes a base region attached to two rounded side regions. The base region of the tray platen assembly includes a convex portion. A hand is placed atop the base region adjacent to one of the two rounded side regions such that the hand's palm pocket is atop the convex portion. A sensor assembly within the rotary scanning system generates a complete image of a palm print pattern. Because of the side regions and the convex portion, the image generated includes an image of a print pattern on the palm pocket as well as on the side of the palm. A holographic element may be disposed in a light path between an illumination source and the sensor.
