Publication number: 20130272585Abstract: Methods and sensors are disclosed for executing a biometric function. Illumination light is generated and directed to a deformable layer when the deformable layer is in a state of deformation resulting from pressure applied to the deformable layer by a skin site. Light scattered from the deformable layer is received. A fingerprint pattern of the skin site is determined from the received light. The biometric function is performed with the determined fingerprint pattern.Type: ApplicationFiled: October 2, 2012Publication date: October 17, 2013Applicant: LUMIDIGM, INC.Inventor: Lumidigm, Inc.

Publication number: 20130027685Abstract: Methods and apparatuses for performing biometric determinations using optical spectroscopy of tissue. The biometric determinations that are disclosed include determination or verifications of identity, estimation of age, estimation of sex, determination of sample liveness and sample authenticity. The apparatuses disclosed are based upon discrete light sources such as light emitting diodes, laser diodes, vertical cavity surface emitting lasers, and broadband sources with multiple narrow-band optical filters. The multiple light sources are encoded in a manner that the tissue response for each source can be efficiently measured. The light sources are spaced at multiple distances from a detector to contribute differing information to the biometric determination task as do light sources with different wavelength characteristics.Type: ApplicationFiled: September 25, 2012Publication date: January 31, 2013Applicant: LUMIDIGM, INC.Inventor: LUMIDIGM, INC.

Patent number: 8355545Abstract: A biometric feature detection system is provided according to one embodiment. The system may include a target, an illumination source, a color filter array, a light detector, and a computational unit. The illumination source illuminates a portion of the target with monochromatic light at a large angle of incidence measured from the normal of the target surface. The light detector may be configured to receive light from the target through the color-filter array and provide an image of the target surface. Each pixel of the light detector may correspond to one of a plurality of color filter mosaics such that each pixel detects light associated with a corresponding color filter. The computational unit may be interfaced with at least the light detector. The computational unit may include instructions to monitor the levels of monochromatic light and make proximity, presence and segmentation determinations based on the detected levels of monochromatic light.Type: GrantFiled: April 10, 2008Date of Patent: January 15, 2013Assignee: Lumidigm, Inc.Inventors: Stephen P.

Publication number: 20120257046Abstract: Methods and devices of studying a predefined portion of an object having a feature of interest are disclosed. The feature of interest defines a class of objects that includes the object. Light sources directly illuminate the object from different illumination directions. The light sources are maintained in a stable configuration relative to the object. For each illumination direction, an image is generated from light scattered from the object with a camera maintained in a stable configuration relative to the light sources. A methodology derived from machine learning for the class of objects is applied to filter the generated images are filtered for a characteristic consistent with the fetaure of interest. Surface gradients are determined from the filtered images and integrated to generate a topography of a surface of the object.Type: ApplicationFiled: April 10, 2012Publication date: October 11, 2012Applicant: LUMIDIGM, INC.Inventors: Horst Arnold Mueller, Ryan Eric Martin, Robert K.
