Patent number: 7724927Abstract: Methods and systems according to the invention may compare a large-area biometric specimen and a small-area biometric sample. For example, a large-area plain surface fingerprint image may be stored in a fingerprint database as a specimen, and then a small-area plain surface fingerprint image may be acquired as a sample. The small-area image sample may be submitted to a fingerprint matching system for comparison with a large-area image specimen from the database. A determination may be made as to whether the small-area image matches a portion of the large-area image.Type: GrantFiled: June 14, 2006Date of Patent: May 25, 2010Assignee: Ultra-Scan CorporationInventors: John K. Schneider, Fred W. Kiefer

Patent number: 7440929Abstract: The invention includes methods, systems and devices for authenticating transactions. A method may begin by enrolling at least two biometric specimens to a database. A false acceptance ratio (“FAR”) is determined for each of the specimens, and authorization options are identified. A cost value is calculated for at least one of the options to provide a calculated cost value (“CCV”). The CCV may be a function of the FAR(s) of the specimen(s) corresponding to the option. An acceptable cost value range (“ACV range”) may be identified, and compared to the CCV. If it is determined that the CCV is in the ACV range, then the option is selected. If the CCV is in the ACV range, then a set of biometric samples is provided (the “sample set”). The sample set is compared to the biometric specimens, and it is determined whether the biometric samples match the biometric specimens. If the biometric samples match the biometric specimens, then the transaction is authorized.Type: GrantFiled: May 26, 2006Date of Patent: October 21, 2008Assignee: Ultra-Scan CorporationInventors: John K.

Patent number: 7400751Abstract: A finger imaging system having a linear actuator, a pivot arm mounted to the linear actuator and an energy transducer mounted to the pivot arm is disclosed. The system may include an arcuate platen positioned to receive energy from the transducer. A finger may be placed on the platen, and the position of the transducer may be fixed at a first position relative to the length of the finger. The pivot arm may be moved in order to move the transducer along an arcuate path while maintaining the transducer at the first position relative to the length. As the transducer moves along the arcuate path, energy may be emitted from the transducer and reflected from the finger. The reflected energy may be detected and data corresponding to the amount of time between sending and receiving energy may be stored as data along with the linear and angular position of the transducer.Type: GrantFiled: November 5, 2004Date of Patent: July 15, 2008Assignee: Ultra-Scan CorporationInventors: John K.

Patent number: 7145129Abstract: An unsealed optical encoder does not function properly in a fluid other than air because the optics do not function when interfaced with a medium having an index of refraction significantly higher than air. The collimating lens of an optical encoder has two refracting surfaces, at least one of the refracting surfaces being convex. An orthogonal cap of the present invention is attached over an optical encoder's collimating lens to create a sealed air cavity between the convex refracting surface of the collimating lens and the orthogonal cap. This placement of the orthogonal cap is such that the collimated light leaving the sealed air cavity may enter the surrounding medium at an angle that is normal to the surface of the medium, such as transparent oil, so that the collimated light does not bend even though the light is traveling from air to a much slower medium.Type: GrantFiled: May 27, 2005Date of Patent: December 5, 2006Assignee: Ultra-Scan CorporationInventors: John K Schneider, Stephen M Gojevic, Jack C Kitchens
