SENSOR ORIENTATION, CIRCUIT-BOARD CONSTRUCTION, REMOTE DEVICES, AND INTERACTIVE ENROLLMENT IN SKIN-PATTERN PRINT ACQUISITION

摘要

Our invention is a device for acquiring fingerprint data using a capacitive sensor in an orientation which maximizes the amount of interesting fingerpri nt data gathered to increase the reliability of any fingerprint verification system. It also includes several indicia which facilitate proper alignment o f the fingerprint on the sensor. The sensor can include additional circuitry t o perform the verification itself. Our invention also includes apparatus for configuring the electronic circuitry and sensor in a highly compact conformation which increases the applicaitons of the verificaiton system. Su ch additional applicaitons include placing the verificaiton system in a remote device, or mounted in a weapon. The configuring apparatus includes plural circuit boards and an interconnection, which is both electrical and flexible , between the plural circuit boards. Further the plural circuit boards and the interconnections are made from a unitary part. Our invention further include s a method for configuring plural electronic elements which are used to acquir e and process fingerprints. Interactive enrollment procedures are enabled by a pair of bar graph display for viewing by the enrollee to optimuze template contrast and information content, and train the enrollee.
