Abstract:
1. A fingerprint scanning system comprising: an imaging surface capable of receiving a finger; an ultrasound transducer capable of providing information corresponding to a fingerprint of the finger; a probe arm joined to the transducer, the probe arm having a pivot-location; a crank arm pivotally connected to the probe arm; a flywheel pivotally connected to the crank arm; a flywheel driver capable of rotating the flywheel in order to cause the transducer to move along an arcuate path; a linear driver capable of moving the pivot location linearly; a measurer capable of measuring linear positions of the pivot-location and arcuate positions of the transducer; and a coupler capable of coupling one linear position of the pivot-location and one arcuate position of the transducer with information from the transducer.
