William J Cimino, Robert E Powers Jr: Automatic key identification system. Lahive & Cockfield, February 6, 1990: US04899391 (41 worldwide citation)

A system for identifying and matching key blanks when duplicating an original key. A key holder is provided which positions the key horizontally along its longitudinal axis with the key's flat sides in a vertical plane. A lensing subsystem lights and forms an image of the front profile of the key. A ...
