Abstract: A metal detection device for detecting metal within notes being placed into a note recycler and handling machine includes a note guide having a note passage. The note passage has a first side and a second side. A first printed circuit board (PCB) is disposed within the first side of the note passage of the note guide. The first PCB includes a substrate and a planar metallic coil deposited on the substrate. A second PCB is disposed within the second side of the note passage of the note guide. The second PCB includes a substrate and a planar metallic coil deposited on the substrate.

Abstract: An invention uses three-dimension frame scanning to create a 3D model of the lens openings so that a finished lens cut data file can be created by a noncontact mapping of the frame in which the lens will be installed by a noncontact method combination of articulation and sensor measurements.

Abstract: Described herein is an apparatus and method for characterizing the precise dimensions of a pair of eyeglass frames, including that of the internal setting groove, through a non-mechanical measurement mechanism. The intended spatial resolution in all three orthogonal axes (x, y, & z) is better than 50 microns (millionths of a meter).
