1. A currency handling device comprising a limpness detector, the detector comprising:
- deforming structure having a predetermined shape for deforming a note;
complimentary structure conforming to the deforming structure, wherein the note is passed between the deforming structure and the complimentary structure and the predetermined shape causes the note to be deformed about two transverse axes and at least two axes parallel to a direction of note motion; and
a microphone operably positioned to detect noise produced by deforming the note.

Abstract
A currency handling system has a limpness detector. The limpness detector has a single driven crackle roller with an elongated central bulge and two outer bulges, wherein the central bulge is in conforming relation to a flexible belt. Sheet metal guides further facilitate note deformation and sound production.

11. A currency handling device comprising a limpness detector, the detector comprising:
-
a roller comprising; a central bulge; a first outer bulge extending radially further than the central bulge; and a second outer bulge spaced apart from the first outer bulge extending radially further than the central bulge, wherein the central bulge is positioned axially between the first and second outer bulges; and a belt conforming to the central bulge of the roller, wherein the central bulge has a circumference and the belt conforms to the central bulge over at least about ⅛
the circumference of the central bulge and wherein a note is passed between the belt and the roller to deform the note;a microphone operably positioned to detect sound produced by deforming the note; and first and second guides positioned proximate to the first bulge and the second bulge, respectively, wherein the central bulge is positioned between the guides and the note is passed under the guides and over the outer bulges. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
