Abstract: A system and method for sensing an edge of a region includes at least one distance sensor configured to detect a plurality of distances of objects along a plurality of adjacent scan lines. A controller is in communication with the at least one distance sensor and is configured to determine a location of an edge of a region within the plurality of adjacent scan lines. The controller includes a comparator module configured to compare values corresponding to the detected plurality of distances, and an identification module configured to identify the location of the edge of the region according to the compared values. In one example, the values corresponding to the detected plurality of distances include couplets of standard deviations that are analyzed and selected to identify the location of the edge.

Abstract: A disposable garment comprising a chassis having a front region, a back region, and a crotch region between the front and back regions, the chassis comprising a liquid impervious backsheet and at least one pair of side panels extending laterally outwardly from the chassis. The backsheet comprises a liquid impervious film extending longitudinally in the front, back, and crotch regions, and having a nonuniform lateral width so as to form a first portion in the crotch region and a second portion in the front or back region. The second portion has a lateral width dimension less than the lateral width dimension of the first portion such that the film does not extend into the side panels. At least one of the side panels comprises an elastomeric material extending laterally outwardly from the chassis, wherein the elastomeric material is joined to the second portion of the liquid impervious film.
