摘要:
A method for coloring a disposable absorbent article comprising the steps of providing a plurality of elements each comprising at least one imparted color; wherein the imparted color was provided by a coloration technique, and joining at least two elements that were subjected to different coloration techniques to yield the disposable absorbent article; wherein the imparted colors of the elements subjected to the different coloration techniques are contained within a CIELab color space volume of less than about 190. The imparted colors of the elements subjected to the different coloration techniques may also be contained within a CIELab color space hue difference of less than about 4. The imparted colors of the elements subjected to the different coloration techniques may also be contained within a CIELab color space total color difference of less than about 10.
摘要:
A disposable absorbent article comprising a front waist region, a rear waist region, and a crotch region, wherein said absorbent article further comprises at least three discrete elements each comprising at least one visible surface; wherein at least three or more of the visible surfaces comprise an imparted color wherein said colors are color matched. Color matching exists when said colors are contained within a specified CIELab color space volume, have a specified hue difference, or total color difference.

Systems and methods for multi-channel detection of an instability in a furnace comprising a plurality of detectors are disclosed. Each of a plurality of detectors provides a first measurement related to the plurality of burners when the furnace is operating in a stable condition. A stable signal component representation is determined based on the first measurement from each of the plurality of detectors. Each of a plurality of detectors provides a second measurement related to the plurality of burners when the furnace is operating in an unknown state. An unstable signal component representation is determined based on the stable signal component representation and a second measurement from each of the plurality of detectors. An instability is detected based on the unstable signal component representation and an instability threshold.
