Abstract: Presented is a method for quantifying breastfeeding between a mother and a baby, the method including measuring a physiological volume indicative of stomach fullness volume for the baby; setting a signal threshold value of the physiological volume to correspond to a stomach level that is less than or equal to the stomach fullness volume; obtaining an objective measurement of the physiological volume indicative of a level of fullness of the baby's stomach; and providing an indication to the mother when the objective measurement equals or exceeds the signal threshold value. In one embodiment, for instance, a conductivity sensor may be used to determine the amount of breast milk available in a breast and/or the amount of breast milk that has left the breast during a breastfeeding event.

Abstract: The present invention relates to disposable absorbent articles that include absorbent systems. The absorbent system includes an absorbent pad formed of absorbent materials and having a lateral direction and a longitudinal direction. The absorbent pad has a narrow zone area of increased thickness of absorbent materials that has a length greater than or equal to 80% of the length of the absorbent pad. The narrow zone area has a width in the lateral direction of the absorbent pad that is less than or equal to 62% and greater than or equal to 20% of the width of a non-zone area.

Abstract: Absorbent articles having leg extensions are disclosed. The absorbent articles may include, for instance, an outer cover, a liner, and an absorbent structure positioned in between the liner and the outer cover. The absorbent structure includes a crotch area and leg extensions that extend downwardly from the crotch area and are configured to lay adjacent the thighs of a user. The leg extensions assist in wicking liquids away from the crotch area when the absorbent article is insulted with a liquid. In one embodiment, the leg extensions comprise at least 30% by weight of the absorbent structure or, alternatively comprise at least 30% of the total surface area of the absorbent structure.

Abstract: An additive for improving the solubility of dyes in a dye composition is disclosed. The additive is a zwitterion that has a polarity greater than the polarity of a solvent in which the dye is dispersed or solubilized. In one embodiment, the additive comprises an amino acid or a derivative of an amino acid. Dye compositions formulated according to the present invention are particularly well suited for use in ink-jet printers.
