    摘要： A system for imaging a distribution of an absorbent material within an absorbent article. The system includes a radiation source and a detector positioned such that the absorbent article is situated between the radiation source and the detector. The absorbent article includes an absorbent material having a spatial distribution within the absorbent article. Infrared radiation within a particular wavelength range (e.g., 3 μm to 3.2 μm) is more likely to be absorbed by the absorbent material than by other materials within the absorbent article. The radiation source is configured to generate infrared radiation incident on the absorbent article. The detector is configured to detect a quantity of the infrared radiation within the particular wavelength range that was transmitted through the absorbent article. The radiation source is further configured to generate data indicative of the spatial distribution of the absorbent material based on the detected quantity of the infrared radiation.

    摘要： The methods herein utilize polarized light for detecting through holes in substrates. A light source directs light through a first polarization filter having a first polarization axis, wherein polarized light travels from the first polarization filter and toward a substrate. The orientation of the polarized light is changed while traveling through substrate material, and is scattered. However, polarized light traveling through a hole in the substrate remains unscattered. A second polarization filter receives unscattered light and scattered light traveling away from the substrate. The second polarization filter includes a second polarization axis angularly offset from and not parallel with the first polarization axis. As such, the second polarization filter blocks the advancement of unscattered light while the scattered light is not blocked by the second polarization filter. The hole is detected based on an absence of unscattered light surrounded by light traveling from the second polarization filter.

    摘要： The present disclosure relates to methods and apparatuses for monitoring substrates advancing along a converting apparatus in a machine direction. The apparatus may include an analyzer connected with a line scan camera through a communication network. The analyzer may be configured as a field programmable gate array, an application specific integrated circuit, or a graphical processing unit. In addition, the line scan camera may include a linear array of pixel data and define a linear field of view, wherein the line scan camera is arranged such that the linear field of view extends in the machine direction. The apparatus may further include an illumination source that illuminates the linear field of view. In operation, the substrate is advanced in the machine direction such that a portion of the substrate advances through the linear field of view. In turn, the apparatus may be configured to perform various monitoring and/or control functions.
