  • Patent number: 10481091
    Abstract: 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.

  • Patent number: 9999552
    Abstract: The present disclosure relates to methods and apparatuses for sensing distortions in patterns of reflected light to create profiles representing surface topographies of absorbent structures during the manufacture of absorbent articles. Inspection systems may include sensors arranged adjacent an advancing absorbent structure on a converting line. In turn, a controller may monitor and affect various operations on the converting line. The inspection systems herein may also include a radiation source that illuminates a surface of an absorbent structure with a predetermined pattern of light extending in the cross direction CD. The sensor senses distortions in patterns of light reflected from the illuminated surface of the absorbent structure and triangulates changes in elevation of the illuminated surface of the absorbent structure relative to the sensor.

  • Publication number: 20170128274
    Abstract: The present disclosure relates to methods and apparatuses for detecting registration features. The apparatuses and methods may utilize sensors in combination with cylindrical optics that blurs the image sampling area in the cross direction, while maintaining focus in the machine direction. The blurring may create an averaging or blending effect of the hue values across the sampled area. The sensors may include red, green, blue (RGB) analog outputs that can characterize sensed registration features by a unique sequence that can be compared with a reference sequence. In turn, the substrate speed and/or tension can be adjusted base on the comparison to control the relative placement of advancing substrates and discrete components in converting lines.

  • Publication number: 20150346813
    Abstract: Disclosed are a system and a method for hands free operating of a head mounted device. An example method includes reading sensor data from sensors associated with a head mounted device worn by a user. The method allows recognizing, based on the sensor data, a gesture generated by a movement of a head of the user. In response to the recognition, an operation associated with the recognized gesture and a mode of the head mounted device of the head mounted device is performed. The gesture can include a rotation, a pitch, and a roll. The operation includes zooming an image on a screen of the head mounted device, panning the image, scrolling a series of images on the screen, and switching modes of the device. A speed of execution of the operation is proportional to a ratio determined from an angle of the head movement.

  • Publication number: 20150290047
    Abstract: The present disclosure relates to methods and apparatuses sensing emitted light caused by fluorescence of adhesive to determine characteristics of absorbent structures during the manufacture of absorbent articles. Some absorbent articles may have absorbent structures that include an absorbent core disposed between a topsheet and a backsheet. And one or more of the absorbent structure components may be assembled with adhesive that fluoresces when excited by ultraviolet light. Aspects of the present methods relate to an inspection system that may be configured to interact with, monitor, and/or control a converting line. The inspection system may include a radiation source that illuminates a surface of an absorbent structure with ultraviolet light. A sensor may be adapted to receive light caused by fluorescence of the adhesive while being irradiated with the ultraviolet light. In turn, the inspection system may determine characteristics of the absorbent structure based on the detected emitted light.
