Abstract: Techniques are described for inspection of films in order to detect Machine Direction Line (“MDL”) defects. An example system comprises a light source configured to provide a source of light rays, directed to a film product so that the light rays are incident to a surface of the film product at a non-perpendicular angle of incidence. An image capturing device is configured to generate an image of the film product by capturing a level of light intensity of the light rays exiting the film product in a plurality of image areas, each image area representing a line imaged across the film product that is perpendicular to a direction of manufacture of the film product. An image processing device is configured to process the image of the film product to provide an indication of the detection of one or more machine direction line (MDL) defects in the film product.

Abstract: A capacitive touch sensor includes a touch sensitive viewing area with a border area surrounding the touch sensitive viewing area and having an outermost polygonal perimeter comprising a plurality of sides and vertices. A plurality of spaced apart electrically conductive first electrodes is disposed in the touch sensitive viewing area and extends along a first direction. A plurality of spaced apart electrically conductive second electrodes is disposed in the touch sensitive viewing area and extends along a different second direction. Electrically conductive bus lines are disposed in the border area for electrically coupling the pluralities of the first and second electrodes to a controller. At least one first alignment feature is disposed within the border area near each of at least three vertices of the polygonal perimeter for aligning the touch sensor to a substrate.

Abstract: Method of making a touch sensor including one or more multilayer electrodes and an underlayer disposed on a substrate. The underlayer is disposed between the multilayer electrodes and the substrate. The multilayer electrodes including at least two transparent or semitransparent conductive layers separated by a transparent or semitransparent intervening layer. The intervening layer includes electrically conductive pathways between the first and second conductive layers to help reduce interfacial reflections occurring between particular layers in devices incorporating the conducting film or electrode.
