    Abstract: According to one embodiment, a solar device, comprises one or more photovoltaic cells disposed in an encapsulant and a light control structure including a louver film having a series of louver structures, wherein each louver structure includes one or more groupings of a plurality magnetizable particles aligned at least in a first orientation dispersed in a binding matrix. The light control structure substantially transmits light incident at a first angle and substantially limits transmission of light incident at a second angle. Each louver structure is spaced apart from an adjacent louver structure, wherein each louver structure is substantially aligned in a plane substantially parallel to an adjacent louver structure.

    Abstract: A method of applying magnetizable particles onto an adherent web includes several steps. Step a) provides a magnetizable particle coating apparatus comprising a downward sloping dispensing surface at least partially disposed within an applied magnetic field. Step b) disposes an adherent web between upper and lower magnetic members and beneath the downward sloping dispensing surface, wherein the web comprises a backing having a curable binder precursor layer disposed on a major surface thereof. Step c) disposes magnetizable particles onto at least a portion of the downward sloping dispensing surface within the applied magnetic field, and subsequently disposed onto the curable binder precursor layer while the adherent web is advanced from an upweb position to a downweb position. Step d) at least partially cures the curable binder precursor layer to fix the orientations of the magnetizable particles.

    Abstract: A method may include coupling a first electrical connector of an article to a second electrical connector of a measurement device. The article may include a tested material, the first electrical connector, and a plurality of electrical contacts electrically connected to the first electrical connector. The measurement device may include a power source and a user interface. The method also may include causing, by a controller, an electrical signal to be applied to a pair of drive electrical contacts from the plurality of electrical contacts. The method further may include receiving, by the controller, from an analog-to-digital converter, a measured voltage measured using a measurement electrical contact from the plurality of electrical contacts. The method also may include determining, by the controller, whether the tested material includes a crack or other defect based on the measured voltage.
