    Abstract: A method of coating a substrate with a particulate coating composition is disclosed that creates a coated substrate having a controlled, nonuniform surface property profile that varies along at least one primary dimension. The substrate is positioned on a textured template. An effective amount of the particulate coating composition is buffed onto a surface of the substrate with the at least one orbital applicator moving in a plane parallel to surface in a plurality of directions relative to a point on the surface in an orbital manner while at least one process variable is changed during the coating of the substrate. Process variable that can be varied during coating include application time, application pressure, coating temperature, the contour of the textured template, orbital speed, web speed, and the particulate coating composition.

    Abstract: A device includes a connected array of cells formed in a stack of flexible sheets. Each pair of adjacent sheets in the stack includes a first sheet and a second sheet bonded together at multiple bond locations. Each sheet has an electrically conductive layer disposed on an electrically non-conductive layer, the conductive layer comprising an electrically conductive non-metal material. Each pair of adjacent sheets in the stack is arranged so that the non-conductive layer of each first sheet is between the conductive layers of the first and second sheets. The cells of the array reversibly transition between an open state and a closed state in response to an electric potential having a magnitude greater than a threshold value applied between the conductive layers of the first and second sheets.
