Abstract: An apparatus for electrophoretic control of surfaces is described, including a vehicle component having an outer surface, a substrate, and a coating layer positioned on the substrate, where the coating layer includes electrostatically controlled ink microcapsules, a first pigment having a first color and a negative charge, a second pigment having a second color and a positive charge. The apparatus includes a layer array with a plurality of thin film transistors (TFTs) disposed laterally across the layer array. The apparatus includes a layer array that is positionable to be in proximity to the coating layer. A method for electrophoretic control of surfaces is also described, including placing a layer array in proximity to an outer surface of a component or panel, imparting a first electrical charge from the layer array to change a visual appearance of the outer surface from a first visual appearance to a second visual appearance.

Abstract: Disclosed are a method and a system for extruding, cut into strands, cooling, and chopping a ground food product. The system comprises a cooling unit, a conveyor belt urging the pieces through the unit, and a chopper for cutting the pieces exiting the unit. A cryogen source provides cryogen to the cooling unit. A feeder feeds the ground food product onto the conveyor belt adjacent an inlet of the unit. The feeder also extrudes the ground food product through a nozzle to place the stranded pieces onto the conveyor belt. A shear plate cuts the stranded pieces, while being extruded. A hydraulic system moves the shearing plate. The system is adapted to dispense cryogen to the cooling region at a rate sufficient to lower the temperature of the cut stranded pieces to a desired temperature when they exit the unit. A chopper cuts the extruded and stranded pieces immediately after freezing.
