Each lifter has a displacement member which can be connected to at least one directable thread and which has two spring arms that can be coupled to lifter blades which move up and down. When the plurality of microcapsules are ruptured, reactants within the plurality of microcapsules react to form a replacement polymer in a break of the insulation material. The algorithm uses simple features, and is intended to be applicable to a wide variety of target-sensor geometries, sensor configurations, and applications. Electric power or switching control of electric power is cross-connected between the ends of the LED tube.
