A scaffold plank assembly for engagement to a scaffolding frame. Field oxide area for isolation are first formed in a semiconductor substrate. Also included is a channel selecting part for selectively supplying any one of the data voltage and the common voltage to at least anyone of the dummy output channels. Methods of using the finger orthosis to move a joint between a first and second portion of a finger are also provided. Estimation may comprise inferring the cost of a candidate data partitioning plan, and optimization may comprise generating an optimal partitioning plan based on the estimated costs of computation and inputoutput.
