Method and systems for nerve repair and for microfabrication. The design is partitioned into first and second clusters. The support post height of the columnar spacers is thus measured in advance to control the quantity of dispensed liquid crystals based on the measured value. Various embodiments are applicable to a variety of communication applications including OFDM or CDMA communication systems. The TIM bitmap may identify each station via a bit on a page in the bitmap based upon an assignment of the station to a position in the TIM bitmap. The method further includes comparing the tag structure signature against a set of known bad tag structure signatures to determine similarity.
