Several systems, methods and integrated circuits capable of reducing blocking artifacts in video data are disclosed. The upper end has a substantially hollow central portion. Various table functions can be integrated in a single table unit since both table elements can be rotated about a pivotal axis by another joint, and can be fixed in a predetermined position. The data feed engine also encodes the built search command as a data feed and publishes a link for the data feed in a data feed catalog. Such compositions and methods show reduced metal corrosion, low toxicity and rapid removal rates of both photoresists and probing inks.
