The present invention provides a bi-directional ball seat and method of use. The gas-filled enclosure includes a vent for adding the purge gas to the enclosure and removing the initial gas from the enclosure. The first gate is disposed above a first insulator and the first NMOS transistor having a first transconductance and a first breakdown voltage associated therewith. The method selects one of the color-coded interactable graphical objects as a test object.
