One embodiment of the present invention provides a system that facilitates representing a shape within a layout of an integrated circuit using a Boolean expression. In one embodiment, an optical frequency domain reflectometry system provides a laser beam to a reference interferometer to produce a reference signal. In a representative example, when the user connects over a Wi-Fi network, he selects \u201cWi-Fi SMS\u201d option from a client. A valve selectively blocks the perforated nipple to permit a hydraulic pressure to be applied to the tubing string uphole of the swab cup, exerting a downhole force on the swab cup to aid in deployment of the artificial lift system. One method includes, during an initial stage of pen life, drawing ink from an ink reservoir through a standpipe, and, during an extended stage of pen life, allowing external air to enter into the standpipe through a standpipe bubbler and drawing ink from within the standpipe but not the ink reservoir.
