A method is provided for accurately sampling pixels in a fixed-format display, which is connected to a host computer through an analog video display adapter. When a user selects objects, the dispersion between the objects is found with respect to each of a plurality of feature quantities. Interconnections between the first connection elements and the second connection elements connect first connection elements that are electrically offset from the second connection elements of the stackable non-shared signal connector. The fastener assembly is coated with the polymer composition by vacuum coating a dispersion of the polymer composition in a solvent such as water and removing the solvent. The frequency source may be a conventional GSM frequency synthesizer having a settling time in the range of about 500 microseconds to about 600 microseconds.
