A method and apparatus for gathering system information into a file and transmitting the file to a remote location for presentation as a graphical display. The measurements are preferably performed under conditions approximating the operation of the thin films as electrodes in microswitch array fingerprint sensors. The second acquisition unit is configured to acquire second position information representing a contact position of an object holding the input device on the screen. In some embodiments, a cyclodextrin-based particle is used to deliver siRNA against one or more oncogenes.
