By injecting charge into floating conductors that are operating in this tunneling mode, it is possible to produce additional loading which can be detected by monitoring the power supply current. These changes in supply current may be associated with the visual image of the device at the coordinates at which the change was detected.
By injecting charge into floating conductors that are operating in a tunneling mode, it is possible to generate additional loading that can be identified by monitoring changes in the power supply's current. These changes in current flow may be associated with the visual representation of the device at the specific coordinates where the change occurred.
