The invention provides a canister for reducing emissions of fuel gas. The method comprises the steps of: sensing a stimulus; selecting at least one modification in response to the sensing the stimulus; mapping the selected at least one modification to the first portrait image to generate a second digital still portrait image; and displaying, on the display, the second portrait image. Subscribers are provided with End User Terminals that are characterized by identical phone numbers and service provider details. An image of the exposed test strip and adjacently-located reference color chart may then be captured and processed to identify any color matches between the individual test pads on the test strip and the corresponding sequences of reference color blocks on the reference chart. A PIN diode coupled to an antenna element is biased thereby reflecting the received RF signal out-of-phase within a stub such that the signal is cancelling and stray capacitance of the PIN diode is reduced.
