A system for performing authentication of a first user to a second user includes the ability for the first user to submit multiple instances of authentication data which are evaluated and then used to generate an overall level of confidence in the claimed identity of the first user. The colorant includes a cyan colorant, a hue-adjusting colorant that absorbs light having a wavelength of from about 500 to about 600 nm, and an optional shade-adjusting colorant that absorbs light having a wavelength of from about 400 to about 500 nm. The reference plate is formed with an opening, the width of which varies throughout the length of the opening, so that the capacitance between the electrodes varies depending on the position of the plate relative to the electrode member. Thereafter, the user’s privileges are determined by the user’s assigned roles. The electronic control module includes control logic for determining a plurality operating parameters of the internal combustion engine based on the monitoring.
