measuring a first strength of a first scent of said object with a first electronic sensor, a decay rate constant (α1) of said first scent being known;
measuring simultaneously a second strength of a second scent of said object with a second electronic sensor, a decay rate
constant (α2) of said second scent being known;
calculating a current scent ratio (σ) of said first and second scent strengths;
