Claims10
A method comprising:
- a. exposing at least one sensor means to a surrounding environment for detecting and responding to the presence of at least one odor causing agent,
- b. periodically converting the response of each sensor means to a periodic electrical output signal,
- c. sending each periodic electrical output signal to control means wherein a plurality of periodic electrical output signals are used to calculate by linear least squares regression the slope between the periodic electrical output signals,
- d. adding the slopes
- e. activating expulsion of an odor treatment agent into the surrounding environment when the added slopes of all sensor means exceeds a threshold level.
