US Patent 9101676 Method of operating a volatile material dispenser

A method of operating a volatile material dispenser includes the step of operating the volatile material dispenser according to a pre-defined algorithm for a first operational cycle. The method further includes the steps of sensing a change in an emission parameter initiated by a user and storing information related to the change in emission parameter. Still further, the method includes the step of operating the volatile material dispenser for a second operational cycle according to a new algorithm, wherein the new algorithm comprises the pre-defined algorithm with modifications according to the change initiated by the user.
