Patent ID: 8857662

Claim:
A method of operating a dispensing device, comprising the steps of: entering a first active state, detecting a sensory input by a sensor, initiating a first pattern activation sequence configured to energize a drive unit of the dispensing device for a first length of time to actuate a container, entering a second active state upon completion of the first pattern activation sequence, and detecting a second sensory input in the second active state, wherein if the second sensory input is detected before a lapse of time period P, the method comprises the steps of: initiating a second pattern activation sequence configured to energize the drive unit for a third length of time to actuate a container, and wherein if the second sensory input is detected after a lapse of time period P, the method comprises the steps of: initiating the first pattern activation sequence; wherein at least one of the following method steps occurs within the first or the second active state: (i) energizing the drive unit for a second length of time subsequent to the first length of time; or (ii) energizing the drive unit for a fourth length of time subsequent to the third length of time; wherein the first, second, third and fourth lengths of time are not all the same.
