Multiple volatile material dispensing device and operating methodologies therefore
First Claim
1. A dispensing device, comprising:
- first and second actuators adapted to actuate first and second containers, respectively, to dispense volatile material therefrom; and
a sensor for detecting an environmental condition,wherein in a first period the first and second actuators are inactive, in a second period the first actuator actuates the first container at a first frequency to dispense volatile material therefrom, and in a third period the second actuator actuates the second container at a second frequency to dispense volatile material therefrom, andwherein, if the sensor has detected the environmental condition, the first and/or second actuators actuate the first and/or second containers, respectively, during a fourth period at a third frequency.

Abstract
A dispensing device includes first and second actuators that actuate first and second containers, respectively, to dispense volatile material therefrom and a sensor for detecting an environmental condition. In a first period the first and second actuators are inactive, in a second period the first actuator actuates the first container at a first frequency to dispense volatile material therefrom, and in a third period the second actuator actuates the second container at a second frequency to dispense volatile material therefrom. If the sensor has detected the environmental condition, the first and/or second actuators actuate the first and/or second containers, respectively, during a fourth period at a third frequency.

10. A dispensing device, comprising:
-
first and second actuators adapted to actuate first and second containers, respectively, to dispense volatile material therefrom; and a sensor for detecting an environmental condition, wherein during a first period the first actuator actuates the first container for a first actuation sequence to dispense volatile material therefrom and during a second period the second actuator actuates the second container for a second actuation sequence to dispense volatile material therefrom, and wherein the first and second actuation sequences are performed only if the sensor has detected the environmental condition. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
