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

Abstract
A dispensing device includes a controller and first and second actuators coupled to the controller and adapted to actuate first and second containers, respectively, to dispense volatile material therefrom. The device further includes a sensor coupled to the controller for detecting an environmental condition. The controller is configured to operate in a first period during which the first and second actuators are inactive, in a second period during which the first actuator is controlled to periodically actuate the first container at a first frequency to dispense volatile material therefrom, and in a third period during which the second actuator is controlled to periodically actuate the second container at a second frequency to dispense volatile material therefrom. If the sensor has detected the environmental condition, the controller is configured to control the first and/or second actuators to periodically actuate the first and/or second containers, respectively, during a fourth period at a third frequency different than the first and second frequencies to dispense volatile material therefrom.

10. A dispensing device, comprising:
-
a controller; first and second actuators coupled to the controller and adapted to actuate first and second containers, respectively, to dispense volatile material therefrom; and a sensor coupled to the controller for detecting an environmental condition, wherein the controller is configured to operate during a first period when the first and second actuators are inactive, during a second period when the first actuator is controlled to periodically actuate the first container for a first actuation sequence to dispense volatile material therefrom, and during a third period when the second actuator is controlled to periodically actuate 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)
