Abstract

A dispensing device includes an actuating device that actuates first and second containers, respectively, and a sensor for detecting an environmental condition. In a first period the actuating device is inactive, in a second period the actuating device actuates the first container at a first frequency, and in a third period the actuating device actuates the second container at a second frequency. If the sensor has detected the environmental condition, the actuating device actuates the first and/or second containers, respectively, during a fourth period at a third frequency.

Claims

1. A dispensing device, comprising:

an actuating device adapted to actuate first and second containers, respectively; and

a sensor for detecting an environmental condition,

wherein in a first period the actuating device is inactive, in a second period the actuating device actuates the first container at a first frequency, and in a third period the actuating device actuates the second container at a second frequency, and

wherein, if the sensor has detected the environmental condition, the actuating device actuates the first and/or second containers, respectively, during a fourth period at a third frequency.

2. The dispensing device of claim 1, wherein the first and second containers are aerosol containers.

3. The dispensing device of claim 1, wherein the third frequency is greater than the first and second frequencies.

4. The dispensing device of claim 1, wherein during the fourth period the actuating device actuates the first container if the dispensing device had been operating in the second period and the actuating device actuates the second container if the dispensing device had been operating in the third period.

5. The dispensing device of claim 1, wherein the sensor is a motion sensor.

6. The dispensing device of claim 1, further comprising an input device coupled to a controller to allow a user to modify the first, second, and third periods and the first, second, and third frequencies.

7. The dispensing device of claim 1, wherein, by default, the first period is set between 12:

00 AM and 6;

00 AM, the second period is set between 6;

01 AM and 3;

00 PM, the third period is set between 3;

01 PM and 11;

59 PM, the first and second frequencies include one actuation every forty minutes, and the third frequency includes one actuation every twenty minutes for a total of six actuations.

8. The dispensing device of claim 1, wherein the sensor is deactivated during the fourth period.

9. The dispensing device of claim 1, wherein the first, second, and third periods are consecutive time periods within a twenty-four hour period.

10. A dispensing device, comprising:

an actuating device adapted to actuate first and second containers, respectively; and

a sensor for detecting an environmental condition,

wherein during a first period the actuating device actuates the first container for a first actuation sequence and during a second period the actuating device actuates the second container for a second actuation sequence, and

wherein the first and second actuation sequences are performed only if the sensor has detected the environmental condition.

11. The dispensing device of claim 10, wherein during a third period the actuating device is inactive.

12. The dispensing device of claim 11, wherein the first and second actuation sequences last for a fourth period.

13. The dispensing device of claim 12, wherein the fourth period is two hours and the first and second actuation sequences include one actuation every twenty minutes for two hours.

14. The dispensing device of claim 11, wherein the sensor is deactivated during the third period and the first and second actuation sequences.

15. The dispensing device of claim 10, wherein the first and second actuation sequences are interrupted if the first or second periods, respectively, elapse.

16. The dispensing device of claim 10, wherein the first and second containers are aerosol containers.

17. The dispensing device of claim 10, wherein the sensor is a motion sensor.

18. The dispensing device of claim 11, wherein the first, second, and third periods are consecutive time periods within a twenty-four hour period.

19. A dispensing device, comprising:

a sensor for detecting a condition; and

an actuating device adapted to actuate first and second containers, respectively,

wherein the actuating device actuates the first and second containers, respectively, during a twenty-four hour period that is divided into consecutive first, second, and third periods,

wherein during the first period the actuating device is inactive, during the second period the actuating device actuates the first container, and during the third period the actuating device actuates the second container; and

further wherein if the sensor has detected the condition, the actuating device actuates the first and/or second containers, respectively, after a predetermined time period.

20. The dispensing device of claim 19, wherein the actuating device is operable to actuate the first container and/or the second container in a regular time period or a lockout time period,

wherein the actuating device operates in the regular time period if the sensor has not detected the condition, and the actuating device operates in the lockout time period if the sensor has detected the condition,

wherein during the lockout time period, the actuating device actuates the first container and/or the second container after the predetermined time period upon sensing the detected condition;

and

further wherein the actuating device returns to operating in the regular time period upon completion of an actuation of the first container and/or the second container during the lockout time period.
