Abstract

A method of operating a dispensing unit including the steps of applying a power source to a dispensing unit that includes a container and performing a startup procedure in response to applying the power source. The startup procedure includes performing an activation sequence that discharges a fluid from the container. The method further includes the step of performing an active mode procedure after the startup procedure without providing a lockout period in between. The active mode procedure includes activating a motion sensor associated with the dispensing unit, performing an activation sequence that discharges the fluid from the container when the motion sensor detects motion, and performing a transition procedure.

Claims

1. A method of operating a dispensing unit, comprising the steps of:

applying a power source to a dispensing unit that includes a container;

performing a startup procedure in response to applying the power source, wherein the startup procedure includes performing an activation sequence that discharges a fluid from the container;

performing an active mode procedure after the startup procedure without providing a lockout period therebetween, wherein the active mode procedure includes activating a motion sensor associated with the dispensing unit, performing an activation sequence that discharges the fluid from the container when the motion sensor detects motion, and performing a transition procedure.

2. The method of claim 1, wherein the step of performing the transition procedure includes providing a lockout period during which the motion sensor is deactivated and performing a subsequent active mode procedure after the expiration of the lockout period, and wherein the length of the lockout period is selectable by a user.

3. The method of claim 1, wherein the step of performing the transition procedure includes providing a timeout period during which the motion sensor is deactivated, performing one or more automatic activation sequences during the timeout period, and performing a subsequent active mode procedure after the expiration of the timeout period.

4. The method of claim 3, wherein a user can select one or more of the length of the timeout period, the number of automatic activation sequences during the timeout period, and the timing of the one or more automatic activation sequences during the timeout period.

5. The method of claim 1, wherein the step of performing the transition procedure includes performing subsequent activation sequences in response to the motion sensor detecting subsequent motion and providing a timeout period during which the motion sensor is deactivated only after performing one or more subsequent activation sequences.

6. The method of claim 5, wherein a user can select the number of subsequent activation sequences to be performed before providing the timeout period.

7. The method of claim 1, wherein the step of performing the transition procedure includes performing one or more activation sequences each time motion is sensed.

8. The method of claim 7, wherein a user can select the number of activation sequences performed each time motion is sensed.

9. The method of claim 1, wherein the step of performing the startup procedure further includes the steps of providing an indication that the dispensing unit is functioning properly, providing a sleep period that lasts about five seconds, providing an indication that the activation sequence is about to be performed, and performing the activation sequence.

10. A method of operating a dispensing unit, comprising the steps of:

applying a power source to a dispensing unit that includes a container;

performing a startup procedure in response to applying the power source, wherein the startup procedure includes providing a sleep period of about five seconds and performing an activation sequence that discharges a fluid from the container immediately after the sleep period has elapsed; and

performing an active mode procedure after the startup procedure, wherein the active mode procedure includes activating a motion sensor associated with the dispensing unit, performing an activation sequence that discharges the fluid from the container when the motion sensor detects motion, and performing a transition procedure,

wherein the transition procedure includes providing a timeout period during which the motion sensor is deactivated, performing one or more automatic activation sequences during the timeout period, and performing a subsequent active mode procedure after the expiration of the timeout period.

11. The method of claim 10, wherein the active mode procedure is performed after the startup procedure without a timeout period therebetween, and wherein the user can select one or more of the length of the timeout period, the number of automatic activation sequences during the timeout period, and the timing of the one or more automatic activation sequences during the timeout period.
