Compact spray device
A power source is provided to a dispensing unit that includes a housing having an aerosol container disposed therein. A sleep period interval between spray operations is selected and a motion sensor is activated to detect motion within a sensory path of the sensor after completion of the sleep period interval. If no motion is detected by the motion sensor a fluid is automatically discharged from the aerosol container and the sleep interval is reset and if motion is detected by the motion sensor a delay time interval is initiated and fluid is not discharged from the aerosol container. The dispensing unit alternates between activating the sensor to detect motion and resetting the delay time interval until no motion is detected by the motion sensor at the expiration of the delay time interval, which results in the automatic discharge of fluid and a resetting of the sleep period interval.
1. A method of operating a dispensing unit, comprising:
providing a power source to a dispensing unit that includes a housing having an aerosol container disposed therein;
selecting a sleep period interval between spray operations; and
activating a motion sensor disposed on the dispensing unit to detect motion within a sensory path of the sensor after completion of the sleep period interval,
wherein after completion of the sleep period interval if no motion is detected by the motion sensor a fluid is automatically discharged from the aerosol container and the sleep interval is reset, and
wherein after completion of the sleep period interval if motion is detected by the motion sensor a delay time interval is initiated and fluid is not discharged from the aerosol container, and the dispensing unit alternates between activating the sensor to detect motion and resetting the delay time interval until no motion is detected by the motion sensor at the expiration of the delay time interval, which results in the automatic discharge of fluid from the aerosol container and a resetting of the sleep period interval.
2. The method according to claim 1 further including the step of continuously monitoring for motion after the sensor detects motion upon completion of the sleep period interval, wherein the delay time interval is not initiated until the sensor does not detect any further motion.
3. The method according to claim 1 further including the step of continuously monitoring for motion during the delay time interval, wherein detection of motion causes the sensor to further continuously monitor for motion and reset the delay time interval after no further motion is detected.
4. The method according to claim 1 , wherein the delay time interval comprises about two minutes or less.
5. The method according to claim 1 , wherein the sleep period interval comprises about 15 minutes or more.
