Abstract

A corner sensor assembly includes a housing having at least one magnet attached thereto, wherein the magnets allow the corner sensor assembly to be readily attached and relocated to corner structures within a building. The assembly includes at least one motion sensor for detecting motion within two opposing fields of monitoring. At least one visual indicator is activated when the motion sensors detect motion within both fields of monitoring and are deactivated when no motion is sensed in at least one of the fields of monitoring. The assembly includes an integrated power supply located within the housing.

Claims

1. A method for sensing movement at an intersection of at least two joining pathways within a building, said method comprising:

attaching a corner sensor assembly to a corner formed by said at least two joining pathways, said corner sensor assembly having a housing, a power supply operatively connected to said housing, at least two motion sensors operatively connected to said housing and said power supply, and at least one warning indicator operatively connected to said housing and said power supply;

monitoring a first field of monitoring in one of said at least two joining pathways for motion at said intersection with one of said at least two motion sensors;

monitoring a second field of monitoring in another of said at least two joining pathways for motion at said intersection with another of said at least two motion sensors;

activating at least one of said at least one warning indicator when motion is sensed in either said first field of monitoring or said second field of monitoring.

2. The method of claim 1 further comprising de-activating said at least one visual indicator when no motion is sensed in both said first field of monitoring and said second field of monitoring.

3. The method of claim 1, wherein said at least one warning indicator is a visual indicator or an audible indicator.

4. The method of claim 1, wherein said power supply is positioned within said housing.

5. The method of claim 1, wherein when motion is sensed in one of said first field of monitoring or said second field of monitoring, said at least one activated warning indicator is detectable in the other field of monitoring.

6. The method of claim 1, wherein said corner sensor assembly includes a plurality of magnets attached to said housing for removably attaching said corner sensor assembly to said corner.

7. A corner sensor assembly for releasable attachment to a corner structure, said corner sensor assembly comprising:

a housing having an integrated power supply positioned within said housing;

a pair of motion sensors for sensing motion within separate and non-overlapping fields of monitoring, wherein said motion sensors are operatively connected to said housing and said power supply; and

at least one warning indicator changeable between an active state and an inactive state for providing a warning signal of a potential collision in response to motion sensed within at least one of said fields of monitoring, each of said at least one warning indicator being operatively connected to said housing, said power supply, and each of said at least two motion sensors.

8. The corner sensor assembly of claim 7, wherein one of said at least one warning indicator is a visual indicator or an audible indicator.

9. The corner sensor assembly of claim 8, wherein said at least one warning indicator includes a pair of visual indicators, and each visual indicator is directed toward separate fields of monitoring, and wherein each visual indicator is activated when motion is detected within the opposing field of monitoring relative to the field of monitoring to which said visual indicator is directed.

10. The corner sensor assembly of claim 7, wherein each of said pair of motion sensors continually monitors said field of monitoring and provides an output.

11. The corner sensor assembly of claim 10, wherein said output from each of said motion sensors includes an active output when motion is sensed within said field of monitoring of said motion sensor or an inactive output when no motion is sensed within said field of monitoring of said motion sensor.

12. The corner sensor assembly of claim 10 further comprising a controller operatively connected to said housing, said pair of motion sensors, said power supply, and said at least one warning indicator, said controller continually receiving said output from said pair of motions sensors, wherein said controller activates said at least one warning indicator when motion is sensed in at least one of said fields of monitoring.

13. A corner sensor assembly for releasable attachment to a corner structure, said corner sensor assembly comprising:

a housing having a power supply positioned within said housing;

a first motion sensor operatively connected to said housing and said power supply, said first motion sensor sensing motion within a first field of monitoring;

a second motion sensor operatively connected to said housing and said power supply, said second motion sensor sensing motion within a second field of monitoring;

at least one warning indicator changeable between an active state and an inactive state for providing a warning signal of a potential collision at said corner, said at least one warning indicator being operatively connected to said housing, said power supply, and said first and second motion sensors; and

a controller operatively connected to said housing, said first and second motion sensors, and said at least one warning indicator;

wherein said first and second motion sensors continually monitor said first and second fields of monitoring, and each of said first and second motion sensors provides an output to said controller; and

wherein said controller activates one of said at least one warning indicator when motion is sensed in either said first field of monitoring or said second field of monitoring or both of said fields of monitoring.

14. The corner sensor assembly of claim 13, wherein said output from said first motion sensor is an active output when motion is sensed in said first field of monitoring and said output from said first motion sensor is an inactive output when no motion is sensed in said first field of monitoring;

and wherein said output from said second motion sensor is an active output when motion is sensed in said second field of monitoring and said output from said second motion sensor is an inactive output when no motion is sensed in said second field of monitoring.

15. The corner sensor assembly of claim 14, wherein said controller changes said at least one warning indicator from an inactive state to an active state when said output from either said first motion sensor or said second motion sensor is an active output, and wherein said controller changes said at least one warning indicator from an active state to an inactive state when said output from both said first motion sensor and said second motion sensor is an inactive output.

16. The corner sensor assembly of claim 13, wherein at least one warning indicator includes a first warning indicator directed toward said first field of monitoring and a second warning indicator directed toward said second field of monitoring, and wherein said controller activates said first warning indicator when said controller receives an active output from said second motion sensor, and said controller activates said second warning indicator when said controller receives an active output from said first motion sensor.

17. The corner sensor assembly of claim 16, wherein said first and second warning indicators are selected from the list including a visual indicator and an audible indicator.

18. The corner sensor assembly of claim 16, wherein said first and second warning indicators are overrideable in which said first and second warning indicators switched to a continuous active state.
