PROXIMITY DETECTION SYSTEMS AND METHODS
First Claim
1. A proximity detection system comprising:
- at least one processor configured todefine a first virtual zone around a piece of equipment,determine a location of a person,define a second virtual zone around the person at the location, and as the location of the person changes,determine a direction of travel of the person,automatically modify the second virtual zone to extend a first distance in the direction of travel of the person and extend in a second distance opposite the direction, wherein the first distance is greater than the second distancecompare the first virtual zone and the second virtual zone, andin response to at least a portion of the second virtual zone overlapping with at least a portion of the first virtual zone, perform at least one action.

Abstract
Methods and systems for detecting a person located around a piece of equipment. One system includes processor configured to define a first virtual zone around a piece of equipment, determine a location of a person, and define a second virtual zone around the person at the location. As the location of the person changes, the processor is further configured to determine a direction of travel of the person, and automatically modify the second virtual zone to extend a first distance in the direction of travel of the person and extend in a second distance opposite the direction, wherein the first distance is greater than the second distance. In response to at least a portion of the second virtual zone overlapping with at least a portion of the first virtual zone, the processor is configured to perform at least one action.

13. A method for detecting at least one person located around a piece of equipment, the method comprising:
-
determining a first virtual zone around the piece of equipment, determining a location of the person, defining, with at least one processor, a second virtual zone around the person, and as the location of the person changes, determining a direction of travel of the person, automatically modifying the second virtual zone to extend a first distance in the direction of travel of the person and extend in a second distance opposite the direction, wherein the first distance is greater than the second distance comparing the first virtual zone and the second virtual zone, and in response to at least a portion of the second virtual zone overlapping with at least a portion of the first virtual zone, performing at least one action. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. Non-transitory computer-readable medium including instructions that, when executed by a processor, cause the processor unit to perform a set of functions, the set of functions comprising:
-
determining a first virtual zone around the piece of equipment, determining a location of the person, defining, with at least one processor, a second virtual zone around the person, and as the location of the person changes, determining a direction of travel of the person, automatically modifying the second virtual zone to extend a first distance in the direction of travel of the person and extend in a second distance opposite the direction, wherein the first distance is greater than the second distance comparing the first virtual zone and the second virtual zone, and in response to at least a portion of the second virtual zone overlapping with at least a portion of the first virtual zone, performing at least one action.
