Abstract:
1. A computer-implemented method comprising: dividing a multi-dimensional geophysical area into a first layer of zones, each zone encompassing a contiguous portion of the geophysical area and having at least one rule assigned thereto; accumulating, in a memory, geoposition values from a sensor attached to a mobile entity indicative of successive geopositions of the mobile entity; for each accumulated geoposition value, identifying the associated zone from the first layer of zones in which the geoposition of the mobile entity is located and applying the at least one rule assigned to the associated zone; subsequently generating a second layer zone responsive to an input signal, the second layer zone encompassing a contiguous portion of the geophysical area that overlays at least a portion of at least one zone in the first layer of zones, the second layer zone maintaining a constant size and moving over time relative to the geophysical area; and outputting an alarm limit responsive to a subsequently accumulated geoposition value from the sensor indicating the geoposition of the mobile entity is located within the second layer zone.
