Mobile entity tracking and analysis
First Claim
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 associated with a mobile entity indicative of successive geopositions of the mobile entity;
using the accumulated geoposition values to identify an 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 expanding 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.

Abstract
Method for tracking and analysis of a mobile entity. In some embodiments a multi-dimensional geophysical area is divided into a first layer of zones each encompassing a contiguous portion of the geophysical area and having at least one rule. Geoposition values from a sensor associated with a mobile entity are accumulated in a memory. The accumulated geoposition values are used to identify an associated zone from the first layer of zones in which the mobile entity is located and the at least one rule assigned to the associated zone is applied. A second layer zone is subsequently generated in response to an input signal. The second layer zone overlays at least a portion of one zone in the first layer and expands over time. An alarm limit is output in response to a subsequently accumulated geoposition value from the sensor indicating the mobile entity is in the second layer zone.

10. 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 associated with a motor vehicle and defining a safety zone proximate the vehicle; 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, the alarm limit operative to adjust at least one selected operation of the motor vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. 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, a plurality of geoposition values from a first sensor associated with a first mobile entity indicative of successive geopositions of the first mobile entity; for each accumulated geoposition value, identifying the associated zone from the first layer of zones in which the geoposition of the first mobile entity is located and applying the at least one rule assigned to the associated zone; 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 associated with a second mobile entity and moving relative to the geophysical area responsive to changes in geoposition of the second mobile entity as determined from a second sensor associated with the second mobile entity; and outputting an alarm limit responsive to subsequently accumulated geoposition values from the first and second sensors indicating a separation distance between the first and second mobile entities has crossed a predetermined threshold level. - View Dependent Claims (18, 19, 20)
