Mobile entity tracking and analysis system
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 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.

Abstract
Method and apparatus for mobile entity tracking and analysis. In some embodiments, a multi-dimensional geophysical area is divided into a first layer of zones. Each zone encompasses a contiguous portion of the geophysical area and has at least one rule assigned thereto. Geoposition values from a sensor attached to a mobile entity are accumulated in a memory, the geoposition values indicative of successive geopositions of the mobile entity. For each accumulated geoposition value, the associated zone in which the geoposition of the mobile entity is located is identified, and the at least one rule assigned to the zone is applied. A second layer zone is subsequently generated responsive to an input signal, and an alarm limit is output based on a subsequently accumulated geoposition value indicating the geoposition of the mobile entity is located within the second layer zone.

6. 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 indicative of successive geopositions of a mobile entity within a selected zone over a selected time interval; 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; using a processing engine to determine a midpoint of the geoposition values; generating an action boundary proximate the midpoint to partition the zone into first and second portions separated by the action boundary; locating the midpoint relative to the action boundary; and outputting an alarm limit responsive to the midpoint falling within the first portion. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. An apparatus comprising:
-
a plurality of sensors each attached to a respective mobile entity within a geophysical area; a receiver which receives a sequence of geoposition packets from each of the respective sensors indicative of instantaneous geoposition of the associated mobile entity, each packet comprising a set of geocoordinates and an associated timestamp indicative of a time at which the mobile entity was at said set of geocoordinates; a mapping engine which defines, in a computer memory, a first layer of zones each corresponding to a different contiguous portion of the geophysical area, the mapping engine further defining at least one rule associated with the mobile entities for each zone; a sampling engine which receives the transmitted packets from the receiver and generates an asynchronous frame as a set of received packets having timestamps within a selected time interval; and a rules application engine which, for each frame, identifies the associated zone in which each of the mobile entities is located, applies the associated rules for the associated frames, and sets an alarm limit value in a memory responsive to a violation of at least one of the rules. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. 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 first sensor attached to 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; 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, wherein the second layer zone is associated with a second mobile entity and the second layer zone moves relative to the geophysical area responsive to changes in geoposition of the second mobile entity as determined from a second sensor attached to the second mobile entity; and outputting an alarm limit responsive to a subsequently accumulated geoposition value from the first sensor or the second sensor indicating the geoposition of the corresponding first mobile entity or second mobile entity has crossed a boundary associated with the second layer zone. - View Dependent Claims (28, 29, 30)
