Abstract
Objects are located within at least one mapped field region. Environments for location tracking are mapped through a configuration setup flexibly supporting multiple objects with precision and speed. Host and Repeater devices are located at vertices of polyhedra defining spaces. Polyhedra edge lengths are defined as the modified physical distance between two devices. This morphing employs parameters measured by or input to the system. Morphed three dimensional subzones are defined within the volume of the polyhedra defined by the devices at the vertices.
Claims16
A system for object location tracking within a field region comprising:
- at least one tag associated with an object;
- at least one host, wherein said at least one host determines attributes of field generated by at least one of said at least one tag and said at least one host, whereby location of said at least one tag in said field region is determined from said attributes;
- wherein said object location tracking comprises mapping said field region;
- wherein said mapping comprises field parameters;
- and
- wherein said mapped field parameters comprise tag to host Received Signal Strength Indication (RSSI) and host to tag RSSI.
A method for tracking objects comprising the steps of:
- measuring field attributes of a region;
- identifying at least one object from said measured attributes;
- determining at least a location of said object from said measured attributes;
- and
- calibrating to determine said attributes of said field of said region whereby said field of said region is mapped for attributes.
A system for object tracking within a field region comprising:
- at least one object comprising at least one tag;
- at least one host;
- and
- at least one repeater, wherein said at least one repeater determines attributes of a field generated by said at least one object comprising at least one tag and is in communication with said at least one host, whereby a three-dimensional spatial location of said at least one object in said field region is determined from said attributes, wherein false location messages are ignored for said tags not in attribute database, field mapping attributes comprise Extensible Markup Language (XML) documents, and said object tracking comprises out of network information, purge time, and configurable sleep time defining message check frequency whereby efficiency is increased.
