Abstract
A system for detection and tracking of objects which carry low radio frequency tags that comprise an inductive antenna and transceiver operable at a radio frequency below 1 megahertz, a transceiver operatively connected to that antenna, an ID data storage device, a microprocessor for handling data from the transceiver and data store, and an energy harvesting device to capture energy from an energy condition at said object. The system includes a field communication inductive antenna disposed, preferably at a distance of several feet from each object, and at an orientation that permits effective communication with the tag antennas at the aforesaid radio frequency, a data receiver, transmitter and reader data processor in operative communication with the field communication inductive antenna. The aforesaid tag communication inductive antenna may have a ferrite core to enhance data reception.
