Abstract
An object movement and location detection system and method is provided. A locating circuit is substantially secured to the object. A plurality of monitoring units is positioned remotely from the locating circuit, each in a different location. A first omnidirectional signal is intermittently communicated between the locating circuit and the plurality of monitoring units. A movement sensor is substantially secured to the object, wherein the movement sensor detects a movement of the object. A calculator is in communication with each of the plurality of monitoring units and the movement sensor, wherein the calculator determines a duration of transmission time of the first omnidirectional signal between each of the monitoring units and the locating circuit and calculates a location of the locating circuit using the determined duration of transmission time for each of the monitoring units and the locating circuit subsequent to a detected movement of the object.
