Apparatus and method for locating individuals and objects using tracking devices
Abstract
A system for monitoring objects and individuals. In this system, a monitoring station is remotely accessible through a user interface. The interface is adapted to provide a visually cognizable rendering of an area and a tool useful for selecting at least a portion of said area, and to communicate a first request signal to provide location coordinates of a first tracking device. The first tracking device comprises a first transceiver adapted to receive the first request signal, and to transmit a first reply signal that comprises a first identification code. In addition, a second tracking device having a second transceiver is adapted to receive the first reply signal, compare the first identification code to a stored identification code, and communicate to the monitoring station a second reply signal that comprises location coordinates of the first tracking device in part responsive to verification of the first identification code.

1. A system comprising:
a first tracking device having a first transceiver configured to receive a first request signal and to transmit a first reply signal that comprises first location data, a first microprocessor configured to process a first request signal provided through a user interface that is remotely located, and a first identification code communicated as part of a first reply signal; and
a second tracking device having a second tracking transceiver adapted to receive the first reply signal, and verify the first identification code as a recognized code, and in response communicate a second reply signal that comprises a second identification code to the first tracking device;
wherein the first tracking device is adapted to calculate, in response to the second reply signal, a distance between the first and the second devices, and communicate an adjustment signal that comprises at least one of verbal and audio queues that indicates directional information of the first tracking device relative to the second tracking device. |
