Chronometric, communication, identification, and tracking tag
First Claim
1. A chronometric location and tracking system, comprising:
- a locator indicating a geographic location of an item coupled to said locator;
a two-way radio system activating said locator to transmit a reply signal to determine location of said locator;
a base unit having at least three antennas, said base unit transmitting a first signal;
a first receiver operatively coupled to and traveling with said locator, said first receiver receiving said first signal;
a first transmitter operatively coupled to said first receiver, said first transmitter transmitting a reply signal when activated by said first receiver;
said base unit receiving said reply signal and determining a relative position of said locator from at least one antenna;
said first signal containing a timing pulse;
said receiver detecting said timing pulse and providing synchronization with said first signal; and
said reply signal being synchronized with said first signal and transmitted at a different frequency than said first signal such that relative distance of said locator to at least one antenna may be determined.

Abstract
A chronometric identification and location tag for an animal, such as a dog, that incorporates a variety of detection and sensing functions as well as communication capacities. Assembled in a compact form that allows ready transport on a trainable animal, such as a dog, the chronometer identification and location tag enables the location of the associated animal, as well as the transmission and reception of information and data. Specific embodiments include the use of GPS to provide location data, as well as an alternative location system using temporary or permanent antenna installations. Hazardous material, visual, and acoustic detectors and other sensors and/or generators may be used in conjunction with transmission facilities for providing data regarding the animal'"'"'s environment. Information and signals may be transmitted to the central controller by a receiver and a speaker can provide for audio signaling to the animal or others close to the animal in an audible range of the speaker.
