Abstract

A tracking system includes a global positioning system (GPS) module and a modem for mobile communications both attached to a pet (or other trackee), and a virtual fence (which includes a base station sending a signal to a certain range and a receiver attached to the pet (or other trackee) and receiving the signal sent by a base station when the receiver is within the range of the base station). A portable virtual fence system includes a signal-sending base station, and a signal-receiver worn by a to-be-fenced pet or other trackee. Advantageously, the base station is portable.

Claims

1. A human or animal locating system, comprising:

a tracking device which is associated with said human or animal, said tracking device including a position detection module for detecting a position of said tracking device, said position detection module being selectively activatable;

a base station, said base station and said tracking device being in communication by a radio frequency signal when both said base station and said tracking device are within a signal radius of an RF transmitter or transceiver;

a modem associated with said tracking device for transmitting or receiving signals, data or commands which

selectively transmits a signal through a wireless network when said base station and said tracking device are separated by a distance greater than said signal radius, and

transmits coordinate information through said wireless network obtained from said position detection module;

a battery associated with said tracking device for providing power for at least said modem and said position detection module; and

a service center which

i) receives said signal from said modem,

ii) requests instructions from a remote party based on receipt of said signal from said modem and obtains instructions from said remote party to track said tracking device,

iii) sends a wireless signal which activates said position detection module to detect coordinate information of said tracking device,

iv) receives said coordinate information from said modem, and

v) sends location information to said remote party.

2. The human or animal locating system of claim 1 wherein said service center is a host computer accessible through a computer network.

3. The human or animal locating system of claim 1 wherein said service center includes a telephone center which provides voice communications with said remote party.

4. The human or animal locating system of claim 1 wherein said position detection module includes GPS.

5. The human or animal locating system of claim 1 wherein said position detection module includes at least two different position detecting systems, and wherein the human or animal locating system further comprises a controller for switching between said at least two different position detecting systems.

6. The human or animal locating system of claim 1 further comprising a means for changing said signal radius of said RF transmitter or transceiver.

7. The human or animal locating system of claim 1 further comprising a selectively activatable signal associated with said tracking device, said signal being powered by said battery.

8. The human or animal locating system of claim 7 wherein said selectively activatable signal is a light signal.

9. The human or animal locating system of claim 1 wherein said base station is portable.

10. The human or animal locating system of claim 1 wherein said tracking center includes a means for authenticating a source of said instructions to track said tracking device.

11. The human or animal locating system of claim 1 wherein said tracking center

receives power status information for said battery, and

sends said power status information to said remote party.

12. The human or animal locating system of claim 1 further comprising a monitor, accessible to the remote party, for displaying a map location of said tracking device based on said coordinate information.

13. The human or animal locating system of claim 1 wherein said location information provided by said service center includes a map.

14. The human or animal locating system of claim 1 wherein said location information provided by said service center includes a street address.

15. A method for tracking a human or animal, comprising the steps of:

attaching a tracking device to said human or animal, said tracking device including a position detection module for detecting a position of said tracking device, said position detection module being selectively activatable;

positioning a base station at a desired location;

transmitting a radio frequency signal from an RF transmitter or transceiver of a specified signal radius from one of said tracking device and said base station;

detecting when said base station and said tracking device are separated by a distance greater than said signal radius;

transmitting a signal through a wireless network when said base station and said tracking device are separated by said distance greater than said signal radius to a service center;

determining, by said service center contacting a remote party, whether tracking should proceed;

activating, by said service center, said position detection module to detect coordinate information of said tracking device;

transmitting coordinate information through said wireless network obtained from said position detection module to said service center; and

providing from said service center location information to said remote party based on said coordinate information.

16. The method of claim 15 wherein said service center includes a host computer, wherein said remote party communicates with said host computer by a wireless network.

17. The method of claim 15 wherein said service center includes a telephone center which permits voice communications with said remote party.

18. The method of claim 15 wherein said service center includes a host computer, wherein said remote party communicates with said host computer through the Internet.

19. The method of claim 15 further comprising the step of selectively activating a light signal associated with said tracking device.

20. The method of claim 15 further comprising selectively switching between two different tracking systems within said position detection module.

21. The method of claim 15 further comprising the step of adjusting said signal radius.
