Abstract

There is disclosed a method and apparatus for an object locator system (10) for requesting and obtaining information about the location of a mobile object, having attached thereon a lightweight object locator (42), operable in a region served by a two-way paging system (12) and a global positioning satellite system (50). The object locator (42) may be selectively activated to conserve power or enabled to respond only when beyond or within a boundary. Further, the object locator system (10) may provide the location information in several forms including rectangular or polar coordinates referred to a base station (18) or origin, position on a map display, etc. In alternate embodiments the two-way paging system (12) may be substituted by a direct wireless link or a satellite relay communications link; the location information may be translated into human readable form either before or after transmission from the object locator; the location information may be presented at an output as selectable text; spoken message or graphic display including a map; the location information may have associated therewith other information such as time the location was determined, the status of the object locator, the condition of the battery, position of the object locator relative to a boundary or electronic fence or to indicate an alarm condition; or the location information may be accessed or delivered by dial-up or automatic means.

Claims

1. A method comprising:

wirelessly receiving location signals at a device coupled to an animate object;

activating at least a portion of the device to process location signals for determining location information;

automatically deactivating the portion of the mobile device after determining the location information;

identifying a location threshold associated with the animate object;

determining a violation of the location threshold based, at least in part, on the location information, wherein the violation is determined by the device coupled to the animate object.

2. The method of claim 1, further comprising periodically activating at least a portion of the device to receive location signals for determining location information.

3. The method of claim 1, further comprising activating at least a portion of the device in response to at least wirelessly receiving a request.

4. The method of claim 1, further comprising wirelessly transmitting, from the device, a notification of the violation.

5. The method of claim 4, further comprising:

receiving from a user device a request for location information after transmitting the notification;

automatically determining location information associated with the animate object in response to at least the request; and

wirelessly transmitting the location information to the user device.

6. The method of claim 1, wherein the location signals comprise Global Positioning Satellite (GPS) signals.

7. The method of claim 1, wherein the location threshold comprises at least one of a distance, a time, an azimuth heading, an altitude, or a perimeter.

8. The method as claimed in claim 1, further comprising:

receiving a notification of an animate object violating a location threshold, the notification wirelessly transmitted from a device coupled to the animate object; and

displaying location information associated with the animate object on a map based, at least in part, on the notification.

9. The method of claim 8, wherein the location information comprises at least one of a longitude and latitude, one or more street names proximate the animate object, or an azimuth heading and a distance from the animate object.

10. A system comprising:

a memory operable to store a location threshold associated with an animate object;

one or more processors operable to;

wirelessly receive location signals;

activate at least a portion of the device to process location signals for determining location information;

automatically deactivate the portion of the mobile device after determining the location information;

identify the location threshold associated with the animate object; and

determine a violation of the location threshold based, at least in part, on the location information,

wherein the system is coupled to the animate object.

11. The system as claimed in claim 10, further comprising:

a memory operable to store location information; and

one or more processors operable to;

receive a notification of an animate object violating a location threshold, the notification wirelessly transmitted from a device coupled to the animate object; and

display the location information associated with the animate object on a map based, at least in part, on the notification.

12. The system of claim 11, wherein the location information comprises at least one of a longitude and latitude, one or more street names proximate the animate object, or an azimuth heading and a distance from the animate object.

13. The system of claim 10, the processors further operable to periodically activate at least a portion of the device to receive location signals for determining location information.

14. The system of claim 10, the processors further operable to activate at least a portion of the device in response to at least wirelessly receiving a request.

15. The system of claim 10, the processors further operable to wirelessly transmit, from the device, a notification of the violation.

16. The system of claim 15, the processors further operable to:

receive, from a user device, a request for location information after transmitting the notification;

automatically determine location information associated with the animate object in response to at least the request; and

wirelessly transmit the location information to the user device.

17. The system of claim 10, wherein the location signals comprise Global Positioning Satellite (GPS) signals.

18. The system of claim 10, wherein the location threshold comprises at least one of a distance, a time, an azimuth heading, an altitude, or a perimeter.
