Abstract

An energy-conserving triggered ID system, comprising: a reading assembly having a normally non-activated state and having a triggered subassembly configurable to activate the reading assembly; and a mobile assembly having no power source and having a triggering subassembly configurable to activate the triggered subassembly when the mobile assembly is located within a triggering range, wherein the reading assembly is operable to transfer power to the mobile assembly and wherein data transfer is effected between the mobile assembly and the reading assembly within a data transfer range.

Claims

1. An energy-conserving triggered ID system, comprising:

a. a reading assembly having a normally non-activated state and having a triggered subassembly configurable to activate the reading assembly; and

b. a mobile assembly having no power source and having a triggering subassembly configurable to activate the triggered subassembly when the mobile assembly is located within a triggering range,

c. wherein the reading assembly is operable to transfer power to the mobile assembly and wherein data transfer is effected between the mobile assembly and the reading assembly within a data transfer range.

2. An ID system according to claim 1, wherein the reading assembly is deactivatable _[GT6]upon completion of data transfer.

3. An ID system according to claim 2, wherein the reading assembly is powerable by a battery.

4. An ID system according to claim 3, wherein the reading assembly is powerable by mains power.

5. An ID system according to claim 3, wherein the data transfer range is at least the same as the triggering range.

6. An ID system according to claim 5, wherein the mobile assembly is an RFID device.

7. An ID system according to claim 6, wherein the triggering subassembly includes at least one magnetic unit.

8. The ID system according to claim 7, wherein the magnetic unit is a permanent magnet.

9. An ID system according to claim 6, wherein the triggered subassembly includes at least one magnetically activated switch/sensor.

10. An ID system according to claim 3, wherein the ID system is operable to use power from the battery for at least one year.

12. The method of claim 1, whereby the reading assembly is deactivated upon completion of data transfer.

13. The method of claim 12, wherein the reading assembly is powered by a battery.

14. The method of claim 12, wherein the reading assembly is powered by mains power.

15. The method of claim 13, wherein the data transfer range is at least the same as the triggering range.

16. The method of claim 15, wherein the mobile assembly is an RFID device.

17. The method of claim 16, wherein the triggering subassembly includes at least one magnetic unit.

18. The method of claim 17, wherein the magnetic unit is a permanent magnet.

19. The method of claim 13, wherein the triggered subassembly includes at least one magnetically activated switch/sensor.

20. The method of claim 13, wherein the ID system operates from the battery for at least one year.

11. A method of operating an energy-conserving triggered ID system, comprising the steps of:

a. configuring a reading assembly having a normally non-activated state and having a triggered subassembly to activate the reading assembly;

b. taking a mobile assembly having no power source and having a triggering subassembly to activate the triggered subassembly when the mobile assembly is located within a triggering range; and

c. operating the reading assembly to transfer power to the mobile assembly and effecting data transfer between the mobile assembly and the reading assembly within a data transfer range.
