Abstract

A RFID system applying to a three-dimensional jigsaw is provided. The RFID system includes a jigsaw substrate having a plurality of blocks, a plurality of jigsaw units corresponding to each blocks of the jigsaw substrate, a RFID reader having a plurality of antennas positioned in a position of each blocks of the jigsaw substrate, and a plurality of tags positioned in a position of each face of a three-dimensional jigsaw unit corresponding to the positions of the antennas, wherein the RFID reader communicates to the tags using modulated radio signals through the antennas and the tags respond with modulated radio signals in order to determine whether the orientation of the three-dimensional jigsaw unit is correct or not.

Claims

1. A RFID system applying to a three-dimensional jigsaw, comprising:

a jigsaw substrate having a plurality of blocks;

a plurality of jigsaw units corresponding to each of said blocks of said jigsaw substrate;

a RFID reader having a plurality of antennas respectively positioned in positions of said blocks of said jigsaw substrate; and

a plurality of tags respectively positioned in positions of faces of a three-dimensional jigsaw unit corresponding to said positions of said antennas in order to determine whether an orientation of said three-dimensional jigsaw unit is correct or not.

2. The RFID system, as recited in claim 1, wherein said position of each blocks of said jigsaw substrate is a corner of each blocks of said jigsaw substrate.

3. The RFID system, as recited in claim 1, wherein said antennas positioned in a left-top corner of each blocks of said jigsaw substrate.

4. The RFID system, as recited in claim 1, wherein said antennas positioned in a right-top corner of each blocks of said jigsaw substrate.

5. The RFID system, as recited in claim 1, wherein said antennas positioned in a left-down corner of each blocks of said jigsaw substrate.

6. The RFID system, as recited in claim 1, wherein said antennas positioned in a right-down corner of each blocks of said jigsaw substrate.

7. The RFID system, as recited in claim 1, wherein said position of each face of a three-dimensional jigsaw unit is a corner of each blocks of said jigsaw unit.

8. The RFID system, as recited in claim 1, wherein said tags positioned in a left-top corner of each face of a three-dimensional jigsaw unit.

9. The RFID system, as recited in claim 1, wherein said tags positioned in a right-top corner of each face of a three-dimensional jigsaw unit.

10. The RFID system, as recited in claim 1, wherein said tags positioned in a left-down corner of each face of a three-dimensional jigsaw unit.

11. The RFID system, as recited in claim 1, wherein said tags positioned in a right-down corner of each face of a three-dimensional jigsaw unit.

12. A RFID system applying to a three-dimensional jigsaw, comprising:

a jigsaw substrate having a plurality of blocks;

a plurality of jigsaw units corresponding to each of said blocks of said jigsaw substrate;

a RFID reader having a plurality of antennas respectively positioned in positions of said blocks of said jigsaw substrate; and

a plurality of tags respectively positioned in positions of faces of a three-dimensional jigsaw unit corresponding to said positions of said antennas, wherein said RFID reader communicates to said tags using modulated radio signals through said antennas and said tags respond with modulated radio signals in order to determine whether an orientation of said three-dimensional jigsaw unit is correct or not.

13. The RFID system, as recited in claim 12, wherein said position of each blocks of said jigsaw substrate is a corner of each blocks of said jigsaw substrate.

14. The RFID system, as recited in claim 12, wherein said position of each face of a three-dimensional jigsaw unit is a corner of each blocks of said jigsaw unit.

15. The RFID system, as recited in claim 12, wherein said antennas positioned in a left-top corner of each blocks of said jigsaw substrate.

16. The RFID system, as recited in claim 12, wherein said antennas positioned in a right-top corner of each blocks of said jigsaw substrate.

17. The RFID system, as recited in claim 12, wherein said antennas positioned in a left-down corner of each blocks of said jigsaw substrate.

18. The RFID system, as recited in claim 12, wherein said antennas positioned in a right-down corner of each blocks of said jigsaw substrate.

19. The RFID system, as recited in claim 12, wherein said tags positioned in a left-top corner of each face of a three-dimensional jigsaw unit.

20. The RFID system, as recited in claim 12, wherein said tags positioned in a right-top corner of each face of a three-dimensional jigsaw unit.
