Abstract

An identification system for identifying objects, according to one embodiment, includes a plurality of objects to be identified within an area, with a transponder being fitted to one respective object and operable to transmit a code radio frequency signal representing an identification code. The system includes an activation part that is remote from the respective object and is operable to transmit an activation radio frequency signal via a wireless connection to the transponder of the respective object so that the transmitting part transmits the code radio frequency signal. A receiving part that is remote from the respective object is operable to receive the code radio frequency signal via a wireless connection. The system also includes a device that is operable to move the activation part and receiving part within the area such that the two parts are moved continuously along a predetermined path which is in the form of circulatory path that is complementary to a shape of the area and to an arrangement of the objects in the area and such that activation part and the receiving part are moved past each respective object.

Claims

1-4. -4. (canceled)

5. An identification system for identifying objects, comprising:

a plurality of objects to be identified, the objects being disposed within an area;

a transponder that is fitted to one respective object and operable to transmit a code radio frequency signal representing an identification code;

an activation part that is remote from the respective object and is operable to transmit an activation radio frequency signal via a wireless connection to the transponder of the respective object so that the transmitting part transmits the code radio frequency signal;

a receiving part that is remote from the respective object and is operable to receive the code radio frequency signal via a wireless connection; and

a device that is operable to move the activation part and receiving part within the area such that the two parts are moved continuously along a predetermined path which is in the form of circulatory path that is complementary to a shape of the area and to an arrangement of the objects in the area and such that activation part and the receiving part are moved past each respective object.

6. The identification system according to claim 5, wherein the reception part and the activation part are integrated form a single activation/reception unit.

7. The identification system according to claim 5, wherein the reception part and activation part are moved, in a controlled manner, along the predetermined path at a predetermined speed.

8. The identification system according to claim 7, wherein the speed of the activation part and of the reception part being less than or equal to 30 cm/s.

9. The identification system according to claim 7, wherein the speed of the activation part and of the reception part being less than or equal to 15 cm/s.

10. The identification system according to claim 7, wherein the speed of the activation part and of the reception part being less than or equal to 10 cm/s.

11. The identification system according to claim 5, wherein the area is within a closed room and the circulatory path is defined by an annular track with the objects being disposed radially outward from the annular track.

12. The identification system according to claim 5, wherein the transponder is coupled to the object and faces the activation part and reception part.

13. The identification system according to claim 5, wherein the device for moving the activation part and reception part includes a carriage that supports the activation part and the reception part and is driven along a pair of guide rails that define the predetermined circulatory path.

14. The identification system according to claim 5, wherein the area is within a closed room and the circulatory path is defined by an oval shaped track with the objects being disposed radially outward from the oval shaped track.

15. The identification system according to claim 5, wherein the objects are arranged radially outward from the circulatory path and movement of the activation part and the reception part results in the transponders of the objects receiving activation radio signals from respective activation parts from a first set of angles and the transponders return the code radio frequency signals to the respective reception parts at a second set of angles different from the first set of angles.

16. The identification system according to claim 5, wherein the activation part and the reception part are arranged in such that they transmit and receive, respectively, in opposite directions in a direction that is substantially perpendicular top the predetermined path.

17. The identification system according to claim 5, wherein the objects are stationary within the area.

18. An identification system for identifying objects, comprising:

a plurality of objects to be identified, the objects being disposed within an area;

a transponder that is fitted to one respective object and operable to transmit a code radio frequency signal representing an identification code;

an activation part that is remote from the respective object and is operable to transmit an activation radio frequency signal via a wireless connection to the transponder of the respective object so that the transmitting part transmits the code radio frequency signal;

a receiving part that is remote from the respective object and is operable to receive the code radio frequency signal via a wireless connection; and

a device that is operable to move the activation part and receiving part within the area such that the two parts are moved continuously along a predetermined path which is in the form of a linear path that is complementary to a shape of the area and to an arrangement of the objects in the area, which are located along both sides of the linear path, and such that activation part and the receiving part are moved past each respective object.

19. A method for identifying objects, comprising the steps of:

attaching one transponder to each object to be identified;

providing an activation part, that can transmit an activation radio frequency signal, and a reception part, that can receive a code radio frequency signal;

transporting, in a continuous manner, the activation part and the reception part along a circulatory shaped path and past the objects;

transmitting an activation radio frequency signal from the activation part to the transponder via a wireless connection;

transmitting, by the transponder, the code radio frequency signal representing an identification code via a wireless connection;

receiving the code radio frequency signal at the reception part via a wire-free connection resulting in each respective object being identified.

20. An identification system for identifying a plurality of objects, comprising:

means for transmitting a code radio frequency signal representing an identification code, the transmitting means being configured to be coupled to each object;

activation means for transmitting an activation radio frequency signal via a wire-free connection to the transmitting means associated with one object to cause the transmitting means to transmit the code radio frequency signal;

means for receiving the code radio frequency signal via a wire-free connection; and

means for continuously transporting the means for activation and means for receiving past each object and along a circulatory path, with the objects being located radially outward from the transporting means.
