Abstract

One embodiment of the present invention is an RFID system comprising a first detector at a first position and a second detector at a second position. An RFID edge server can include software to check the first and second detector to determine a direction of an object. The direction information can be used to trigger the start or stop of the collection of data for an RFID detector.

Claims

1. An RFID system comprising:

a first detector at a first position;

a second detector at a second position; and

an RFID edge server including software to check the first and second detector to determine a direction of an object, the direction information used to trigger the start or stop of the collection of data for an RFID detector.

2. The RFID system of claim 1, wherein if the first detector triggers followed by the second RFID detector, a first direction is indicated.

3. The RFID system of claim 1, wherein if the second detector triggers followed by the first detector a second direction is indicated.

4. The RFID system of claim 1, wherein the start and stop of the collection of data is defined by an ECSpec.

5. The RFID system of claim 4, wherein the ECSpec includes a start condition trigger defined by the direction.

6. The RFID system of claim 4, wherein the ECSpec includes a stop condition trigger defined by the direction.

7. The RFID system of claim 1, wherein the first and second detectors are photoelectric sensors.

8. The RFID system of claim 1, wherein the first and second detectors are used to produce a directional trigger for an ECSpec.

9. An RFID system comprising:

a first detector at a first position;

a second detector at a second position; and

an RFID edge server including software to check the first and second detector to determine a direction of an object, the direction information used to trigger the start or stop of the collection of data for an RFID detector, wherein the start and stop of the collection of data is defined by an ECSpec.

10. The RFID system of claim 9, wherein if the first detector triggers followed by the second RFID detector, a first direction is indicated.

11. The RFID system of claim 9, wherein if the second detector triggers followed by the first detector a second direction is indicated.

12. The RFID system of claim 11, wherein the ECSpec includes a start condition trigger defined by the direction.

13. The RFID system of claim 11, wherein the ECSpec includes a stop condition trigger defined by the direction.

14. The RFID system of claim 9, wherein the first and second detectors are photoelectric sensors.

15. The RFID system of claim 9, wherein the first and second detectors are used to produce a directional trigger for an ECSpec.

16. A method comprising:

receiving signals from a first detector at a first position and from a second detector at a second position;

using the signals to produce directional information; and

using the directional information to trigger the start or stop of the collection of data for an RFID detector.

17. The method of claim 16, wherein if the first detector triggers followed by the second RFID detector, a first direction is indicated.

18. The method of claim 16, wherein if the second detector triggers followed by the first detector a second direction is indicated.

19. The method of claim 16, wherein the start and stop of the collection of data is defined by an ECSpec.

20. The RFID system of claim 19, wherein the ECSpec includes a start condition trigger defined by the direction.

21. The RFID system of claim 19, wherein the ECSpec includes a stop condition trigger defined by the direction.

22. The method of claim 16, wherein the first and second detectors are photoelectric sensors.

23. The method of claim 16, wherein the first and second detectors are used to produce a directional trigger for an ECSpec.
