Abstract

An apparatus for indicating the location of a signal emitting tag. The apparatus includes signal detectors, control logic, and at least one light producing device. The control logic activates the light producing device in response to receiving data from the signal detectors. After activation, the light producing device illuminates the location of an individual that is near the point of origin of a signal that was detected by the signal detectors.

Claims (30)

1. An apparatus for indicating the location of a signal emitting tag, the apparatus comprising:

a plurality of signal detectors;

a signal emitting tag emitting a signal to the plurality of signal detectors, the signal emitting tag carried by an individual that is collocated with a point of origin of said signal;

a control logic receiving the signal from the plurality of signal detectors;

a first set of instructions within the control logic that identify a location of the signal based on known locations of the plurality of signal detectors;

at least one visible light producing device that is activated by the control logic in response to receiving data from the plurality of signal detectors and the identified location of said signal; and

the at least one visible light producing device that, in response to being activated by the control logic, illuminates the location of the signal using the at least one visible light producing device to identify the point of origin of the signal emitting tag based on the signal collocated with the individual; and

a second set of instructions within the control logic that monitor the point of origin of the signal emitting tag, based, at least in part, on the data from the plurality of signal detectors, for readjusting orientation of the visible light producing device to continuously illuminate the point of origin of the signal.

2. The apparatus of claim 1 , wherein the plurality of signal detectors detect the signal, and send data to the control logic in response to the detection of the signal, and wherein the control logic is configured to triangulate a location of the point of origin of the signal based on the data.

3. The apparatus of claim 1 , wherein the data received by the control logic includes a respective strength of the signal as detected by a signal detector included in the plurality of signal detectors.

4. The apparatus of claim 1 , wherein the data received by the control logic includes a respective time that the signal is detected by a signal detector included in the plurality of signal detectors.

5. The apparatus of claim 1 , wherein the plurality of signal detectors includes:

a first signal detector that sends a first data to the control logic in response to detecting the signal;

a second signal detector that sends a second data to the control logic in response to detecting the signal; and

a third signal detector that sends a third data to the control logic in response to detecting the signal.

6. The apparatus of claim 5 , wherein the control logic is configured to triangulate the location of the point of origin of the signal based on the first data, the second data, and the third data.

7. The apparatus of claim 6 , wherein the triangulation of the location of the point of origin of the signal is based, at least in part, on a respective strength of the signal that was received by the first signal detector, the second signal detector, and the third signal detector.

8. The apparatus of claim 6 , wherein the triangulation of the location of the point of origin of the signal is based, at least in part, on a respective time that the signal was received by the first signal detector, the second signal detector, and the third signal detector.

9. The apparatus of claim 5 , wherein the first signal detector is located above a floor such that the distance between the first signal detector and the floor allows for the passage of the individual.

10. The apparatus of claim 5 , wherein a distance between the second signal detector and the third signal detector allows for the passage of the individual between the second signal detector and the third signal detector.

11. The apparatus of claim 10 , wherein the at least one visible light producing device, when activated, indicates the location of the point of origin of the signal between the second signal detector and the third signal detector.

12. The apparatus of claim 1 , wherein the signal is generated by a radio frequency identification tag.

13. The apparatus of claim 1 , wherein the at least one visible light producing device illuminates the location of the point of origin of the signal to identify said individual as the individual actual carrying the signal emitting tag from a number of other individuals located within range of said one or more plurality of signal detectors.

14. The apparatus of claim 5 , wherein the at least one visible light producing device comprises a plurality of visible light producing devices that, when activated, indicate the location of the point of origin of the signal in at least two dimensions, said first dimension residing above the signal emitting tag and said second dimension residing below the signal emitting tag.

15. The apparatus of claim 1 , wherein the control logic responds to the reception of data from the plurality of signal detectors by triggering an alaiin.

16. The apparatus of claim 1 , wherein the control logic responds to the reception of data from the plurality of signal detectors by initiating a video recording session.

17. The apparatus of claim 16 , wherein the control logic responds to the reception of data from the plurality of signal detectors by overlaying a display of the location of the point of origin of the signal onto the video captured during the video recording session.

18. The apparatus of claim 1 , wherein the at least one visible light producing device illuminates an area that includes the point of origin of the signal.

19. The apparatus of claim 1 , wherein the at least one visible light producing device, when activated, indicates at least one point on a pathway taken by the individual.

20. The apparatus of claim 1 , wherein the control logic responds to a change in the location of the point of origin of the signal by changing the indicated location of the individual such that the indicated location of the individual corresponds to the change in the location of the point of origin of the signal.
