Abstract

A system and method are disclosed for remote testing of items where the tests are performed at a first site and monitored and controlled at a second site. A first remote test control station at the first site includes a test bench device for testing the items, and a video meeting station for viewing and controlling the test bench device. The second site includes a remote test control station, where the second remote test control station can control the testing parameters of the test equipment used by the test bench device, in near real time. The second remote test control station at the second site and the video meeting station at the first site are connected via both voice/audio links and visual links.

Claims

1. A system for remote testing of electrical components, comprising:

a remote test control station;

a test bench device for testing a unit under test (UUT);

a video meeting station connected to the test bench device, wherein the video meeting station comprises means for capturing visual information and sending the visual information to the remote test control station, means for audio communication with the remote test control station, and means for receiving video information from the remote test control station; and

means for controlling test parameters by the remote test control station, wherein the test parameters are used by the test bench device to control diagnostic equipment used to test the electrical component,

wherein the remote test control station comprises means for audio communication with the video meeting control station, means for receiving video information from the video meeting control station, and means for displaying diagnostic information output from the test bench device in near real-time.

2. The system as recited in claim 1, wherein the video meeting station and the test bench device are integrated as one physical system.

3. The system as recited in claim 1, wherein the means for capturing visual information is a camera selected from a group consisting of an inexpensive, low-resolution video camera and a high-resolution video camera.

4. The system as recited in claim 1, wherein the means for audio communication is a communication means selected from a group consisting of a standard telephone connection and a Web-enabled voice link.

5. The system as recited in claim 1, wherein the means for receiving video information is an interactive service displaying video information on a display window.

6. The system as recited in claim 1, wherein the means for controlling test parameters further comprises:

an interactive service running on both the test bench device and the remote test control station;

software for controlling diagnostic/test equipment running on the test bench device; and

means for taking control of the software for controlling diagnostic/test equipment via the interactive service.

7. The system as recited in claim 6, wherein the interactive service operates over one or more firewalls.

8. The system as recited in claim 1, wherein the remote test control station further comprises means for capturing visual information and sending the visual information to the video meeting station.

9. The system as recited in claim 8, wherein the remote test control station further comprises a second test bench device for testing a second UUT concurrently with the UUT being tested by the first test bench device.

10. The system as recited in claim 9, wherein a test conducted at the second test bench device at the remote test control station is monitored at the video meeting station for training purposes.

11. The system as recite in claim 10, wherein the second test bench device further comprises a second means for controlling test parameters, wherein the first means for controlling test parameters further comprises a first interactive service running on both the test bench device and the remote test control station, and wherein the second means for controlling test parameters further comprises a second interactive service running on both the second test bench device and a computing device at the video meeting station.

12. The system as recited in claim 11, wherein both the first test bench device and the video meeting station are part of an integrated physical system.

13. The system as recited in claim 10, wherein both the first test bench device and the video meeting station are part of an integrated physical system.

14. The system as recited in claim 1, further comprising a remote viewing site for monitoring a test conducted at one of the first test bench device and the second test bench device.

15. The system as recited in claim 14, wherein the remote viewing site comprises means for receiving video and audio information from a test bench device.

16. A method for remote testing of electrical components, said method comprising steps of:

(a) testing a unit under test (UUT), by a testing team, using a test procedure developed to correspond to a specification, wherein a monitoring team remotely controls test parameters of the test and monitors the testing remotely via a video and audio link to the testing team;

(b) determining by the monitoring team whether the UUT passed the testing;

(c) communicating between the testing team and the monitoring team, if the UUT failed the testing, to determine whether the UUT is acceptable;

(d) fixing, if necessary, at least one feature of the UUT; and

(e) repeating steps (a) through (d) for the fixed UUT, until the UUT passes the testing.

17. The method as recited in claim 16, wherein determining whether the UUT is acceptable includes a determination of whether test requirements are waivable or whether the UUT needs to be redesigned.

18. The method as recited in claim 16, wherein the monitoring team remotely controls test parameters using an interactive service which allows the testing team to authorize the monitoring team to control parameters of software controlling test equipment, the test equipment being used to conduct the test, and wherein the monitoring team remotely controls the test parameters in near real time during the test.

19. The method as recited in claim 18, further comprising a step of training the testing team by the monitoring team during the testing.

20. The method as recited in claim 18, wherein the monitoring team views output of the test equipment and video of the test conducted at the testing team site on one display monitor in a plurality of display areas, in near real time.

21. A method for remote testing of an item of manufacture, said method comprising steps of:

(a) testing an item under test (IUT), by a testing team, using a test procedure developed to correspond to a specification;

(b) remotely monitoring, by a monitoring team, the testing via a video and audio link to the testing team, wherein the monitoring occurs in near real time, and wherein the monitoring team views output of the test equipment and a video of the test equipment on one display monitor; and

(c) remotely controlling parameters of the test equipment, by the monitoring team, at the invitation of the testing team.

22. The method as recited in claim 21, further comprising steps of:

(d) determining by the monitoring team whether the IUT passed the testing;

(e) communicating between the testing team and the monitoring team, if the IUT failed the testing, to determine whether the IUT is acceptable.

(f) fixing, if necessary, at least one feature of the IUT; and

(g) repeating steps (a) through (f) for the fixed IUT until the IUT passes the testing.

23. The method as recited in claim 22, wherein determining whether the IUT is acceptable includes a determination of whether test requirements are waivable or whether the IUT needs to be redesigned.

24. The method as recited in claim 21, further comprising steps of:

monitoring of the testing by at least one additional team, at the invitation of the testing team.

25. The method as recited in claim 22, further comprising steps of:

remotely controlling parameters of the test equipment, by one of the at least one additional teams, at the invitation of the testing team.
