Abstract

A channel (500) is configured and arranged to be fixedly mounted (401) to equipment (100) to be temporarily monitored. At least one sensor-engagement member (800) is movably captivated (402) within this channel and a sensor assembly (1000) (comprising a plurality of photosensitive receptors (1001) that are disposed in a pattern that corresponds to signal lights as comprise a part of the monitored equipment) is biased (404) towards the sensor-engagement member by an affixment member (1200) to thereby retain the sensor assembly in place with respect to the monitored equipment. By this approach, the sensor assembly (in combination with the sensor-engagement member) can be moved (403) along the channel to a selected position with respect to at least one of the signals lights and then retained in that selected position by the affixment member.

Claims

1. An apparatus configured and arranged to provide a data interface between equipment to be temporarily monitored and diagnostic data gathering apparatus, comprising:

a channel configured and arranged to be fixedly mounted to the equipment to be temporarily monitored;

at least one sensor-engagement member movably captivated within the channel;

a sensor assembly comprising a plurality of photosensitive receptors disposed in a pattern that corresponds to signal lights as comprise a part of the equipment to be temporarily monitored such that illumination events for each of the signal lights is detected by a corresponding one of the plurality of photosensitive receptors;

an affixment member configured and arranged to bias the sensor assembly towards the at least one sensor-engagement member to thereby retain the sensor assembly in place with respect to the equipment to be temporarily monitored;

such that the sensor assembly, in combination with a corresponding one of the at least one sensor-engagement member, can be moved along the channel to a selected position with respect to at least one of the signal lights and then retained in the selected position by the affixment member.

2. The apparatus of claim 1 wherein the equipment to be temporarily monitored comprises a Programmable Logic Controller (PLC).

3. The apparatus of claim 2 wherein the equipment to be temporarily monitored comprise at least two Programmable Logic Controllers (PLC'"'"'s).

4. The apparatus of claim 1 further comprising:

an adhesive tape for disposition between the channel and the equipment to be temporarily monitored to thereby secure the channel to the equipment to be monitored.

5. The apparatus of claim 1 wherein the signal lights comprise individual Light Emitting Diodes (LED'"'"'s) and wherein the sensor assembly comprises a same number of photosensitive receptors as there are signal lights in a segregated component area of the equipment to be temporarily monitored.

6. The apparatus of claim 1 wherein the signal lights comprise alphanumeric characters.

7. The apparatus of claim 6 wherein the alphanumeric characters comprise alphanumeric characters that are defined by a light occluding mask such that light passing through the mask forms the alphanumeric characters.

8. The apparatus of claim 1 wherein the sensor assembly comprises a plurality of the sensor assemblies that are each configured and arranged to share the channel.

9. The apparatus of claim 1 wherein the sensor assembly comprises a processor that is operably coupled to the plurality of photosensitive receptors and that is configured and arranged to facilitate detection of the illumination events.

10. The apparatus of claim 9 further comprising an input interface and an output interface, both of which are operably coupled to the processor, to thereby facilitate a transmission of data regarding detected illumination events and to further facilitate daisy-chaining multiple ones of the sensor assemblies to one another.

11. The apparatus of claim 10 wherein the input interface and the output interface are positioned to aid in locating the sensor assembly in the selected position.

12. The apparatus of claim 1 further comprising:

a multiplexer and electro-optical converter that operably couples to the sensor assembly.

13. The apparatus of claim 12 further comprising:

an optical conduit coupled to the multiplexer and electro-optical converter and the diagnostic data gathering apparatus to carry optically-born data regarding the illumination events to the diagnostic data gathering apparatus.

14. The apparatus of claim 1 wherein the sensor assembly comprises:

externally exposed light emitting elements; and

a driver operably coupled to the externally exposed light emitting elements and being configured and arranged to cause the externally exposed light emitting elements to illuminate in a manner that mirrors the illumination events to thereby render those illumination events visible to an observer notwithstanding those illumination events being occluded by the sensor assembly.

15. A method to provide a data interface between equipment to be temporarily monitored and diagnostic data gathering method, comprising:

fixedly mounting a channel to the equipment to be temporarily monitored;

movably disposing at least one sensor-engagement member within the channel such that the at least one sensor-engagement member is partially captivated within the channel;

positioning the at least one sensor-engagement member and a corresponding sensor assembly comprising a plurality of photosensitive receptors disposed in a pattern that corresponds to signal lights as comprise a part of the equipment to be temporarily monitored such that illumination events for each of the signal lights is detected by a corresponding one of the plurality of photosensitive receptors;

using an affixment member to bias the sensor assembly towards the at least one sensor-engagement member to thereby retain the sensor assembly in place with respect to the equipment to be temporarily monitored.

16. The method of claim 15 wherein the equipment to be temporarily monitored comprises a Programmable Logic Controller (PLC).

17. The method of claim 16 wherein the equipment to be temporarily monitored comprise at least two Programmable Logic Controllers (PLC'"'"'s).

18. The method of claim 15 wherein fixedly mounting the channel to the equipment comprises using adhesive tape to secure the channel to the equipment to be monitored.

19. The method of claim 15 wherein the signal lights comprise individual Light Emitting Diodes (LED'"'"'s) and wherein the sensor assembly comprises a same number of photosensitive receptors as there are signal lights in a segregated component area of the equipment to be temporarily monitored.

20. The method of claim 15 wherein the sensor assembly comprises a plurality of the sensor assemblies that are each configured and arranged to share the channel.

21. The method of claim 15 wherein the sensor assembly comprises an input interface and an output interface and wherein positioning the at least one sensor-engagement member and a corresponding sensor assembly comprises using the input interface and the output interface to aid in locating the sensor assembly in the selected position.
