Patent ID: 8892402

Claim:
An apparatus configured and arranged to provide a data interface between equipment, having a plurality of signal lights, to be temporarily monitored and a 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 such that the sensor-engagement member moves laterally with respect to the signal lights; a sensor assembly comprising a plurality of photosensitive receptors disposed in a pattern that corresponds to at least two of the plurality of signal lights as comprise a part of the equipment to be temporarily monitored such that illumination events for each of the at least two of the plurality of 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 lateral position with respect to at least one of the signal lights and then retained in the selected position by the affixment member.
